Back in March, we covered the story of Davis Lu, a disgruntled coder who programmed a logic bomb into his employers’ systems. His code was malicious in the extreme, designed as it was to regularly search for his Active Directory entry and fire off a series of crippling commands should it appear he had been fired. His 2019 sacking and subsequent deletion of his AD profile triggered the job, wreaking havoc on servers and causing general mayhem. Whatever satisfaction Lu drew from that must have been fleeting, because he was quickly arrested, brought to trial in federal court, and found guilty of causing intentional damage to protected computer systems.
Lu faced a decade in federal prison for the stunt, but at his sentencing last week, he got four years behind bars followed by three years of supervised release. That’s still a pretty stiff sentence, and depending on where he serves it, things might not go well for him. Uber-geek Chris Boden has some experience in the federal prison system as a result of some cryptocurrency malfeasance; his video on his time in lockup is probably something Mr. Lu should watch while he can. Honestly, we feel bad for him in a way because we’ve been there; we certainly toyed with the logic bomb idea when we were coding for a living, without actually ever doing it. Maybe he thought it would just get treated as a prank, but that was probably never in the cards; as we’re fond of telling our kids, the world just doesn’t have a sense of humor anymore.
Speaking of prison, when was the last time you had to use a floppy drive? Retrocomputer fans excepted, chances are good it’s quite a long time ago, unless you’re an inmate in the New Jersey State Prison, where USB drives are not allowed. Instead, prisoners working on appeals or continuing their education are forced to use 1.44-MB floppies to exchange data with the outside world. The New Jersey prison rules seem a bit anachronistic, since they allow a pretty generous stack of 3.5″ floppies — 20 diskettes — but disallow USB sticks. True, the USB form factor is more easily accommodated in the standard-issue prison wallet, but the materials in a stack of floppies seem like they could easily be fashioned into a shiv or shank.
We’ve said this before, but we’ve got to start hanging around a better class of dumpster. Were we to, we might get as lucky as a Redditor who reports finding a sextet of 1 TB solid-state drives in a bin. The lucky dumpster diver doesn’t say much about where they were found, perhaps wisely so, but other Redditors in the thread were quick to point out that they were probably in the trash for a reason, and that they might be a little clapped out if they came from a server array. Still, 6TB of free storage isn’t something one lightly passes up on, and even if the drives have seen better days, they’ll probably be adequate for non-critical applications. For our part, we’d love to find one of those mythical dumpsters that seem to spawn things like Selectric typewriters, supercontinuum lasers, or even all the makings of a semiconductor fab.
And finally, Brian Potter over at Construction Physics posted an excellent essay this week on the early history of the Ford Model T, the automobile that gave birth to America’s car culture, for better or for worse. Everyone seems to know the story of how Henry Ford invented the assembly line and drove the cost of a car down to around $400, making motoring accessible to the masses. And while that’s kind of true — Ford is said to have picked up the idea of moving the workpiece rather than the workers from slaughterhouses — it leaves out a lot of interesting details, which Brian picks up on. We were particularly struck by how late in the game Ford introduced assembly lines to Model T production; it wasn’t until 1913, and then only as a small-scale line to assemble the flywheel magnetos used in the ignition system. Once that line proved itself by reducing magneto assembly times by a factor of four, Ford’s process engineers began rolling out the concept across the plant. There are a ton of other tidbits in the article — enjoy!
Not only did his code delete data (namely the user profiles of his coworker), seemingly it also tried to prevent people from stopping the process and recovering. I don’t think this ever fell under something that would tickle anyone’s sense of humor.
Hard disks and SSD’s with decent capacity are aplenty if you know where to look.
I have access to too many decomissioned high idle hours, low read/write 4TB enterprise HDD’s that test just fine, and I just finished testing about 16 or so ‘scrapped’ 800Gb Micron SSD’s.
The real holy grail is finding multi terabyte SSD’s or spinning rust in the double digit terabyte range, they are currently a bit hard to come by…
I use the vendors disk utilities to get an idea of health and SMART status, and also use something like Disk Genius etc to do a proper scan of the disk to ensure no bad blocks.
