Network protocols for dummies
  • Not really a problem with UDP itself, but with some very old protocols like DNS that rely on UDP but can’t be changed because of compatibility. If you’re writing a new service that uses UDP, there’s nothing stopping you from designing it so that it doesn’t provide an opportunity for bandwidth amplification.

  • Linus does not fuck around
  • I find it ironic that Linus’s explanation for ENOENT being invalid for an ioctl given its meaning of “No such file or directory”, while simultaneously ioctl can return ENOTTY when using a mismatched device fd despite the error meaning “Not a typewriter.”

  • inb4 Call me what you want but pay me the same
  • The fact that most universities will graduate CS majors without ever teaching them how to use a debugger, build system, or version control system shows how useful they are to actual engineering work.

  • big deal
  • Right? Most of the time when I build linux I’m not using GNU because of its burdensome license. Realistically you usually don’t need most of the binaries anyway, and those you do like echo and ls are trivial to reimplement, at least for their common functionality.

  • When you need to retire an old server
  • Honestly by the time I decide to retire an old machine, it’s because I’ve developed so much animosity towards it that I’m much more likely to have an attitude of “good riddance” than “farewell old friend”.

  • The US is normalizing the cruelest mass killing method to stop bird flu
  • future generations will look back on eating meat as a barbaric mistake

    Primates, including humans, evolved to be omnivorous. In the 200,000 year history of the homo sapiens species, only the most recent 3% have had the benefit of agriculture. Even then, only 0.1% have had the benefit of the industrial revolution which could in theory provide enough calories and nutrients for all humans with a purely herbivorous diet.

  • Google Maps widely rolling out new color palette
  • I don't understand how this is getting approved.

    Because you get promoted for changing things, not for keeping things the same. Almost every change like this is motivated by someone trying to get promoted.

  • This Louisiana Town Runs Largely on Traffic Fines. If You Fight Your Ticket, the Mayor Is Your Judge.
  • lawbreaking while driving is widespread on American streets to a level so extreme…

    Is this not the case everywhere? If anything, speeding, distracted driving, and running stop signs / ignoring traffic signals is much more common in other parts of the world.

  • Sweden’s Tesla blockade is spreading — Starting Friday, dockworkers in all Swedish ports will refuse to offload Teslas, cleaning crews will no longer clean showrooms, and mechanics won’t fix chargi...
  • “Right to work” refers to the fact that in those states, unions cannot force membership or payment, or force you to participate in labor strikes. You can still have a union in those states, but it’s very difficult for them to be effective because most people will choose not to pay into it, and strikes have significantly less bargaining power if there’s no legal obligation for union members to follow through with a strike.

    The result is that in such states, there are very few unions, and so very few protections against firing workers for arbitrary reasons.

  • Its most common use case is interrupting games
  • There’s also no reason for a game to inadvertently trigger it. All games should clear the SKF_HOTKEYACTIVE flag on launch to disable the feature trigger during gameplay. Unreal, Unity, and most other engines do this by default.

  • Choose wisely!
  • transfer of matter or energy from one point to another without traversing the physical space between them

    Right. So stand one inch in front of a piece of glass. Your nose teleports 7” forward and is now 6” behind the glass. All good. Your tongue teleports 7” forward and is now 5” behind the glass. Still good. Your cheeks teleport 7” forward and are now 4” behind the glass… Your ears teleport 7” forward and are now 3” behind the glass… Your spine teleports 7” forward and is now just barely behind the glass… Your shoulder blades teleport 7” forward and are now still in front of the glass. Your ass cheeks teleport 7” forward and are still well in front of the glass. You now have a plane of glass running through the entire length of your body, bisecting your ass, spine, shoulder blades, and the back of your head. The effect of this bisection is left as an exercise for the reader’s imagination.

  • Gitlab now requires phone number/credit card verification
  • deleting someone's entire git history

    Based on the image text this is for new accounts only. My account has neither phone nor credit card and I’ve not been asked to re-verify. Maybe they’re having problems with bots at the moment.

  • Choose wisely!
  • I wouldn’t interpret 7 inches as the amount of a gap you can cross - I would interpret it as literally translating your body 7 inches in one direction. Unless you can fit your body between two planes 7 inches apart, you’re not going to be teleporting through any barriers.

    TIL the correct spelling of "nowadays"

    Apparently “nowdays” isn’t a word.

    After working with linux drivers for far too long, I’ve developed some strong opinions on the so-called “APIs” they implement.

    What created this web structure?

    Seattle area, about 30 feet up in a tree. A few small dark flying insects were buzzing around it but I couldn’t see them clearly.

    Will dessicant actively dry wet filament?

    I know that heating wet filament in the oven is the best way to dry it, and that desiccant is typically used to keep filament dry, but will it also eventually dry a spool that has been sitting out in a humid environment? If so, how long would this typically take?

    For example, I have a 1kg spool of tightly-wound PLA sitting out at 55% RH for months. If I put it in an airtight container with sufficient desiccant, will it eventually become dried? And how long would it take?
