Bugs, Specs and new Sites

Moved to a new website, machdb.org Please update your bookmarks. I hope the URL change will make it into the Feb issue of LOGIN. Either way, I'll set up redirects at the old site to get people here. I also moved the blog, to be more central. When I get some time I'll make a new wiki on this domain as well.

Bugs!

Fixed an XML parsing bug in collect.php, thanks to the quick eyes of Josh, Steve and Stephen.

Found a big bug in my spec thanks to Chris. From my response:

"So I found out why your disk data showing a max of 2TB. See...this is where seeing it run in other environments teaches me the right way to do things. ;) Apparently I had some bad math when I calculated what MySQL's int(11) datatype could do. So I guess I've either got to modify the MySQL tables to be BigInt or change the spec to start with MB. With BigInt and KB, the limit is 9,223,372,036,854,775,807 KB, or 8,192 exabytes. Yep, I said exabytes. But that makes the DB bigger. With int(11) and MB, the limit is 2,048 terabytes. Thoughts? I'll noodle on this tomorrow and run it by a DBA buddy and get his feedback as well. Until then, sit tight. I will have this resolved in the next day or three."

I updated the XML spec just now to describe the limitation, so as not to confuse others.

Chris has also sent me a patch to include a unified cache in the CPU information, which will go into the next release next week. I'd like to get this out before Xmas, since I won't be around for a bit afterwards.

These bug reports are great everybody, keep em coming. :)
