In my personal life I use a Framework laptop (love the idea of upgradable) with a 12th gen Intel i7-1260 and 64gb RAM.
My desktop is Ryzen 9 with an RTX 4090 for model inference (and it also runs my 4 monitors).
My non-work cluster is a mix of ARM and x86 machines (from Raspberry Pi to Jetson AGX).
The upstream on my home network are Sonic (local fiber ISP), Monkey Brains (local wireless ISP), and a small capped T-Mobile backup (with a Netgear M5).
For model training I've used LambdaLabs w/ A100s.
Our 3D printer is a VORON 2.4.
Communication
My happiness on a daily basis is probably index to my % of time spent in Emacs and outside vs in Gmail/Meet.

I'm Holden Karau, I work on open source big data tools (mostly Apache Spark) for my day job.
At my day job I mostly use a ThinkPad w/32gb RAM along with an EC2 instance for compiling multiple versions of Spark at the same time.
