Chen’s paper has a bug, independently discovered by Hongxun Weng and Thomas Vidick, that he doesn’t know how to fix. If I understand correctly, in its current form the paper doesn’t yield any improvement on prior algorithms. eprint.iacr.org/2024/555

The co discoverer of the bug in Chen’s paper is second year Berkeley grad student Hongxun Wu @HongxunWu ( whxwhx.github.io ). Quite impressive given several lattice experts looked at the paper closely! Sorry for misspelling the name in a late night tweet yesterday.

Last week I had the strange but very positive experience of attending a conference in celebration of my 60th birthday (which was a few months ago). The talks were wonderful but slightly hard to find on YouTube, so I've made a playlist of most of them. 🧵 youtube.com/playlist?list=…
I gave a talk a month ago on support recovery in 1 bit compressed sensing, where a very curious open problem remains even after some serious attempts. Support recovery with few false positives can be done with (sparsity)^1.5 measurements. Is that optimal? youtube.com/watch?v=OndWAU…
The Tim Gowers event at Cambridge concluded with a thought-provoking talk by Terry Tao on the proof of the Polynomial Freiman–Ruzsa conjecture and its formalisation in Lean. By the end, it seemed the entire audience pondered whether maths as we know it is about to change forever.
In my 2017 survey I wrote on how essentially all our post quantum public key crypto eggs are in the lattice basket. (No, I don’t know if those eggs are now broken.) eprint.iacr.org/2017/365
TCS for all workshop (and a few more words about Avi). windowsontheory.org/2024/04/11/avi…
Big congratulations to Avi Wigderson of IAS Princeton for winning the Turing Award in CS. Truly an all-time great in theoretical computer science and discrete math. Also one of the nicest human beings I know --friend and mentor to so many (including me) tinyurl.com/fz5vxxaf
Avi Wigderson revolutionized our understanding of randomness in computing, discovered unexpected connections between fields of mathematics and computer science, and is also an amazing mentor and friend. Thrilled that he has won the 2023 Turing award. awards.acm.org/about/2023-tur…
We also find a generalization of long chain derivations to adaptive non-linear 3-LCCs and obtain a super polynomial (improving on the prior cubic LB) lower bound. This LB is still long ways off from the exp(sqrt k) upper bound achieved by RM codes.

“Zionists don’t deserve to live.” Meet Khymani James, a leader of Columbia University’s anti-Israel Gaza Solidarity Encampment. He said this during a live-stream which included a meeting with the school over threatening social media posts. My latest:
Last year, we secured the release of Abigail, a 4-year-old who was being held by Hamas. She’s remarkable and recovering from unspeakable trauma. Our time together yesterday was a reminder of the work we have in front of us to secure the release of all remaining hostages.

@lionel_trolling @SamAdlerBell Nobody cares what I think but to me the "hey what's a little light antisemitism between friends" attitude, which does seem fairly widespread in contemporary progressive politics, is actually pretty troubling.
Thanks Tom :) Lots of nice questions remain here: 1. Do the weakest form of HDX satisfy Chernoff? We only prove sub-exponential concentration in this regime 2. Can we build *sparse* agreement testers with optimal soundness? 3. Can we use these tools to construct better PCPs?
A beautiful new paper on the arXiv by Yotam Dikstein @MHop_Theory, showing Chernoff bounds and reverse hypercontractivity on high-dimensional expanders! As one can imagine, these tools have many interesting applications, which they indeed discuss. arxiv.org/abs/2404.10961…
Here's what happened, in @TheFP: "But last night, sitting in the hospital, I couldn’t help but think of my mother, Shahnaz, who grew up in Iran. Her neighbors threw rocks at her for being a Jew. She has a scar on her eyelid to this day." thefp.com/p/i-was-stabbe…
To echo Boaz's point, it's crucial to prioritize empathy towards humans (independent of race, gender, religion, etc) rather than governments.
It is a shame that in the U.S. it seems you have to choose between 100% support for Israel’s actions in Gaza or opposing its very existence. If there was a demonstration against Israel’s government where Zionists are welcome, I might have joined it.
Chen’s paper has a bug, independently discovered by Hongxun Weng and Thomas Vidick, that he doesn’t know how to fix. If I understand correctly, in its current form the paper doesn’t yield any improvement on prior algorithms. eprint.iacr.org/2024/555
Is lattice-based cryptography still (potentially) post-quantum now? 🥳 Update to #eprint555 by Yilei Chen
The co discoverer of the bug in Chen’s paper is second year Berkeley grad student Hongxun Wu @HongxunWu ( whxwhx.github.io ). Quite impressive given several lattice experts looked at the paper closely! Sorry for misspelling the name in a late night tweet yesterday.
