Manuel Chakravarty writes Just Testing, a personal blog at justtesting.org about programming and systems. Since 2009, 8 different Hacker News readers have linked it 14 times. It is still writing: the last post was on 2026-09-25, and you can follow it by feed.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
Commenters link Manuel Chakravarty's posts on the thinking behind Haskell for Mac playgrounds, the Repa array research behind the Blaze NumPy design, and whether programming languages are languages.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Welcome to the blog of Manuel M T Chakravarty!

HN discussiona lot of the design ideas are pulled from some great research http://justtesting.org/repa-3-more-control-over-array-repres... (that paper is the most current relevant one, though theres a few others). chatted with stephen about Repa and hpc code engineering the evening before the talk, its all haskell ideas ported to python land under the covers :) (as the slide deck admits!)

HN discussionhttps://justtesting.org/post/70871612766/lets-program Small children learn two languages because they're surrounded by people speaking two languages. Children's brains are highly plastic; if they were immersed in people speaking code language as they speak natural language constantly, then they would learn that, too.
