Really good post (on x unfortunately) on the complexity of securing frontier AI training and why "just secure your sandbox dude" critiques aren't very thoughtful. x.com/joedaroo/status/210433592…
Quote from “Its not just the f*cking sandbox”: So all this to say: when AI researchers are nervous about things going wrong, some part of it is because there are so many variables in this complex system. So if you’re training a frontier model, you need to think about all of this. You need to think about how to keep the model isolated in this very complex environment while still retaining tool access, internet access (if applicable to the task), etc. On top of that, you need to ask: how do I monitor and understand what the model is doing in potentially thousands of parallel environments? And how do I kill a trajectory when something has gone wrong?

Working on improving the design of highlights/margin notes in @skyreader.app . Now puts community notes in the left margin and your notes to the right. More clear when your notes are private vs published to @margin.at

New in @skyreader.app: links from the people you follow on Bluesky! Similar to Nuzzel (rip) and the excellent @sill.social, Skyreader can now read your Bluesky timeline and find the links people you follow are sharing so you can read cool things without spending all your time on the timeline.

**NEW ATPROTO SPACES APP ALERT** I hate scheduling with other people. I have a lot of calendars, and i'm always searching for the right tools, but scheduling tools disappear out from under us all the time. It's infuriating. So I built intandem.space so I could run my 1-1 appointments on protocol.👇🏽

Excellent insight from @garbageday.email www.garbageday.email/p/microdrama...
Screenshot of the article with the highlighted quote: "Big Tech wants you to commit suicide so they don’t have to spend the money to kill you. They want you to forget everything you know about making a product, building an audience, and governing a state and trust that their metrics can help you do it better than them. And they want you to blindly follow those metrics until you become so “popular” on the platforms they own and irrelevant in real life that when you finally get replaced with their AI no one even notices."
