    Yeah, one that I always think of is the see-saw one where a sky diver’s parachute failed so he aimed for a see-saw with a girl sitting on one end which resulted in the girl launched shot upwards and then landing safely on top of a building.

    Their first test used basically a metal plank on a fulcrum and the forces did more to bend the plank than they did to launch the girl and she didn’t get high enough.

    Their second attempt used a see-saw that was built using suspension bridge tech to essentially make it instructable, resulting in fatal forces from the launch. At this point, they called it busted.

    But I see two unrealistic extremes where reality would exist somewhere in the middle where see-saws are designed to not break easily but not to the point of being indestructible and there might be a sweet spot where the forces are high enough to launch girl several stories up but not high enough that she dies from the forces.

    Also, for the bull in a china shop one, I’m guessing that saying resulted from a bull ending up inside a china shop during a running of the bulls event, where stress would be high and there wouldn’t be an easy and obvious path out on the other side, plus maybe a shopkeeper suddenly trying to get it out in a panic. I think that would get the expected result, especially after a few shelves have broken and each step makes more broken sounds.


  • Car doors that aren’t on teslas don’t fail open, they are reliable enough that I can’t think of hearing about any failures that don’t involve a collision and deforming of the door (in which case it’s a fail closed and they use the jaws of life to get people out, or another door).

    An electronic latch is either engaged or it isn’t. Fail open would mean that in the absence of an electronic signal saying it should be closed, the latch will default to not being engaged, which would mean there’s nothing holding the door closed if another force acts on it.

    Don’t assume any benefit of the doubt about Tesla’s. I made no comment one way or another about what I think of their doors vs other doors. For the record, I agree completely that they fucked up this part of the design. The purpose of my comment was to say that taking that design and adding “fail open” to it won’t fix it. Fail open and fail closed both have problems with an electronic latch and the only way to fix it without causing other big problems is to design it in a way that still functions as a door that can be open or latched closed whether or not the electronic part of the latch is working.

    And I’m “deliberately misinterpreting” what fail open means? I’m having trouble understanding how it can mean anything other than how I’m interpreting it, even with your clarification, given the disagreement about other car doors failing open. Maybe it’s a misnomer that I’m misinterpreting but why are you assuming I’m doing this in bad faith?

    The downvotes themselves don’t matter, I asked because I wanted to know the reasoning behind them, well aware that bringing them up at all will probably result in more of them.


  • You cannot say that with statistical certainty. There’s about 8 billion people who haven’t eventually died yet and all it will take is one of them to break that 100%. You should include a disclaimer with an error range or you might get sued by someone who spikes someone’s drink with dihydrogen monoxide and then they don’t eventually die for botching their assassination.

    That said, the statistics are pretty strong. 99.9% is basically 100% plus wiggle room so no one can sue me, so readers should be aware that this dangerous chemical can also go by the name of hydrogen hydroxide and some food manufacturers try to sneak it by with the name aqua in their ingredients list.


  • For the fail-safe bit, if the latching system fails to an unlatched position, then the inertia of the door itself could cause it to open on braking and turns (or if someone leans on it or bumps it), since nothing else would be holding it in place.

    Obligatory fuck Elon Musk lol.

    It’s not generally as bad here as it is on Reddit. I still see the occasional comments that make me wonder if their author has any reading comprehension skills, but Reddit seemed to have representation from those kinds of posters in most comment threads. Even on the topics where Lemmy has general biases for, comments can still go off the beaten trail without getting crucified.

    Though with the smaller sample size of voters, I think Lemmy might see more cases where a comment initially goes one way and then swings the other way, which seems to be the case with my comment above, at least for now (and is part of the reason why I try to refrain from ever commenting on the votes, but usually there’s also a spicy or bolder part of my comment where I’m not as surprised if it goes negative).








  • Yeah golden parachutes are such a joke in this society that likes to pretend to be a meritocracy.

    Though on that note, I’d love to see a law that limits golden parachutes to the lowest paid position in the company. Hell, I’d be ok with that being scaled to full time. Not because disgraced executives deserve even that much but because it would give some incentive to increase pay rates across the company. I’ve also long thought that executive compensation should also be limited by some multiple of the lowest pay. And yeah, I’d include stock options and grants in that (for both employee and executive compensation).


  • IMO a fumbled and later recovered launch is different from the enshitification of video games like P2W, MTX in general, lootboxes, releasing what should be patches as paid DLC, invasive DRM and anti-cheat. I’d file all of those under bad design, while a bad launch is more of a bad execution. There can be overlap, like if they fully intended for early players to fill the role of beta testers.

    The way I approach it is I try to avoid the bad design stuff entirely but just avoid buying new games at release and definitely never pre-order. I’ll also support games in early release if I really like the concept and want to give them a better chance at being able to pull it off, but I go into those with the understanding that it’s not complete right now and there’s a chance it never will be. But I don’t see any reason to hold anything against the games that have messy launches but later recover.

    Though I’ve learned to not jump on the hype train and that makes it much easier to not take any of this stuff personally.



  • I’ve also been avoiding playing games that involve some third party launcher or login. I’m not perfectly consistent with this and have bought some games before realizing they had this, but even steam games can be subject to a company deciding they don’t want to support their game anymore (which IMO is fair) and just killing the game off entirely, which isn’t fair. I’d like to see a requirement that other steps be taken to keep it going without their active support. Like opening the source and relinquishing all copyrights on that code. If they want to keep parts of it, then pull it out into a library that they continue to maintain.



  • I assume it’s like the new car smell. Pleasant or not, it’s from inhaling plastic and paint particles and other chemicals as the excesses evaporate and loose pieces come loose and become airborne.

    Steam Deck is probably similar. Plastics, anti-corrosion coatings on heat sink fins, trace metals and solder, inks from the PCB, maybe the occasional ion leftover if there’s any micro-arcing.

    I’d guess it lasts a long time because the cooling airflow continually erodes whatever is in its path, while new cars don’t have that continuous erosion so eventually all the particles that were going to escape do and the ones left over are more stable.


  • It was bad writing pretty much across the board. Poe, Rey, Finn, and Leia got a pass from me mostly based on not being introduced as a barrier to the other characters and having got shit done previously. I felt as negatively about Luke as I did about Rose or Holdo in that movie, worse even because he could have been and done so much more, despite his past (or maybe because of it, ep 8 Luke was just a disappointment compared to his previous versions, like they took his only negative trait from the earlier films, his whining, and made that his main trait, despite him being mostly over it in ep 6).

    And I agree that Rose wasn’t a Mary Sue, but figuring out the weakness of hyperspeed tracking based on nothing at all was a Mary Sue moment (and Finn looked just as stupid for enthusiastically guessing where her mind was headed).

    And some differences between Poe’s and Holdo’s plans were a) the audience was informed of Poe’s plan (which sounded a lot like a typical Star Wars plan similar to their infiltration of the death star in ep 4) and for all we knew, Holdo had no plan but slowly let her ships get picked off as they ran out of fuel, and b) Poe’s plan made the chase that made up most of the movie more interesting while Holdo’s was a stall and run, which might have been a better plan but was so underwhelming after so much of the movie focused on that stupid chase.

    And yeah, misogyny certainly played a role in the vehemence of the reaction and the bullying of the actors. Incels and other flavours of hate have a higher representation than average in a lot of nerdy niches. I just think that the producers chased that controversy rather than it falling upon them and resent that they did that to those actors even knowing how “fans” had reacted to kid Anakin and Jar Jar.
