  • Testing and validation are very important, but they’re no replacement for structurally making mistakes as impossible as possible to make in the first place. In fact, that was the conclusion from the Gimli Glider incident, that using mixed units increases the likelihood of mistakes being made, and so they stopped doing that. It’s kind of absurd to acknowledge that people make mistakes and therefore their work needs to be validated, but when the people doing the validation also make mistakes, they get all of the blame even when the people who made the thing did things in a way that increased their chances of making mistakes when they could have chosen not to.

    Also, that’s some contrived scenario you’re painting.You make it sound as though every machine shop in the US would have to replace all of their equipment. First of all, for anything computer-controlled the units are arbitrary and software-defined. But even for purely (electro-)mechanical machines, it’s not like those can’t be (and aren’t already) modded up the wazoo. Why replace the entire machine when you can just swap out some of the gears or even just the dial? If a machine has been around since 1945, they’ll have done things like that many times already.

    Of course no transition is going to be instant or painless, but it’s better than keeping up this situation forever. I mentioned two incidents because they’re the most dramatic, but things like that happen every day and the cost of lesser incidents also builds up. Somehow, almost all of the rest of the world managed to go against centuries if not millennia of tradition and momentum and transition in a fairly short amount of time during a period when precision engineering was already a thing that happened at a large scale, but the US is special? Give me a break.


  • Well, I do think that has value too. This example is going to be fairly specific to my situation, but as a programmer working on simulation software, it’s not uncommon for me to see or need to enter values in terms of meters that I think of as being in the realm of kilometers. Being able to reason more intuitively about these distances just by moving the decimal point around instead of having to multiply/divide them by 5280 or something is helpful. And the reason I have this intuition to begin with is because I use the same units in everyday life. This does require the system of units to be based on multiples of 10, however.


  • It’s not my measurements I need to convert, it’s other people’s. Don’t forget, American content is pretty overrepresented on the internet, so I actually need to do conversions pretty regularly.

    Beyond the day to day, a spacecraft has burned up in the Martian atmosphere and an aircraft has run out of fuel mid-flight because of unit conversions not being done. These happenings aren’t very common, but the repercussions can be pretty big when they do, and the fact that this is a completely self-inflicted problem just makes it worse. Also, the shipping industry spends a good amount of money on unit conversions.

    As for the problems with base-10, certainly a system based on base-12 would in principle be better (mind you, imperial isn’t one either). The problem is our numerals are base-10 and so our intuitions around numbers are based on that. 12 can still be dealt with, but once you get to 144 or 1728, it gets a lot harder. I can certainly name more integer divisors of 100 and 1000 off the top of my head despite having fewer of them.


  • I have a collapsible silicone bucket with a lid for popcorn making that goes into the microwave. It’s easy to use, doesn’t require any fat, also serves as a bowl and you can just throw it into the dishwasher. Size-wise, it’s probably not that different from an air popper when collapsed, but it’s easier to find a spot for; mine is on top of the stack of roughly bowl-shaped things. And you could also use it as a bowl for other things, so it’s not necessarily single-purpose.




  • It’s an inevitable outcome of its structure. With memes, it’s usually just the low-information image, which is typically visible from the post listing. There’s no article to read, no video to watch (or just a very short one), no question to think about, and you can upvote it straight from the post listing, so there’s not even a link to click. In other words, memes have a very low barrier-to-upvote compared to other types of posts, and as a result, are more likely to get upvotes and end up on the front page.

    For serious conversation what you really want is a forum or only join communities on Lemmy where memes are frowned upon.



  • Despite the quality of their results going down in recent years and getting worse because of AI slop, the search engines I would miss the most in terms of type of service. Most alternative search engine still use the indices of Google and/or Bing and the ones that don’t, don’t have a very big index. I’m old enough to remember a time when search engines were plentiful, but terrible, and back then I actually made use of web directories, like Yahoo! at the time, more. A still-existant example would be Curlie, an heir to dmoz, and there are also more local sites like the Dutch Startpagina. Being more dependent on things like that would probably make my web usage more exploratory and less about trying to find a specific piece of information quickly. And I would also go directly to specific websites more often when I do need specific information. But there are also a few companies working on making a European search index and this happening would undoubted accelerate their efforts, so depending on how that works out, not much might change at all.

    Streaming-wise, there are local streaming services for films and TV shows and they would undoubtedly expand their offerings with the loss of competition from American giants, but also, I never stopped buying BDs and DVDs (in fact I have a backlog). I never understood the appeal of music streaming, so I still buy music, sometimes even on CD. As for something like YouTube, Nebula is America-based, but it’s not “big tech”, so I would watch more of that. Niconico Douga isn’t what it used to be, but that might change without YouTube. And there would probably also be some movement towards federated video streaming.

    I don’t actually make use of any of the big social media platforms. Technically, I have a LinkedIn account, but I don’t really use it and wouldn’t miss it. It’s not really social media, but I do use WhatsApp, but that being gone would just make it easier to convince friends and family to switch to something better.



  • PNG does not compress photos very well. A photo that is 5 MB when saved as a high-quality JPEG may very well be at least 15 MB as a PNG. Also, a lot of cameras (phone or otherwise) save to JPEG by default.

    I do wish more people would use PNG where it makes sense, though. The other day I made an edit to an image containing line art that was purely black and white except for the compression artifacts. I applied a threshold so that all the artifacts became either perfectly black or white and saved it as a monochrome PNG, reducing the file size to less than a third, while containing more information and having a cleaner image. I later remembered that I could reduce the file size even more by using indexed colours. In other words, whoever originally saved it in a lossy format actually made it take up more space than needed while also needlessly reducing image quality.
