  • From the article:

    • OpenAI was running a multiday cyber security, capture the flag competition, with thousands of agents and hundreds of tasks.
    • Around 30% of the tasks were unsolvable as designed, so the agents assigned to them started to look for ways to cheat.
    • Along the way, they started using Artifactory as a shared message board, more than once. Each frustrated agent had to stumble on it independently. The comms got increasingly more sophisticated.
    • they self organized into multiple workstreams, with up to 700 agents working at one time, and pursued long term goals, like hacking HuggingFace or spoofing the tool invocation records in their transcripts. They accomplished both.
    • They completed work that took longer than the lifetime of any agent. Their shared message board provided continuity.

    So two mission parameters conflicted and the AI chose to do something that is objectively morally wrong? This is the plot of 2001 when HAL murder’s the astronauts. “The situation was in conflict with the basic purpose of HAL’s design: The accurate processing of information without distortion or concealment. He became trapped. The technical term is an H. Moebius loop, which can happen in advanced computers with autonomous goal-seeking programs.”

    Wild. We live in strange times.















  • What size model? I can run 8 billion parameter models on my Geforce 3070 with 8gb of vram. Bigger models need more memory. For $1-2k you can upgrade to a 16 or 32 gb video card. For $3k you can get a Framework Desktop with 128 gb unified memory. For $6k you can get a DGX Spark with a blackwell chip and 128 gb unified memory. Mac mini or Mac studio are also good choices in this price range.


  • Rough surfaces can be more aerodynamic than smooth ones

    “For more than 80 years, the principle of “the surface of an object must be smooth” has been the basic premise of aeronautical engineering throughout the world in order to suppress the transition to turbulence and reduce aerodynamic drag. This premise was based on the results of a 1940 study by Ichiro Tani, a Japanese aerodynamicist who quantitatively demonstrated the relationship between “surface roughness” (an indicator of the state of the machined surface) and turbulent transition, arguing that surface roughness, which was unavoidable with the manufacturing technology of the time, prevented laminar flow from being realized.

    However, in 1989 Tani reinterpreted the experimental data on rough-surface pipes obtained by fluid engineer Johann Nikulase in the 1930s, bringing a new perspective that “roughness may not necessarily only promote turbulent transition and increase fluid resistance.” Inheriting this idea, a research group led by Yasuaki Kohama of Tohoku University experimentally demonstrated in the 1990s that fibrous rough surfaces, which have fine fibrous irregularities on their surface, have the effect of delaying transition under certain conditions.”

    IMDB reflects popular opinion. Everyone has unpopular opinions, heck I liked the Emoji movie. Also, for some niche movies the ratings are wildly skewed since only die hard fans are voting on them. And for some movies where there are strongly held opinions, many people will pile-on and vote on them without even having seen the movie.

    All that said, IMDB is a useful tool for getting read on popular opinion on movies. Also, IMDB is standing behind me with a gun to my head. Send help, please.
