  • Here’s one that’s not as consequential as other posts here. It’s not going to change the world, but would make things slightly better.

    Split lock washers are worse than useless. They’re supposed to be a spring against the bolt to help resist it turning back out over time. They don’t. If anything, they make it worse.

    Here’s a NASA publication on fastener design (because of course there’s a NASA publication on fastener design): https://ntrs.nasa.gov/citations/19900009424

    The lockwasher serves as a spring while the bolt is being tightened. However, the washer is normally flat by the time the bolt is fully torqued. At this time it is equivalent to a solid flat washer, and its locking ability is nonexistent. In summary, a Iockwasher of this type is useless for locking.

    This was published in 1990, but we’re still using this shit. Stop. There are many other kinds of fastener locking that work, like nylon locking nuts or threadlock, and we don’t need these.

    Motherboard front panel connectors should be officially standardized. These fucking things have been basically the same since the 90s, but we still have to line up all the individual wires instead of having one plug.

    Oh, and fix RGB headers while we’re at it. They’re the flimseist fucking thing, and you shouldn’t be able to use a 4 pin plug on a three pin header.





  • Every time I see a defense of IPv4 and NAT, I think back to the days of trying to get myself and my roommate to play C&C: Generals together online, with a 2v2 game, with one of us hosting. Getting just the right combination of port forwarding working was more effort than us playing C&C: Red Alert on dial up when we both lived at home.

    With IPv6, the answer is to open incoming traffic on the port(s) to the host machine (or just both since the other guy is might host next time). With IPv4, we have to have a conversation about port forwarding and possibly hairpin routes on top of that. This isn’t a gate for people “who know what they’re doing”, it’s just a bunch of extra bullshit to deal with.



  • Or if you want a shorter version, “circle the part of the chromosome where it says men hold the door open for women”. There are obviously differences between what’s written in genes and the billion little social rules surrounding gender. It makes sense to have different terms to differentiate biology from social rules, and “sex” and “gender” can do that just fine.
