Intel CPU Core Duo vs Core2 Duo

Intel CPU Core Duo is the very first generation of intel multicore architecture.
Therefore, there are no x64 support in Intel Core Duo.

Intel CPU Core2 Duo, however, has the capability of supporting x64 operation system.

The very benefits of x64 operation system is that you are able to allow more than 4 GB main memory in operation system. In contrast to x64, x86 windows can only allow the usage of no more than 3 GB main memory. Thats all about the operation system design. In Linux system, you can also allow more than 4 GB main memory with PAE kernel (physical adress extention)

Eclipse/PDT (PHP Developer Tool)

* system support: Linux/Windows
* Plugins: CVS, Subversiv with Connector (for SVN)
* Debugger: Xdebug (Should be compiled with phpize, you need php-devel package)

Solve mouse stuck issue linux VM guest

[Environment]

Opensuse 11.3 as Linux VM guest operating system
vmware server 2.02 as vmhost in window7 x64bit
vmware player 3.12 as vmhost in window7 x86

[Problem]

The left mouse buttons “stacks” in a “pressed” state when I keep it
pressed for more that a moment! So, when I move a window for example,
when I physically release the button, the X does not release it! It
“thinks” that I keep press it.

The mouse left button is locked but I can unlock it with a single right
click or escape with keyboard.

The mouse click and drag . . . gets stuck in stuck state . . .
The mouse click was going dead from time to time as well.

[Solution/Workarround]

** Edit as root user the /lib/udev/rules.d/69-xorg-vmmouse.rules file. **

/*From*/

ACTION==”add|change”, ENV==”?*”, ATTRS==”i8042 AUX port”,
PROGRAM=”/usr/bin/vmmouse_detect”, ENV{ID_INPUT.tags}=”vmmouse”

/*To*/

ACTION==”add|change”, ENV==”?”, ATTRS==”i8042 AUX port”,
KERNEL==”event[0-9]”, PROGRAM=”/usr/bin/vmmouse_detect”,
ENV{ID_INPUT.tags}=”vmmouse”

/*Or From*/

ACTION==”add|change”, ENV{ID_INPUT_MOUSE}==”?*”, ATTRS==”i8042 AUX port”,
PROGRAM=”/usr/bin/vmmouse_detect”, ENV{ID_INPUT.tags}=”vmmouse”

/*To*/

ACTION==”add|change”, ENV{ID_INPUT_MOUSE}==”?”, ATTRS==”i8042 AUX port”,
KERNEL==”event[0-9]”, PROGRAM=”/usr/bin/vmmouse_detect”, ENV{ID_INPUT.tags}=”vmmouse”

[Note]
Keep in mind that the * charator in both case in ENV parts should be delete, and add KERNEL==”even[0-9]” part in the rule.
