When using CUDAfy.NET, if you encounter the “Compilation Error” when running examples, simply add “cl.exe” to your PATH! It will resolve the translator exceptions. It’s funny how I didn’t find much about it online…

Carve is a fast and robust library for performing Constructive Solid Geometry (CSG) operations (boolean operations) on meshes. In case the mesh is corrupted or has self-intersections, Carve will refuse to perform operations on it and will terminate with this error: “didn’t manage to link up hole!”. To solve that, simply open the mesh in …

In .NET, the List<> class is serializable. However, you should note that during a call to the deserialization constructor of the objects the list contains, the list will be empty. All operations on the newly deserialized objects (such as value checking and so on) need to be performed in another function marked by the [OnDeserializedAttribute] attribute. …

One popular BLAS implementation under Windows is AMD’s ACML. CMake has some modules that can find certain required dependency libraries. As far as I know, under Windows the “FindBLAS” and “FindLapack” modules are unable to locate AMD’s ACML libraries. This is because ACML > v4.0 does not include the “mv” related packages anymore. I looked …

You probably don’t know that they are not only accessors but also mutators! You can simply assign a direction vector to an …

If your C/C++ code works fine under a certain build configuration (eg. Release) but not under another (eg. Debug) or simply works fine when built with a certain compiler, it is a sign that the code is not robust and some small detail which depends on compiler optimization is producing undefined behavior. For instance, my …

On Linux, you may occasionally encounter the error “dlopen: cannot load any more object with static TLS” in MATLAB. This is a known bug since way back! To fix, create a file “startup.m” in the directory that you start MATLAB from with the following content: ones(10)*ones(10); I know! It’s ugly… But it works!! EDIT: Since it …

After getting an SSL certificate, it is usually good idea to redirect all http (port 80) connections on your website to https (port 443). This can be simply done in Apache. To do this, just go to your public_html folder and either create a .htaccess file and add these lines, or add them to the already existing .htaccess file: …
