Jail is a term taken from BSD. In BSD, jail and chroot are two different things, althrough very similar. There exist two syscalls - jail() and chroot().
What's the difference? Chroot is ordinary chroot, the same as in linux. You do chroot/something bin, and/something becomes root direcorty (/) of run program. This program can't open for example/etc/passwd, because _real_/etc doesn't exist in it's/. Chrooted program's/etc is in fact/something/etc. But if you goot root priviledges you can easily break chroot. Just make a special file named 'hda1' beeing a device node (like those in/dev) inside chroot, mount it, and... voila! You have access to whole disk. Chroot is broken. Of course, you must have access for making file, but must chroot have.
Jail is slightly different. It not only hold process in some directory. It's also *restrict* certain *syscalls*. So you can't mount anything, change network settings and some more. Jail is more restrictive and probably you can't break it even if you have root access in jail.
Jail, because of blocking syscalls, must have some help from kernel. Right now, there is a jail() in FreeBSD and probably NetBSD. OpenBSD don't have it - Theo says it's too complicated to be secure. Also Linux don't have jail().
If you want more information, browse FreeBSD man pages, avaiable online.
We have seen how to carry data in one's body. Remember William Gibson's "Johny Mnemonic"? Now we have transmission method, we only have to develop storage.
I hope that KDE won't do stupid things like before in case of esound - they invented arts over it, making KDE incompatibile with de-facto standard. They should've used esound.
Now they could base their shared desktop on IDEAS of VNC, but make it non-compatible:-/
What a bullshit. PPTP service listens on socket bind do tcp/ip port. That's the network 'service'.
I/O port is a way to communicate with hardware, it's like place in computer memory (RAM) when you can write or read bytes and words of information to control computer hardware.
I/O port and network port are two different things!!
Yes, I know. But for many followers of Richard Stallman, possibility of someone using your code in closed source project is an attack on freedom of code. I believe that some linking (during compilation) issues are also important - restrictions in GPL are alleged to keep code free, as in speech. (I'm not a GPL zealot. I'm just aware of GNU Public License intentions.)
It is useful for all those people, for whom BSD license is not enough free. I think that TLS (the new name for SSL, BTW) library is mandatory for GNU/Operating System. And because of GNU it has to be GPLed - now it means reimplemented from scratch. I also fear, that it will be binary incompatible with OpenSSL - if so, it wouldn't gain popularity. It should be drop-in replacement.
But we will see - right now you can test it or go and help developing this crypto library.
In my case it's significantly cheaper to pay $30/month for unmetered cable internet access,
For me it's 35$/month for unlimited 115,2 kbit connection:-/.
But it's real 115,2 kbit - my MRTGs.
Other option is (where I use Internet now, during academic year) 15$/month for 128kbit link, with in reality is 2mbit link shared with 80 other persons:-((.
Both of them have hardly outside-poland connectivity. Yep, I live in Poland, in Internet third world.
Good quality 512kbit link starts at 250$/month. Not whole Europe is ahead US in broadband access.
Q: Can Linux, FreeBSD or another open source OS run on "Palladium" hardware?
A: Virtually anything that runs on a Windows-based machine...
Since when OPERATING SYSTEMS run on Windows? They are completly independent of software platform, all they need is hardware. Only hardware windows I have are those glass things for looking sttreet outside. But they don't run any OS in other hand;)

Why not give

cdrecord already supports this technology - browse documentation and search for discopts=, imagefile=. Be sure to prepare 3000x40 image first :)
