Cat points out a real problem. Rather than “everyone builds their own custom app” with all the overhead that entails, my working hypothesis is that we’ll see an explosion of what @inkandswitch.com calls malleable software www.inkandswitch.com/essay/mallea...
A solid core + ability to extend
I whipped up another learning related Skill! Smaller than Learning Opportunities, but very complementary: interactive guidance through a quick research-backed psychological intervention that helps improve learning plans, motivation and commitment

Key to efficient learning is realizing how we ACTUALLY learn, not just what FEELS like learning. I wrote a Claude Skill for some friends to help them think about this and they've liked it -- see Principles for some directions you could explore

Outer Wilds, if you haven't played it yet, is one of the best games of all time. It's a fun space exploration game with a timeloop twist, and 90% of all game progress happens in your head, as you learn things about the universe and your situation.
Absolutely play it if you haven't yet.

Yeah, in this case, I think it might be more related to tolerating missing libs or old versions of plugins or something than to the file's kicad version (which is indeed kicad 6). Kicad just closes with no error message
It been 0 days since @thea.codes 's KiCanvas saved my bacon again by opening an old layout file that was crashing KiCad.
If you're using KiCad for PCB design and haven't seen KiCanvas, give it a look! kicanvas.org

Hey kids, wanna see the embassy executor running on a GPU?
Terminal with three panels. Top-left shows "zoo kcl analyze" command output, with a table showing mass, density, volume etc. Bottom-left panel shows "zoo kcl view" displaying four different angles of a model rendered as PNG. Right panel shows the KCL code for the model.
I added a new helpful one-stop-shop for all your physical analysis in Zoo's CLI. Find your model's mass, volume, surface area, etc with "zoo kcl analyze".
I just wish more web ui systems were aware of this. Some like Material and whatever github uses only render svg once, and don't re-render when CSS changes for dark/light mode, so even if you put CSS in your SVG to switch between light and dark mode, it won't actually update until refresh
hey uhhh. I got fired yesterday. if anyone has rust positions in the Netherlands let me know!

screenshot from C11 standard, appendix J.2, specifying that "The behavior is undefined in the following circumstances: — A ‘‘shall’’ or ‘‘shall not’’ requirement that appears outside of a constraint is violated (clause 4). — A nonempty source file does not end in a new-line character which is not immediately preceded by a backslash character or ends in a partial preprocessing token or comment (5.1.1.2). ..."
today i learned that if you don't end a C file with a newline, the compiler is free to steal your apes
Yeah, among other things, they set global flags that clip subnormal numbers to zero
Many of the #rust floating-point math functions have a note:
"The precision of this function is non-deterministic. This means it varies by platform, Rust version, and can even differ within the same execution from one invocation to the next."
When would results vary between invocations?
#rustlang
libm implementations are a little slower sometimes, but imo it is well worth the cost to achieve real cross-platform consistency, especially in scientific computing
I recommend using libm for any functions with that label unless you know they'll get compiled to a single instruction on your target platform (like sqrt() for example)
If you load a C module that uses -ffast-math, or if libc gets hooked and modified, it can change floating-point calculation behavior in your otherwise-separate program. I think there are also some function implementations that don't write all the bits of the float in some cases, so you get some junk

A picture showing an example output of the program on the city of Montréal and the autumn color scheme. You can see a map of the city with all the roads, trains, subways and light rail. At the bottom there the poster is titled MONTRÉAL - QUÉBEC. The latitude and longitude are also written under the title.
A picture showing an example output of the program on the city of Paris and the emerald color scheme. You can see a map of the city with all the roads, trains, subways and light rail.

A little python program that generates poster for cities! You might have seen stuff like this around lately, but I modified it to put an emphasis on rail infrastructure :3

First Scientific Computing in Rust monthly newsletter of 2026 is out. Enjoy!
scientificcomputing.rs/monthly/2026...
We are excited to announce that we can successfully use Rust's standard library from the GPU. This has never been done before.
www.vectorware.com/blog/rust-st...
Supporting Rust's standard library enables existing Rust code to work on the GPU and makes GPU programming feel normal.
The library is available as a Rust crate and Python library at:
* Github: github.com/jlogan03/int...
* crates.io: crates.io/crates/interpn
* PyPI: pypi.org/project/inte...
