Comment Huh? (Score 1) 237

GRBs clearly haven't prevented life in *our* galaxy, so the Fermi Paradox still stands.

The caluculations probably rule out life in the core of our galaxy, but systems further out would be exposed even less often than ours is. And even though GRBs can periodically sterilize a planet, their directionality means that one burst would not likely sterilize all the planets in an intercellar civilization simultaneously.

So, to modify what someone said above, we can add another term to the Drake equation, but this doesn't do much to answer Fermi.

Do you trust them?

...less than any other ISP? No. Just like Google funded Mozilla this is more of a long term effort to push more people and more services online, where Google can get a piece of it. The "old media" advertising budgets are still pretty huge and people willingly sign up to Google's services so there's no need to get shady. In fact their roll-out is extremely slow if they were seriously intending to become a major ISP, they're really just trying to shame the rest of the country into demanding they get the same kind of service from their incumbents. Who needs cable TV when you got gigabit service and can watch any show, any time over streaming without hitting any caps? That's what Google is selling, of course it's out of self-interest but for tech geeks I think they're on our side in this case.

If you think weather forecasting is easy, let's see some of your forecasts. A forecast which has been substantially correct for New England and merely didn't extend as far south as had been expected only underscores the difficulty of the exercise. Occam's Razor suggests that no cause beyond "honest mistake" need be posited. I know some people like to take every opportunity to prattle on about government overreach, but you're *really* stretching that fabric too thin this time. Get a grip.

Thats pretty much irrelevant. GPU ram isn't used that way at all. Its used to hold the 3D geometry, bitmaps, bump maps etc of assets and other processing data which is largely if not completely independent of screen resolution/no.of screens.

For real-time rendering of a simulated environment - that is, gaming - textures are generally stored as mipmaps so the more pixels it's going to take up on the screen, the more detailed version of the texture is used and thus the memory use rises accordingly through the entire pipeline. It's pretty easy to see if you keep resolution or texture quality constant and vary the other. If you're doing some other kind of simulation that might not hold, but for gaming what you said is pretty much false.

Hey, I'm still happy about my purchase but when I bought it I looked at the specs and thought: Hmm, they've disabled 3/16ths of the shaders, but it has the same ROPs, same cache, same RAM... if I buy two for SLI it should perform like the GTX 980 except for having 2x13 = 26 shader blocks instead of 16/32 for a single/double 980. Now I find out that's just not true, it has 0.5 GB quasi-RAM it can't access at the listed memory bandwidth, I feel I got very legitimate reason to feel cheated.

Apparently the ROP/cache isn't a big deal at it makes sense to use 7/8th = 14/16th to serve 13/16th the shaders, if only they'd listed the specs right. But gaming at 3840x2160 with SLI there's a fair chance I could run into a game now or in the future that wants to use all 4GB where it'll either act like a 3.5GB card or drop the framerate significantly underperforming compared to the GTX 980, I don't think that's just theoretical.

I'd probably still be quite cool with a 3.5GB card with 0.5GB of "last resort" memory that's still faster/lower latency than system memory. But they were in error and have admitted they were in error, I think that goes a little beyond "We said we're sorry" Paying some kind of compensation for falsely promised functionality would not be unreasonable (or swapping my GTX 970s with a 8-channel memory version, but I guess that's overkill). I'd be very surprised if there isn't a class action lawsuit very soon.

Comment Re:We Really Don't (Score 1) 153

Sorry... I was going for the joke and didn't pitch it very well. My actual views are more like yours.

As for the reality of the subject matter, I would borrow the concept of "probably approximately correct" from machine learning, and give it a 90-95% chance of being ~80% correct. (The 80% is lower to allow room for some more big discoveries like inflation.)

Unfortunately, people will be (hopefully) studying this for thousands of years on top of the <100 we have so far, and none of us will live to see how it turns out in the long term.

Heads are also heavily protected. Have you never seen the gear SWAT teams, riot police, soldiers, etc. wear? You really think they walk around with their head exposed?

Since those guys are likely to be in full heavy body armor as well and humans need to see and breathe the face is still the weak spot, unless you got a high powered rifle or something. Not that you're going to win against a whole SWAT team anyway, but one lone nutcase who has you backed into a corner... I'd aim for the face.

PGP/GPG is much easier to use these days than it was in the 90's. Plugins exist for many mail clients that do the heavy lifting in the background.

Friends and family are surely tired of my tinfoil hat, they just do not seem to care about their privacy. Many say the "I have nothing to hide" line.

SpaceX will sell the Air Farce the rockets. The AF launches their gear into orbit. SpaceX has nothing to do with it more than to get paid for the hardware and some support personnel who will have to have security clearances.

These aren't just slightly confidential, state of the art spy satellites is top secret business. They'll be worrying that a SpaceX employee can plant something to steal technology, reveal capabilities, damage or compromise the satellite once the payload is installed. I'm guessing you need just a microscopic amount of C4 if it can hook into the antenna and wait for a self-destruct signal so that when you need them the most they go boom and the screens go dark.
