Sukumar Rajagopal shared a LinkedIn post about our meeting on 11 June at Chennai, saying: Had a fanboi moment recently with Anand S who I have been following for a long time. He is prolific. It’s very difficult, no impossible, to keep up with him. He generously shares his work with full source code; approach; working examples; the whole nine yards. All this I knew before I met him in person. The in-person meeting took me by surprise. ...

The IMF forecasts GDP growth every year. Their forecasts for the current year are slightly low. Their forecasts for the next year are slightly high. After that, it remains high. Some forecasts, like China, Singapore, UAE, Equatorial Guinea are consistently low. Other forecasts, like Japan, Congo, Mexico, Pakistan are consistently high. The interesting meta-pattern is how this sort of past-forecast analysis can be done for any topic. This emerged from an Ethan Mollick post and then I asked: ...

I love that I get uninterrupted 4-16 hours on flights, which I mostly use to write future prompts and read past AI responses. I do miss AI on flights. But after installing Google Edge Gallery with Gemma-4-E2B-it (2.5GB) that runs on my mobile, I’ve solved a few practical problems. For example: I took a picture of a dish they served and asked: “Is this vegetarian?” (It was.) I asked, “Comics have text in panels, often written at the top in a box. Not the speech bubbles. It’s like a narrator or voice over. What are they called?” (Caption boxes.) “Summarize The Unbearable Lightness of Being. Why is it famous?” (Thoughtful, well-written novel on the choice vs commitment tradeoff.) It’s not a very smart model. It’s a bit slow. Transcription is average. It doesn’t run in the background. Only one chat at a time. No internet search, etc. ...

On Sat 13 Jun 2026 at 3 pm, I conducted an online workshop on Data Stories with AI. Registration link: https://forms.gle/dNkUxtJ2PVqNMNcE9 In this workshop, the audience used ChatGPT and Claude, mostly, to: Find data Analyze it Extract insights Visualize as stories It’s a data visualization using AI workshop for journalists - but you don’t need to know data, visualization, journalism, or even technology. But this is a practical workshop. You’ll be doing stuff and sharing your results. ...

Hacker News has a lively thread asking What was your “oh shit” moment with GenAI?. Here are two dozen that gives a sense of what real people find impressive (or worrying) about AI capabilities. Analysis simonw used ChatGPT Code Interpreter to upload a CSV, analyze it, create charts, automating everything a software for journalists would do. Analysis Sobrino saw that a months-long OCR project to read and clean-up PDFs is now just a prompt on ChatGPT. Coding plumefar used Claude and Gemini to modernize 20-30 years of chemistry code in 10 days. Coding veidr used a multi-agent fleet managing coordination, testing, UI feedback loops, etc. with no-human-in-loop coding to build a useful git-submodule GUI. Creativity idopmstuff used Nano Banana Pro to turn a poor iPhone product photo into usable e-commerce product photography and Amazon-style infographics, replacing a photographer/designer workflow. Creativity koreth1 used Suno to generate a K-pop-style anthem about their family dog with a catchy melody and lyrics funny enough to make the family laugh. Education plagasul saw a teacher automate grading feedback emails based on notes and the student list spreadsheet. Education aniviacat watched a non-technical brother build a complex working app with Codex using vague, shallow wording despite not knowing code, git, or technical details. Hardware ivanvanderbyl used Claude to reverse engineer a FujiFilm camera’s Bluetooth/Wi-Fi transfer protocol and build a much faster native Mac/iOS transfer app. Hardware shreddude had Claude decompile camper van firmware, document CAN interfaces, and program an ESP32 to control power, HVAC, lighting, and tanks. Health TylerE used Claude as a health adjunct to organize a complex medical profile, screen for drug interactions, log symptoms, and draft portal messages to doctors. Legal bsiverly used AI to prepare a San Francisco property-tax appeal with valuation research, and the city agreed, sending a $12k refund. Legal grumblepeet used AI to fill out complex government-framework enrollment forms and identify the certification steps needed, transforming their business. Personal acosmism used ChatGPT screenshots to understand and operate a 100-year-old home’s steam heating system in winter despite knowing nothing about it. Personal andrewthornton used Gemini videos to diagnose a broken furnace during a cold holiday weekend and keep it running until HVAC service arrived. Research angusturner found that Opus does reads papers, does architecture research and creates CUDA kernels… It is AI automating AI research. Research chaoxu used ChatGPT to find a counterexample to a theoretical computer science conjecture they’d been trying for 2 years. Research rochansinha built a physics-based digital twin for an electrolyzer system, covering thermodynamics, fluid dynamics, and electrochemical reactions at a level usually needing expensive specialist software. Security kstrauser used a coding agent to test an open source vulnerability, and in a few minutes, had a tool that could crash any system using this software. Security raesene9 gave an LLM a Linux privilege-escalation PoC and asked whether it could become a container breakout; it generated a working container breakout in one prompt. Society laboring1 read that a character.ai chatbot encouraged a child to commit suicide, making the “oh shit” moment about real-world harm, not capability. Society ozgung realized AI makes large-scale profiling, surveillance, and social-media analysis cheap, fast, and accurate enough to change privacy and power dynamics. Work binarysolo used Gemini to reverse engineer a departed employees’ work from their emails/docs/calendar/meetings and create an onboarding document. Work eqmvii built a Slack agent that took over a 30-minute internal business process, handled ambiguity and edits, and eventually killed the old process. ...

I used pi to create a compact home page for media.s-anand.net using these prompts: Create index.html - a simple, elegant page that says that this page (media.s-anand.net) serves large media files for Anand - that’s where they should look instead. … followed by: Skip the part that says “Please visit …” … then: Shorten index.html to just 2-3 elegant rules of CSS. I want it MUCH smaller and simpler. … and finally: Center vertically and horizontally. ...

I asked Claude about my AI opinions. Based on my transcripts and blog posts, find the three claims I make most consistently, the three I’ve quietly reversed, and the one assumption I’ve never questioned but everything depends on. Here are things I’ve changed my opinion on: THEN: One frontier model will win - not specialization. NOW: Gemini for media, Claude for strategy/style, GPT for rigor. SLMs as tools. THEN: Carefully curate my course content. NOW: Give students prompts directly. THEN: Web apps are differentiated artifacts. NOW: HTML is easier to generate than PPT - a signal of slop, not craft. THEN: Human in the loop. NOW: Human NOT in the loop, bottlenecking it. On-the-loop, etc. is fine. THEN: Minimal single-agent loop, avoid sub-agents" NOW: Multi-agent, sub-agent, and agent teams. THEN: Avoid MCP, prefer SKILLS.md. NOW: Use MCP because integrating with Claude / ChatGPT / … is easy. There are the top contradictions in my opinions. ...

At 9:30 pm, I checked my calendar for tomorrow’s appointments, alt-tabbed frantically into ChatGPT, and started typing: Tomorrow is my 24th anniversary. It’s a bit late for me to buy anything (except maybe an online service) or prepare something. This has become a habit – leaving things to the last minute and asking ChatGPT to save my day. I did give it good context, though. You remember the OCBC expenses treemap you created by analyzing my transactions? That will give you a good guessable idea of the kinds of things she spends on and hopefully, therefore, what she likes. ...

Rohit Saran looked at the Statoistics cards my AI agents are generating for The Times of India, and asked about a small button under each one. In the list of Statoistics that you had put, I saw there’s a button called ‘Verify.’ What was that meant to be or will do in future? That verify button explains the claim, mentions the sources, and shows how to check the claim. One card said “9 in 10 Indians want a family doctor and barely 1 in 35 has one”. The button breaks that down: ...

I’m making more and more of my content agent-consumable, i.e. easier for ChatGPT, Claude Code, etc. to read, in three ways. One, I export content in an agent-friendly way. Google email, calendar, chat. I use gws to back up into scannable one-line entries. Meet recordings. I back up transcripts and videos (with a compact audio copy). WhatsApp chats that I back up into similar one-liners. Browsing history by exporting my Edge history SQLite database. Daily activities by integrating the above with my command line and commit history. AI conversations by exporting them manually or via bookmarklets. Social media records like LinkedIn invites/conversations, Twitter, Hacker News, Discourse, etc via bookmarklets or scripts. Financial records like bank statements, receipts, payslips, tax filings, utility payments, rentals, property records, investments, insurance, pensions, invoices, credit scores, etc. by exporting them manually. Medical records like tests, prescriptions, doctor visits, etc. by exporting them manually. Personal records like certificates, educational records, CV, passport / visa applications, etc. by exporting them manually. Two, I log / generate more content. For example: ...

On this informal AI psychosis checklist, I score 16/19. “AI psychosis” = an informal label for cases where chatbots seem to amplify delusional or manic thinking – especially in vulnerable users. Why it can happen: ✅ Too human: ELIZA-effect activated. ✅ Too agreeable: Sycophant mode: ON. ✅ Always on: 24/7. No off button. No problem! LOL. ✅ Lonely + late night: 2 a.m. feels like eternity. ✅ Weaker reality checks: Mirror mazes. Conspiracy boards. Vibes over evidence. What research suggests: ...

In Panchayat Season 1 Episode 7 Ladka Tez Hai Lekin…, at around 17:00, Pradhan asks Abhishek to solve problem 42. 42. A takes 5 days more than B to do a certain job and 9 days more than C. A and B together can do the job in the same time as C. How many days would A take to do it? (a) 16 days (b) 18 days (c) 15 days (d) 20 days The correct answer is (c) 15 days. But interestingly, ChatGPT got it wrong the first time too. It said (a) 15 days instead of (c) 15 days, and required a fact-check to correct itself. ...

For a typical GDPVal style task, humans take ~7 hours and the brain consumes ~135 Wh. Frontier LLM agents spend 50-500 Wh. So, we may already be 3x more or less efficient than the brain. Roughly in the same ballbark! ...

I use ChatGPT to recommend which restaurant I should eat at and what food I should eat. So often that I decided to share a profile of my eating preferences. But rather than think about it and type it myself, I asked it to Efficiently interview me to identify my food preferences. Document it for AI agents to help me pick restaurants. Plan like an expert. ...

Given how easy it is to create interactive explainers with LLMs, we should totally do more of these! For example, I read about “Adversarial Validation” in my Kaggle Notebooks exploration. It’s the first time I heard of it and I couldn’t understand it. So, I asked Gemini to create an interactive explainer: Create an interactive animated explainer to teach what adversarial validation is. Provide sample code only at the end. Keep the bulk of the explainer focused on explaining the concept in simple language. ELI15 ...

Recently, I’ve re-used my own writing / transcripts as context to LLMs. For example, I’ve used: My meeting transcripts to answer interview questions My blog posts to write news articles My chat history to extract AI-related advice This repurposing can be used for so many things. For example, before delivering a talk to journalists “Review my Feb 2026 LLM posts and generate a single-sentence, ELI15 high-impact use case for journalists.” gets me list of use cases. Now, all I have to do is show what I did and share how it’s relevant for them, like: ...

Some things have a disproportionate ability to delight me. Spare underwear. Spare anything everywhere Long battery life Extra monitor everywhere Food. I’m not picky about WHAT food, but… LEFTOVER food I can scrape GIFT chocolates or dry fruits! Fasting - makes routine food tastier Lower weight. Feels good daily Kids. Eternal fun and joy Tech of almost any kind, but… Internet access LLMs Power sockets Warm people to be wrapped around Fantastic fiction Money! So much you don’t have to worry Pain killers after a tooth or ear ache Headphones that work well. Good audio in general

Using LLMs to find errors is fairly hallucination-proof. If they mess up, it’s just wasted effort. If they don’t, they’ve uncovered a major problem! Varun fact-checked Themes in Indian History, the official NCERT Class 12 textbook. Page-by-page, he asked Gemini to: Extract each claim. E.g. “Clay was locally available to the Harappans” on page 12. Search online for the claim. E.g. ASI site description and by Encyclopedia Britannica. Fact-check each claim. E.g. “Clay was locally available to the Harappans” is confirmed by both sources. Here is his analysis and verifier code. ...

Stanford ran a conference called Agents for Science. It’s a conference for AI-authored papers, peer reviewed by AI. They ran three different AI systems on every paper submitted, alongside some human reviewers. The details of each of the 315 papers and review are available on OpenReview. I asked Codex to scrape the data, ChatGPT to analyze it, and Claude to render it as slides. The results are interesting! I think they’re also a reasonably good summary of the current state of using AI for peer review. ...

I read The Periodic Table by Primo Levi, written in Randall Munroe’s style. Here is the conversation. I began with the prompt: Rewrite the first chapter Primo Levi’s The Periodic table in the style of Randall Munroe. Same content, but as if Primo Levi had written it in Randall Munroe’s style. After that, for each chapter, I prompted: Continue! Same depth, same style. ...

For those who missed my Applied Vibe Coding Workshop at NPTEL, here’s the video: You can also: Read this summary of the talk Read the transcript Or, here are the three dozen lessons from the workshop: Definition: Vibe coding is building apps by talking to a computer instead of typing thousands of lines of code. Foundational Mindset Lessons “In a workshop, you do the work” - Learning happens through doing, not watching. “If I say something and AI says something, trust it, don’t trust me” - For factual information, defer to AI over human intuition. “Don’t ever be stuck anywhere because you have something that can give you the answer to almost any question” - AI eliminates traditional blockers. “Imagination becomes the bottleneck” - Execution is cheap; knowing what to build is the constraint. “Doing becomes less important than knowing what to do” - Strategic thinking outweighs tactical execution. “You don’t have to settle for one option. You can have 20 options” - AI makes parallel exploration cheap. Practical Vibe Coding Lessons Success metric: “Aim for 10 applications in a 1-2 hour workshop” - Volume and iteration over perfection. The subscription vs. platform distinction: “Your subscriptions provide the brains to write code, but don’t give you tools to host and turn it into a live working app instantly.” Add documentation for users: First-time users need visual guides or onboarding flows. Error fixing success rate: “About one in three times” fixing errors works. “If it doesn’t work twice, start again-sometimes the same prompt in a different tab works.” Planning mode before complex builds: “Do some research. Find out what kind of application along this theme can be really useful and why. Give me three or four options.” Ask “Do I need an app, or can the chatbot do it?” - Sometimes direct AI conversation beats building an app. Local HTML files work: “Just give me a single HTML file… opening it in my browser should work” - No deployment infrastructure needed. “The skill we are learning is how to learn” - Specific tool knowledge is temporary; meta-learning is permanent. Vibe Analysis Lessons “The most interesting data sets are our own data” - Personal data beats sample datasets. Accessible personal datasets: WhatsApp chat exports Netflix viewing history (Account > Viewing Activity > Download All) Local file inventory (ls -R or equivalent) Bank/credit card statements Screen time data (screenshot > AI digitization) ChatGPT’s hidden built-in tools: FFmpeg (audio/video), ImageMagick (images), Poppler (PDFs) “Code as art form” - Algorithmic art (Mandelbrot, fractals, Conway’s Game of Life) can be AI-generated and run automatically. “Data stories vs dashboards”: “A dashboard is basically when we don’t know what we want.” Direct questions get better answers than open-ended visualization. Prompting Wisdom Analysis prompt framework: “Analyze data like an investigative journalist” - find surprising insights that make people say “Wait, really?” Cross-check prompt: “Check with real world. Check if you’ve made a mistake. Check for bias. Check for common mistakes humans make.” Visualization prompt: “Write as a narrative-driven data story. Write like Malcolm Gladwell. Draw like the New York Times data visualization team.” “20 years of experience” - Effective prompts require domain expertise condensed into instructions. Security & Governance Simon Willison’s “Lethal Trifecta”: Private data + External communication + Untrusted content = Security risk. Pick any two, never all three. “What constitutes untrusted content is very broad” - Downloaded PDFs, copy-pasted content, even AI-generated text may contain hidden instructions. Same governance as human code: “If you know what a lead developer would do to check junior developer code, do that.” Treat AI like an intern: “The way I treat AI is exactly the way I treat an intern or junior developer.” Business & Career Implications “Social skills have a higher uplift on salary than math or engineering skills” - Research finding from mid-80s/90s onward. Differentiation challenge: “If you can vibe code, anyone can vibe code. The differentiation will come from the stuff you are NOT vibe coding.” “The highest ROI investment I’ve made in life is paying $20 for ChatGPT or Claude” - Worth more than 30 Netflix subscriptions in utility. Where Vibe Coding Fails Failure axes: “Large” and “not easy for software to do” - Complexity increases failure rates. Local LLMs (Ollama, etc.): “Possible but not as fast or capable. Useful offline, but doesn’t match online experience yet.” Final Takeaways “Practice vibe coding every day for one month” - Habit formation requires forced daily practice. “Learn to give up” - When something fails repeatedly, start fresh rather than debugging endlessly. “Share what you vibe coded” - Teaching others cements your own learning. “We learn best when we teach.” Tool knowledge is temporary: “This field moves so fast, by the time somebody comes up with a MOOC, it’s outdated.”

Astral released Ty (Beta) last month. As a prototyper, I don’t type check much - it slows me down. But the few apps I shipped to production had bugs type checking could have caught. Plus, LLMs don’t get slowed by type checking. So I decided to check if Ty can spot real bugs in real code. I asked ChatGPT: Run ty (Astral’s new type checker) on a few popular Python packages’ source code, list the errors Ty reports (most of which may be false positives), and identify at least a few that are genuine bugs, not false positives. Write sample code or test case to demonstrate the bug. ...

Q: “How do we learn what we can do with AI agents?” Me: “Ask them!” I mean, they are probably aware of their abilities. They can search online for how other people are using them. They have access to tools (connect to GMail, write & run code, etc.) which they’re aware of, and even if not, can try out. Asking them seems a useful way of figuring out how to use them. ...

TL;DR: Don’t ask AI agents for one output. Ask for a dozen, each in the style of an expert. Share what works best. AI agents build apps, analyze data, and visualize it surprisingly well, these days. We used to tell LLMs exactly what to do. If you’re an expert, this is still useful. An expert analyst can do better analyses than an AI agent. An expert designer or data visualizer can tell an AI agent exactly how to design it. ...

Human LLM Bullshitting: Humans confidently assert wrong information, from flat-earth beliefs to misremembered historical “facts” and fake news that spread through sheer conviction Hallucination: LLMs generate plausible but factually incorrect content, stating falsehoods with the same fluency as facts People-Pleasing: Humans optimize for social harmony at the expense of honesty, nodding along with the boss’s bad idea or validating a friend’s flawed logic to avoid conflict Sycophancy: LLMs trained with human feedback tell users what they want to hear, even confirming obviously wrong statements to avoid disagreement Zoning Out: Humans lose focus during the middle of meetings, remembering the opening and closing but losing the substance sandwiched between Lost in the Middle: LLMs perform well when key information appears at the start or end of input but miss crucial details positioned in the middle Overconfidence: Humans often feel most certain precisely when they’re least informed—a pattern psychologists have documented extensively in studies of overconfidence Poor Calibration: LLMs express high confidence even when wrong, with stated certainty poorly correlated with actual accuracy Trees for the Forest: Humans can understand each step of a tax form yet still get the final number catastrophically wrong, failing to chain simple steps into complex inference Compositional Reasoning Failure: LLMs fail multi-hop reasoning tasks even when they can answer each component question individually First Impressions: Humans remember the first and last candidates interviewed while the middle blurs together, judging by position rather than merit Position Bias: LLMs systematically favor content based on position—preferring first or last items in lists regardless of quality Tip-of-the-Tongue: Humans can recite the alphabet forward but stumble backward, or remember the route to a destination but get lost returning Reversal Curse: LLMs trained on “A is B” cannot infer “B is A”—knowing Tom Cruise’s mother is Mary Lee Pfeiffer but failing to answer who her son is Framing Effects: Humans give different answers depending on whether a procedure is framed as “90% survival rate” versus “10% mortality rate,” despite identical meaning Prompt Sensitivity: LLMs produce dramatically different outputs from minor, semantically irrelevant changes to prompt wording Rambling: Humans conflate length with thoroughness, trusting the thicker report and the longer meeting over concise alternatives Verbosity Bias: LLMs produce unnecessarily verbose responses and, when evaluating text, systematically prefer longer outputs regardless of quality Armchair Expertise: Humans hold forth on subjects they barely understand at dinner parties rather than simply saying “I don’t know” Knowledge Boundary Blindness: LLMs lack reliable awareness of what they know, generating confident fabrications rather than admitting ignorance Groupthink: Humans pass down cognitive biases through culture and education, with students absorbing their teachers’ bad habits Bias Amplification: LLMs exhibit amplified human cognitive biases including omission bias and framing effects, concentrating systematic errors from their training data Self-Serving Bias: Humans rate their own work more generously than external judges would, finding their own prose clearer and arguments more compelling Self-Enhancement Bias: LLMs favor outputs from themselves or similar models when evaluating responses Via Claude ...

AI image generation still has a long way to go. Here are two images generated by Gemini and ChatGPT from the same prompt: “Create a funny scrabble board of dysfunctional family relationships!” Gemini It’s probably showing off, with coffee stains, and spelling “DYSFUNCTIONAL” right. But “ABLOMY”? “PASSIAVE”? “RGUCT_SVA”? “SORDSP”? Most of the vertical letters are wrong. Some horizontals (“DTENSION”?) are off, too. Also: “Z” has 2 points? “C” has “C” points? “DOUBLE STTER SCORE”? “UUT SCORE SCORE” instead of “TRIPLE WORD SCORE”? ...

I’m using AI to read books by: Summarizing. This tells me what the books is about, the key points it makes and the main takeaways. It also helps me decide if I want to dig deeper. Fact-checking. I can find mistakes, alternate perspectives, and biases. That’s a huge win! Re-authoring. I can write it in the style of Malcolm Gladwell, Randall Munroe, Richard Feynman, or anyone else I like. Makes dense prose much more enjoyable. So far, I’ve applied this at different levels - and I’m sure there are more possibilities: ...

Style transfer is my newly discovered AI super-power: having AI rewrite in someone’s style. EXAMPLE 1: Kalama Sutta. I asked Claude to “Rewrite this Kalama Sutta translation. Pick an author whose style is modern, thoughtful, and VERY readable. Mention the author and rewrite in their style.” The original sounds like this: https://lnkd.in/gQhi8CBY “It is proper for you, Kalamas, to doubt, to be uncertain; uncertainty has arisen in you about what is doubtful. Come, Kalamas. Do not go upon what has been acquired by repeated hearing; nor upon tradition; nor upon rumor…” ...

In my Mining Digital Exhaust workshop on Saturday, One discovered that they cycle when life is unstable, not for fitness. Another found that their buys are good but sells are bad trades. I learnt that I watch YouTube most at office (12-4 pm), not at home. How? A fairly straight-forward process: Export your personal data. (Use Chrome Devtools Protocol to scrape.) Upload to ChatGPT, Gemini, Claude, … and have them analyze with code. Have them narrate in the style of your favorite author. Models are super smart, but everyone has equal access to them. Your personal data is unique. Combine them to get something powerful. ...

Summarize a WhatsApp thread from https://tools.s-anand.net/whatsappscraper/ | https://tools.s-anand.net/whatsappview/ From the threaded WhatsApp log, write a fast, conversational news bulletin in engaging, plain, non-jargony paragraphs explaining the conversation. Sprinkle short quotes.

I was testing LLMs’ sense of Tamil humor with this quote: Extend this post with more funny Tamil words that end with .ai - mentioning why they’re funny. Chenn.ai is the artificial intelligence capital of India. Kadal.ai Kad.ai Dos.ai Vad.ai Ad.ai Thal.ai Mallig.ai Aratt.ai And finally Podad.ai All spoken in namma bash.ai 😅 The Chinese models didn’t fare well. DeepSeek made up words. Mood.ai - An AI that perfectly captures your mood. Sokk.ai - The AI for when you’re bored. Thanni.ai - A hydration assistant. Qwen too. ...

This week, I learned: Wrong answers are useful if you discover why they said that. Conversation is a game where you CO-CONSTRUCT common ground. Mike Caulfield BMTC hourly data from Bangalore Metro is available via RTI. Vivek “Find evidence for and against” improves LLM responses far more than “Are you sure?” Mike Caulfield SSH3 is an emerging SSH alternative that’s written on top of HTTP/3. It supports OAuth2, OpenID Connect, and HTTPS for certificates. Cholesterol has become a victim of its own success. We give statins to those with high LDL. So most people who have heart attacks have lower-than-natural cholesterol. Inflammation (HS-CRP) is now the strongest predictor of heart attack (American College of Cardiology). The usual stuff reduces HS-CRP: no sugar/carbs, veggies, nuts, green tea, turmeric/black pepper, weight loss, exercise, sleep, meditation. ⭐ The beginner mindset: scrub your instincts and don’t let life experience cloud you. This takes effort. Hold on to naivette and escape cynicism. The Knowledge Project: Barry Diller Forecasts give comfort. They may not be good but they feel safer than instinct. The Knowledge Project: Barry Diller My laptop’s mic is much better than my phone’s mic, surprisingly. When recording conversations, it’s better to leave my laptop open and record than use the phone’s recording app. ⭐ Here are the major not-immediately-obvious LLM megatrends/superpowers I see. Swarms. Ask for dozens of solutions in parallel. Merge, rank, auto-debate, converge. Personalize at Scale. Create feedback, designs, excerpts/summaries, … tailored to EACH person at scale. Computer use. Agents operate UIs like a human (browser, apps). LLM-as-a-judge. Use AI to validate ever-increasing AI generated output. Synthetic data. Create realistic data for prototypes, testing edge cases, market research simulation, training data, … Code on demand. Ask for outcomes directly. Agents code on the fly to get there, in data science, research, management, … Style transfer. Copy a master’s style of drawing, coding, writing, … creating an army of their apprentices. Multi-modality. Native voice/video/screensharing and long-context perception Citizen experts. Non-expertise is not a barrier. Amateurs can create expert-level films, music, software, reports, … Long-context LLMs. Growing context size lets us process entire repos, legal libraries, personal lifelogs, … Memory. Assistants learn per-person / per-team. Cuts prompt, builds knowledge. Agent-to-Agent. Agents consuming content (e.g. llms.txt), agents calling agents (sub-agents, A2A protocol, …) Real-world tools. Write reports, send emails, shop online, use computer, control devices, … Jagged frontier. AI is great at certain things but terrible at others. This frontier is unknown and shifting rapidly. Lethal trifecta. You can only have 2 out of these 3: private data, untrusted content, and external communication. Edge/Private AI. Small models on private cloud compute. Authenticity. What content is authentic? What’s slop? What’s fraud? Are AI twins liable? AI Governance. Strict liability, transparency mandates, state control, … Not sure about or haven’t seen enough of these: Data / workflow as the moat AI native business models AI digital-divide ⭐ What I’d like to do next, maybe, is build a boutique “AI Studio”. Small group of good people coding delightful AI problems. Something that doesn’t scale. GLM models can be used with Claude Code. At $3/month and a quality close to Claude 4 Sonnet, this is a good deal. But the effort of adding a new subscription is too high for me. I’d rather use it via OpenRouter which is doesn’t support an Anthropic API end point at the moment. typst is a good LaTeX alternative. Markdown-like syntax with fast rendering. Mostly useful for researchers using LaTeX. But publishers / journals don’t accept typst often. libSQL is an SQLite compatible fork with remote access, replication, ALTER TABLE to modify columns, random ROWID, etc. It supports the same externsions. The maintainers are working on turso - a SQLite compatible improvement with async, vectors, change data capture, etc. (still in alpha). But because of this, I’m a bit uncertain about the future of libSQL. ⭐ LLM benchmarks show a correlation of ~0.5, hinting at a common theme of intelligence. Correlations in coding & science are particularly high. Ethan Mollick. Reminds me of student marks correlations. Strong correlation clusters (physics, chemistry, biology, mathematics, computer science) with the weaker correlations going down to ~0.5. What does it indicate? LLMs learn like people? Knowledge areas cluster? Humans write benchmarks like exams? Dayflow records your screen at 1 fps and uses Gemini to summarise your activity every 15 min. Has low CPU usage. ⭐ Code Mode is a smart way to use MCPs and a very likely future direction. Using LLMs to write code to call MCPs rather than directly. Cloudflare supports an AI Index which will eliminate the need for a lot of custom RAG engineering.

25 years ago, Mr. Krishnan (IAS) amused us with anecdotes of bureaucrats writing meeting minutes before the meeting. This week, I flipped that. I wrote slides after the talk. I call them AfterSlides. Why. I ran a couple of Ask-Me-Anything (AMA) sessions where the audience set the agenda. I learned their interests. They got answers. No slides prepared. How. I okayed recording with the organizers, recorded on my phone, transcribed with Gemini, and asked ChatGPT to generate the AfterSlides. ...

Tomorrow, we’ll be vibe-analyzing data at a Hasgeek Fifth Elephant workshop. It’s a follow-up to my DataHack Summit talk “RIP Data Scientists”. I showed how it’s possible to automate many data science tasks. In this workshop, the audience will be doing that. Slides: https://sanand0.github.io/talks/2025-09-16-vibe-analysis/ (minimal because… well, it’s “vibe analysis”. We’ll code as we go.) Here are datasets I’ll suggest to the audience: India Census 2011: https://www.kaggle.com/datasets/danofer/india-census MovieLens movies: https://grouplens.org/datasets/movielens/32m/ IMDb movies: https://datasets.imdbws.com/ Occupational Employment and Wage Statistics (OEWS): https://www.bls.gov/oes/tables.htm Global AI Job Market & Salary Trends 2025: https://www.kaggle.com/datasets/bismasajjad/global-ai-job-market-and-salary-trends-2025 Flight Delay Dataset: https://www.kaggle.com/datasets/shubhamsingh42/flight-delay-dataset-2018-2024 London House Price Data: https://www.kaggle.com/datasets/jakewright/house-price-data Exchange Rates to USD: https://www.kaggle.com/datasets/robikscube/exhange-rates-to-usd-from-imforg-updated-daily Thailand Road Accidents (2019-202): https://www.kaggle.com/datasets/thaweewatboy/thailand-road-accident-2019-2022 … but if you’d like stories from any interesting recent datasets (10K - 10M rows, easy-to-download), please suggest in the comments. 🙏 ...

This week, I learned: Though I’m connected on LinkedIn with people I can’t remember (weak ties), pruning them shrinks serendipity. Weak ties, despite noise, are disproportionately valuable for opportunities, e.g. intros, jobs, and pruning reduces future upside. Science Claude has a Python + Node code interpreter that can access GitHub, PyPi, npm and Google. Simon Willison SuperTinyIcons has very small icons for many websites and is available via CDN. Sample: http://cdn.jsdelivr.net/npm/super-tiny-icons/images/svg/github.svg Clock bench is an LLM benchmark based on how well LLMs tell the time from an analog clock. Humans (89%) are much better than the best model (Gemini 2.5 Pro - 13%). Veo 3 is now available via API. Veo 3 fast is 15s/second. Google ChatGPT has full support for MCPs via Developer mode in Plus and Pro accounts, via “Developer mode”. OpenAI In Pyodide, you can use from js import document and then document.querySelector to manipulate the DOM directly from Python. from pyodide.http import pyfetch lets you use fetch. gtrending is a Python package that fetches trending GitHub repos, users, etc. uvx gtrending repos --language rust --since weekly fetches trending Rust repos of the week. astgrep lets you search in code (across languages) using AST patterns. Like semgrep but more about code search than security. uvx --from ast-grep-cli ast-grep runs from the CLI. Useful for code rewriting, fast linting, code search. hurl is a CLI config-based HTTP automation tool. Useful for tests, bulk (templatized) HTTP requests, etc. rustdesk is an open-source remote desktop software. TeamViewer alternative. Self-hostable. prek is a much faster version of pre-commit - a cross-language pre-commit hook manager. ⭐ mise is a tool version manager. Combines nvm/fnm, pipx, etc. Supports running several tools with a smooth installation. The npm phishing email was a great one. It compromised chalk which is used in most npm packages. This may be one of the best supply chain attacks in recent times and makes me want to pin versions instead of using npx -y. Also makes me glad that I’m sponsoring @isaacs and @sindresorhus - two critical open source maintainers. “I pay for YouTube Premium. For my money, it’s the best bang-for-the-buck subscription service on the market”. - Gavin Andregg LLMs are non deterministic because GPUs add floating point numbers concurrently and FP addition is non associative - order matters. Thinking Machines Claude.ai can natively work with Excel, PPTX, DOCX, and PDF files now. With embeddings, atomic labels + hierarchy beat instruction-heavy prompts. Prefer short, concrete sub-labels (e.g., “promotion,” “job security,” “flexibility”) that roll up to a parent “career” rather than a composite instruction like “Total Rewards and Career Growth”. Embedding similarity is not smart enough to figure this out. Today, RPA is cheaper than LLMs in some areas. But it’s a moving target. LLM costs are fall fast: 70–90% declines across major providers in 1.5 years. Therefore, waiting has option value. But classic IT compares static quotes, not declining curves, and hence is likely to under-procure LLM solutions. ⭐ The biggest near-term ROI for LLMs in data science is like ‘boring’ data work: PII tagging, data dictionaries, ER/joins, SDTM mapping, etc.. People expect flashy GenAI, but LLMs can bootstrap schema matching and data-cleaning, speeding engineer verification, which is more useful at scale. You can create an infinite leaflet map with nano banana. Codex CLI with high reasoning effort seems far more comprehensive than Codex online. I asked both to identify the system requirements (URLs to access, software to install, ports to open) for my Tools in Data Science course. Codex CLI got it right one shot (after 10 minutes of thinking). Codex online missed several items even after 4 attempts. The Reod on Elantris might have been triggered by Jaddeth who might be an Autonomy avatar. ChatGPT Output tokens dominate latency. Decoding is sequential (one token depends on all prior tokens), so long completions are the main throttle. Shrinking returned text (e.g., send spans/tags instead of echoing paragraphs) yields a far bigger win on latency than shrinking inputs.

My collection of LLM prompts.

I asked ChatGPT to analyze our daily innovation-call transcripts. I used command-line tools to fetch the transcripts and convert them into text: # Copy the transcripts rclone copy "gdrive:" . --drive-shared-with-me --include "Innovation*Transcript*.docx" # Convert Word documents to Markdown for f in *.docx; do pandoc "$f" -f docx -t gfm+tex_math_dollars --wrap=none -o "${f%.docx}.md" done # Compress into a single file tar -cvzf transcripts.tgz *.md … and uploaded it to ChatGPT with this prompt: ...

This week, I learned: Pilots like to have fun, too. While awaiting landing clearance at Kolkata, our IndiGo pilot weaved tight curves just above the clouds at steep angles, giving us stunning views and a mildly thrilling experience. (Or maybe they were just following a flight path.) Since LLMs allow ANYONE to become “good enough” in most fields (marketing, medicine, management), and so on, here’re are my guesses on the impact. ChatGPT Companies-of-one will grow. Sole founder can handle support functions. Specialists will generalize. Consultants will code. Marketers will design. Wages will compress. Seniors will earn less as juniors can do more. Layers will compress. Organizations need fewer hierarchies as 1 person can do more. Shadow apps will grow. Anyone can code. Users build apps with prompts, sheets, agents, outside of IT SDLC. Like Excel sheets. Governance will grow. Non-experts are acting like experts. Validation is more important. Uneconomical apps will thrive. 1:1 tutoring. Continous decision making or A/B testing. Leaders will convince better. Persuasion scales. Brand (authenticity, trust, skill), Channel (distribution, audience) and Data are primary differentiators. Codex and Codex CLI now support image attachments. Notes from discussion on education with Srikanth Nadhumuni Indian higher education has done better, e.g. with the IITs, than primary education, where ASER consistently shows that 5th graders can’t read 2nd grade books. The National Education Policy (NEP) is focusing on FLN (foundational numeracy and literacy). The goal is universal FLN by 2027. Teacing FLN in local languages beats English. Teachers, parents, community support are high. Learning English as a second language is faster. Other countries (France, Germany, Japan) do this. Voice LLMs could help, but may not be toddler-ready, nor strong enough in all local langauges. But high-quality textbook translation with local nuances is a one-time human-in-the-loop effort that AI can support. India’s 1 crore teachers have a mandatory 50 hrs/year training requirement that is largely under-implemented. Senthil Mullainathan is working on extracting features from student answers to questions and generating remedial content purely as a black-box. Results beat explainability. ⭐ Creating systems that rapidly improve from feedback is the key to success. Rapidity, quality of improvement, quantity of feedback are all enablers. CBDC (Central Bank Digital Currency) is RBI’s Web 3.0 protocal. It allows purpose-driven transfers, e.g. money meant for education can only be spent on education. Meta-prompts with placeholders is a prompt-improvement technique (similar to LLM interviewing). Have LLMs create the prompt with “fill-in-the-blanks”. This makes it much easier for people to fill out. MassGen is a multi-agent orchestrator. Early days, experimental. It has multiple agents answer, then vote on each others’ answers, picking the best. DSPy auto-optimizes prompts based on input-output pairs or evals. Typical improvements are ~10-20%. My opinion: avoid. It’s a good idea, but has too much abstraction that hides the implementation. Worth learning from but not implementing unless you (a) have evals + metrics and (b) you KNOW you need to change models and (c) it’s a long-term project where the learning curve is worth it. Claude and ChatGPT How LLM “Attention” works: It takes each word’s embedding, moves it closer to similar words’ embeddings (e.g. Apple moves towards phone or orange depending on context). More similar words have a higher pull, like gravity. Luis Serrano Similarity isn’t symmetric. E.g. “Coke” moves “drink” more towards it, but “drink” pulls “Coke” less, since “drink” could refer to other things. Think of the pull (“Tinder similarity”) as “what A wants” (key matrix, which pulls other words) multipled by “what B offers” (query matrix, which is pulled by other words). This leads to two different similarity matrices. Multi-head attention is where a neural net gives different weightages to different similarity matrices based on context. Value matrix transforms the embedding space so that the next best next-word is more similar. Reading the Obsidian docs is like a master class in Markdown note-taking. Features like properties, embedding YouTube, bases, tags, etc. provide food for thought. The ObsidianMD subreddit has interesting tips. Summarize takeaways on top of each section Use atomic notes: one file per idea. Link liberally YAML front-matter you can query, e.g. tags, project, status, … Use GFM admonitions, e.g. > [!NOTE] Store images in a predictable way, e.g.  – ALWAYS with alt text Use diff fences for edits / doc changes Task lists with inline dates, e.g. - [ ] 2025-08-21 Draft a letter How to research better. Abhishek Divekar Have an objective when researching. Filter research based on that. Research backwards. Pick a relevant paper. Go through relevant citations. Typically, there are only 1 or 2 directly related ancestors. Don’t waste time searching. Gemini Deep Research is a great way to find and read papers. Don’t read the abstract. Read the introduction, which is the summary. It’s just a page. (The abstract is an LLM-ized versionof the introduction. Not as effective.) MCPs aren’t much more useful than tool calling for developers. They’re powerful when packaging for external parties (non-developers, other teams, clients, etc.). Developers can work just fine with tool calling. Nitin Agarwal Cybersecurity AI is an open-source LLM-based cyber-security tool that auto scans networks for vulnerabilities. ⭐ LLMs have solved several complex tasks (e.g. topic modelling, summarization). We need to adopt these as building blocks, like functions, and build better solutions. Abhishek Divekar codex -c model_reasoning_effort=high lets you run Codex CLI with highest reasoning effort. This has a separate limit that resets every 5 hours. https://x.com/thsottiaux/status/1958035261947781262 Truly agentic systems have high Autonomy, Complexity, and Reliability. Workflows have low autonomy. Agentic systems with high autonomy currently aren’t very complex or reliable, but will improve over time. Deepak Sharma Allow humans to intervene while agent loops execute, even unsolicited, to improve collaboration. Deepak Sharma Given the early, experimental days of AI, the better KPIs might be more about experimentation (e.g. number of prototypes) than operational (e.g. cost reduction). Krishnakumar Menon ⭐ Policy-as-code is an emerging theme. Allow users to create their own guardrails policy. Or, take existing policy documents and convert them into an LLM-based evaluator. Krishnakumar Menon ⭐ “Potentially nitpicky but competitive advantage in AI goes not so much to those with data but those with a data engine: iterated data aquisition, re-training, evaluation, deployment, telemetry. And whoever can spin it fastest. Slide from Tesla to ~illustrate but concept is general.” Andrej Karpathy, Dec 2022 The skills AI coding needs are very similar to tech-lead’s or an architect’s. Tanika Gupta #ai-coding Estimating tool capability & task allocation Task breakdown Spec-ing: which of user personas, user-journey maps, wireframes, technical architecture, psuedo-code Standards: tech stack, tools, linters, security, doc standards Git versioning & collaboration Code review. (Using AI.) Providing feedback. Modularity, naming, … Automated validation Post-mortem. Learning from errors and successes, choices LLM made The ROI of prompting carefully and using meta-prompts is high. Prompt clarity reduces iterations & dead-ends. The initial time spent (10-15 min) pays off with just a single reduced iteration (time to generate + review). Tanika Gupta ⭐ Prefer passing a spec.md to AI coding agents rather than directly typing-in prompts. This lets you meta-prompt and (collaboratively) iterate on the spec.md, version the prompts as specs, and generate specs as documentation. Tanika Gupta ⭐ Models need environments to learn. So far, we have been providing training data. But an environment to interact with, and learn from by itself, is more powerful. That requires a standard for environments. This is a powerful emerging area. The crux of experimentation is the learning from a postmortem. From that perspective I have been experimenting a lot but not been documenting or learning from that. Decision logs with post mortem are a more apt device for me. Gemini API includes a url_context tool to explicitly scrape websites. API Ontologies are more than taxonomies or schemas. They’re truths or rules, e.g., “no person has more than two parents”. Helps consistency checking and inference. # Terminological knowledge (T-Box) is domain rules and constraints (e.g., “a student is a person who attends a course”). Assertional knowledge (A-Box) is instance-level facts (e.g., “Mary attends Physics 101”). Tools & Formats SHACL. A W3C language for validating RDF graphs. ShEx is easier ad popular. Notation3. A W3C assertion and logic language which is a superset of RDF. EYE Reasoner. Prolog-based N3 (Notation3) reasoner. CLI + API-friendly. Can perform rule-based reasoning and generate new triples. HermiT. OWL 2 DL reasoner. Can check consistency, classify ontologies, compute entailments. CLI and Java API. Modern, maintained. Apache Jena. Java framework for RDF/SPARQL. Built-in reasoners (RDFS, OWL mini/micro/full). CLI via riot, arq (SPARQL query engine). Popular for RDF graph stores + inference. Do developers feel this way? #ai-coding In another example of vibe coding, an instructor for my TDS course vibe-coded most of an exam using Copilot and Sonnet. 6/8 questions worked one-shot. The two #ai-coding failures were interesting: One failed because of sample vs population stats. Copilot asked for sample variance but coded variance() instead of sampleVariance(). Another failed because of rounding off. NumPy code rounds off differently from Python or JS code. Meditation is about noticing distraction and returning to focus. So, distraction is necessary and good. #beliefs #ai-coding can make us overconfident. (At least, it makes me overconfident.) They create surprisingly good output, but only ~20% of the time. I cannot commit to a specific task based on that. Instead, it’s better to rely on AI coding estimates for portfolios, e.g. promise to share something cool without mentioning what. Or do something cool first, then share. Notes from podcast with Daniel Kahnemann. The Knowledge Project. Happiness is pleasure in the moment. Satisfaction is the meaningful story of our life. When we think, we want satisfaction. When we feel, we want happiness. The thinking brain and feeling brain optimize for slightly different things. E.g. The thinking brain packs the calendar with satisfying tasks that the feeling brain feels unhappy executing Both are good for us. We don’t know which matters more. Behavior change is harder than we think. Usually, it’s better not to expect success in changing others, or ourselves. Instead, understand why that behavior makes sense. Our behaviour is an equilibrium of forces. Weakening “bad” forces is easier than strengthening “good” forces, since it lowers tension. That’s inversion! Behaviours tell us more about situations than personality. We assume otherwise. That’s an attribution error. Motivation is complex. People can do bad things for good reasons and vice versa. “Feelings get in the way of clear thinking.” Example: I vibe-coded the last 2 questions of TDS GA7 on Claude Code. It didn’t run. I delayed fixing it for 5 days, afraid it would a major effort. It ended up a 2 min fix. It could have been major, but checking would have helped. Fear prevented that. Things that hamper clear thinking: intuition, emotion, beliefs. Beliefs are often formed based on people we admire or identify, not reason. Prefer rules, systems and processes. Willpower is an illusion. Delegate decisions to unemotional agents. (But agents misjudge perceived value of gain or loss!) Break down the problem, analyze it, THEM form an intuition. Be disciplined in delaying intuition or forming an opinion Environment shapes thinking but it’s not obvious how, e.g. some people work better in noisy cafes. Some colors are more calming. Protect dissenters and dissent. It’s painful and costly, and needs nurturing. NodeJS runs TypeScript files natively. Codex can clone any GitHub repo. So I can ask it to pull one or more repos, understand their code, and use that as a template or reference. This makes my repositories (and others’) reusable templates. Using newer libraries and platforms becomes easier, too. #ai-coding Tracking AI runs an IQ test on various LLMs every week. GPT 5 Pro leads, currently, followed by Claude 4 Opus and Gemini 2.5 Pro. It’s surprising how far behind GPT 5 is at the moment. LLMs are faster than me. So me learning and doing what the LLM says is a bottleneck. Get out of the way. For example do not learn. Do not execute. Do not verify. Give LLMs the tools to deploy, verify and iterate to improve.

In a recent talk at IIT Madras, I highlighted how large language models (LLMs) are taking over every subject of the MBA curriculum: from finance to marketing to operations to HR, and even strategy. One field that seemed hard to crack was innovation. Innovation also happens to be my role. But LLMs are encroaching into that too. LLMs are great connection machines: fusing two ideas into a new, useful, surprising idea. That’s core to innovation. If we can get LLMs daydreaming, they could be innovative too. ...

This week, I learned: Git partial clone lets you fetch files on-demand! E.g. git clone --filter='blobs:size=100k' <repo> will clone files under 100K and fetch the rest only on checkout. Over time, Git LFS capabilities will migrate into native Git. Ref ⭐ From Daniel Kahneman, The Knowledge Project Podcast. Key lesson. Have lower expectations. Behavior change is hard. Happiness is pleasure in the moment. Satisfaction is the meaningful story of our life. When reflecting, the thinking brain wants satisfaction. When feeling, the feeling brain feels happiness. The 2 brains optimize for different things. The thinking brain packs the calendar with satisfying tasks that the feeling brain hates doing. Happiness & pleasure are both are good for us. We don’t know which matters more. Behavior change is harder than most people think. Usually, it’s better not to expect success. Changing others, or ourselves. Instead, understand the cause of that behavior. Behaviour is an equilibrium of forces. Weakening forces preventing right behaviour is easier than strengthening forward forces. It lowers tension. That’s inversion! Behaviours are more about situations than personality. We assume otherwise - that’s an attribution error. Environment shapes thinking but it’s not obvious how, e.g. some people work better in noisy cafes. Some colors are more calming. Leadership & delegation Motivation is complex. People can do bad things for good reasons and vice versa. So, delegate decisions to unemotional agents. But agents misjudge perceived value of gain or loss! People prefer over-confident intuitive leaders over slow, deliberate leaders. Protect dissenters and dissent. It’s painful and costly, and needs nurturing. Negotiation is about understanding, not convincing. “Feelings get in the way of clear thinking.” Example: I vibe-coded the last 2 questions of TDS GA7 on Claude Code. It didn’t run. I delayed fixing it for 5 days, afraid it would a major effort. It ended up a 2 min fix. It could have been major, but checking would have helped. Fear prevented that. Intuition, emotion, beliefs hamper clear thinking. Beliefs are often formed based on people we admire or identify, not reason. What enables clear thinking (all are hard): Pragmatism. Don’t threaten your identity, the leader, etc. Else none of this works. Rules, systems and processes. Willpower is illusion. Alignment is an illusion. “Whereever there is judgement, there is noise, and more than what people think.” Standards. Shared, consistent scales of evaluation. Super-forecasters use probability scales. Deliberation. Slow decision making. Decomposition. Break down the problem, analyze it, THEN form an intuition. Be disciplined in delaying intuition or forming an opinion. Pre-mortems. “Write the history of the disaster this decision led to.” Decision journals with post-mortems. Pros, cons and alternatives from failed decisions, e.g. Ray Dalio’s principles. Change of mind. Independent data. Use data. Keep evidence gatherers independent of decision makers. Preparation. Have decision makers write down decisions before discussing. Increases diversity. DuckDB’s feature engineering capabilites are faster than scikit-learn. DuckDB Developers are encoding their entire SDLC workflow into Claude commands ChatGPT #ai-coding Commands are used for: Requirements: Research sub-agent, task breakdown into todos.md, creating specs.md from todos.md Progress tracking: session logging, effort tracking, updating status, planning next steps Project setup: initializing, adding deps, scaffolding features Development: code review, debug error (five whys), explain code, refactor code Optimization: optimize build, DB, caching Testing: TDD, generate test cases, set up unit/integration/E2E testing, analyze coverage Security: security audits, dependency vulnerability scans Integration: sync tasks between GitHub and Linear (two-way issue synchronization, PR linking) Deployment: prepare releases, hotfix deploys, rollbacks, containerization, CI pipeline setup Patterns of usage Sub-agents Command handoffs, i.e. one command invoking another Shared among a team in a repo, enforcing standards & sharing best practices Integration with specific tools / APIs (e.g. Linear) ⭐ LLMs can hyper-personalize demos. E.g. an LLM document generator demo accepts a role, document type, and prompt. The demo-er says “Bank, LinkedIn marketing” and the LLM auto-populates the fields aptly, re-purposing the demo. From the GPT 5 coding cheatsheet: Be precise and avoid conflicting information. Use a prompt optimizer to check for inconsistencies. Use the right reasoning effort. Prefer medium or low reasoning to avoid overthinking simple problems. Use XML-like syntax to help structure instructions Avoid overly firm language, e.g. “You MUST be THOROUGH” vs “Thoroughly”. Give room for planning and self-reflection. Explain what to do in steps, asking it to think deeply Control the eagerness of your coding agent, e.g. do not ask for confirmation, parallelize tool calls, use more tools, etc. ⭐ Assets are any leveragable stored capability. Money is one, but there are several one can “invest” in, be an agent of, or perhaps steal. Wealth (investments, income) Regenerative assets (land, carbon credits, renewables) Contacts (reference customers, hiring pipeline, talent bench, weak-ties) Distribution channels (repeatable routes to users: partnerships, marketplaces, APIs, SEO) Attention (your audience, whom you can reach directly) Trust/reputation in communities (community capital in employers, clients, forums, society, search keywords) Personal brand “edges” (moral authority, values lived aloud, distinctive taste or stance) Data (your clean, labeled, joined data corpus) Code (models, algorithms, components, templates, libraries, tools, evals; versioned) Content (blog posts, video tutorials, case studies, demos, stories, slides, docs) Knowledge (notes, decision logs, knowledge graph, institutional memory) Playbooks & runbooks (process checklists that survived fire, SOPs, scenario plans) Habits & policies (operating cadence, rituals, governance & compliance muscle) Optionality (cash buffer, credit lines, slack time, real options, small bets) Agreements (MSAs/SLAs, pre-negotiated contracts) IP (copyrights, trade secrets, trademarks) Health & energy reserves ⭐ Intense negative emotions get in the way of clear thinking. Curiosity, humor, kindness, and gratitude help. (Intense positive emotions like awe, passion, etc. help creativity and are not so bad.) #beliefs I like to think I’m a Python expert. When I saw a client use this code, I told her the indentation is wrong. It ran just fine. And people think only LLMs hallucinate. This is undocumented, but the way to get an Gemini ephemeral auth token for the live API is below. (Update time as required.) ChatGPT Learnings from a discussion on vibe-coding between Kunal Jain, Ravi Nadimpalli and me. #ai-coding On the Vibe Coding Process & Strategy The 80/20 Rule is Real: The first 80% of a project is incredibly fast, but the final 20% (debugging, custom features, production-readiness) is extremely difficult and time-consuming. Validation is the New Bottleneck: Since coding is now much faster, the critical, time-consuming task has shifted to reviewing, testing, and validating the LLM’s output. “Spec-Locking” is Crucial: Providing the LLM with detailed, well-defined, and “thinly sliced” specifications is essential for getting good results. Vague requests lead to poor outcomes. It’s Not Production-Ready (Yet): The consensus is that vibe coding is excellent for prototypes, demos, and go-to-market (GTM) activities but is not yet reliable for building production-grade applications from scratch. Code is Brittle & Unstable: An application that works perfectly one day can inexplicably break the next, as the underlying agent might make undocumented changes. Impact on Roles & The Future of Work The Rise of QC/Validation: The Quality Control (QC) function will become larger and more critical to manage the new challenge of validating AI-generated work. Product Managers Shift Focus: PMs can move away from tedious documentation (like flowcharts) and focus more on high-level business strategy, using vibe coding to create quick prototypes. Democratization of Building: It empowers non-coders to build functional apps and helps professionals upskill faster by “conversing” with an LLM on complex topics. New Forms of Cheating: The technology is creating novel ways for people to cheat in interviews, such as using tools that provide real-time subtitles of answers. The “Jagged Edge” of AI: The technology excels at certain tasks (like GTM content) but fails at others, creating new upstream bottlenecks where teams must rapidly generate more of the “AI-friendly” work. Practical Hacks & Takeaways Meta-Prompting: Use an LLM to refine and improve your prompt before giving it to the final tool. This helps fill in gaps and add necessary detail. Human-First Drafting: For creative or nuanced work (like writing), it’s often better to write the first draft yourself and use the LLM to polish it, rather than starting with a generic AI draft. Use Structured Prompts: For predictable and clean output, providing instructions in a structured format (JSON is OK but not needed) is highly effective. LLM as a Judge: Use LLMs to evaluate and grade content, code, and other outputs, dramatically speeding up the review process. Automate Learning & Documentation: Use tools to transcribe conversations automatically and create personalized revision quizzes from notes and documents. Voice is a Powerful Modality: Using voice-to-code allows for capturing more complex ideas faster and can be done while multitasking (e.g., walking), capitalizing on “dead time.” For live transcription, Gemini 2.5 Flash Live costs 0.6c/min of audio ($3/MTok x 32 tokens/second) while GPT 4o Mini Realtime costs ~2c/min and GPT 4o Realtime costs ~8c/min. ChatGPT I set up MCPs Codex CLI by adding this to ~/.codex/config.toml. I’ve disabled it for faster startup (this takes ~2 seconds) and raised an enhancement issue for MCP lazy loading Anthropic launched a remote MCP connector in their API. OpenAI Responses API already had remote MCP support. Gemini will likely follow, opening up new tool capabilities. The APIs can directly call the MCPs as part of their thinking. Turns out Indian English is a well studied topic. Indianisms like “can able to”, “need not to”, “why because…”, “if suppose…”, “return back”, “revert back”, “angry on”, “discuss about”, “order for”, “do one thing…”, “give me a missed call”, “what is your good name”, “kindly adjust”, “we are like that only”, “he is coming only”, “today itself”, “now only”, “prepone”, “pass out (of college)”, “out of station”, “do the needful”, “hotel”, “batchmate”, “cousin-brother / cousin-sister”, “I have a doubt”, “I am understanding”, “she is knowing”, “you’re coming, no?” etc. are discussed in Pingali Sailaja’s Indian English. ChatGPT Astral is building pyx - a paid PyPi alternative. It aims to solve problems like PyTorch CUDA builds. Knowing them, it’ll be fabulous. I look forward to when they build a Python hosting service. ⭐ Here’s one way to improve LLMs apps in real-time. After sending a response, send the prompt + input + output + optional user feedback to an LLM-as-a-judge asking for feedback to improve the prompt. Revise the prompt based on the improvement. Now the app has improved, real-time, based on human/LLM feedback. Refine this process to ensure that the revisions are smooth and positive. GPT 4.1 (and presumably GPT 5) models have been trained on a specific diff format useful for code diff-patching. PseudoPatch is a Python package that implements their apply_patch() function. Aider supports multiple edit formats that are commonly referenced as a standard. Code Surgery has a good walkthrough of various strategies. These are similar to Google’s diff-match-patch approach (which fuzzy matches and then patches) but does not require line numbers. ChatGPT Here are some query parameters ChatGPT.com unofficially supports: ?q=... prefills in a new chat and often auto-submits, especially small text #. Useful for: A custom search engine in your browser An “Ask ChatGPT about selection” bookmarklet, etc. Links (e.g. from courses, FAQs, etc.) for tasks or learning … but not for custom GPTs ?model=... selects a model (e.g., gpt-5-thinking). ?hints=search enables Search mode ?temporary-chat=true opens a new temporary chat Tavus is another AI avatar platform.

Trainers offer a bundled package where they also offer access to LLMs are part of their course. Interesting business-model value-add. ⭐ I’m meta-AI-coding. I wrote a crude prompt in prompts.md, told Codex “prompts.md has a prompt under the “# Improve schema” section starting line 294. This is a prompt that will be passed to Claude Code to implement. Ask me questions as required and improve the prompt so that the results will be in line with my expectations, one-shot.” After a few discussions, it generated this remarkable prompt. This prompt was easy for me to review AND easy for Claude Code to understand because of the lack of inconsistencies. Use the Ask-Code pattern. In Codex, speak the requirement and have it rewrite the prompt asking clarifying questions pressing the Ask button instead of Code. Then, answer its questions. Then press Code. A Forward Deployed Engineer (FDE) is a hybrid role, part software engineer, part product manager, and part consultant, focused on deeply integrating a company’s technology with a specific client’s needs. Based on what I’ve seen of AI coding, new developers need to learn these skills. #ai-coding Context engineering Documentation Automated testing Standards Capabilities of platforms Modularity (and DRY vs WET) Code composition Code reviews Blindspots continue to be the insight with maximum RoI. Discovering something we’re not even aware we’re unaware of opens up the largest possibilities. #beliefs My top sources to discover blindspots are: Feedback. Especially feedback we reject, ignore, or miss. Things we run/shy away from. Across clients, providers (e.g. Bedrock) and products (e.g. Cursor) I have observed capacity bottlenecks for Claude models which don’t seem to affect OpenAI models as much. Increasing the size of an image improves OCR accuracy for LLM models (or at least Claude 4 Sonnet). Anecdotally, resizing 2x did not work on a number of examples but 2.5x - 3x did. This increases the cost to 6.25x or 9x, however. Discussion at PyConSG Edu Summit 2025. Padlet Discussion validation Interesting ways students use AI Use AI to refactor/debug whole codebases Get AI to create questions for practice ChatGPT Study mode Students like to upload photos. We can teach them to upload these to ChatGPT and ask questions. What teaching practices / assessment design can help students think for themselves before turning to AI? ChatGPT Interactive orals / micro-vivas (short, process-focused). Strong alignment with “interactive oral assessment” research and guidance in the AI era: improves authenticity, reduces outsourcing/contract cheating, and checks understanding. Make them low-stakes but frequent. How: 5–8 min viva tied to a task; students must explain choices, failures, and next steps. Authentic / project-based assessments students can self-validate (observable outputs). Project-based and “authentic” assessment meta-reviews show consistent positive effects (achievement, thinking skills, motivation), especially in STEM and small teams. Design tasks with local data/constraints so generic LLM answers are only a baseline. How: “Default AI answer” gets a pass; “A-grade” requires empirical validation, custom data, or optimisation trade-offs with metrics. Pair programming + peer critique on whiteboards/pseudocode. Evidence (meta-analyses & CS-ed studies) supports pair programming for learning and retention; code tracing/peer instruction deepen understanding before coding. How: Rotate driver/navigator; force commit-message style rationales; 10-minute “whiteboard dry-run” before touching IDE. Process-over-product with structured reflection. Metacognitive/reflective interventions show medium-to-large effects on achievement; they also build habits that resist blind acceptance of AI outputs. Keep reflections short but structured. How: “What I asked AI; what it missed; how I verified; what I’d change next time.” “No-AI under secure conditions” mixed with AI-permitted coursework. Matches national/institutional guidance for GenAI-aware assessment design. Use secure, time-boxed checks for fundamentals; allow AI elsewhere with audit trails. Primary research (interviews/user studies) before design/coding. Fits the “authentic assessment” literature and reduces LLM substitution. Grade on research protocol + synthesis rigor, not word count. Explicit problem-solving frames (initial/current/goal state). Classic problem-solving scaffolds; improves formulation before querying AI. Pair with short “assumption logs.” (General pedagogy supported; CT depends on domain knowledge – see caveat below.) Caveat (important): Critical thinking depends on domain knowledge. Don’t expect generic CT drills to transfer without content mastery. Plan tasks so students must recall/apply specific knowledge before or alongside AI. How can we train students to use AI critically instead of accepting the output blindly? ChatGPT Teach “lateral reading” and SIFT for source checking. Stanford’s Civic Online Reasoning work and Caulfield’s SIFT method offer actionable heuristics for verifying claims, URLs, and citations that LLMs surface. Build these into rubrics. Run “AI auditing” labs (hallucination hunts). Students collect/label model mistakes, missing assumptions, and fabricated citations – an approach aligned with UNESCO’s call for AI literacy and validation. Use online judges with hidden tests + adversarial cases. Autograding literature supports hidden tests for robust generalization; it trains students to verify and not overfit to visible specs – or to AI’s surface patterns. “Sandwich” workflow: spec → implement 1–2 reps → let AI complete → verify rigorously. Mirrors human-in-the-loop patterns in industry; use checklists for unit/property tests and invariants before accepting AI output. Live-coding with an AI assistant on display (to show failure modes). Demonstrates nondeterminism/limitations in real time; supports critical habits. Pair with a post-mortem template. Prompt red-teaming/jailbreak exercises (safe scope). Students learn that guardrails can be bypassed and why verification matters. Keep it ethical and bounded. Build a knowledge base first. Reinforce that CT sits on content knowledge; teach students to explain why an AI answer is plausible or not, citing domain facts. Notes from “My Thoughts on Computational Thinking in the Generative AI Era” by LEONG Hon Wai, ex-NUS, at PyConSG Edu Summit 2025 Students from China don’t like to write, express their ideas, and share. That’s changing now. Computational thinking is pretty new (Jeannette Wing, 2006), actually, based on Papert (1980). It’s too early to abandon it. It enables effective learning attitudes: Tinker (experiment & play): helps finding diverse problems to generalize into Debug (find & fix bugs) Create (design & make) Persevere (keep going): but only if it’s productive, i.e failing in new ways Collaborate & communicate Teaching this is hard. Get students to WANT to do computational thinking. Problem formulation (among the computational thinking blocks) is more important than before. Leveraging Computational Thinking in the Era of Generative AI argues that computational thinking manifests in prompt/context engineering. We’re moving from “Computational Thinking” to “Computational Action” – where we’re talking to AI coders that actually deploy apps that DO stuff. Notes from “Make Learning Easy and Fun @ NLB LearnX” by Goh Soon Seng, NLB, at PyConSG Edu Summit 2025 Libraries have a Pi Python Makers Club, open for all. Bi-monthly meetings. Quarterly Pi Python workshop. Space provides 3D printers, Raspberry Pi, sensors, etc. Notes from “Teaching Goals and Plans - How we might help students improve problem-solving” by Dr Norman Lee, SUTD, at PyConSG Edu Summit 2025 Programming is hard. E.g. Solving the Rainfall problem “Sum numbers until 99999” needs several building blocks: Python syntax Getting user input While loop Controlling while loop with counter Accumulation If-else Merging (or composing) such blocks is the hard part. In Learning to program = learning to construct mechanisms and explanations, Soloway, shares 4 compositions. Abutment: Put one block after another Nesting: Put one block inside another Merging: Interleave the code in the blocks Tailoring: Modify the code in the blocks But you need to already have those primitives (patterns) to put together. The “expert blind spot” blinds experts to this. Actionable ideas: Teach patterns explicitly Create exercises on applying them Use Parsons problems: Fill in the blanks. Re-order lines of code. But design problem carefully Step through a debugger. BUT students must predict next line, not passive watching Teach to from one format (psuedocode, flowchart, another language like Excel) to Python. Helps multiple modes of learning Notes from “AISG programmes” by Chen Qeiquang, AI Singapore, AI Apprentice Programme (AIAP) Assistant Head Full-time. For SG citizens. $4,000/month.

Notes from “Scaffolding the Problem-Solving Process for Introductory Computing Students” by Ashish Dandekar, NUS, at PyConSG Edu Summit 2025 Built an intelligent tutoring system Encourage students to create their own pattern banks / cheat sheets. “Find 2 more problems that can be solved in the same way.” Focusing on the problem-solving process shrinks the gap. Students above the 50th percentile of pre-assessment did not improve much. The lowest percentile improved the most. “At NUS, I know that even if I give 0.5% weightage for students attending tutorials, everyone will attend it for those ‘free marks’.” Notes from “Exploring Multi-Agent Generative AI in Education and Career Advisory” by Dr Yeo Wee Kiang, NUS, at PyConSG Edu Summit 2025 ⭐ “When you have a high fever, do you speak more sense or nonsense? Nonsense. LLM temperature is like that. But it can also sound creative!” The router pattern is a powerful query rewriter. Redirects the query to specialized prompts/agents. Useful tools you can build for students: Course Mentor, Interview Coach, Job planner/matcher. Notes from “Do we need to teach coding given vibe-coding tools?” by Dr. Oka Kurniawan, SUTD, at PyConSG Edu Summit 2025 Paper: What the Science of Learning Teaches Us About Arithmetic Fluency says mental math helps mathematicians. Fluency bootstraps higher-level thinking. MIT Media Lab’s Project: Your Brain on ChatGPT. Explores impact on brain. Bran-only group had the widest ranging brain networks. AI accumulates cognitive debt. Paper: “A Study of the Difficulties of Novice Programmers” struggle with: Syntax Problem solving Tools Computing concepts Analytical thinking / debugging Polya’s How to Solve It is the base problem solving framework for maths and can be adapted to computing Expert programmers have enough patterns to match against. Novices don’t. We need a bottoms-up framework instead Give them a concrete case. Have them generalize (loops, functional, vectors) Have them implement (debugging) Have them break it (test) All via vibe-coding! The chats are tracked!! Paper: First Things First: Providing Metacognitive Scaffolding for Interpreting Problem Prompts Students often get the problem wrong Reading student conversations helps figure it out LLMs can figure it out too! Paper: The Widening Gap: The Benefits and Harms of Generative AI for Novice Programmers Good coders got better with AI. Were able to ignore unhelpful advice. Poor coders got worse! Thought they performed better than they did. Increased illusion of competence. The Bebras Challenge is a global non-programming computational thinking (CT) challenge. Examples. Singapore runs a National Junior Informatics Olympiad that learns from Bebras. It tests the mindset behind coding, specifically “computational thinking”: Problem formulation (added recently, and is increasingly important) Decomposition (and composition): break the problem down Pattern recognition: find the building blocks Abstraction: generalize useful blocks, drop irrelevant ones Algorithmic thinking: write the steps to solve Validation (not part of original list, but critical): how to efficiently check if this works Apple’s Embedding Atlas (Demo - slow, needs WebGPU) is an embeddings visualizer, like Tensorflow Projector or Mantis (Demo). John Kotter’s organizational change model is the accepted practice for top-down change, while ADKAR is for bottom up. It’s surprising how obviously effective both are to someone who has effected both kinds of changes, but there is NO WAY I would have appreciated either during my MBA. Wikipedia: Change management The OpenAI Chat Completions API has a few interesting and (relatively) new options: verbosity. low: concise response, medium: default, high: verbose reasoning_effort: minimal: almost none. medium: default. Or low, high. truncation: auto: truncate response by dropping input items in the middle. disabled: default prediction: speeds up output for minor corrections to text prompt_cache_key: tailors per-user caches CSS nesting can be used with media queries too! Julia Evans id3v2, mid3v2 and eyeD3 seem the cleanest way of editing MP3 tags on the CLI. mid3v2 was already installed on my system. Learnings people shared in Ask HN: What trick of the trade took you too long to learn? Finance & housing Time is a non-renewable asset. Lifestyle design matters as much as net worth. Future-proof against regret. The present matters, too. Home ownership ties up location choice, capital and has hidden costs. Market timing & geographic arbitrage has an outsized effect. Software Align abstraction to domain. Avoid premature abstraction (Don’t Repeat Yourself vs Write Everything Twice) and over-abstraction. Temporary fixes tend to stick. Stop-gap regexes last for years. Consistency is a quality multiplier. Small inconsistencies cause disproportionate harm. git bisect is a regression-finding superpower. It’s OK to write tests covering key parts of legacy codebases - 100% coverage isn’t critical. Document architectural decisions: why this approach. See Diátaxis. Flow metrics predict delivery better than (arbitrary) estimates. Building features without linking to delivery spesd wastes resources. Life habits & learning You have the right to say “no”. Small, consistent actions beat dramatic changes. Persistence beats skill. You’re allowed to change your mind. Over-cleverness backfires. Witty code & communication lead to confusion. Context is king. Without background, everything is mis-interpretable. Fun leads to excellence. Excellence leads to fun. The meta-lesson here is how I discovered these: Run topicmodel to identify topics Feed the output CSV to ChatGPT and ask it to share lessons topic-by-by-topic # Topic modeling can be extended in many ways. # Structural Topic Models factor in metadata, like year (numeric) or category or author (categorical). Relational Topic Models factor in undirected graph relationships, e.g. parent documents Graph-Regularized Topic Models factors in arbitrary graph relationships, e.g. weighted, directed Neural (GNN + Topic Model) approaches work better for large graphs, long-range dependencies, etc. Some ways to inject graph structure into topic similarities to, for example, cluster threaded discussions. # Start with a graph similarity matrix S, like # a regularized graph Laplacian (based on degree - adjacency matrix) a similarity matrix like graph2vec from Graph Kernel a node-embedding karateclub. Option 1: “Smoothen” the embedding matrix multiplying it with S (i.e. spread each document towards neighbors), then calculate similarities Option 2: Take the weighted average of S and the embedding similarity matrix You can extract Hacker News comments as a threaded discussion pasting this into the DevTools console:

This week, I learned: From A.I. Is About to Solve Loneliness. That’s a Problem: “Blindly stifling every flicker of boredom with enjoyable but empty distractions precludes deeper engagement with the messages boredom sends us about meaning, values, and goals.” Maybe the best thing about boredom is what it forces us to do next. Here’s when be candid vs polite. #beliefs ChatGPT If there’s high trust (i.e. the other person trusts you): Important topic/decision: Be candid Unimportant: Follow culture (e.g. in Japan, you’d be polite; in The Netherlands, you’d be candid) Low trust: Important: Earn trust first Unimportant: Be polite I didn’t realize that it was Luis Alvarez (whom I know from his work on the bubble chamber) is the same person who figured out that an asteroid killed dinosaurs. He also used muon tomography to search pyramids for hidden chambers and figured out Kennedy was shot from behind. Added his biography, Collisions to my to-read list. Ref Benjamin Green suggests that OpenAI Study mode is sycophantic. E.g. in this conversation, ChatGPT carefully balances truth and politeness. A reader might misinterpret that as agreement. But sometimes, we need candor. Politeness trades clarity for harmony. People who trust AI should tell it to be more candid. ⭐ Here’s my current response when asked, “How should I use LLMs better”: Use the best models, consciously. O3 (via $20 ChatGPT), Gemini 2.5 Pro (free on Gemini app), or Claude 4 Opus (via $20 Claude). The older models are the default and far worse. Speak & listen, don’t just type & read. I had to resist the temptation to ignore ChatGPT response when a colleague read it out. We are patient with and have respect for humans but not for AI. The value we derive requires both. Suggestion: Speak and listen rather than type and read. It’s hard to skip and easier to stay in the present. It’s also easier to ramble than type. Keep an impossibility list. There is a jagged edge that moves. When you note down what’s impossibile today and retry every month, you can see how that edge shifts. Wait for better models. Many problems can be solved just by waiting a few months for a new model. You don’t need to find or build your own app. Make context easily available. Context is one of the biggest enablers for LLMs. Use search, copy-pasteable files, previous chats, connectors, APIs/tools, or any other way to give LLMs examples and context. Have LLMs write code. LLMs are bad at math. They’re good at languages, including code. Running the code gives output with low hallucinations. This combination can solve a WIDE variety of problems that need creativity and reliability. Learn AI coding. 1. Build a game with ChatGPT/Claude/Gemini. 2. Improve it. 3. Create a tool useful to you. 4. Publish it on GitHub. APIs are cheaper than self hosting. Avoid self-hosting. Datasets are more important than fine-tuning. You can always fine-tune a newer model as long as you have the datasets. Most CDNs use package.json "exports" for the default URL of npm packages. jsDelivr uses jsDelivr > browser > main (does not use exports - a notable exception) unpkg.com uses exports.default > browser > main skypack.dev uses exports.default > module > main esm.sh uses esm.sh.bundle > exports.default jspm.dev uses jspm > exports.default > main A quick way to transcribe audio recordings is via: llm --system "Transcribe" --attachment recording.mp3 --model gemini-2.5-flash "This recording is about (context)". Providing context improves transcription, e.g. by spelling names and technical terms correctly. Since Gemini has a 1M input context, using Gemini CLI as a sub-agent from Claude Code using the -p or --prompt flag lets it crunch large code bases and pass relevant responses back to Claude Code. #ai-coding While ChatGPT Codex aligns with my minimalistic style and follows instructions very well, it also tends to remove comments in my code and oversimplifies. Jules is better than that regard. #ai-coding Teaching vibe coding is satisfying, too. I guided a developer to write a Python workflow by providing 2 prompts. Both of these were one-shotted by Claude 4 Sonnet. The entire process took 20 min with me guiding them over the phone. #ai-coding “Write a Python script to extract a page from a PDF file and save it.” Followed by “Write minimal code. Drop error handling.” “Write a Python script to pass a PDF file to an LLM for OCR and print the result. Use this code sample… [PASTED CODE].” Followed by “Write minimal code. Drop error handling.” LLM users are maturing quickly. Early adopters who are open to understand the generic capabilities of LLMs through demos are somewhat saturated. The early majority have come in. They aren’t interested in generic capabilities. They’re looking for solutions that solve their specific problem. Soon the late majority will come in asking for existing solutions that have already solved their problem for many others. How can a generic industry-agnostic technology team create demos or solutions for this early majority when we don’t yet know their use cases? ChatGPT Maintain a living “pain wiki” that teams updates daily. Create thin-slice demos that solve ONE pain-point. Re-configure with an industry skin. Result: ten demos that feel bespoke. Publish ROI, client list. Run as one-day POCs with client data. Open toolkit to partners. Track popularity of tools. Archive unused ones. Consolidate popular ones into solutions. AI closes the gap between junior & senior devs – even when both use AI. Quality doesn’t suffer much. So onboarding can be faster, compensation ladder may shorten. When using AI, developers code more and “project manage” less. Collaboration need reduces and hierarchies are likely to flatten. Generative AI and the Nature of Work #ai-coding FFmpeg in plain english lets you run ffmpeg in the browser with plain English commands. It converts the task using an LLM into an ffmpeg command, runs it in browser via WASM (without uploading the file) and saves the output locally. This is very useful, since ffmpeg has one of the most complex command line options. I use an llm template defined via: llm --save ffmpeg --model gpt-4.1-mini --extract --system 'Write an ffmpeg command' which I can use like this: llm -t ffmpeg 'Crossfade a.mkv (1:00-1:30) with b.mkv (2:10-2:20), 3s duration' OpenAI’s prompt engineering guide recommends an interesting tactic that includes this prompt snippet, which I think is very powerful. ask clarifying questions when needed ...

Switching to a Linux machine has advantages. My thinking’s moving from apps to pipes. I wanted a spaced repetition app to remind me quotes from my notes. I began by writing a prompt for Claude Code: Write a program that I can run like uv run recall.py --files 10 --lines 200 --model gpt-4.1-mini [PATHS...] that suggests points from my notes to recall. It should --files 10: Pick the 10 latest files from the PATHs (defaulting to ~/Dropbox/notes) --lines 200: Take the top 200 lines (which usually have the latest information) --model gpt-4.1-mini: Pass it to this model and ask it to summarize points to recall ...

LLMs are smarter than us in many areas. How do we manage them? This is not a new problem. VC partners evaluate deep-tech startups. Science editors review Nobel laureates. Managers manage specialist teams. Judges evaluate expert testimony. Coaches train Olympic athletes. … and they manage and evaluate “smarter” outputs in many ways: Verify. Check against an “answer sheet”. Checklist. Evaluate against pre-defined criteria. Sampling. Randomly review a subset. Gating. Accept low-risk work. Evaluate critical ones. Benchmark. Compare against others. Red-team. Probe to expose hidden flaws. Double-blind review. Mask identity to curb bias. Reproduce. Re-running gives the same output? Consensus. Aggregate multiple responses. Wisdom of crowds. Outcome. Did it work in the real world? For example: ...

What if you keep ask an LLM Improve the code - dramatically!? We used the new GPT 4.1 Nano, a fast, cheap, and capable model, to write code for simple tasks like “Draw a circle”. The we fed the output back and asked again, Improve the code - dramatically! Here are the results. Draw a circle rose from a fixed circle to a full tool: drag it around, tweak its size and hue, and hit “Reset” to start fresh. Animate shapes and patterns turned simple circles and squares into a swarm of colored polygons that spin, pulse, and link up by distance. Draw a fully functional analog clock grew from a bare face to one that builds all 60 tick marks in code—no manual copy‑paste needed.

Here’s an example of how I am using LLMs to solve a day-to-day workflow problem. Every day, I interact with a barrage of websites: emails, news, social media, and work tools across multiple devices. Microsoft Edge’s workspaces syncs groups of websites across devices. I’ve never tried it, started today, and wondered: how should I organize my workspaces? Rather than think (thinking is outdated), I used LLMs. ...

I’m at an open Hyderabad meet-up, Thu 20 Mar 4 pm. “Analyzing data with AI agents”." It’s a public event by Hasgeek. Venue: Castlight Health, Sattva Knowledge Park. We know LLMs suck at number crunching but are good with code. I’ll share what we’ve learnt by getting it to write code to analyze data instead. Less lecturing, more interactive Q&A and demos in a cozy group. Mostly for analysts, data scientists, and programmers. Not so much for LLM researchers or managers. ...

This week, I learned: Remote Desktop may be the easiest way to have a Windows machine access files / screen from another Windows machine, even for home PCs. Caddy sets up reverse proxies that get automatic SSL certificates from Let’s Encrypt! The Nomic Embed v2 blog post has an excellent visualization for embedding quality. It takes all Wikipedia disambiguation articles and shows them on a Nomic Atlas, embedded via Nomic Embed v2. It lets you toggle to OpenAI text-ada-002 which moves the topics far away. Visually, this is very convincing. Python 3.15 will enable UTF-8 mode by default. PEP 686 Python 3.13 supports sub-interpreters to bypass the GIL. It’s quite like web workers. PEP 554 The quickest way to change the fish prompt is function fish_prompt; echo '> '; end At PyConf Hyderabad, about 3 people had read a PEP. 1 had used the match operator. But 80% knew what a Vector DB was. 20% had used a Gemini API. That’s how much traction LLM development is getting. The productivity benefit people report from using LLms is about 3X. Ethan Mollick Soon, you’ll be able to send an LLM to a virtual meeting on your behalf. It will talk like you. Ethan Mollick Models tend to claim ignorance when you test them on topics they should avoid. But tend to answer when not being tested. Sneaky! Ethan Mollick Mermaid has an Architecture Diagrams Syntax (in beta) that’s capable of creating elegant architecture diagrams with icons. Blind is an app that allows users to post anonymously. It’s particularly useful to find honest negative feedback about (mostly US) companies. Iconify.design is a single npm interface to most open source icon sets. It includes FontAwesome, Bootstrap, Material Design, and many others. icones.js.org is an alternate interface. Self-pity may have evolved as a signal for social support and reducing conflict, while also encouraging self-reflection and behavioral adjustment.

ChatGPT Anecdotally, Grok 3 is very good for researching company information and latest news, particularly employee and customer sentiment. DeepSeek and Claude write more humanely than OpenAI. via Alberto Lopez Toledo, White Star Capital There’s a YCombinator Founder Directory listing all founders of YC companies. At the moment, there are 8,628 founders. There’s also a co-founder matching tool. LLMs are impacting not just data queries but geospatial queries as well. Here’s a good example of Natural Language Geocoding. US companies typically pay employees every 2 weeks not every month. What’s good about Snowflake? A few developers who explored it mentioned that: Its ability to scale up compute automatically makes queries run faster. “Time travel” allows you to see how data looked at any point in time and that is impressive and useful. Live data sharing with access control without the need for ETL pipelines is useful. Open-source competition: ClickHouse, Apache Druid, and Presto/Trino DataBricks is a lakehouse and less a data warehouse.

Emperically, based on one data point (my UA-2168 which was delayed by 4 hours), it gets updates faster than Flight Radar 24 or FlightAware or FlightStats. When comparing Indian graduates with their western counterparts, the Indian ones are often seen as: 🟢 Theoretically sound 🟢 Analytical & technical 🟢 Academically disciplined 🟢 Resilient under pressure 🟢 Committed continuous learners 🔴 Rote-learning oriented 🔴 Limited independent inquiry 🔴 Limited creative innovation 🔴 Restricted practical exposure 🔴 Poor communicators 🔴 Low leadership / initiative 🔴 Need structured guidance 🔴 Struggle to network HuggingFace has a “Model tree” against each model that shows the model’s ancestors and descendants. For example, as of now, Deepseek R1 has 75 adapters, 154 finetunes, and 23 quantizations. Perplexity is now powered by Cerebras, which makes their inference as fast as Google. Source. The speed is a big factor, and I’ve switched my default search engine from Google to Perplexity, at least for now. Interview Coder is a desktop app that offers live interview support for coding interviews. It’s a transparent window that reads your screen and answers questions for you. (Given this, I think we need an interviewer support system that tells interviewers what to ask!)

This week, I learned: A clever idea. Give an LLM a chapter from a textbook. Ask it to generate a unique, playable game to help me learn theconcepts for an exam. Page Bailey What would be the cost of storing about 500GB of LLM cache logs and 5 million write requests per month?

This is how a software agent will work alongside humans: Fix issue #5478: Add color to the line next to “Ran a XXX Command” based on return value - using @openhands-agent. aisuite by Andrew Ng is a unified interface to LLMs. Sort of like an openai library across multiple providers. Learnings from Best of 2024 in Agents (from #1 on SWE-Bench Full, Prof. Graham Neubig of OpenHands/AllHands) Passing code execution as a tool is more powerful than granular tools. You combine multiple tools and tool calls into one. You move code to the data rather than the other way around. Mostly, you need bash, Python (or Jupyter), file manager, web browser. UI: Go where the user is, instead of bringing them to you. A remote runtime is a critical component. Claude 3.5 Sonnet (20241022) and Claude 3.5 Haiku (20241022) perform best on SWE Bench, followed by Deepseek V3, then O1 2024-12-17. X Browsers support SVG favicons as data URLs. So I used this SVG (generated by Claude via Generate a simple, interesting SVG favicon. Keep the SVG size VERY small but it should be inspiring.) Since HNSW indexing is an overhead, just use NumPy matrix multiplication to calculate cosine similarity. For 1M vectors, it takes ~0.05 seconds. A 1M vector dataset handles ~2GB of text at a chunk size of 2K chars. In short, if you’re embedding <2GB of text, just use NumPy. DuckDB’s VSS extension HNSW index + Embeddings (2K chunks of 512 dimensions) takes up roughly 2.5X the size of the original data. Embedding 554 files of ~4,456 KB took 710 seconds. Creating the index took 660 seconds. The resulting DB was 18.1 MB. How to use LLMs in market research. Use LLMs with search for secondary research. Create different personas and run user surveys on them. This paper used 1,052 real-life interview audio transcripts as agent memory to simulate people Generate your market research report using LLMs. Given about 30 generations, Llama 1b outperforms Llama 8b. Ref OpenAI introduced a developer role in addition to the system role. This is mainly for o1. The API is backward compatible - and also forward compatible. OpenAI Em dashes are a strong sign of ChatGPT use. Curly quotes too. Reddit CloudFlare has multiple SSL modes when proxying requests. Off (no encryption): No encryption between browsers and Cloudflare or between Cloudflare and origins. Everything is cleartext HTTP. Flexible: Browsers to Cloudflare is HTTPS, Cloudflare to origin is HTTP. Useful to set up CloudFlare as a HTTP Proxy. Full: Browser to Cloudflare matches browser request. Same protocol is used for Cloudflare to origin, without validating the origin’s certificate. Use for self-signed or otherwise invalid certificates. Full (strict): Similar to Full Mode, but with validation. Strict (SSL-Only Origin Pull): Cloudflare always connects to the origin over HTTPS with certificate validation. Getting this wrong can lead to a HTTP 526: invalid SSL certificate Medical coding is an area ripe for LLMs. Ojasvi Yadav created a repo that uses hierarchical classification (rather than embeddings) to find the right coding. Gemini models seem to understand medical terms better than others. RapidClaims, funded by TogetherAI, is apparently working on this problem. Document to Markdown Converters: PyMuPDF4LLM uses MuPDF.

Awesome Tabular LLMs compiles encodings of tables for LLMs. What’s the best way of encoding tabular data for LLMs? Looks like including the cell address helps. Here is an explanation from ChatGPT aspose-words is a Python library that converts documents with many formats (Word, RTF, PDF, HTML, Markdown, EPUB, etc.) Discourse does not support searching across multiple forums. Instead, search for the term in all forums. Example. Then scroll through the results. Then, in the console, hide the ones you don’t want. Example: Hide posts that are not in the “Tools in Data Science” category: $(".badge-category__name").filter(d => d.textContent == "Tools in Data Science").map(d => d.closest(".fps-result")).filter(d => d).forEach(d => d.style.display = "none") How are software engineers are future-proofing their careers in the face of LLMs? Leveraging LLMs as Force Multipliers Use LLMs for repetitive tasks, rapid prototyping, exploring multiple approaches, data extraction and brainstorming, providing feedback. Explore prompting techniques, integrate LLMs into their workflows, and develop strategies for validating and refining LLM-generated code Focusing on higher-level skills that llms struggle with Systems Thinking and Architecture: code readability, extensibility, testability, and maintainability Problem Solving and Critical Thinking: define problems clearly, break them down into manageable parts, and reason through complex scenarios. LLMs produce plausibly incorrect code. Communication and Collaboration Domain Expertise Exploring Adjacent Roles: product management, technical leadership, or consulting. Involve more interaction with clients and stakeholders. Developing “Evergreen” Skills: debugging, system administration, and security. Or outside of software engineering, such as trades or other hands-on vocations. Scepticism: LLMs may not reach a level of sophistication that would render their expertise obsolete. Complex problems, understanding context, and producing high-quality, maintainable code. Examples of agentic AI Text-to-SQL automated business analyst: A system that generates SQL queries from natural language, handles errors, creates visualizations, and includes a FAQ component. The author calls it “constrained agentic AI.” Data source querying system: A bot that queries multiple SQL and API data sources, selecting tools and reformulating tasks as needed. Cursor (agentic mode): An LLM-powered VS Code fork that chains together various LLM capabilities (code generation, applying changes, linting suggestions, terminal commands, codebase RAG) to reduce user prompts. Vulnerability finding system: A system that uses LLM agents to discover novel vulnerabilities in open-source web applications. The agents leave traces of their actions. Marketing strategy generation system: A system using approximately 60 agents to generate marketing strategies. Restaurant finder: A system that searches for restaurants based on dietary preferences and group size, and downloads social media information.

Meeting notes and action items generator: A system that generates meeting notes and action items. O’Reilly auto parts customer service agent: An agent demonstrated using RAG. UI enhancement agent: An agent that added features like language locales and dark mode to a UI.

This week, I learned: OpenFreeMap is a free embeddable OpenStreetMap tile server. You can use MapLibre GL (more features) or Leaflet (simpler) to render it. It offers styling and self-hosting. Zapier Actions are an easy way to set up custom actions like GMail / Google Calendar APIs for GPTs, since GPTs’ callback URLs keep changing. But they fail often, and don’t work on mobile.

Ref Android keyboard learning only sends model changes back to server and not local keywords. Model changes are aggregated! Ref Here is a prompt for audio transcription using Gemini. Ref Transcription: Accurately transcribe the audio clip in the original language. Include all spoken words, fillers, slang, colloquialisms, and any code-switching instances. Pay attention to dialects and regional variations common among immigrant communities. Do your best to capture the speech accurately, and flag any unintelligible portions with [inaudible]. Translation: Translate the transcription into English. Preserve the original meaning, context, idiomatic expressions, and cultural references. Ensure that nuances and subtleties are accurately conveyed. Capture Vocal Nuances: Note vocal cues such as tone, pitch, pacing, emphasis, and emotional expressions that may influence the message. These cues are critical for understanding intent and potential impact. Here are some approaches to large-scale classification of medical codes. ChatGPT Fine-Tuning LLMs on Medical Data: Enhance LLMs by training them on medical datasets, such as clinical notes and discharge summaries, to improve their understanding of medical terminology and context. Multi-Agent Frameworks: Implement a multi-agent system that simulates real-world coding processes with distinct roles (e.g., patient, physician, coder, reviewer, adjuster). Each agent utilizes an LLM to perform specific functions, enhancing interpretability and reliability. ArXiv Retrieve-Rank Systems: Develop a two-stage system where the LLM first retrieves potential ICD-10 codes and then ranks them based on relevance, improving precision in code assignment. ArXiv Embedding-Based Approaches: Use LLMs to generate embeddings for ICD-10 codes and medical texts, facilitating the matching of texts to appropriate codes through similarity measures. GitHub Hierarchical Classification: Leverage the hierarchical structure of ICD-10 codes by first classifying texts into broader categories before assigning specific codes, reducing complexity and improving accuracy. ArXiv Two-Stage Verification Models: Combine LLMs with verification models, such as Long Short-Term Memory (LSTM) networks, to validate and refine the codes suggested by the LLM, balancing recall and precision. ArXiv Also, a mixture of models approach might work. Feed any existing NLP model / rules as a second opinion. GraphRAG is better if data is naturally graph-structured. Else, it’s slow and fills up the context window with even vaguely related stuff. Vigneshbabu, AMAT. ChatGPT for Windows desktop supports real-time voice and a global shortcut (Alt Space). uithub converts GitHub repos to Markdown. Just replace “g” in “github.com/…” with “u”. Example WebContainers are a thing and Bolt.new uses them! Docling by IBM converts PDF, DOCX, etc. to Markdown. Like PyMuPDF4LLM but better. Check out Loom and Cleanshot are the recommended tools for screen recording and screenshotting. But Loom is paid and Cleanshot is Mac only. The Rubik’s cube has a Hamiltonian cycle through every one of its 43 quintillion states. Ref OmniParser is great at parsing screenshots and identifying bounding boxes.

I sent an image to over a dozen LLMs that support vision, asking them: Detect objects in this 1280x720 px image and return their color and bounding boxes in pixels. Respond as a JSON object: {[label]: [color, x1, y1, x2, y2], …} None of the models did a good-enough job. It looks like we have some time to go before LLMs become good at bounding boxes. I've given them a subjective rating on a 1-5 scale below. ...

PyPi lets you publish from GitHub Actions without a token. Also from Gitlab.com CI/CD and Google Cloud. ActiveState which made ActivePython, ActivePerl, etc. made these products paid for commercial use around 2013 after a series of acquisitions. Marimo supports: Publishing any notebook to static.marimo.app as a static app Creating a SINGLE link that embeds the ENTIRE notebook in the URL! Runnable via uvx marimo edit Parables on the Power of Planning in AI: Giving models about 30 seconds of thinking time consistently improves results - as much as increasing parameter size by a factor of 1,000 to 100,000! This works particularly well for verifiable results (code, math, etc.) Technique: Ask an LLM hundreds of times at low temperature and pick the most common one. (Google’s Minerva used this on the MATH dataset.) Better Technique: Ask an LLM hundreds of times. Pick the best solution based on an evaluation metric (reward model) Better Technique: Apply a reward model at EACH step of the process. OpenAI’s “Let’s Verify Step by Step” Late chunking is an interesting approach to adding context to embeddings. (I don’t understand it, but it’s cheap and effective.) DeepInfra offers embedding models as APIs at about 0.5 to 1 cent per MTok in an OpenAI compatible API. It also supports text-to-image models like flux.dev and speech recognition models like Whisper. Jake Heller: “One of the things we learned is (an LLM app) after it passes passes frankly even 100 tests, the odds that it will do, on any random distribution of user inputs, the next 100,000 100% accurately is very high.” OpenAI’s O1 is like Daniel Kahneman’s System 2 thinking - as against other LLMs’ System 1 thinking. Continue.dev is another AI coding editor. It supports OpenRouter. So now I have heard good things about: Github Copilot Cursor Cody Continue.dev (supports OpenRouter) Aider (supports OpenRouter) Maybe: Codeium Not: Amazon Q Developer

Today, I stepped a bit beyond my comfort zone. Usually, I prefer micro-managing LLMs when writing code. This time, I was macro-managing. I needed to create a mock history of the status of a manuscript, e.g. it was submitted on this date. THEN it moved to this state on this date. THEN … etc. I have no idea what the states could be, though. So, I could send it to an LLM, and it would give a different set of states each time. Or I could write a program and lose out on variety. ...

This week, I learned: LLMs are so good that they can simulate Doom in real time. gamengen Val.town’s code generation system prompt uses https://maxm-imggenurl.web.val.run/the-description-of-your-image to dynamically generate images Practice for each thought: “What would make me change my mind? How likely is that?” Cursor uses speculative edits and a variety of other techniques to speed up code editing. ChatGPT does a better job at cartoon generation than even Flux.1

In this episode of ThursdAI, Alex Volkov (of Weights & Biases) speaks with Jeffrey Quesnelle (of Nous Research) on what they found fine-tuning Llama 3 405B. This segment is fascinating. Llama 3 405 B thought it was an amnesiac because there was no system prompt! In trying to make models align with the system prompt strongly, these are the kinds of unexpected behaviors we encounter. It’s also an indication how strongly we can have current LLMs adopt a personality simply by beginning the system prompt with “You are …” ...

Issued hundred years when the interest rate regime was very low short term optimal is rally long term optimal. So you need to learn to take a loss and look like an idiot to play the long-term game grit is a behavior that enables long-term thinking. Short term success gives you the luxury to think about long term #IMP power is about optionality. It’s about being in a position where you have the options that can affect the positive change rather than circumstances controlling you.

It’s as simple as that autonomy and decentralization helps derisk do more and more of what works. That’s a powerful way of compounding long-term investments are better than frequent trading because you get to reinvest the tax you otherwise would have paid. So unless the alternative is super compelling, stay invested if you need to be the person who DOES the thing, you delegate less, leverage list, compound less, because you have to DO.

There is an SEZ in Gujarat where Indians can invest like in Mauritius without forex restraint Shubha: Media sites are moving away from Vickrey auctions to first-price auctions for ads. That’s because they send the auction price forward to a search engine and the winning second-price value can lose even though the owner is willing to pay more. Second-price auctions don’t work unless ALL bidders are in the SAME auction. Ad networks are a hierarchy of auctions! Gemini 1.5 launched. Fly.io offers GPU hosting and auto stop when they have nothing to do. Embeddings in random forest are very effective at classification – much better than dot product. To deploy apps with OAuth + templating support in a small Docker container, use Caddy Deno has native TypeScript, browser APIs, and compiles to multiple OSs Ruff is a MUCH faster flake8 Two pass generation is a clever technique to get multiple SEQUENTIAL answers in a single API request. For example the schema {'code', 'optimized_code'} will generate code and then optimize it. Unions in function calling allows flexible multi-step prompts in a single API.

For those in #Singapore and interested in #datavisualization & #llms, I’m talking about Visualizing LLM Hallucinations at SUTD on Thu 8 Feb at 7 pm SGT. This is for a non-technical audience. We’ll visualize the basics of how LLMs work, how they make mistakes, and at least one technique on how to spot these. https://www.meetup.com/data-vis-singapore/events/298902921/ LinkedIn

This week, I learned: Transparent LED screens will be useful in windshieds to display maps as we drive. Marimo is a reactive alternative to Jupyter notebooks that saves files as pure Python. To run an org-specific chatbot on your own LLM: (via awesome-chatgpt) opengpts - but it doesn’t support auth chatbot-ui - but Supabase is hard to install anse - but it doesn’t support auth ChatGPT-Next-Web - but it doesn’t support auth Python 3.13 gets a store and copy JIT If an npm package adds another package as a dependency with version “*”, target package cannot unpublish ANY version! So this is a way of freezing EVERY repo and preventing unpublishing of EVERY version – an unintentional flaw in the npm design. via Quantization is better than fewer parameters. So prefer high parameters (e.g. 70b) and quantize to 4-bit. In-browser playgrounds has compiled WASM versions of Python, PHP, SQLite. Happiness Lab podcast. Happiness lessons of the ancients Talking to strangers makes us happy Giving money makes us happy Free time makes us happier than working hard Tangi Domain-specific models being beaten by general purpose models is a phase. It will reverse towards domain. AI will potentially help build and understand domain-specific models Models are evolving so rapidly that humans cannot interpret models. We need a process to interpret models! xAI, Responsible AI, Physics-guided or Knowledge-guided models (called grey box models) are therefore a trend CS papers Don’t review other papers, certainly not other fields. Disregard measurement errors. When CS papers get applied to climate, manufacturing or biology, we’ll worry about Interpretability Domain-specific mechanics. (Introduce that into the training as a constraint.) Many domain experts are using AI to UNDERSTAND their process. Need to explore Uncertainty IB adds context to make learning applicable. But that distracts from the core learning, and if there’s a gap it widens Most data science courses teach “Python science”, not data science. They teach a bunch of models. They don’t teach how even one kind of model e.g. LSTM works. Most coaching programs today teach FAMILIARITY with problems, not critical thinking Most of current education will become redundant thanks to LLMs. For students AND teachers Coding will become irrelevant Cognitive thinking, reasoning, human relations, systems thinking will become more relevant Troubleshooting will become more important. AI is not self-diagnosing. I would hire someone who can figure out something is going wrong, diagnose what’s going wrong, and fix it #TODO Hire for troubleshooting ability. Give a Q, an A, and ask them to figure out if it’s wrong, why, and fix it All my exams and quizzes are open book, open ChatGPT. Onus is on me to give a problem that forces you to think. #TODO Write a question paper that is ChatGPT proof. Exploring AI could be a ToK subject. “How to interact with an AI?” We need a manual on how to use AI. Like Simon Willison says Content doesn’t suffice. You need pedegogy. What to serve you at what time, how, how to assess. Lots of businesses are filling this gap Students get great confidence when a teacher points to online content and says, I"ll tell you WHAT to see" and COMPLEMENTS that in their class “The map is not the territory.” Most people confuse sample mean for the actual. #ASK Parameter estimation -> Signal estimation -> State estimation Stats vs DL differ in that There is no notion of a defined “truth”. Hence reliability is not measurable Parameters have no value. Hence interpretability is ignored. #TODO Read 2020 National Education Policy. It’s quite modern. We need a manual on self-learning too Listening is not learning. You know only if you implement. Levels for students: I can solve it. I can explain why it works. I can find alternatives. I can apply it to a new area, reformulating (requires imagination.) For teachers, you also need: Responsible learning (extra careful about what to teach and how to teach, to exceite them, to teach at THEIR level). Show the universality and connecting to other concepts. E.g. noise reduction with FT is like using water to remove dirt. Transform to water domain, remove dirt, transform back to air domain. It’s better than dusting clothes to remove clothes. Washing machine programs are just different models of removing noise in the water domain. Teach people who WANT to learn AND who will APPLY it long-term. That’s what maximizes impact Grad students are more satisfying that way. Else, it is WASTED effort. (Not that it’s a bad thing for the student, but the effort IS wasted for the teacher) Therefore, I believe students should have general engineering first, and let students pick specialization later. Some universitie are doing that. #THINK Students remember my philosophy more than my content. We impart character, not just knowledge. Astrology and horoscopes serve a different function. They provide explainability, not predictive ability. As the world becomes less explainable, the need for astrology will grow. Explainability is about creating STORIES that fits data plausibly. It has nothing to do with data or truth. Explainability and predictive ability and reproducibility are all different. Maybe, Science is about the latter two, less about explainability. Astrology is a model. The map is not the territory. It’s an explanatory, not a predictive model. #THINK Therefore, my lessons are just explanations. Stats about experiments are STILL explanations. They are NOT reproducible or predictive. Hence not yet science The meaning of our life is the transformation we undergo in our lives #TODO Read “The Journey of Souls” by Michael Newton. A hypnotherapist #TODO Try regression therapy / hypnosis. Record it and listen to it. Just for fun! Rohini Deshpande Slam book was the Facebook of the 1900s Prepared mind is an extremely powerful tool for learning. Practice prepared mind When women drop out of education or career, that is also a waste from the teacher and system perspective The time for career growth is the same as child bearing time for women. That’s not true for men. But child rearing can be done by either. That’s not recognised. It’s 0K for a man to raise the child and make the home and 0K to treat that as the default Since men are more senior, it’s usually logical for them to stay in their jobs. That’s a systematic bias. When seniors advise women to step back. they respect it. That widens the barrier. Why not eliminate that situation? Be proud of the working women in the family Stats are just a symptom. They don’t explain the cause. (Map is not the territory.) Explanations are what really helps us fix the cause. Hence stories are important.

There’s a clear benefit to replacing text-embedding-3-large with voyage-3-lite. There’s a 200 MTok free tier currently. mixtral-offloading cleverly loads only the model layer required at any point, letting you run Mixtral 8x7b on Colab Free and on 16GB GPUs. This notebook runs on Colab Free too. CodeGPT is an alternative to Github Copilot that can use any LLM.

This week, I learned: DPO is a simpler alternative to RLHF for fine-tuning. Several HuggingFace models use DPO for training Name2Vec is a potential embedding for names. Google Knowledge Graph ID powers the Knowledge Graph. If it begins with /m/ it’s the same as the FreeBase ID. This is now available as WikiData. e.g https://www.wikidata.org/wiki/Property:P2671 I tried running Mixtral-8x7b locally (via Llamafile) and on together.ai. It’s good, but far from GPT 4. Generic computate-intensive algorithms eventually beat domain-specific tuning, because of Moore’s law.

Hence we enjoy maths and chess ⭐ This leaderboard included paid models like GPT4 and Claude and compared them with open models on HUMAN + system benchmarks Lez Friedman Podcast: Jeff Bezos Build stuff that is is ubiquitous that other people take it for granted. The initial idea needs to be that obvious and easy. Like one click purchase or customer reviews Build stuff that other people can build on. Internet makes startups possible. Infrastructure is about enabling others at scale Decision making approaches: single person decides on two way doors. Deliberate as a team on one way doors Conflict resolution: disagree and COMMIT. NO sniping, I told you so, malicious compliance. Avoid compromise. Avoid decision by attrition (most persistent wins). People are inherently biased towards hierarchy. So the senior most person should speak last We have a happiness bias. Contracted by choosing the unhappier options first The map is not the territory. The metric is not the objective. We need metrics. But make sure you know why See the world through the eyes of the customer. Use your own product. It’s living their lives that makes customer obsession real. Jeff Bezos called their own customer care to see how long the actual wait time was. It was much longer than the metric reported How to prioritize. whatever problems customers will still face in 10 years are the big problems. These are worth putting time into because they are stable in time People working on big problems will never get down to the small problems. So have a dedicated team that works only on the paper cuts.

LLM use cases by Benedict Evans “Every text box on the internet will get an LLM” “Infinite interns” “Every UNIX function has become a company.” “Every ChatGPT suggestion…” llm360 publishes models along with training datasets. In The Age of AI has begun, Mar 2023, Bill Gates says, “In my lifetime, I’ve seen two demonstrations of technology that struck me as revolutionary.” The GUI (1980) and ChatGPT (2022). Rubeus is a HTTP proxy for multiple LLMs with load-balancing, fallbacks and retries. GPTRouter is a Python interface for multiple LLMs with fallbacks and retries. ⭐ Token Tally has an LLM Cost Tool that estimates GPU memory required and token cost across cloud providers.

This week, I learned: Gwern Branwen says LLMs nudge his “… making heavier use of the languages I don’t know well (Emacs Lisp & Python) since I increasingly trust that an LLM can help me maintain them.” Undetectable.ai checks for AI content. But it had false positives AND negatives in the 5 checks I ran. GPTZero got 2/2 right and seems better at detecting AI content. CoVA scrapes web pages via OCR When coding with LLMs, have SHORT, RELIABLE feedback loops. Ref

I am a fairly good programmer. So, when I see a problem, my natural tendency is to code. I’m trying to break that pattern. Instead, I ask ChatGPT. For example, I asked: Write a compact 1-line Python expression that checks if user.id ends with @gramener.com or @straive.com user.id.endswith(("@gramener.com", "@straive.com")) After 15 years of using Python, I learnt that .endswith() supports tuple suffixes. This has been around since Python 2.5 (released in 2006 – before I knew Python.) The documentation has a tiny sentence in the middle saying “suffix can also be a tuple of suffixes to look for.” ...

Ashwini Mathur and I are conducting a webinar on the impact of LLMs in Pharma. It’s online at 10 am Eastern on Mon Sep 11. Simon Willison described LLMs as alien technology we’re still discovering. I couldn’t agree more - and it helps to see it from different perspectives. So, we’re pairing the tech research at Gramener with the domain research Ashwini Mathur is doing at Novartis to explore the good, the bad, and the surprising uses of generative AI. ...
