Today I was googling to figure out how I could minimize any application to the Ubuntu system tray.

I am very used to Outlook and I have recently migrated to Thunderbird, so I was looking for a method to minimize Thunderbird to the system tray.

I found two solutions.

The first one was New Mail Icon, which is an extension for Thunderbird. It works like a charm, putting the Thunderbird icon in the system tray. This icon changes when a new mail is received.

I also found the AllTray application. With this software you can minimaze any application you want to the Ubuntu system tray. Pretty cute!

To install it, open a terminal and type:

sudo apt-get install alltray

This week I’ve started a new XNA project and I had some troubles trying to configure the solution with Visual Studio, until I figured out how easy it was.

The point was creating a single solution with both Windows and XBOX projects on it. I also want a single shared folder for the sources.

I started creating a blank solution.

Then I added both XBOX and Windows projects to the solution.

To create a shared folder for sources I had to create a folder in the solution.

Then I added the sources contained in that solution folder in both projects as a link.

If you need to add additional files to the sources folder you must add them in the solution folder, and then add them to both projects always as a link.

And that’s all.

One of my current projects consists in building and old arcade cabinet entirely from scratch.

This would be a long process. I am planning to buy wood panels and cut them off to form the cabinet based on the blueprints I am finishing off.

I have the controls already ordered at Ultimarc, and I am currently preparing the computer I’m going to bundle inside the cabinet.

I have also a 21” CRT TV happily waiting to be dismantled and connected to the cabinet

For running roms I’m using Mame, of course, apart of some other good emulators for Sega and Nintendo game consoles.

Paired with Mame I’m using Mamewah, which is a Mame front-end that let you browse your rom list with the arcade controls, rather than with a keyboard and a mouse. It let you use other emulators as well, so we can select any rom, from any emulator we have installed, without leaving Mamewah.

In the following posts I will be explaining each step of the construction of the cabinet.

Wish me luck

This a simple tutorial about how to create a local dependecy injection within two EJBs 3.0.

The point is creating one EJB that calls a method from another local EJB with Netbeans and Glassfish.

Start Netbeans and create a new EJB project called Util and add a new session bean to it. Make it stateless and local.

@Local
public interface UtilLocal
{
    int returnInt();
}

@Stateless
public class UtilBean implements UtilLocal
{
    public int returnSomething()
    {
        return 0;
    }
}

Now create a second EJB project called Main and add a new session bean to it, like in the Util EJB. Include the Util EJB inside the Main EJB project.

@Local
public interface MainLocal
{
    int doSomeLogic();
}

@Stateless
public class MainBean implements MainLocal
{
    @EJB(beanName="UtilBean")
    UtilLocal utilEJB;

    public int doSomeLogic()
    {
        return utilEJB.returnSomething();
    }
}

Note that we use @EJB to instantiate the Util EJB object.


Simple yet effective
