OpenID for CodeIgniter made easy – All about it
Oct 21st

Luckily RPXNow stepped in and provided me a hand in authenticate people and handling the magic works. No one likes to reinvent the wheel after all, and this is a PRETTY HARD wheel to deal with…

This is a simple, plug it in, it runs, guide. It is still highly recommended that you try and run FPDF successfully without Codeigniter first. So that you know how to actively runs it or your web server supports it.

Jquery Pagination System
Oct 13th
When you think of a pagination system, you would think about some messy PHP codes to generate each and every page. So subsequently, for an user who wants to browse through your pages, they will do a lot of calls to your PHP file and by that do a lot of calls to your database (a bad thing!). So, we want to load all the data from PHP/MySQL ONCE and have the pagination taken care of by Jquery.
Copy & Paste all of this code into a html file. Make sure you are online so that the browser can retrieve the More >

Huddle Review
Oct 11th
Huddle is my choice for web collaboration system as well as Project Management software.
I was in search of a free, powerful, easy to use, social collaboration software. And Huddle is my final stop, for now.
Huddle allows team members to share documents, and conduct various projects in a multi-agent, multi-user, central, online, collaborative environment. Huddle separates itself from basecamphq by offering a free for all time plan. Of course basecamphq was once offering a free package, but not anymore. Huddle was designed with internet collaboration totally in mind. The project manager can add and assign tasks to each of the team members More >
