The panel encountered a problem while loading Gnome desktop applet

The panel encountered a problem while loading Gnome desktop applet

Last time while I come to desktop after starting my Ubuntu 10.10 (Maverick Meerkat) machine, a message appear infront-of me. A dialogue box say:

The panel encountered a problem while loading "OAFHD:GNOME_NotificationAreaApplet".

Do you want to delete the applet from your configuration?

I click on Dont Delete. I restart my computer and everything goes fine. No any warning message shows its ugly face anymore. I searched google if there are anybody facing this kind of problem. I found many result. I understand that this problem occurs when applets start on panels. I add 20 applet on top panel. It is a heavy panel to load quickly. Dont blame me for this practice. I am a Ubuntu guy man. And I leave windows for greed of this kind of customisation ability. But what about the problem?

I found that when you see this kind of crash report, please restart of simply logout and login again. Wish to solve the problem.

You can try some more way to solve it.

• Create a new user and use this account.
• Reinstall gnome-applets and gnome-applets-data from synaptic package manager.
• Logout and login again
• Update/upgrade system. (System should fully patched and updated)

The Latest PS4 Firmware Update Is Causing Some Serious Problem

The Latest PS4 Firmware Update Is Causing Some Serious Problem

Last week, Sony released a major update for the PlayStation 4. This new firmware update offers a variety of highly-demanded features, including support for an external hard drive, modifications to PlayStation VR, and custom wallpapers just to name a few. However, many PS4 owners have reported several issues with update 4.50.

According to several PS4 users, on the official PlayStation Forums, update 4.50 is causing some annoying WiFi issues. Gamers who�s wireless internet connection worked fine prior to the update are now reporting connectivity issues with their console, resulting in major lag and issues joining online matches.

To combat these issues. here are a few do it yourself solutions:

• Switch your wireless router�s signal support from B/G/N to just B/G. This workaround requires accessing your wireless router�s internal settings by typing the IP address of your wireless router directly into your web browser and entering the username and password.

• Some users are reporting success after disabling their router�s wireless password or switching security from WPA2 to something different. Fair warning, though the WiFi issues are not worth compromising your wireless security.

• If none of the above work, then connect your PlayStation 4 physically through a  network cable.

Currently, Sony has not commented on the update 4.50 WiFi controversy. But hopefully, they are working hard on making a patch to address the issue.

The JAVA path problem of the MATLAB installation

The JAVA path problem of the MATLAB installation

The below message shows an error, suggesting that MATLAB cannot find Java library.

Warning: Unable to find Java library: /usr/local/java/jdk1.7.0_17/jre/lib/rt.jar/lib/i386/libjava.so
Please check if you have a MATLAB_JAVA environment variable.
Note that MATLAB requires Java version 1.4 or higher.
Warning: Disabling Java support
 The solution is to direct the MATLAB java environment path to the folder that comes together with the MATLAB installation, instead of the one installed in the system. Here is how to do it. 

yslin@yslin-Ubu2G:~/MATLAB$ export MATLAB_JAVA=/home/yslin/MATLAB/R2011a_Student/sys/java/jre/glnx86/jre
yslin@yslin-Ubu2G:~/MATLAB$ echo MATLAB_JAVA
 Firstly, you need to find where your MATLAB installation is. I installed it on my home folder, rather than in the system (i.e., under the root "/"), so I located it under the folder, ~/MATLAB/R2011a_Student/sys/java/jre/glnx86/jre. The second step just to check, using "echo", if the environment variable, MATLAB_JAVA, has been exported successfully.
