I don't actually post much tech stuff here, the vibes here are semi-filtered Carl and I'm into a lot of stuff. I signal boost what I think is important, I post mundanities of life, I halfheartedly promote my work, and I post very inconsistently. @reactiflux.com and @tmir.reactiflux.com are tech alts
All crypto ecosystems suffer from people who think that the cryptography enabling “zero trust” also means that social trust has no value anymore, which leads to a kind of endemic hostility. For all the chatter about DAOs and decentralized compute and the future of online community,

it's actually really annoying because I started chasing down this thought, combined with my experience trying to operate @reactiflux.com, and did some research into what projects looked like they were trying to address it. oops it's sama again, with some cryptocurrency-biometrics bs world.org

When software developers tout a tool as “flexible” so one can “set it up any way you want”, experience has taught me that it will require a lot of setup effort to make it useful at all … and it will turn out that one cannot in fact set it up the way •I• want

The fact that you can't look at the code in Next.js and understand the execution context it's running in is like deeply antithetical to the model of programming that React is built upon

Self-examination nothing: y'all need to confront the fact that you owe your academic career to the unique expertise of librarians and archivists.
Who do you think organized those LIBRARIES of texts that you're drawing upon?

the problem with relying on billionaire philanthropy instead of taxes for public good is that there are a lot more examples of philanthropists deciding the best public good rhymes with eugenics than public health or infrastructure

Important, exciting research — air pollution dropped 22% in NYC's congestion relief zone within the first 6 months of #CongestionPricing (with reductions in the surrounding neighborhoods, too)
Cleaner air, better transit, great data — all thanks to #CongestionPricing!

It turns out that fitness trackers and other quasi-medical devices have the same problem that Amy Orben and I wrote about in Science earlier this year:
Companies develop & deploy new products faster than science can help markets correct for bad products.

I do want to note Mamdani's transition specifically calling attention to like, people applying for city jobs and how many CVs they got in the mail, etc, because when was the last time you saw a politician actually talk about expanding state capacity other than hiring more cops?
