Should you declare methods using overloads or optional parameters in C# 4.0?
...
I'd consider the following:
Do you need your code to be used from languages which don't support optional parameters? If so, consider including the overloads.
Do you have any members on your team who violently oppose optional parameters? (Sometim...
Creating temporary files in bash
...predictable and the race condition it creates is
easy for an attacker to win. A safer, though still inferior, approach
is to make a temporary directory using the same naming scheme. While
this does allow one to guarantee that a temporary file will not be
subverted, it still allows a simple ...
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(...

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...
Unable to type in Visual Studio
... once I go back into the problem project I am unable to type in the editor windows. Not sure if it matters but the project that is giving me issues we are using SVN on.

Invoke(Delegate)

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...
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...
