  • I would think all the incidents with fracking have shown rock not to be as impermeable as one would expect or want. Doing this and not causing huge issues seems very hard to me. And also very situational, which is a big problem pumped hydro has.

    Pumped hydro works really well and is just about as efficient as we can realistically do, but you need to have the right circumstances. Like a biggish elevation difference, a place to store enough water at the top and bottom for it to be worth while and a connection in between to pump through and take out the energy in the other direction. Plus close enough to a place that needs the power not to be killed by transport losses.

    This thing seems to require the perfect conditions as well, which may prove even harder to find compared to places for pumped hydro.


  • An LLM cannot be anything other than a bullshit machine. It just guesses at what the next word would likely be. And because it’s trained on source data that contains truths as well as non truths, by chance sometimes what comes out is true. But it doesn’t “know” what is true and what isn’t.

    No matter what they try to do, this won’t change. And is one of the main reasons the LLM path will never lead to AGI, although parts of what makes up an LLM could possibly be used inside something that gets to the AGI level.



  • She did a follow-up on this on a recent Q&A with Adam Savage. She doesn’t use it at all, because her stump is too small. This means she has almost no leverage and strength in the stump. She said she likes the aesthetics but it’s not practical.

    Imho she needs something with like a servo assist or something hydraulic. But that means stuff like a power supply, pump, sensor, controller, plumbing etc. It would get messy fast for something that’s on your hand. If it’s more of the hand it could make sense, but the loss of only the little finger probably has almost zero impact on the use of the hand.

    Just so you know, operating spinning drives this way is a bad idea. If the platters are spinning and the drive tips over, the rotation of the drives resists the movement. This gyroscopic force is enough for the platters to touch the heads which are flying a tiny distance above the platter. Obviously this is a bad thing and will damage the drives.

    A quick fix is to just lay them flat or fix both of them together so they have a more stable base to stand on. Putting it in an enclosure is even better.













  • Many providers have specific clauses for this. Ever since crypto mining became a thing providers have included in general terms you can’t over use the service. And often specifically against using it for crypto mining.

    Providers will normally warn users and only kick them off when no explanation is forthcoming.

    Usually this applies to shared services, like a VPS. You pay a lower price because you share hardware. But that only works if the hardware is shared fairly. If another user hogs all the resources, the service is no good for anyone. But it can also apply to seemingly dedicated services, like your own server for example. In that case the server is free to be used for whatever, but things like cooling and power are still shared. A regular dedicated server service will be based on typical use and can kick users out who require too much cooling or power. In cases where the resources are legitimately required, they will offer contracts that allow you to use all of the resources all of the time. But in turn you will have to pay a premium for something like that.

    On the surface it may seem like a bit of bullshit, but that’s often what allows prices to be as low as they are. So I’m fine with it, as long as it’s made clear beforehand (which in my experience it is)
