    Your computer is a bunch of parts that need software to make them work. The “operating system” handles talking to the hardware directly, while the programs you run only talk to the operating system. Talking to the operating system is easy, talking to the hardware is difficult, since you may need to speak a hundred different languages to work with every possible network card, sound card, graphics card, etc.

    The operating systems you have probably heard of are windows and macOS. Linux is a 3rd one.

    Windows is owned by Microsoft, macOS is owned by Apple, and Linux is developed by the community and (typically) released for free. Since anyone can work on Linux, there are tons of different versions of it floating around, that are all slightly different from one another.



  • But AMD has been making leaps and bounds improving their GPU software

    They are still largely shitting the bed here. Their ROCm installer won’t run on Ubuntu 25.04 last time I checked, and the 9070xt won’t work on OSs that ROCm DOES support because the kernel and graphics stack is too old.

    ROCm has been “almost ready” to be a drop-in replacement for CUDA for almost a decade. I feel like it literally would take nvidia ceasing to exist to give them the critical mass to push it over the finish line

    Half of them haven’t been active in 2025, and the first active member i clicked on’s commit history is “fixed a typo on the website” once this year, and once 6 months ago

    It’s a shit metric because people spam OSS repos with “minor text fixes” pull requests so they can slap “inkscape contributor” on their CV.



  • We’re at a point where it’s no longer profitable for individual miners

    We have been at that point since GPU mining stopped being feasible in 2014, it’s just gotten worse. ASICs made it so the only people who could profit off mining were people who could place a wholesale sized order of hardware from bitmain, etc. Anyone else who claimed to be mining profitably was likely someone who was:

    1. buying old hardware 2nd hand (or new hardware at MSRP) and capitalizing on free electricity in their rental
    2. not selling their Bitcoin immediately (they weren’t making money from mining, they were making it from speculating)
    3. lived in Quebec and could double dip (North America’s cheapest grid + free heating for 8 months of the year)

    unless there’s a radical change in bitcoin’s algorithm

    The algorithm already does this though. Every 2016 blocks if it took more than 10 minutes per block, the difficulty of mining bitcoin goes down, not up. This is why every halving event you see a radical drop in difficulty, because at a given kWh you are producing half as many bitcoin - meaning people turned off their miners because it’s less profitable. The flipside is the rate of issuance goes down, so there is a lower inflationary effect, and the price of Bitcoin usually also skyrockets (which means eventually these miners re-enter, and difficulty eventually goes back to where it was). It can never get to a point where Bitcoin mining is completely unprofitable unless the price goes to zero, because there will always be a guy with a solar panel and fully paid-off hardware who can mine it for free. Granted, it can get to a point where a lot of people have to take a huge loss on capital expenditures if the price nosedives and never recovers
