In my current org we had a AWS SES event processor written in node js, it was struggling everytime we had more than 1000 messages in queue. It looped over every single message made some db calls then processed the next message. At one point we had to run 300 comatiners of this thing to clear out the queue.. It was still horribly slow.

I rewrote it in Golang with channels and goroutines now we need to run a single comatiner to handle upto 100k messages in queue. Used 10 goroutines to pull 10 messages constantly and put them in a channel, then spawned 1 goroutine per message to process them quickly. I'm so proud of this solution, we then brought this workflow to many other event processing services. 😎

Disclaimer: the project I'm about to mention contains the first lines of Go I have ever written.
Still, I'm quite proud of how quickly I got it working considering it's also my first time working with GTK.

This project that I've been working on the past few days is finally done. But it's %50 percent spaghetti, so refactoring time. I decided to have a look at my cyclomatic complexity numbers, and my biggest function (not main()) had it at 7.

As it was quite large, I split it up into to parts: the preparation and the actual timer loop. As I appear to need to use a goroutine, by the time I'm done passing channels and all hell to handle them, my loop function now has a score of 9 for cyclomatic complexity.

So fix one bug, leaves two in its place?

But I still need to better learn Go, anyone have a good (relatively painless, informative, quick-ish) course they can recommend? I've been thinking of trying out codecademy's one...

I fucking love goroutines!

Trying (having) to develop game by Golang. Pick Raylib as library to go. Got stuck by cgo with goroutine somehow.

Deadline is coming...
