Hello #fediverse #introduction

I'm Michael, professor in the institutes of #mathematics and #materials science and head of the @MatMat group at #EPFL.

I work on the #atomistic simulations of materials, mainly density-functional theory (DFT) methods, understanding #simulation errors and #uncertainties in predicted materials properties.

I use techniques from
#physics #computerscience #machinelearning and
develop related #julia packages such as the density-functional toolkit (#dftk).

Today is I Love Free Software Day.

All our services and free software products stand on the shoulders of giants.

Thank you @fsf @fsfe thank you #rstats, #Python and #Julia. Thank you #Rust, #Kotlin, #C++ and #Java. Thank you #Kubernetes, #Singularity and #Docker.

Thank you to all the free software developers behind these and other projects!

Remember when I mentioned we had ported our #fire propagation #cellularAutomaton from #Python to #Julia, gaining performance and the ability to parallelize more easily and efficiently?

A couple of days ago we had to run another big batch of simulations and while things progressed well at the beginning, we saw the parallel threads apparently hanging one by one until the whole process sat there doing who know what.

Our initial suspicion was that we had come across some weird #JuliaLang issue with #multithreading, which seemed to be confirmed by some posts we found on the Julia forums. We tried the workarounds suggested there, to no avail. We tried a different number of threads, and this led to the hang occurring after a different percent completion. We tried restarting the simulations skipping the ones already done. It always got stuck at the same place (for the same number of threads).

So, what was the problem?

1/n

For 2024, I solved Advent of Code in 25 different languages. Was a fun project, sometimes a bit (very) painful (*glances at Erlang and Zig*).

Code (bottom of post) and summary for each language:
blog.aschoch.ch/posts/aoc-2024

Keep in mind that I used most of these language for a few hours tops, so my judgement is very much subjective.

What's your favourite of the bunch?

Advent of Code 2024: The First Week

AI has changed programming forever. It has changed Advent of Code and the way I work. What's life going to be like when AI can do my job, better than me?

any good reason why #rstats says a zero length string has length 1?

#python: len(“”) == 0
#ruby: "".length == 0
#node/#deno: x.length == 0
#julia: length(“”) == 0
etc.

Calling all data storytellers — the first #Closeread Prize is here!

Andrew and I have teamed up with the kind folks at @Posit who have put some amazing prizes on offer to the most creative, engaging and technically accomplished examples of scrollytelling with Closeread and #QuartoPub — whether you're using #rstats, #python, #julia or #ojs or just want to tell a cool story with no coding at all.

There are some tools I'm just never going to get the chance to use professionally. I'd love to use #julia and #typst but everyone else is using #python and #MicrosoftWord and I'm never going to convince people to switch...

At least python is decent, I hate Word with every fiber of my being
