    I highly doubt it's an SQLite bug, considering how thoroughly they test their code to behave correctly as long as their assumptions are filled. And those assumptions are clearly vi…

    Comment #44681271

    I wouldn't recommend SQLite on ZFS (or in general for other reasons), for the precise reason that it either lags or is unsafe. I've encountered this bug both on illumos, specifical…

    Comment #44680479

    I've not observed other databases locking up on ZFS, Postgres and MySQL both function just fine, without needing to modify any settings.

    As noted in a sibling comment, this causes corruption on power failure.

    Comment #44680191

    Disabling sync corrupts SQLite databases on powerloss, I've personally experienced this following disabling sync because it causes SQLite to hang. You cannot have SQLite keep your …

    Comment #44674547

    SQLite on ZFS needs the Fsync behaviour to be off, otherwise SQLite will randomly hang the application as the fsync will wait for the txg to commit. This can take a minute or two, …

    Comment #44674532

    ZFS isn’t viable for SQLite unless you turn off fsync’s in ZFS, because otherwise you will have the same experience I had for years; SQLite may randomly hang for up to a few minute…

    The output power of a rocket is different than a blow torch. The sound pressure alone is near or above atmospheric pressure. That concrete is being exposed to vacuum and more than …

    Comment #34969002

    You're still referring to two distinct properties with Angular Moment being one and Spin being the other. Because a black hole can in fact orbit things and that would give it angul…

    The commenters is probably using ChatGPT to compose the reply, it's notorious for mathematical mistakes.

    Comment #34966709

    Spin and Angular momentum are two very different things. Angular momentum measures the velocity of a black hole in, eg, an orbit. Spin measures the rotation of a black hole against…

    Comment #34957711

    There is a cheap and even for current humanity achievable way to rotate a black hole; change your frame of reference. That is not only true for angular momentum but linear momentum…

    Comment #34957363

    The spin axis isn't a valuable reference since it depends on your frame of reference, which is a concept that gets rather ambiguous as you get close to a black hole anyway. Plus yo…

    Maybe uutils could have a build feature that specifically turns off the prefix matching and will break stuff but allows using newer and more useful flags in exchange. I've VERY rar…

    That would be true of any software system we put into an airplane, yet we have deployed software into airplanes. If your AI has linear / continuous output, testing it should be no …

    Comment #34706931

    That much is clear but any remotely continuous AI model is very predictable.

    Comment #34706322

    That entirely depends on what exactly you implement here, it's entirely possible to implement an AI with continuous & linear properties, meaning that you can extrapolate it's behav…

    Comment #34705803

    If for a given set of inputs there is a deterministic output, then the overall behaviour to a series of inputs is just as deterministic and predictable. I'm not sure what you mean …

    The pilots take off when they take off. If their take-off clearance isn't obviously time limited, they are certainly allowed to take their time. If they rush the take-off they migh…

    AI is entirely deterministic. ChatGPT and StableDiffusion and friends are fed endless amounts of random seeds along with every input to keep them from just saying always the same t…

    The tape under the turing machine is infinite, so it's certainly not limited to 47M states. The conjecture states that all machines that halt will do so within 47M states.

    The Pi's will be using those 200Watts at near full tilt. The main use here would be larger computational tasks that you can easily split up among the blades. Or you run a very hard…

    Comment #34501925

    I can still get SQLite to trivially corrupt indexes and table data by running it on top of NFS and dropping the network. I wouldn't put much money on this statement on their websit…

    The 1U server is however likely to use more than 200 Watts of power that the 40 Blade 2U setup would use.
