I have always been annoyed by the statement that sqrt(-1) = i.
Note: I'm perfectly fine with the assertion that i^2 = -1.
@Eric Gerlach I... guess, but I'd imagine there are less violent ways to feel that control.
Maybe that's just me.

Fortunately fountain pen ink is water soluble so it often washes right out if you get to it immediately.
Thank God it wasn't my Baystate Blue.

Perusing the terms of service my phone is requiring me to agree to after the update.
Under the section about how they safeguard my data, it reads:
We take data protection seriously. We have put in place physical and technical safeguards to keep the information we collect secure. We also take appropriate measures, in compliance with applicable law, to ensure that the personal information collected by third parties remains secure. However, please note that although we take reasonable steps to protect your information, no website, Internet transmission, computer system, or wireless connection is completely secure.
That's a very verbose way to say "trust us, bro."

Just signed up for DoorDash yesterday to try to diversify our income a little.
Got an email from them this morning. I opened it in neomutt to read that my account had been suspended "due to [my] repeated lateness violations", which is impressive considering I haven't even done a shift yet.
When I tried to show the email to Katy on my phone, the email instead read as a generic welcome letter.
It turns out that the plain text and and HTML parts of the email are completely different.
Things are off to a fantastic start, I see.
Edit: proofreading is for suckers

Every time I read #UnixSurrealism it makes me want to switch to #Plan9.
This is absolutely not a reasonable option for me, but it doesn't stop me from wanting to do it.

in reply to Jonathan Lamothe • •sqrt(1) = -1. We're either constraining the answer to positive numbers or we're not.Pat
in reply to Jonathan Lamothe • • •piecewise function definitions are a thing though, like the abs function for instance
abs(x) = x, for all positive x
abs(x) = -x, for all negative x
sqrt(x) = positive y, for all positive x
sqrt(x) = i * sqrt(-x), for all negative x
I also find arctan really weird, because it only works if you fiddle with the domain (yet it clearly does exist, and is useful)
I enjoy the unpleasant feeling I get when I realise that all maths is made up!

And with quaternions, we can pick any unit, like sqrt(-1) = (i+j+k)/sqrt(3)
y'know, where i = sqrt(-1), j = sqrt(-1), k = sqrt(-1) 😜
