Last night I upgraded both of my blogs to Wordpress 2.8 and ran into a couple problems. The redirection plugin caused some problems with wp-db.php so I had to disable that to get the site back up if you upgrade redirection prior to upgrading you won’t have that problem.

The other problem I ran into was that I would be presented with a page saying “Database Upgrade Required”, after upgrading it would bring me back to the same page. The problem ended up being the wp-content/object-cache.php file, moving that out fixed the problem. However because the page was still cached in memcache moving the file back raised the same issues. The faster fix is to restart memcache all together to clear the cache.

Long ago I switched from using any sort of mail client to using the webmail interface of Gmail/Google Apps. This switch was really fueled by my increased usage of the interface after being hired by Google. I won’t go on and on about using the web interface, but sometimes it is nice to know how many actual emails are in your account. Google mail only shows you the number of threaded emails, not each individual response. If I look in “All Mail” for my manis@digital39.com account I see “1 – 100 of 21758″, which represents the number of email threads, the actual number of responses is 56578. FYI, this requires that you enable IMAP support for the account.

$ imap_count.py manis@digital39.com
Password for manis@digital39.com: *****
56578 messages in account manis@digital39.com

Expand the code below and copy it to a file on your system. It takes one argument, and that argument is a comma separated list of email addresses.
