If you're talking about uranium enrichment, that's like saying we increased the amount of gasoline on earth (by refining crude oil). Natural uranium is ~99% non-fissile, and ~1% fissile, and we're only removing part of the non-fissile isotope to obtain 5% concentration of the fissile isotope. Uranium still needs to be mined, spent fuel can be partially recycled, but you need some new natural uranium input in the end. That said, non-renewability of uranium is a non-issue IMO, compared to the huge amounts of other non-renewable resources we're extracting.
> Isn't pumped hydro severely limited by geography in many places?
Scotland seems to be a perfect place for pumped storage. I see that UK has 4 pumped storage stations, 2 in Wales, 2 in Scotland. But Scotland being quite far from most of UK's population may not be ideal if we're talking about supporting the whole country with pumped storage. It would be like 600km to the south of England.
Yeah, the idea of people claiming that something on the Great Britain is too far and can't distribute power to something else on the Great Britain is laughable.
Next we'll have somebody from Lichtenstein saying the same about their country...
Well, I only said that if we're considering a ~fully renewable energy generation in the UK, with supply evened out by massive pumped storage projects, then locating all the storage in Scotland isn't ideal for the efficiency of the system. But yeah, I looked up the losses on HVDC lines, and it seems to be a non-issue (at least from a technical point of view). I also looked at a map of wind power[0] - seems concentrated on Scotland, so the distance from generation to potential storage would be quite short.
The thing is, it's nowhere near 90% in general. 90% is the generation right now, with sunlight and good wind. On the site you can see that renewables were 66% in the last 24h, 46% in the last week, and 42% in the last year. I don't think it's possible to have 90% renewable generation overall without massive energy storage.
The title may be misleading, but IMO not for the reasons you mentioned. "90%" is based on generation right now, live. On the site from the post you can see that for the last day (24h) renewable generation was 66%, for the last week 46%, for the last year 42%. So it's nowhere near 90% renewable in general, but it is 90% at the moment (there's sunlight and good wind). Emissions on the website from the post are lower than on the website you linked - 107 g/kWh for the week, 124 for the year - but I don't know why that is.
Crash probably a couple seconds later, wouldn't rely on the video for the exact timing.
So it seems that ATC made an error by allowing the truck to cross, and then the order to stop wasn't communicated clearly enough. I wouldn't place much blame on the truck.
Edit: Looking at some other videos with that audio, I'm also not sure if the video I linked represents the time between communications correctly, transmission at 3:15 may have been right after the one at 3:02. Anyway, the best thing is to wait for the investigation.
IMO putting an important number in your post/comment, and not providing a source for that number, is also kind of low effort. If you verified the number before writing, you already had the source ready and you could just put it in the comment. If you wrote the number from memory, not checking if your memory is correct is low effort (but you can also warn the readers that the number is from memory, that's better). If you're intentionally misrepresenting what the number means in your comment (and giving the source would contradict the meaning of your comment), or just giving a number that "feels right" or a number that you know is wrong, then it's low effort and a lie.
I try to verify important numbers and facts in what I read, and seriously, there's so much fake or misrepresented info everywhere, on every political side, that it's depressing, and it makes me don't believe literally anything without a source, unless I verify it myself. Of course when someone provides a source, I often look into the source, and sometimes it turns out that the text misinterpreted/misrepresented the meaning of the source. On Wikipedia, I also check if what is written is actually in the source, because sometimes the editor writes his own opinion while only loosely basing the text on a source (or basing it on nothing).
Verification can take some time, and that's the effort passed from the author of unsourced claim to its many readers, unless they just trust it or ignore the claim.
When I write anything I try to include sources for important things. If I wouldn't include a source, and someone asked "Source?" I wouldn't think "what an annoying guy", I'd think "oh, I could have linked that in the first place". And I usually upvote "Source?" comments (unless it's a thing that anyone can check in 30 seconds). I usually double-check the facts in what I'm writing, and many times I almost wrote something from memory that wasn't true, but looking for a source saved me from that.
I haven't used them, but IIRC they maintain a constant voltage until they're discharged, when it instantly drops to 0. That may be a problem, because if your device has any battery indicator, it will show the battery as full until the end. Nothing will tell you that you need to replace the battery before the device powers off. That's why I decided not to buy them. My mouse knows when my alkaline AA battery is low and gives me a warning.
I use rechargeable CR123 batteries in my August smart lock that face this issue. The solution is to have a spare set and rotate/charge on a fixed schedule before they die. I have a quarterly calendar reminder to do so.
If you're not sure if there are any important world-writable files, then just check that? On Linux you can do something like "find . -perm /o=w". And you can easily make whole dirs inaccessible to other users (chmod o-x). It's only a problem if you're a developer who doesn't know how to check and set file permissions. Then I wouldn't advise running any commands given by an AI.
Careful, you’re talking to developers now. Chmod is for wizards, Harry. One wouldn’t dream of disturbing the Linux gods with my own chmod magic. /s
Yes, this is indeed the answer.
Create a fake root. Create a user. Chmod and chgrp to restrict it to that fake root. ln /bin if you need to. Let it run wild in its own crib.
Though why bother if you can just put it into a namespace? Containers can be much simpler than what all this Docker and Kubernetes shit around suggests.
How much smaller user base? Looking at some recent data, which may not be accurate (but they're required to publish user numbers in the EU at least), it looks like the user base may be only 0-20% smaller compared to 2022.
