Result of Nvidia's crippling DP floating point performance on mainstream graphic cards is people started to look for ways around this bullshit.

Case in point: linear algebra libraries (like 80% of scientific computing). Basically people are modifying algorithms so that bulk of computation is done in single precision and then cleaned up in double. Those mixed mode algorithms often outperform pure DP ones even on non crippled cards (for example MAGMA library).

People don't like to be screwed with...

Am I is the only one concerned about amount of RAM?

I mean, everybody is so excited about DDR4... But do people understand that instead of 8 dimm slots we'll get only 4 (1 dimm per channel instead of 2-3)? So while keeping costs on this side of reasonable, we're getting only half the amount of memory?

WTF?!!

Navy guys will need more data.

Those much hyped arcs from Inmarsat are pretty much bogus. The trouble is that the problem is badly conditioned - because satellite is way too far (geosynchonous orbit - not your friendly neighborhood gps) and it's right on top of the search area. In other words - small errors in time/distance measurements, satellite position, etc. produce huge errors in estimation. They're lucky they placed the airplane on earth.

For all those morons calling Snowden a traitor: consider this scenario.

Reviewing circumstances of that Petraeus scandal in the light of Snowden's revelations, it's pretty clear that NSA knew about CIA director affair, and more importantly kept the fact to itself (if, of course it wasn't a parallel construction by FBI, which is easy for them to check)

Now what we have? We have that NSA had dirt on a top CIA official, a popular political figure, with very probable presidential candidacy on the horizon. And what it did with that info? It kept it's chips to itself to cash-in at the most opportune moment! And the whole infrastructure at the NSA is built in such a way (intentionally!) that unless NSA wants to, nobody can say with absolute certainty what they knew and when they knew that.

In my books that is a direct threat to the republic.
