Trick of the day: prefetching a callback into the QApplication event loop
Qt provide a standard mechanism (aboutToQuit() signal) to insure that a callback is executed at the end of the QApplication event loop. This is typically used to add some cleanup code to your application. Infortunately, Qt does not provide a “aboutToRun()” if you want to execute an initializing code just…
The LD_PRELOAD trick
If you ever wanted to replace some symbol in a library, in order to inspect what happens in a binary you don’t have the source code or even to inject some code, this can be done using the LD_PRELOAD trick. To use it, invoke your binary as such: $ LD_PRELOAD=somelib.so…

The Bulk Synchronous Parallel model for graph processing
The BSP Model The Bulk Synchronous Parallel (BSP) is a model for designing parallel algorithms. The BSP model was developed by Leslie Valiant of Harvard University during the 1980s and published in 1990. Computation proceeds as a sequence of iterations, called supersteps. Each superstep involves a phase of parallel computations,…
