#anthropic #fable biosecurity classifiers suck. I've been booted out of Fable for: - editing download URL to the latest version of CryoSPARC analysis suite - edited an ansible playbook that installs dozens of R packages most commonly used by life scientists - had "bioteam" name in a playbook

Been telling #AWS #HPC people for a while that old parallelcluster stacks are gonna start breaking soon and have spent weeks upgrading client systems only to discover that AWS pushed the break-date into 2027 thanfully. Blog writeup at bioteam.net/blog/tech/cl...

If you do #HPC on #AWS via #ParallelCluster then check your versions. A ton of old HPC clusters are gonna fall over in June 2026 when AWS deprecates an old python runtime in Lamda. I've done 3 client upgrades this month and expect more to come ...

Claude code is surprisingly good at sanity checking AWS ParallelCluster HPC config files. When paired with the MCP that queries instances.vantage.sh it can validate ec2 server config and even provide summarized cost updates on what each compute node config change will cost.

Timelapse from the volunteer wood bank splitting session. 24 cords cut and split. Goal is to get to 80 cords this year. Lots more trees on the way so clearing the current pile of rounds was a huge milestone.

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. #DGXSpark #AI www.theregister.com/2025/10/14/d...

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

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!

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

Speedrunning regaining my expired #aws certs. Got five in five days, although two were the foundational tier exams. Gonna pause and study hard for the next series. I want Architect Professional, SysOps Professional and the Security Specialty certs next. AWS Professional exams are *hard* though

Annoyed that I let all my #AWS professional, associate and foundational certifications expire out of laziness so I just booked 4 remote proctored exams in 4 days. Gonna clear the foundation/associate ones before taking the Professional exams later.

I do a lot of #HPC clusters running #AWS #Parallelcluster for computational chemistry, specifically integrating it with the www.schrodinger.com small molecule & molecular dynamics tools. Wallclock time to create a new on-demand GPU node & scale it in for a job was 4min 9sec. Fastest yet!

first building we are rehabbing on the 12acre commercial lot. New roof & solar already in. weed growers trashed it, all drywall and insulation was moldy & they covered the beautiful windows. nice to see it opened up! And opening up the windows makes a huge difference #Maine #BethelMaine

I work on the biggest GPU supercomputers on the planet, and none use a parallel file system, full stop. As Jeff says, file-based storage offers nothing uniquely useful to training. Files are for people, and no people are touching data when training at scale.
