Probably my lazy french brain but some journal allowing delays in paper reviews for "exceptional personal circumstances (e.g. vacation)" gets my teeth grinding hard 😬
Of course with 3 vacation days per year I guess that falls into exceptional

Barely have a permanent position and already called old by the new generation, academia is brutal

- Mixed-integer optimization is so second-nature to us operations researchers, it's easy to forget most people approach their combinatorial problems through polyhedral relaxations
- and conic formulations, of course

I don't know if there is a North-South divide on that, but have to say that the train in Italy has been one of the best 🚆 experiences for me this year (on the Torino-Bologna-Rome line)

I know what I'm reading on my train trip this week! Sophie and Eleon bridging the gap between analysis of algorithms and real-world computational optimization 🎉
The simplex algorithm is super efficient. 80 years of experience says it runs in linear time. Nobody can explain _why_ it is so fast.
We invented a new algorithm analysis framework to find out.

Beyond Smoothed Analysis: Analyzing the Simplex Method by the Book
Narrowing the gap between theory and practice is a longstanding goal of the algorithm analysis community. To further progress our understanding of how algorithms work in practice, we propose a new alg...

My usual system, inspired by my PhD advisors, is first author (quite often a younger scholar), and then the rest in alphabetical order. This means I'm typically the second author, minimum contribution according to Google Scholar it is 😑
🧪For those of us who do complex collaborations with multiple corresponding authors this is terrible . I suspect it will also hit female authors disproportionately as they tend to have more collaborations across fields…https://www.nature.com/articles/d41586-025-03281-4
Google Scholar tool gives extra credit to first and last authors
Researchers welcome the initiative, but say it doesn’t go far enough to capture the nuance of researcher productivity and impact.

Life goal: being so good at extreme irony-ing you get second degree burns
TIL: 🤔
Extreme Ironing is an extreme sport in which people take ironing boards to remote locations and iron items of clothing.
"the latest dangerous sport that combines the thrills of an extreme outdoor activity with the satisfaction of a well-pressed shirt."

Authors generating pieces of their paper with LLMs: this is saving some research time in the same way throwing garbage out the window is saving home chore time.
And yes the comparison is exactly my feeling after the tenth useless adjective and repeated sentence.

@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

Being a journal website in STEM should not need so many things:
1. a page for each paper
2. a download paper button
3. a get citation as bibtex option
Why on earth does INFORMS not have 3? One can only copy the text format of the citation it seems

I'm probably going to regret this rabbit hole... do people here have a text editor they like that is:
- not modal
- configurable enough
I've been using micro for almost 10 years but some go features make it a bit of a pain on some systems (don't ask me how I found out)
