  • I just upgraded from Win10 to Debian on my primary/gaming desktop; every game I’ve played in the last 4 years in my Steam library is listed as compatible, most things I do on my computer are either a website, a game, or an application with a native Linux version or good wine compatibility.

    As a personal user who does a wide variety of things on my computer, I don’t really need Windows anymore. I’m dual booting for the time being as I configure things, but I’m quickly running out of reasons to use the old Win10 partition. And all the weird slowdowns it was exhibiting? Totally absent in Linux. I expected performance to be a wash, but it’s noticeably improved.





  • This is one of many examples of a class of problem where the technology is the easy part. There’s room to improve the tech certainly, but the technology sufficient to solve the problem is already well understood.

    The hard part is how to get people to actually do the necessary changes. To consume less, get fewer gas cars on the road, increase the amount of nuclear, hydro, solar, geothermal, and wind in the grid, and minimize coal and gas use. To reduce land use by cows, and increase land use by trees and native plants.

    But maybe AI is the secret here. We have tools that are in the hype moment whose training data already contains several reasonable solutions to climate change. Maybe if AI “finds” the solution to climate change, people will finally listen



  • The thing is business is more booming than it’s ever been, but making the line go up forever is a fool’s errand, at some point you’ll hit a peak. Hitting that peak is immensely punished in our economic system.

    If you make a hammer that’ll last 100 years, you’ll sell as many as you can reach customers who need one, before hammer sales plummet. Instead of being rewarded for making a great product, you’ll be punished when sales fall because you’ve solved a problem for most people.

    Advertising is kind of neutral in abstract in my head. Make a great product for a fair price, and let people know about it, and that’s actually probably a benefit to both parties. Make a terrible product, and tell a bunch of people it’s great, and you’ve spent resources doing them a disservice. But if you can convince them it’s good enough to spend money on it, and keep your revenue per customer above the cost to acquire them, it’s profitable. And that’s all they care about. It’s basically the same pattern as a scam, but profit is the only thing they’re told they’re allowed to care about.




  • Agreeing with this, expanding a RAID array is not necessarily impossible, with something like RAID 5, and the right RAID setup, you could theoretically add an identical disk without wiping it all in the rebuild. RAID 1, you’ll 100% need to copy the data somewhere that isn’t the 2/4 disks in the meantime. In an environment where storage is expensive, RAID 1 is not suitable imo.

    ZFS makes it so easy though. Throw a mismatched disk in? No big deal, it’s in your pool now. Want double parity for extra peace of mind? You can do that. It self-heals so you don’t need fsck, its maximum limits are too big to realistically matter on human scales, and the documentation on it is pretty good.


  • Yeah this is it, the problem is that even once you solve the technology problem, it becomes the choice between two logistics problems, distributing liquid fuel for refilling, and moving large amounts of power on the grid on demand. The latter is a solvable problem, but the former is just so well understood.

    Certainly, most people are better served by EVs today, for their personal vehicle needs. But I think hydrogen will be a compelling option for people with specific needs beyond the short term. Especially with continued investment in that technology in Japan.


  • There are two hydrogen fill stations between my home and work, they definitely get used, and the price per kg of green hydrogen is still trending downwards. It’ll never be the next big thing, hydrogen is heavy and has several of the other problems of gasoline that EVs always solve. But for people who need personal transport, and need to frequently go larger distances than one battery charge will support, hydrogen fuel cells solve a problem EVs have, without going back to fossil fuels; fuelling up takes negligible time.

    I think hydrogen cars will have a niche for a long time to come, enough to keep the technology around and evolving.
