Calico QR- code System

Calico is a Sri Lankan company  that manufacture Cords and tapes. Their main customers are Adidas and Nike, company’s manufacturing plant is located at Negombo,  Sri Lannka. Recently they approached us to develop a QR-Code generating  software for their packing section. Which they can put it on their boxes  and access the QR-code using their mobile to get entire details  about the package eg: contents, current location and invoice.

We were able to complete this project successfully, within few weeks. To accomplish this task we used technologies such as PHP, Mysql, HTML, CSS and Javascript. For Qr-code generating process, i used a third party library called phpqrcode developed by Alexandre Assouad, you can check his librarys at github-account.

Here is the code snippet for adding phpqrcode library.

Hope this Helps. 🙂

lolcorps.com

Lolcorps.com is a entertainment website that display funny images, animations with memos. Actually i never planned for this website. This time i was working in a telecommunication company in Sri Lanka, here i used to write scripts for servers. so i was doing some research on servers and testing some of my automated scripts, eventually i ran that script on one of the popular entertainment website and download all their resources from their server with in 3 hours. I downloaded 18000 image assets from that entertainment website in 3hours, that’s  a huge amount of resources. Now i thought of putting this resource in a useful way.

So now i wrote a simple algorithm to sort this images in to categories and get the image name, strip all the unwanted characters and use it as a database field. Now i have the resources and database ready, i then downloaded a HTML theme from themeforest.com and developed a website  using codeigniter with in a month and put it live. It is still live at the time of writing this article. Please visit : http://www.lolcorps.com/home/most_recent
