Double Takes

Whenever this kind of thing happens, the biggest mindset shift is not going from single tool to platform (though that's useful to translate to business use cases), it's what happens when you realize there's an entire ecosystem at play here. 🤯

TIL you can use redirect.github.com in links to avoid a back reference being created on github from commits, comments, PRs, etc.

Test-driven development is to programming what double-entry bookkeeping is to accounting.

Neal Lindsay

The fundamental character flaw of the software creator is not the misguided belief that they can solve any problem with software. Instead, it is the belief they can understand how their own software works before they create it.

We may need a SaaS appendix for Zawinski's law:

Any SaaS platform attempts to expand until it is a social network.

Why we coach the system, not just the team
Slow delivery isn’t usually about your people—it’s about your system. Shifting focus to incremental improvements in the system helps change not just processes but behaviors for lasting change.

Developer QA checklist for feature releases
Quality Assurance is a mindset integrated throughout development to catch issues early, build user trust, and reduce maintenance costs. These recommended procedures for dev teams without dedicated QA roles establish collective responsibility for ensuring feature stability, functionality, and usability before release.
