What is the best way to count “find” results?
...time find -type f -printf '.' | wc -c
8
real 0m0.004s
user 0m0.000s
sys 0m0.007s
With full lines :
$ time find -type f | wc -l
8
real 0m0.006s
user 0m0.003s
sys 0m0.000s
So my solution is faster =) (the important part is the real line)

How to use R's ellipsis feature when writing your own function?
...
You can convert the ellipsis into a list with list(), and then perform your operations on it:

$a
[1] "character"
$b
[1] "numeric"
So your ...
Why does string::compare return an int?
... Similarly, if I write a < 0, the comparison is done

Why does the Scala compiler disallow overloaded methods with default arguments?
...lly I added an implicit conversion to the class in one case which did just convert the alternative type to the type accepted. It just feels ugly. And the approach with the default args should just work!
