Surround yourself with people that push you to do better. No drama or negativity, just higher goals and positive energy. Simply bring out the best in each other by choosing to always use vi over emacs.

One for the local #mit crowd.

Please share as widely as appropriate, we are looking for undergraduate and graduate students to work with the new Office of Research Computing and Data.

A great opportunity to work closely with our fabulous professional team here @ ORCD! Simultaneously learning all about large-scale, modern #hpc, while also helping to support our campus and community!

Most of you know @micheleclamp is a fabulous artist (I’m biased), but back in 2014 Michele asked me for an novel idea for a painting.

Because I’m a total fool, I said: “Why not paint a koala with a gun, I bet no one has ever done that!”

It’s since become a household meme for just how ridiculous all of my ideas are.

Fast forward to 2023, with zero “prompt engineering”, Michele just sent me this:

“Koala with a gun”

I simply just can’t even! Wow!

Splunk to be acquired by Cisco for $28 billion — pretty good exit for greping a few syslogs…

In other news, systemd is super excited.

2023 sysadmin resume:

“Installed and orchestrated a 1,037,089 node #autoscaling #Linux #hpc cluster for a popular iOS #ai app to autodetect #catsofmastodon on the #kubernetes in an afternoon. Deployed #cloudycloudboop (v0.014), and wrote a novel global #observability pipeline in #ramblesplurt to stream over 5,000PB/minute of #ngnix and #syslog data to a set of fifty billion #distributed #cloud objects.

This may be my most truly cursed #cli ever for graphing #network performance?

This one has everything, a hand rolled artisanal #iperf3, some #json feature extraction, and a spot of #awk for fixing rounding errors, oh and of course, some red hot #gnuplot on #linux #terminal action.

Enjoy! hehe. 😆

./src/iperf3 -c testhost -p 22222 -J | jq '.intervals[].sum.bits_per_second' | awk '{$1=sprintf("%2.2f",$1)}1' | gnuplot -p -e "set term dumb ; plot '< cat -' with lines"

jcuff, 10 months ago to proxmox

Is it finally time to flip over to #proxmox for the home lab, or continue to tough it out with trusty #lxc / #lxd on #ubuntu that’s worked for years?

I fear I’m probably going to end up swearing at a UI, and then find myself back in the terminal but with a new set of weird “pve” commands to configure stuff.

The HA and backup stuff really does look compelling though, and may even beat out my assorted artisanal and handcrafted snapshot.sh and rsync.sh scripts... 🤣
