Such a link could be created automatically when you register for a car plate.

You comment deserves at least two upvotes.

I don't know this field of research thus my question: why such a high framerate is consider as a feature at all? Does it help with learning rate?

[Wingy → toppy]

If you have a simulation where realtime is 60 fps, you could simulate a little over 4.5 hours per second if you could run it at 1M fps. That would definitely help with learning rate.

[ramon156 → Wingy]

Feels like less ≠ more. If you want to fill in these gaps you might aswell interpolate

[mlyle → ramon156]

He's not saying "break realtime into microsecond chunks."

He's saying: run through 4.5 hours of 16 millisecond chunks of time in a second. This is good for regression testing or producing training data quickly.

On: The Endless Maze algorithm (Atari 2600)

[toppy]

For Commodore there is this classic recipe [1] for infinite maze:

10 PRINT CHR$(205.5+RND(1)); : GOTO 10

  python3 -c 'import random, time, itertools; any(time.sleep(0.01) or print(random.choice("\u2571\u2572"), end="", flush=True) for x in itertools.repeat(None))'

Note this doesn't guarantee passable maces.

[toppy]

The broader contexts could be this: look at this puzzle as a way for reinvent sorting as a delegation of operations (split + combine) instead of traditional "swapping" of values. As CPU arithmetic is faster then memory operations some real treasure may be hidden in this new approach.

[Thiez → toppy]

That is clearly nonsense, as the results of performing the arithmetic still need to be written back to memory, so it's just a swap with extra operations. See also the xor-swap.

Where's GitHub Fraud Detection Team?

[andreashaerter → toppy]

busy blocking the co-founder https://twitter.com/defunkt/status/1754610843361362360

[arp242 → andreashaerter]

That sort of thing happens because there's so much spam and malicious activity, such as the thing reported in this story.

That's it.

On: RR – Railroad Diagram Generator

SQLite diagrams: https://www.sqlite.org/syntaxdiagrams.html

[thomasmg → toppy]

The RR diagrams are images, while the SQLite diagrams are SVG. In my view, SVG is better: it allows copy & paste. SVG would also allow adding links directly in the diagrams, but SQLite doesn't have that (so far).

The diagrams for the H2 database [1], and Apache Jackrabbit Oak [2], do have links. (I wrote the generator for those.)

[umanwizard → thomasmg]

Not true. RR produces SVGs.

[o11c → toppy]

One major caveat for the SQLite diagrams in particular - they are written by hand, not from the computer-readable parser description.

This means that there are sometimes blatant bugs and ambiguities. Test your AST assumptions against a real SQLite!
