GitHub - jolars/panache: A formatter for Pandoc, Quarto, and RMarkdown A formatter for Pandoc, Quarto, and RMarkdown. Contribute to jolars/panache development by creating an account on GitHub.

I've made an autoformatter, linter, and LSP for Quarto, Pandoc, and RMarkdown documents! It's still very much a work-in-progress; only the formatter is reaching something resembling a mature state. Check it out at https://github.com/jolars/panache

Introducing Tomat: A Pomodoro Timer for Status Bars I’ve decided that the world needs yet another pomodoro timer. yapm was unfortunately already taken, so I named it after the Swedish tomato.

One of the new title pages of moloch, which uses a split layout.

I just released moloch 2.1.0, with support for configuring the style of the title page!

At the moment, I've added two styles beyond the default: one mimicking the standard beamer style and one that uses a split style (see below).

Causal Graph Interface Create, query, and modify causal graphs. 'caugi' (Causal Graph Interface) is a causality-first, high performance graph package that provides a simple interface to build, structure, and examine causal relationships.

If you're working with causal graphs in R, then take a look at caugi, which is an R package by Frederik Fabricius Bjerre that I supervised the making of. It's blazing fast (built in Rust) and intuitive to work with.

Moloch - A Minimalist, Feature-Rich Beamer Theme Moloch is a minimalist, feature-rich Beamer theme for LaTeX presentations with a clean design and extensive customization options.

I've spent a bit of time updating the documentation for my LaTeX Beamer theme Moloch. In particular, it now contains documentation in the browser at https://moloch.ink ! Hopefully this makes it easier to discover and understand the available options for configuring the theme!

Yes, the documentation is not great, and I think using NaN was a bad idea from the start, but it has history going back a long time. Maybe `Undef` would have been a better idea.
I guess the difference between NaN and NA is actually well-defined, and the problem is more nomenclature + documentation?

New paper on the generalization of Flow Matching www.arxiv.org/abs/2506.03719

🤯 Why does flow matching generalize? Did you know that the flow matching target you're trying to learn *can only generate training points*?

We want to thank Posit for their support! With Posit’s help, we were able to grow our team by one full time engineer, committed to make the Typst compiler even better ❤️

I had a blast giving a summer school on generative models at AI Hub Senegal, in particular flow matching, with @quentinbertrand.bsky.social and @remiemonet.bsky.social

Tariffs xkcd.com/3073

Just figured out where these fake tariff rates come from. They didn't actually calculate tariff rates + non-tariff barriers, as they say they did. Instead, for every country, they just took our trade deficit with that country and divided it by the country's exports to us. So we have a $17.9 billion trade deficit with Indonesia. Its exports to us are $28 billion. $17.9/$28 = 64%, which Trump claims is the tariff rate Indonesia charges us. What extraordinary nonsense this is.

james surowiecki has discovered where the completely fabricated trump tariff rate has come from for each country

"...for every country, they just took our trade deficit with that country and divided it by the country's exports to us."
