Saving Power on Intel Hardware Using Powertop

PowerTOP is a Linux tool that finds the software component(s) that make your laptop use more power than necessary while it is idle. As of Linux kernel version 2.6.21, the kernel no longer has a fixed 1000Hz timer tick. This will (in theory) give a huge power savings because the CPU stays in low power mode for longer periods of time during system idle.

However... there are many things that can ruin the party, both inside the kernel and in userspace. PowerTOP combines various sources of information from the kernel into one convenient screen so that you can see how well your system is doing, and which components are the biggest problem.

Requirements

For PowerTOP to work best, use a Linux kernel with the tickless idle (NO_HZ) feature enabled (version 2.6.21 or later). Currently, only 32-bit kernels have support for tickless idle; 64-bit kernels are expected to gain this feature in version 2.6.23.

This only applies to Feisty. Also note that you need kernel 2.6.21 or above.

Install the following prerequisites

sudo apt-get install build-essential libncurses5-dev libncursesw5-dev

Download the latest powertop source from here

Put the source in /usr/src and unpack using

sudo tar -xvf powertop-1.8.tar.gz

Compile using the following command

cd powertop-1.8

sudo make

sudo make install

You can also use "checkinstall" instead of "make install" to create a simple .deb for easier removal.

Run powertop using the following command

sudo powertop

Powertop Output shown as follows

Ubuntu 7.10 (Gutsy Gibbon) Release Dates

In addition to Ubuntu 6-months stable releases and the next version of ubuntu is 7.10 with Code Name “Gutsy Gibbon”.

Mark Shuttleworth about Ubuntu 7.10 (Gutsy Gibbon)

On a personal note, the monkey on my back has been composite-by-default,which I had hoped would happen in Edgy, then Feisty. I'm nervous to predict it now for Gutsy, for fear of a third strike, but I'm told that great work is being done in the Compiz/Beryl community and upstream in X. There's a reasonable chance that Gutsy will deliver where those

others have not. I remain convinced that malleable, transparent and extra-dimensional GUI's are a real opportunity for the free software community to take a lead in the field of desktop innovation, and am keen to see the underlying technologies land in Ubuntu, but we have to balance that enthusiasm with the Technical Board's judgement of the stability and maturity of those fundamental layers.

Now you can make a note of ubuntu 7.10 (Gutsy Gibbon) release dates in you calender

Details about Each Release

Feature Freeze

The point at which we cease creating and modifying internal features and packages. This means we’re pretty much locked down for bugfixes only.

Exceptions requiring confirmation

Packages in or relating to high-priority ReleasenameFeatureGoals

Major/minor fixes, within reason

Exceptional circumstances

Upstream Version Freeze

The point at which we cease accepting new upstream versions of packages, whether they are sourced from Debian or not. Selected Debian releases of the same upstream versions may still be pulled in for bug-fixes, but this would be a manual process.

Exceptions requiring confirmation

Packages in or relating to FeatureGoals

Minor fixes, if the upstream change is a micro-increment (or equivalent)

Major fixes, particularly blockers, if the upstream change is a minor-increment (or equivalent)

Exceptional circumstances

String Freeze

A string freeze is initiated in the project when all the human readable portions of code are no longer allowed to change. This gives the translation teams a chance to complete their translations without having to redo changed text. It also allows documentation to mention the actual UI names and messages.

Beta Freeze

Anal-retentive, high-caution period until the Beta Release goes out. Release and relevant section team confirmed fixes only! Once the BetaRelease is shipped, we roll back to FeatureFreeze status.

Exceptions requiring confirmation

ReleaseCriticalBug

SecurityCriticalBug

Exceptional circumstances

Beta Release

The BetaRelease is a testing oriented pre-release, usually one month before the Final Release.

Non Language Pack Translation Deadline

Some translation data cannot currently be updated via the language pack mechanism. Because these items require more disruptive integration work, they are subject to an earlier deadline. Translations which fall into this category are:

The Ubuntu installer

Translations which don’t use gettext, including:

Firefox

debconf templates

desktop notifications via notification-daemon

Strings visible in the default desktop (live CDs don’t get language pack updates)

Default menu items

Panel strings

All menu entries in KDE applications, which does not support translation via language packs

Kernel Freeze

The kernel freeze is a deadline for kernel updates, since they require several lockstep actions which must be folded into the CD building process. As with other freeze dates, exceptional circumstances may justify exemptions to the freeze, at the exception of the release managers.

Release Candidate (RC)

The release candidate is a production-quality pre-release one week before the final release.

Language Pack Translation Deadline

Translation data using the Language Pack mechanism is due at this deadline.

See NonLanguagePackTranslationDeadline for non Language Pack data.

Final Release

The final release is the finished product which is distributed with an official Ubuntu release number.

Desktop Data Manager(DDM) for Ubuntu Desktop

How To Import mails from Evolution to Thunderbird

If you want to Import your mails from Evolution to Thunderbird there is very nice utility called MboxImport .

Thunderbird, like many other email clients, uses the mbox format to archive the emails.It's curious that Thundebird has not a function that let you import or export files in this format and this lack is sometimes a problem when you want to move the accounts from a pc to another one or when you want to migrate (for example) from Mozilla to Thunderbird.Anyway this kind of import can be made very easily copying the mbox file into the directory "Local Folders" (it is inside the profile directory) with Thunderbird close; restarting the program, the mbox file will be visible as sub folder of Local Folders.To export, you must just copy the email files that are inside the account's folder.This method can give some troubles, above all for people not very expert with Thunderbird, because the profile's files are into a hidden directory, whose path changes with the operative systems or also with personal needs.

First you need to download MboxImport from here

Install MboxImport in Thunderbird

In Thunderbird, go in "Tools" --> "Extensions" and click on "Install";

pick the xpi file you downloaded and follow the instructions;

restart Thunderbird.

To export, it's sufficient a right-click on the folder or on the account and to choose the voice you want from the menu "Import/export".

Once you have saved all the folders/files into the Mbox format, just go into Evolution and select "Import" and follow the wizard using "a single file import" and select your xxxx.mbox file and then select which folder in Evolution you want to import into.

For importing the address book from Thunderbird to Evolution, use T-birds address book export function and save the address book as a .csv file.After finishing address book check everything is fine or not.

Now you can access at http://youripaddress:7878

Adding files to gnump3d

Now, you'll probably want to add some files to gnump3d. The default directory is /var/music.

There are many different ways to copy files into your server from another Ubuntu machine,More secure way is using openssh. On the Ubuntu box that you want to copy the files from, open a terminal and type

sudo apt-get install openssh

Assuming that the path of a folder to copy is /home/username/music and the local IP of the remote Ubuntu computer is xxx.xxx.x.xxx, and the directory where the copied files will go is /var/music, go you your server and type

cd /var/music sudo su scp -r username@xxx.xxx.x.xxx:/home/username/music

Once you copied some files you should see similar to the following screen
