Lisp code was live-debugged and fixed with REPL on a spacecraft 100 million miles away
“An even more impressive instance of remote debugging occurred on NASA's 1998 Deep Space 1 mission. A half year after the space craft launched, a bit of Lisp code was going to control the spacecraft for two days while conducting a sequence of experiments. Unfortunately, a subtle race condition in the code had escaped detection during ground testing and was already in space. When the bug manifested in the wild--100 million miles away from Earth--the team was able to diagnose and fix the running code, allowing the experiments to complete. One of the programmers described it as follows:
Debugging a program running on a $100M piece of hardware that is 100 million miles away is an interesting experience. Having a read-eval-print loop running on the spacecraft proved invaluable in finding and fixing the problem.”

Got pulled out of bed at 6 am again this morning, our VMs were acting up again. Not booting, running extremely slow, high disk usage, etc.
This was the 6 time in as many weeks this happened. And always the marching orders were the same. Find the bug, smash the bug, get it working with the least effort. I've dumped hundreds of hours maintaining this broken shitheap of a system, putting off other duties to keep mission critical stations running.
The culprits? Scummy consultants, Windows 10 1709, and Citrix Studio.
Xen Server performed well enough, likely due to its open source origins and Centos architecture.
Whelp. DasSeahawks was good and pissed. Nothing like getting rousted out of bed after a few scant hours rest for patching the same broken system.
DasSeahawks lost his temper. Things went flying. Exorcists were dispatched and promptly eaten.
Enough. No consultants, no analysts, and no experts touched it. No phone calls, no manuals, not even a google search. Just a very pissed admin and his minion declaring blitzkrieg.
We made our game plan, moved the users out, smoked our cigs, chugged monster, and queued a gnu-metal playlist on spotify.
Then we took a wrecking ball to the whole setup. User docs were saved, all else was rm -r * && shred && summon -u Poseidon -beast Land_Cracken.
Started at 3pm and finished just after midnight. Rebuilt all the vms with RDP, murdered citrix studio (and their bullshit licenses), completely blocked Windows 10 updates after 1607, and load balanced the network.
So what do we get when all the experts are fired? Stabbed lightning. VMs boot in less than 10 seconds, apps open instantly, and server resources are half their previous usage state. My VMs are now the fastest stations in our complex, as they should be.
Next to do: install our mxgpu, script up snapshots and heartbeat, destroy Windows ads/telemetry, and setup PDQ. damn its good to be good!
What i learned --> never allow testing to go to production, consultants will fuck up your shit for a buck, and vendors are half as reliable over consultants. Windows works great without Microsoft, thin clients are overpriced, and getting pissed gets things done.
This my friends, is why admins are assholes.4 -
pms always tell the higher ups that I"don't have passion". I don't know how to show passion for their photoshop mock ups, one line requirements with no definition of done, their talking for hours about "leveraging" and name dropping about the top brass they are schmoozing with. I just ask if we are going to show our MVP to real users and she morphs to the bride of chuckie. I say we ought to pair program and she says it cost double to make a feature. Testing and code reviews are taking too much time but they hover over your shoulder while you try to fix a "mission critical bug" that occurs because they wanted us to skip practices that could have prevented the bug. Woo I feel better now!2
