250ms would be a bad ping time for normal phone services, however given the choice between having no service or having to wait half a second for a reply using the emergency service I guess the choice is easy. Furthermore they already use satellite links for live news interviews: you notice the delays, but it's not that bad.
The time to get the signal from you to the satellite is only 125 ms (about 38.5 km). The total for your example is 4 times that: 154 km or 500 ms (+ the internet).
First, comparing Belgian law to Canadian law doesn't make much sense.
That said, on a newsserver they aren't only passing on the data, but also actively storing it (from what I've read it can only be considered caching if it's retained for no more than 48 hours). Also, the ISP's are not responsible for finding out which newsgroups contain illegal content. It's IFPI who will look for illegal content and notify the provider of which groups should be closed.
On the other hand it's a stupid idea to close newsgroups because the problem will just spread over to other newsgroups / services (allthough newsgroups are very popular since only 1 user has to upload content once and lots of users can download it (Belgian ISP users have rather low monthly quota's on broadband services)). It also would be better if they just removed illegal posts because right now they're removing the legal posts along with the illegal ones.
But anyone can request an ISP to remove illegal content from their own servers.
Suppose I'm the man-in-the-middle, you set up an encrypted session to my website (which you believe is your bank's) and I set up an encrypted session to the bank. Now I can interpret your input, send it to the bank, interpret their output and send it back to you. Not sure how that button and image are going to help. You could of course verify that you're talking to a MITM and not to your bank by validating the SSL certificate, but if you did that, why would you need to verify again that you're using the bank's real website by using the verify button?
I can't find any documentation on how to set the timeout (allthough you can disable media sensing if you like). I tried unplugging the network cable from a Windows XP workstation a few times and it drops the connection after 5 seconds. Seems like your method might work after all. Still, you might get some comments from your users because it pops up a warning in the system tray immediately when you pull the cable.
Ethernet can cope with a brief unplug without difficulty.
Ethernet doesn't care, it'll just drop the packets. Udp packets will be lost, tcp will handle it. However, most ethernet cards do link detection: check if there's something connected to the other end of the cable as well. When you unplug the cable, the card will detect it and notify the driver. Windows 2000/XP by default will kill the active connections before a tcp timeout occurs.
What's it going to cost to securely install the equipment? Maybe the guys installing it make some modifications so they can get the data before/after the optical link. If you're sending over disks you could send them in small batches. If you have any reason to believe one of them has been compromised, don't use the data on those disks. You'll have to trust the driver or the guys installing the quantum equipment either way.
After you have received the disks you'll have to protect them so no one retrieves the data afterwards, but you'll have to protect your network/quantum link endpoints as well.
Why not just put your work files onto a RAID drive?
Raid is not backup! Suppose you accidentally delete a file, RAID will delete the copy immediately on both disk. In case the files are copied to another directory you still have that copy ofcourse. But what if something happens to the partition? I've seen cases of partition corruption (fat, ntfs, ext2/3) due to power failure where you'd have to spend a lot of time trying to recover files. Using RAID you'd have corrupted both the original and copy, if you're using two separate disks with separate file systems you'll stand a much better chance.
RAID is good for hardware failures, in other cases you still need backups.
1) That password you give your administrator account on your system can be hacked off in under 5 minutes with the Emergency Boot CD EBCD . So much for encryption.
Reading the linked site, it says that you can *change* any password, not decrypt it. You can do the same thing in unix/linux if you have physical access, I also don't see anything wrong with that. If the data is that important, you should guard the computer as well. In the other case it's handy if for some reason the administrator password is lost that you don't lose the system.
2) Files encrypted in Windows 2000 (the OS I tested then on) were still visible in their directories, despite their contents being encrypted. To me, this wasn't good enough. I wanted the whole filesystem to be encrypted, with plausible deniability that the files that certain files (or even file systems) never even existed.
To add injury to insult, I could easily become administrator with the EBCD and get the encryption key easily to break the encryption anyway.
That's where I think (hope) you're wrong. You can change the admininistrator password, but by doing that you'll render the private keys inaccessible. If you want to reset a users password in windows you get a warning that encrypted files will become unavailable, therefor you should use change password. This suggests that the private keys are encrypted using the user's password. When you change your password, these keys first have to be decrypted and encrypted again using your new password. Resetting the administrator password still doesn't give you access to the files in that case.
To protect from losing your files if you forget the passord you can create an emergency disk. This should allow you to gain access to the system to the system in case the password is forgotten. I assume this disk would contain unencrypted private keys for this purpose (never used it, but it shows up on the password related functions). You also get a warning that you should put it in a safe place.
His daughter will definitly still be alive since she's an elf.
I think you're talking about Liv Tyler, daughter of Steven Tyler of the band Aerosmith. Liv Tyler plays an elf in Lord of TheRings. She also plays in Armageddon as do both Bruce Willis and Steven Tyler, which is probably why you linked her to the wrong father.
I wouldn't know what movie any of Bruce Willis' daughters plays an elf in, unless you mean she really is an elf ofcourse.:)
The problem is that javascript executes incredibly slow on almost any browser. This means that if you write a javascript that requires +- 30 seconds to create the hash, you could probably create the hash using a C program in 0.1 seconds. If you are only using the javascript on one installation, chances are small that anyone would put up the effort to create the C equivalent because in this case it's easier to just wait 30 seconds. On the other hand, if a popular wiki implements just 1 javascript hash function, someone will implement it in C, search google for the copyright string of the wiki and can make a post to a 1000 sites in just a few seconds.
So you could effectively implement it on 1 site, but not use it for widespread adoption since this whole hashcash principle is based on the fact that it should be hard to generate the hash any faster.
Just add some javascript that would hash the message, some part of the URL or page, or a salt and that would be a required part of sending.
Unfortunately this means that each installation would need its own javascript function. Otherwise you just take a look at the wiki package, see what sort of computations it does, write a program to perform the same computation in C, do a google search for the wiki engine and compute 1000 hashes in the same time the javascript has calculated one.
Although Bayesian method(s) are primarily used for fishing out spam, why not use them for general purpose mail-sorting? The databases can be trained and each message checked for user-specific categories: "Family", "BSD", "Support", "Online-Orders",..., and -- of course -- "Spam". Messages, that don't fit into anything will continue to arrive into the main mailbox.
At least you would learn what a ton of amperage at 12V would do to your extremities.
What does the amperage of the power supply have to do with the shock you get in this case?
Considering a typical 100k to 600k Ohm resistance between two hands (dry skin), you would only have a current of 12 / 100k = 0.12mA, which you normally wouldn't feel (needs about 1mA). If your hands were wet, you'd have a resistance of about 1k Ohm, which would give you 12mA that would be noticable, but it wouldn't really hurt you. The total amount of amps your power source is capable of generating doesn't matter much in this case.
At least that's the way I understand I = U / R works.
A few weeks ago there were some news reports about Natasha Demkina, a Russian girl who seems to have x-ray eyesight. Some coverage here and here, or just google for the name.
I don't know how much of this is because my ISP is doing its part to stop spam.
You mean you suspect your ISP of filtering your mail without you knowing it? I cannot imagine you want someone to filter your mail without your explicit permission.
Ok, maybe that was a bad reference as a primary reference. Still, I was only pointing out that there are lots of lengths you can choose from when you're using a cubit. The standard English cubit is 18 inches, but there are lots of references to other lengths as well, not only by aol members.
1234.
According to this page, cubits can range from 12 inch to about 39 inches. It seems like their cubit is more like 20.6 inches.
"Cubits" range from less than 12 inches in the case of Pygmies, to more than 36 inches, in the case of Giants. The cubit of the king of Bashan was estimated to be 39.37 inches. (A Meter-long Cubit!:)
The "1992 World Almanac and Book of Facts" gives a Roman Cubit of 17.5 inches, a Greek Cubit of 18.3 inches, and a so-called "Biblical Cubit" of 21.8 inches.
Collier's Encylopedia (Weights and Measures, pages 394,395) gives an Arabian(black) cubit of 21.3 inches, an Arabian(hashimi) cubit of 25.6 inches, an Assyrian cubit of 21.6 inches, an ancient Egyptian cubit of 20.6 inches, an ancient Israeli cubit of 17.6 inches, an ancient Grecian cubit of 18.3 inches, and an ancient Roman cubit of 17.5 inches; The last two agree with the 1992 World Almanac ones.
Webster's unabridged dictionary gives a Roman cubit of 17.4 inches, and an Egyptian cubit of 20.64 which is about the same as Collier's. And, (of course,) Webster's ENGLISH dictionary for english-speaking people in the U.S.A., gives a modern ENGLISH CUBIT of 18 inches.
Guess they're going for the Egyptian one. Next quarter all they have to do is increase the size of their cubit instead of improve their technology to get a higher "density".

Actually, you would pay $9.99/month * 12 months/year * 70 years = $8,392. Since there's only 12 months in a year and not 52.
($9.99/week * 52 weeks/year * 70 years = $36,363)
