I love Python, R, and Julia, and I combine their power to do neuroscience, EEG processing, machine learning, and applied statistics. I am currently working as a senior scientist at University of Graz, Austria. cbrnr.github.io · scholar.social/@cbrnr

I've just released MNELAB 1.0.4 (a GUI for MNE-Python, a package for analyzing EEG/MEG data), which now includes standalone installers for macOS and Windows:

Newsflash: Fliegen kann man nicht billiger machen. Man kann nur erreichen, dass die, die fliegen, weniger zahlen. Die Schäden, die dadurch entstehen, müssen von allen anderen gezahlt werden.
Hätten wir Kostenwahrheit im Transport, würden wir längst hektisch Highspeed-Zugnetze bauen.

#rstats 4.5 now includes the `penguins` data frame! 🚀

Clemens Brunner @cbrnr.bsky.social · Apr 16

When installing #rstats on #macos, installing packages defaults to the system library. R won't use the user library (~/Library/R/arm64/4.5/library) unless I *manually* create it. On Linux and Windows, R creates this location automatically. Is this intentional? It feels unintuitive and inconsistent.

Do you use #vscode? Have you ever wanted the Explorer view in the sidebar to just show all tracked files under version control? I made a feature request, give it a thumbs up if you think it would be useful!

Only show tracked files/folder in Explorer view · Issue #244951 · microsoft/vscode

I don't know if I'm missing something, but currently I don't think it is possible to have the Explorer view only show tracked (i.e., under version control) files/folders. I know that there is a set...

#Electron apps cannot be resized on #Wayland anymore, at least on #GNOME. Given that GNOME defaults to Wayland nowadays, I wonder why so few people experience this problem, since it affects VS Code, Signal, Discord, and so on. If you can help, please check out github.com/electron/ele.... #Linux

Ja, ist mir schon vor einiger Zeit positiv aufgefallen! Jetzt fehlt nur mehr ein Mastodon-Account 😉.

Clemens Brunner @cbrnr.bsky.social · Feb 10

I'd say yes, because instantiating a project is instantaneous (if you've downloaded the packages before). However, there are alternatives, such as running just the script, or even `uvx python` (short for `uv tool run python`) for spawing a REPL. I'm still learning new things about uv every day too!

Clemens Brunner @cbrnr.bsky.social · Feb 10

Exactly! Alternatively, if you don't want to create a project, you can even include it in the script directly (see docs.astral.sh/uv/guides/sc...).

A guide to using uv to run Python scripts, including support for inline dependency metadata, reproducible scripts, and more.

Clemens Brunner @cbrnr.bsky.social · Feb 10

And I also agree, maybe it's still too early times. IDE integration could also be much improved with native uv support for example!

Clemens Brunner @cbrnr.bsky.social · Feb 10

I guess my point is: uv is the greatest thing Python tooling has ever seen, but you cannot and should not expect it to work just like pip and venv!

Clemens Brunner @cbrnr.bsky.social · Feb 10

uv requires you to re-think many things you have gotten used to. It took me a while to wrap my head around. It doesn't work like pip, but you can (but probably shouldn't) use `uv pip` (e.g. you can `uv pip install` packages into the corresponding venv, which you can manually create with `uv venv`).

Clemens Brunner @cbrnr.bsky.social · Feb 10

Using the official installers is a good solution! But I don't think you should blame uv here, it sounds like an IDE-related issue. In VS Code, you can set the interpreter for a project, then it will use the venvby default (`python` works). Also, there is no global Python in uv (you don't need it).

Clemens Brunner @cbrnr.bsky.social · Feb 10

I think this is kind of the point, you should never have to think about environments. If you hate running `uv python`, then you can always activate the underlying venv to use `python`. Although I'd be interested to know what's bothering you.

Python 3.13 currently has a known issue on Windows that prevents users from pasting code snippets containing indentation into the new REPL.

Ja, vermutlich damit dann noch mehr Chalets in die Berge gebaut werden können...

Clemens Brunner @cbrnr.bsky.social · Dec 19

Does anyone else find it irritating that the default behavior of #RStats on #macOS installs packages to the system library instead of the user library?

I think the problem only occurs if the directory does not exist. If I manually create it, then everything works.

Is this a bug? Or is it just me?

Also, Excel cannot open more than one file with the same name, but in different folders, at the same time (at least on macOS).

Here's my #AdventOfCode Day 6 solution in Julia:

Not optimized at all, so Part 2 takes a few seconds, but I'm quite happy with the solution.

Nothing fancy to see here (no graph-related algorithms), just some nice function vectorizations made easy in Julia. In Part 2, I simply swap items for each incorrect rule until all the rules are satisfied.

Yeah, I guess (2) is the correct definition from a technical point of view (since methods are just callable attributes). But I still think of attributes vs methods, maybe because other languages make a clearer distinction.
