How often does branchless programming actually matter?

Jump

  • Necessary for cryptographic code, where data-dependent branches can create a side-channel which leaks the data.

    • I will be returning from a month-long vacation next week. Let’s see if my arch machine will break completely!

  • NixOS + Home Manager user here.

    I run in an opt-in state config. / is tmpfs. /home is tmpfs. /boot and /nix are real filesystems. At boot, the EFI loader reads the configuration from /nix/persist/etc/nixos/flake.nix, symlinks all the programs and configs into / and /home, and startup proceeds as normal.

    That means nothing persists across boots unless I add it to my config. Cruft doesn't accumulate in hidden areas, it's all in my config. That keeps things fast, makes management easier, and makes troubleshooting easier.

    • What does defederating from Meta's Threads.net actually accomplish?

  • They sad threadiverse to distinguish it from the microblogiverse, both are part of the fediverse.

    Twitter, Instagram, & Mastodon = microblogging.

    Reddit, & Lemmy = threaded discussions.

    • So... are Lemmy users also generally crypto supporters?

    Jump

  • Monero's ring signatures are an actually interesting bit of cryptography. And it does provide a real benefit (private transactions) that other payment systems don't. Of course that means it breaks all the anti-money-laundering laws to exchange money to/from Monero, but it's less of a joke than the rest. Still PoW though, so inherently destructive and not something I'll support.

    • The WHO is about to declare aspartame can cause cancer

    Jump

  • "Unsweetened" means no sweeteners added. "No sugar added" means no sugars, but maybe other sweeteners.

    • So... are Lemmy users also generally crypto supporters?

    Jump

  • Hell no.

    They're almost entirely scams. I don't support tricking people out of their money.

    They also ruined crypto as an abbreviation for cryptography, and spam every cryptography-related discussion forum. Even the NIST post-quantum standardization list has been getting their spam.

    • I keep closing my browser tabs by accident with Ctrl + W

    Jump

  • Pretty sure that's been the shortcut since Mozilla Phoenix (now Firefox) introduced tabs in 2002 or so.

    • Now no one will ever see all those super long !remindme bot posts set for 5, 10 or 15 years on Reddit

    Jump

  • Yep, it's just Murphy's Law of data: everything you regret posting will be in public archives forever, everything you want to preserve will have gotten deleted the next time you try to find it.

    • How do you say C#?

    Jump

  • It's officially C♯, not C#.

    • correct answer

    Jump

  • B is your employer's responsibility, and your goal with having a job. A is your responsibility, and their goal with offering a job. If you don't get a living wage, you shouldn't do that job since they're not fulfilling their responsibility.
