Comment heat (Score 1) 340

While there may be no mass escaping from this device, it absolutely is consuming energy. Where does that go?

In most of the mundane pursuits we understand, it goes to producing heat. In physics, one fairly valid viewpoint is that heat is motion, in that a "hotter" result has more motion activity going on at the particle level.

One of the reasons that perpetual motion is impossible is that within a closed system, we can't make anything 100% efficient. Typically the lost percentage wanders off in some fairly easily identifiable thermal guise.

The first thing to keep in mind is that not all energy expended does useful work.

But that's not really the problem here. the problem is that motion in space, as we understand it, depends entirely on imparting momentum to something. The only way we have practically been able to do that is to send stuff out one end of a spacecraft, which causes, due to the equal and opposite rule of newtonian physics, the spacecraft to go in the opposite direction.

But it's not really about "where does the energy go." This thing is being sold as "doesn't send stuff out one end of spacecraft" and "imparts momentum." The physics folks are looking at that claim very dubiously, because so far, there's no generally accepted science that could account for such a thing.

If it turns out to be a real effect (and I'm not saying it will), then we're going to have some new science to learn.

Comment science fiction, fantasy, etc (Score 2) 340

...science fiction I read when I was young ... violates laws of physics big-time.

Then you were reading (very likely mislabeled) fantasy. The whole point of science fiction is to embed a story within the context of plausible science. Nothing wrong with fantasy, but it isn't, and never has been, science fiction.

Between the "speculative fiction" rendering down of that specific distinction, and the marketing-driven labeling of fantasy as science fiction, and the tendency of bookstores for decades to lump fantasy and science fiction together, your experience is the rule, rather than the exception.

But there's still science fiction being written. The trick is finding it.

Yep and I'll be advising customers to disable updates, which won't be an issue since the browser runs in a sandbox and all web pages are scanned before load.

Meanwhile all my business customers are looking at exit strategies, some looking at Apple, some looking at Linux with a Windows VM for the Windows centric software that is required. All MSFT is doing is shooting themselves in their face with this dumb shit because a desktop is not a cellphone and the shit people will put up with on a cellphone the majority will NOT put up with on a desktop. I should know as uninstalling windows 10 is frankly one of my most popular services, it even surpassed Win 8 uninstalls awhile back, its just too fucking buggy.

Here is a good example from the bad old days, new games aren't USUALLY this bad but I chose this because its rather easy to see the pop in...notice how it looks like the path ahead is clear then suddenly mountains and other terrain just magically appear in front of the ship? That is pop in which is caused when a game for whatever reason is simply incapable of rendering in objects before they come close enough to the player for the player not to notice their being drawn...THAT is pop in and its irritating as hell and pretty much kills any sense of immersion in the game world.

Comment Re:It's Sony - duh (Score 1) 463

Bullshit as from all reports it would take quite a bit of time to get towards the center (where the devs said in interview after interview was where all the faction system and battles would be taking place) only to find...its not there, its all been ripped out or was straight up vaporware.

At the end of the day? No Man's Sky is fraud, plain and simple. in interview after interview, some being given mere DAYS before release they touted features that did not exist and showed content that simply did not exist in game. Since the game has procedurally generated worlds? Its quite possible you get started on some shit world where it takes dozens of hours to gather the resources required to get really up and running just to find out all those features, the faction system, big space battles, planets where you have day/night cycles and weather based on its place in the system, an economy where you can be a trader or miner or make runs for various factions....they just do not exist.

A the end of the day I see NO difference between this and Aliens:Colonial Marines. In both cases you had devs showing content that didn't exist, hyped features that didn't exist, and the footage shown turned out to be bullshit. Sorry but they deserve a refund if they ask for it because at the end of the day what was shown and what they got? Couldn't be more opposite.

Comment I'm quite ignorant of the KKK (Score 1) 2

All I know about them is they hate blacks, Jews, and Catholics (presumably all non-protestants, but as I said, I'm ignorant). What views do they have that aren't hateful? I'm curious.

As to BLM, the entire reason that movement HAD to happen was because there really ARE people who think black lives DON'T matter, including black gangsters and bigoted whites. You have some citation for BLMers advocating hatred or violence?

Like the late humorist Will Rogers said in the 1930s, "all I know is what I read in the papers" and I have a LOT more newspapers available than he did, thanks to the internet.

Also, there is caching, and also, some loads are heavy on longish FPU operations.

So... it doesn't quite work out that way. Also, multicore designs can have separate memory.

One example of multicore design that's both interesting and functional are the various vector processor graphics cores. Lots of em in there; and they get to do a lot of useful work you couldn't really do any other way with similar clock speeds and process tech.
