Our meetings will consist of a group of Linux enthusiast wanting to gain or trade their expertise to talk about the latest news and software releases related to Debian/Ubuntu (Client & Server). Together, we will assist each other in setting up labs for hands-on exercises with migrating to Debian/Ubuntu client software as their primary operating system, to running their own home-based Debian/Ubuntu servers.

Intro
To install Ubuntu, at least 384 Megabytes of memory are required. However, it is possible to install Ubuntu on a PC with only 128 MB of RAM, with a full Gnome desktop.
Here’s how…
Prerequisites
* A PC with 128 MB of memory or more.
* A CD-Rom drive
* 3 Gb of free space on hard drive.
* An Ethernet card recognized by Ubuntu
* Internet connection (preferably Ethernet).
The Internet connection is necessary because the installation is done via the network. Download and burn the installation CD of Ubuntu (MinimalCD): here.
This ISO image (13 MB) allows installation of Ubuntu directly via the internet.
Installation
* Boot from the minimal CD and choose “Command-line install”.
* Proceed with the installation of the system. At the end of the installation, after rebooting, you get a text mode.
* Login with the username and password you chose during installation.
(Plymouth errors can be ignored.)
Installing core packages
Then, install the base packages below to get a graphical desktop (Gnome).
sudo apt-get install gnome-core gdm gnome-system-tools network-manager-gnome human-theme x11-xserver-utils tangerine-icon-theme gnome-themes-ubuntu gnome-themes-selected ubuntu-artwork jockey-gtk gnome-screensaver xcursor-themes gnome-utils file-roller
(Note: It is possible to have an lighter GUI with JWM or IceWM , but you lose the benefits of the Gnome/Ubuntu integration.)
Reboot: (sudo reboot): You can now login to your GUI.
You may get a popup error about “FastUserSwitchApplet”: Just click the “Remove” button.
Installing additional software
When choosing software, it is recommended to avoid heavy ones such as OpenOffice.org.
Here are some recommended packages for a basic system:
sudo apt-get install gcalctool brasero chromium-browser abiword gnumeric vlc p7zip-full ubuntu-restricted-extras
Details:
* Chromium : Chromium is lighter than the Firefox browser and based on Webkit (like Chrome or Safari).
* gcalctool, a calculator.
* brasero : CD/DVD burning application.
* abiword is a word processor lighter OpenOffice.org Writer.
* gnumeric spreadsheet is a good alternative to OpenOffice.org Calc.
* VLC is a media player (audio/video) that can play almost any format.
* p7zip-full can read many different archive formats (cab, rar …)
* ubuntu-restricted-extras: Flash plugin, Java, codecs, Microsoft TrueType fonts, etc..
* The system is already provided with Evince, a PDF reader.
You are with a basic system for surfing the internet and perform office duties.
Thanks to Seb-Sauvage for this tip.

To reset your Windows password is very easy, as easy as resetting your Ubuntu password. What you need is bootable Ubuntu system (ie. USB, CD or anything) and software called chntpw.
This is step-by-step to reset your Windows password:
- Boot from your bootable device (Ubuntu Live Session)
Shutdown your computer and boot up using your bootable system. So you run Ubuntu on Live Session that means you run your system without install it!
- Set your repository
Goto Synaptic Package Manager -> Settings -> Repositories -> Ubuntu Software and check the “Software restricted by copyright or legal issues
” checkbox. And don’t forget to reload synaptic.
- Install CHNTPW
Install from Synaptic Package Manager or use this command on shell:
sudo apt-get install chntpw
- Resetting Windows password
- Mount your “Windows installed” device
It’s depending on your system, example:
sudo mkdir /media/WINDOWS
sudo mount /dev/sda1 /media/WINDOWS
On my system Windows installed on /dev/sda1 and I want to mount it to /media/WINDOWS that I’ve created before.
- Goto your Windows system configuration folder
Located at [WINDOWS_DEVICE]/WINDOWS/system32/config/:
cd /media/WINDOWS/WINDOWS/system32/config/
- Cracking the SAM file
There a SAM file on Windows system configuration folder. That’s the file we’re looking for. Let’s crack it 
(sounds cool)
chntpw SAM
And if you see the output similar with image below, it’s mean you can crack the SAM file.
As you see, there is 5 choices. Just type “1″ and press “ENTER” to reset your password. –Done.

Are you planning to use your Apple® iPad™ Wi-Fi + 3G outside of the U.S.? Before you travel, be sure you do the following things:
Check for international coverage for your destination:
1. Identify the AT&T roaming partners for your destination country by visiting att.com/dataconnectglobal.
2. Then, find the roaming partner for your destination at www.gsmworld.com/roaming/gsminfo/index.shtml and select the Coverage Map link to view coverage for the country with that provider.
Availability, quality of coverage, and services while roaming are not guaranteed. Use of services when roaming is dependent upon the AT&T roaming partners’ support of applicable network technology and frequency.
Purchase International AT&T 3G Data Plan for iPad:
You can purchase an international data plan when you activate your domestic plan or at any time. With the international plans, you can set the date when you want the plan to activate – it does not have to start on the day purchased.
It is recommended that you purchase your international plans before you travel outside of the U.S. If your travel plans require more than 30 days or 200 MB of data, you can purchase additional plans and set them to start when the previous plan is depleted. If you are outside of the U.S. and want to purchase an international plan, you can purchase online with a Wi-Fi connection.
Customers must have an active domestic plan if they want to purchase an international plan. Unlike domestic plans, international plans will not auto-renew. International data plans are only good for 30 consecutive days or until you have used all the data included in your plan. iPad Wi-Fi + 3G will work on Wi-Fi networks internationally. However, these networks are not part of the 20,000 free AT&T Wi-Fi Hot Spots for AT&T customers. You may need to pay for Wi-Fi access, depending on the Wi-Fi provider.

Overview
WordPress is one of the most popular blogging and site-building applications available today. Its popularity amongst users is not without reason; WordPress has done an excellent job of empowering beginners by creating an intuitive administration panel, which enables users to post content and customize their sites without any knowledge of HTML or PHP. However, more expert users find the software extremely flexible and very tightly-coded for easy modification and customization.
Features
WordPress enables you to:
* Easily edit posts and pages right in your browser with a rich-text editor (no download/upload necessary).
* Create a full site by adding and modifying pages that aren’t blog posts.
* Switch between site themes, upload new, free themes from the powerful library of templates on WordPress.org, or even create your own.
* Allow multiple authors to post and edit–and customize their permissions.
* Make certain posts password-protected.
* Post to the future–just pick the date and time, and pre-written content will post automatically.
* Integrate various types of media (photos, videos, mp3s) to personalize your posts.
* Organize content into categories and subcategories and tag posts with keywords.
* Choose if readers can post comments or not–and if comments are enabled, require only registered users to comment and/or review comments before they’re made live.
* Protect your blog from SPAM with WordPress’s out-of-the-box tools or easy-to-install plugins.
* Connect with other blogs through WordPress’s support of automatic Trackback and Pingback standards.
* Integrate RSS feeds so readers can automatically keep up with your latest posts, comments and more.
* Take advantage of their full library of free plugins for further customization of your blog.
