  • look at EV prices in china for a more accurate depiction of the battery progress that is being made

    apparently the government EV subsidy for outright purchases ended in 2022, but they’re good enough at the manufacturing now that EVs are still exceptionally cheap. 70-80% of world lithium-ion production also takes place in China, so it makes sense.

    There’s a lot of reasons that I don’t like the Chinese government, but they have been doing a whole lot better than the rest of the world with investment into the future of technology from what I’ve seen. The number of top-rated CS and EE schools in China is doing a whole lot on its own.













  • People make it sound like its some extreme time consuming task to learn rust. Rust actually gives helpful compiler errors tho and there’s a lot of resources online.

    I was able to start making some basic things in rust (like an ascii-rendered brute force n-body simulation) with the help of a few google searches after just like 2 days of messing around in my free time. I’m sure reading kernel stuff requires much more advanced knowledge than what I have but it’s really not a large barrier.

    I have a laptop with 4gb ram that i’ve been using kde plasma on and fairly frequently it just freezes or I have to restart because I had like 6 tabs open in firefox

    Although I don’t remember having that problem as much when I was on xfce, but I also might not have been using it as heavily then

    I’ve never had a similar problem with chrome on chromeos with the same amount of ram, I think chrome+chromeos might be more aggressive with unloading tabs

    Sometimes it does actually kill firefox but sometimes it just becomes very slow (1-2 seconds per frame) or freezes entirely for several minutes when out of memory. Might be just because the swap is really slow, but there’s just 2gb of that, why would it freeze for several minutes? (One time this was happening was when I was trying to compile llvm on two threads, I ended up having to temporarily kill the desktop environment to save ram)
