Things I Learned - 06 Jul 2025

This week, I learned:

• When adding a coding benchmark for LLMs, here’s a question I’d like to add. #benchmark

  How do I use Apache Arrow in the browser via cdn.jsdelivr.net to create a .parquet file and download it? Give me minimal working code I can paste in the browser console to test.

• LinkedIn has an undocumented link that shows schedules posts at https://www.linkedin.com/share/management/ which redirects to https://www.linkedin.com/feed/?shareActive=true&view=management
• Here’s a JS snippet you can paste in the DevTools console of an npm package version page (example) to get a Markdown list showing the versions and dates

  copy(
    $$('table[aria-labelledby="version-history"] tbody tr')
      .map((tr) => {
        const a = tr.querySelector("a");
        const date = new Date(tr.querySelector("time").getAttribute("datetime")).toLocaleDateString("en-GB", {
          day: "numeric",
          month: "short",
          year: "numeric",
        });
        return `- [${a.textContent.trim()}](https://npmjs.com${a.getAttribute("href")}): ${date}.`;
      })
      .join("\n"),
  );
