So you are totally new to programming on a computer and you want to see how programs are done. The usual recommendation is "find a problem that you like and attempt to solve it using a programming language of your choice". In other words, if you already have the hang on how to write computer programs and you want to learn a new language, say Ruby, then you just need to try to solve known problems.
Here is a simple problem and its solution written in very simple Ruby. We will be writing a program that tests the speed of our network connection to the Google DNS 184.108.40.206. You will need Ruby 1.9 to get this to work properly, as well as the net-ping gem. On an Ubuntu (11.10) system you can get these by doing:
In other words, you need a hash (key,value) that contains arrays which are hashes themselves. That would make it easier to navigate them and print anything you would like. (This is very common when parsing formatted text like XML files and so on).
Although is in the "universe", the upcoming release of Ubuntu 11.10 will include Gnome 3! That would mean that we no longer need to include PPAs from third parties or go through different bug tracking systems when something needs fixing.
I'd probably enjoy more if Ubuntu's team drop Unity altogether and ported whatever functionality to Gnome 3 so this would be the "official" display manager once again. However, I'm content to use this from Universe for now.
As you already know, MacOS X allows you to quickly share your internet connection with others with a few clicks. However, what if you want to share your connection using your bluetooth device in the same way that the iPhone personal hotspot works?
Say you are in a strange place or your computer does not have the wifi drivers and you need to connect to the internet quickly. You can share your Macbook connection by following these simple steps.
