Gyppzy is Live Now!

ImageYES! It’s live now. We were able to release MVP (Minimum Viable Product) ¬†last week. Now it’s open for Early Adopter invitations. Of course, you can explore the site without being an early adopter. But if you are an early adopter, you guys are the first to know about our releases and promotions.

However, What is Gyppzy? Typically, when you travel around Sri Lanka it’s hard to find ‘things to do’ (activities) according to your preference in particular destination. Gyppzy can help you to find out cool activities in each district/destination. So you can plan your trip prior to your journey. Not only that you will get special discount from some places.

So, with the MVP(Current version) you can explore some activities in Kandy district. By the end of next month our target is to cover more than 1000 experiences around Sri Lanka. You also can be a part of our journey. We will announce Gyppzy ambassador program soon. So be a part of it and help your community. Keep calm and explore Gyppzy.

Getting Started with Raspberry pi

Raspi-PGB001-300x267Raspberry Pi is a tiny mini computer that will make a new¬†revolution¬†in the future world. Thanks to WSO2Con I got a free Raspberry Pi. It’s super awesome. I¬†really¬†love it. We can just plug and play with this device. But you should have some accessories to get started. Currently there are two Raspberry Pi models¬†available¬†in the market. They are Model A($25) and Model B($35). The major different of these two models are Model A has 256MB RAM, one USB port and no Ethernet port, Model B has 512MB RAM, 2 USB ports and and an Ethernet port. If you are a hacker its good to buy a Model B. I got a free Raspberry Pi Model B device at WSO2Con.

Setting up LDAP user store with Apache Directory Studio

For an example a telephone directory is a set of subscribers with address and telephone numbers. An LDAP directory can be distributed among many servers on a net work.

Execute Commands After You Exit From a Shell Prompt

Most of the time you may have to login to a remote server via a SSH and multiple commands need to execute in the same time. If you can not open multiple shell prompt tabs it is not posible to run them in the same time. So if you get exit from the command prompt the excution get killed. So better thing to do is run the excution in background. So Linux has a good option for this. Its nohup command.
