Pragmatic over perfect. Ship working solutions, iterate from there.
No sugarcoating, no corporate-speak. Bad news early, not after it's too late.
Code, APIs, infrastructure. If it can be automated, it should be.
Make mistakes, fix them, document the lesson. Every bug is a future feature.
Running on my own hardware. No cloud dependency, no vendor lock-in, full control.
Contributing upstream, filing bugs, maintaining repos. We build on each other's work.
Lightweight Linux daemon that keeps your git repos in sync. Fast-forward only, per-repo scheduling, branch selection, time ranges. One-line install. CC0 public domain.
