Screencast: Debugging with Emacs & GDB

Christopher — Wed, 04 Nov 2009 00:29:18 +0000

Hey there.
I wish I’d be posting more recently, but haven’t really had the time to do so.
I just wanted to share with you a small screencast I created today on debugging with emacs and gdb, since I think it might be of interest to someone else as well.

You can check out the video at my blip.tv channel: http://bakkdoor.blip.tv/
Currently the video is being converted to flash video (.flv), so you might want to check out the .ogv video file here, if it’s not done yet: http://blip.tv/file/2804484

[Update:]
Video is available now. You can also watch it here:

Anyhow, I hope you like it and I’d like to hear some feedback.

Btw, the programm I’m debugging in the video is stupidvm, a small & stupid virtual machine I’ve started working on 2 weeks ago, written in C.
You can check out the code either on gitorious or github.

Feedback is, as always, welcome
I hope you like it.

This is the 5th episode on creating a simple game in Ruby. In this episode, we’ll add some automated testing via the BDD framework RSpec. We’ll also start to implement the Character class.

Screencast series: Creating a simple game in Ruby – Episode I

Christopher — Tue, 12 May 2009 14:59:25 +0000

Today I started a new screencast series, titled “Creating a simple game in Ruby”.

Basically, I show how to create a simple (very simple) game in Ruby form scratch. Beginning with a simple text-based interface, I’ll slowly move on to a more sophisticated graphical user interface (written with the GUI library Shoes by _why) and explain my design decisions etc.

The reason I’m doing this is, that I’ve started writing a little game together with my girlfriend, since she wanted me to teach her a little about programming in Ruby. The idea for the game came from her.

Basically, the game is a Tamagotchi-Clone (called “Jimi”), where you have a little “virtual pet” you have to take care of, feed it etc.

Nothing very special, but I thought other newcomers to Ruby might be interested as well and could also learn something, hence the screencast.

I’ll post more videos, as I finish them.

Have fun watching them and leave some comments, if you want to.
