.htaccess is only a file in your home folder. But it can do wonders. It can change settings on the servers and allow you to do many different things. The .htaccess file isn’t difficult to use and is really just made up of a few simple instructions in a text file. Let me note down a few situations where the .htaccess file can be used. These are requests that I get frequently and hope this article will help you get it done, all by yourselves.

For those looking forward to yet another technical blog, I have something even more attractive. This time, the article encompasses culture and tradition. The very Culture and tradition that gives Kerala the name ”God’s Own Country”. Kerala gets the name not just for it’s natural beauty, that rushes to the mind of each tourist who visits the state. Indeed Kerala is unique and special, as it has a blend of great natural beauty around its beaches, backwaters, forests, rivers and of course a mountainous belt of western ghats.
Kerala has a long tradition of religious harmony in spite of being a highly politicized region. The state where we have 100% literacy rates, where women enjoy the highest social status. Thanks to the coastline that brought in trade along with varied foreign influences in our tradition; helping in shaping our culture, and nurturing art forms like Kathakali, Kalaripayattu, Thaayambaka and Vallamkali(snake-boat race).

Hey, is spam bogging you down? Is it clogging your Inbox? Has it become a nuisance in your day to day life? Deleting them is an easy way out, but if you want to really fight spam then read on…
Wouldn’t be great if you could stop spam? To do that, it is always best to get to the root cause of a problem. In this case, spam can be stopped if you shoot a complaint to the Internet Service Provider (ISP) or the DataCentre from where this spam originated. Nowadays, most ISP’s have a “zero tolerance” policy against spammers. As per their policy, they can delete the spammers account, make them pay hefty fine or even send them to jail! Yet, we are to blame to, a majority of this spam goes unreported. Read the rest of this entry »

To roll out an IT service or business application into production, companies customize standard application packages, or go ahead and develop the entire application inhouse. In either case, applications go through a rigorous release management cycle, before it is put in to production. This is pretty much similar to the process applied to production systems, that need to be patched or updated.

To define a firewall in simple terms, one can put it to words as a - protective system that functions between your host/network and the sometimes “deadly” Internet. An effective firewall policy, prevents unauthorized use and access to your network/server.
The role of a firewall is to analyse information entering and leaving the network/server, based on an existing firewall configuration. It usually acts as a barrier for many form of attacks.
Ideally, a security strategy puts to use both hardware, and software firewalls. That said, understanding them based on a comparative approach definitely helps framing sound firewall policies.
