Some time ago I wrote about how to create a balanced binary search tree. The search keys and the data payload were both plain strings. Now it is time to get rid of this limitation. go2go lets us do that while waiting for the official generics release.

Ok, to be frank, this article is mostly about the second part of the title. We will build a market simulation with minimal Go code, and show how the rich get richer even when they are not greedy at all.

In the previous post, I used goreleaser to add binaries to a project release. Now let’s have goreleaser build a Homebrew formula as well. Automatically, and for macOS and Linux alike.

“go get” is a super-simple way of installing Go binaries, but not everyone has a Go compiler installed. If you want to make your CLI tools and apps available to the world, have a look at goreleaser.

Two questions for you: Do you name an app module simply “main”? And do you happen to write tests for a main package? If so, you are in big trouble! (Ok, that was a bit clickbait-ey…) Well, the world is not exactly going to end; however, you might encounter an unexpected error that is hard to track down.

Futures are mechanisms for decoupling a value from how it was computed. Goroutines and channels allow implementing futures trivially. Does this approach cover all aspects of a future?

Package what provides some handy debug-logging functions that can be enabled and disabled via build flags. No more information leaks in your production code!

Or: How adding goroutines can keep your CPU busy shuffling things around.

Just recently, Amazon announced support for Go on AWS Lambda. Here is a summary of last week’s news around this topic.

Pure data is for computers and nerds like you and me. Anyone else likes nicely formatted reports. Go and a good PDF package can help.
