Update: i also found the dependency list on the ebiten wiki: https://github.com/hajimehoshi/ebiten/wiki/Linux#fedora

Second: and it is now found on the new website https://ebiten.org/install.html#Fedora

a few weeks after i ported Impact.js to the modern world (some writing about this adventure will follow), i found another interesting engine, this time written in go.

the engine is called ebiten and has a pretty low-level api, but compiles to all desktop and mobile platforms - so i want to give it a try

Picking up go is a lot of fun! So does a few of my colleagues :-)

Tobi M. (“the destroyer”) asked if i have a solution to run a golang docker image with the go-sqlite3 driver

I remembered to had the same problem, so after my post about really small docker images, lets add a few more bytes!

the solution

This solution is not my own, i found and tried other solutions but stayed with this Dockerfile on github

Long, long time ago, i started to manage my spare time projects with git, to make life a bit easier there were tools like gitosis and later gitolite - you managed repositories and public keys in plain text files and git hooks on the server. Last year i decided to join the shiny new world of modern self-hosting git services. I choose Gitea - copied it on the server, started one 40 mb binary, and it was just working - and it was fast.

for my presentation tool slide-serve i used fsnotify to watch for changes to reload the browser. But for whatever reason, the events always came in doubled… so i tried to port the idea behind the underscore or RX debounce function to golang. This is the solution i came up with:

func debounce(interval time.Duration, input chan string, cb func(arg string)) {
	var item string
	timer := time.NewTimer(interval)
	for {
		select {
		case item = <-input:
			timer.Reset(interval)
		case <-timer.C:
			if item != "" {
				cb(item)
			}
		}
	}
}

usage

in this example, the debounce time is one second, the input eventChanel is created to send events to debounce. The actual processing happens in the callback function.
