Zimbra: Getting Away Messages to Work With Domain Alises

While most of our mail is simply sent to “person@tcg.com”, our Zimbra server has a larger qualified domain name (let’s call it “mail.tcg.com”).  To get this to work, we completely configured up the domain “mail.tcg.com” and all the users within our…

Recovering a Slightly Corrupted Zimbra OpenLDAP Directory

Using a Wii Controller on Mythbuntu

My wife and I love our MythTV box (a great set of open source projects that allow you to make your own TiVo-like machine), so we just needed to have a front-end box for our treadmill.  But, we didn’t have an extra…

Creating an RSS feed From an iCalendar Zimbra Stream

At TCG, we have moved to using Zimbra for company-wide collaboration and are rather pleased with its mail and calendar capabilities.  Within the system we created an event calendar to hold vacations or company events, and I thought that an RSS…

Simple Date Validation and Year Completion in JavaScript

Dates in Web forms drive me crazy! On some sites, you must enter a date in a very particular format. On other sites, you must have 4 digit years, but 2 digit years on other sites. For this reason, we have decided to package…
