Just came across this little gem while trying to look for a cloud-based tool to create UML diagrams. Pretty darn cool!

You can create a Sequence diagram just by typing the relationships between the entities and it gets rendered automatically.

Check them out.

If you’re looking for a quick way to start hosting your PHP5 applications, here’s an EC2 AMI image I’ve created to help make it easier.

It is a x64 Ubuntu Oneiric EBS AMI Image running a LEMP (Linux, Nginx, MySQL, PHP) stack which is suitable for those who wants to make use of Amazon’s free-tier micro instances.

Its currently only available for the AP-Southeast region (Singapore).

Tip: Remember to create a swap partition.

Update: Forgot to list down the necessary authentication information.

- Login with the username ubuntu and your key when you start it.
- MySQL root default password is ubuntu1024. Remember to change it!

Just got back from a basic introduction course to Ardunio over at HackerspaceSG.

I’ve always wanted to try out the Arduino and when this class appeared in the HackerspaceSG mailing list, I knew I had to jump on it.

Thanks Dave Appleton for conducting the class.

Maybe I should pickup a Starter Kit now.
