After a quick google I found someone had uploaded a remake of this with JS:

I implemented this as an XScreensaver hack a few years back: https://github.com/Acedio/mystical

Was hoping it would be included in the distribution, but sadly never got a response D:

Similar cross of art, low power/resilient tech, and sailing I saw at strange loop last year. Non-standard tech talk for sure, but fit right in at that conference: https://www.youtube.com/watch?v=T3u7bGgVspM

The presenter, Devine, is one of the folks behind 100r :)

This is really neat!

I made a space-filling curve:

[[[[[[[[[[[[[[[[FR]]FRR]]RRRRRRF]]FFFFFFFRR]]RRRRRRFFFFFFFFF]]FFFFFFFFFFFFFFFFFFFFFFFRR]]RRRRRRFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF]]FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFRR]]

It's not very interesting by itself (it just fills the whole screen with white) but you get cool-looking visualisations of its fractal-like structure by putting "C" at different points of the opening brackets.

Tried seeing how small of a program I could fill the screen with. Came up with this, but feels like there has to be a more elegant solution ^^;

[[[[[[[[[[[[[[[[F]]]]]]]]RRF[[R]R]]]]]]]]]

acedio commented on The Projectionist: On the best job that no longer exists   pipewrenchmag.com/the-fil... · Posted by u/samclemens
acedio · 3 years ago
I was a projectionist at a local 14-plex for a couple of years back in college. It was a really excellent job for getting homework done while the machines buzzed in the background. I miss the simplicity and meditative quality of threading the machines and keeping everything on schedule, and often find myself wishing I could retreat to a job like that again. The occasional brain wrap (or worse, a thrown film) always kept us on our toes, but otherwise it was generally low stress and gave me plenty of time to think about whatever hobby I was into at the time :)

Am I crazy or is the first answer terrible? I sat down and wrote out and answer for the problem and I initialized one integer and one timestamp. It should be O(1) time and O(1) memory easily, right? I'm seeing comments saying they'd use an array or a hash table -- why are you using any data structure? You don't need to remember how many times it was called 61 seconds ago; just keep a timestamp and the last time you reset the timestamp. If you need it to be clock-minutes instead of rolling (it doesn't; whose clock, anyway?), then just round the timestamp. The obvious follow-up question is "ok, what if it needs to be limited to 10,000 calls per minute?" You're going to keep 10,000+ elements in some collection for no reason? I wouldn't immediately reject a candidate for coming up with this answer but I would seriously question their thought process on this one.

In fact it's kind of ironic that his first example exposes how bad this advice is: by trying to meta-game, starting from a few example data structures, he shows he completely misses the solution that is both simpler and much more performant.

acedio · 4 years ago
That's a better solution in general IMO, but the author's approach can guarantee that you'll never go over N calls in a sliding window rather than fixed windows. I don't believe that's possible with the timestamp + count solution. Gotta bring up both solutions and ask the interviewer what they want :)

Reminds me of SimTunes! "Bugs" move around the screen according to simple rules, triggering notes as they pass over them. For example: https://youtu.be/DAluHrsCKxw

I'm not anti-bodycam at all - but they don't seem to have had the effect we all hoped for...

From a minute of googling, looks like San Diego had more dramatic results

From the article:

>> It's to be expected that these cameras might have little impact on the behavior of police officers in Washington, D.C., he says, because this particular force went through about a decade of federal oversight to help improve the department.

Seems as though the D.C. PD didn't have many issues that needed correcting?

I really like the animation, but I'm confused by it. I thought that the whole thing with chaotic systems is that extremely slight differences in starting positions lead to very different outcomes. The continuity of the gif is surprising.
acedio · 8 years ago
Could be wrong, but I believe the areas you're referring to as continuous are the areas where it takes a while for the first flip to occur (if it ever does). Once a flip happens, neighboring cells seem to diverge quite quickly.

How far into the video does TASBot begin?
acedio · 9 years ago
The actual play starts at 29:00 (https://youtu.be/Ukq29ePnTqI?t=29m00s), but the video streaming through the SNES starts at 55:50 (https://youtu.be/Ukq29ePnTqI?t=55m50s).

The way they did it was a bit confusing. They were playing Zelda, and then they cut the game off right as they walked through a door. Shortly after, Super Mario N64 popped up on the center of the screen. Twitch chat wondered if they were still playing Zelda and playing SM64 through the Zelda game. It wasn't clear what was going on, and they saved the explanation until the very end.
acedio · 9 years ago
Yeah, I think the effect would have been better had they explained what was going on immediately rather than saving it until the end. Very cool tech, regardless :)
