oof: my political enemies have interesting research problems

Pigoneer Pig Of The Day Squidgy! One of the original #53 pigs, Squidgy is so called because he has the most squidgy face & enormous tusks. He is one of a group of five very large boys at BTW Sanctuary. Join the Pigoneers help support Squidgy & friends⬇️ globalvegancrowdfunder.org/pigoneer-200...

Companies in our industry should follow this example. Whoever sells the IDF a MIP solver is complicit in the atrocities

sorry i can't reply to your emails right now. if your request is urgent, you can find me playing #Hades2

The simplex method was obviously invented in the United States, as it needs to avoid cycling. (poke @sophie.huiberts.me)

i often find myself talking about the xpress applications book. it's an amazing collection of uses of LP my only gripe is its age. does anyone know if there is a more recent alternative?

why are the bib fragments from SIAM's website such garbage, and why is doi2bib.org able to output something better?

i hear rumors that i abuse my scientific presentations to talk about Politics so let me set the record straight and repost my video about Israels war crimes in the Gaza Strip 🇵🇸

Gurobi published their 2025 State of Mathematical Optimization report. Always a nice read! www.gurobi.com/resources/re...

Dear colleagues, positions at CNRS (and INRIA) will (in all probability) be announced this winter. By then it will however be too late to properly prepare an application. Recent PhDs, postdocs etc interested in such positions should get right now in contact with teams who would like to recruit them.

I spoke at OPTIMA about the end of smoothed analysis and my recent paper with Eleon Bach

Deadline is September 25, 23:59 AoE

Professor-ing As a Brown Muslim Person in Current Times 🧵 I spent part of my math methods for pre-service elementary teacher's class yesterday connecting surveillance tech, mathematics, and techno-fascism to the planned ICE immigration raids that are supposedly happening in Chicago this weekend

The Netherlands now also has a call out to poach top international (non-EU) researchers whose academic freedom is threatened. Possibility to apply for 1M euro; need to be nominated by a Dutch research institution, which requires a recognizable strong profile. www.nwo.nl/en/calls/tulip-fund

Proud of my Alma Mater. Utrecht University joins the boycott of complicit Israeli institutions!

I've been using Goodnotes for handwritten notes and PDF annotation on iPad, but the latest version is full of all kinds of weird AI things. It's no longer as responsive as it used to be, and it is hard to trust that no information will leak to third parties. Any good alternatives?

The conjecture that every convex polyhedron is Rupert is settled in the negative! The convex body in the image cannot pass straight through a hole inside itself. arxiv.org/abs/2508.18475 #Mathematics #Geometry #MathSky

This is a good feed to have in the mixer. It shows all papers being shared by your follows

"Despite claims by Israeli authorities that there is no limit on humanitarian aid entering Gaza, most major international NGOs have been unable to deliver a single truck of lifesaving supplies since 2 March."

Sophie Huiberts (@sophie.huiberts.me), from the CNRS, will give an online talk at @optima-arc.bsky.social next week, Wed 20, 4-5pm AEST 🇦🇺, on the "Smoothed analysis of the simplex method" (settling it!) To attend, see the OPTIMA website: optima.org.au/events/semin... h/t @swumboh.bsky.social

As limited aid trickles into Gaza, Israel’s strategy of ‘engineering chaos’ by shooting at aid-seekers and permitting looters to steal aid ensures that food doesn’t get to starving Palestinians. mondoweiss.net/2025/08/isra...

Fascinating video about the history of linear programming

This is about one of my greatest inspirations. It would mean a lot to me if you gave it a watch

To reduce barriers to attendance, #FOCS2025 will try to facilitate childcare for attendees during the conference. Information, how to register your interest, and how to apply for financial support: focs.computer.org/2025/childca... Deadline (for the latter): ⏰ September 19th (AoE)

New from @michaelfakhri.bsky.social ‘Israel has built the most efficient starvation machine you can imagine. So while it’s always shocking to see people being starved, no one should act surprised. All the information has been out in the open since early 2024.’ www.theguardian.com/world/2025/a...

Everyone go read this article by Tarik Aougab! What a gift to the mathematical community

GHF brags about delivering 1.3M meals per day. Mathematicians have a moral responsibility to speak out about the fact that 1.3M <<< 6.6M

Mathematics is everywhere

Aid groups report that Israel is refusing to allow any olives or other “fruits or vegetables with pits or seeds that could be planted” into Gaza. They will only allow in pitted olives.

this is a really good article and makes very important points very clearly

“It was carefully submitted as by A.H. Land and A.G. Doig with no indication whatever that we were both women.”

This part stuck out too

There is a podcast interview with her! Props to @optima-arc.bsky.social for recording this important history

This story of the discovery of Alison Doig the person is wild pursuit.unimelb.edu.au/articles/cel...

GHF is "at best an improvisation by amateurs and at worst a cover for the crime of ongoing mass starvation."

“One in three Gazans goes multiple days without eating, the World Food Programme said this week. Malnourished mothers can no longer produce milk to breastfeed their children, the injured are unable to heal and hospitals have run out of nutritional supplements to treat gaunt babies.”

Health workers and aid groups fear hunger that has been building in Gaza for months under Israel's blockade is now reaching a tipping point into accelerating death.

Two numbers to keep in mind when reading the news this week: One truck can carry 30+ tons of food. You need 3+ airdrops to match one truck

MUST READ: The Gaza Humanitarian Foundation has taken over the aid system in Gaza on behalf of the Israeli army by cultivating a local network of companies and organizations to collaborate in its operations. The organizations that refused have been shut down. mondoweiss.net/2025/07/this...

The BBC, Associated Press, Reuters and Agence France-Presse have all called on Israel to allow journalists in and out of Gaza as starvation there becomes imminent.

Buried in Columbia's agreement/bribe with the Trump regime (and not reported by the news) is a section which agrees to segregate trans women from women's housing, sports, and bathrooms. Functionally, trans women are no longer welcome at Columbia University.

Yann and Nils had an open problem looking for a solution Eleon and I had a construction looking for a problem We found each other at a serendipitous open problem session :)

What an amazing opportunity this looks to be, getting to learn from some of the best in the field.

"I have been working on this topic for more than 4 decades. There is no case since WW2 of starvation that has been so minutely designed and controlled"
