  • I’ve got a textured PEI bed and when I’ve printed TPU, the adhesion has been perfect, i.e. good enough that the part wasn’t going to go anywhere unless I wanted it to, but still easy enough to remove when the print was done and the bed had cooled. I guess it could vary from filament brand to brand, so it’s possibly worth trying the same brand as I used, which was cheap Geeetech stuff. It’s £8 a roll, and I’ve used their cheap PLA for ages. I wouldn’t recommend their ABS+, though, as it seems to break down at the lowest temperature that gives reasonable layer adhesion.

    Variations of this meme get posted every week, but I’ve never experienced it, despite having had tens of grub updates murder-suicide the Windows boot loader and grub itself across five or six different machines. Thankfully, it’s pretty easy to rebuild a Windows boot partition, but the frequency that I’m hit with this problem is one of the major reasons I avoid using Linux. Eventually I’m going to have to switch, but that’s driven mainly by Windows getting worse rather than any of the pain points I’ve had when trying to switch full time in the past having been fixed.


  • It depends on the kind of acceptance. If you accept that certain things will be harder for some people and make reasonable accommodations so they can get on with their lives, then people can get on with their lives. If you accept things will be harder so use that as an excuse for people never doing anything without removing any of the obstacles stopping them doing things, they’ll never get anything done. It’s really just addressing the problems versus deciding the problems are inevitable and giving up. That said, giving up can be a lot less miserable than refusing to acknowledge problems and yelling at people when they don’t keep up.



  • Thermal problems are much less likely to kill hardware than they used to be. CPU manufacturers have got much better at avoiding microfractures caused by thermal stress (e.g. by making sure that everything in the CPU expands at the same rate when heated) and failures from electromigration (where the atoms in the CPU move because of applied voltage and stop being parts of transistors and traces, which happens faster at higher temperatures). Ten or twenty years ago, it was really bad for chips to swing between low and high temperatures a lot due to thermal stress, and bad for them to stay at above 90°C for a long time due to electromigration, but now heat makes so little difference that modern CPUs dynamically adjust their frequency to stay between 99.0° and 99.9° under load by default. The main benefit of extra cooling these days is that you can stay at a higher frequency for longer without exceeding the temperature limit, so get better average performance, but unless your cooling solution is seriously overspecced, the CPU will be above 99.0° under load a lot of the time either way and the motherboard just won’t ramp the fan up to maximum.


  • The last time they had plenty of stock and cards people wanted to buy at the same time was the RX 200 series. They sold lots of cards, but part of the reason people wanted them was because they were priced fairly low because the cards were sold with low margins, so they didn’t make a huge amount of money, helping to subsidise their CPU division when it was making a loss, but not more.

    Shortly after this generation launched Litecoin ASIC mining hardware became available, so suddenly the used market was flooded with these current-generation cards, making it make little sense to buy a new one for RRP, so towards the end of the generation, the cards were sold new at a loss just to make space. That meant they needed to release the next generation cards to convince people to buy them, but as they were just a refresh generation (basically the same GPUs but clocked higher and with lower model numbers with only the top-end Fury card being new silicon) it was hard to sell 300-series cards when they cost more than equivalent 200-series ones.

    That meant they had less money to develop Polaris and Vegas than they wanted, so they ended up delayed. Polaris sold okay, but was only available as low-margin low-end cards, so didn’t make a huge amount of money. Vega ended up delayed by so long that Nvidia got an entire extra generation out, so AMD’s GTX 980 competitor ended up being an ineffective GTX 1070 competitor, and had to be sold for much less than planned, so again, didn’t make much money.

    That problem compounded for years until Nvidia ran into their own problems recently.

    It’s not unreasonable to claim that AMD graphics cards being in stock at the wrong time caused them a decade of problems.






  • The feedback in the article was obviously far from perfect, but from the sound of it, “good attempt” could be an actively harmful thing to say. Lots of effort had gone into making the wrong thing and making it fragile, which isn’t good at all, it’s bad. If you’d asked an employee to make a waterproof diving watch, and they came back with a mechanical clock made from sugar, even though it’s impressive that they managed to make a clock from sugar, it’s completely inappropriate as it’d stop working the instant it got wet. You wouldn’t want to encourage that kind of thing happening again by calling it good, and it’s incompatible enough with the brief that acknowledging it as an attempt to fit the brief is giving too much credit - someone who can do that kind of sugar work must know it’s sensitive to moisture.

    The manager can apologise for not checking in sooner before so much time had been spent on something unsuitable and for failing to communicate the priorities properly, and acknowledge the effort and potential merit in another situation without implying it was good to sink time into something unfit for purpose without double checking something complicated was genuinely necessary.





  • There are already slats so the only hole you can get a fork into is the earth, unless you’ve already got something convincingly shaped like an earth pin in the earth hole to open the slats over the live and neutral. If you’re going to that much effort to zap yourself, the switch isn’t going to be much of a hurdle.

    I’d suspect that it’s largely because it’s more convenient to have a switch than to unplug things and plug them back in again, especially as our plugs are a nightmare to step on to the point that Americans complaining about stepping on lego seems comical to anyone who’s stepped on lego and a plug.




  • Putting "false" in a YAML file gives you a string, and just false on its own gives you a boolean, unless you tell the YAML library that it’s a string. Part of the point of YAML is that you don’t have to specify lots of stuff that’s redundant except when it would otherwise be ambiguous, and people misinterpret that as never having to specify anything ever.
