  • Someone was telling me the other day that the cheapest new car available in the UK was an electric Dacia. Obviously, you can get a used car for less than a new one, but electric cars are within reach of normal people, or at least normal enough people to not have Mr Moneybags budgets.


  • People fall off rooftops fitting solar panels, burn to death repairing wind turbines that they can’t climb down fast enough to escape, and dams burst and wash away towns. Renewable energy is much less killy than fossil fuels, but per megawatt hour, it’s comparable to nuclear, despite a few large incidents killing quite a lot of people each. At the moment, over their history, hydro is four times deadlier than nuclear, wind’s a little worse than nuclear, and solar’s a little better. Fission power is actually really safe.

    The article’s talking about fusion power, though. Fission reactions are dangerous because if you’ve got enough fuel to get a reaction at all, you’ve got enough fuel to get a bigger reaction than you want, so you have to control it carefully to avoid making it too hot, which would cause the steam in the reactor to burst out and carry chunks of partially-used fuel with it, which are very deadly. That problem doesn’t exist with fusion. It’s so hard to make the reaction happen in the first place that any problem just makes the reaction stop immediately. If you somehow blew a hole in the side of the reactor, you’d just get some very hot hydrogen and very hot helium, which would be harmless in a few minutes once they’d cooled down. It’s impossible for fusion power, once it’s working, not to be the safest way to generate energy in history because it inherently avoids the big problems with what is already one of the safest ways.



  • That’s misleading in the other direction, though, as PhysX is really two things, a regular boring CPU-side physics library (just like Havok, Jolt and Bullet), and the GPU-accelerated physics library which only does a few things, but does them faster. Most things that use PhysX just use the CPU-side part and won’t notice or care if the GPU changes. A few things use the GPU-accelerated part, but the overwhelming majority of those use it for optional extra features that only work on Nvidia cards, and instead of running the same effects on the CPU if there’s no Nvidia card available, they just skip them, so it’s not the end of the world to leave them disabled on the 5000-series.


  • If you write cross-platform software, the easiest solution is usually to pretend everything’s Unix. You’ll hit some problems (e.g. assuming all filesystem APIs always use UTF-8 will bite you on Windows, which switched to UCS2 before UTF-8 or UTF-16 were invented, so now uses UTF-16 for Unicode-aware functions as that’s the one that’s ABI compatible with UCS2, and passing UTF-8 to the eight-bit-char functions requires you to opt into that mode explicitly), but mostly everything will just work. There’s no XDG_CONFIG telling you to put these files anywhere in particular, as Windows is Windows, so most things use ~ as a fallback, which Windows knows to treat as %USERPROFILE%.




  • Male to female A-to-A cables are pretty common (they’re just basic extensions) and totally legal under the spec provided they’re limited to a certain length or contain a powered repeater. It’s just the rare male-to-male (which my keyboard stupidly uses) and even rarer female-to-female that aren’t legal. There’s also the exception of USB-on-the-go cables with a micro-B end and a female A end for devices like smartphones that are capable of being host or connecting to a host, back before they switched to USB-C.





  • They have to defend their trademark. They don’t have to defend copyright, and most of Nintendo’s reputation comes from copyright claims. Someone streaming a let’s play isn’t selling a counterfeit Mario game, they’re just showing you things in a real Mario game, so there’s no trademark claim.

    They’re also big abusers of the fact that most of the people they make copyright claims against can’t afford to defend themselves against such a behemoth. Even if you’re sure you’ve not violated their copyright and your lawyer’s sure, too, it’ll be much cheaper to roll over than get the legal system to agree with you.




  • To go one better, there’s http://isthereanydeal.com/, which tracks prices across a bunch of vetted key retailers (i.e. companies that buy wholesale keys from publishers and sell them to users, but not grey-market or dodgy sites) so you can see where’s cheapest and get notified of discounts etc.

    Why check GreenManGaming and Steam (and potentially a bunch of their competitors, too) when you could check one site and know who’s best?

    I’ve accidentally made this read like an ad, but they’ve not paid me to say this, I just always check the site before buying games, and have either saved loads of money by doing so over the years, or have ended up buying a bunch of things I’d have ignored on the grounds they were too expensive otherwise. I don’t know in which direction, but it’s definitely changed the amount I’ve spent on games over the last ten years.


  • I’m not arguing for anything in the post above, just pointing out that a broken (or badly repaired) insulin pump is genuinely more dangerous than having no insulin pump. That doesn’t have to count against the right to repair one, as if you’ve got the right to repair an insulin pump, and do so badly, it doesn’t mean you’re legally forced to use it afterwards, just like I’ve got the right to inject all the insulin in my fridge with an insulin pen back to back, but I’m not legally forced to do so.

    I do think the right to repair should be universal, but as I think that medical stuff should be paid for by the state, NHS-style, that would end up meaning that the NHS could repair medical devices themselves if they deemed it more economical to do so and recertify things as safe than to get the manufacturer to repair or replace them. The NHS is buying the devices, and gets the right to repair them, and that saves the taxpayer money, as even if they don’t actually end up repairing anything, it stops manufacturers price gouging for repairs and replacements, and if the manufacturer goes bust or refuses to repair something, there’re still ways to keep things working. It doesn’t mean unqualified end users can’t use their new right to repair their medical devices and risk getting it wrong, but if you’ve got an option of a free repair/replacement, most people would choose the safe and certified repair over their own bodge.


  • If you’ve got a broken insulin pump, assuming you’re in a country with a functioning healthcare system, you should have been given a spare pump with the original, and probably some insulin pens, so when one breaks, you fall back to the spare, and get given a new one to be the new spare (or could get the broken one repaired). Using the spare is completely safe.

    If you don’t have a spare, your sugars would go up over several hours, but you’d have a day or two to get to a hospital and potentially several days after that for someone to find you and get you to a hospital, so it’s not safe, but also not something you’d die from if you had any awareness that there was a problem.

    If you’ve got an incorrectly-repaired pump, you could have it fail to give you enough insulin, and end up with higher sugars, notice the higher sugars, and then switch to the spare. That’d be inconvenient, but not a big deal. However, you could also have it dump its entire cartridge into you at once, and have your sugars plummet faster than you can eat. If you don’t have someone nearby, you could be dead in a couple of hours, or much less if you were, for example, driving. That’s much more dangerous than having no insulin at all.

    Prosthetic legs don’t have a failure mode that kills you, so a bad repair can’t make them worse than not having them at all, but insulin pumps do, so a bad repair could.


  • The article says they were claimed to be found in his car by a then-girlfriend who took $10,000 reward money to testify, not that they were found by law enforcement and collected as evidence and checked against a list of things that were known to have been stolen. It’s plausible that nothing was found and the whole story was made up for cash, or that it was just some stuff he’d bought at a yard sale that was misidentified, or something he’d stolen from somewhere else. Someone saying someone had junk in their car isn’t strong evidence of anything.



  • Either:

    • They’re in denial that this happens (arguably, it didn’t happen, as eventually Tesco lost, and they wouldn’t know about it in the three years Tesco was winning because The Telegraph/Mail etc. wouldn’t report on that).
    • They think worse things would always happen under other systems (e.g. everyone would be a slave of the state and go to gulag if they complained about anything).
    • They don’t see it as an inherent problem with capitalism (e.g. simply make doing this illegal, and refuse to let business lobby to reverse the decision, and everything’s fine).
    • They think this is a good thing (e.g. the fired workers will be incentivised to work harder, then earn a payrise, and use the extra 10p an hour to start a competing multibillion pound supermarket chain).
