Libre Office 3.3 in Ubuntu

LibreOffice is the spinn-off of Open Office.
It gives you six feature-rich applications for all your document production and data processing needs: Writer, Calc, Impress, Draw, Math and Base. It will be the standard in Ubuntu from 11.4, but you allready can use it in Ubuntu 10.10.

To install Libreoffice 3.3 open a Terminal window (Applications -> Accessories -> Terminal) and copy+paste the following lines:

sudo add-apt-repository ppa:libreoffice/ppa
sudo apt-get update
sudo apt-get install libreoffice

To integrate it into your desktop do

sudo apt-get install libreoffice-gnome
For GNOME users and do


sudo apt-get install libreoffice-kde
for KDE Users.

When installed you can find LibreOffice under Applications -> Office.
LibreOffice

The homepage of LibreOffice Homepage.

Update nvidia drivers in ubuntu

Here is a guide to update your nvidia driver to the latest version (260.19.29). The current ubuntu version is 260.19.06

To install the latest driver open a Terminal window (Applications -> Accessories -> Terminal) and copy+paste the following lines:


sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current nvidia-current-modaliases nvidia-settings


When installad go to System -> Administration -> Additional Drivers and activate the current Nvidia driver (if needed) then reboot your system.

It seems the newest version is 270.18
It will be insytalled from this ppa as well.

Stellarium PPA

You can update your system with unsupported packages from this untrusted PPA by adding ppa:stellarium/stellarium-releases to your system's Software Sources. 
If you're using the most recent version of Ubuntu (or any version from Ubuntu 9.10 onwards), you can add a PPA to your system with a single line in your terminal:

sudo add-apt-repository ppa:stellarium/stellarium-releases
sudo apt-get update
sudo apt-get install stellarium 

 
Technical details about this PPA

This PPA can be added to your system manually by copying the lines below and adding them to your system's software sources.
Display sources.list entries for:
 
deb http://ppa.launchpad.net/stellarium/stellarium-releases/ubuntu maverick main 
deb-src http://ppa.launchpad.net/stellarium/stellarium-releases/ubuntu maverick main 
Signing key:
1024R/C68D72A5 
Fingerprint:
4283D01497ADF8D09CFA9B6C1932F485C68D72A5

On older (pre 9.10) Ubuntu systems

Step 1: Visit the PPA's overview page in Launchpad. Look for the heading that reads Adding this PPA to your system and click the Technical details about this PPA link.
Step 2: Use the Display sources.list entries drop-down box to select the version of Ubuntu you're using.
Step 3: You'll see that the text-box directly below reads something like this:
deb http://ppa.launchpad.net/gwibber-daily/ppa/ubuntu jaunty main deb-src http://ppa.launchpad.net/gwibber-daily/ppa/ubuntu jaunty main Copy those lines.
Step 4: Open a terminal and type:
sudo gedit /etc/apt/sources.list This will open a text editor containing the list of archives that your system is currently using. Scroll to the bottom of the file and paste the lines you copied in the step above.
Save the file and exit the text editor.
Step 5: Back on the PPA's overview page, look for the Signing key heading. You'll see something like:
1024R/72D340A3 (What is this?) Copy the portion after the slash but not including the help link; e.g. just 72D340A3.
Step 6: Now you need to add that key to your system so Ubuntu can verify the packages from the PPA. In your terminal, enter:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 72D340A3 Replace 72D340A3 with whatever you copied in the step 5.
This will now pull down the PPA's key and add it to your system.
Step 7: Now, as a one-off, you should tell your system to pull down the latest list of software from each archive it knows about, including the PPA you just added:
sudo apt-get update

Command Line Time-Saving Shortcuts

On the site of Lifehacker, I found this very interesting posting: A copy is here for my convenience.


The command can be quite powerful, but typing in long commands and file paths gets tedious pretty quickly. Here are some shortcuts that will have you running long, tedious, or complex commands with just a few keystrokes.
Power users love the command line for its ability to perform complicated tasks with just a few keystrokes. But for beginners who don't know the shortcuts and type everything out longhand, it can seem like it takes forever (I know this because I'm just past beginner myself, and I still didn't know most of these shortcuts).
These commands apply primarily to *NIX-based command lines, which, out of the box, are included on systems like OS X and Linux. To use them on Windows, install Cygwin. (We highly recommend ditching Windows' crappy command line for Cygwin.)
From simple keyboard shortcuts to built-in shorthand to commands you can build and customize yourself, the Terminal has a ton of ways you can speed up your command line work, and here we're going to show you some of the basics (as well some customizable features that you can use to shorten pretty much any command you want).
If you're just getting started with the command line, we recommend you also check out our command line primer for beginners. Heck, even if you're not a beginner, skim through it—you're sure to find a few things you didn't know. We'll be touching on a few of those subjects and building on them here, too.

Basic Keyboard Shortcuts

We went through a few basic keyboard shortcuts in our beginner's guide, but there are quite a few in there that, while not exactly intuitive, are incredibly useful just for navigating the shell. They also come in handy when you want to refer back to previous commands.
  • Up/Down Arrows: The up and down arrows on your keyboard move through your last used commands. So, if you wanted to run the second to last command you ran, just hit the up arrow twice and hit Enter. You can also edit the command before you run it.
  • Ctrl+Left and Ctrl+Right: Hitting Ctrl and the left or right arrow keys jumps between arguments in your command. So, if you had a typo in the middle of the command, you could jump to it quickly with Ctrl and a few taps of the left arrow key. Note that on Mac OS X and Windows, this shortcut is Esc+B and Esc+F instead. This is pretty awkward, but OS X users can change it from the Terminal's preferences if they so choose.
  • Home and End: The Home and End buttons on your keyboard move your cursor to the beginning and the end of the currently typed command, respectively. This is useful if you've, say, typed in a command but realize that there's a typo in the first word. Instead of holding down the left arrow key, just hit home and correct it. You can also do the same thing with Ctrl+A and Ctrl+E, respectively (on Mac OS X, Ctrl+A and Ctrl+E are the only way to do this).
  • Ctrl+U: This clears the entire line so you can type in a completely new command.
  • Ctrl+K: This deletes the line from the position of the cursor to the end of the line.
  • Ctrl+W: This deletes the word before the cursor only.
  • Ctrl+R: This lets you search your command history for something specific. For example, if you wanted to search for the recent commands that included nano, you would hit Ctrl+R and type nano. It would show your most recent command, and you could use the up and down arrows to cycle through your history of commands using nano in them.
  • Tab: One of everyone's favorite shortcuts employs Tab to autocomplete a line of text. So, say you wanted to type cd ~/Dropbox/, you could just type cd ~/Dr, hit Tab to autocomplete opbox, and continue on with your day.

Terminal Shorthand

Whether you make a lot of typos, run a lot of the same commands over and over again, or you're dealing with long, annoying file paths, the Terminal has quite a bit of built-in shorthand to keep you from typing everything out yourself. Here are a few great examples.

File Paths

When you're working with files in the Terminal, navigating the folder structure of your system can take forever. Constantly typing long filenames is never fun, so here are a few tricks that'll get those 5-folder-deep paths into the Terminal with just a few taps of your mouse or keyboard.

Dragging Files Into the Terminal Window

If you have a file buried deep within your hard drive, typing out its full path can take forever. Instead of doing that, you can just open up the folder in Nautilus, Finder, Dolphin, or whatever file manager you use and drag the file right into the Terminal window. It will add its file path to the current command.

File Path Shorthand

We discussed these briefly in our beginner's guide, but they bear repeating. Say you're cding around your hard drive but don't want to type out file paths over and over again. If you need to continually access the same folders or files, dragging them in from your file browser can even get tedious. Luckily, you can substitute your current directory and its parent directory with . and .., respectively. For example, if you cd to a folder, running the following command will move you one folder up.
cd ..
That way, you don't have to retype the entire file path (or even hit the up arrow and delete a folder name—it's literally just a few keystrokes).
This also works if you're typing out longer paths. Say you're in ~/Documents/Work and you wanted to be in ~/Documents/Play. You could just type:
cd ../Play
and get there instantly.
Another good shortcut is the dash (-). This will move you back to your last working directory:
cd -
Thus, if you're working in, say, your documents folder (~/Documents) and moved over to the /etc/ briefly, you could switch right back by typing cd - and hitting Enter.
Lastly, if you want to go back to your home directory, there's no need to add any arguments to the cd command. Just typing cd and hitting enter will bring you back home.

Using Your History

Accessing recently used commands (or running a small variation of recently used commands) is something Terminal users often need to do. Unfortunately, it's also one of the most tedious parts of the Terminal—who wants to retype the exact same command they just ran but with one minor difference? It makes every typo seem like a punishment. Luckily, there's some pretty nice shorthand, most of which uses the handy bang symbol (!).
One of the most useful shortcuts is using !! to represent the last command you ran. This is useful in a ton of situations. For example, if you run a command that needs root privileges but forget to add sudo to the beginning, there's no need to retype the command. Just run:
sudo !!
This will run your last used command with root privileges.
If the command you want to run is a bit further back in your history, you can use the bang in conjunction with the original string to find it. For example, if you want to run the last command that used cat, you could just type:
!cat
If you just want to see what the last cat command was, you can instead run:
!cat:p
This will print that command and add it to the end of your history. If you decide you then want to run it, you can just type !! and hit Enter.
If you want to run a different command that you ran last, but with the same argument, there's a shortcut for that too. For example, say you had just created a folder using:
mkdir /new/awesome/folder
To then cd into that directory, you could just type:
cd !$
The !$ represents the arguments from your last command.
Another common problem is mistyping the command you want to run. Say you wanted to run nano, but accidentally typed nanp:
nanp /path/to/a/document/buried/deep/in/the/filesystem
Instead of retyping the whole thing, you could just run:
^nanp^nano
This will find the first instance of nanp in the last run command and replace it with nano.
While all these shortcuts are fine and dandy, but it's worth mentioning that the history command is your friend. If you want to see all the recent commands you ran that included nano, for example, you could just run:
history | grep nano
You'll get a list that looks something like this:
381 sudo nano /etc/NetworkManager/nm-system-settings.conf
387 sudo nano /etc/rc.conf
388 sudo nano /etc/rc.conf
455 sudo nano /boot/grub/menu.lst
You can then pick a command out from that list—say I want to run sudo nano /boot/grub/menu.lst, which grep lists as command 455—and run it using:
!455
Lastly, if you want to keep certain commands out of your history, just put a space before them—i.e. space+nano ~/Documents/WorldDominationPlans.txt.

Expansions

When you're working with variations of a file—like backups or different file types—it can get tedious typing out the same commands with small tweaks. Using the brace symbols ({}), you can easily perform batch operations on multiple versions of a file.
Say you want to rename just part of a filename. Instead of typing out mv /path/to/file.txt /path/to/file.xml, you could just run:
mv /path/to/file.{txt,xml}
This runs the command with the same arguments, only with the parts inside the brace changed—the first part corresponding to the first argument, the second part corresponding to the second argument.
The most common example of this is when you're backing up a file that you're making changes to. For example, if you are tweaking your rc.conf, you'll want to make a backup in case the new one doesn't work. So, to do so, you can just run:
sudo cp /etc/rc.conf{,-old}
Putting nothing before the comma will just append -old to the filename after copying it with cp. If your new file doesn't work out and you want to restore the backed up file to its original location, you can just use:
sudo mv /etc/rc.conf{-old,}
Moving the comma to the other end of the brace will remove -old from the end of the file and restore it to its original name.
The braces can also work when moving or creating multiple files at once. For example, if you wanted to create three numbered directories, you could just run:
mkdir myfolder{1,2,3}
This will create three folders: myfolder1, myfolder2, and myfolder3.

Making Your Own Shorthand

While these are all pretty handy, the most useful thing you can probably do is make up your own shortcuts. After all, we all have a few commands we run over and over again, but they aren't necessarily the same for everyone. To do so, we're going to edit the ~/.bashrc configuration file (or, if you're on Mac OS X Snow Leopard, ~/.bash_profile). It's a basic text file, so you can do it with whatever you like—Gedit in Ubuntu, TextEdit on OS X, or even nano within the Terminal. We've talked about doing this a few times before, but it really is one of the best things you can do to speed up Terminal work.
To create a custom shortcut (called an alias or function, you'll want to add a new line to your .bashrc file using the following format:
alias la='ls -A'
Now, whenever you type la, the Terminal will run ls with the -a modifier, which includes hidden files. Some of thsee are built into popular Linux distributions already, but there are a ton of other useful ones. Here are some of our favorites:
alias ll='ls -l'
This gives you a more verbose list of files than ls does on its own. In Ubuntu, this shortcut already exists, but runs ls -alF.
alias desk='cd ~/Desktop'
This will make your Desktop the working directory with just a few keystrokes. You can, of course, modify this for pretty much any folder that you access regularly.
alias up='cd ..'
This moves your working directory one folder up in half the keystrokes.
alias emenu='aterm nano -e ~/.e16/menus/user_apps'
This is an example of an alias that opens up a file for editing. If you have any files you find yourself constantly editing, this is a good one to keep around—just throw the path to your oft-used file in the quotes and edit the keyword to something that makes sense.
alias agi='sudo apt-get install'
With this, installing programs is much quicker in Ubuntu. You can just type agi chromium to install Chromium, for example. Of course, if you're using a different flavor of Linux, you can replace it with your package manager of choice.
alias update='sudo apt-get update'
This will update all your packages in Ubuntu.
function cdl { cd $1; ls;}
This is a neat function we've featured before that will essentially run cd and ls at the same time. So, just type cdl /path/to/folder and the Terminal will both make that your working directory and list its contents in one fell swoop.

Install Google Earth 6 in Ubuntu

To get Google Earth 6 to start, you need to install lsb-core.

In Ubuntu, install it like this by running these commands in a terminal:
 
sudo apt-get install lsb-core

Download the latest Google Earth 6 (.bin) and place it in your home folder.

Then run the following commands in a terminal:

cd /home/yourname
chmod +x GoogleEarthLinux.bin
./GoogleEarthLinux.bin --target /tmp/ge
 

The installer will start now. You can skip  the rest of this article.

But at this point, you'll sometimes get an error like this:

./GoogleEarthLinux.bin
Verifying archive integrity... All good.
Uncompressing Google Earth for GNU/Linux 5.1.3533.1731...............................................................
setup.data/setup.xml:1: parser error : Document is empty

^
setup.data/setup.xml:1: parser error : Start tag expected, '<' not found

^
Couldn't load 'setup.data/setup.xml'


Now enter these commands in a terminal to get the installer working:
 
cd /tmp/ge/setup.data/bin/Linux/x86/
mv setup.gtk setup.gtk2
cd /tmp/ge
sudo ./setup.sh



Notes: I've only tested this on 32 bit ubuntu systems.

Personal package Archive (PPA) manager

Article found on Maketecheasier

Installing applications in Ubuntu, in most cases, is as easy as going to the Ubuntu Software Center, search for the application and press the install button. However, there are times when the applications you are looking for is not available in the Ubuntu repository, or that the software version in the repository is outdated. This is when a deb file or a Personal Package Archive (PPA) comes in handy.The advantages of using a PPA is that you can add new application package to your existing repository and install it the way you normally do (by terminal or Ubuntu Software Center). Additionally, when there is new update in the application, you will be automatically upgraded.

With all that said, the only problem with PPA is that not all applications come with a PPA. And for those that have one, it can be difficult to find. For new users, adding the PPA involves the command line, which many people will shun as much as possible. Y PPA Manager aims to make the above process much easier.
Y PPA Manager is a simple tool that allows you to search for PPAs and install them without hitting the terminal. It also allows you to manage (add/remove/purge) your existing PPAs with a few clicks.

Usage

Open a terminal (hopefully this will be the last time you install PPA via the terminal) and type:
sudo add-apt-repository ppa:webupd8team/y-ppa-manager
sudo apt-get update
sudo apt-get install
Once installed, go to “Applications -> System Tools -> Y PPA Manager“.
yppa-main
There are few options for you to manage your PPAs

Add PPA

If you know the PPA, you can add it to your repository using the “Add PPA” option.
yppa-add-ppa
After Y PPA Manager has added the PPA, it will also run a update on your system to retrieve the package files. When it is done (it will notify you via the NotifyOSD), you can go to Ubuntu Software Center to install the application.

Remove PPA

When you select the “Remove a PPA” option, it will show you all the existing PPAs you have installed in your system. You can then select the one you want to remove.
yppa-remove-ppa

Search for PPA

The best part about the Y PAA Manager is that you can search for PPAs right within the app. Double click the “Search All LaunchPad PPAs” option and perform your search. If there are matching results, it will display in a new window and you can then select the PPA and install it in your system.
yppa-search
yppa-select-install-ppa

Purge PPA

Removing a PPA only prevents the application from being updated. Your installed application will still be the same. On the other hand, purging a PPA will downgrade the packages to the version in the official Ubuntu repositories and disables that PPA. In Y PPA Manager, you can also purge a PPA with the “Purge a PPA” option. Similarly it will display the list of installed PPA and you just select the one you want to purge.

Wrapping up

Most of the functionality in Y PPA Manager are just wrapper for the commonly used commands. Seasoned users might prefer the command line more than using this application, but I am sure that new (or novice) users will appreciate the simplicity and usefulness of this app, and also save you from the terror of the terminal.
One thing that I hope to see is the ability to install applications right after I have added a PPA. People don’t add PPA for fun. They will add PPA so that they can install certain applications not found in the repository. If Y PPA Manager can show the respective applications after adding the PPA and provide an option for the user to install the app, it will be perfect.

Airplay in Totem

A new plug-in for Totem movie player allows the app to receive and play AirPlay-streamed video.

AirPlay comes to Totem
AirPlay is a proprietary service from Apple ‘which allows a computer, iPhone, iPod, or iPad with the iTunes music player or iOS 4.2 to send a stream of music, video, or photos to multiple devices such as an AirPort Express, Apple TV or other AirPlay enabled device.’
Ubuntu One announced support for streaming music using AirPlay via the official Ubuntu One client for iPhone late last year.

Download

The plugin is hosted on the sukimashita.com git repositories located here.
Install by first cloning the repository
then moving the files into
~/.local/share/totem/plugins/airplay
creating directories where needed. Finally enable the plugin through the Totem Plugin menu.

privacy on the internet

A part of this interesting article about privacy on the internet

On the internet, sometimes the best form of privacy is being anonymous. It's difficult for an attacker to get to you if they can't pinpoint you on the network. And no one covers your tracks better than the combination of Privoxy and Tor.
Tor protects privacy via a distributed network of relays run by volunteers spread across the world. This helps prevent anybody monitoring your internet connections from learning what sites you visit.
Tor works with web browsers, instant messaging programs and many other TCP-based apps. But the various app protocols and associated programs can be coaxed into revealing information about the user, which is where Privoxy comes into the picture. Tor depends on Privoxy and its filtering capabilities to enhance privacy.
Privoxy
Begin by pulling Privoxy from your distro repositories, then head into your browser's advanced settings where you can change its proxy settings. Here just fill in 127.0.0.1 for the HTTP proxy, and specify 8118 as the port. That's all there's to it.
When you're done, start the Privoxy daemon with /etc/ init.d/privoxy start. You can now access Privoxy's interface from http://config.privoxy.org or http://p.p.
To hook up Privoxy with Tor, you first need to set up Tor's package repository. This is easily done by adding the following line to your Ubuntu or Debian installation:
deb http://deb.torproject.org/torproject.org main
Replace with the name for your distro, like karmic, or sid. Then add the GPG key used to sign the packages by running the following:
gpg --keyserver keys.gnupg.net --recv 886DDD89 gpg --export A3C4F0F979CAA22CDBA8 F512EE8CBC9E886DDD89 | sudo apt-key add -
If you use Yum, create a torproject.repo under /etc/ yum/repos.d with the following content:
[torproject]
name=Tor and Vidalia
enabled=1
autorefresh=0
baseurl=http://deb.torproject.org/torproject.org/rpm/
DISTRIBUTION/
type=rpm-md gpgcheck=1
gpgkey=http://deb.torproject.org/torproject.org/rpm/RPMGPG- KEY-torproject.org
Again replace DISTRIBUTION with the name of your Fedora or CentOS release, such as centos5 or fc13. Now fetch Tor via the package manager, which will also pull in additional packages like the Vidalia Tor GUI controller.
Make sure you don't install the Polipo web proxy app, since we are using Privoxy and the two might conflict because they operate on the same port.
The last step is to get Privoxy and Tor to talk to each other. For this just edit the Privoxy config file under /etc/privoxy and uncomment the following line:
# forward-socks4a / 127.0.0.1:9050
Also uncomment the following lines to make sure the local network is still reachable:
# forward 192.168.*.*/ .
# forward 10.*.*.*/ .
# forward 127.*.*.*/
Presto! Now all our internet traffic that passes through the Tor and Privoxy proxies is masked.

Ubuntu applets

On OMG Ubuntu I found this very nice guide for Gnome panmel applets:

read it here


Here is a copy:


The default desktop of Ubuntu 11.04 Natty Narwhal will no longer support  the traditional GNOME panel applets many of us have become accustomed to.
Supplanting them fully will be ‘Application Panel Indicators’. These new breed of notification area entries are designed to be consistent and unified in look and function, thus leading to a desktop more in tune with itself and with its users.
Just as with GNOME Applets you’re free to pick and choose which of these you use, install or run, so here’s a quick run down of the most popular ‘App indicators’ and ‘Indicator Applets’ presently available along with all the links/info you need to install them.
Note that for simplicities sake we’ve opted to not mention indicators that ship with Ubuntu by default – Tomboy, Transmission, etc.

Ubuntu One Indicator

By design Ubuntu One doesn’t come with a status area icon, something many users sorely miss.
Roman Yepishev did a bit more than moan about missing it, fashioning this gorgeous ‘Ubuntu One indicator-applet’. It lets you view and monitor your Ubuntu One accounts’ sync status with nothing more than a single click on on the panel icon.

More information on features, along with PPA installation instructions can be found by clicking this link.

Touchpad-indicator

Accidentally hitting the laptop track-pad is a pet peeve with a lot of users, but this tiny-indicator helps put paid to that.
image
Install via the official PPA:
sudo add-apt-repository ppa:lorenzo-carbonell/atareao
sudo apt-get update && sudo apt-get install touchpad-indicator

MyWeatherIndicator

My-weather-indicator is a panel-based weather forecast apple able to relay a surprisingly wide range of meteorological information.
image
It’s early days for the indicator but it gets a thumbs up from me for one reason: it’s simple. No endless menus or check-boxes to get up and running; just slap in your location and you’ll know the weather.
Install via the official PPA:
sudo add-apt-repository ppa:lorenzo-carbonell/atareao
sudo apt-get update && sudo apt-get install my-weather-indicator

CPUFreq

Monitoring CPU usage is a top priority for many users on portable devices. By limiting the clock speed of your laptop/netbook you can, in theory, extend your battery life a little lone. CPU-Freq offers all the functions of the standard GNOME Cpu-Freq applet but in indicator clothing.

The applet can be installed by running the following commands in a Terminal: -
sudo add-apt-repository ppa:anton-sudak/indicators
sudo apt-get update && sudo apt-get install indicator-cpufreq

Indicator-Workspaces

Switching workspaces via an indicator is an idea that, on paper, seems over-kill, particularly in light of other, faster methods.
And then I tried it.

Now installed by default in several Ubuntu-based distributions, this mini switcher is a lot more useful than many give it credit for.
Find install instructions here.

Indicator Keylock

Be alerted to when the caps lock, scroll lock or number lock keys are ‘on’ or ‘off’. ‘Piffle?’ you say? Although my keyboard does have a ‘caps lock’ light – I never remember to look at it so, for fellow unobservant folks out there, this is worth its salt.
Indicator Keylock applet
Installation instructions, along with a bit more rationale, can be found here.

Clipboard managers

Are you one of those people who copy and paste a lot? If so you may already use a clipboard manager to, well, manage your clipboard. With anticipation of Natty’s depreciation of familiar GNOME applets be sure to cast a mental CTRL+C over the following indicators replacements.

Pastie

‘Pastie’ looks and does what you’d expect it to. With a mono-icon and ‘Clean history’ button it sits as one of the best of its ilk available to Ubuntu users.

Installation instructions and a bit more information is in this post.

Diodon

A similarly purposed indicator is Diodon. Lacking a mono-panel icon, it does look out of place when using Ubuntu’s default theme. That said it’s a light and capable tool worthy of consideration.

Stable build PPA for Maverick users can be found here.

Clip It

An Indicator-based fork of clipboard manager ‘ParcelLite’, ClipIt boasts very little to differentiate itself from rivals. The lack of a ‘clean’ option within the menu list makes it the perfunctory third choice in this list.
Download can be found @ sourceforge.net/projects/gtkclipit/

USB Removal

Safely remove USB thumb drives, mounted SD Cards and more with ‘USB Safe Removal application indicator’ (Or Indicator-unmount’ for short ;) ). The tiny app doesn’t sing, it certainly doesn’t dance but it does do what it says on the tin: eject mounted drives.

Download and further information can be found here..

LookIt!

TinyGrab inspired screenshot tool ‘Lookit’ is a mini-marvel for us bloggers, many of whom are seemingly insatiable for ‘yet more’ screenshots to prop up our dubiously written texts.
As an app Lookit is neat, configurable, allows for quick capturing and uploading of screenshots and runs directly from the notification area. No extra windows, no more hassle.

The beta release of ‘LookIt’ can be downloaded in .deb from from the project page or installed from the testing PPA below in a few hours time.
  • sudo add-apt-repository ppa:lookit/testing
  • sudo apt-get update && sudo apt-get install lookit
The latest stable version can be installed using the Lookit stable PPA: -
  • sudo add-apt-repository ppa:lookit/ppa

Indicator-Virtualbox

We’ve covered this quick-launch applet for Virtualbox machine in depth recently. Suffice to say it’s nothing more than a glorified quick launch menu for your VirtualBox machines.
Indicator virtualbox for Ubuntu

This applet works in tandem with the tray based wallpaper changer DesktopNova. It’s easy to use and easy to install, making it a perfect app for impatient wallpaper lovers.

The DEB Packet is available via repository. Please keep in mind to never trust external repositories!  Even though I will never upload any shit to this repo I recomment the old scool way regardless: add the RSS to your favorite feed reader and fetch the package from the header of this website. The repository is signed (same goes for the packages, too) so you can be kind of “shure” that the stuff is what it is expected to be.

sudo wget -O - http://repository.mein-neues-blog.de:9000/PublicKey | sudo apt-key add -
echo "deb http://repository.mein-neues-blog.de:9000/ /" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get install xplanetFX

Stellarium troubles solved

In Stellarium, one of my favourites, sometimes the display doesn't work OK

Version 0.10.2

The landscapes sometimes don't appear properly. This is some problem with this file ~/.config/Trolltech.conf (~ means /home/yourname so it is a file in a hidden map in your home file. In Nautilus you can unhide files and maps by pressing CTRL H together)
You can delete the file and a new one is created when Stellarium is restarted. All should be working fine from now on.


version 0.10.4 and version 0.10.5
Also in these versions the landscapes don't appear properly. This is about a nummeric problem. It's solved this way:


1) Create a simple text file with an [ *.sh ] extension (script file). I personally created it here:
/home/USER/.stellarium/Stellarium.sh
2) Simply stick the command in the text file:
 

LC_NUMERIC=C stellarium
 

Save and close
IMPORTANT

make your script file executable in File/Properties/Permission, where you select:
[ Allow executing file as program ]
3) Enter in
[ System/Preferences/Maim Menu/Sciences/Stellarium/Properties/Command ]
and point to your script file. In my case: (replace USER with your ubuntu username)

 
[ /home/USER/.stellarium/Stellarium.sh ]


Look here to install version 0.10.5
