This is memo.
We can see message in log.log, when protocol send/receive NekoMessage  to/from other protocols. However, if some message extends NekoMessage then the send/receive log doesn't print into log. Because, the message is extended class from NekoMessage. The log mechanisms are working as (MAYBE) calling NekoMessage.getSource().
HOW TO PRINT LOG INTO "log.log" One of the solutions is to call This meaning is ....
#####BEGIN EXAMPLE###### (This is not completed code...... You need implements more for implementing protocols. ) Logger logger = new NekoLogger.getLogger(YourClassName.class.getName()); SenderInterface sender;
public void send(NekoMessage m) {"ANY MESSAGE  " + m.getSource()); 
public void setSender(SenderInterface sender) { this.sender = sender;
} ###########END EXAMPLE###############

Player/Stage :: Mac OSX Leopard

This is just memo.
I write memo for Player/stage on Mac OSX Leopard.

At first, we have to install Player/Stage by MacPort.
sudo port install playerstage-stage
sudo port install playerstage-player

Maybe, when you execute the player on your OSX then you will see the error for rgb.txt.
If you see this error then you need to make the symbolic link from "/usr/X11/share/X11/rgb.txt".

Well, MacPort provides Player/Stage version 2.0.3.
But, latest version of Player/Stage is version 3.0.1.
I downloaded version 3.0.1.
However, it didn't work because of version.
I try to use on version 2.0.3, then I can use player/stage.

Today, MS Office 2004 for Mac OSX got update....
I find a problem about update.
The update system is so smart because we cannot update all version at same time.
Usually, I update just a time when I remind about it.

However, today I try to push update after updating the office.
Then I could see more update packages.
Finally, I update more than 4 times.

It is not convenient to use.....

[ Ubuntu ] printer set up

I set up the new printer on my Ubuntu Linux machine.
I had problem about the password.

The printer management system asked my password before finishing to set-up it. However, the system kicked my password. I suspected it. Then I changed password from command prompt. And try it again. However. the system also kicked my new password.
I ask to prof. google then many of person had same problems. The solution is just easy. We try it with as admin users. However, the system need the user that the user have to have lpadmin groups.
So, you can add your account to /etc/group as lpadmin.

#sudo vi /etc/group
and add your account name to the end of lpadmin
lpadmin:x:109:your_user_name, your_username2(if your pc has more than 2 administrators)
