@olligobber @dudeney_puzzles I can get that answer, but I'd also say 12 noon is an answer. And this is why we don't do arithmetic with times.

@11011110 this reminds me of a nice puzzle:
I have a jar containing tea bags, which come in pairs. When I want to make a cup of tea, I reach into the jar and pull a random bag out. If it's part of a pair, I rip it and put the other bag back.
I can't remember how many times I've made tea since filling the jar. What's the probability that I pull out a single tea bag next time?

You really get an appreciation for the noncommutativity of 3d rotations when you've pulled a muscle in your lower back.

I've made a new #3dprinted puzzle: the Hexiamond lantern

@ctdunc it's a classic!

@vam103 I went to a private school

There's esprit d'escalier, and then there's thinking of new ways to deface the "Vote Conservative" sticker your teacher put in her office window twenty years ago

@quarky I have protanopia, which means my eyes don't pick up red light very well. That means I find it hard to distinguish colour combinations like blue/purple or green/yellow.
This app can give me a name for a colour, so I could use it to for example pick a green t-shirt instead of a yellow one.
It doesn't give me a sense of which colours go well together, or which colours look 'nice'.
I used to have an app which simulated what I see in realtime, but it was for an old version of android

@quarky go ahead

@xaphania Color Blind Pal - https://play.google.com/store/apps/details?id=com.colorblindpal.colorblindpal
It can identify colours (but it's got so many names that it's quite jittery) and filter so you can see differences, if not real colours. It doesn't have a simulate mode, which means I can't show others what I see.

Just using my colourblind app to help me appreciate the beauty of autumn leaves 👍 😎 👍

I've just discovered that the character " (a set of double quotes) is a valid HTML attribute name in Firefox.
e.g. <span "="amazing"></span>

@cpsdqs because it's easy to implement in an interpreter?
I can see the train of thought for someone new to programming: I have a variable called $x, and a variable called $y, and I want to use one or the other based on some changing condition. So, I should be able to ask for a variable with a name which is itself a variable

@cpsdqs oh wow! That feels very unsafe

I mean honestly
