Encrypt chat conversations in Pidgin using pidgin-otr

Posted in Articles, Security by Patrick on March 17, 2009

Pidgin is an excellent “chat client” or instant messaging client. I’ve even replaced the MSN client on my Windows system with Pidgin. It’s open source and has support for many different chat networks like MSN, ICQ…

There’s a plugin called pidgin-otr (Off-the-Record messaging) which allows you to encrypt your conversations (assuming the other part also has pidgin-otr installed). Regretfully, people never seems to care about encryption even if they seem to get close to crazy if someone invades their privacy, quite the paradox… Well that’s just another story which i’m not going to post here, as i’m just spreading the word about everything that’s good : )

The Off-the-Record messaging plugin uses public and private keys. It’s very easy to use. Just download the plugin, activate it in the Pidgin add-on menu and generate a key. In the conversation window, a button will appear that makes it easy to toggle encryption on/off.

Tetris game in Python

Posted in Uncategorized by Patrick on March 20, 2008

We’ve had a project in school this year and this is the thing I came up with. It’s a Tetris clone coded in Python using the library PyGame. Unfortunately, I won’t release the source code for this game, I have my reasons : )

I took some things into consideration when I made this game (game play wise). I’ve tried many different versions of Tetris before and become very frustruated because the rotation and block types are different than they use to be. That’s why I tried to make this Tetris clone as much alike the standard version as possible.

How to play
The block is controlled by the arrow keys and you can rotate the block with the UP-key and move the block fast with the DOWN-key.

I’ve added a web highscore system so players can upload their scores.
