How do I find where an exception was thrown in C++?
...and often is, located in a different function/method than the point of throwing. It has also been pointed out to me in the comments (thanks Dan) that it is implementation-defined whether or not the stack is unwound before terminate() is called.
Update: I threw together a Linux test program called t...
Using @property versus getters and setters
...
The short answer is: properties wins hands down. Always.
There is sometimes a need for getters and setters, but even then, I would "hide" them to the outside world. There are plenty of ways to do this in Python (getattr, setattr, __getattribute__, etc..., ...
Why should I avoid using Properties in C#?
...
write-only; field access is always
readable and writable.
This is a win for properties, since you have more fine-grained control of access.
A property method may throw an
exception; field access never throws
an exception.
While this is mostly true, you can very well call a method on...
How to change the output color of echo in Linux
... to the terminal's default
tput bel # Play a bell
With compiz wobbly windows, the bel command makes the terminal wobble for a second to draw the user's attention.
Scripts
tput accepts scripts containing one command per line, which are executed in order before tput exits.

Determining complexity for recursive functions (Big O notation)
...4, even though the result is the same, shouldn't the induction be the following? T(n) = a + 2T(n-1) = a + 2a + 4T(n-1) = 3a + 4a + 8T(n-1) = a * (2^n - 1) + 2^n * T(0) = a * (2^n - 1) + b * 2^n = (a + b) * 2^n - a = O(2^n)

What do 'statically linked' and 'dynamically linked' mean?
... form an executable.
The distinction is made for, among other things, allowing third party libraries to be included in your executable without you seeing their source code (such as libraries for database access, network communications and graphical user interfaces), or for compiling code in differe...
What's “P=NP?”, and why is it such a famous question? [closed]

How can I pair socks from a pile efficiently?
...ent than a modern CPU, this question makes no practical sense.
Humans can win over CPU algorithms using the fact that "finding a matching pair" can be one operation for a set that isn't too big.
My algorithm:
spread_all_socks_on_flat_surface();
while (socks_left_on_a_surface()) {

What are the differences between Autotools, Cmake and Scons?
... a painful experience to get an Autotools setup to build usable code for a Windows system. (While I've little use for Windows, it is a serious concern if you're developing purportedly cross-platform code.)
When it breaks, you're going to spend HOURS chasing your tail trying to sort out the things t...
