Introduction I use Claude Code for substantial one-off analysis, and its output is frequently a single self-contained HTML file. Examples include a flight-log dashboard, an interactive trainer derived from an audiobook transcript (described in Building Interactive Trainers From My Audiobook Library), a pedigree chart, and a client map. Each began either as a Live Artifact or as a file in /tmp that I opened with file://, inspected once, and subsequently lost. ...

Politics Dashboard: A Self-Hosted, AI-Summarized News & X Feed Reader I built and open-sourced a self-hosted news dashboard that aggregates political news from RSS or FreshRSS, summarizes individual articles with a configurable large language model (LLM), generates a 24-hour thematic digest, and presents X posts with per-account summaries through a self-hosted Nitter instance. The repository is github.com/RobertDWhite/politics-dashboard; it is MIT-licensed, and multi-architecture images are available at ghcr.io/robertdwhite/politics-{api,ui}. The production image is the same image GitHub Actions builds from main. ...

Weather Dashboard: A Self-Hosted, NWS-Grade Weather Operations Console Bottom line up front. I built and now open-sourced a self-hosted weather operations dashboard built around the US National Weather Service api.weather.gov and a stack of other free public sources (NOAA SPC, AviationWeather Center, NDBC, USGS, RainViewer, IEM). For fun, I also pull in APRS stations from my SDR rig. It renders active alerts with VTEC parsing and polygon overlays, NEXRAD and MRMS radar with time-machine playback, severe-weather products from SPC including ProbSevere v3 and GLM lightning, aviation METAR/TAF/AIRMET/SIGMET, marine buoys and tides, USGS earthquakes, AirNow AQI, and a 7-day NWS forecast. It speaks CAP 1.2 to other systems, fans out severe alerts to Slack/Discord/generic webhooks, and supports VAPID web push for the browser. Repository: github.com/RobertDWhite/weather-dashboard. License: MIT. Multi-arch images at ghcr.io/robertdwhite/weather-dashboard-{api,ui}. The image I run in production is the same image GitHub Actions builds from main. ...

This post was originally published at w3rdw.radio, the ham radio blog of Robert White (W3RDW). It is cross-posted here for the WhiteMatter Tech audience. Always-On SDR: Building a Multi-Band Radio Intelligence Platform on Kubernetes I have been quietly building something i am pretty excited about. The idea started simple enough: i wanted a permanent, always-on radio monitor for 2m. It grew into something considerably larger. Today the stack covers 2m, 70cm, and the full HF spectrum from 3–28 MHz simultaneously: recording, decoding, transcribing, and tagging everything it hears, around the clock, with no manual intervention. ...

Setting Up an ADS‑B Flight Tracker with a Cheap Antenna on Kubernetes (RKE2 and ArgoCD) This is the Kubernetes version of my earlier Docker‑based ADS‑B guide. In this setup, everything is defined in YAML and deployed via ArgoCD, and changes are tracked in Git and synced automatically to the cluster. Access is handled through an NGINX Ingress with TLS from cert‑manager, which is how I publish the ADS‑B UI at adsb.w3rdw.radio. If you’re comfortable editing YAML and committing to Git, you’ll feel right at home. ...
