Here’s a comic book analyzing my Google Search History. It’s a simpler version of my earlier post. I created it using PicBook, a tool I vibe-coded over ~5 hours. PicBook: https://tools.s-anand.net/picbook/ Code: https://github.com/sanand0/tools/tree/main/picbook Codex chat: https://chatgpt.com/s/cd_6886699abfb08191acf036f6185781be The code prompt begins with Implement a /picbook tool to create a sequence of visually consistent images from multiline captions using the gpt-image-𝟭 OpenAI model and continues for 6 chats totaling ~22 min. My review took 4.5 hours. Clearly I need to optimize reviews. ...

For those curious about my Vipassana meditation experience, here’s the summary. I attended a 10-day Vipassana meditation center. Each day had 12 hours of meditation, 7 hours sleep, 3 hours rest, and 2 hours to eat. You live like a monk. It’s a hostel life. The food is basic. You wash utensils and your room. There are rules. No phone, laptop, no communication. You can’t speak to anyone. As an introvert, I enjoyed this! You can’t kill. Sparing cockroaches and mosquitos were hard. You can’t mix meditations. But I continued daily Yoga. You can’t steal. But I did smuggle a peanut chikki out. No intoxicants or sexual misconducts. ...

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 ...

I’m off for a 10-day Vipassana meditation program. WHAT? A 10-day residential meditation. No phone, laptop, or speaking. https://www.dhamma.org/ WHEN? From today until next Sunday (13 July) WHERE? Near Chennai. https://maps.app.goo.gl/PnGkLoZ8U6aG2RKk8 WHY? I’ve heard good things and am curious. SURE? I’ve never been away from tech for this long. Let’s see! I’ve scheduled LinkedIn posts, so you’ll still see stuff. But I won’t be replying. LinkedIn

If someone asked me, “What’s changed this year in LLMs”, here’s my list:" Prompt engineering is out.

LLMs can’t yet create good sketch notes. LLMs still draw bounding boxes as well as specialized models. Agents (LLMs running tools in a loop) can think only for ~6 min. What’s on your list of things LLMs still can’t do? ...

LLMs are smarter than us in many areas. How do we control them? It’s 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. Ask many. Wisdom of crowds. Outcome. Did it work in the real world? For example, you can apply them to: ...

My VizChitra talk on Data Design by Dialog was on LLMs helping in every stage of data storytelling. Main takeaways: After open data, LLMs may the single biggest act of data democratization. https://youtu.be/hPH5_ulHtno?t=01m24s LLMs can help in every step of the (data) value chain. https://youtu.be/hPH5_ulHtno?t=00m47s LLMs are bad with numbers. Have them write code instead. https://youtu.be/hPH5_ulHtno?t=06m33s Don’t confuse it. Just ask it again. https://youtu.be/hPH5_ulHtno?t=05m30s If it doesn’t work, throw it away and redo it. https://youtu.be/hPH5_ulHtno?t=20m02s Keep an impossibility list. Revisit it whenever a new model drops. https://youtu.be/hPH5_ulHtno?t=20m02s Never ask for just one output from an LLM.

How long have you made ChatGPT think? My highest was 6m 50s, with the question: Here are vehicle telematics stats for 2 months. Unzip it and take a look. Find interesting insights from this data. Look hard until you find at least 5 surprising insights from this. The next largest thinking block (5m 42s) was where I asked: I would like to explore parallels to the current phenomenon where intelligence is becoming too cheap to meter. Historically, both in recent history as well as over ancient history, what technologies have made what kind of tasks so cheap that they are too cheap to meter? Give me a wide range of examples ...

Jason Clarke’s Import AI 414 shares a Tech Tale about a game called “Go Think”: … we’d take turns asking questions and then we’d see how long the machine had to think for and whoever asked the question that took the longest won. I prompted Claude Code to write a library for this. (Cost: $2.30). (FYI, this takes 2.3 seconds in NodeJS and 4.2 seconds in Python. A clear gap for JSON parsing.) ...

Here’s how I use ChatGPT, based on the ~6,000 conversations I’ve had in 2 years. My top use, by far, is for technology. “Modern JavaScript Coding” and “Python Coding Questions” are ~30% of my queries. There’s a long list with Markdown, GitLab, GitHub, Shell, D3, Auth, JSON, CSS, DuckDB, SQLite, Pandas, FFMPeg, etc. featured prominently. Next is to brainstorm AI use: “AI Panel Discussions”, “AI Trends and Business Impact”, “LLM Applications and DSLs”, “Industry Use Cases and Metrics” are also fast growing categories. I brainstorm talk outlines, refine slide deck narratives, and plan business ideas. ...

WHY: I want to learn new uses for LLMs and share what I know. WHO: I’ll contact you based on what you’d like to discuss. WHERE: Google Meet. I’ll share an invite when mutually convenient. ...

I use Codex and Jules to code while I walk. I’ve merged several PRs without careful review. This added technical debt. This weekend, I spent four hours fixing the AI generated tests and code. What mistakes did it make? Inconsistency. It flips between execCommand("copy") and clipboard.writeText(). It wavers on timeouts (50 ms vs 100 ms). It doesn’t always run/fix test cases. Missed edge cases. I switched <div> to <form>. My earlier code didn’t have a type="button", so clicks reloaded the page. It missed that. It also left scripts as plain <script> instead of <script type="module"> which was required. ...

ChatGPT’s pretty useful in daily life. Here are my chats from the few hours. At the dry fruits store. https://chatgpt.com/share/68578741-72cc-800c-bcd0-de176a3a54db Can I eat these raw as-is? Can I bite them? Are they soft or hard? How hard? ANS: Dried lotus seeds are too hard to eat raw. Suggest snacks in India, healthy, not sweet, vegetarian, bad taste so I don’t binge, dry not sticky. ANS: Seeds. Fenugreek, flax, sunflower, pumpkin, … ...

Software companies build “SaaS”-like apps today. Agents will replace apps. Instead of UI, workflows, and app logic, they’ll engineer prompts, APIs, and evals. " But apps need domain and code. LLMs are crushing the coding workload. This lowers cost of development, increasing ROI (so there’ll hopefully be more demand). So, will domain matter more? It might seem so. But most actually people use LLMs more as a domain expert than a coder. ...
