Using getopts to process long and short command line options
...rm described above. With the use of getopt, however, you can group single-letter options, 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 outpu...
What is move semantics?
... ^ the moved-from temporary dies right here
Note that the letters l and r have a historic origin in the left-hand side and right-hand side of an assignment. This is no longer true in C++, because there are lvalues that cannot appear on the left-hand side of an assignment (like array...

Finding a branch point with Git?
...e G commit, instead of the A commit.
So, I've created the following tree (letters assigned in chronological order), so I could test things out:
A - B - D - F - G <- "master" branch (at G)

This looks a little different th...
