Project: Vulnerability of wireless networks


There are a lot of open wireless networks (ie. airport, coffee shop, (fast-food) restaurant, …). The reason is usually because they use a web server to manage the clients and payments or just want to supply free internet. This type of open networks are very unsafe. The exploit I will explain relies on a open network. Another thing it relies on is that people that frequently visit these locations will allow their device to connect automatically because they don’t like to click.

What devices that have “connect automatically” networks do is send probe requests to the networks asking any network access point in reach to answer if it is one of those networks. Continue reading

A Chrome Extension: Mobile Vikings Balance

Two months ago I changed my mobile provider to Mobile Vikings.

Mobile Vikings has a very easy way to check your balance online or on the go. Even though I kinda think it takes too long to load. They have an even better API. Since my browser of choice is Chrome, I decided (yesterday) to make a small extension to check my balance in the background. This is my result until now. (most recent source code can be obtained if you contact me)

Everybody who is a Viking and uses Chrome should use it. Updates will be automatically installed. So why not try it?

Silverlight pokerclock

PokerclockI have created a pokerclock in Silverlight. For all of you who are interested in playing a poker tournament. Feel free to test it out.


  • A preset of blind structures has been entered for a easy configuration.
  • You can enter all the players and generate a random seat-number for them. The one marked in red will be the dealer in the first hand.
  • You can edit the blind structures and enter some information about the tournament so the payouts and average stack can be calculated.
  • The clock beeps at the 1 minute mark and warns you each time the blind levels go up.
  • You are able to skip blind levels and pause the tournament.
  • Out of browser is supported so that it can be used without internet access.

Cheap ASP.NET hosting (discontinued)

This promotion has been discontinued because hostbasket has been bought by Telenet. And as we know they don’t do promotions that are amazing!

I have been looking for quite some time for a good host. And since I am a student I would like it to be as cheap as possible. Last year I found a decent free host. But I couldn’t use the .net power at it’s best because it only supported the .net framework 2. It also had advertisements and it was very slow.

A month ago I had this discussion with a fellow student about this very problem. He said there was a host that was very cheap for students. That is how I came across I’ve been using it for a week now and I must say it really amazes me what I get for only 1,21€/year. My hostbasket domain runs on a Windows Server 2008 and has  .NET 3.5 and SQL Server 2008.

I will use my new domain to publish the projects I will be developing. Stay tuned.

Hello world!

I would like to use this post to explain a little about what this blog is for and how I plan to use it. As some of you may know, I am a computer scientist. And in computer science there are so many things that are very important to me.

So I am going to use this blog to talk about the projects I am working on and important things to me. This blog is mainly for myself, so I have a portfolio of projects I have done.

But if you like what you read, I am happy to welcome you to this blog. Feel free to contact me if you are looking for code or help about my projects.
