- QQ.com, Taobao.com, Baidu.com. Given that the Chinese do not pioneer web platforms, I don't see why they'd do this.
From what I've seen and heard, this isn't true. Taobao in particular seems to be running on a pretty cool stack, and has contributed a lot with OpenResty, which is nginx with modules, LuaJIT and some goodness, backed by Redis, Memcached, MySQL and/or Postgres (inside nginx' event model).
Very unlikely; Amazon's backend is basically Perl talking to an SoA via an internal service definition language. A change to server-side JS would require a re-write of almost everything (which isn't unprecedented; the migration from a single giant C++ binary to the Perl system 10-odd years ago was such a rewrite).
So, yeah, no technical limitation, but explaining to Jeff that you've spent a year retooling the build system to support node.js but not actually shipped any features yet might lead to limitations of another sort :-)
Indeed, and this is why I agree that it's pretty unlikely :).
During my stint at Amazon we barely had time to build the infrastructure we absolutely needed to launch features on the artificial deadlines imposed from somewhere in the stratosphere. How anyone had time to work on paying off technical debt or building new infrastructure is beyond me.
are you talking about the top-10 websites? let's take them one by one:
- Google. I don't think so, it's not even one of their major server-side languages now.
- Facebook. Likewise.
- YouTube. See Google.
- Yahoo!. I don't know anything about their server-side
- QQ.com, Taobao.com, Baidu.com. Given that the Chinese do not pioneer web platforms, I don't see why they'd do this.
- Windows Live. I know MS "likes" JavaScript, putting it in Windows and all, but it's not one of their major languages. It's not even their own :P
- Wikipedia. Would require a switch from MediaWiki or rewrite. While I'd very much like to see PHP replaced, it's currently doing it's job. I have a feeling the language does not matter much, MediaWiki itself is not very complicated.
- Amazon.com. Don't know.
Do you seriously see 5 or more of these turning to server-side JS?
