irelephant [he/him]đWhat's a piece of esoteric knowledge you have?
mlfhifupdown2 has a 15-character interface name limit, and the systemd predictable interface naming system uses the mac address for usb nics (giving them a 15-character name), so if you try to create a vlan subinterface of a usb nic using the standard interface.vlan naming scheme on a systemd host, it will fail, and youâll have to set up systemd network link files to rename the base interfaces to something shorter.
Reminds me of the ESP32 ROM dictionary only taking a 15 character limit and simply bugging out silently without any notification whatsoever. Arduino, so easy to use, great for beginners. It has got all the wild goose chases!
orsettoIâm almost sure the backstory to how you gained this knowledge is âi spent hours debugging something, and that 15 chars limit was the problemâ
Yep exactly! Setting up a raspberry pi low-performance computing cluster with secondary usb nics, going slowly insane trying to figure out why the vlan interfaces wouldnât work when their base interfaces worked just fine, and going down all of the wrong rabbit holes along the way.
And all that just because someone decided that an array bigger that 16 bytes would have been too expensive (/s probably)
Tell me you had to do real work with Systemd and discovered what a steaming useless pile of millennial shite it is as a whole, without using those words. The only cure for lennartâs cancer is to cut it out.
âBizarreâ is the only word from the Basque language that is regularly used in the English language
(Canât wait to be proven wrong in 5⌠4⌠3âŚ)

Sorry for the delay

Ok so the âregularlyâ in my post is doing a bit of lifting. Not too much tho (anchovy is the only other one you could possibly consider frequently used, unless you have a particularly bizarre vocabulary).
bilbo, meaning a sword made in Bilbao,
Bilbo Baggins is the hero of The Hobbit, which every true lemmy user has tattooed on their left thigh.
FriendOfDeSotoTIL Iâm not a true Lemmy user.
DominusOfMegadeusYou shall not pass!
Endymion_MallornThat's what most of their teachers said, I bet.
$50.00 and Iâll keep it quiet.
SnausagesinaBlanketI have it tattooed on my middle thigh.
Thatâs your nose!
I found this really interesting so I looked it up! This website claims that âanchovyâ also came to English from Basque, along with âbilboâ and possibly âjingoâ.
By jingo!
love this concept.
ever found anything interesting?
Crime novelist Jim Thompson [Pop.1,280] wrote a novelization of the TV show Ironside.
If thatâs not esoteric, I donât know what is.
AatubeWow. From everything I could find that he wasnât able to nuke, he sounds like a trip!
CatoblepasHm, I guess this is esoteric in the sense that most people arenât interested in it?
Some clothes are made with whatâs called âslub cottonâ, which is cloth made from cotton thread that has irregular lumps jutting out of it. It gives the final woven fabric an interesting look, almost like static. If itâs done with bright or contrasting colors it can give a really interesting pop to the final item.
ZorsithHuman blood is a valid substitute for eggs in baking.
PerogiBoiCoagulation station
Is it, though? I get that they have a similar protein composition or whatever, but thereâs no way the taste is anywhere near the same. Then again, I guess Iâve never eaten fully raw eggs before (not sure if a semi-runny sunny side up on toast counts, heh).
NichtEliasBut you have eaten raw human bloodâ˝
Youâve never tasted your own blood from like bloody lips and stuff?
Oh, yes, I guess I didnât think of that
I did in a shot. It doesnât taste like egg.
So is semen iirc.
UltraGiGaGiganticThereâs no way. It doesnât taste like eggs at all. Does it? Iâve never tasted raw egg before
For it to be a substitute, it doesnât have to taste the exact same. It just has to have similar properties.
Yeah I remember a video called the âcumletteâ
I learned this from the reverse, as eggs are a valid substitute for human blood in sacrifices.
Human (and animal) blood and eggs can also both be used in place of Styrofoam to gelify fuel for molotovs.
TIL. So many options to make a molotov nastier. Stinky rotten egg fires!
Calm down Dahmer
SneezycatHuh, so thatâs why filloas de sangre are a thing. I always found it weird but it makes sense now. TIL.
whotookkarlThe most efficient base for a number system is e.
We use base 10 with 0-9 digits and each position is a tenâs place, and the efficiency being measured is the product of the number of digits and the length of digits needed to represent a number in a given range of values. So if we used base 2 binary instead of base 10 decimal we only need to remember 2 digits 0-1, but to represent most numbers weâll need more digits, 11 in base 10 is 1011 in base 2. On the other side we could use hexadecimal to write shorter numbers like 11 is B, but need to use more digits, 0-F digits where A-F are the 10-15 digits.
If you try to plot a function that minimizes the efficiency the minimum is at e. So youâd have digits 0-2 and e would be written as 10 since each position is an eâs place.
PhantomPhanaticThis is not a great explanation of radix economy of Base e.
There is (or at least used to be) a debug command to write-protect a hard drive. No idea what itâs for or why such a thing exists, but you flip a certain bit from 0 to 1 and drive no write. I won $100 once at work with this knowledge. We had a training course about how much better the new version of windows at the time was and how much harder it was to break - so hard theyâd pay $100 (in early 2000s money) to anyone who could unrecoverably break their demo windows install during the 10 minute presentation. The instructor (who worked for Microsoft) said heâd been doing this for 6 months and theyâd never had to pay out that prize before, much less 30 seconds in.
Sounds like something registry editor related.
No, this is the debug command thatâs been include in MS-DOS since like version 2.0 (before there even was a Windows, much less Win95/NT/etc. It can let you view and alter the contents of memory at a particular address, etc. We also used it to wipe hard drives by forcibly writing 0s to every block on the drive.
You could do stuff like that with the older DOS versions of Norton Utilities. I used to do fun stuff like set my friendâs files as the drive label. He thought I was basically a wizard.
Yup, or any hex editor that could target memory addresses (some of them were limited to run on a certain file or whatever.) But yeah I used to do similar when I was a kid, I would go into my game files (all DOS games back then of course) and change text strings you could find in there with a hex editor. Iâd just change goofy stuff like âCopyrightâ to âCopyleftâ, âThe bandit strikes the princess!â to âThe dude slaps a hoâ, etc. It was endlessly amusing when I was that age. :)
There are two types of color E-ink displays:
One that uses a color filter on top of a regular black and white particle display, like in their Kaleido screens. This has a faster refresh rate like black and white displays, but the colors are muted and the screenâs âpure whiteâ is much more gray than other displays.
One that uses four colored particles, cyan, magenta, yellow, and reflective white, like in their Gallery screens. This has a much slower refresh rate, but the colors are vivid and the screenâs âpure whiteâ is just as good as a non-color screen.
There are also color transflective LCD screens from other companies that are sometimes marketed as âe-paperâ or âpaper likeâ that are fairly uninteresting.
And there are just straight up backlit LCD screens marketed as âe-paperâ or âpaper likeâ that are just not. XPPen just made one. I personally think this should be considered false advertising.
Not sure if I can call this knowledge since I don't know if it's true, but I think I identified a couple of women from the 8th century CE who are mentioned in some Irish annals as being the same person. As far as I know there's next to no discussion of these women on the internet and there are basically no historical records of them, at least. So I guess if I'm right it's very obscure?
The women in question are Eithne ingen Bresail Bregh and Eithne ingen Cinadhon (and possibly also the legendary Eithne mother of Tuathal Techtmar)
This is a really good one.
T-rex is closer temporally to humans than they were to Stegosaurus.
Wait so t-tex and steggy never hung out? :'(
Nope. They missed each other by about 77 million years or so.
Also phylogenetically and morphologically.
T-Rex is more closely related to sparrows than to stegosaurus.
Indeed. Two very different clades.
Reign of Kings, a medieval online PvE survival game had a bug where the 360 rotation camera could be used in 3rd person mode to look inside of walls of other players. You could even access their chests if they built them against the wall (which they all did).
This meant that you could loot everyoneâs bases without even breaking in. The game went through several major updates with this bug still in place. My brother and I used it extensively.
One day there is a major update and the release notes mention about how they have now finally fixed the âglitch where players items disappear from chests when placed near wallsâ.
Real Gâs move in silence like lasagna.
I remember some roblox games I used to play let you zoom out, look into a secret room and take loot as well.
The SR-71 used an Astroinertial Navigation System that used stars to keep the navigation information accurate as the plane flew over long distances. Normally an inertial navigation system degrades in accuracy over time and distance due to small errors building up and something called gyro drift. The NAS-14V2 used a catalog of known stars and a gimballed telescope to identify specific stars (even during a cloudy day) and determine the position of the stars in relation to the aircraft. Using this information the position of the aircraft can be used to revise the inertial navigation systemâs data every so often so the accuracy is much better.
And this was required because the SR-71 started flying in 1966, and the first GPS satellite didnât launch until 1978. The full GPS constellation wasnât finished until 1990.
