labs.quansight.org is the company blog at labs.quansight.org, writing about programming and data. Since 2019, 32 different Hacker News readers have linked it 61 times, most often “Why SciPy builds for Python 3.12 on Windows are a minor miracle”. No feed was found, so read it on the site itself.
Too few sampled comments (9) to say how often HN recommends it.?
Why HN links it
HN readers link Quansight Labs posts on building SciPy for Python 3.12 on Windows, pyflyby for REPL imports, IPython 8.0 lessons and the free-threaded GC in CPython. One commenter named the SciPy post a favourite of 2023.
Summarised by Claude from a sample of 9 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
Not OP but the ability to natively implement complex groupby logic is a huge plus for me at least. Say you want to take an aggergation like "the mean of all values over the 75th percentile" algonside a few other aggregations. In pandas, this means you're gonna be in for a bunch of hoops and messing around with stuff because you can't express it via the api. Polars' api lets you express this directly without having t…

HN discussionGreat write up! A small typo here (in the companion blog post https://labs.quansight.org/blog/2022/01/ipython-8.0-lessons-... ) I think: > Python has multiline strings with triple backticks I think this should say "quote marks" instead of "backticks" since backticks are a different char, Python strings use single- or double-quote char, and three of them delimits a multiline string.

HN discussionI think the motivation there historically was to encourage use of generators and generator expressions — it’s definitely intentional, because things like `apply` and `reduce` used to be builtins but now they’re imports. If you reach for itertools imports often in an interactive REPL, you might be interested in Pyflyby: https://labs.quansight.org/blog/2021/07/pyflyby-improving-ef...

HN discussionTravis Oliphant, here. OpenTeams is much bigger than me, but I have been part of the early team putting energy into the effort. Henry has captured some of the personal motivations for me. They are sincere. There are plenty of ways for me to make money more easily than wrestling with the economics of open-source software. This is my calling and something I care about a lot. You can watch a video of me talking somethi…

HN discussionThe no-GIL work (free-threading) is unrelated to this incremental GC work. Free-threading actually uses its own, separate GC: https://labs.quansight.org/blog/free-threaded-gc-3-14

HN discussionI hadn't realized how popular the `regex` package is ( https://pypistats.org/packages/regex ). That's almost as frequently downloaded as `build`, the PyPA standard build front-end, and well ahead of e.g. `ipython`. One common frustration with Python development is that people with new ideas nowadays are often dismissed "for now" and told to implement their idea as a package and put it on PyPI, and demonstrate that t…
