It's an ugly and stupid computer and the "display" is barely visible. It also doesn't have a cache, or MUL/DIV/MOD instructions. Not very impressive. It wasn't even actually made in the Game of Life. Also,

I once made a small x86 asm program that generated an image with a similar technique, except with 1-bit colour. Instead of x ^ y, it was parity(x ^ y), i.e. if there are an even number of 1 bits, colour it one way, else colour it another. I

To the people trying to be pedantic: Yes, computers really always do what they are told. The only complication is that sometimes they are told what to do by a cosmic ray.

Some people are pretty negative about the code presented here (which the author criticised in a second post[0]), which makes me wonder, as someone who thankfully hasn't programmed anything non-trivial in Javascript in years: Is checkin

I'm British. I only have a very vague memory of the game from my childhood. I didn't remember what the goal was, but I remembered you have to hit the opponent's one. I don't remember if I ever played it or not.

Oh yes, I really was missing something obvious. And you did, too, since I mentioned the architecture in the first line of my post.

I thought you were right, but I tested it on x86_64 GNU/Linux with this struct: struct ts { int32_t dword1; int64_t qword1; int32_t dword2; }; Writing -1 to all 3 members and printing ou

I'm typing this comment on Lynx in the Linux framebuffer console. I think trying to solve the problems of the web is an exercise in futility. The standard (or more accurately, set of standards) is too complicated to independently re-im

Hmm. I wonder if this is the distinction between people who prefer old Minecraft and new Minecraft. How do you feel about modern Minecraft?

I'm almost surprised nobody mentioned beta 1.7.3 yet. Some people, myself included, consider it to be the last good version of the game. It came before the adventure update, beta 1.8, in 2011. To put it simply, 1.8 is the inflection po

Why does making the FETCH part of the cycle a macro make it faster? Surely the branch predictor is fine with unconditional immediate branches. What am I missing here? Also, it has jump-to-register immediately after the instruction that sets

Where did he say this? In any case, I can confirm it from personal experience. x86 isn't that annoying if you ignore most of it. The worst thing is the edge cases with how some instructions can only use some registers, like shifting&#x
