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?
Well, am an engeneer and a scientist.
And considering that arcs (as presented) do not have error brackets on them is a dead giveaway that qualifications of people who did the calculations are highly suspect.
Considering that the arcs are, well, arcs, I'll take a wild guess and say that they had data from only one satellite...
Some spy birds might help, but they tend to focus on land areas.
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.
Maybe D.B. Cooper style heist? That would explain weird altitude behavior: need to lower pressure difference to open doors, set on autopilot, and then jump while westward crossing over Malaysia.
Are you sure about this? I mean, if you're not planning for subsequent take-off then your runway may be much - much shorter. Remember, a few months ago, Boeing transport landed in a wrong airport.
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).
Disclaimer: All of the above is not written for stodgy "enterprise level" types.
This seems more like one of the successful KGB misinformation campaigns of the 1970s and 1980s.
Are you refering to that stunt when Russians claimed that a bunch of BBC's senior staff members were on MI6 payroll? For that case, current consensus is that it was actually true.
That's not what I was talking about. Full discharge is a bad and, well, extreme case. No, when people talk about cycles, they mean how many times battery supplied it's rated amount of energy. For example, if you drive to work 5 times a week and each time discharge 20% of your battery, you do 1 cycle a week (regardless if you plug it in every night or not).
This does not apply to Teslas for very simple reason: their battery is HUGE. So for the same daily routine, they will accrue 1 cycle not in a week but in a month (same amount of energy is now only 5% of the capacity)! Thus they burn through li-ion cycles at a much, much slower pace (and that's why, again, your Volt's battery is bigger than needed for spec'd performance - to slow down cycling degradation - just re-read my previous comment)
That the battery's calendar life that is a problem that affects everybody.
What's happening is that degradation is being hidden from you. Volt's battery is much bigger than needed for the purpose - they over-provisioned it because cycling of a smaller battery kills it really fast.
So as the battery degrades, cycles start to grow at faster and faster rate (even when you're keeping the exact same driving routine). So when that point comes that the car can no longer hide the overall state of the battery, your electric range will start dropping like a rock.
And my point was that when everybody will try to buy them, they would become either oversold or become really-really expensive.
Actually, regardless, money becomes an issue really fast anyway - few days ago Wired run a story that for many types of loads AWS does not make much financial sense anymore and people started to add two and two together. In other words - people are prepared to pay only so much (in a pinch a little bit extra) - ask a little bit more and they'll start to roll their own.
Saying that it's not a problem does not make it so. Besides, as soon as people learn to failover gracefully guess what would start to happen: other regions would begin buckling under load.
Actually, it's a rather common practice. Assumption is that with the exception of rare cases (i.e. Chechens), KGB (a.k.a. FSB) does not talk to FBI. So they are played against each other: Don't want NSA reading your stuff - tunnel to mail.ru (or such), don't want FSB - tunnel to gmail. Don't like both reading the same message - try Asians (and btw, you have some serious problems my friend.) I would not go with Europeans though - there were some nasty scandals in the past (even with Swiss of all nations)

How many satellites heard the pings?

Data from other planes will not help much - mostly only to set error brackets. The ill-conditioness of the problem does not go away.
And what if the sphere does not intersect earth? :)
Navy guys will need more data.

My T41 runs lubuntu 13.04 just fine. So yes, you can! :) Google for "fake-pae"

Sure, ZFS is alright too, but where's the excitement in that? :)

Actually, depending on how many clams were examined (and other things), odds of 1000s of similar age clams still out there might not be all that good.
There is a cool statistical result known as German tank problem
Actually, thin sheets of gorilla glass are fairly flexible.
It should be better at surviving drops. Part of impact energy will go into bending and not into shuttering stuff.

The first rule of diversification: don't put your eggs into correlating baskets.
In this context it means that if your primary is on AWS, then your secondary must be on Rackspace or whatever - NOT other AWS.
Apparently that Guardian journalist's partner was detained for 9 hours at Heathrow airport. That's a reason enough.
Wouldn't it incentivize Russians to disappear Snowden just to get to those juicy NSA files?
