The sequence to safely reboot a locked Linux box is:
Alt-SysRq-R --- Turns off keyboard raw mode (sets to XLATE)
Alt-SysRq-S --- Syncs the filesystems
Alt-SysRq-E --- SIGTERM to all processes except init
Alt-SysRq-I --- SIGKILL to all processes except init
Alt-SysRq-U --- Remount the filesystems readonly
Alt-SysRq-B --- Reboot (like pressing ctrl-alt-delete in DOS)
An easy-to-remember saying is "Raising Skinny Elephants Is Utterly Boring"... I found that in one of my Linux books (although I cant remember wich one, so I cant give proper credit... sorry).
The sequence should work even when the system appears to be locked hard. Often, all that is required is Alt-SysRq-I, wich will kill the runaway process(es) that has caused the system to crash.
All that the record industry had on the alleged thief was an
eight-digit Internet protocol address, 141.158.104.94.
I see four numbers made up of eleven digets, but if they're only worried about the first eight digits, then whoever the RIAA is after doesn't have anything to worry about;)
Same thing goes for backing up the bootloader when installing a new os that isnt multi-os friendly (such as windows). Why use an entire CD-RW for grub, when a floppy has R/W support both in the BIOS, as well as EVERY OS that the PC will run? (well, maybe theres something out there that I dont know about)
Sure, floppys arent good for much, but every computer needs to be able to boot in a crisis, and being put at a DOS prompt with FDISK is a pretty good way to boot.:)
No. I have *.exe (among other things) blocked at the firewall. I have never figured out why anyone would name a webpage with a.exe extension. Especially now that viruses/worms are so rampant, and there are so many holes in the popular browers. Its too bad, too, because I would like to have been able to read the article
Actually, a similar concept is already entering test stages: Retinal Implants (Google search). It uses a microchip to send signals to the nerves in the retina. One could be modified to display an overlay of a signal coming from your PDA. It would be quite an interesting feat. Unfortunately, it looks like this will not be availible even to the rich for several years.
I agree that something like that would be cool not only for PDAs, but for computers, televisions, and anything else that needs to display something for you. The biggest benifit I could see would be for wearable computers. You wouldnt need to have a bulky screen attached to your glasses.
I use Mandrake 9.0 on two boxes as well. After reading this article I felt guilty for D/Ling the ISOs, so I joined the Club at the $5/mo level. The only thing that made me fell ok about it before was puchacing the 8.0powerpack edition.
Thier default install is a bit bloated, but that is easially remidied by using rpmdrake, or just not selecting the packages you dont need durring the install. Mandrake has the best balance of gui features for newbies and poweruser control of any distro that I have tried. br
It will be a sad day if they are not able to recover from their past mistakes.
"Things to keep in mind:
1) If you participate in illegal file-sharing networks, your
computer now belongs to the RIAA.
2) Your BlackIce Defender(tm) firewall will not help you.
3) Snort, RealSecure, Dragon, NFR, and all that other crap
cannot detect this attack, or this type of attack.
4) Don't fuck with the RIAA again, scriptkids.
5) We have our own private version of this hydra actively
infecting p2p users, and building one giant ddosnet."
So (supposidly) even someone who looked at every packet entering/leaving their network would not see this traffic... Not that I believe them (I'm going to setup a Snort box to check, though.)
Actually, if you want to use that analogy, then its more like this: The landlord told Joe's Gas Station that yes, they could continue to lease the property, and then recieved payment for the next year (as well as the signed lease).
The landlord then turned around, forgot about Joe's Gas Station (who has already signed the lease and payed the ammount due) and signed another lease with Bob's Gas Station.
When Joe's Gas Station asked what the hell was going on when Bob was there the next day, the landlord shruged and said, "Too bad for you, I forgot about your lease and gave it to Bob. You'll just have to find another gas station for lease."
The problem is that the poster seems to have to be on-call durring the night, so simply turning off the phone wont work, as he would not have a job to go back to in the morning.
I'm not sure what he wants us to do about it; the only thing he could really do is request that someone else be put on-call so he can get some sleep 3-4 out of the 7 nights a week.
Someting to do, on the otherhand, is turn the volume on the laptop down, and not put it *right* next to his head. Theres no reason that he needs to be notified of email in the middle of the night, anyway. Perhaps move everything with a fan to the otherside of the room just for good measure.
Just my $.02
Whatever happened to the "BOSS" key? Back in the old (DOOM/Wolfenstein) days, F10 dumped one to the prompt w/o asking in case the boss comes by. A quick CLS and all the evidence is gone. Even if you Alt-Tab, theres still the taskbar icon. Also, on many games, alt-tabing causes the texturemaps to get messed up, so when you reenter the game, everything looks funny.
Better yet, howabout switchblade [ken | male doll] (i dont remember exactally). or Bag O' Glass. That was a favorite in my house:
Mr Mainway: Here. Try this one. We call it Bag O' Glass. Kids love it
Reporter: *blink* Its glass. its SHARP.
Mainway: But its glass. kids love it. its shiny. Ya' set it on the table - eh - Bag O' Glass! See. Its shiny ... etc...
http://www.thinkgeek.com/cubegoodies/posters/... There's only one Linux poster, but it seems kinda neat.
Check out the other posters too, cause they dont ALL have to be about Linux/BSD.
These recommendations do not cover disasters such as 767s flying into the building and killing all the sysops. Earthquakes dropping the building on the same. Etc. The people are the most important part of any company and, if too many of them are lost at once, the company probably is lost too.
Perhaps if the disaster recovery plan included dummy instructions for getting basic services back online. A manual that was as easy to follow as "..insert the tape labeled 'usrbin20021119-6' and type 'tar -xzfv/dev/st0'. Now change directories to/home and insert the tape labeled 'home20021119-3' and type 'tar -xzfv/dev/st0'..."
With a system like that, the entire IT department could be killed and as long as someone knew where the disaster plan was, the site could be recovered.
"We don't like Apple's attitude. Therefore, we're going to hose their customers... not by saying that Apple is wrong, but by saying that the Mac platform is poorly supported by the software industry! Heh, that'll learn them".
The funny thing is, this whole thing makes me want to run out and buy a Mac to support Apple. If Apple is not going to "support" DRM by forcing it on thier customers, then I'm just going to have to join that "unsupported" customer base.
How big a file do you edit on your palm? A screen full? A page? What if someone is working on a 15 page document, spends 45 minutes changing it around, then decides to scrap most of the changes? Do they have to click 45 minutes worth of "Undo"?
The current solution is to open the saved version and copy/paste... Without manual saves, it would be almost impossible to do such a task.
I would suggest that your current manager talk to the "higher-ups" and explain what you are doing RIGHT NOW. That way, confusion can be avoided later. After that is done, I would have a contract drawn up by lawyers (on both sides) so that you each understand exactally what is happening and exactally what is expected.
Cable companies often have dialup access, as well. AOL has Dialup, AT&T has Dialup... Cant say about the others, but I bet they have dialup too.
If you lump Broadband and Dialup subscribers of those companies into the category "provided by a cable company" you end up with a large portion of the US.
When AT&T took over @Home, our Downstream got capped at 1.5MBits (before we could get 5-6 sustained and 8 peak) and uped our bill $7 a month because we own our own modem.
Too bad they're the only ISP who could get service installed in under a month and a half....
Seems very similar to /. math, or perhaps "White House math" ... 15*32,000=32,000

No, we're not quite there yet. But we're somewhere on the curve e^x, so it won't take much longer.

Future warning:
"Are you sure you want to view the contents of c:\documents and settings\ryan\my documents? Editing a file could cause the file to be changed."
I can reboot while in the BIOS by pressing Ctrl-Alt-Del, therefore it also must be based on MS-DOS.

Perhaps HP has purchased Slashdot, and is planning on purchasing Red Hat as well...
Whos going to refute it? They did merge with Compaq, afterall...
