  • It’s not a million miles away, but it’s still got some problems. The ‘extract archive’ functionality seems to do it for me; think it must be wanting to pop up a (nested?) file chooser, but causes a session crash.

    Cinnamon legacy for getting work done, and KDE wayland for playing games, for me. Nice to go 100% cinnamon though, for sure.

    … and it’s been doing it for long enough that it, and all the other plutinos, have settled into a 2:3 resonant orbit with Neptune, which takes 165 years to orbit the sun by itself.

    Space is really big and the timescales are really long, in a way which doesn’t really make sense on human scales, except for things which are so fast that they also don’t make sense on human scales, like core-collapse supernovas.

    The good news is that we’re good at doing maths and we’ve built some big computers to do that maths, so we’ve no problems ‘popping a few zeros’ into the sums that we do.


  • I understand that things have changed a bit since I first moved over to Linux - moving from Red Hat Linux to Ubuntu ‘Warty Warthog’ was such a revelation in overall user-friendliness and usability, back in the day. But upgrading my graphics card from an NVidia one to an AMD was a similar change. I might have only just installed the base operating system and a desktop environment and haven’t got around to a web browser yet, but I’ve already got full hardware accelerated graphics - that’s crazy.

    Most distros now make the NVidia drivers a complete non-issue, I think? My 6600XT is requiring just a few too many compromises on new games, so I’ll need something new too, sooner or later. I used to hold off on graphics cards updates until I could get something twice as good so that it was a noticeable upgrade, but I could buy a pretty decent second-hand car for all the ones which are ‘twice as good’ now.

    An upgrade from a 1050 Ti shouldn’t be such a problem. Well done on keeping it alive so long - I had a GeForce GTX 970 that would have been a similar age, but it let out its magic smoke years ago.



  • Indeed - most Java IDEs have FernFlower built in, so it’s dead easy.

    Decompiled Java is surprisingly close to the original, especially compared to eg. decompiled C++; good luck with that. You get all the class, function and variable names back on the original line numbers.

    What you do not get back is any comments. So you can see what and how, but not why. Admittedly, most comments are kind of useless and do not explain ‘why’ very well, but for weird-but-critical code they can be essential.


  • Indeed - I’ve seen more people recommend Hannah Montana Linux (apt-based) than any of those for newcomers recently.

    You are entirely right that a Linux distribution is really just its package manager, the default packages installed, and some remote repositories which may (or may not) have had some customisation applied, which will have been pulled and built from a source repository somewhere. All that’s really needed to swap between eg. Arch, Manjaro or Cachy is to update the repo files and issue a package manager update command, although I’d probably like to verify my backups and get a stiff drink first.

    The House of Linux is built out of bricks, and the bricks aren’t that scary - you can take them to bits and look at them if you like, they’re usually zipped-up folders of text files and the binaries you’d get from compiling them yourself. But if that’s not what you’re used to, then yeah - 🤯 .

    In all seriousness, I wish that most distros had art half as good as what Void Linux has - got some really gifted people, there.



  • True, but network effects are important to that.

    There were huge numbers of people that wouldn’t move to Linux because it didn’t support all of their games. Now it does, and lots of people are moving.

    There are lots of people that won’t move to Linux because they have a random bit of hardware that’s not supported, or a highly-specific bit of software they need to do their job that only runs on Windows. The manufacturers wouldn’t support Linux because not enough people used it. Ah, but now we have all the gamers, so there are quite a lot of people using it.

    Each domino that falls encourages the rest. Steam Linux users are more than 3x Steam macOS users, and we’re not that far from overtaking it for general desktop usage. In some regions, that’s already the case, and while the Windows 10 exodus can move to Linux easily, they’d need to buy new hardware fo use the Mac operating system. Not many companies would question providing Apple support; once Linux has a comparable share, it would be foolish to leave that out of consideration as well.




  • Really, it’s a misuse of language to describe elementary particles as having ‘wave/particle duality’. If you ask them a wave-like question, they give a wave-like answer. If you ask them a particle-like question, they give a particle-like answer. But that doesn’t mean they’re a combination of the two; just means that our everyday understanding of big things isn’t suitable for describing small things.

    We know that general relativity and quantum dynamics can’t be quite right. They have enormous predictive power, but they don’t overlap, which means we can’t model things where they’re equally important; the big bang and black holes for instance. “Higher dimensions” is the string theory way of trying to reconcile them - it might be right. But a theory isn’t scientific if it doesn’t make predictions you can test, and string theory hasn’t been very productive in that so far. Amazing maths though, has been great for expanding our knowledge there.




  • Moved my father-in-law from Windows 10 to Mint.

    Biggest problem was all his ‘documents’, which were office365 web links rather than ‘actual documents’. Linux presents them as the urls that they really are. They open just fine, though, and can be exported as real local docs for libreoffice etc.

    Security and privacy were the main selling points for him. He’d done some reading and thought that Mint was among the best choices for a newstart that just want everything to work; no interests in playing games or anything. I agreed that was the most solid choice. I use Arch btw myself, but wouldn’t recommend that for beginners.

    Speaking as someone with a chemical engineering degree and twenty years in industry:

    • we have some really complicated computer programs and simulations for all the important stuff, then we add ten percent for safety and round it up to the next standard size. We don’t buy 292 mm pipe, we just use 300 mm, because that’s what’s on the shelves.

    • you need to be able to decide quickly whether results you’re seeing are sensible, usually to order-of-magnitude, and whether eg. it will take an hour to fill a tank, or a week. We usually don’t care whether it’s 55 minutes or 56. You need to be able to do those sums in your head, though.

    3 is more than accurate enough as an engineering approximation for pi. In fact, 5 is close enough, and much easier to work with.




  • There’s no committee that approves words being added to the English language. Anything that’s understood by the group that uses it is a real word. We make up new words and change the definition of old ones all the time; dictionaries are descriptive, not proscriptive.

    That doesn’t stop the concept of ‘agentic AI’ being a pile of bullshit being peddled by snake-oil salesmen, of course, but you don’t have to be Shakespeare to be permitted to make up new words.
