Why We Need a Dark(er) Web

For Securelink‘s Checkup 2017 event, I gave an updated talk about the state of internet surveillance/censorship and proposing a Dark(er) Web as a solution. It is an extended version of my previous talk on the subject. In the first part of the presentation, I pose that the internet is broken …

Spoofing e-mails from BE government domains

After reading about some journalists discovering how easy it is to spoof mail addresses of certain positions within the Dutch government, I decided to check what the situation was in Belgium. Spoofing a mail address is a technique/prank as old as the internet itself  – the most popular mail protocol …

cuda2GLCore: CUDA to OpenGL textures

I made a new implementation of the Cuda2GL sample provided in the CUDA Samples by Nvidia. The sample shows how to generate a texture in CUDA and use it in an OpenGL context without copying it to main memory. The original implementation uses Glut and OpenGL immediate mode (Compatibility profile) to draw the resulting texture. The sample …

TriMesh2 Fork – A library for 3D mesh editing and I/O

During my first years in graphics development, I relied heavily on Szymon Rusinkiewicz’s C++ TriMesh2 library. It’s a nice set of tools for 3D mesh input/output, basic visualization and processing. I’ve come to use it in most of my projects. It imports .obj, .3ds and .ply files (amongst others), and puts …

CUDA Voxelizer v0.1

Time to release something that’s been gathering dust on my hard drive for a bit too long: I wrote a CUDA-accelerated voxelizer. It converts polygon meshes into annotated voxel grids. You can download source code and executables on Github. Written in C++ / CUDA Outputs data to .binvox file format …

Flashing system images on Moto X Play

Another Android phone, a new roundabout way of getting control over it. I purchased a Moto X Play last year (review: great battery capacity, good performance, huge phone though), and recently found myself in the situation where I had to manually flash a stock firmware image. This is the first non-Nexus …
