Here are some values that are (understandably) not listed on the blog. They happen only due to the limited precision of floating point formats.

  128              = √(2 / √√(√2 - (2 / √2)))
  8192             = √√(2 / ((√2 * √2) - 2))
  16384            = (2 / √√(√2 - (2 / √2)))
  67108864         = √(2 / ((√2 * √2) - 2))
  134217728        = (2 / √(√2 - (2 / √2)))
  4503599627370496 = (2 / ((√2 * √2) - 2))
  9007199254740992 = (2 / (√2 - (2 / √2)))
  6369051672525773 = (√2 / (√2 - (2 / √2)))
I found these by accident a long time ago but kept them because they do "work". Try to input one expression in the lil box in https://www.wolframalpha.com/?source=nav and they will quickly evaluate to these values; the charade goes away after you press Enter and get the (mathematically) correct answer.

My old solvers from what feels like a previous life: https://madflame991.blogspot.com/2013/02/four-fours.html https://madflame991.blogspot.com/2013/02/return-of-four-four...

That was fun

I can't recommend "return true to win" (https://alf.nu/ReturnTrue) enough to learn how to golf JS. I think it's more accessible to learn one 10-20 char snippet at a time than a big project like a 1k submission.

In certain conditions gcc will actually generate instructions that use this same bitvector described: https://godbolt.org/z/6Gfjv6PGd (notice the funny 130159 value in there)

The only thing I did was to adjust the range of characters so that the bitvector fits 64 bits. Sadly, I do not this it would work for the author's bigger range.

Not really; see https://news.mit.edu/2022/divorce-albatross-shy-males-0913 and https://oceanconservancy.org/blog/2020/02/13/albatross-reall...

I tried the demo and I liked it!

I would prefer if I could pick a color in a faster way than switching to the color picker or using the palette: maybe middle click or Ctrl + left-click (gimp does that). It would reduce the mouse travel quite a bit; sometimes I happen to have the exact color I want next to my cursor.

I would also suggest putting the trailer on Steam. All I see is images in the steam carousel thing; I think the trailer being in the carousel would help.

I've been playing the same 2 games for many years and I think I got pretty good at them and I've used multiple accounts - under your assumption I look like a cheater.

> but isn't the "general" architecture of most of our computers "von neumann"!?

That's something I was also curious about and it turns out Arduinos use the Harvard architecture. You might say Arduinos are not really "computers" but after a bit of googling I found an Apple II emulator running on an Arduino and, well, an Apple II is generally accepted to be a computer :)

What would prevent me from walking around the street or in semi-public places recording non-stop on my phone? Heck, I could have a few phones in my pockets!

I was thinking the same; they have a map of their route and I see they went through Rahova, Ferentari and they somehow missed Zetari and the cemeteries there on their way to Anghel Nutu; those areas are actually the worst off of the entire city - quite a coincidence :/

I’ve been almost daily through these areas for years; used to actually live on str Anghel Nutu; finding this on HN on christmas day is a bit surreal. I come here for tech articles mainly
