IE and PHP sessions
I ran into a strange encounter after testing out a session based login system through an IE browser. I had been working mostly with it in other browsers, mainly Firefox where it was working fine.
Wordpress 2.8.6 Spell Check Languages
When trying to add norwegian as the default language for one of my wordpress sites, I had problems finding documentation for where the language list actually is located. Tracking it down myself become a long task as well. Here is how you can edit the languages for your wordpress system.
Reset MySQL Root Password
If you have mysql- or root user shell access to the linux host where your mysql is running, you can reset the password like this:
Linux hosts file
Just a quick reminder to self for later – I had almost forgotten – on how to set up the hosts file. It’s important for having a fully qualified hostname for many linux network services to work.
IdleGuard
Some MMO games have been criticized for having up to 5 hour – or more – queues before you can actually enter the game and play. This inspired me to create a mini-program that might help you with this by reducing the amount of times you need to actually log in. Any software that kicks you for being idle might have a use for this little program.
Column count in SQL
At rare occasions you might need to know the number of columns in a database table. This isn’t necessarily as easy as counting rows.
String encryption in PHP
I’ve been working on 2 PHP functions that can be used to encrypt and decrypt alphanumeric strings between web pages. This is used for e.g. Captcha codes that you can generate yourself and encrypt / decrypt with these functions.
Alphanumeric Captcha values in PHP
In my former post I wrote about making Captcha solutions without the need for database storage. I wrote an example exclusively based on pure numeric values. I’d like to illustrate how you could create alphanumeric Captcha values instead of numeric ones, as this might be of interest for someone who would like a more fully fledged solution.
Your own numeric Captcha in PHP
The purpose with a Captcha user control is to give the user a challenge that a computer normally can’t resolve. In most cases this means an image with random letters and numbers on it. This is rather easy to set up without any need for a database, that many use as a solution to handle the encrypted messaging that has to happen between part1 and part2 in a Captcha utility.
