[GTALUG-Announce] Meeting Tomorrow at 7:30pm with Christopher Browne and Scott Sullivan
<http://gtalug.org/meeting/2015-12/> # Terminal Multiplexers and PXE Boot ## Screen, Tmux, Byobu, the Secret Terminal Brains!!! ### Christopher Browne GNU Screen has been lurking around since the 1980s, as a kind of "tiling window manager atop curses". BSD folk spawned an analogue called tmux in 2009, offering both additions and removals of functionality. Byobu offers a harmonization, and (arguably) better user experience. We'll look at some usages, use cases, and see how frequently Byobu Hollywood crashes. ## Good Bye Boot Media! (or, don't copy that boot floopy) ### Scott Sullivan A tour of how network boot/install can save you ever having to burn a DVDs or USB drive. ## Location George Vari Engineering and Computing Centre 245 Church Street, Room 203 Ryerson University <http://goo.gl/maps/16oJ2> <http://www.openstreetmap.org/way/23447525> ## Schedule * 6:00 pm - Please discuss on the general mailing list (i.e. <talk@gtalug.org>) where you want to go for dinner. * 7:30 pm - Meeting and presentation. * 9:00 pm - After each meeting a group of GTALUGers move to the The Imperial Pub (54 Dundas St East) for refreshments and more socializing. # Code of Conduct We want a productive happy community that can welcome new ideas, improve every process every year, and foster collaboration between individuals with differing needs, interests and skills. We gain strength from diversity, and actively seek participation from those who enhance it. This code of conduct exists to ensure that diverse groups collaborate to mutual advantage and enjoyment. We will challenge prejudice that could jeopardize the participation of any person in the community. The Code of Conduct governs how we behave in public or in private whenever the Linux community will be judged by our actions. We expect it to be honored by everyone who represents the community officially or informally, claims affiliation, or participates directly. It applies to activities online or offline. We invite anybody to participate. Our community is open. Please read more about the GTALUG Code of Conduct here: <http://gtalug.org/about/code-of-conduct/>. If you have any questions, comments, or concerns about the GTALUG Code of Conduct please contact the GTALUG Board @ <board@gtalug.org>. --- GTALUG Announce mailing list announce@gtalug.org http://gtalug.org/mailman/listinfo/announce
From Metro News today:
Two top McGuinty aides charged in gas plants computer probe .... Faist was paid $10,000 for wiping the drives out of the taxpayer-funded Liberal caucus budget, police allege. The party subsequently repaid the sum to the public treasury. .... Ten grand to erase some hard drives? Boot a Linux CD or USBKey. Change to the root directory. rm -rf *. Done. Or maybe it was $50.00 to erase the drives and $9950.00 for 'discretion'. -- Peter Hiscocks Syscomp Electronic Design Limited, Toronto http://www.syscompdesign.com USB Oscilloscope and Waveform Generator 647-839-0325

Also, it the drives won't mount they'll need to have the platters destroyed, no? Still pricey. On Dec 17, 2015 5:18 PM, "David Thornton" <northdot9@gmail.com> wrote:

For less than that you could probably destroy the drives and pay back their depreciated cost. Beats finding out that someone's forensic recovery skills trump your data-deletion-fu. I'm told the Pentagon leans toward taking its busted hard drives to a nearby army base and melting them down with thermite. I've found that a .25" drill bit tends to go dull really fast drilling through old hard drives, but a pneumatic chisel with a pointy bit turns them into unreadable scrap pretty quickly. The project being worth $10k to someone does rather say that someone found that a better bargain than going to jail. -- Anthony de Boer
I have thought about a nail gun and a concrete nail. I have one that was cheap and easy to use It takes a 22cal nail gun cartridge. I have thought that it would be an interesting way to have an emergency quick way to destroy disk drives. Setup a concrete nail in a hardened steel tube with an electric trigger on the cartridge. Alternately I could just use a 5LB hammer but that would be slower and way fewer sparks. It is the method that U.S. aircrew supposedly were expected to use for some surveillance aircraft.

They're a former customer of mine: when a disk goes in US data centres, they cut off the identifying label with a power-saw and return it for credit, then grind the disks themselves to dust. Certain field-use equipment is destroyed by shoving thermite or a WP grenade in the back of the case and running like hell. If I were tasked with cleaning up after something that required disk destruction, I'd order a bunch of new preinstalled-windows disks first, swap them out and then disassemble and grind off the magnetic surfaces with a disk-grinder before discarding the old disks. --dave -- David Collier-Brown, | Always do right.

Years ago, when the SAGE air defense system used drum memory units manufactured by Ferranti, they would be resurfaced periodically by being sent to Toronto - handcuffed to a human guard. The drum would be turned down on a lathe and the shavings collected into a bag by the human guard, and the drum then returned back into service. I guess the bag thing was to ensure that no one could reconstruct the information from the shavings, which seems pretty improbable.

This brings up the question... Why not throw the old hard drive into some old plastic bags, invite some friends over and have a sledge hammer party. This is a good opportunity for any gun freaks out there. I tried writing over an old hard drive using a Perl script. The next evening, I shut it down, and I re-wrote the program in C, and then it worked reasonably fast. I now have a wiped 6GB hard drive sitting in a drawer somewhere. -- Howard Gibson hgibson@eol.ca howard.gibson@teledyneoptech.com jhowardgibson@gmail.com http://home.eol.ca/~hgibson

Those harddisks are pretty difficult to destrop completely. I use to disassemble them, remove the magnets, and sandpaper the surfaces. But, that was before glass plates. Now, I drill 4 holes and tape over the holes so glass debris don't come out. I guess, industrial process-wise, heating/melting them would be the cheapest. -- William

Umm, last I checked a sledge hammer wasn't a gun. Has our new government amended the Act to include them as firearms now or something? Or is this just a Toronto thing? -- Anthony de Boer
