The requested page title contains unsupported characters: "%E2".

Oddly, when I search for it myself, I get the same URL:

Either Lemmy is messing it up, or the Thunder app is. If I copy and paste the URL, ir works. So maybe Thunder is doing something to the URL when I tap it?

I'm 100% not joking, I once was stuck the the proof of a theorem for a whole week going at it and still wasn't able to prove it... until I dreamed of the solution, woke up at like 3 am, quickly wrote a skecth of my dream's proof and went back to sleep. The following morning I checked that path and boom, there it finally was the solution.

Weirdly enough, this happened twice, although that second time I didn't woke up at 3 am, just in the following morning as usual.

I read somewhere that Mick Jagger (or maybe it was Keith Richard) wrote the riff of Satisfaction in his sleep.

He woke up, grabbed a tape recorder and went "Bum bum. Bumbumbuummm bumbumbum." And sang the one line "I, can't, get noo, sat-tis-fac-tion." And then went back to sleep.

Forgot about it the next morning till they were at band practice and someone found the tape and played it.

Ramanujan's pi formula.

Similar formulas were used to calculate digits of pi very fast etc.

Thunder is encoding the percent-signs, that are used for the original encoding of the dash. Which of course bungles the url.

Presumably it allows Thunder to open URLs with raw Unicode characters in them. But ironically, I've just tried to insert the same address here with the dash preserved, and Thunder converted it to percent-encoding when posting (or Lemmy did, but I doubt that).

Satisfaction was a hit because Jagger has skill, not because he dreamt it.

There are many different formulas for deriving digits of pi, and the history of mathematics has a bunch of people trying to brute force inefficient formulas for pi out to a few digits, as they develop more efficient methods.

Archimedes drew a circle and put some polygons around the inner and outer limits to determine that it was somewhere between 22/7 and 223/71, accurate to within 2 digits. That general polygon method was used by Ptolemy to calculate out to 3 digits, and used by Chinese mathematician Zu Chongzhi to estimate pi at 355/113, accurate to 7 digits.

The polygon method was very tedious, requiring many, many calculations in order to advance just a few digits.

The Liebniz formula was a breakthrough (discovered by Indian mathematician Madhava of Sangamagrama), because discovering that pi/4 was equal to the infinite series 1 - 1/3 + 1/5 - 1/7 . . . meant that someone could calculate some number of digits accurately, and then continue the calculation in a way that reports what is known so far, and can continue down the line towards a more precise result. Still, by itself, it was a very slowly converging algorithm, requiring 5 billion terms just to get to 10 digits of accuracy. Mathematicians got to using other tricks (that, if I'm being honest, I don't understand) to make it faster.

Then Ramanujan discovered series that were rapidly converging (including the one in this meme) where although calculating each term might require a lot of calculations, it would spit out 8 digits for each term you fed it. It became the preferred method for calculating digits of pi, and when computers were developed, they were able to make use of that computational efficiency. It still remains the basis for how a computer will calculate a few million digits of pi.

If you ever do have a dream, write down everything that happened as soon as you wake up. Your ability to "have dreams" and remember them is like a muscle that can be exercised. To exercise it, you have to write them down so they cannot be forgotten.

PieFed did some policy change on... weighting votes for people who vote thousands of times a day, or something like that? PJ said that made him want to change instance again, but he'd done that a few times already and couldn't be bothered with the process again.

What happened to PugJesus?

He'd been unhappy with some stuff the Lemmy devs do for a while, but when kbin shut down, he moved to lemmy, and when piefed seemed like a reasonable alternative moved his accounts and communities to piefed.social.

Then rimu decided that a handful of most active users with hundreds or thousands of upvotes per day shouldn't get to have such an impact, so he installed a daily cap for how many votes per user per day are counted, discarding the rest. Essentially, this limits engagement in an attempt to "even out" its distribution by cutting off the top. It's an opt-out feature for other piefed instances, but on his own (piefed.social), he obviously activated it.

PugJesus, being one of those most active users, was quite upset with the prospect of having to ration his upvotes. By his own description, he'd easily fill out much of that cap just upvoting all the good-faith replies on his posts, let alone if he were to also engage in discussion elsewhere and equally use upvotes there to encourage good-faith conversation. It evidently caused anxiety and soured his experience.

Even if he were to use an account from a different instance, that restriction still affects the communities. Having migrated three times already (idk what the third one was, but given how much effort even one move for a whole community can be...), PJ was tired of it and didn't wanna migrate again. So he did what rimu wanted:

Stop engaging.

(He's around, occasionally, but not nearly as active, nor does he post as much. Can't blame him. Sure isn't helping that there's a certain subset of people that hate him for various reasons. He'd probably respond if I summoned him, but I'm not sure I want to drag him back to that topic and make him feel like he has to comment.)

It was a cap. 240, as far as I know. Given that it would make him ration his engagement and caused him anxiety, he was fed up, but didn't wanna move a third time.

I didn't say it wasn't both. If Keith didn't dream it, Mick's skill couldn't have made it a hit because it wouldn't have existed.
