Just came across the Google code University, and find the materials there are very useful to refresh the distance memory of "Programming Lectures" had in University years years ago ... and something new too

JDownloader

File site such as Megaupload, hotfile etc are great to share big files but is a pain to download for free account users as they impose certain restrictions and limitations to download operations.

Today, I found this little Java utility that can ease the pain. The program is called JDownloader, which is a download manager which automates the process for you. All you need is provide a link to it, and it will take care the rest. It can even monitor your clipboard for links your copied. Since it is written in Java, you can run it on any platforms.

Select my Java

There are many varients of Java available on Ubuntu. There are OpenJDK and Sun's own JDK. By default, Ubuntu would use the open source one which is OpenJDK. Although it works, it isn't working as well as Sun's own. After a bit of research I found this little command that would save the default Java withe ease

update-alternatives --config java

This command would show you available varients of the command configuring, and let you choose the one you desired.
