Fail fast\fail early

Fail-Fast (sinngemäß „schneller Abbruch“) bezeichnet die Eigenschaft eines Systems, Fehler frühzeitig zu erkennen. Ein Fail-Fast-System ist so konzipiert, dass es an seinen Schnittstellen Fehler oder Zustände, die zu Fehlern führen, erkennt und aufzeigt. Üblicherweise beenden sich Fail-Fast-Systeme im Fehlerfall selbst und versuchen nicht, mit dem Fehler weiterzuarbeiten

Buckling-Spring! => IBM Model M

Die Model-M-Tastatur bezeichnet eine Computertastatur-Gattung, die auf die zwischen 1984 und 1999 von IBM millionenfach hergestellte Tastatur „Model M“ zurückgeht.

Insbesondere die Cherry MX switches erzeugen einen spürbaren „Rückschlag“ beim loslassen… was das original nicht macht.

Patterns for Managing Source Code Branches from Martin Fowler

Like most software patterns, few of them are gold standards that all teams should follow. Software development workflow is very dependent on context, in particular the social structure of the team and the other practices that the team follows.
In thinking about these patterns, I find it useful to develop two main categories. One group looks at integration, how multiple developers combine their work into a coherent whole. The other looks at the path to production, using branching to help manage the route from an integrated code base to a product running in production.
