We've all got a chicken-duck-woman thing waiting for us @perdvivly - Tumblr Blog

Thinking of doing a bit that’s making a series of tumblr polls about a post I should make like “what should the first letter of the post be” “what should the second letter of the post be” etc. etc. and then finally making that post. But it would be so long and obnoxious that I don’t actually want to do it. But please imagine I did and be appropriately eye-rolly at me

I think the "pre" and "post" parts in "preposterous" should cancel each other out but everyone else seems to find my idea completely erous

I sent a package at the post office today and it was £5.45. The person working at the post office told me as much. I gave her 2 £5 notes and she gave me 2 £2 coins and a 5p coin. I assumed she misspoke and that the price was £5.95 and so I took the receipt and went back to my car. In my car I looked at the receipt and no, it did say £5.45. I briefly considered going back and saying that I think she forgot to give me a 50p coin. But I didn’t have any evidence that I could present to her that she hadn’t given it to me and then I’d concealed it so as to extract an extra 50p from her. Now, of course, she hadn’t actually accused me of this or anything at all because I didn’t go back in and talk to her about it. I felt vaguely uncomfortable at the level of trust I was assuming should be baseline in our interaction. Ultimately I decided I was willing to pay 50p not to have anything that might feel confrontational. I think this is probably a character defect I have and that if I were a better person I would have said something. Maybe I think that I should have given her the chance to display trust instead of assuming she wouldn’t. But would I in her place? It’s uncomfortable because she wasn’t acting on behalf of herself, her concerns are related to her employer. And it was very plausible that I had 50p worth of incentive to lie if I thought I might get 50p out of that lie. Of course, I didn’t, I wouldn’t tell a lie for 50p. But there’s no way she could know that… Okay well, perhaps she could count the money in the till and work out the days takings to figure out I was telling the truth. But what if this wasn’t the first mistake she’d made? Or what if that would consume her time that she could otherwise put to better use. I don’t think I need that 50p. It’s probably not going to be the difference between whether or not I eat tomorrow.

Shannon died for your right to parity

I HAVE BEEN LOOKING FOR THIS FOR MONTHS AND MONTHS. THERE WERE ONLY A FEW DOZEN NOTES WHEN I SAW IT LAST.

Rating: NOT CUTE

Asking a yes/ no question that narrows the pool from 11 options to 1 gained you 3.459 bits of information. Which means if the answer had been no you would have narrowed the pool from 11 options to 10 and gained 0.138 bits of information.

The expected information gain from the question is the probability weighted average of the yes/ no responses, which works out to 0.439 bits.

You could have asked a question with an expected information gain of 0.994 bits by asking something that would split remaining options into 5 vs 6.

Asking questions like this hurts the ghost of Claude Shannon and as such is ghost abuse. Shannon didn’t fight and possibly die for your right to party just so you could ask questions with suboptimal expected information gain.

Went to John Donne Island and turns out it wasn’t an island at all, but a piece of the continent, a part of the main.

Aw that’s cute, this person has some kind of browser plugin that converts their webpages into babytalk… Oops. That’s a Dutch person visiting a Dutch website.
