Realtime means different things in different contexts. If I can watch a webcam of freeway traffic, than 5 seconds delay is, for all intents and purposes, realtime. If we talk about medical equipment, it may be very different based on the eq

Well, I much prefer people mooning each other, or, similarly, the actual happenstance of countries voting for and against each other in the Eurovision Song Contest for reasons other than musical merit, to armed conflict.

That would be fun. How do you imagine the “ring”? A huge part of the appeal is that both sides can see each other.

OP is correct, 1/30 s is a good ballpark theoretical lower bound. Assuming travel across the earth surface, light in a vacuum take about 14ms to cross the distances. Times two for round trip that’s about 1/30 s. Of course we don’t

Well, yes, but you didn’t, did you. Come on, it does not take long consideration to appreciate how this can be interesting, even if the technical requirements aren’t interesting in themselves.

Presumably because they are of a previous location of the art’s installation. The article is written in future tense, so it stands to reason that there are no (interesting) pictures of the new installation yet.

Oh but that was specifically what I was trying to get at, i.e. point #4 of this reply of yours: Are there any shortcuts that make this reasonably computable or not? In your original reply, you started with (transcribing) "Kolmogorov

Oh, I think just fixing the original comment would quite likely have netted you upvotes, if there wasn't anything else wrong with your comment. I think downvoting because of an obvious typo is pretty dumb in the first place.

While reading your comment, I kept having the vague feeling that your idea of "theoretically computable" (within the given memory bounds) will still leave some exponential time and/or space complexity, and so effectively will

Complex numbers you just go sideways as well, and if you multiply you not only stretch or squish your path to the origin, you also change your angle to it by adding both angles together. Exponentiation is then doing this continuously, so yo

Besides, they’re really not that scary once you get to know them well. Take a deep dive into digital signal processing for example, and you become well comfortable with them, and understand how “the real world” fits into them quite neatly.

A model that is able to perfectly describe and (more importantly) predict everything is effectively indistinguishable from “reality”. Yes, there might or might not be a completely different, and maybe even weird, process underneath that giv

The majority of these 16384 bytes could be zeroes. They fill a single page, and if so, the only use you could make of those other ~16000 bytes would be to fill it with other code and/or read-only data for the same program, which just w

You’re right, so I was careful to say “s/360 lineage”! However, I thought a lot of the advanced concepts already were in some s/360s. Maybe not virtual machines, but that’s more the cherry on top (and pretty wild to me that s&#x2F

Do note though that they are both very different from s/360. Complexity-wise, 1401 and PDP/1 are a bit closer to home computers of the 80s, in that they usually just execute code in a single thread and context and without any prot

I thought about CPUs with either discrete transistors, or with e.g. 74xx ICs. But the former intuitively seemed too big to me (because I was assuming they use large transistor packages instead of SMT), and the latter too small (because a si

The software is really not an issue. I saw the MOnSter 6502 live running BASIC, and it was MS BASIC as far as I recall. It just wasn't simply hooked up as the CPU of an Apple II or similar.

And had much larger "nodes", given that those tubes are much, much larger and farther apart than the SMT transistors on this 6502 replica. It's not even close. But I think IBM's SLT from the 1960s might come close: http

The fun path would be to modify the display to run at 3Hz (and also implying the much slower horizontal scan rate), but due to the phosphor coating's short persistence, you'd at best see only a small sliver of the full picture at

Again, the answer is almost certainly no, unfortunately. A Laser 128 isn't that fundamentally different to an actual Apple II. In fact, from a wider point of view, they are "almost identical". DRAM needing timely refresh is u
