  • 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.

    AGPL is a full-on FOSS licence with strong copyleft requirements, not a measly open-source licence like Apache, which could be pivoted to proprietary at a moment’s notice. We’re communicating through an AGPL-licensed system right now as it’s what Lemmy’s licensed as. If they were going for a corporate-friendly licence, AGPL is the last thing they’d choose as it forces you to share source code with even more people than the regular GPL does.

    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.



  • Solar’s a little bit less killy than nuclear (people die when mining raw materials and from falling off rooftops when installing panels) and wind turbines are a little more dangerous than nuclear (mining raw materials, falls during installation/maintenance and people burning to death during maintenance), but hydroelectric power is much more dangerous than nuclear (mainly from drownings after dams burst). Until very recently, nuclear was the safest means of power generation by a wide margin, so if safety is the main concern, there should be a lot more of it.

    A big reason for this is that a single nuclear power plant can power a city despite having the same footprint as a small village worth of wind turbines or solar panels and running for decades off a wheelbarrow of fuel, so there’s much less for construction workers and miners to do and fewer opportunities for them to die. It only kills when there’s an accident bad enough to make international news and remain in the public consciousness for decades, and accidents that bad have only happened a handful of times.


  • 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.


  • If you’re dying of thirst, you wouldn’t appreciate a life preserver and if you were drowning, you wouldn’t appreciate a glass of water. Lots of men are so compliment-starved that they’d appreciate being catcalled even with all the negative implications, and I imagine that plenty of men who catcall have never considered that them appreciating the same in reverse wouldn’t mean there’s no good reason for women not to want to be catcalled.



  • 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.
