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?

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.

I tend to write a lot between the lines. Here's the one of the lines I skipped: in COW setups, in stable state you write at exactly same rate as you free blocks. I.e. by writing 1 gig, you're freeing 1 gig. And so on to the end of block space, then you wrap and repeat. Wear leveling is additional side effect.

Well, if you don't do random writes, you don't need TRIM.

How to get away from random writes you ask? Simple! Just use BTRFS.

"But my database!" you say. Well, the answer is simple - time to move away from 50 year old technology and to a modern database engine, the kind that doesn't do random writes either (fractal tree based, for example).
