Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust.

In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

YouTube video by marimo Make *really* good looking charts with pyobsplot

Apparently someone made a video about pyobsplot and its use in a Marimo notebook:

Yellow fields or dark green fields? 💛💚 These are the other two aerial embroidery landscapes that will be available on my site later - and I couldn't resist more oilseed fields! The right one started with the fun path shapes :) all here: victoriaroserichards.co.uk/collection/a...

Congratulations! Great news for you and for us!

New released pyobsplot version should now work on Marimo notebooks (and other pyodide based environments).

pyobsplot is a Python package allowing to create plots with Observable Plots with a syntax close to the JavaScript one.

It's quite sad how many early internet open protocols are slowly dying because companies are incentivized to lock in their users.

I love these! Such a variety of forms achievable with just small parameter tweaks.

Today I learnt about GOOD, a web search engine based in Germany which claims to be privacy friendly and to use an independent search index (the same as Brave).

Far from as featureful as Kagi, but results seem ok. It is based on an affordable subscription model (2 euros per month).

Snippet from a WSJ article saying : At a Morgan Stanley conference this month, Brian Robins, finance chief for San Francisco-based software maker GitLab, said GitLab is aligned with the goals of DOGE, because the company’s software tools aim to help people do more with less. “What the Department of Government Efficiency is trying to do is what GitLab does,” Robins said.

Time to go away from Gitlab too, it seems...

I use it daily, it is super useful. Many thanks for your work.

We’re building a new static type checker for Python, from scratch, in Rust.

From a technical perspective, it’s probably our most ambitious project yet. We’re about 800 PRs deep!

To "celebrate" the inauguration I've donated money to Planned Parenthood, Translifeline and The Trevor Project. The next few years are going to be chaotic so I'll be striving to ignore the things outside my control while doing my best to support the communities that I can help.

Just a regular reminder: the ArcticDEM is one of the most beautiful spatial datasets out there. I've been working on a large tile set for our #arctic abrupt thaw mapping activities recently and I can't help but stop and take a peek as the data rolls in.

Nothing incredible and I'm clearly not a designer, but I've been quite happy to make a bit of #d3 again and to see that I still know a little about it.
