When will banks learn, if you make a vault, someone can break in.
And that's why you do not leave the vault unattended and have additional security so that nobody unauthorized can come near the vault. Otherwise it would be a matter of time before someone burned his/her way to the cash.
The same can be applied to movies. Place all existing copies of the move to a secure location, so that no one can come near it and nobody will be able to copy your movie. Nobody will be able to watch it either...
SATA drives are commonly specified with an unrecoverable read error rate (URE) of 10^14. Which means that once every 100,000,000,000,000 bits, the disk will very politely tell you that, so sorry, but I really, truly canâ(TM)t read that sector back to you.
So, the array will know where is this error, and the error will most likely be contained in a single sector. Yes, if the bad sector was in the file system structure (for example $MFT, or the FAT (but it has a second copy)) or in the middle of an important file (and software could not correct it) then you are out of luck. If it happened in unused part of the disk, then you would just have a few kilobytes of unusable space (because most likely the system would mark the sector as bad).
But the chances of it happening and being a really uncorrectable error are lower than 1 in 12TB
One of my old drives runs at 3600RPM, and there were others which run at 5400RPM (I think the newest version of Quantum BigFoot was 5400RPM). It seems that 5400RPM is the max, but at 5400RPM the edge of a 5.25" platter is traveling faster than the edge of a 3.5" platter, rotating at 7200RPM.
I don't really need a fast high capacity drive (I can use 36GB 15kRPM drive for the OS and a big slow one for everything else), so I could live with 40ms seek times and, say, 40MB/s linear read if that meant having a cheap high capacity drive.
I have a very old Seagate drive (well, it says Seagate ST41200N on the top, but windows recognizes it as Imprimis 94601-15). It is a 1.2GB (991MB) 5.25" full height drive and it works perfectly. I have another one, a bit younger (ST34520N) ~4GB, it also works very well. All the new ones also work well, so when I buy a hard drive, I buy Seagate.
I wonder why nobody is making 5.25" hard drives anymore... With current technology they could have at least 10TB capacity...
wow, then I should go and buy a lot of lamps before they disappear from the stores. I don't really care about lamp efficiency (yes, I would save ~30W if I used a CF lamp instead of that 40W incandescent, but my PCs use >1kW so those 30W wouldn't be a lot) and I like incandescent light better (yellow instead of white).
Battery UPS in your PC case...
And who is going to pay for that? Me? Why? I already have a big UPS for power outages.
More efficient solar energy.
If it is going to be cheaper on a small scale (up to 15MWh/year for me) than what I get from the grid (~0.1EUR/kWh) then I am all for it.
...if millions of homes participated.
And why would they participate? Would they get cheaper electricity if they do?
I am all for cheaper electricity. Solar power is too expensive, so I am using power from the grid. But If I find out that coal or whatever is cheaper then I do not really care about the environment. (I think that using coal/gas for electricity would be cheaper than power from the grid, but only if I used it in winter and used the waste heat to heat my house).
I used this. Not so for the security (I think a 63 character really random password would be enough), but for convenience - it was easier to copy two files (user certificate and CA certificate) to my cell phone than type ten 63 char password (which for some reason was reset after each phone reboot)...
Now I do not use wifi for my local network. For some reason the AP usually failed to authenticate users, so I scrapped the idea and now use the same AP as a client to my ISPs wifi network. It works now...
While I am not your average user, if there were no internet connection where I lived (but I could "see" a wireless network) or the only available was quite bad, I would get that which was available and then wait years until the wireless network was cracked.
Thankfully, I have a quite good internet connection 2x (4096kbps down 768kbps up)(two connections - one ADSL and the other free wireless from the same provider), and also see a lot of OPEN networks, one has a very good signal strength and it is my "unofficial" backup connection. If that also fails, there are about 20 more available once I connect a 7db antenna to my laptop or access point.
It tells windows to read a registry key called "HKEY_LOCAL_MACHINE\SOFTWARE\DoesNotExist" instead of autorun.inf file (when such a file exists). Since the key does not exist, windows thinks that the autorun.inf file is empty...
... And of those, only a few hundred of these went out, and it's not like the virus was running - it was in the deleted items...
Except that all autorun.inf viruses that I saw (on a USB flash memory) used \RECYCLED to store their executable, and the.inf file would look like open=\RECYCLED\desktop.exe
Even if you disable autoplay with group policy, the autorun.inf file will be read during startup, if you leave a CD in the drive or the autorun.inf file is on a hard drive...
Maybe sutorun was convenient before recordable CDs were invented. Even then, sometimes it was a PITA. For example - I start a game, it prompts me to insert the CD. I insert it and the game begins. Also, setup is launched automatically.
What is more stupid is that there is no "easy" way of disabling it, you have to hack the registry or autorun.inf file will be read even though autoplay is disabled (it will be read on startup, if you leave the CD in the drive or the file is in a hard drive or a USB flash memory that was left in it's port or was plugged in before windows started up.
It is possible to use the registry to instruct windows to read a specific registry key instead of a autorun.inf file. the "specific key" should not exist, only the autorun is truly disabled. Also you can disable autorun.inf this way and leave autoplay (that is starting a already installed program to handle the cd or whatever).
But I may not trust files on a CD or a USB flash memory. That stupid idea was introduced with windows 95 (I believe), and on windows XP it is very hard to disable (there is no way of just selecting "do not read autorun.inf file", you have to hack the registry to do it (just disabling autoplay in gpedit.msc will work only on media that was inserted after booting windows).
Since you are downloading the game for free, you already have a better version than the people who paid for it. You didn't pay any money, didn't have to wait for the CD/DVD to arrive in mail (or to the local store), and most importantly - you have no problems with DRM and your copy of the game will work 10 years from now.
Is it possible to do this thing in reverse? That is to access IPv6 network while my LAN is IPv4.
And no, I do not want all of my network devices to be accessible from the internet. If I want to access them, I use VPN (while it requires configuration, it also makes it impossible for anyone to connect to my local network without me giving them permission (and a certificate)).
Of course, I want certain applications to be accessible (like Bittorrent), that's why I use port forwarding.
Also, not everyone needs an external IP address. For example: a small company that uses internet only for web browsing and email. They now have a NAT router with no ports forwarded. They could even be under the ISPs NAT and would not feel a difference (although they have a single public IP).
Why would I want to use NAT even if I had to use IPv6 for my local network? Easy - so that I can hide the number of PCs I have connected to my network from my ISP. All they would see is a single IP in use...
About NAT hole punching: how do you do it without any help from the inside? If you can't then NAT is a very good security measure (like a firewall, deny by default)
I'm sure some people that don't know anything about IPv6 will reply, saying "oh, that's not actually IPv6!" They're wrong. Granted, it's not end-to-end IPv6, but that's not actually needed to reap some benefits. If you have a 6to4 address, and I have a 6to4 address, our respective routers will send IPv6 packets over the public IPv4 internet: no tunnels, no suboptimal routes.
How many "average" users use VPN or SSH? My friends only have a need for external IP address so that bittorrent works better. And if they do not use BT? No point in having a public IP just for email and web browsing.

32bit Windows XP also supports NUMA, otherwise I would not be able to use my PC which has 2x Opteron 270, each socket having its own memory.
Windows 2000 or NT4

Skip the BD player deal, buy the Disc at retail and then download their platform shifted unencrypted movie backup through P2P*.
Until you find out that it is also possible to skip the "buy the Disc" part.

I do not know much about RAID, but if the read error occurred during rebuild, wouldn't just that sector/cluster be lost and not the entire array?

And it also looks better to write "200GB" on a LTO-1 tape and then add the fine print on the other side of the box (assuming 2:1 compression).
Can anyone explain to me how this "tradition" (of writing double capacity) came to be?

EU just made incandescent lights illegal.

Looks like fun (would look like more fun if my eyesight didn't suck). Maybe I'll try it sometime...
So, if I want to play Counter-Strike, I and my friends really should buy guns, kidnap four people and wait for the counter-terrorists?
I'm too lazy for that.

Or maybe he does not want his now-current data to fall into wrong hands after 128 gigayears?
"hack the registry" :)
basically you have to run this command
%systemroot%\system32\reg.exe add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\autorun.inf" /ve /d "@SYS:DoesNotExist" /f
It tells windows to read a registry key called "HKEY_LOCAL_MACHINE\SOFTWARE\DoesNotExist" instead of autorun.inf file (when such a file exists). Since the key does not exist, windows thinks that the autorun.inf file is empty...

It should be easy if the device ever connects to the internet. Its actual IP address will be logged somewhere or not?
