@jackemled@furry.engineer Any OS that can’t extract from the background activity of a 2011-era laptop enough entropy to initialize its RNG within a few seconds is broken. Possibly the system is making an overly-conservative assessment based on portability to some worst-case embedded hardware scenario.

A friend pleaded with me to try some vibe coding tool. Said I would fall behind, etc. “It’s sandboxed,” they said. “It can’t access any files except those you approve on a case-by-case basis.” Against my better judgement, I installed it. It required (lol) node and npm. Sigh. In for a penny and all that. I start the tool and get a nice prompt. I ask it where it’s running. It tells me it’s running locally. I ask it to run a basic check of my nvidia drivers and toolchain. Does a respectable job. Then I ask it more about its runtime configuration. Now it admits that it’s running in some unknown data center. “Who’s paying for this, and why?” I wonder. I request a directory listing. An out-of-band-looking UI control appears politely asking permission to read the contents of the project directory. Wonderful! Warm fuzzies wash over to see a purposeful and ergonomic sandbox in action. Friends, this “sandbox” is a lie. A scam. A total fraud. The AI has unrestricted bash shell access.

Replying to on assemblag.es

@CyberneticForests@assemblag.es To me a simpler framing is:

  • An optimization goal function created a perverse incentive.
  • The model under test exhibited unexpected (but not unprecedented) behavior by escaping the test sandbox
  • Hugging Face was a bystander, were harmed, and filed a police report.
  • These events may support some of OpenAI’s preferred narratives, but seem to go against others. On the whole OpenAI suffered mild reputational damage.
  • This was not a conspiracy, a marketing stunt, or planned in advance.

If you repeatedly post pictures of rxpists or have an animated icon, I’m probably muting you. Nothing personal. It’s just this app doesn’t allow me to manage these things. The platform doesn’t allow posting a link without the server automatically grabbing some photo (eg promotional photos of the rxpists in question) from the linked website and displaying it full sized on the user’s device. The developers have long known about this and said that they would do something about it, but things seem to be moving the other direction. They have since *removed* the ability to copy links rather than opening them directly, which I relied upon to exercise a tiny bit of control over my web privacy.
