Getting started with Haskell
...capable of anything, with enough skill. It is very fast (behind only C and C++ in my experience), and can be used for anything from simulations to servers, guis and web applications.
However there are some problems that are easier to write for a beginner in Haskell than others. Mathematical problems...
How to avoid reverse engineering of an APK file?
...e option of including shared libraries, you can include the needed code in C++ to verify file sizes, integration,
etc. If you need to add an external native library to your APK's library folder on every build,
then you can use it by the below suggestion.
Put the library in the native library path w...
boost::flat_map and its performance compared to map and unordered_map
...e Loki AssocVector, but with some supplementary modernizations coming with C++11, exploiting move semantics to accelerate insert and delete of single elements.
This is still an ordered container. Most people usually don't need the ordering part, therefore the existence of unordered...

When is the thread pool used?
...ot the whole picture.
Certain functions and modules, usually written in C/C++, support asynchronous I/O. When you call these functions and methods, they internally manage passing the call on to a worker thread. For instance, when you use the fs module to request a file, the fs module passes that ...
How can I efficiently select a Standard Library container in C++11?
There's a well known image (cheat sheet) called "C++ Container choice". It's a flow chart to choose the best container for the wanted usage.

...nswer, I'm writing this.)
This problem arises in newer versions of Visual C++ (the older versions usually just silently linked the program and it would crash and burn at run time.) It means that some of the libraries you are linking with your program (or even some of the source files inside your pr...
Regex Pattern to Match, Excluding when… / Except between
...not the only option. The .NET regex flavors found in C#, VB.NET and Visual C++ for example, as well as the still-experimental regex module to replace re in Python, are the only two engines I know that support infinite-width lookbehind. With these tools, one condition in one lookbehind can take care ...
