Tell me a factoid I might not know about. It could be some weird edge case, a moment in history, or little known reasons for why some software behaves the way it does.

If you allow me to blunty borrow a quote:
„Below are the average carbon footprints of different emails:
An average spam email: 0.3 g CO2e (carbon dioxide equivalent)
A standard email: 4 g CO2e
An email with “long and tiresome attachments”: 50 g CO2e“
Not sure if the numbers are correct, but I recently heard about that on the local radio too.

TIL
toLocaleTimeString
in Edge returns a string with directionality characters and so can't be used to set the value of an input element of type time.All MS-DOS .EXE programs start with a magic prefix 'MZ' or 'ZM' (very rare!), because they are the initials of the developer, Mark Zbikowski
en.wikipedia.org/wiki/DOS_MZ_execu...
Win/386 (and Win95 and OS/2) .VXD files use the Linear Executable (LE) format, which contains 3 different executable text sections: one for 32-bit protected mode, one for 16-bit protected mode and one for 16-bit real virtual mode, you get to manage the shared state yourself... Don't write one!
SMARTDRV.EXE (nobody remembers this right?) is/was a polyglot executable that could be loaded as an MS-DOS device (usually .SYS), or a Win/386 driver (usually .VXD) OR executed on the command line to manage itself. It thus contains 5 different executable text sections.
For the ultimate in insane polyglot'ness, check out POC||GTFO publications (sultanik.com/pocorgtfo/) where Ange Albertini (github.com/angea) officially does voodoo.
Punch cards, the foundation of all computer programming, were inspired by automated looms. See en.wikipedia.org/wiki/Jacquard_loom.
Americans pronounce "cache" as "kaysh", but Australians are more likely to pronounce it like "cash".
Oh, and UK/Eire-denizens pronounce "router" like "rooter" - but that's got certain connotations here in AU/NZ ;)
Have you ever asked Siri about "Beatbox"?
useless? here ya go! Peter DeChamp Richardson has been coding for 25 years (that guy is me :P)
back in the day, you have a few models of ibm printers distinguished mostly by duty cycle. you customize via print chains that the operators can change based on what kind of material is being printed. it is possible that an APL chain was manufactured (I've never seen one in the wild, while working with ibm mainframes from 60's to 90's). what IS common is the APL typeball for the Selectric family of typewriters and teletypewriters. I even had one for a few years even though I was only an occasional user of APL, then it got lost in an office move.
so it is more akin to GM creating a special tire rim than a special truck model.
Wat is a talk on all the weird things in programming, the things that make you say
"Wat"

I highly reccomend this :)
The hashtag/pound sign,
#
, is originally known as the octothorpe.WellActually that's the proper name for it, from a typesetting point of view.
Actually, in my youth, we called it "trace" (and I still use it sometimes) because the TRACE command in Apple II BASIC, outputs the line numbers prefixed with #.
I learned much later that in some places # is used instead of № character.
In 2009-2010 Google tried to merge a separate version of Python inside the official one but didn't ultimately succeed.
The story around it was interesting for a few reasons:
The reason it failed:
So, it was a good idea, but it technically didn't work the way they tried it and there was not enough support around it to keep at it for a long time and hopefully improve the performance gains.
I think this story mostly speaks of what it means to mantain a hugely successful open source project and the relationship with contributors, even if they are a big company ;-)
If anyone is interested, the details and the story are here: python.org/dev/peps/pep-3146/
Tesla invented the radio.
Tesla (the band, a great band, BTW, still touring and still great live) released an album called "The Great Radio Controversy".
They did! I owned that album when it came out. Great songs. Great album. Great band!
A stolen Tesla would be called a "Edison"?
Ha! That's probably about right :)
In some programming languages, 0.1 + 0.2 doesn't always equal to 0.3. It would give you 0.30000000000000004 or something along the lines. In fact, you can try it out in your browser for Javascript at least.
For more info: 0.30000000000000004.com/ and also there's a list of the programming languages where this phenomenon occurs.
Alan Turning helps to lay the foundation of the software industry & AI during world war 2 as a codebreaker of the enigma machine.
