Been volunteering at a new local firewood bank in Bethel, ME that is just gettting off the ground. Drove our tractor there 6mi over main roads which was a first.
This is a Timelapse of the “rounds crew” who saw full length trees into rounds. The wood splitter teams than process the rounds.

This was a fun review. I don't think folks realize how big a deal the DGX Spark is. A year ago an #Nvidia #workstation with 128GB+ of VRAM cost tens of thousands of dollars. Is it better than AMD's Strix Halo? Now that's the real question.

DGX Spark Nvidia's desktop supercomputer: first look
hands on: This relatively-affordable AI workstation isn’t about going fast; it’s about doing everything well enough

Used the US long holiday weekend to run #AWS #ParallelCluster build-pipeline and cluster deploy through a logging squid HTTP proxy to document internet destinations used -- this helps set firewall rules for orgs that block egress by default in research VPCs
ParallelCluster, External Destinations & Firewall Rules - BioTeam
When Internet egress is blocked by default inside your cloud environment, what external sites and destinations need to be allowed for AWS Parallelcluster?

any #AWS #HPC folks familiar with the managed PCS service who can confirm that when using AWS PCS you can't configure Slurm to be aware of software licenses?
Adding license at CLI does not persist & API guide seems to confirm that "SlurmCustomSetting" does not support the "License" param ...

some cryoEM validation runs via cryosparc.com software integrated with #AWS parallelcluster HPC and using an FSX/Lustre parallel filesystem built from S3 input cryodata bucket via Lustre/S3 data repository associations. Can't do that on-prem!

The maverick hybrid truck was just to be for high MPG errand running and dump runs …. But I needed a rock bucket for the tractor and saw a sweet hydraulic dump trailer on dealer lot….
guess I tow stuff now. Swore I’d never own anything that could tow, hah!

@techaro.lol users of spack just became collateral damage in the anti AI-scraping wars. All I'm trying to do is use spack.io to compile relion.readthedocs.io/en/release-5... for CryoEM analysis on an HPC cluster.
I know this is not your fault of course but wanted to point out an edge case

western Maine project continues. When this was a gravel pit they piled the good topsoil in one spot but it got overgrown w/ sumac & weeds.
Eventually we are gonna rent a big ass screening machine to separate out good dirt from rocks/trash and use the lovely soil for meadow planting & remediation.

No longer just a “tractor guy” as the Chinese mini excavator arrived. Midlife crisis takes many forms, heh.
This is the ECE CTX8012 Pro model. 1.5 ton diesel w/ all the features I wanted like swing boom, aux hydraulics, two speed tracking, expanding tracks & quick hitch
