Memory bugs are tricky. Leaks have a clear impact on performance, and quickly become hard to spot when heap allocated objects move too much. Memory access bugs, on the other hand, make your program crash right away, if you’re lucky. In less desirable cases, they may end up corrupting random objects on the heap, and […]

Creating Python bindings for Qt libraries
Python is a handy all-purpose language. It can make you very productive within a short time period and has powerful expressiveness for data manipulation and processing.
