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

New ES6 Constructor Semantics and Usage Examples

Manual super: Alternative Design where subclass constructors do not automatically call superclass constructors

This Gist presents a new design of class-based object construction in ES6 that does not require use of the two-phase @@create protocol.

One of the characteristics of this proposal is that subclass constructors must explicitly super invoke their superclass's constructor if they wish to use the base class' object allocation and initialization logic.

An alternative version of this design automatically invokes the base constructor in most situations.

Introduction

This script lets you set up and use a temporary DigitalOcean droplet to download torrent files.
Once downloaded, they can be streamed down to your local machine.
This uses transmission-cli for the torrent client, and nginx to serve files.

Setup on Local Machine

This assumes that you have a DigitalOcean account and tugboat set up, as well as seedbox-setup.sh present in the current directory.

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
