Angela Davis, bell hooks qui incarnent la convergence des luttes. Safiya Noble, dans la même veine mais avec la tech en plus. Sara Marcus ou Manon Labry, dans un registre plus bruyant, qui ont été actrices du mouvement qu'elles étudient et qu'elles ont chroniqué (les riot grrrls)
If you'vee ever spent some time installing packages, you have to check this talk! You'll definitely laugh, and maybe cry a little remembering the days spent installing (or at least trying) your most dreaded piece of software. I've spent 15+ years doing that, I can tell you everything is true
The recording of my "How to Make Package Managers Scream" talk at FOSDEM'26 is now available, enjoy!

J'avais accompagné un voyage en NZ par la lecture Keri Hulme, The Bone People. Pas mal de termes maori non-traduits et de Kiwi slang, ce qui participe à la richesse du livre — mais ce n'est pas le plus difficile, étant donnés les thèmes abordés

I see there’s a post about microplastics going around with a photo of drinking straws, so here is my semi-regular reminder that the 3 biggest sources of microplastics are tires (45%), synthetic clothing particles (35%) and paint (~10%).
Lay article attached:
I'm sure someone is gonna write a wrapper!
Going to be there, as I have been for the past few years!
Schedule for #HPC, Big Data, and Data Science devroom at FOSDEM'26 (on Sun 1 Feb 2026, in Brussels) has been published: fosdem.org/2026/schedul...
Tik tok, the clock is ticking…
Only 10 more days left to submit your talk proposal for the #HPC, Big Data, and Data Science devroom at #FOSDEM’26 !
hpc-bigdata-fosdem26.github.io
Same goes for pretty much all of the other devrooms BTW…
See fosdem.org/2026/schedul...
Just want to emphasize here that this is an image of an INTERSTELLAR COMET taken by a camera orbiting MARS. Space is so cool!
Great interview of Ian Buck on NVIDIA's vision on the future of HPC.
Few important messages:
"AI is a tool, one of many tools to be able to do scientific discovery"
"FP64 is a requirement"
"It has to be great at simulation; it has to be great at AI; and it also has to be a quantum supercomputer"
By annual tradition, the HPC, Big Data, and Data Science devroom will be part of FOSDEM again next year (Sat-Sun 31 Jan + 1 Feb 2026 in Brussels). \o/
Please help us spread the word, and/or submit a talk proposal by 1 Dec 2025.
All details available via hpc-bigdata-fosdem26.github.io 🍻
Deadline for submissions for the 11th #HPC, #BigData, and #DataScience devroom at #FOSDEM26 (Brussels, Sat-Sun 31 Jan + 1 Feb 2026) is Mon 1 Dec 2025. Please see details at the link below. Looking forward to another dynamic, exciting, packed session! https://hpc-bigdata-fosdem26.github.io/
Black and white photo of Karl Weierstrass in his later years. His white hair is receding, longer in the back, and he is wearing a dark suit with a white collared shirt underneath.
Mathematician Karl Weierstrass was born #OTD, Halloween, in 1815. 🧪 🎃
The fools at The Academy all said he was mad, but he showed them all in 1872 when he announced that he had created a MONSTER. Let's learn about the terrible thing he did.

The said hair product is probably Pedro L'Âne
Already have my train tickets and hotel booked, very much hope that the HPC devroom will be there!
For some time there was the argument that Linux was no good for gaming, but in the past few years I heard more and more good things about gaming on Linux so it's not anymore an argument.
To add some weight for Linux: most of the open source software is more than good enough (LibreOffice, Gimp, Inkscape, VLC...) and for personal use I've never needed anything more.
Linux is obviously a good choice, it's lightweight, it mostly just works, you have full control of your computer and even for non technical stuff, it's much easier to do things in bash than with a GUI (a good example is changing metadata from thousands of pictures)
From the little experience I have with Mac I find them frustrating because it looks like Linux but it's not with slight differences that makes you bang your head against the wall sometimes. Probably less frustrating for *BSD users though. Oh and the Mac keyboard is very confusing to me too.
Only Linux for the past 18 years (work and personal use), mostly Dell and ThinkPad. No real issues apart from the occasional driver problem on Dell. On the long run ThinkPads are a bit more solid, but Dell are pretty good (the non pro versions less so). Don't like the ThinkPad keyboard so much.
I was writing exactly the same; there's an "infrastructure" side of putting up such a cluster that is not visible with a laptop. If you are an end-user, a couple of containers is great. If you want to understand how a cluster works with its constraints, then a RPi cluster is great.
There's value in doing so for educational purposes though, ICHEC has a little cluster they displayed at events like ISC, and I remember a talk at FOSDEM (archive.fosdem.org/2020/schedul...) about it.
Having the flops doesn't mean you can use them with your code. Using them doesn't mean your algo & science is solid. Using them w/ solid algo/physics doesn't mean you can efficiently analyze the data. Analyzing the data doesn't mean you have a profound understanding of the problem you study...
And there are already real-life examples where the efficiency of AI exceeds by far the classical approach one, for both power and accuracy. One of my favourite examples for the past couple of years has been FourCastNet (docs.nvidia.com/deeplearning...); this kind of achievement is amazing
💥Spack v1.0 is out!💥
This is a huge milestone. We reworked the core to add compiler dependencies, and we're introducing a stable package API.
🚀1.0 also adds concurrent builds, better includes, and much more -- read it all in the release notes!

It's not that surprising as -- at least in Europe -- lots of AI factories are actually pre-exascale and exascale EuroHPC systems.

I worked at the Living Computer Museum from 2014 until it closed due to Covid (and then never reopened because Paul Allen did a shitty job with his estate planning.) It's been a bit over 5 years since the museum closed to the public and I thought I'd share some pictures I took around that time.
