Hardening attack surfaces with formally proven binary format parsers
With an eye toward performance, interoperability, or legacy concerns, low-level system software often must parse binary encoded data formats. Few tools are available for this task, especially since the formats involve a mixture of arithmetic and data dependence, beyond what can be handled by typical parser generators…

Xcode Constantly Phones Home
Building StopTheMadness Pro in Xcode is usually very fast, because my project doesn't use any Swift. It's a combination of Objective-C, which compiles much more quickly than Swift, and JavaScript, which doesn't need to be compiled. However, sometimes the builds were very slow for some strange reason. Checking the…

Predicting the next Math.random() in Java
A while back a friend of mine hosted a programming competition where you were given 9 random numbers one at a time and you had to guess the rank (the sorted position amongst the 9) of each as they are coming in. The goal was to submit a strategy in Java that will maximize the number of these games won. The best…

Hilbert space: Treating functions as vectors
The tools of linear algebra are extremely useful when working in Euclidean space (e.g. \mathbb{R}^3 ). Wouldn’t it be great if we could apply these tools to additional mathematical constructs, such as functions and sequences? Hilbert space allows us to do exactly this - apply linear algebra to functions.

Sorting algorithms with CUDA
Building on my previous post on sorting algorithms, I implemented the same algorithms using CUDA to explore performance improvements through parallel computing. The goal is to see how we can leverage the power of parallel computing to speed up our sorting algorithms. I went for a NVIDIA recruiting event some days ago…
