Twelve Tile Puzzle Published

I finally completed my port of my M12 Java applet to Android. Since I added some additional puzzle modes I decided to name it "Twelve Tile Puzzle". I created a small page for it where you can see a screenshot.

Sendmail And Fully Qualified Domain Names

Recently I attempted to get sendmail to work between two machines in my internal test network. Since it's my own small network I tend to use short unqualified hostnames such as "grey" or "white". As you may know this presents certain challenges when working with sendmail since sendmail prefers FQDNs (fully qualified domain names). In this blog entry I'll talk about what those challenges are and what I think is the most straight forward way to get sendmail to work in such a network.

Red Hat Certification

Recently I took one of Red Hat's certification exam which resulted in my becoming RHCT certified. Although there isn't much I can say about t the exam due to the non-disclosure agreement I signed what I can say, which you can find elsewhere, is that it's a challenging exam. Since time is limited it's important to distinguish between things that are important and things that aren't.

I'll probably try to upgrade to RHCE in April.

Orientation In Android

Recently I've been exploring the Android operating system. I was sufficiently curious to purchase an ADP1 (an android based developer phone from Google). I think I've done enough research to begin porting my M12 puzzle. I thought I'd share some of the things I've learned along the way starting with the way orientation works.
