This year’s Advent of Code has been brutal (compare the stats of 2023 with that of 2022, especially day 1 part 1 vs. day 1 part 2). It included a problem to solve with dynamic programming as soon as day 12, which discouraged some people I know. This specific problem was particularly gnarly for Advent of Code, with multiple special cases to take into account, making it basically intractable if you
Make Something WonderfulSteve Jobs in his own wordsThere’s lots of ways to be, as a person. And some people express their deep appreciation in different ways. But one of the ways that I believe people express their appreciation to the rest of humanity is to make something wonderful and put it out there. And you never meet the people. You never shake their hands. You never hear their story or tell

Math — Susan Rigetti
So You Want to Study Mathematics… IntroductionMarch 6th, 2022 Back in 2016, I typed up a little guide to studying physics called “So You Want to Learn Physics.” It ended up being pretty popular, so I started working on other guides, including a guide to studying philosophy (“So You Want to Study Philosophy”), which I published in 2021, and this long-awaited guide to studying mathematics, which I a

This page collects ISW and CTP's updates on the conflict in Ukraine. In late February 2022, ISW began publishing daily synthetic products covering key events related to renewed Russian aggression against Ukraine. These Ukraine Conflict Updates replaced ISW’s previous “Indicators and Thresholds for Russian Military Operations in Ukraine and/or Belarus,” which we maintained from November 12, 2021, t

The Blog of Scott Aaronson If you take nothing else from this blog: quantum computers won't solve hard problems instantly by just trying all solutions in parallel. You’ve seen the stories—in the Financial Times, Technology Review, CNET, Facebook, Reddit, Twitter, or elsewhere—saying that a group at Google has now achieved quantum computational supremacy with a 53-qubit superconducting device. Whil
In this roundtable, which grew out of a conference on maritime strategy in the Indo-Pacific region sponsored jointly by the United States Naval War College, the Japan Maritime Self-Defense Forces Maritime Command and Staff College, and the Sasakawa Peace Foundation, our contributors examine growing Japanese defense capabilities and aspirations. The authors examine the impact of a more robust Japan
My previous article on how the kernel decompresses generated a lot of traffic and commentary, much to my surprise. I suppose that this may be because musings of this kind fill the same niche as the original Lions' Commentary on UNIX 6th Edition, with Source Code which was a major hit in the late 1970s. Operating system developers simply like to read expanded code comments, which is what this is. W
