that would be security through obscurity - which we all know can not be relied on.
The point of a covert channel is obscurity. You could add security on top of it, but putting the message into the data part would defeat the whole purpose of the covert channel. You are trying to find some way to get processes/machines/people to communicate within the confines of the operating system, and without anything/anybody else knowing about it.
An simple example? Say all the normal channels for process communication are blocked. No pipes, no sockets, etc. You can't use files. The only thing you can do is monitor the activity of the other process (ie the 'ps' command). By monitoring, say, memory allocation of the other process, two processes could communicate, sending the data byte by byte. Once a byte is sent, the receiving process could increment its memory to confirm. Then the sender increments its memory to send the next byte, etc.
The point of covert channels is that no matter how secure a system appears to be, it is possible for leaks because of things like this (probably more complex).
They don't have to worry about the movie being too short. If the need some filler just add a scene with Indiana Jones in the bathroom. That should eat up an hour or two.
I guess I was a bit off on the quote... Anyway, here it is:
I'm not being harsh, if you actually listen to the lyrics to the song. "Like a traffic jam when your already late"- that's not ironic it's just a pain in the hole that's what that is. When was the last time you were late for something, got stuck in a traffic jam and said "Look on the irony on this , there's irony for ya. I'll tell ya I was in a fierce ironic traffic jam the other day iIll tell ya. The irony was ninety."
No, there's nothing ironic about being stuck in a traffic jam when your late for something. Unless your a town planner. If you were a town planner and you were on your way to a seminar of town planners at which you were giving a talk on how you solved the problem of traffic congestion in your area, couldn't get to it because you were stuck in a traffic jam, that'd be well ironic, I'm sorry I'm late you'll never guess.
I might have heard that act on Just for Laughs. Another good one was:
"'It's a traffic jam when you're already late'. That's not ironic, that's just bad luck. However, it is ironic if you were, say, a city planner. Even better, you're a city planner and you're late for a meeting about the current traffic problems."
Something like that anyway... I remember laughing my ass off.
Americans wouldn't have had any other choice but to put a man on Mars to save face.
I wonder if it still counts if the man is dead. I'd like to see that as NASA's next project: point a rocket at Mars, strap a corpse on there and let it fly. Think of all the money they'd save. Heck, I would volunteer.
In the middle stands Microsoft, determined to navigate these extremes. In the face of a rapidly maturing business market, Microsoft needs to find a way to persuade consumers to upgrade their PCs.
Sounds to me like they want us to upgrade our house. "Oh yeah, four bedrooms is all you'll ever need."
I think it's pretty pathetic and this kid is pretty pathetic, too. When I was kid before computers, you didn't get to play outside until your homework was done, either. Mom and dad checked the assignments, grades, etc frequently to make sure you weren't fucking up.
It's interesting that you say something like that. I grew up in a big family with just my mom. She really couldn't keep track of all of us, so we had to be responsible for ourselves most of the time. I hardly ever did homework, let alone right after school. When I was young it was sports; later, computers. Grade 12 wasn't as good for me because of it, but I knew it was my own fault, and once college came around, I smartened up.
A couple of my friends, on the other hand, had parents similar (possibly worse) than what you're describing. Absolutely no freedom at all. Want to know what happened to them? They flunked out first year college. One of them actually had their mom call a prof to get out of an incomplete assignment. Another has tried several different programs, showing no responsibility, never studying, and totally wasting money.
Just presenting an argument for a child's freedom.
What if Netwon patented gravity and then decided to take a royality from everyone making use of the idea
Newton would be rich, especially if it was a US patent. Since ~30% of Americans are obese, he could just walk around and make money off of fat people. "I believe you're using something that belongs to me. Pay the royalty please. Thank you. Here, have a candy. My treat."
I don't think I ever mentioned going to school in the US. I go to the University of Alberta in Canada. My University gives us a lot of freedom with course selection, but that's my problem. I'm trying to get a little more rounded education with that freedom. I'm sure your accredited University will help you get a nice job.
Also, just because my study habits don't match yours doesn't mean I'm lazy (even though I probably am). Some guys have to study from 8am until 4pm every day in the library to do well, and that's amazing dedication that I've never really had.
I work hard when there is work to do, but I also have a lot of free time, so I choose to exercise, watch TV, visit friends, and read with most of it. That's my choice. These things help keep me energized and prevent burnout, which has happened when I program too much. Saying I'm not working hard enough is pretty ignorant as you know nothing about me.
But, my engineering friends up here don't have that kind of free time, which was the point of my original post.
Since you had to post anonymously, you may never read this, but I thought I would respond anyway.
No offense, man, but engineers take way more shit than programmers. For the record, I am not an engineer or an engineering student, I am a CS student (aka programmer some of the time).
My former roommate and good friend is an engineering student, and their program is way harder than anything I have to do. I'm not sure if you knew this or not, but in order for a University to teach (accredited) engineering, they have to have a certain (read: tough) curriculum, which is not true for CS at all.
While I'm watching TV he's up to his eyeballs in homework. Engineering not only teaches you the science of things, it teaches you to have an awesome work ethic. I would never call myself an engineer, simply because an engineer goes through a heck of a lot more than me. I have tremendous respect for people who make it through that program.
So what you're saying is that I really should send around all those messages that say, "Keep ICQ FREE! Send this to you entire contact list!". Now if you'll excuse me, I have to apologize to a few people...
It's true, actually. They died pretty quick, though. The whole buffalo jump thing really didn't work up there. They'd chase the buffalo over a cliff, and they would float softly to the ground, then they'd have to chase them all over again. So, they ended up starving to death. Very sad story...
Be sure to watch the animation of the sendmail exploit. Talk about rubbing it in. Not only did they post their discovery, but they made a cartoon about it. That takes some time to make, so they must think they'll be able to use the cartoon again. They're probably right - it's sendmail.
That's a good name change. To be honest, I thought the old one made the software sound kind of wonky. I thought,
"Hmmm... The Film
Gimp. Well, I probably can't use this program unless my monitor is fuzzy or my mouse doesn't have any buttons... Or maybe it has a built-in doodle filter that scribbles all over your work after you save."
Very confusing... This name change is a Good Thing I think...
Slashdot Mirror
The guy gave it a rating of 9.6 'superb'. I guess we can rule out depression...
I regret posting that now...
I just know that guy's first name is iMac...

The television companies estimate they could have lost $900 million in business
Of course, that $900 million loss was if the company existed for the next 30,000 years.
Honestly, their quarterly profits are ~$1.4 billion dollars. I just don't see it...

Finally, a good reason to let my sister play.
There's lots of space over here in Canada... Just change the name and you've got yourself a deal. =)
So the computer lab is filled with hairy little men. What's so great about this? You should see my friends at a LAN party... Woohoo! Hack! =)

I'll take my 12*300,000 = 3,600,000 dollars now, thank you. Not bad for 2 minutes of work. Oh, it's an adjective. Damn.What if Netwon patented gravity and then decided to take a royality from everyone making use of the idea

He's referring to it as 'mere engineering', so I think it is relevant. They deserve just as much (probably more) respect than a lot of jobs.

Oh bs.
Exactly. I was joking. I see that you posted that as anonymous, so you may never read my reply.
Wow, I'm obviously not very gifted... I never read the last line of the article.
