This blog is just wow. Beautiful interactive illustrations of physics and mechanics.
PSA: recognizing drowning
> The Instinctive Drowning Response—so named by Francesco A. Pia, Ph.D., is what people do to avoid actual or perceived suffocation in the water. And it does not look like most people expect. There is very little splashing, no waving, and no yelling or calls for help of any kind.
Refresher for anyone who might spend time near water this year.
Here's a one-liner to rsync a folder onto a FAT disk that doesn't support special characters, if you don't mind the files being renamed around those special characters.
$ mkdir /tmp/music-posixovl && /sbin/mount.posixovl -S $REAL_MOUNTPOINT /tmp/music-posixovl && rsync -rltuhv --size-only --delete-before --inplace $SOURCE_DIR /tmp/music-posixovl/$DEST_SUBDIR && umount /tmp/music-posixovl && rmdir /tmp/music-posixovl
Happy Pride Month to all the long-dead historical queer couples, doomed to be forever described by museum plaques as “close friends,” “like siblings,” and my personal favorite, “the nature of their relationship is unclear” 🏺 🌈
#Cryptography question: I'm building a project that deduplicates stored data chunks. Chunks are encrypted using their own hash as the key. For this to not break deduplication, I think the IV needs to be deterministic?
What security properties am I losing by doing this, and is there a better way (that does not involve "just use ZFS" or similar)?
@TQ doesn't it just make your heart smile that "phpbb but make it fedi" exists in this world
Holy moly, a historian got ahold of the original tape of this famous Martin Luther King Jr interview in Playboy in 1965 where he harshly criticized Malcolm X, really the single source for the idea he vehemently disapproved of Malcolm X, and it turns out the criticism of Malcolm X was completely fabricated afterwards by the interviewer Alex Haley. Haley later wrote Roots, which unfortunately it turned out he'd plagiarized significant parts of.
Raspberry Pi Foundation seems to be collecting serial numbers/MAC addresses during the first boot of Raspberry Pi OS?
Take a look at the following function inside `piwiz`, their first boot wizard:
https://github.com/raspberrypi-ui/piwiz/blob/master/src/piwiz.c#L2381-L2393
That app either reads the OTP registers 64-65 which contain the MAC address, or the serial number reported by CPU. Then, they use Chromium first_run_tabs preference key to send a SHA256-hashed MAC/SN to their server (hxxps://welcome.raspberrypi.org/raspberry-pi-os?id=SHA256SN)
What's going on with #NixOS right now is a good example of why having sponsors doesn't mean you have an infinite budget.
Once the sponsor pulls out - and they eventually will! - it's always the community that's left to pick up the pieces, and so you have an obligation to ensure that the funding burden is minimal.

Sometimes horny on main (behind CW), very much into kink (bondage, freeuse, CNC, and other stuff), and believe it or not, very much a submissive bottom :p
My spoons are limited, so I may not always have the energy to respond to messages.
Strong views about abolishing oppression, hierarchy, agency, and self-governance - but I also trust people by default and give them room to grow, unless they give me reason not to. That all also applies to technology and how it's built.
