Game of Life is a simple simulation developed by John Conway. It uses a 2 dimensional array of cells, in each every cell can be either “alive” or “dead”. At each iteration of the process the application logic decides what will be the next status of the cell. This is done basing on the number of adjacent alive cells (including diagonals), and a set of following rules:

• If a cell has three neighbors that are alive, the cell will be alive. If it was already alive it

  will remain so, and if it was dead it will become alive.

• If a cell has two neighbors that are alive, there is no change in the state of the cell
• In all other cases the cell will be dead

Not so long ago I wondered how to add some protected fields into one of my GObject. Those of you who have more experience with Glib and GObject should know a very popular construct allowing to define and then add a private structure to a GObject class definition (with g_type_class_add_private).

As opposed to that, there is no such an easy mechanism which simplifies adding protected fields. Unfortunately when we use inheritance and virtual methods sometimes this can lead to some inconvenience and a lot of boilerplate code (which btw. in case of GObject library can reach a significant number of lines)

In my previous post I wrote about a strange bahavior of my freshly installed Ubuntu. One of the problems was related to sound. I managed to get it working. It came out that something had muted the PCM channel of my sound card. ( while updating from Ubuntu 8.04)

You can fix it by right clicking on the “Sound” icon next to menu bar, choosing “Open Volume Control” and moving up the slider next to PCM label.

Yesterday I found out that a new version of Ubuntu was released. Unfortunatelly I’m always excited in all the latest products and want to test them as fast as possible. That’s why I started to google for the safest and quickest possible way to upgrade.

My previous version of Ubuntu was 8.04 TLS, so I had to change some option in Software Sources dialog in order to make visible the latest version of Ubuntu.

I tried to build a Debian package for the project I am currently working on. Unfortunately all the paths I used in the structure of my application were very long. While executing make dist command I got lots of errors similar to the one below:
