Indeed. Here in the UK, people can request that their water company should add it in if their water supply is low-fluoride, for instance from a reservoir, and the water company must add it in.

Back when I used to work in water, that was always the stuff that gave me nightmares. Concentrated hexafluorosilicic acid is what we'd use for dosing. We'd test all the equipment in the chemical room on plain water, drain it out and then literally brick up the doorway. Site would be evacuated during delivery - delivery guy would connect everything up in a space suit, hop in the shower afterwards. Lasted for ages and ages, since you only need the tiniest drip in the water supply to get what you need, but the tiniest drip on your skin would be enough to kill you as well; its lethal dosage is horrifically small.

Made working with all the other halides much less of a concern - we use shed loads of chlorine, but that stuff is much much less nasty in comparison.

Yeah, it's always had really strong art direction - still holds up, and you don't notice missing shadows so much in the middle of a frenetic sequence anyway.

Good to see ray tracing coming along. You could get the same shadows and lighting in a modern rasterising engine now as demonstrated in the RTX version, but at the cost of much more development time. Graphics like that being available to smaller studios and larger games being feasible for bigger studios would be great. HL2 is massive compared to modern shooters, and not having to spend forever tweaking each scene helps with that.

When I was still dual-booting Windows and Linux, I found that "raw disk" mode virtual machines worked wonders. I used VirtualBox, so you'd want a guide somewhat like this: https://superuser.com/questions/495025/use-physical-harddisk-in-virtual-box - other VM solutions are available, which don't require you to accept an agreement with Oracle.

Essentially, rather than setting aside a file on disk as your VM's disk, you can set aside a whole existing disk. That can be a disk that already has Windows installed on it, it doesn't erase what you have. Then you can start Windows in a VM and let it do its updates - since it can't see the bootloader from within the VM, it can't fuck it up. You can run any software that doesn't have particularly high graphics requirement, too.

I was also able to just "restart in Windows" if I wanted full performance for a game or something like that, but since Linux has gotten very good indeed at running games, that became less and less necessary until one day I just erased my Windows partition to recover the space.

Disappointing that there's no "bridges" count on there, am invested in it now. Hopefully something big to come, once they've stopped the ruzzians from being able to supply reinforcements.

It's a simple alphabet for computing because most of the early developers of computing developed using it and therefore it's supported everywhere. If the Vikings had developed early computers then we could use the 24 futhark runes, wouldn't have upper and lower case to worry about, and you wouldn't need to render curves in fonts because it's all straight lines.

But yeah, agreed. Very widely spoken. But don't translate programming languages automatically; VBA does that for keywords and it's an utter nightmare.

If you move past the 'brute force' method of solving into the 'constraints' level, it's fairly easy to check whether there are multiple possible valid solutions. Using a programming language with a good sets implementation (Python!) makes this easy - for each cell, generate a set of all the values that could possibly go there. If there's only one, fill it in and remove that value from all the sets in the same row/column/block. If there's no cells left that only take a unique value, choose the cell with the fewest possibilities and evaluate all of them, recursively. Even a fairly dumb implementation will do the whole problem space in milliseconds. This is a very easy problem to parallelize, too, but it's hardly worth it for 9x9 sodokus - maybe if you're generating 16x16 or 25x25 'alphabet' puzzles, but you'll quickly generate problems beyond the ability of humans to solve.

The method in the article for generating 'difficult' puzzles seems mighty inefficient to me - generate a valid solution, and then randomly remove numbers until the puzzle is no longer 'unique'. That's a very calculation-heavy way of doing it, need to evaluate the whole puzzle at every step. It must be the case that a 'unique' sodoku has at least 8 unique numbers in the starting puzzle, because otherwise there will be at least two solutions, with the missing numbers swapped over. Preferring to remove numbers equal to values that you've already removed ought to get you to a hard puzzle faster?

In which case, the job becomes transferring the bottled samples into sample tubes in trays so that the machine can process them, and usually adding a barcode to each sample tube. The sample tubes need to be kept immaculate as well - some of the things that we test water for, like pesticides, are only present in miniscule concentrations. Might not actually save a great deal of time, and you need to buy and maintain a very expensive automated sampler.

When I used to work in the water industry, we were usually able to get PhD-qualified research chemists to do all this mind-numbing laboratory work. There's a bit of a surplus of qualified chemists compared to the number of chemist jobs available, so you got absurdly over-qualified people applying for these roles.

I'd suggest that we do not. How about we split the difference, and drop them off halfway between Belfast and Stranraer, say?

Ah, but if they destroy it inside Russia, then they can wait for the Russians to repair it and then destroy it again. This thing is an essential prop for the Russian economy, they really can't afford to be without it. Might as well turn it into a money sink for them.

Do Iceland still do Official Greggs Products in their freezer section? Steak bakes made at home never tasted quite the same as they do off of the tray of random temperature in the shops, but sometimes that's an itch that needs scratching.

Get a few bottles of suspiciously-cheap no-brand spirits, a few cartons of fruit drink and a couple of bottles of carbonated beverages, empty the whole lot into the 'punch' bucket while the 50-piece snack food selections heats through in the oven, including a few genuine Greggs items as centrepieces? Am telling you, Iceland has everything you need to kickstart a very reasonably-priced house party.

Now, for the best battery health, just need to only charge everything that's used portably but plugged in every night to 80%, and everything that's occasionally moved from place to place but only ever used when it's plugged in to 50%.

100% charges are for those occasions when you'll be working away from power for a few days.
