Go Pipelines

This document demonstrates a basic pipeline in Go and talks about a risk in in implementing them. Keep in mind that:

  • Using FizzBuzz here is contrived, but quite a nice way to demonstrate the concept. Obviously there is no advantage to running the basic workload of FizzBuzz in a Goroutine, but if the task involved heavy computation or long lived I/O, it starts to make a lot more sense.
  • The problem discussed only applies to Goroutines that actually need to have a way to

True Colour (16 million colours) support in various terminal applications and terminals

Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

  • Plain ASCII
  • ANSI escape codes: 16 color codes with bold/italic and background
  • 256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
  • 24-bit true color: "888" colors (aka 16 milion)
You can’t perform that action at this time.
