What web programming language does Yahoo use for Answers? What does google use for gmail?? PHP? NO?

Question

I would like to know what yahoo writes their scripts in? And what in the world does google use, they have some odd looking query string in the URL ive never seen before?

Answer 1

Nobody can tell unless they work for the respective companies themselves. I say this because one can configure a web server to process .asp files as PHP code instead. It's common practice to do such things nowadays in order to foil potential script kiddies (juvenile crackers). As for query strings, it essentially just holds data for the application to process. We can only infer from the subtle hints and the more obvious ones that exist on the topmost presentation layer (in accordance with the MVC pattern).

For a start, I'm sure GMail uses Asynchronous Javascript And XML (AJAX). This allows it to transparently display dynamic data without refreshing the entire page. Google's search engine itself is based on C/C++ ... if I'm not mistaken. You can read their research papers on their website regarding their PageRank technology (it claims certain parts are in C/C++). I would think that GMail would be using PHP or Java .. but more likely than not, it would be PHP because it's faster to develop in.

It's hard to tell really ... we could send them an email to ask. But it's a very interesting question which I would like to know the answer to too.

Answer 2

It could be a number of them

> Python
> Ruby

I believe GMail uses Ruby and AJAX

Answer 3

Yahoo uses Ruby on Rails. I don't know about GMail but it does use AJAX on the client side....and what do you mean, "odd looking"?

Answer 4

google uses a number of things, probably the most used being python. im not sure what they use for dynamic content.

edit: google uses javascript and xml (aka ajax) for some dynamic content.
