Recursive Lock (Mutex) vs Non-Recursive Lock (Mutex)
... functions by themselves need to lock the mutex, then recursive mutex is a win-win.
For any other case (solving just bad coding, using it even in different objects) is clearly wrong!

Can hash tables really be O(1)?
... your runtime depends on the dataset you're running on.
Consider the following pseudocode of the get method of a hash table. Here I'm assuming we handle collision by chaining, so each entry of the table is a linked list of (key,value) pairs. We also assume the number of buckets m is fixed but is O(...
C++11 std::threads vs posix threads
...en if C++11 seems available. For instance in native Android std::thread or Win64 it just does not work or has severe performance bottlenecks (as of 2012).
A good replacement is boost::thread - it is very similar to std::thread (actually it is from the same author) and works reliably, but, of course...

The answer to this question lies in how C# Controls work
Controls in Windows Forms are bound to a specific thread and are not
thread safe. Therefore, if you are calling a control's method from a
different thread, you must use one of the control's invoke methods to
marshal the call to the...

What exactly are DLL files, and how do they work?
...ere are 2 types of libraries. Static libraries and dynamic libraries. In windows the file extensions are as follows: Static libraries (.lib) and dynamic libraries (.dll). The main difference is that static libraries are linked to the executable at compile time; whereas dynamic linked libraries ar...
What is the optimal algorithm for the game 2048?
... in action or read the source.
Currently, the program achieves about a 90% win rate running in javascript in the browser on my laptop given about 100 milliseconds of thinking time per move, so while not perfect (yet!) it performs pretty well.
Since the game is a discrete state space, perfect informa...
