Software development cheat sheets

These are working references, not tutorials. Each one assumes you already write software and need the command, the default, the tradeoff table or the decision rule without reading a chapter. Git gets two pages: one for the commands you type and one for the object model underneath them, because the second explains every confusing thing the first does.

The architecture pages (.NET clean architecture, API design, microservices, observability, the database comparison) are written for the person who has to choose, so each leads with a comparison table and a rule for when to use which. The language pages (Python and JavaScript for architects, .NET and C#, language design tradeoffs) cover the current versions and date anything that will drift.

If you work on a .NET team, the software development guides hub routes by role. If you just need the command, use the search box; it indexes every section heading on every page.
