the only downside is modern drives have tiny magnets compared to the old ide drives. real old school mfm drives had magnets that could break fingers.

the first thing i had to do working helldesk was find a vendor to dispose of hard drives i think my boss was expecting a shredder, but whichever company came had a little electronic press that would just bend the platter in one spot. works for me. vOv

also re: harddrive magnets, the ones i got out of some old hard drives had convenient holes in the mounting brackets on either side of them so i used some screws to attach them to the side of my workbench and i can hang small to medium size tools from them now, it's real handy

while we're on the subject, is ram disposal still a thing? we try to donate our old towers (which aren't overly powerful but are still miles ahead of the usual stuff they'd get from gov't surplus, i think we're surplussing gen 2/3 i5 boxes now) to local orgs and we're pulling drives and memory; drives i get but memory?

counterpoint: our surplus stuff spends at least a few months in a locker somewhere, powered off i'm like 90% sure there's a pretty short window where which data can be recovered via freezing, iirc you need to dunk the chips while the system is on or very recently powered off

These online coding interview or playground things are great. I got poked by someone today how Skype's new "interview" feature runs any and all code you throw in. including Python's os.system.. is there a way at all to protect yourself from abuse there? or whats the idea

Every one I've looked into has run on spun up then destroyed vm instances with locked down settings in dmzed network areas. You'd need a hypervisor escape to exploit and would still basically be outside the network after that.

Cocoa Crispies posted:isn't the whole freezing ram thing related to a ram behavior that allows what it holds most of the time to influence the state it defaults to? DRAM stores data as charges in tiny capacitors, representing a 1 as a charge and a 0 as no charge or vice-versa; this charge is used to hold a field-effect transistor open or closed to represent the data. in a perfect world the capacitors will hold their charge forever (theoretically the FETs don't draw any current) but in real life they leak over time due to various imperfections in real materials and lose their charge. DRAM periodically "refreshes" the capacitors by writing the stored data back to itself to prevent this loss of charge and thus a loss of data the leakage is great enough that without refresh the data will be lost in a fraction of a second, so the refreshing normally happens many times per second to prevent lost data cooling the DRAM ICs reduces the leakage enough that it will last several seconds without refresh so you can quickly swap the RAM stick into another computer without losing data, so when the second computer begins refreshing the data it will maintain whatever was in it however regardless of cooling the capacitors will still leak enough that within more than a several seconds the data will be lost forever because at that point the charge in capacitors representing a 1 will be indistinguishable from the charge representing a 0 there's no point to shredding RAM edit: no point unless there's a policy that just shreds everything to be safe, but definitely no point to pulling out the ram specifically to shred it alongside the drives and nothing else BattleMaster fucked around with this message at 00:15 on Sep 2, 2017 |
