Command line: piping find results to rm
... intend to use with
-delete, you should explicitly specify -depth in order to avoid
later surprises. Because -delete implies -depth, you cannot
usefully use -prune and -delete together.
P.S. Note that piping directly to rm isn't an option, because rm doesn't expect filenames on stan...
Hash Code and Checksum - what's the difference?

How to find out element position in slice?

Another option is to use higher order functions and closures for creation of generic functions. I added answer with an example.

Naming convention for utility classes in Java
...ed to name and address and the other contains utility functions related to orders, then call them CustomerNameAndAddressUtil and CustomerOrderUtil or some such. I regularly go nuts when I see meaningless subtle differences in names. Like just yesterday I was working on a program that had three field...
How do I check if a string contains a specific word?
...g_match 1.5 seconds to finish and for strpos it took 0.5 seconds.
Edit:
In order to search any part of the string, not just word by word, I would recommend using a regular expression like
$a = 'How are you?';
$search = 'are y';
if(preg_match("/{$search}/i", $a)) {
echo 'true';
}
The i at the en...
What is the difference between float and double?
... of the value 2^24 followed by 2^24 repetitions of the value 1. Summing in order produces 2^24. Reversing produces 2^25. Of course you can make examples (e.g. make it 2^25 repetitions of 1) where any order ends up being catastrophically wrong with a single accumulator but smallest-magnitude-first is...
What is the difference between concurrency, parallelism and asynchronous methods?
...lit up into units (units essentially being threads) that can be ran in any order and have a determinate outcome. Parallel means these units/threads are being ran literally at the same time on multiple processors.

Why malloc+memset is slower than calloc?
...The performance difference here is much larger (I measured more than three orders of magnitude on my system between malloc()+memset() and calloc()).
Party trick
Instead of looping 10 times, write a program that allocates memory until malloc() or calloc() returns NULL.
What happens if you add mems...
Vertically centering a div inside another div [duplicate]
...
+1, but it curiously depends on the order of positions. Starting bottom: 0; left: 0; gets the inner div stuck on the bottom of the parent (Chrome 33, anyways).
