Delete unuse Java Console in Firefox

2011-01-17T23:51:00.001+08:00

Every-time when you update the Java client, a new version of Java Console add-on will install in Firefox. However the old version of Java Console are not uninstall automatically. Moreover, uninstall the old version of Java installation will not remove the add-on automatically.

The most annoying thing is the Uninstall button in Firefox Add-ons dialog was dim out. Finally, I found the solution from the following discussion:

http://www.overclock.net/networking-security/690003-how-remove-java-console-firefox.html

The steps is simple. To delete the old Java Console add-ons, run Firefox as Administrator.

Mono 2.6.7 on CentOS 5.5

2010-08-23T14:14:00.000+08:00

I successfully install Mono 2.6.7 without using the source. There is a Mono repoistory available on Mono web site, so using the Package Manager is much easier.

Launch the Package Manager, select Edit->Repoistories; Choose Add.
Give the Repoistory name and description "Mono", in Location input the url:
http://ftp.novell.com/pub/mono/download-stable/RHEL_5/

Select Advance and enable GPG key:
http://ftp.novell.com/pub/mono/download-stable/RHEL_5/repodata/repomd.xml.key

That's it! Now the Package Manager will refresh, so to search Mono and the latest Mono will be there.

Microsoft game console name copied Sony Playstation

2010-08-20T21:20:00.000+08:00

From this post, it seems the successor of Xbox 360 should have somethine relate to triangle.

http://forum.unity3d.com/viewtopic.php?t=61839

If the see the picture of Playstation controller, all generation of Playstation controller has button "X", square, circle, and triangle.

http://commons.wikimedia.org/wiki/File:PlayStation_Controller_transparent.png

Microsoft name is first game console with the button "X", and the , so it name XBOX.
The successor of XBOX took the circle button, since circle is 360 degree, so the current Microsoft console is Xbox 360.

jPackage ant dependency fix

2010-06-22T11:26:00.002+08:00

I need Ant package to try the Liferay theme development, I found the jPackage has most Java related rpm, install jPackage is easy.

http://www.jpackage.org/yum.php

When add Ant, I got dependency error
/usr/bin/rebuild-security-providers is needed by package java-1.4.2-gcj-compat-1.4.2.0-40jpp.115.i386

After search over Google, I found the solution here:
http://www.cpurigs.com/forums/showthread.php?t=4770

1. Remove jpackage-utils and tell it to ignore dependencies: rpm -e jpackage-utils --nodeps
2. Install the version offered through the standard repos: yum install jpackage-utils
3. Update everything else: yum update

Now I can install Ant from jPackage.

Enable AHCI on Vista

2010-05-09T13:36:00.002+08:00

I swapped a Seagate 1.5T 7200.11 in my home computer, and mount it in a new mobile rack as I plan to mount different hard drive for testing.

I just figure out how to enable hotplug and AHCI:

http://www.itwriting.com/blog/288-enabling-ahci-on-vista.html

Vista works fine with AHCI, and you will not run into problems with a new install. However, if you change this setting underneath an installed Vista, it will likely blue-screen on you. The trick is to edit the registry setting here:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
Edit the Start key and change its value to 0. Then shut down, change the BIOS to AHCI, and reboot. All going well, Vista will detect the change, install new drivers, ask you to reboot once more, and it’s done.

Remove Network Connection 1, 2, 3 in Windows

2010-05-07T18:53:00.002+08:00

Found a way to remove unneeded network connection:
http://www.pcreview.co.uk/forums/thread-102477.php

Go to Start/Run/CMD. At the command prompt, type the following commands and
press enter after each line:

set DEVMGR_SHOW_DETAILS=1
set DEVMGR_SHOW_NONPRESENT_DEVICES=1
start devmgmt.msc

Click the View menu and select Show hidden devices. Right click the device
you want to delete and click Properties. Click the Details tab.

Select Device Instance ID. The value of Device Instance ID is the hardware
key of the device.

For example, if you see the value is Root\Image\0000, the full hardware key
is: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\Image\0000

Then go to Start/Run/Regedit and navigate to the key. The data of the
Driver value is the software key of the device. Delete both the hardware
key and software key.

Added note: Network connections are listed here: 1, 2, 3, 4.....etc:
Start/Run/Regedit

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{}

Installing modules in Drupal

2010-02-02T15:13:00.000+08:00

Today I learned how to install Views, CCK, Whizzywig in Drupal 6.15. Simply download the module zip and unzip into site/all/modules. Very straight forward.

Now reading the TopNotchThemes Quickstart Guide, this is a great guide to learn how to customize Drupal site, much better than Drupal's online documentation.

While trying the CCK to add fields, there is no "Image" file type. The file type should be "File" and widget type should be "Image".
