C++ project organisation (with gtest, cmake and doxygen)
...der files in an additional project-named subdirectory: "/prj/include/prj/foo.hpp", which seems redundant to me. Why not just "/prj/include/foo.hpp"? I am assuming that you will have an opportunity to re-jig the installation directories at installation-time, so you get <INSTALL_DIR>/include/p...
What is the difference between a URI, a URL and a URN?

http://example.com/resource?foo=bar#fragment
/other/link.html (A relative URL, only useful in the context of another URL)
URLs always start with a protocol (http) and usually contain information such as the network host name (example.com) and often a ...
HEAD and ORIG_HEAD in Git
...th modifiers like @{u} applied to it), but also affects e.g. "refs/heads/@/foo", which it shouldn't.
The basic idea of giving a short-hand might be good, and the topic can be retried later, but let's revert to avoid affecting existing use cases for now for the upcoming release.

Does C++ support 'finally' blocks? (And what's this 'RAII' I keep hearing about?)

// A class which uses 'mutex' and 'lock' objects

How does PHP 'foreach' actually work?
...r small variation, this time we'll assign the array to another variable:
$foo = $array;
foreach ($array as $val) {
var_dump(current($array));
}
/* Output: 1 1 1 1 1 */
Here the refcount of the $array is 2 when the loop is started, so for once we actually have to do the duplication upfront. Th...
Using getopts to process long and short command line options
...ns, use shorter non-ambiguous forms of long-options, use either the --file foo.txt or --file=foo.txt style, use either the -m 4096 or -m4096 style, mix options and non-options in any order, etc. getopt also outputs an error message if unrecognized or ambiguous options are found.
NOTE: There are ac...
C++ Modules - why were they removed from C++0x? Will they be back later on?
...and classes:
export {
int f(int);
double g(double, int);
int foo;
namespace Calc {
int add(int a, int b);

void not_exported_function(char* foo);
An important change of modules will be that macros and preprocessor definitions will be local to modules and...
The new syntax “= default” in C++11

What does the “Just” syntax mean in Haskell?
...ion of a null). Basically, if your function would normally return the type Foo, it instead should return the type Maybe Foo. If you want to indicate that there's no value, return Nothing. If you want to return a value bar, you should instead return Just bar.
So basically, if you can't have Nothing,...
Should I use SVN or Git? [closed]

Creating a repository is a trivial operation:
mkdir foo; cd foo; git init
That's it. Which means I create a Git repository for everything these days. I tend to use one repository per class. Most of those repositories are under 1 MB in disk as they only store lecture notes, hom...
