Google Similar Image Search Firefox Addon

I found it annoying that I could not search for similar images directly from the browser.

I figured this should not be a hard thing to do, so I decided to write a firefox addon which will allow you to right click on an image and search for similar image (the technical term is "reverse image search").

So, here it is : Google Image Search.

PS: Later many such addons came out. Most of them better than mine :)

Airtel broadband DNS sucks and how to fix it

I have been using for Airtel broadband sometime now, I find their DNS annoying if not unusable. Every now and then DNS server goes unresponsive which slows down internet for me.  After a while, well, I decided to take things into my own hands.

The solution is simple - use a better DNS server.  One way of doing this is to change the network settings in your computer to use a static DNS.  In linux, you edit /etc/resolv.conf. In windows this is done by editing Interface properties.

But this method did not suit me because there are multiple devices connected in my home network and I will have to change all of them. Also, devices come and go in our network (We have BYOD!).  The way out is to change your modem settings so that your modem relays a different DNS than what Airtel gives you.

I have always liked Google public DNS -- I think because they have super simple IP addresses ;).  I used it as my DNS Server.

I have a Binatone DT845W modem. So the steps below are for that modem.
Connect your modem in your browser. Usually modem IP is, so just point your browser to that address, provide your admin username and password.

Go to "Interface Setup" -> "LAN", there you can find a section called "DNS".  Change DNS relay to "Use user discovered DNS". Fill in your favorite DNS server IPs, save the settings and your done.

Welcome to a better Internet :)
