that’s just unsolvedslop. you only like it because its pressing outward against the boundaries of human knowledge

Everyone knows what they say about he who fights with monsters, but I desperately need to know the fate of he who fights with robots. For a friend.

Okay so – with a big caveat that we still need to write a lot more documentation – between the @roost.tools team, @dcallies.bsky.social and myself we've managed to ship a new documentation site for ThreatExchange / HMA: facebook.github.io/ThreatExchan...

Stumbling onto Hubrid's "Cosmic Punk" album has been the first Spotify algorithm W for me in 2026.

We're announcing a new partnership with StopNCII.org to prevent non-consensual intimate imagery (NCII) from spreading on Bluesky. While NCII hasn't been frequent on our platform, these incidents are devastating for victims and preventing them is a top safety priority. 1/4

Excited to announce here at the @parispeaceforum.bsky.social that, after months of joint technical work together, OpenAI will open source through ROOST one of its main internal models that handles detection and moderation. This will allow anyone or any company to use, test, and study the model.

turns out that with facebook's pdq hashing algorithm, you can hash every image that goes through the firehose. minimal cpu required. fun stuff! then just throw pgvector on top and boom

I accidentally wandered into owning facebook/ThreatExchange and feel like an imposter, but these last few months we've had the most external contributors that I can remember. I opened #1761 with the intent of doing it myself, but before I started someone else put up a PR. I think this is good?

gotta give a shoutout to HMA (hasher-matcher-actioner, aka Open Media Match) developed by great folks like @dcallies.bsky.social that built an open source safety foundation to grow! Everyone benefits from having access to this kind of technology and a rising tide WILL lift us all.

Oh noes! All of my forms of communication share common failure points! Even WhatsApp has failed me. Wife: "Are we just going to have to shout at each other?" Me: "Yes, as the cavemen did."
