Spurred by recent events (https://news.ycombinator.com/item?id=8244700), this is a quick set of jotted-down thoughts about the state of "Semantic" Versioning, and why we should be fighting the good fight against it.

For a long time in the history of software, version numbers indicated the relative progress and change in a given piece of software. A major release (1.x.x) was major, a minor release (x.1.x) was minor, and a patch release was just a small patch. You could evaluate a given piece of software by name + version, and get a feeling for how far away version 2.0.1 was from version 2.8.0.

But Semantic Versioning (henceforth, SemVer), as specified at http://semver.org/, changes this to prioritize a mechanistic understanding of a codebase over a human one. Any "breaking" change to the software must be accompanied with a new major version number. It's alright for robots, but bad for us.

SemVer tries to compress a huge amount of information — the nature of the change, the percentage of users that wil

Git vs. CVS Advantages

Flexible Workflow

In Git your working copy is a clone of the entire repository. This includes branches and tags. This decreases the overhead (speed and manual work) involved when switching contexts and the need to be connected to a network. Some examples are:

• When switching branches there is no need to connect to a remote server or close your IDE/project and open a checkout in another directory. Running git checkout [branch name] is all you need to do.
• When merging you do not need a connection to the remote server, you have all branches locally. Since branches are so cheap in Git you could create a new branch to perform the merge in so that if you had a large amount of conflicts you could incrementally work on and commit without affecting the main branch then merge or create a patch after everything has been fixed.
• Because Git is a distributed system in addition to connecting to a central repository developers can connect to another developers repository. This allows team
