There is no security reason served by these restrictions. It also blocks SSH and FTP. Last I heard, schools were places to learn about new things, like how to setup SSH at home and access it from school.
XSS is *VERY* easy to prevent. Much more so than SQL injection.

You've obviously never worked in any private organization bigger than a little league team. If you had, you'd know that Apple, and all enterprises like it, have thousands of discretion-free low-level dweebs like the one just described. Ascribing some deeper purpose to such people is silly.
Apple sends threatening letters to everybody because it is cheaper for them to do so. They run the risk of bad PR and cause a negative externality on everybody else. Apple, and all corporations who act similarly, deserve the blame ascribed to them.
From Act 3: (1) Persons taking no active part in the hostilities, including members of armed forces who have laid down their arms and those placed hors de combat by sickness, wounds, detention, or any other cause, shall in all circumstances be treated humanely, without any adverse distinction founded on race, colour, religion or faith, sex, birth or wealth, or any other similar criteria.
To this end the following acts are and shall remain prohibited at any time and in any place whatsoever with respect to the above-mentioned persons:
(a) violence to life and person, in particular murder of all kinds, mutilation, cruel treatment and torture;
(b) taking of hostages;
(c) outrages upon personal dignity, in particular humiliating and degrading treatment;
(d) the passing of sentences and the carrying out of executions without previous judgment pronounced by a regularly constituted court, affording all the judicial guarantees which are recognized as indispensable by civilized peoples.
Sysadmins are going to make your job hard (wouldn't you?). Nobody likes knowing how to fix a problem but having to go through somebody else. Why are you needed? This smells like a manager came up with the idea without understanding how sysadmins operate.
If you're looking to hire good Computer Science people, make all your emails plaintext. For more fancy formatting, use HTML forms and PDF. Many companies do not realize that UNIX sysadmin applications should not be Word attachments.
RTFA. They copy what the bittorrent client (running on their computer from their IP address) reports to the tracker. Then all they do is send a falsified version. The logs would show both spoofing and legitimate clients accessing the same url.
What one could do is search the logs for jumps in upload rate. For example, a user might be going 10 kb/s upload for a long time (while getting the file). Then all of a sudden it went to 10 Gb/s and nobody joined the torrent. Further if the sum of all downloads during that period is less than the sum of all uploads then somebody is probably cheating.
I was cleaning a computer lab today. Under a desk were piles of CS final exams and progress reports from 1992-5. Not that I could change the grade, but it's a bit scary to think that's where those things end up. One of them belonged to a current staff member. She was slightly scared when I gave it to her.
We're not talking about people running open relays. The problem is largely windows users who got trojaned and are now sending spam. These trojans usually connect directly to destination mail servers so stopping open relays won't fix it.
Interestingly enough, the only thing that they save in a disposable camera is the AA batteries. Not true or no longer true. Kodak pays 3 cents for the camera (even if not theirs) and 5 cents for camera and AA or AAA. Every two weeks or so somebody comes to the lab I worked at. She counts the cameras and batteries, lining them up nicely, and hauls off two big bins for recycling.
Note thate [sic] compared to fvwm2 [which I have only used in cygwin] icewm supports multiple desktops, has a clock, start menu and tray. icewm also has nice window decorations.. Uh. . . have you ever tried configuring fvwm2? For some example config files you might want fvwm themes which has many themes with their own window decorations, "start" menues--taskbar like to button bar, a tray. Not to mention they all have virtual desktops (FvwmPager). Total memory usage by fvwm: 4.7 MB
Would that percentage happen to be 100/2^32? Or better since RSA is modulo m: 100/m where m is in the range of 2^1024. There is a really really small chance of getting it right. Then follow the geometric distribution and your average number of tries is 2^1024. . . somehow I think the bank would notice.
But you assume one mass in the universe. With multiple masses, the gravational fields cancel at points, so gravity can be equal to zero. Consider a simple two mass system of m and M separated by r. Solve for the distance s from m where gravity is 0. Gm/s^2=GM/(r-s)^2 m/s^2=M/(r-s)^2 m(r-s)^2=M s^2 m(r^2-2rs+s^2)=Ms^2 0=(M-m)s^2+2mrs-ms^2 So lving the quadratic for s, we have s=-mr/(M-m)+sqrt((2mr)^2-4(M-m))/(M-m) Now granted this is temporary since the masses will likely be orbiting. It also assumes two masses in the universe but this calculation can be repeated for as many masses as you want and it will usually produce an answer (in the case of far away other masses, a slight movement from this soltion). Go read a high school physics book, will you? Pay attention to addition of forces.

It is single master, many slave replication only.
What happens if there is a security hole in these? Do they ship new CDs to everybody? Of course, one can get any hacker out by rebooting but what happens if somebody runs a script that roots it every time it shows up on the network? Or what about computer labs where one just roots every computer?
Um. . . User Mode Linux is running Linux on top of Linux. Running a game in user mode linux does not make it go faster. The host still has a regular kernel and all the daemons.

True. Some of us run ARM.
Caltech with its 939 undergraduates never has a chance at getting on the list.
Um sending people an error page is NOT surviving a slashdotting.

If the government has a harder time keeping track of people, maybe it will be less ambitious. Never mind.
Just keep a counter of the number of time you receive it. That's compression since you can still recall each one.
