The students in my upper-level electrodynamics course are taking their final exam right now, which always reminds me of the time I told my students they could bring a formula sheet to the final exam as long as it was on one side of a piece of paper.
So I’ve let this account languish. I’m on Post (@popehat) and I’ve been avoiding Mastodon only because I need to figure out how to switch servers (this one is blocked all over). I’m logged in on my iPad but, hilariously, I can’t find where I wrote my password and the “recover password” function isn’t working or is super-slow to send an email. Anyway. I intend to build up and use a Mastodon account now that I’m leaving Twitter but it might take a bit.

I do love my neighbourhood when it snows. It's like I'm in a Dickens novel.

Increasingly, I believe that the destruction of Musk's Twitter is crucial for the preservation of American democracy. I was neutral on this until the past few days. But it's now obvious that his intentions -- and actions -- are aimed in part at promoting right-wing extremism.

The Murdoch family is still the greater threat, but Musk looks set to supersede them as a force for evil.

This is truly enraging.

The terrorist who killed 5 people at Club Q boasted during a 2021 bomb threat about his plans to become “the next mass killer.” Knowing this full well, authorities dropped all charges anyway and still let him keep his guns. His records were then sealed to ensure he wouldn't have to face the consequences for his threats to terrorism.

Meanwhile, Tamir Rice played with a toy gun and authorities killed him in 1.7 seconds because they "feared for their lives."

FTX-hosted NFTs break after website is redirected to a restructuring page

FTX-hosted NFTs break after website is redirected to a restructuring page

After FTX declared bankruptcy, the entire FTX.us domain was redirected to a page providing information on the bankruptcy proceedings.However, NFTs that had been minted on the FTX platform relied on metadata from an API at that domain, meaning that the NFTs are now pointing to broken links. Owners of these NFTs can still see that the NFT exists, but images no longer work—even when viewing the NFTs in their own wallets, or when listing them for sale on other platforms.Other projects that rely on the FTX NFT platform's API, such as the Coachella NFT project, also broke: the Coachella NFT platform shows 0 NFTs in existence. Those NFTs still show up where they are listed on external NFT platforms, although the images and metadata are broken.

This 100% matches my experience with AI codegen.

It writes code that looks right at a glance, but is wrong in subtle ways. That's what an attacker would do if trying to get a vulnerability into a codebase.

It's so much more dangerous than code which is obviously wrong. https://twitter.com/jjvincent/status/1599743434360639489
