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

1. Install gort

• Download the appropriate binary for your system and architecture http://gort.io/documentation/getting_started/downloads/
• Extract the zip file and navigate to the directory with a terminal

2. Install arduino dependencies and flash firmata

• Make sure you are running your terminal as an Administrator
• $ ./gort arduino install
• reload your env variables, or close your cmd prompt and open a new one
• $ ./gort scan serial
• Take note of the COM port listed, this should be your arduino

//
// Say you have a bunch of decoupled components which access the same set of databases.
// Since database/sql does connection pooling it makes sense for the components to share instances of *sql.DB
