TCS in a nutshell? 🙊

Same thing for academics: you're writing for that paper? Adds time. Working on the content, proofs, experiments? Adds time. Tweaking the latex template? Substrat time. Getting an LLM to mess up the template for you? Remove all the time budget.

Asking here in case: does anyone know a good jurist or lawyer in Germany specialized in citizenship, the precise requirements for applications? Not for me, and yes this is for an edge case of the standard procedures

I was surprised they ended up saying "hey fine use AI to review but give us your prompt if you do"

French tenured positions have been pretty forward-thinking on this: committees ask for candidates' top-k papers, with some members assigned to reading and evaluating said papers. k=5 at for junior (assistant professor) roles and 10 for senior (full prof)

I reviewed way too many papers this year. Frankly I would probably decline reviewing for a venue that explicitly puts the pressure of evaluating (and thus understanding) slop on the reviewers instead of the authors

I think this class would be a great entertainment & education piece to opt researchers as well. You had me at "This is a terrible situation that must be avoided at all costs."

That would have been a highlight of the day! I just passed by both, had a change in Brussels but not even enough to get the waffle myself Another time!

And when I say I got Deutsche Bahned, I don't mean a cute little delay, I mean that I should be around Burgundy and I'm currently watching someone eat a Belgian waffle 🫠

@deutschebahn.com has Deutsche Bahned me again: insane delays but not enough to claim reimbursement, missed connection to an international train and left to fend for myself finding another connection Is it me or is network reliability getting *even* worse? Are there dashboards monitoring it?

C'est futé d'avoir laissé un bout de métal coupé dépasser du sol 🫪 Je sais pas si ça aurait été laissé tel quel sur la voirie motorisée

Les seuls trucs que j'utilise sur ces pages horribles c'est essayer de télécharger le PDF et essayer de trouver l'entrée bibtex, mais un chatbot c'était plus important 🫠

Oh yes that was clear sorry, it was just a spontaneous thought from seeing the location :)

Does CVPR have remote options similar to generic ML conferences? Especially since the venue is in the US

Le bug venait de l'interface ocaml ou de la shared lib appelée par celle-ci ? Je ne suis effectivement pas sûre que ça soit l'interface à Gurobi la plus scrutée

And you'd think that a 45 min correspondence is enough to be safe, you'd THINK

Mathieu Besançon @matbesancon.xyz · 29/08/2026
Deutsche Bahn advertising *relaxed* trips on the screen while I spend 4 hours estimating our real delay and plausibility of my correspondence because their updates are systematically over-optimistic. Did not miss this 🫣

I get that @arxiv.bsky.social is under massive submission loads, but not all rules give good filters. Our paper got flagged for repeated text. Without more info, we can only guess that it is about restated things (w/ thm-restate). But it has the .tex source, it could check the source directly no? 🤔

Mathieu Besançon @matbesancon.xyz · 24/08/2026
Well in that case it seems one of my trains is just... gone? Luckily there is a replacement, because my second train is a once-a-day cross-border that would have been pretty critical to miss

I like living risky but receiving the dreaded "Changes of your trip" email from Deutsche Bahn, that's too much

MPC is one of the flagship journals in optimization, it filled a crucial gap at its creation for the recognition of computational work and solver development in mathematical optimization

Damn indeed. Except CORE ranks have for legacy reasons more of an aura to them

Mathieu Besançon @matbesancon.xyz · 29/07/2026
Whatever we think of CS conf rankings, they are used by hiring committees, etc. The sub-domain bias is pretty striking on CORE. The few integer optimization conferences are now all rank B I believe. Searching for computer vision gives me a bunch of A* ones.

So have we reached the "Freedom Waffles" stage on every US menu already?

@proton.me I haven't found a definitive answer on the various forums, is there a way to "send as" in proton from another email (a professional email)? For academics that have 3+ email addresses this is essential

Mathieu Besançon @matbesancon.xyz · 25/06/2026
For academics organizing workshops: EasyChair or ScienceConf? I could cope with making a website separate from the CFP if needed.

Mathieu Besançon @matbesancon.xyz · 21/06/2026
I know the intent is good but all papers having an appendix section "AI good and bad we just do the method" is not adding any value

Mathieu Besançon @matbesancon.xyz · 21/06/2026
The blanket requirement of ML conferences on ethics and impact statements, regardless of the contribution, and without any training in ethics, is really just clutter on papers and additional noise, with the same empty paragraphs slapped in all of them.

I had never noticed americans using cheers, thought it was a British thing! So I should possibly deduce that I was always on a formal basis in any American exchange 🫥

That is exactly what I found in my previous email with that person 🥲

For people speaking languages with a distinction of formal and informal "you", are you also looking up through piles of emails to see if you're on an informal basis with someone?

I'll be at the jump.dev workshop and SIAM OP26 in Edinburgh! Come say hi to chat on computational optimization, constrained first-order methods, or hunt down the best specialty coffee and bouldering gyms in town!

Clairement c'est un usage très raisonnable, en le faisant chapitre par chapitre même, et en ne gardant qu'un peu d'ajustements cosmétiques à la fin

Oui, il y a un peu de travail pour les blocs multi-equations, si il n'y a pas d'agencements farfelus de diagrammes ou de Tikzeries, ça ne doit pas être affreux

La comparaison est douteuse: je ne vois pas la pertinence de mettre sur le même plan des militants exprimant des opinions et des personnes qui ont opéré au sein d'un gouvernement et ont pris des décisions arbitraires sur des programmes de recherche qui les dépassaient
