Simple instructions for creating Retina favicon:

Create a 16×16 PNG-24 for your low-res icon

Create a 32×32 PNG-24 for your high-res icon

Head over to http://convertico.org/Multi_Image_to_one_icon/ and upload those two icons together to create a dual-resource ico file which you rename to favicon.ico.

Upload that favicon.ico in the root of your webroot.

For some reason the meta tag <link rel=”icon” href=”favicon.ico”> seems to prevent the high-res version from working so I temporarily removed it. If you know the correct meta tag to be using for retina please let me know.

Here is what the difference looks like:

Here is a little irssi script that will help prevent you entering your passwords into IRSSI

Click here to download the script: passfail.pl

Instructions are inside the file and below:

[perl]
use strict;
use Digest::MD5 qw(md5 md5_hex md5_base64);
use vars qw($VERSION %IRSSI);

#——————————————————————————
# passfail.pl – Help prevent you entering your passwords into IRC by mistake
#
# Copyright (C) 2010 Christopher Carey
# http://chriscarey.com
#
#——————————————————————————
# INSTALL:
#
# Stick the script passfail.pl into your .irssi/scripts/ directory.
# Symlink it into the autorun directory so it will run every time the
# application starts.
#
# cp passfail.pl .irssi/scripts/
# cd .irssi/scripts/
# ln -s passfail.pl autorun/
#
#——————————————————————————
# USAGE:
#
# Passfail has three basic commands: add, remove, show, and clearall.
#
# /passfail add <password>
#
# The previous command will add the password into the list of protected words.
# That password, if entered in the chat window, will not be sent to channel.
#
# /passfail remove <password>
#
# The previous command will remove the password from the list of protected words.
# If you type the password, it will be sent to channel.
#
# /passfail show
#
# The previous command will show the saved password hashes
#
# /passfail clearall
#
# The previous command will clear the list of protected words (start over).
#
#——————————————————————————
#
# TESTING:
#
# Test and configure on the (status) window, and not in a channel with users in it!
#
#——————————————————————————
#
# OTHER NOTES:
#
# You can manually load or unload the script with the following commands:
#
# /script load passfail.pl
# /script unload passfail
#
