Handmade Penguin is a companion to Casey Muratori's amazing
Handmade Hero series. As the name suggests, Handmade Penguin chronicles how to follow along if you're
using the Linux operating system. Casey will be spending a few weeks covering porting the game to different
platforms, but for those of us who want to follow on from the beginning, hopefully this will help. Notably,
this is not a tutorial by itself, but more a list of things you need to change to get the game working. It will
therefore probably fizzle off after a couple of weeks when all of the platform-specific code is done.

This is aimed at people who are comfortable using (and programming) on Linux, as it's neither an intro to Linux tutorial
nor an intro to programming tutorial. Of course, the best way to know if it suits you is to try to follow along with the first few
chapters and see if you understand it and/or like it!
I'll be developing using Kubuntu Linux and using the KDevelop IDE for debugging (with an editor of your choice for the actual coding). I think Casey is probably going to be using Linux Mint which is just as good. You should be able to follow along with most of it on your own Linux distro or IDE with very little

A Note on SDL
A few people have asked why Handmade Penguin is using SDL, whereas Casey is not going to use any non-system libraries.
There are a couple of reasons for this. Firstly, SDL is much easier to use than calling X11 directly: if I were using X11, there's no way I'd be able to write
these without falling behind. Secondly, while doing things from scratch is an excellent learning experience, once you're comfortable with how things work under
the hood, using a library like SDL is really the right way to go: most of the SDL code we use works without modification on other platforms, and all of the nasty
bugs and issues with X11 and the like are already worked out for us. I've done QA for a lot of Linux games, and the ones that used SDL were significantly
less buggy than those that used X11 directly.
Besides, since Casey is going to be doing a Linux port later anyway, it'd be boring to do exactly the same thing twice!
I'm looking forward to sailing on the Cs of adventure with you all!
