  • Besides the first all electric train bit, which is nonsense, it also touts the capacity of the train. It has 120 seats, which may be mind blowing to car heads, but for a train is rather on the low side. Regular passenger trains often have over 200 seats and many have more seats for the same length. For busy pieces of track 600 seats per train aren’t unusual.

    It really is like the author has never heard of trains before and has his mind blown by the concept.

    Personally I think putting in batteries is kinda dumb, trains need so much infrastructure already and it’s fixed in location. Adding a power delivery system (like overhead power lines like most electric trains have) is really easy. That way a lot of weight is saved, thus making the whole thing more efficient. You also don’t need any special materials to make it, compared with huge batteries. And the wear components are a lot less expensive to replace.








  • I started with Suse 5 when it came out, as something I was interested in fucking about with. I didn’t have internet access at that time, but I did had a couple of books about it (the distro came with a book as well). It was a couple of CDs and a boot floppy disk (booting from CD wasn’t really a thing).

    I used it for years for software development and simple tasks like Word processing. Getting my printer working on the thing was a chore, as was basically anything. Especially without internet solving issues was sometimes simply impossible. My scanner simply didn’t work. Getting the desktop environment to run was very hard, I struggled with it for a long time. And once I got it working properly, I got a new videocard and it broke the whole thing again.

    The system was very painful to use, it was super cool, but almost nothing ever worked right. And trying to fix shit usually made it worse. But once you did get it working right, it was simply awesome. And the feeling of accomplishment was awesome after finally getting something right. For software development on the terminal it was pretty awesome though. Back then I did almost everything in text mode, as I was used to DOS before that. Going into Windows was something you did only sometimes with Windows 3.11 (and even 95) and I did the same in my Linux environment. The desktop environment used up a lot of memory and was pretty slow, so I preferred the console. It was only later booting into the desktop became the norm (around the Windows 98 era).

    I used Suse till version 6.1 (still have that box). I bought version 7 (still have that box as well), but never really used it.

    Back then I used Debian to create small internet routers for my friends. I got an old compact computer, put in a floppy with Debian, a couple of network cards and created small NAT boxes like that. This was before NAT routers were the norm, people just had internet on 1 machine, connected directly. But as computers became cheaper, a lot of folk had more than 1 computer in the home. With no real way to share the internet connection between the different computers. Microsoft created the Internet Connection Sharing feature, but that was pretty slow, disconnected often and ate resources on your “main” PC. So my little boxes worked great, I helped people setup a home network, connected my magic box to get every system online. Also helped them setup some port forwarding for the stuff they used.

    Because I used Debian a lot, I switched over to Debian for my main rig when Suse 7 released. Used Potato, Woody, Sarge and Etch a lot. Switched around between Debian and Ubuntu in the Lenny and Squeeze era. Have been using Ubuntu ever since, never really had a reason to switch. Debian compared to Suse was so nice, I really liked the way Debian did things. It made a lot more sense for me in my head compared to Suse.

    As I fucked around with computers a lot, I always had both Linux and DOS/Windows machines running and even had a couple of dual boot systems. For any kind of gaming DOS/Windows was required back then and I did love to game. I do think Windows 10 will be my last Microsoft OS, since Windows 11 absolutely sucks (use it at work, I hate it). Work stuff has become less and less of an issue to get stuff done on Linux just as well as on Windows. And gaming has come leaps and bounds due to the work on the Steamdeck.

    So hope to fully ditch Microsoft in the near future, even though my first ever computer in 1984 ran Microsoft firmware with Microsoft Basic being the default user interface.




  • This is pretty dumb, machine learning algorithms (fuck off with calling it AI) are especially good at seeing signs of disease in data such as xrays, CT and MRI scans. It’s the one place they really help save time and prevent mistakes. And even if it’s just to flag shit for a second opinion by a doctor and not to replace the doctor, that’s still super useful. Pattern recognition is hard and these kinds of algorithms are very good at them if provided the right source data to work off.

    If only the media and big corps would stop claiming LLMs are general AI, then maybe people would stop using them for stuff it’s clearly not good at and not meant for.


  • As someone who has worked on embedded systems for the past 30 years: It used to be a real big deal, but for the past 10-15 years it hasn’t. We now have fully fledged multi core systems running everything. Even small embedded sensors or actuation controllers are 100+ MHz microcontrollers with oodles of flash and ram.

    Now there has been an interesting turnaround with the whole chip shortage for the past years. All the young folk are at a loss, being used to just putting powerful chips all around willy-nilly. So they turn to the old folk like me to figure out designs with less chips, running busses all over and connecting dumb sensors/actuators to a central processing unit.




  • One of the most important ones is this one: https://joint-research-centre.ec.europa.eu/jrc-news-and-updates/stemming-tide-beach-litter-2018-09-25_en

    This was the basis for the decision to mandate the caps be attached to the bottles, since they found a lot of caps and less bottles. This would indicate a lot of caps get separated from their bottles, which this change should mostly fix.

    The other was an interview with this guy: https://zwerfinator.nl/ I can’t find the interview, no idea why, but he hasn’t published the results yet (no idea why, it was scheduled to be published I think, but somehow got delayed). They were saying the new pfands really helped and the number of bottle caps have gone down. But this is highly depended on the location. For example a lot of research is focused on beaches, where there is obviously often a large delay between the deposition and the collection. In city centers this time is often much shorter, so the impact of changes are seen faster.

    So sorry to disappoint, it’s too soon for a peer reviewed study diving into this. Also with all the other changes the EU has mandated on litter and single use plastics, it would be hard to quantify which implementation has what effect.

    But my thinking was: There is for me good data showing this is an issue (which I was doubting) and the solution seems solid enough. Other changes like pfands on small bottles and cans have made a big impact (research is available for this, for example https://open.overheid.nl/documenten/ronl-8b11214f23388b3395402609d76286475b4f2908/pdf). And the people doing the research say they’ve seen results that it works. So that was enough to convince me.

    If somehow the caps being attached doesn’t lead to less caps in litter, that would be a very interesting result. Without a doubt the EU would change the regulation to fix it, depending on why they think the change didn’t work. But this would not lead to the caps being like they were in the past.

    I can’t find it on mobile right now. It was a preliminary result, because the attached caps haven’t been required that long. Also most countries have implemented extra pfand systems for small plastic bottles, which also helps. So it’s tricky to say which regulation helped most.

    But there are plenty of sources of how many bottle caps there are in the streets and oceans. And how harmful they are to animals who think the small bright things are food.

    It also makes sense, instead of the bottle and the cap becoming seperate pieces of trash, it’s now a single piece. So it reduces the number of pieces if not the volume of trash.

    Also for people from the US where bottles are shredded and caps typically not recycled. In Europe the caps also don’t get recycled, but instead removed. The bottle is then checked for leaks and defects and if it passes it’s cleaned and then reused. Actually recycling plastic is hard, so this way a bottle can be used at least two or three times.

    You don’t get your pfand in many cases if the cap isn’t on, as well as the label many times. This isn’t so much needed for the recycling but important for the whole process. For example groceries are required to take in bottles, but are allowed to limit this to bottles they sell. So the barcode om the label is checked for this purpose. The label is removed in the recycling process. The cap is required to motivate people to return those and not have them turn into litter. It’s also a hygiene thing for the people handling the bottles, often there is liquid still in the bottle and without the cap it comes out during handling.

    I will find the data later when I’m on desktop.


  • Yes I hate them as well, they always get in the way and putting the cap back on is super annoying.

    However, since these bottles were introduced data has shown they work. Bottle caps were one of the most found items in trash picked up from the streets. The number of bottle caps has gone way down since these were introduced.

    So I’ve accepted them. Can’t argue with data. I’ve never returned a bottle without a cap in my life. I’ve never thrown away a cap separate from the bottle. But turns out the world is full of psychopaths who throw the cap in the street. Probably the same kind of person who throws their trash by the side of the road from their car. Fuck those people.
