@Longplay_Games I never participated. I don't even know what to expect, really...

Is it worth it? Especially with my limited time?

Kudos to SL for immortalizing it in the last FUCK COMPUTERS zine. I'm gonna stick it to the bathroom wall-of-fame.

The plan9front hack-a-thon held in Malaga Spain has ended with a recreation of the Bell Labs hot tubs shot. The hack-a-thon was quite successful and will be held again. soon.

#C64 #rétrogaming #raycasting #trsi #demoscene

TRSI (no less) did the most insane thing ever done in computer history.

Releasing a good looking, well playable #Wolfenstein 3D clone on the VANILLA C64 homecomputer from 1982.
This makes games people thought to be amazing like Quake, Half Life 2, the Metro games and what not just look silly from a technical point of view.

Computer #programming probably cannot get more optimized, more insane, more better than this. Ever again.
Because the control panels of your washing machine or your kitchen stove are pretty sure about magnitudes faster and more capable for this than a bloody 8bit C64 with its 0.98 MHz [PAL] clock..


@kl some time ago I started my projects with a new wikifs. It was easy to embed into acme, so it was a good candidate.

@neauoire @tty absolutely. I just like playing go and I have a pretty fancy go board (and nobody to play with, sadly)

@Trav eink has issues with too much sun light, but what about real-life solar-powered minecraft piston displays?

I've been playing Conway's Phutball a lot these past few days, I transcribed the rules on my wiki if anyone is looking for a fun 2-players boardgame.

@mwlucas you might have more luck with a more specialized arduino forum/chat, I can imagine. They're likely smaller and work on similar things.

@a btw following your explanation it also refers to the amount of "axes", basically. To build a 3d coordinate system you have three axes. To build these three axes you need (at a minimum) 4 points, etc. It also fits the explanation 100% and is even easier to explain, imo

@a ah, yeah, the term "space" here is very misleading... But I guess "field" is also similar. Maybe something like "system" (from coordinate system) or just "object"?

In 3d CGI, we know the term "object space" which doesn't refer to the object itself, but the coordinate system around that object (from the perspective of that object). So in the end, "space" might as well be just right

@a wdym 4 points describes a 3d space? A plane with 4 points in 3d space can not be visualized in only one way (that's why we use triangles in CGI). Or do you refer to the axes? (origin, x/y/z)?

And what should "visualizing 3d space in a 4d space" mean? I only know the projection of a 4d object into a 3d space (N to N-1).

@a that's quite obvious, but I'm still thinking about the 4D counterpart of a plane, or a "plane" defined with 4 points?

Math folks:
You need a minimum of two points to define a line and three to define a plane. Is the pattern simply N points to define a space of N-1 dimensions? Why?

Unless you were there, you really cannot appreciate how much damage Intel did to the PC ecosystem with the 286.


The 286 was the successor to the 8086 and 8088 CPUs that powered the original IBM PCs. It offered a huge step forward from them.

Those older chips always ran in "real mode," where memory locations had fixed addresses, and any running program could modify the contents of any address. This meant that you couldn't have two programs running at once, because one might try to use a bit of memory the other was already using, and blammo!

The 286 introduced "protected mode," which prevented programs from being able to mess with memory allocated to other programs. Instead of addresses corresponding directly to blocks of memory, in protected mode they were treated as "virtual" addresses, and mapped to memory allocated just for that program.

Protected mode meant the days when one program could reach into another one and mess with its memory would be over. And that opened up all sorts of possibilities. You could have real multitasking! A whole range of crash bugs would be instantly eliminated! Suddenly the PC began to look like a machine that you could put against a UNIX workstation with a straight face.

But there was a problem. To maintain backwards compatibility with the old chips, the 286 had to boot into real mode. It could then shift into protected mode on demand. But -- and this is a big BUT -- once it was shifted into protected mode, IT COULD NOT SHIFT BACK. The only way to get back into real mode was to reboot the PC.

Which was a problem, because every PC user owned a huge library of DOS software, much of which could only run in real mode. So the 286 gave you multitasking -- but if you ever needed to run a real-mode program, you had to reboot your PC (and lose all the other running programs) to run it.

This was, as you may imagine, not ideal.
