Found this article today which had a method for preserving white space in jQuery’s .val() function.
$.valHooks.textarea = {
get: function( elem ) {
return elem.value.replace( /\r?\n/g, "\r\n" );
}};
I used EchoSign for the first time today. It’s Adobe’s online electronic signature system, pretty handy.
Found this article which shows how to subscribe list members via the command line:
/usr/lib/mailman/bin/add_members -r - my_list <<-EOF >sue@foo.com >bob@bar.com >EOF
Found this article which has a handy ‘escape’ function:
// replace any non-ascii character with its hex code.
function escape($value) {
$return = '';
for($i = 0; $i < strlen($value); ++$i) {
$char = $value[$i];
$ord = ord($char);
if($char !== "'" && $char !== "\"" && $char !== '\\' && $ord >= 32 && $ord <= 126)
$return .= $char;
else
$return .= '\\x' . dechex($ord);
}
return $return;
}
Some reading to do concerning integrating Postfix/Kerberos with LDAP:

Found this article today, Execute Multiple MySQL Queries from One String in PHP. It’s a work around for processing MySQL batch queries separated by semicolons.
Today I ran the following command to see how many people accessed the ProgClub wiki over the previous 5 hours:
jj5@charity:/var/log/apache2$ grep "GET /wiki/" access.log |
grep "13/Jul/2013:0" | grep -Eo '^([0-9]{1,3}\.){3}[0-9]{1,3}' | sort | uniq | wc
Today I heard from John Resig on StackOverflow about how to clone objects using jQuery:
// Shallow copy
var newObject = jQuery.extend({}, oldObject);
// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);
Turned up this old document about HTTP Caching in Mozilla.
I had to do two things today. One was to make sure that in production all of my resources were cached. The other was to make sure that in development none of my resources were cached. I ended up with these two functions, which seem to be doing the trick to disable/enable caching:
function set_nocache() {
header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
}
function set_cache() {
header('Expires: ' . gmdate( 'D, d M Y H:i:s', time()+31536000 ) . ' GMT');
header('Cache-Control: max-age=31536000');
}
Reference: Completely disable any browser caching.
