TMLR has been facing an significant uptick in the number of submissions since the start of 2026. This is placing an extreme burden on our amazing team of reviewers & action editors. To ease this burden, TMLR will be implementing submission quotas, effective July 1. 1/n medium.com/@TmlrOrg/ann...

Very exciting to see the team behind PyData Paris crossing language borders! I'll definitely attend 👀

Pretty late to the party, but I was honored to receive the Robert Faure prize 2026 from the French Operations Research Society! matbesancon.xyz/post/2026-04...

Crossword pro tip: solve it as a team with your smarter girlfriend. First time under an hour for a Sunday grid!

I find it extremely comforting to know that Python development will basically be revolutionized every two years by @crmarsh.com and his crew at Astral. astral.sh/blog/ty

IJCAI 2026 will charge $100 USD per submission. Funds will be used to compensate reviewers. 2026.ijcai.org/ijcai-ecai-2...

Note to self: create a second Spotify account to work on song covers. Maybe this will allow my end-of-year recap to not look like an obsessive French pop fever dream.

Awesome to see the French government recognize our work on open-source software! @ouvrirlascience.bsky.social

My baby #JuliaLang package got an award! DifferentiationInterface.jl just received a national prize for open-source research software and I couldn't be prouder. We started this from a vague dream with @adrianhill.de, and reached 1000 dependents and 100k downloads last month. Research != just papers.

Trying to learn Rust for the Advent of Code, and literally every page of the manual has me going “wow, that *is* a problem I encountered in other languages and what a clever way to solve it”.

Yes!!! This is what prompted me to write the following paper: dl.acm.org/doi/full/10.... A lot is explained by narratives and social norms driving research. We need to build our own narratives, as a research community, this is what we do

Don't mind me, just going through old, irrelevant posts

each poster session at #neurips2025 has about 1000 posters. stupid question but isn't that too much?

Monotone operator theory be like: every algorithm is a fixed-point algorithm. A strangely comforting idea.

⚠️ WANTED: PhD student ⚠️ The topic? GPU-friendly algorithms for discrete optimization and mathematical programming, to be used inside decision-focused learning pipelines. The mentors? My colleague Axel Parmentier and myself. [1/3]

Teaching a class on decomposition methods for MILPs tomorrow and I'm wondering what the modern alternative is for "master problem" (as opposed to the pricing subproblem). Any suggestions? I've been using "main problem" but it feels too generic.

Note to self: in the future, check the author names twice *before* sending review invitations. This lesson is sponsored by the Shameful Society of New Action Editors who Invited Authors to Review their Own Paper.

OpenReview? More like BrokenReview, amirite?

Gotta love how objectively insane it is that we even have to say this out loud.

Doing my first reviewer assignment as an editor, and I can officially confirm: we need fewer papers and more reviewers.

Happy to announce that I joined the crew of @tmlrorg.bsky.social as an action editor 📝 We need a publication model with the fast turnaround of ML conferences but no attendance requirement and less reviewer lottery. I believe TMLR is part of the solution, and if you do too, come review with us!

I’m recruiting a postdoctoral researcher on a fully funded 2-year contract. The topic is developing and implementing new parallel graph algorithms, with applications to data-driven transportation and logistics. Details and application procedure below ⬇️ Reach out if you have any questions!

I’m reasonably confident that this is the first Disney song cover about machine learning conferences. At least the first one so far. Don’t tempt me. #MLSky youtu.be/kWkgl9Mb2p4?...

JuliaCon Local Paris 2025 is a wrap! Thank you so much to all of our attendees and presenters, who made this conference a wonderful mix of software and science. Next step: watch out for the talk recordings on YouTube... and see you next year in Germany! www.youtube.com/playlist?lis...

Periodic appreciation post for this gem of a review by Hannah Bast and coauthors. If you think you know how to compute shortest paths... trust me, you don't. I can give you one spoiler though: preprocessing the graph helps A LOT. doi.org/10.1007/978-...

Me this morning in front of a class: “So Euler wanted to cross all 7 bridges exactly once during his stroll…” An inquisitive high school student: “Was Euler smoking opium?”

The European open-source community is growing, and it's only the beginning! See you all in Paris 🥐

JuliaCon Local Paris starts tomorrow 🤩 Which part of our amazing program are you most excited about? #JuliaLang @juliacon.bsky.social @julialang.org

Can anyone recommend good substacks in the AI / ML / OR space? What are y’all reading?

Meet our second Platinum sponsor for the Paris event! CodeGlass helps software teams look inside their running #JuliaLang applications, with profiler and time-travel analysis tools. Wanna trace performance and memory back to the lines of code that really matter? Check them out 👀

JuliaHub has sponsored every single JuliaCon since 2014, and this year is no different! Check out their JuliaCon Global 2025 Pittsburgh Sponsor Talk, and look out for them at JuliaCon Local Paris in a few weeks! youtu.be/zCUQfE-MGgM

After more years than I care to admit, I am pleased to announce that I finally know what the fuck Farkas' lemma was trying to tell me all along. en.wikipedia.org/wiki/Farkas%...

This is not OK. I don't submit often to NeurIPS, but I reviewed papers for this conference almost every year. As a reviewer, why would I spend time trying to give a fair opinion on papers if it's what happens in the end???

@neuripsconf.bsky.social decisions and stats are out. Definitely sad that a great initiative was set up but NOT what it should be: a third option to avoid 5000 authors burning kerosene crossing the world to present 8 pages

It may only be a band-aid, but we have just announced our new "Salon des Refusés" sessions for papers rejected due to space constraints: bsky.app/profile/euri...

Congratulations to everyone who got their @neuripsconf.bsky.social papers accepted 🎉🎉🎉 At #EurIPS we are looking forward to welcoming presentations of all accepted NeurIPS papers, including a new “Salon des Refusés” track for papers which were rejected due to space constraints!

Is this the year we finally break up @neuripsconf.bsky.social?

Very happy to see #JuliaLang percolating into European tech... especially in such a critical sector!

It's too late to sponsor this year's edition, but if your firm wants to sponsor the 2026 event in Mainz, do reach out!

Software enthusiasts of all fields and backgrounds, unite! Here's the exciting schedule we cooked up for #JuliaCon Local Paris 2025 (the one for #PyData is just as thrilling!). Get your tickets while you can, and see you in a month ⌛ @julialang.org @juliacon.bsky.social @pydataparis.bsky.social
