My word, with all the laser pointers in use, how many people do you know that have been disabled by such a device?
from http://www.drgreene.com/21_607.html:
A laser (light amplification by stimulated emission of radiation) pointer is a device that transforms ordinary light into an extremely intense and nearly non-divergent beam of light of a single color, with the light waves all in synch. Depending on the intensity of the light, lasers can mobilize immense heat and power when focused at a short range. They are being used for exciting new surgical techniques.
Lasers are classified according to the maximal power output. Class 1 lasers (500 mW) are dangerous military, medical, or industrial lasers.
Laser pointers are class 3A (1 to 5 mW) and are required to carry a warning cautioning users to avoid shining a laser pointer beam into anyone's eye. But class 3A lasers are less dangerous than most people think. The most well-supported risk estimate suggests that the retina can theoretically be damaged if someone were to stare into the beam for 10 seconds (Ophthalmology 1997; 104:1213).
This is nearly impossible to achieve. In this situation, 10 seconds is nearly an eternity. The pupil, blink, and gaze-averting reflexes stop significant exposures in less than 0.25 seconds. Even in the office of an eye surgeon, with a chin rest, a target, and a machine to aim the beam steadily, it is difficult to keep a beam on a single spot for more than a few tenths of a second. So, a laser pointer in mischievous hands carries no real risk for immediate or delayed retinal damage.
Lasers can, however, dazzle the eyes. Both pain and dazzle spot images are common results of looking at a laser beam. This has given rise to panic in many individuals. Although laser pointers have never been found to do damage, they have produced hysterical blindness--people who can't see because they are convinced they can't (The Lancet 1998; 351:1291).
On a slightly off-topic note, could you imagine where we would be if u$oft *didn't* use an already established, good TCP/IP stack, or didn't use TCP/IP at all?
eep.

Why GNU su does not support the wheel group (by Richard Stallman)
Sometimes a few of the users try to hold total power over
all the rest. For example, in 1984, a few users at the
MIT AI lab decided to seize power by changing the operator
password on the Twenex system and keeping it secret from
everyone else. (I was able to thwart this coup and give
power back to the users by patching the kernel, but I
wouldn't know how to do that in Unix.)
However, occasionally the rulers do tell someone. Under
the usual su mechanism, once someone learns the root pass
word who sympathizes with the ordinary users, he can tell
the rest. The "wheel group" feature would make this
impossible, and thus cement the power of the rulers.
I'm on the side of the masses, not that of the rulers. If
you are used to supporting the bosses and sysadmins in
whatever they do, you might find this idea strange at
first.
Uhm, You're obvously security unclued... this is only exploitable by people with access to your machine. a 'worm' would not work.
Don't get mad at the security community for your lack of understanding on how to admin a machine. Everyone gets hacked sometime, it's your responsability to make sure it's not on your watch.
"Man, I was bummed out by comdex this year. Where was the cool Linux business expo that there was last year? Granted, Linux International was there, and I got my picture taken with John Maddog, but I was disapointed."
Hint: What happened to all those "Linux Businesses" that "existed" last year?
Yes and no. The problem with this is that the "body" in this case would be Windows NT. The "asprin" (patch) would have to be made by Microsoft, or another party privy to the broken mass of crap that caused the problem to begin with. For example, in a number of cases with Open Source projects, when an exploit is made public, it usually comes with a code snippit showing where the problem is, and frequently a patch.
Your "self-described security community" can't patch Microsoft mistakes, even if "it's high time that computer users insisted that the security community live up to its obligation to protect them."
I like how when Mr.Culp wants a community he doesn't support (self-described) to take responsability for his companies follies (live up to its obligation)
Could someone plz upload 1-800-flowers to Napster for me? Will trade for almost any of the "Help, I am stuck in a freezer, save me!" songs from Short Circuit 2. (except "Broadway", I hate that friggin song.)

Sure! I saw some fat kid do it on video, and he gave it to his future sex life, as a gift.
Just to be clear... A single jail is limited to a single IP. So you need one unique IP for each Jail on a machine.
Doesn't Linux 2.6.* have similar and better functionality now that SecureSomething patch has been merged into it?
Wow, what an interesting comment! "Linux 2.?.? has a whoosit something whatcha hoo hoo I heard someone maybe talk about? It's better than BSD, tho!"
Helllllllooooo?!? You put it above your *bed*.
On a slightly off-topic note, could you imagine where we would be if u$oft *didn't* use an already established, good TCP/IP stack, or didn't use TCP/IP at all? eep.
Also, you can get the bluetooth adaptor from expansys and get your TCP/IP on (OSX Win32)
strange, the OSX solution is free. hmm.
It's Linux that cannot handle the load.

From FreeBSD's port archive, this will fix 3.0.2:

I don't like the GPL, but I like lawyers who d this kind of business to be more annoying than the GPL.
Joe Chemo would be proud. This is exactly what antitrust laws are supposed to prevent.
