      It's Java... The only closed part you would need is the Java class library from SUN, which has freely available source that you can modify for your own internal use. The rest you can do with jikes and tomcat. Tomcat is used in all the big J2EE servers... IBM uses it in WebSphere, for example. Tomcat is the reference implementation of JSP/Servlets. You may need to use JBoss, Geronimo, or OpenEJB with SalesForce because I'm pretty sure they use Enterprise JavaBeans.

      My bet on a fully open system would be with Python/ZOPE. It's missing a few things, but it's very eligant.

      Just to nitpick

      LAMP is php (and linux, apache, mysql) and last I checked Slashdot used mod_perl...

      but it is still open source.

      Hmmm, this post is modded up as informative, when it should really be modded down as misinformative (if only there were such an option).

      Somebody please mod up one of the child posts that correct the parent by pointing out that the "P" in LAMP represents Perl, Python, or PHP. Please DON'T give me the karma, give it to those still posting at 1. Thanks.

  6. Maypole! by Anonymous Coward · · Score: 5, Informative

    Maypole is a Perl framework for MVC-oriented web applications, similar to Jakarta's Struts. Maypole is designed to minimize coding requirements for creating simple web interfaces to databases, while remaining flexible enough to support enterprise web applications.

  7. layers -- kind a like the onion by yintercept · · Score: 3, Informative

    The web is really a mixed bag that allows a mix of open standards, and proprietary software. To claim it is all open source is misleading. It is a dynamic network that allows development on multiple layers.

    The most important aspect of the web is that the interface of the different layers were well defined and exposed...not that each line of code in the different layers is exposed.

    Thats only posts, it doesnt take into account comments (which is probably most of the traffic) userpics, etc.
    Your assumption would be correct if it was 1 select for each page view, but since there are about 4-5 just for 1 page view (userpic, friends, info, etc) then that number is misleading.. Fortunally most of that static content is memcached and not hitting the DB's.
