Egregious. I feel your pain.

There’s notation for that - (x0 - δ, x0 + δ), so you could say
f(x0 - δ, x0 + δ) ⊂ (L - ε, L + ε)

I don’t think you can use the x0 plus minus delta in the bracket (or anywhere), because then the function that’s 1 on the rationals and 0 on the irrationals is continuous, because no matter what positive number epsilon is, you can pick delta=7 and x0 plus minus delta is exactly as rational as x0 is so the distance to L is zero, so under epsilon.

You have to say that
whenever |x - 0x|<delta,
|f(x) - L|<epsilon.

But I think this is one of my favourite memes.

Yeah, but you don’t have more than two options for president of the united states. You have the one supporting unions and the weird racist loony hater one. Anyone suggesting something else might happen this year is lying to you.

I had an old little red Toyota Yaris that I called Jennifer, because it looked like a Jennifer to me.

Now I have a dark blue Ford Focus that I call James for pretty much the same reason.

I… don’t seem to name cars like you other folks do.

I take that as a compelling recommendation for Signal.

What a fantastic book. Thanks.

“Orientated” is reasonably common in British English, I think. I remember thinking someone had misspelt it the first time I saw “oriented” written down.

I can’t help feeling that Elon had one of his “you’re all useless and fired” moments with a designer who pointed out some fact or other about aerodynamics and broad appeal, and Elon just said. “It’s easy. Give me a pen… Look. There you go. Truck. CYBER truck. It’s so cool. I told you it was easy.”
They said “OK we’ll use this style and flesh it out into a design the engineers can work to.”
“No, just give them this. This is how it should look.”
“But…”
“No, who’s in charge here? Do you want to be fired too? It has to look like this. Make it like this. Otherwise you’re fired.”
“OK I’ll give it to the aerodynamicists to get it to work as close as possible to this.”
“WTF?! Don’t give it to those idiots, JUST MAKE IT LIKE THIS. If it DOESN’T look JUST LIKE THIS, you’re FIRED.”
“OK Elon.”
“It had better FUCKING LOOK LIKE THIS.”
“Got it, Elon. Exactly like this.”

Is that Bill Bailey?! https://www.arenaentertainments.co.uk/wp-content/uploads/2013/09/bill-bailey-425x312.jpg

I vote for not giving corporations shit for one of the few positive things they do. Honestly, I worry that this backlash against corporations supporting LGBTQ+ people is actually often being pushed by homophobes.

Maybe it’s shallow and maybe it’s not very long lasting, but at least it’s public and positive.

I very much like that I have a clear cut answer for this now.
