Jupiter: Take Advantage Of Asus Super Hybrid Engine (SHE) In Linux [Ubuntu .deb]

fonte

SHE (Super Hybrid Engine) is a technology created through the redesigning of hardware, software and BIOS and can bring an up to 53% longer battery life for the Asus Netbooks. In addition, the Super Hybrid Engine automatically manages and regulates power distribution based on usage requirements.


To be able to use the Super Hybrid Engine in Linux, you need an application (applet) such as Jupiter (along with jupiter-support-eee - this is required for Super Hybrid Engine support) which was designed for Eeebuntu, but works on other Linux distributions too.

But Jupiter is not just for the Super Hybrid Engine equipped netbooks. In fact Jupiter works with every laptop, desktop, or netbook computer regardless of brand. It can switch between maximum and high performance and power saving mode, change the resolution and orientation, enable or disable the bluetooth, touchpad, WiFi and so on.


Overall, Jupiter is a great application for any netbook / laptop and I strongly recommend it. I've used it on my netbook for a while and it does make a difference!


Note: I've found a small bug: when switching performance modes, don't go from the highest profile to the lowest, but instead go from Power Saver to High Performance and only then to Maximum Performance (and the other way around) or else Jupiter won't work until you restart the computer.


Download Jupiter .deb and .rpm packages | Remember to also download and install jupiter-support-eee if you own an Asus EeePC to be able to take advantage of SHE =) | Update: there is now a Jupiter Ubuntu PPA!


For a similar application, see Eee Control.

It uses Cairo / OpenGL to render graphics (many in correlation with Compiz) with full hardware acceleration. It's fully configurable and fully customisable and can be used as a taskbar too. You can easily add applets in the dock or as a desklet. It is recommended to install the PLUG-INS package (cairo-dock-plug-ins) to have access to more views, dialogs and many plug-ins and applets. Some screen shots are available : http://pics.glx-dock.org This package is the core of Cairo-Dock project.

install Matlab 2007 on windows 7

To install Matlab 2007 on windows 7
1-Change Windows 7 Theme to the classic one (windows classic)
2-now the Matlab install will work correctly

To use Matlab with other windows 7 themes you have to change java used by matlab.
1- download latest java version and install it.
2- go to C:\Program Files\MATLAB\R2007a\sys\java\jre\win32 you will find a file named jer1.5.0_07 rename it to Original_jer1.5.0_07
3- go to C:\Program Files\Java you will find file named jet6 (jetX for Xversion) copie it to C:\Program Files\MATLAB\R2007a\sys\java\jre\win32
and rename it to jer1.5.0_07
Now you can use matlab with all themes.

And I also find that we can actually modify jre.cfg file. It contains a number X, which indicate the version of java, and matlab would read the folder "jrex". So we can set x to "6" instead of renaming the folder of the new jre6.
