  • Depends how familiar with disk partitioning you already are, but it’s generally not that bad. Shrink your windows partition, create a new ntfs partition in windows, and install Linux. Pretty much every major installer has an option to preserve Windows.

    I guess this is the thing with Linux, at various levels it skews DIY and more time intense. And honestly the market seems to be bifurcating between that and the opposite extreme: Android/iOS, which many use as their main PCs now.








  • It’s ironic how conservative the spending actually is.

    Awesome ML papers and ideas come out every week. Low power training/inference optimizations, fundamental changes in the math like bitnet, new attention mechanisms, cool tools to make models more controllable and steerable and grounded. This is all getting funded, right?

    No.

    Universities and such are seeding and putting out all this research, but the big model trainers holding the purse strings/GPU clusters are not using them. They just keep releasing very similar, mostly bog standard transformers models over and over again, bar a tiny expense for a little experiment here and there. In other words, it’s full corporate: tiny, guaranteed incremental improvements without changing much, and no sharing with each other. It’s hilariously inefficient. And it relies on lies and jawboning from people like Sam Altman.

    Deepseek is what happens when a company is smart but resource constrained. An order of magnitude more efficient, and even their architecture was very conservative.

    Meanwhile, Rust punches you in the face for the mere suggestion. Again. And again.

    Python happily nods, runs it one page at a time, very slowly, randomly handing things off to a C person standing to the side, then returns a long poem. You wanted a number.

    Assembly does no checking, and reality around you tears from an access violation.

    EDIT: Oh, and the CUDA/PyTorch person is holding a vacuum sucking money from your wallet, with a long hose running to Jensen Huang’s kitchen.

    I had to think about it too, lol. This is an equation for DC/instantaneous power, and if you want to get into AC math, this is more like a square wave. Averaging the power out over time doesn’t necessarily work with the equation, as you figured out, as it doesn’t when you try to measure AC (sinusoidal) power by average voltage or whatever.



  • Shoudn’t it be 25%?

    Current is not controlled here, resistance (aka the soldering iron) and voltage are.

    Power = Voltage ^ 2 / Resistance. Double the voltage, that quadruples the power. So you only want to plug in 25% of the time to get the equivalent power of 120V.

    But it might not melt at double power? Maybe the extra heat helps, I can’t find a resistance/temperature curve for a soldering iron…
