Zappos.com is an e-commerce retailer that has successfully built a strong online brand and shown impressive revenue growth since its founding. The gross revenue numbers basically speak for themselves: 2000 $1.6M, 2001 $8.6M, 2002 $32M, 2003 $70M, 2004 $184M, and 2005 $370M.

Microsoft goes Open Source

July 22nd, 2009 Vinay No comments

Sounds very strange that the company which has been against the open source and dismissed it as a non serious player has taken the route to open source. No they are not giving away all the windows code to open source (some of you would love to have it) but they have submitted 20,000 lines of code to the Linux kernel community for inclusion in the Linux tree.

The three device drivers are being released under the GPLv2 license, which is the Linux community’s preferred license.

This comes on the heel of making SilverLight open source. Read Silver Light goes Open Source

John Chow vs Google

July 21st, 2009 Vinay No comments

Many years ago John Chow started getting steam as a blogger and told Google to goto hell. John sold paid links, paid reviews, and did massive amounts of reciprocal link exchanges to gain tons of back links. All of which fall under the penalty of death under google’s kingdom

John was given the death penalty and completely removed from the Google Index. Many people wrote about this and how Google was owning John and he was done for.

But with banned by google , a strange thing happened. His popularity and brand grew. Now it was the success story of how you really don’t really need Google to succeed on the internet.

Search traffic for john chow was growing but nobody could find him on Google. What people were finding was infringing sites like johncow or notjohnchow who were only getting traffic because they were ranking for John’s name.

Always being creative and realizing that Google penalizes the domain, but not the link, John registered Johnchow.ca and redirected GoogleBot to that domain. Within days Johnchow.ca started ranking for all the phrases that johnchow.com used to. But google did not liked it and within couple days Johnchow.ca was penalized as bad as JohnChow.com.

But looks like JohnChow is back in google search and that too at a very good rank !!

What is new in HTML 5

July 16th, 2009 Vinay No comments

The version of html which we are currently using is HTML and it has not seen a major update in last 10 years although there has been so much development in UI in terms of technology and browsers.

W3C is working on next major release of HTML , keeping in tunes with the times and has released a draft version. HTML 5 defines the fifth major revision of the core language of the World Wide Web, HTML

The technical difference can be read from here HTML 5

One of the most important features which I liked about HTML5 was its database specification . This lets a web application create and use a local database, which means it can work without an internet connection, and even more importantly, it’s way faster than before. HTML5 is supposed to be disruptive and is already being used in Google.

Google has demoed the new version of gmail which is in HTML5 . Click here to see the demo

Firefox 3.5 supports HTML 5 audio and video with Ogg Theora

HTMl5 would bring much more power to the web and to the developers who definitely would bring some innovative applications

Twitter has been written in which programming language ?

July 14th, 2009 Vinay 11 comments

If somebody would have asked me few days back this question , I would not have known the answer. But I always wanted to find about the technology and tricks used at high performance sites like  twitter , facebook and ebay.

During discussions with one of the colleagues, I came to know that core(the back end services) of  twitter has been written in Scala. And that set me going . Twitter had really high load going to 5000 tweets per minutes at times.

Update : Thanks to the comments posted by users, especially Dave who have informed that the front end has been written in Ruby on Rails.

I really wanted to find out more about Scala and learn about it.

What is Scala ?

Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages, enabling Java and other programmers to be more productive. Code sizes are typically reduced by a factor of two to three when compared to an equivalent Java application.

Many top-notch programmers and industry leaders have already been captivated by Scala. James Strachan even says that scala is the long term replacement of java and javac.

Find more about scala here

I will be covering more about Scala in next post and how is it more efficient over Java.
