The other night I dreamt there was an R-rated remake of Captain Planet for the 2020s, with gore and swearing and everything, targeting the millennials like myself who grew up with that show.
NGL, I'd probably watch the shit out of that, provided it kept the hand-drawn, celluloid animation style.

Yeah, it's not going well…

TIL that "ACAB" in hexadecimal is a prime number (44,203).
So not only are all cops bastards, they're only divisible by themselves (or something).

I misread one of Bluesky's trending topics, "NFL coaching changes" as "NFT coaching changes".
I'm not sure what that would look like, but I laughed my arse off anyway.

There's a key on the table in our backyard. Nobody knows where it came from, what it opens, or when it appeared. All we know is it was likely "gifted" to us by the neighbourhood magpies as thanks for the frequent feeds they cheekily solicit, as they've been known to do with other random objects.

YAML is my favourite esolang.
In all seriousness though, this format needs to die.

The yaml document from hell
As a data format, yaml is extremely complicated and it has many footguns. In this post I explain some of those pitfalls by means of an example, and I suggest a few simpler and safer yaml alternatives.

Mark Zuckerberg is frequently likened to a lizard, but as anybody who's ever owned a bearded dragon can attest, lizards have personality.

So a temperature of 41 °C is forecast for tomorrow. Fire warnings abound in Victoria. Nice and toasty.
For the Yanks, that temperature is roughly 106 °F(ucked).

Got an e-mail from Google titled "You’re now using Gemini on web" (because I think I visited their "gemini." subdomain by accident or something). When I went to disable it and delete whatever it considered my "prior usage", I was presented with this absolute gold nugget of user interface design. 🏆

Websites that allow users to toggle between colour motifs with a setting like…
1. Light mode
2. Dark mode
3. Use system's current mode
… have absolutely no business making Light Mode the default, instead of the obvious choice of honouring the system's current motif (choice 3).
It's baffling. 😒

Excel formulas are a Turing-complete programming language, yet it has no (canonical) name. Is it named "Excel"? If so, does the name hold when the language is implemented by OpenOffice? Or Apple's "Numbers" app?
This would shit me more if I actually worked with spreadsheet software.

![A meme headlined with the caption:
"Reviewer: Please don‘t ‘leave the proof as an exercise to the reader’.
Salty technical writer: Fine.”
Below the caption is a photo of a maths textbook[1] opened to page 165, with the page's contents reading:
[begin quote]
“And if you’re not an idiot, it would follow that:
𝑓⁎|𝑋,𝑋⁎,𝑦,𝜃,σ²⁄𝜀∼𝑁(𝐸(𝑓⁎),𝑉(𝑓⁎))
In case you fell asleep during the lecture, let’s remember that:
𝐸(𝑓⁎) = 𝑚ₓ⁎ + 𝐾ₓ⁎,ₓ[𝐾ₓ,ₓ + σ²⁄𝜀𝐼]⁻¹𝐾ₓ,ₓ⁎
For those who sniffed too much Elmer’s glue in the second grade, don’t forget that:
𝑙𝑜𝑔(𝑝(𝑦|𝜃,𝑋)) ∝ −¹⁄₂[𝑦ᵀ[𝐾ₓ,ₓ + σ²⁄𝜀𝐼]𝑦 + 𝑙𝑜𝑔(𝐾ₓ,ₓ + σ²⁄𝜀𝐼)]
Those who passed kindergarten may remember that thus it would follow:
[𝐾ₓ,ₓ + σ²⁄𝜀𝐼]𝑦 = 𝐿ᵀ∖(𝐿∖𝑦)
For those who might have been dropped on the head as a child, let’s remember that:
<Equation that refers something called "exp">
In which exp is exactly what you think it is, and finally:
<See above>
[end quote]
The textbook in question is "How to prove anything: 30 absurd research papers no one else was brave enough to publish" (ISBN: 9781806118922, 1806118920) (OCLC Number: 1545080733), and the meme was originally sourced from Reddit: https://www.reddit.com/r/mathmemes/comments/1phefxd/just_leave_it_as_an_exercise/](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:xpnah7xsi3nbbq4wqww7jued/bafkreifeake65vj7uhyejb5mhrtluhtd7xwngodhcxxl2dprg7j4p7xdaq@jpeg)
