Latest writing and notes

Title Date
ezpz from anywhere: remote submission via the ALCF IRI API Submit, monitor, extend, and cancel HPC jobs from anywhere — no SSH session required. A tour of the new ezpz IRI integration: IRI-first auto fallback, rich status tables, and live resource and incident views, all backed by the ALCF IRI API.
A Small Service Mesh for My Macs and Supercomputers How I run local dashboards, separate personal and agent knowledge vaults, shared agent memory, email, terminal history, model gateways, and persistent agent sessions across two Macs and ALCF systems -- with one health checker for the whole stack.
Working From Anywhere: Persistent Access to Compute and Context A portable working setup that follows me across networks: attaching to always-on agent sessions on my home Mac and on ALCF/CELS machines with herdr, keeping a single cross-agent memory store reachable from every client, staying model-flexible across Claude, GPT, and ALCF-hosted open models, and what happens when a restrictive network breaks the transport underneath all of it.
croon: Synced Lyrics in the Terminal, for Whatever Is Playing Detecting the currently playing song system-wide on macOS, fetching time-synchronized lyrics from LRCLIB, and auto-scrolling them in the terminal — with a four-backend fallback chain because there is no one way to ask macOS what is playing.
globusfs: an fsspec Filesystem for Globus Collections Building an fsspec backend for Globus so pyarrow, pandas, and dask can read a collection the way they read s3:// — and the HTTPS-server quirks that made it harder than it should have been, including a 404 that means two different things.
