What are the differences between json and simplejson Python modules?
...
On my Win7 PC (i7 CPU), json (CPython 3.5.0) is 68%|45% faster on simple|complex dumps and 35%|17% on simple|complex loads w.r.t. simplejson v3.8.0 with C speedups using your benchmark code. Therefore, I would not use simplejson an...

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!

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...
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(...

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 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...
