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...

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

I'm always a bit skeptical about physics because whatever models we find and celebrate now will have to be adjusted at some point in the future. I wonder if there's any way of knowing that something is indeed impossible or if our model of something is final and set in stone.

I'm happy there are at least some universal constants like absolute zero or the max possible temp or planck length.

And as for anything FTL, I hear it breaks the rules of causality and that seems to be a big no-no and is indeed impossible.

I've never heard about the frostbitten onion before and I am Romanian as well - maybe it's particular to some regions?

"It hurts in my dick" is just a more vulgar way of saying "it hurts in my ass" (the ass would be a place you wouldn't care if you hurt or not); more vulgar because "pula" (erect penis) is more vulgar than ass.

The next level of not giving a fuck after that is "it doesn't even hurt in my ass" which I find amusing - to which someone can reply "well, when it's gonna hurt you'll realise how bad it is" in the sense that "you will wake up someday and regret it".

The least vulgar variant is "it hurts in my elbow" - elbows being usually bumped into things and not hurting much (unless you hit that special spot where the nerve lies)

Sexual Economics: A Model of Heterosexual Behavior by Dr. Kathleen Vohs

I'm going to ask a different question: so what if it doesn't handle it? Some of the hardware resources would be spent on dynamic shenanigans instead of the actual game content. In contrast a game running on the same hardware but implemented in C++ would be able to handle/offer more of the content of the game.

But then again 5 years ago hardware was worse; 10 years ago even worse; 20 etc etc. Games had less content but there were still good games, as good as modern ones. Game enjoyability doesn't depend that much on the scale of its content. If a dynamic language pulls the resources down to what they were 5-10 years ago you can still make enjoyable games.

> having a trusted compiler could (eventually) massively increase performance by removing processes entirely (no more virtual memory! no more TLB flushes and misses! less task switch overhead!) and eliminating the kernel/user mode separation

I saw a talk a while ago that was advocating for the same thing, except this was about JS and not webassembly. I can't find it tho - I remember it being related to the WAT js talk; It also mentioned that it would eliminate rings on the cpu (and simplify cpus) and context switches which would make execution faster; they were citing some MS research on the matter - damn I really wanna find the talk now...

thanks BoppreH

MS research: "Hardware-based isolation incurs nontrivial performance costs (up to 25-33%) and complicates system implementations" (virtual memory and protection rings); I think MS knows what they're talking about here

Tangential-ish:

I used to live in a place where we had gas resources and gas stoves. Gas pipes would be painted yellow to stand out and people always had some sort of respect and caution around them - you don't mess with gas pipes - I learned that as a kid. At the slightest whif of gas people would light up a match or a lighter and run it along the pipe to check for leaks - I always thought this is what "smoke testing" meant (altho there would't be any smoke). I still don't know if this is safe or would even work or it's just something people did and keep doing... and I have no gas pipes around me anymore.

I come back to this article every now and then http://www.loper-os.org/?p=861

How do you figure out they're using an engine? Are there obvious human moves and AI moves?

Yes - for whatever reason we really like to get our own label and wear it with pride. I would be very curious to find out if we actually try to fit into this newfound label if we knew about it from an early age. When I was young members of my family told me what sun/zodiac sign I am and kept explaining my behavior from that perspective - I actually enjoyed it and believed in it and (annoyingly enough) I now fit the description; wish I knew if this is pure coincidence or something I managed to embed within myself - there must be some studies out there on this issue

Was thinking the same - companies are extremely protective of their source code. How many games out there truly have unique/interesting/hard tech in them? I can think of Spore; I can think of a handful of rendering engines, maybe Stalker, Wow of course but not many more than that
