    MindMap app using Hyperbolic tree

    • 2 Comments
    I recently came across a Hyperbolic tree implementation on codeplex using WPF and thought that a nice usage of it could be in writing a mind map creating application.... I tweaked some of the original code and got a tree with editable nodes... Its been laying around for sometime, so I thought it best to put it out there so that you folks can continue its development.

    ABCs of Threat modeling ...

    • 2 Comments
    Larry Osterman has an interesting series of posts on Threat modeling.. It starts from the basics and is very comprehensive. A application needs to go through the threat modeling process to identify possible threats, the mitigations, and the risks involved. From a tester's perspective it opens up several testing scenarios. So if you are unfamiliar with this topic or its something which needs some brushing up, give the posts a look :) ... Happy reading Share this post
