AFAIK, I'm the only committer on the ASF's Pulse lab project. Which in a way is fine, since I'm doing a major overhaul on it this week. Improvements in the works include:
- Collecting subscriber details so people can find out what-all lists they're on;
- Speeding up the algorithm for counting recent messages by about four orders of magnitude (yes, 4!);
- Generating the intermediate XML using a DOM export rather than error-prone hand-crafted print statements;
- Breaking the web page into separate pieces by domain rather than having a single monstrous document;
- Changing the web page format to XHTML5 (with advice from Sam Ruby);
- Maybe spicing the pages up and making them more interactive with some jQuery;
- Making the graphs more meaningful, and maybe doing them in SVG with PNG as an option
Much of that is going to be happening 'behind the scenes,' as it were, and not be visible on the site. But if you want to watch the code, it's at <URL:http://svn.apache.org/repos/asf/labs/pulse/>. And when it goes live, be sure I'll blog about it.
