i used to joke that the solution to the housing crisis is to make home prices lower but keep home values high, but slowly realized that's what a lot of the financial engineering is actually trying to do.

i'm starting to get effect.website pilled. started to add some to the @val.town codebase. loving that it's one big dependency with a common style & maintainers. doesn't seem that much more cryptic than neverthrow in practice. discovered one bug so far, in datetime parsing, but robust otherwise.

I'm working on a new kind of computer. It's called the Radiant.

I've been dissatisfied with the state of personal computing for many years now, so it's time I did something about it.

If you think computers could be so much better than what they are, this is for you.

what the new york times has lacked in understanding voter sentiment this election, it has made up for in repeatedly interviewing one of the four founders of warby parker about how much he doesn't like mamdani

hyperlocal brooklyn news: the intersection of Willoughby and Duffield is finally getting fixed! crosswalk signals installed yesterday. Used to net an unmarked crosswalk that drivers would speed through. Good stuff!

the ex-palantir blog posts about how "oh boy, there are moral grey areas but we were just building technology and we didn't do the very bad things" are aging like milk, sorry folks you're the baddies, treat the rest of your career as penance

NEW: Common Crawl, the massive archiver of the web, has gotten cozy with AI companies and is providing paywalled articles for training data. They’re also lying to publishers who have asked for material to be removed. “The robots are people too,” CC’s exec director told us when we asked about this.

Common Crawl claims to provide a public benefit, but it lies to publishers about its activities.

this has to be coupled with the things that *don’t* count as a scandal: an array of harassment allegations, covering up Covid deaths, staying in a race after losing the primary, etc.
i cannot believe that “mamdani calls a close adult relative an ‘aunt’ even if they are not literally their parent’s sister” is what counts as a “scandal” these days

prediction markets really ended up being one of those 'interesting in theory but shit in practice' kind of things, they're legal and popular now but basically an outgrowth of gambling addictions and are absolute political cesspools
