A 2-line fix for a race condition in GStreamer’s shmsink that causes every pipeline using shared memory to exit with an error. How I found it, proved it, and verified the fix with sanitizers.
A step-by-step guide to mounting SMB/CIFS network shares on Linux — from one-off access in a file manager to persistent fstab entries with systemd automount that connect only when needed and gracefully handle VPN disconnects.
How a simple erase-remove in every add_timer() call turned entity registration into a quadratic bottleneck — and the 71x speedup from moving cleanup to the right place.
A hands-on walkthrough of configuring multiple monitors on Linux — from identifying displays with xrandr, turning off the laptop screen, ignoring lid close, to making it all survive a reboot. Every command explained.
Eigen’s blocked Householder path only existed for left-side application. I added the right-side equivalent, upgrading M*Q from O(n) rank-1 updates to cache-friendly blocked matrix multiplies.
How we built a GStreamer plugin suite for zero-copy NVMM video on NVIDIA Jetson, the bugs we hit along the way, and what it takes to contribute to the GStreamer project — from filing issues to getting an MR merged.
Everything I learned submitting four pull requests to ROS 2 core repositories — from finding issues and building in Docker to passing DCO checks, handling OSRF’s AI disclosure policy, rebasing across distro branches, and running the full test suites. A warts-and-all field guide.
Everything I learned contributing 6 PRs to PX4-Autopilot in a single session — from Docker-based builds and sanitizer workflows, through uXRCE-DDS session debugging and MAVLink signing analysis, to SITL integration testing. Real bugs, real fixes, real build output.
A three-day odyssey connecting PX4 flight controller to a GPU-rendered Unity drone simulation running headless inside Docker — through licensing labyrinths, shader abysses, coordinate system riddles, native library dragons, and a TCP protocol twist ending nobody expected.
Eigen’s .inc plugin headers were read by Doxygen but never preprocessed as C++ — meaning macros like EIGEN_PARSED_BY_DOXYGEN were silently ignored. Here’s how I verified it in Docker and what the one-line fix looks like.
