Yahoo Finance recently launched new super cool interative draggable charts. I wanted to blog about it for quite some time but anyways its never too late ..
Yahoo finance has been number 1 finance portal for past many years. It takes less work to get to top than to stay at top. Number 2 position has always has number 1 to look forward to but number 1 has to be always innovative and competitive to beat the rest of the crowd. Though ppl often comment “Yahoo finance look the same for past couple of years” , but they need to know that we were always making our base stronger and stronger for better user experience and launch the following major projects and more
Streaming quotes : Today if you look at http://finance.yahoo.com/q?s=yhoo , you wil find the quotes updating automatically without refreshing the page. Marketwatch has this feature for quite some time and ppl had a question why cant Yahoo finance do it. Well we were planing it much before them but we have millions of hits each day and thousands of hits per minute . If we had to go via simple ajax (Pull)method then we would have done it long time back , but with this much of traffic it was a big engineering challenge. If we had gone via pull method where the application tells the server that now i want the update then with the amout of traffic we get, we would have blown away the inventory of servers being used. We took some time but solved this challenging problem smartly using minimum hardware.
