Recursion makes for elegant code, but in production code should be avoided. At least when you have no control of the input data. The reason is that there is a fairly tight restriction on stack size (you have to explicitly tell your OS that you need large stack). As a result you will coredump if your input is the right kind of nasty.
At least with ECC you'll get _some_ feedback (it's random so it will pop from time to time) indicating that something fishy is going on. With regular ram all corruptions are silent so you'll get random crashes that will drive you crazy...
I seriously doubt that difference in load is due to drive speed, at least not directly. Their pods are connected by slow (1Gb?) Ethernet. My guess is that there is a sort of interference effect between disk rotation speed, network data rate, buffer sizes, tcp window size etc.
Actually, as somebody pointed out, if you put any modern copy-on-write file system (xfs, btrfs etc.) on that puppy, SMR disk will work just like any other hard drive.
My guess, is that due to the way they write data onto platter, this drive is pretty much useless for random writes (even more so than a regular hard drive). It's good only for huge sequential writes i.e. just bulk storage. Knowing this, they, allegedly, added some long term reliability features and slapped "archival" moniker.
It makes 6TB WD Green way overpriced. Will be fun to watch price action on newegg.
These drives are targeting more or less the same market. And judging by the number of complains, WD's 4 and 6TB drives are not much better in reliability department (although I might be wrong in that regard)
The real reason is that google has failed to penetrate russian market.
They are cutting their losses, that's all. And considering that there are no prospects for business, there are no reasons to invest into infrastructure.
We're not talking about evolutionary change but revolutionary. Drop in parts number is so drastic that it allows for more competitors to sprung up (hence Tesla). The risk for established players is in going from oligopoly and into a commoditized market. And that hurts. Badly.
Basically, if democrats refuse to listen to us - this is what they'll get.
I'm as liberal as people get, but that NSA thing pissed me off so bad that I consider voting Republican.
For those, who say that Republicans will not act on NSA either, I say this: Listen, elections is what in game theory considered a repeat game. In such situations it's often advantageous to enforce beneficial cooperation by employing fear of retaliation. And we're not bluffing this time...
You do not need an AI capable to operate in the real/physical world to wreak havoc in it. All you need is some super smart out of control worm capable of penetrating a highly automated military defense system (e.g. "dead hand")
for western companies operating in Russia is to hire "logistics consultants" among locals who do all the actual bribing. It provides a degree of separation - a plausible deniability.
I would recommend explicit checksumming in data backup scenario. Main advantage is that this way your data is "multi-modal" (in shipping industry lingo). I.e. you can move your data between different computers, different filesystems and all the checksums move along. So when it's time to move your data to a newer disk you just copy it and you're not tied up with the choice of file system you made before. Scrubbing is easy too.
Plus you will not lose any files without noticing the fact - even when file is deleted it's still in your md5 file.
And you don't even need any scripts to handle your data - all decent filemanagers (e.g. "Total Commander" / "Double Commander" etc.) can do md5/sha/whatever on selected files on the click of a button.
Moron does not know what's he talking about. There are plenty of places in government where proper geeks work. Examples: NSA and NIH. All what it takes is the ability of the agency in question to pay market rates, e.g. "title 42" and such (both big Ns can do that).
That's bullshit. There were no bread lines in 80's (lines, indeed, were everywhere, but not for basic stuff). And Gulag for dissidents was practically over too (for casual rumblings anyway). Sure, it was a shitty place to live, but not for reasons you stated. Stop trivializing.
I'm in a scientific field, so here is my anecdotal take on it. Yes, I use Mac. No, I don't give a shit that it's a unix. No actual development happening with Mac as a target - everything is running on Linux servers (desktops are too puny). The only reason - Mac has better xserver comparing to what we have for windows. And IT guys refuse to support any kind of Linux on desktops.
Happened to me too! Had to call Comcast several times until got through drones to a supervisor. He confirmed that account was properly closed, said "what's the fuck?" and faxed me a letter to send to collectors. Also, it seems, he did something on his side too - issue got resolved without any blemishes to my credit history.
I know that this is not a purely gaming card bla bla bla. But here is another ping: in this month's graphics card review at Tom's hardware AMD totally dominated... in all categories. I mean a clean sweep! What's going on? Or is it just bad timing?
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).
I suspect it's more like a form of protectionism. They can't slap some serious tariffs due to WTO or whatever. So in order to protect fledgling local production they do a form of bang-bang control: now you can watch that and now you can't.

Oups. Yes, I meant ZFS.

The point was: how to remind democrats that they have to actually listen to us. Or else...

How is this any different from you going to the police right now and saying you watched your neighbour murder someone?

Actually ( and surprisingly) Swiss have bad reputation when it comes to all things crypto. Google "Crypto AG"...
Technically, the fact that a signal is below noise level does not forbid it's reception. GPS, for example, is below noise floor.
