Comment Re:So they want to make things worse? (Score 1) 85

It's not a term for which there is a "generally accepted" definition. It's slang, which is widely variable between sub-populations.

The general idea of "drone" is usually someone who's useless.
The general idea of "suit" is someone who dresses excessively formally.
These are both judgements based on the perceptions of the one doing the describing.

Comment Re:Next up: Swarms (Score 1) 69

If you think of it as a missile, you've also got a different idea than what I'm talking about. It's sort of a cross between a missile and a fighter that is designed to work in swarms, run by a "home base" that could be a large truck for small swarms of short distance versions. Imagine *highly* souped up model airplanes that are designed to act like missiles, if called upon. Long distance versions would probably always be more ammunition than craft (sort of like cruise missiles) for cost reasons, but shorter range versions would be expected to be refuel-able, and reusable unless the particular craft was used for an attack.
FWIW, I expect most of them to be relatively short-range, but too fast for the quad-copter design to work. Perhaps one model could be designed for "site defense".

Comment Re:Next up: Swarms (Score 2) 69

I don't expect swarms to use the same form factor as a fighter. Really I expect them to be a cross between a fighter and a missile. No guns on board, and no missiles on board. Yes, fly like a plane, and land safely back home if you can, but also the attack mode is to crash into the target (or get close enough, and explode). Size will (and design details) will be dependent on desired range and speed.

As a result, each individual craft will be a LOT cheaper than current fighters. But a swarm may well be even more expensive. (Depending on swarm size and desired range and speed.)

Comment Movies have become more derivative every decade (Score 1) 100

Movies have become more derivative every decade since the motion picture camera was invented. This is the "low hanging fruit" observation.

People only have a certain number of desires, and only desire a certain amount of change. As it gets more difficult to come up with something new that people like, something old will get repeated more. As there gets to be a longer history of "something old that people liked", something new will be created less often.

It's not just movies. You can see it everywhere. Consider, e.g., software. A new edition has to change something noticeable, but it gets harder to come up with something new that people will like as much.

Comment Re:And they wonder why people pirate (Score 3, Insightful) 136

That is, indeed, the most ethical. It's the way I chose. But I never deluded myself into believing that it would alter the behavior of the companies. Only two things (that I've thought of) stand a chance of doing that.
1) If you stop selling something that you are the monopolizer of sales in, you lose all associated copyrights. (And possibly all associated patents.) I.e. legal action to make things that you buy act is if they are yours.
2) Massive community on-line attacks whenever a company disables something that it's sold.

I don't think either of those have much chance of happening, and the second would be quite dangerous.

Comment Re:I've always felt the great filter (Score 1) 315

There's probably no "the" filter. It's probably a raft of multiple pieces. Some species won't be able to survive away from their home planet. Some will be aquatic (or other heavy medium). Some won't be able to tolerate the communications lag time. Some will kill each other off in suicidal war. Etc. Etc. Etc.

And another part of the filter is, since FTL appears to be impossible, (if only because of collision with grains of dust) once you've spent thousands of years in space, that's what you're adapted to, and then you don't want to (or can't) visit a planet.

Comment Re:"United States' dominance in space" (Score 1) 196

There were contributions from multiple countries. You can point to particular problems that the Russians solved, but also some the the folks in the US solved. And the Germans. (And, IIRC, the French.) If you go back far enough, most of the progress happened in China.

For that matter, I suspect that in the 1700's much of the progress happened in Britain. (Consider "in the rocket's red glare", and there was a lot of work on rockets between ships...often for carrying a line to allow a rescue.)

>If you think that stack size depends on the algorithm

I said stack size depends on the data. Data dependent timing and memory use are gifts to the side channel people.
Not always, but you know that.

>Besides, tail calls are not the only form of recursion that can be optimised.
Yeah yeah, I did the algorithms course 35 years ago on recursion optimization in functional languages (Pre Haskell - We had standard ML and similar stuff back then).
You are arguing for correctness of code over side channel cleanliness. Correctness can be got at many ways. Data-runtime independence is not achieved with a recursion everywhere approach. You have to consider every case. Blanket "recursion everywhere" rules makes you sound like an FP zealot.

>your for-loops end up being compiled to recursive code,
Is your compiler drunk?
