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”.

⚠️ 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.

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!
