Buffered Channels In Go — What Are They Good For?
Post 3 in a Series on Go In a previous blog post we looked at how to build an unbounded channel, where writes to the channel would never block. It was built on top of two unbuffered channels, a goroutine, a slice, and a couple of closures. Notably missing was a buffered channel. Buffered channels never have unlimited buffers. Proper use of a buffered channel means that you must handle the case whe

Special Processes in OTP
On a recent Elixir project, I needed to test some asynchronous behaviour. Doing so led me to learn about the basics of special processes in OTP. Our project was using Phoenix Channels and had a need to keep track of all connected socket processes. We could have used the upcoming Phoenix presence feature, but we didn’t quite need all of its features. We settled on using a simple GenServer process t

Package time provides functionality for measuring and displaying time. The calendrical calculations always assume a Gregorian calendar, with no leap seconds. Monotonic Clocks ¶Operating systems provide both a “wall clock,” which is subject to changes for clock synchronization, and a “monotonic clock,” which is not. The general rule is that the wall clock is for telling time and the monotonic clock

What are channels used for?
GitHub - sbogacz/go-pipeline: go-pipeline is a Go library to provide some channel "middleware"-like functionality. It can lead to some clean code when processing various inputs that share a flow.
