⚡️ Git Integration Still Feels a Decade Away
After years of updates, even Visual Studio’s 'improved Git integration' feels half-baked. For many developers, seamless VCS workflows remain a mirage—commercial nuclear fusion might realistically beat perfect Git UI to market. It’s a reminder of how stubbornly complex core dev tooling can be, despite all the AI hype around it.

⚡️ Fixing High CPU Burn on GitHub Actions Runners
Self-hosted GitHub Actions runners can chew through CPU even when idle — one core locked at 100%, by design. The culprit is a busy-wait loop in the runner’s sleep logic, not your workflows. Digging into the code reveals a simple but costly tradeoff between responsiveness and efficiency.
