Take a Unity Screenshot with Alpha
This script takes a screenshot and saves it to the user desktop. It has options to use an alpha background, and also upscale the image. Useful for taking pictures of a scene or model for composition by artists.

Building fast, quality network server programs with Go.
I've been investigating and learning Go. There is a lot of high quality tools out there, for example:
- xo generates types and functions to match your SQL schema, and
- goa lets you design a REST api using a DSL, then generate the code to implement that API!
Compile time for Go is super fast, and so is the built executable. I'm using vim for the IDE, and it has excellent support for Go, including autocompletion which is great when you're learning the language.
