Install apt-fast Download Accelerator in Ubuntu 12.04/11.10/10.04

apt-get command is a normal way to download and install packages and update system. apt-fast is a shellscript wrapper for apt-get that can drastically improve apt download times by downloading packages in parallel, with multiple connections per package. It uses axel or aria2c as a download manager.

Once you’ve setup apt-fast, you can use it like apt-get. To install a single package, make sure your database is up to date (apt-fast update), and run apt-fast install packagenamehere. Watch it download with incredible speed, and install your requested packages. To upgrade or dist-upgrade, do the same thing. Just use apt-fast dist-upgrade or apt-fast upgrade.

Install and set up apt-fast in Ubuntu:
apt-fast got an official PPA provides packages for Ubuntu 12.04, 11.10, 11.04, and 10.04. You can use a graphical way installing apt-fast from ppa:apt-fast/stable

Or, open up a terminal (Ctrl+Alt+T) window and just execute following commands:

sudo add-apt-repository ppa:apt-fast/stable
sudo apt-get update
sudo apt-get install apt-fast axel

After installation, configure apt-fast to use axel as download manager:

• edit the configuration file:

  sudo gedit /etc/apt-fast.conf

• remove # before following “_DOWNLOADER” line and save the file
  

  # axel:
  _DOWNLOADER=’cat /tmp/apt-fast.list | xargs -l1 axel -n ${_MAXNUM} -a’ # axel

Now, run this command and then you can use apt-fast as apt-get

sudo apt-fast update

How To Increase Your Internet Connection Speed in Linux

Open a terminal in Linux you can use the combo keys ( Ctrl )+( Alt )+( T )
Open a terminal for wireless enter iwconfig then hit enter. For wired eithernet enter ifconfig & hit enter.
This should display the hardware & location of = 
EX =

CODE: SELECT ALL

mi@Mint8-KDEX64 ~ $ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

eth2      IEEE 802.11  Nickname:""
          Access Point: Not-Associated
          Link Quality:5  Signal level:207  Noise level:166
          Rx invalid nwid:0  invalid crypt:0  invalid misc:0

mi@Mint8-KDEX64 ~ $

So here you can see that my wireless adaptor is located @ ( eth2 )
YOURS MAY BE DIFFERENT SUCH AS Wlan0 OR WLAN1, note the location, keep the terminal open.
Then were going to Navigate Open the file as root user with your text editor(gedit,kate,leafpad,Ect. whatever your text editor may be for the relevant desktop version you are using ),The text file we are Going to open is /etc/rc.local
In the open terminal input, or copy & paste this code:


For Gnome
CODE: SELECT ALL

sudo gedit /etc/rc.local

For KDE
CODE: SELECT ALL

sudo kate /etc/rc.local

For LXDE
CODE: SELECT ALL

sudo leafpad /etc/rc.local

Enter your password.(The cursor will not show you entering your password.) This should open the rc.local file as root in the text editor.
Add this exactly. to the end of the list replacing ( wlan0 ) with whatever is in your connection readout previously in the terminal you opened.

CODE: SELECT ALL

iwconfig wlan0 rate 54M

At The End your text file should look like this =





# By default this script does nothing.
iwconfig wlan0 rate 54M
exit 0


Now save the file ( from the text editor drop down menu ) & close the Text editor. Now Close the Terminal.
By adding this to the end of the rc.local file, every time your computer connects to the Internet,It looks for the maximum speed that your connection offers.
Now You Must Reboot your Computer.
This works on all four of my systems I have modified, so far giving me the same speed that I get in Win.
I hope this works as well for you, Comments & suggestions are welcome, Have a Good Day,

How to Make Firefox Faster on Linux Mint

Before making any changes, please make a backup of .mozilla/firefox/--------.default/prefs.js for your own safety. prefs.js is a file that stores all of your history and bookmarks from Firefox. 

•  First open Firefox. 

• Type "about:config" (without quotes) in the Firefox address bar and then click "Enter". This command opens a configuration page that allows the user to change advanced system settings in Firefox.

• Speed up page loading/rendering time in Firefox. Right-click anywhere in the "about:config" window, click on "New" and then select "String". Name the string "nglayout.initialpaint.delay" (without quotes). Enter a value of "0" and then click "OK". This tweak decreases the amount of time Firefox waits to render a page from 250 milliseconds to zero. Make the same process and name the string "content.notify.interval" and enter a value of "0".

• Force Firefox to release reserved system RAM when the browser is minimized. Right-click anywhere in the "about:config" window, click on "New" and then select "Boolean". Name the entry "config.trim_on_minimize" (without quotes). Change the value to "True" and then click "OK". This setting forces Firefox to only reserve about 10 MB of system memory while minimized.

• Normally Firefox only sends one or two tunnels to the website. However, the more tunnels you use the faster you go. To change this, type in filter bar "network.http.pipelining.maxrequests" and change the value to "150".

• Attention: The more tunnels you use, the more bandwidth you use, meaning you could use as tunnels as you want but that would probably kill the sites bandwidth if everyone did that. 150 is a very good value.

• Type "network.http.pipelining" in filter bar, and set it to "True" by double clicking it.

• Type "network.http.proxy.pipelining" in filter bar, and set it to "True" by double clicking it.

Monitor System Resources in Ubuntu 12.04 LTS

This tutorial shows how to monitor your Ubuntu system resources such as usage of processor, memory, network, hard disk and also cpu/motherboard temperature, cpu fan speed.
There’s a good system load indicator for Ubuntu monitoring cpu usage, cache, memory, network, etc. And psensor is a gtk+ application monitoring temperatures and fan speeds.

1. Install system load indicator

Open up a terminal (Ctrl+Alt+T) and install it from ppa:indicator-multiload/stable-daily. You can use graphical way adding ppa

sudo add-apt-repository ppa:indicator-multiload/stable-daily
sudo apt-get update
sudo apt-get install indicator-multiload

 
2. Install psensor to monitor temperatures and fan speeds

First install lm-sensor, and start detect hardware sensors:

sudo apt-get install lm-sensors sudo sensors-detect

Install Psensor from this ppa:jfi/ppa

sudo apt-add-repository ppa:jfi/ppa
sudo apt-get update
sudo apt-get install psensor

 
3. Launch startup applications from the dash, add the two indicator as auto-start at login.
in command area:

• system load monitor use indicator-multiload
• psensor use psensor

BackBox Linux for Debian/Ubuntu

Ubuntu Natty 

You can update your system by adding ppa:backbox/two to your system's software sources.

Step 1 - Open a terminal and enter: 

 sudo add-apt-repository ppa:backbox/two 

Your system will now fetch the PPA's key. This enables your Ubuntu system to verify that the packages in the PPA have not been interfered with since they were built. 

Step 2 - 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

Now you're ready to start installing software!

  

Other systems 

This PPA also can be added to your system manually by copying the lines below and adding them to your system's software sources.

deb http://ppa.launchpad.net/backbox/two/ubuntu natty main

deb-src http://ppa.launchpad.net/backbox/two/ubuntu natty main

Step 1 - Open a terminal and type: 

sudo nano /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 2 - 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 78A7ABE1

This will now pull down the PPA's key and add it to your system. 

Step 3 - 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

Now you're ready to start installing software!

 

Speed up your Ubuntu 12.04 with preload

Preload is nice little application that could make your linux system a lot faster. Preload is an adaptive readahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times.

Preload packages are available for almost all linux distributions. And it is available by default in the Synaptic Package Manager and Ubuntu Software Center in Ubuntu. Alternatively, you can install it via Terminal. Type this command

 sudo apt-get install preload

Thats it. Preload will run silently in the background. If you want to further tweak Preload, conf file is available at /etc/preload.conf.

Note that installing preload will not make your system boot faster and that preload is a daemon that runs with root priviledges.

And see the difference.

BackBox Linux

BackBox is a Linux distribution based on Ubuntu. It has been developed to perform penetration tests and security assessments. Designed to be fast, easy to use and provide a minimal yet complete desktop environment, thanks to its own software repositories, always being updated to the latest stable version of the most used and best known ethical hacking tools.

How To Change Blogger Icon

here are the steps to do it:

1. Prepare an image, can be JPG or PNG format. I suggest PNG format because its size will be smaller by a 4:1 ratio. It means that a 10 Kb JPG image will be a 2.5 Kb in PNG format. Also make sure the size is small like 20 x 20 pixels or less, so the file will be smaller in size and won't make your blog loads slower.

If it's difficult for you to edit a small image, you can make a bigger one first, like 200 x 200 pixels or more, and after finish, you can skew it smaller. Microsoft Paint can do it for you easily.

2. Upload the image to an image hosting service, like the free PhotoBucket. Then, obtain the direct link to your image for the next step. You can use another image hosting service if you like, just remember to get the direct link.

3. Add this bold tags to your template. To access it, click "edit html" in "layout" section. Put them in head section, between "title" tag and "b:skin" tag. If you face difficulties in finding the tag, just use the find tool in your browser. In Mozilla Firefox, the shortcut is ctrl+f. If you use another browsers, apply with adaptation.

<title><data:blog.pagetitle>
<link href='put the direct URL of your image here' rel='shortcut icon' type='image/vnd.microsoft.icon'/>
<b:skin>

Save and done! Visit your blog, open a few tab, and you should see your new icon there.
