Why would you doubt it? ZFS with its checksumming was designed specifically to detect and correct bit rot. If you have redundancy (MIRRORING or RAID-Z), it will automatically repair bit rot as soon as it detects it.
You're not limited to a big server to run ZFS. Yes, it gives you a whole lot of advantages if you do, but you still get the massive benefit of data checksumming and incredibly good power loss data protection even with a single disk.
Actually, because of its design, notably the COW principles, ZFS shines in its resistance to power interruptions and system crashes. I have a 36 TB ZFS server and a 21 TB ZFS server. Both run 24x7, no UPS, and have ridden out quite a few power interruptions over the years, with never a bit of data loss. Reboot requires no fsck. ZFS doesn't even have an fsck. It is IMPOSSIBLE for it to get corrupted. The most you can lose is some very recent data that was in the actual process of being written out at the moment of power interruption. All that happens is that the volume state gets rolled back to a few seconds previous, with complete consistency.
I experienced a horrific complete volume data loss with XFS under the same conditions. I will never use that garbage again.
BTW, ZFS compression does not use significant RAM. Dedupe, on the other hand, DOES. It's virtually never a viable option; CERTAINLY not for a home user who does not have HUNDREDS or THOUSANDS of GB of RAM in his server.
Cathode ray tube tubes, bwahaha. Automated teller machine machine[*]. Personal identification number number. Global positioning system system. Graphical user interface interface.
[*] BTW, isn't ATM already redundant? How could there be an automated teller that is not a "machine"?
PHP and ASP are server side. Yeah, they can use GET and POST, but they are not necessary to the use GET and POST. Any HTTP client "supports" HTTP generated by PHP and ASP.
BTW, SSL support in dillo is only an alpha prototype plugin. It does no cert caching or authentication.
The first time I looked at that URL (all lowercase, as in TFS)
Domain names are not case sensitive (RFC 4343). The remainder of the URL may be (and frequently, not not always, is), depending on the host software. This is also true for SMTP addresses.
Good point. However, wherever the fish you eat do come from, bioconcentration is most assuredly taking place. That is also true for plants and land (farm and wild) animals.
in my country the legal limit is 0.5, and I personally don't feel anything at or around that value
Permit me to doubt that highly. What is your country? Are you sure the limit is not 0.05%? That little dot is called a DECIMAL POINT, and it MATTERS where it is in the train of digits. At 0.05%, one feels euphoria and has impaired concentration. At 0.5%, there is a high risk of poisoning and death.
You're making it needlessly complicated. It IS unitless because it is a ratio. Blood alcohol content means exactly what it says: the mass concentration of alcohol in your blood. If it is 0.21%, it means 0.21% of the mass of your blood is alcohol. For example, an average human has right around 5 liters of blood in his body, which is about 5 kg of blood. If his BAC is 0.21%, his blood contains 5 * 0.21 / 100 = 0.0105 kg, or 10.5 grams, of alcohol.
Some googling show me that the legal limit in Indiana is 0.8 percent,
Get your eyes or your brain examined. The legal limit in Indiana (and in most places) is 0.08%, not 0.8%. At 0.8% most people would be unable to sit upright with their eyes open, let alone safely operate a motor vehicle.
The president can not make a ban based on religion
The President can make a determination on who gets to immigrate based on ANY CRITERIA WHATEVER. He doesn't HAVE to let ANYONE immigrate. That's a legal fact. Sorry to intrude reality on your sorry delusion.
The Ninth Circus arrogated a power they do not have. Proper response by the President would have been to call them out on it, defy their bullshit ruling, and prepare to take action against them for violating their oath of office to protect and defend the Constitution. The executive branch controls enforcement. Not the judicial.
What are you taking about? Zn is a metallic element with an atomic number of 30; the first element in group 12. Didn't you ever take a carbon-zinc battery apart? You get a zinc can (anode), a carbon rod (cathode), and a bunch of yucky pasty electrolyte.
Linux xxx.yyy.com 2.6.35.14-106.fc14.x86_64 #1 SMP Wed Nov 23 13:07:52 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux I'm operating at the bottom of the ocean and everything still works.:-)
Whoopdedoo. Linux 2.2 still works fine AT THE BOTTOM OF THE OCEAN. Not much of an attack surface exposure down there. There are plenty of Windows XP boxes in labs, with well-controlled access and no exposure to the internet, doing in-house work, un-patched for many years and without any anti-virus, that are still perfectly reliable.
It is extremely unlikely, that a second disk will randomly die on you during those few hours it will take you to replace the first one with your cold spare and for the array to rebuild.
Utter bullshit. The second drive will not fail "randomly", but through the torture of the rebuild process. Single-drive redundancy like RAID5 is just a good way to lose 100% of your data instead of some of it (individual separate drives). It is BARELY better than non-redundant RAID1 spanning. I don't trust it at all for anything that matters. I don't even think double redundancy (RAID-Z2) is due care for data. I accept nothing less than triple redundancy (RAID-Z3).
I remember it well. I was 18, an EE freshman at Northeastern at the time. I also remember Shepard's Freedom 7, the first suborbital manned rocket flight in 1961, I was in junior high school. And I remember seeing reports on the Korean war in the newspapers (I remember lots of things from kindergarten and first grade). And I vividly remember at age 10 breaking my piggy bank and having my dad take me to Radio Shack on Commonwealth Avenue so I could buy a CK-722 germanium transistor and some other components at the will-call counter. It was a pretty big (by later standards) silver-colored prismatically-shaped plastic package. I made a single-transistor radio from it using a schematic from Popular Electronics. I twisted the wires together because I didn't have a soldering iron.
It was almost certainly an ST412 10MB. I had one of those. The ST506 was the 5MB. It was slower than grass growing. The 412 was a hotrod in comparison.

Good luck doing an HTTP GET, or fetching any kind of data from the internet if you can't transmit packets.

That poor guy!
You keep using that word. I do not think it means what you think it means.
Idiot article confuses TB with Tb. So does the Toshiba press release. Morons.
Where any normal person is perfectly happy to have it rest forever.
News flash. Nothing in the deepest ocean trenches has any effect on the human food chain.
Or, expressed more rationally and clearly, 1 ng * g^-1 = 1 ppbm (part per billion by mass).

Even 0.04% results in impairment, by the way.
Masterpiece of understatement. That's APPALLINGLY, knee-slapping-laughably low. 1/500 as much as diesel fuel; 1/18 as much as a flashlight battery.

So the unlimited plan is NOT unlimited. Filthy lying bastards.

Oy vey. That brought back memories. I still have one sitting on a shelf, monument to failure. Beautiful elegant-looking trash.
