⭐ FeaturedTL;DR I built the brain of a two floor, 16 spot parking garage on an FPGA (a chip you can rewire with code). It checks for payment or a permit, decides if the gate opens, and points every driver to the closest open spot on the right floor. When I rewatched the demo, I also caught a bug that would cost a real garage money. The fix is one line. Finding it is the actual skill.
DevOpsTL;DR The OAOS backend inherited a manual JWT-minting auth system wired to a database that no longer existed. We ripped it out and rebuilt it as a Keycloak + OpenFGA gateway; proper authentication, fine-grained authorization, compliance-ready from the ground up. This post covers the architecture decisions, the refactor, and the debugging gauntlet that stood between us and a green system.
DevOpsTL;DR: Phase 1 proved the firmware builds. Phase 2 makes it build automatically on a physical server I control, with a real ESP32 plugged into it, triggered by a Git push. This is where the "CI" in CI/CD stops being theoretical. A self-hosted GitHub Actions runner is now listening for code changes, building firmware, flashing it to hardware, and running serial validation tests.
DevOpsTL;DR: Most embedded teams still ship firmware by hand , a developer builds locally, flashes a board, pokes around, and calls it tested. This series documents building a complete automated firmware pipeline from nothing: reproducible builds, GitHub Actions, Python hardware test scripts, and eventually a self-hosted runner with a physical dev board wired directly into the CI system.
DashboardTL;DR: An Ideal Customer Profile (ICP) is the documented description of the exact type of company and person your business exists to serve. Without one, every marketing decision, the content you make, the channels you use, the words you write is essentially a guess. Only 48% of marketing teams have a clear, well-documented ICP. If you're in the other half, this post is your starting point.
HardwareFrom dipole to phased array, every antenna type serves a different engineering purpose. Learn what separates them - and why the wrong choice can derail your product launch.
DevOpsTL;DR: Docker Desktop is a RAM-hungry, license-gated bloat monster that runs x86 emulation on your ARM chip and acts surprised when things break. Podman, Colima, and Rancher Desktop each solve the problem differently - pick the one that matches how you actually work.
DevOpsDocker Desktop has a nasty architecture mismatch problem on Apple Silicon that breaks native-binary packages like LightningCSS. Podman is a drop-in replacement that runs ARM64 containers natively - no QEMU, no Rosetta, no chaos. If you're on an M1/M2/M3 Mac, skip the pain and start here.
AIAI is genuinely powerful — and genuinely overhyped. Here's what it actually does well, where it still fails, and how to use it without getting burned.
DevOpsSkip the bloated distros. I built a custom Linux OS from scratch for my Raspberry Pi 5 using Buildroot - SSH, UART for ESP32 comms, Python 3, and Verilator.
WebsitesThe scariest part of these types of attacks is that the attacker does not have to be the one to execute the code.
AIPeople throw these words around like they're the same thing. They're not. Here's how to tell them apart and why it matters for how you work.
AIAI stands for artificial intelligence and by the end of this article it will be more than just another buzzword.
