Benchmarks are merciless


A number 1/4 for A vs. B means that B is 4 times slower than A.

The Computer Language Benchmarks Game is more a community benchmark than a programming language benchmark. You get some ballpark figures that confirm what you already know beforehand: C++ is faster than Ruby :-)

But it's still depressing to see that a current implementation of JavaScript is faster than Python.

CodeIgniter likes the eval()

$ grep -r 'eval(' codeigniter/ | wc -l
20


Version 1.7.1. From the changelog: Fixed an arbitrary script execution security flaw

Well, who would have expected that?

"\'" in PHP

$ cat test.php
<?php
$string = "O\'Reilly";
echo $string, "\n";
?>
$ php test.php
O\'Reilly


That's documented but not expected.

Languages like Perl, Python, Ruby, Common Lisp, C, Scheme, OCaml, Erlang, Haskell, Tcl, JavaScript, etc. print the expected "O'Reilly".

One small stone you can stumble on.
