Facebook, Twitter & Ubuntu Lucid Lynx

Former Ubuntu logo. New version at File:Ubuntu...
PCs running Ubuntu will be getting more social thanks to changes that will set the popular Linux distro's look and feel for the next five years.
Lucid Lynx, released last April, will bring social applications like Twitter and Facebook directly into the software, Ubuntu founder Mark Shuttleworth has said in an interview here.

Apparently, the idea is to merge the desktop and online worlds, so people don't have to fire up their browser or a separate application to use their social applications.

Also coming is what Shuttleworth called "new styling" for the Lucid Lynx desktop. He didn't provide further details, but Shuttleworth has been a consistently keen advocate of the need to improve the design, not just the user experience, of Linux through Ubuntu.

"There will be some shiny, new bling on the desktop - we will have some new styling, which is going to be the starting point of another five-year view. We've bee human for the last five years - now we are going to be light oriented," Shuttleworth told Dell's cloud computing evangelist Barton George.

Shuttleworth also promised big changes for the version of Ubuntu targeting netbooks after Lucid Lynx.
Shuttleworth on March 1 will step down as chief executive of Canonical, the commercial sponsor of Ubuntu, and take on a more technology oriented role, working on Ubuntu. He said he's putting "a lot of time" into the Ubuntu Netbook Remix, saying it will go through what he called a period of rapid evolution in the next cycle after Lucid Lynx.

He also claimed that Linux - and particularly Ubuntu - is growing on netbooks in the wake of Microsoft's release of Windows 7 and the disappearance of Windows XP.

"There was some speculation around the death of the netbook," Shuttleworth said. "We haven't seen that. With Windows 7 out there, people have a real choice between free software and proprietary software, and it turns out free software is a popular choice.

"The share of Linux on netbooks seems to be growing now that XP's getting downplayed and we want to be right in the thick of that."
He was also optimistic about uptake of Ubuntu on mobile devices like smart books and said he was starting to see innovation around ARM-based devices since the release of Ubuntu 9.4 that officially put the disto on this hardware architecture popular in mobile devices.

Ahead of that, Lucid Lynx will have a "strong focus" on cloud, which as an LTS release is a major milestone. Lucid Lynx will rollout as people put into production the clouds they've built and tested on features that were introduced in Ubuntu last year for users to build Amazon EC2 images on their Linux systems.

Need Help With Ubuntu
Join Now Only $5.50 USD
GNOME (GNU Network Object Model Environment) is a desktop environment created for the operating system
GNU / Linux Desktop Environment is recognized as the official GNU project. With the announcement of version 3.0 was introduced GNOME-Shell, which integrates various functions into a 'single window.  The desktop area is divided into several parts depending on the activities and workspaces is dynamic: you can add or remove workspaces and you can move any applications in different areas of work, as already happens with Compiz.

Now you can see How  to install GNOME on  Ubuntu 10.4 Lucid Lynx

     First  you have to install
all the dependencies needed to successfully build and run gnome-shell.

     $ sudo apt-get build-dep gnome-shell

   After installing all the packages necessary steps for installing veritable gnome-shell

     $ sudo apt-get install gnome-shell

 Once installed, you can start GNOME-Shell by typing the following command in a terminal:

     $ gnome-shell --replace

GNOME-Shell is still under development and therefore very unstable.
Try it in your Test machine or in a Virtual machine.

Beginners Guide to the Ubuntu Terminal

Tux, as originally drawn by Larry EwingImage via Wikipedia












The Terminal window is often a barrier for new Linux users blocking them from effectively using the Linux desktop. Many users have been using point and click methods of desktop navigation since MS-DOS in the 80s. The idea of typing text into a command window can be a bit overwhelming for todays average computer user but it shouldn't be. Today we'll be using the Ubuntu 8.10 desktop which is available for download here
The advantages of using the command-line Terminal to accomplish tasks are great. The speed of using the terminal in a fraction of that it takes to accomplish the same task graphically. Try installing a package using the synaptic package manager. That would include at least six clicks of the mouse and typing in the root password once. Or you could use the terminal by clicking on Applications --- Accessories --- Terminal. (Kubuntu users click Menu --- System --- Konsole, Xubuntu users click Applications --- Accessories --- Terminal) Once you've opened the Terminal with your first click you can type 
sudo apt-get install amarok
Then enter the root password and that's it. You package will be downloaded and installed from the terminal window.
From this example you can see the difference in speed, but another advantage of using the Terminal window is the return you get when something goes wrong. If you're using the GUI desktop to accomplish a task and something happens you generally get a one line description but if you're using the Terminal you will receive a more in-depth description of your problem. Yet another advantage to using the command-line Terminal is the universal element that giving commands holds over using a GUI. As you can see from even trying to locate the Terminal, the path to accomplishing a task with the GUI may vary when you're using Ubuntu, Kubuntu, Xubuntu etc. While Terminal commands aren't always the same in different distributions, you can issue the same commands for Ubuntu, Kubuntu, Edubuntu, Xubuntu and count on their effectiveness.
If you prefer to point and click instead of typing any commands into the Terminal you may find shelter under a few other Linux distributions like Mepis, Linspire and a few others. And also this all depends on what you use your computer for. If you play Solitaire and use the Internet to interact with your friends and that's it, it's possible you may never need the Terminal window on Ubuntu.
Lets take a look at some very simple commands on the Ubuntu desktop that will allow us to effectively accomplish some small tasks. After you've opened the Terminal window you can start typing in the commands. Below is a list of some useful commands and what they are used for.
  • sudo command – run command as root
  • apt-get - used to install, remove, upgrade and more.

Setup easy web development environment (XAMPP)

vector version of this imageImage via Wikipedia
This is a how-to for setting up a web development environment easily. This guide will install the XAMPP lampp stack into /opt, setup an easy way to start it up and shut it down, and link a folder in your home directory to the webserver.

WARNING
This guide is aimed at a development environment only and should not be used as a public webserver. To setup a public webserver follow the directions on the Ubuntu wikihttps://help.ubuntu.com/community/ApacheMySQLPHP

As this is Ubuntu, all the major parts of a typical web server are included (in the main repo, or on the Ubuntu Server CD) and this is a great way to setup a server. The ubuntu developers have prepared a great web server and have made the process as seemless as possible.

But what if even the official way is still to complicated? What if you just want a quick web server for development?

Fortunately there is the XAMPP project: http://www.apachefriends.org/en/xampp.html. The XAMPP project bundles Apache, PHP4 & 5, Perl, mySQL, and a bunch of other utilities/applications into an simple package for Mac OSX, Windows, Solaris, and Linux. Obviously this HOWTO only deals with the linux version.

For those of you with already existing Apache/mySQL/php installations it installs everything into /opt so it doesn't conflict with any other installation, and it is completely setup and ready to run.

Install XAMPP

Two easy steps:








  1. Download the most recent version of XAMPP: (at time of writing 1.5.3a)
    http://prdownloads.sourceforge.net/x...ar.gz?download
    (Source URL: http://www.apachefriends.org/en/xampp-linux.html#374)
  2. Extract the archive to /opt using sudo: (make sure you are in the directory that you downloaded the archive to)



    Code:
    sudo tar xvfz xampp-linux-1.5.3a.tar.gz -C /opt

Start XAMPP

To start it up, open a terminal and type this:




Code:
sudo /opt/lampp/lampp start
Stop XAMPP

To stop it, open a terminal and type this:



Code:
sudo /opt/lampp/lampp stop
Additional XAMPP commands

To see additional commands, open a terminal and type this:



Code:
sudo /opt/lampp/lampp
Sweet XAMPP Control Panel



To use the sweet gtk/python control panel:

Run in a terminal:



Code:
gedit ~/.local/share/applications/xampp-control-panel.desktop
Paste the following into the open file and save and exit.



Code:
[Desktop Entry]
Comment=Start/Stop XAMPP
Name=XAMPP Control Panel
Exec=gksudo "python /opt/lampp/share/xampp-control-panel/xampp-control-panel.py"
Icon[en_CA]=/usr/share/icons/Tango/scalable/devices/network-wired.svg
Encoding=UTF-8
Terminal=false
Name[en_CA]=XAMPP Control Panel
Comment[en_CA]=Start/Stop XAMPP
Type=Application
Icon=/usr/share/icons/Tango/scalable/devices/network-wired.svg
"XAMPP Control Panel" will show up in your applications menu under Internet. Use the Alacarte Menu Editor to move it around.

Test to see if XAMPP is running

Once XAMPP is up and running open firefox and go to: http://localhost/

You should see the XAMPP test page:



Location of files and uploading

XAMPP by default uses /opt/lampp/htdocs as the root web directory. The easiest way to start working on files is to link a folder in your home directory into this directory.
My user name is peter so I have /home/peter/public_html linked to /opt/lampp/htdocs/peter. So if I navigate to http://localhost/peter/ I get a listing of all the files/folders in that directory. (As long is there isn't a index.php/html/etc file)
To set this up, run in a terminal:


  1. Make public_html directory in home directory:



    Code:
    mkdir ~/public_html
  2. Link to /opt/lampp/htdocs



    Code:
    sudo ln -s ~/public_html /opt/lampp/htdocs/$USER
Now any files and folders you place in ~/public_html will be published to your personal webserver.

Bookmark http://localhost/username to make this easy to access.

WARNING - SECURITY
http://www.apachefriends.org/en/xampp-linux.html#381
Open holes:



  1. The MySQL administrator (root) has no password.
  2. The MySQL daemon is accessible via network.
  3. ProFTPD uses the password "lampp" for user "nobody".
  4. PhpMyAdmin is accessible via network.
  5. Examples are accessible via network.
  6. MySQL and Apache running under the same user (nobody).
This doesn't leave your whole system wide open, but someone could hack your XAMPP installation, so be wary.
To fix most of the security weaknesses open a terminal and run:


Code:
sudo /opt/lampp/lampp security

Getting Quickbooks Online to work in Firefox

Mozilla Firefox IconImage via Wikipedia
In linux or mac, install the user agent switcher from here:

https://addons.mozilla.org/en-US/firefox/addon/59

then go to tools > user agent switcher > options > options

then do add:

Description : Firefox 3 (Windows XP)

User Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.6) Gecko/2009011913 Firefox/3.0.6

App Name: Mozilla Firefox

App Version: 5.0 (Windows; en-US)

Platform: Win32


Then switch to it from tools, and go!

You won't be able to print pdfs (actually you will, but not the way quickbooks would like you to) until you install adobe pdf reader.

here's how:
Make sure the medibuntu repositories are enabled.
https://help.ubuntu.com/community/Medibuntu

sudo wget http://www.medibuntu.org/sources.list.d/intrepid.list --output-document=/etc/apt/sources.list.d/medibuntu.list

then

sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update

sudo apt-get install acroread acroread-plugins mozilla-acroread

Then open firefox again, and you should be able to print documents or whatever.
