Congratulations to my colleague Subhash Khot (down the hall), Irit Dinur (across the river and through the woods), Dor Minzer (up the coast), and Guy Kindler and Muli Safra (across the seas), who just got the 2026 Held Prize for their groundbreaking work on 2-2 games!

Did you know? 2026 is one of the integers which, when divided by the sum of the squares of its digits, does nothing particularly remarkable

Fair Allocation of Indivisible Goods with Variable Groups
https://arxiv.org/abs/2511.06218
The SACT group at #USyd 🇦🇺 has a number of postdoc positions available (2+ years) in all areas of TCS, with one focusing on streaming and one on planning and synthesis. Expected start mid- or end 2026.
Excellent candidates are encouraged to contact us by email, or during #FOCS2025 #TCSSky

Alongside the new bulletin, is the first video on the new EATCS Youtube channel!
We learn about different ways to record your seminar talks.
A screenshot with a short excerpt from the the interview. Question: Are there any blog posts you’d like to highlight from over the years? Gautam: I really like posts that share more about the humans behind the research. Omer Reingold ran a series on “research-life stories,” a great representative one is Bobby Kleinberg’s. Luca Trevisan had a series of posts from gay and lesbian computer scientists in commemoration of Turing’s 100th birthday, you can read his own account here. Arnab: Completely agreed with Gautam. I’d also like to highlight Gil Kalai’s valiant effort at “Combinatorics and More.” Gil’s blog has been actively maintained since 2008! It’s still often the first place to break news about advances in combinatorics.
The new EATCS Bulletin #147 is available!

In the TCS on the Web Column, I talked to the maintainers of the TCS Blog Aggregator: Nima Anari, Arnab Bhattacharyya and
Gautam Kamath.
It was a very fun interview!

A little-known algorithmic process called “differential privacy” helps keep census data anonymous. Conservatives want it gone.
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.
