Most Useful Ubuntu Utilities

8 Most Useful Ubuntu Utilities To Make Your Experience Better

          If you are a beginner in Ubuntu or an expert, it doesn’t matter, what we want is just to enrich your Ubuntu experience by every possible means. Ubuntu has much more to offer than initially it seems. You can refine the look of your Unity desktop, tweak the desktop to perform system maintenance and whatever else you wish to do. There are a huge array of utilities which can customise Ubuntu in a way that it meets all your needs. Here are eight best utilities or apps to make your Ubuntu experience much and much better.

1. Unity Tweak Tool:
       Unity Tweak Tool is the best example of customisation options on Ubuntu as it offers a set of system tweaks for both Ubuntu and Unity desktop. It’s packed with full of switches and control and you can configure Unity as however you wish. You can change the GTK theme and icon set without much hassle, adjust launcher size, add or remove workspaces and more. Unity Tweak Tool is available for free at the Software Center.

2. Disk Utility:
       This is an awesome utility application which allows easy management of any disk drive in the computer. Users can format, partition and erase hard drives easily and also clone, copy and backup from one disk to another one. It’s very helpful for a Ubuntu novice who is not very aware of the formatting and partition requirements in the operating system.

3. Proprietary Drivers:
       You must install proprietary drivers which allow hardware to function in a better way than open source drivers, which come with Ubuntu. It depends on your system’s hardware, if the drivers can be installed or not. The most common types of hardware which have these drivers available are AMD and NVIDIA graphics cards and Broadcom wireless chipsets. The drivers can be found at Software & Updates utility.

4. Graphical Firewall Config Utility:
          Install graphical firewall configuration utility to enable and configure a firewall for your Ubuntu system. Linux is usually immune to viruses but hackers can gain remote access to the systems if there is no firewall which protects network ports. Run the command: sudo apt-get install gufw and configure firewall.

5. WinFF: GUI for FFMPEG:
      It provides graphical user interface or GUI for FFmpeg. It also helps convert a video file to any format and WinFF can convert multiple files in multiple formats at one time. There are also a variety of preset conversion settings for common formats and devices in this package.

6. Unity Privacy Indicator:
           Privacy is a big issue and Privacy Indicator is a useful tool to help you stay informed about which files, folders and services are getting accessed and logged in your Ubuntu desktop. If you click on the ‘eye’ icon, you can enable the privacy settings on your system.

7. System Load Indicator:
       If you want to keep a tab on apps and your hardware status, then it’s an easy job on Linux. There is  no dearth of mediums through which you can monitor CPU usage, network traffic or GPU temperature. System Load Indicator is available from the Ubuntu Software Center which has a host of configuration options.

8. Disk Space Visualiser:
         In this era of hard drives which have huge storage options, we don’t worry much about disk space and all. But if there is smaller SSD and multiple partitions are run and a virtual machine is worked upon with a fixed size virtual disk, then freeing up disk space might become a huge requirement. GNOME Disk Space Visualiser, which comes as default in Ubuntu, is very useful for locating hidden logs, cache files and media files.

Top 10 Things To Do After Installing Fedora 21

     Several advance changes have been made to the latest version of Fedora.Following steps will help you in configuring a basic working system based on Fedora 21. This OS supports lots of applications and users can also start working as soon as Fedora is booted. 




Here are ten things which you need to do after installing Fedora 21:

1. Run command and configure GNOME Shell interface:
First make sure that you are using the latest updates from Fedora 21 repositories through this command:

$ sudo yum update.

Then configure default GNOME Shell. Use the Gnome Tweak Tool and to install run this command: 

$ sudo yum install gnome-tweak-tool. 

Open “Gnome Tweak Tool” from the applications menu, and configure the GUI options easily. You can also browse available tabs to see the available options.

2. Configure keyboard shortcuts:
There are several pre-configured shortcuts which are available with GNOME 3.14. There are some additional shortcuts too which might prove helpful for you. Search ‘keyboard’ in overview, open keyboard app and click on shortcuts tab. You can configure the existing shortcuts and you can also make additional shortcuts too by selecting custom shortcut from the bottom of the list.
 Click on + button and add the shortcut name as well as the command.

3. Install extra repositories:
The official repository of Fedora has not much software as there are patent and licensing issues. That’s why third party repositories are used just like other Linux based operating systems. Add RPMFusion repository to install applications and there are two repositories within RPMFusion. Enable the free repository and then that one which is not free. Install both the repositories.

4. Install Gnome Shell extensions:
After setting up Fedora 21 you have to include extensions. They are useful for users as these extensions will modify the GNOME Shell interface as per user requirements. Install the extensions via ‘Gnome Shell Extensions’ website. This is an official website of the Gnome project. Enter the website and choose the extensions you want. Install them with a single click only.

5. Install multimedia codecs:
Fedora doesn’t offer proprietary multimedia codecs which are important for playing media files. RPMFusion repositories have these codecs. After installing these repositories, you can install the necessary multimedia codecs through this command: 

$ sudo yum -y install gstreamer1-libav gstreamer1-plugins-bad-free-extras gstreamer1-plugins-bad-freeworld gstreamer1-plugsins-base-tools gstreamer1-plugins-good-extras gstreamer1-plugins-ugly gstreamer1-plugins-bad-free gstreamer1-plugins-good gstreamer1-plugins-base
6. Install VLC:
VLC is popular as it can play any video format. It also converts media formats and you can also extract audio from video files. It can also play online videos from YouTube. Install VLC by this command: 

$ sudo yum install vlc

 It can also be found in the RPMFusion repositories.

7. Install Yum fastest mirror plugin:
If you have a slow Internet connection then this plug-in can be really helpful. It automatically selects nearest mirror server available and it speeds up downloading packages process. Run this command to install it:

 $ sudo yum install yum-plugin-fastestmirror.

8. Install Flash Player:
Adobe flash player is the most popular one to view flash content. It’s a closed-source content and that’s why it’s not packed by Fedora officially. You can use the following command to add Adobe Flash Player repository to Fedora.

## Adobe Repository 32-bit x86 ##
 
$ sudo rpm -ivh http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm
 
$ sudo rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux

## Adobe Repository 64-bit x86_64 ## 
$ sudo rpm -ivh http://linuxdownload.adobe.com/adobe-release/
adobe-release-x86_64-1.0-1.noarch.rpm  

$ sudo rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux

Then install the flash player by running: 

$ sudo yum install flash-plugin nspluginwrapper alsa-plugins-pulseaudio libcurl

9. Install Chrome browser:
Gnome’s Epiphany has been replaced by Firefox in Fedora 21. If you want Google Chrome you can install it by downloading the binaries from the respective websites. From the Chrome download page, get the .rpm binaries as per your system’s requirement. Double click on the binaries or right click and choose ‘Open with Software Install”. Follow the given instructions there.

10. Install other desktop environments:
Some famous desktop environments such as Mate, KDE, XFCE, LXDE, etc.. are available for download from the official repositories for Fedora 21. To install Mate desktop run: $ sudo yum install @mate-desktop. To install KDE desktop run: 

$ sudo yum install @kde-desktop. 

To install XFCE desktop: 
$ sudo yum install @xfce-desktop. 

To install LXDE desktop run: 
$ sudo yum install @lxde-desktop. 

To install Cinnamon desktop run: 
$ sudo yum install @cinnamon-desktop.

The entire Internet may crash on June 30.......

 Internet may crash on June 30.......

         So here’s something interesting, 2015 is going to be a little longer than other years, quite literally, and we do mean little. In order to account for the slowing down of the Earth’s rotation, scientists have added one measly second to the calendar. Doesn’t make a difference right? Google thinks it does. Apparently, the addition of a second can break the Internet. So, Google is reportedly taking preemptive action for the same.

          

 The extra second will be added to the calendar on June 30, precisely at 11.59.60. How ? Well, clocks will stand still for an entire second in order to add the time. Even though hardly anyone will realise it, the day will have 86,401 seconds instead of 86,400 seconds. This will have consequences for the Internet and computers at large. This had happened back in 2012, when websites like LinkedIn, Reddit and Yelp had gone down. The reason for the same is that the extra second cause computers to malfunction as more and more computers sync with atomic clocks today, because of which, even the difference of one second could cause them to malfunction.
       Further, Google has reportedly figured out how to prevent websites from crashing during this time. The search giant will be adding a millisecond to its system clocks gradually, instead of pausing for a second on the day. As a result, the computers will be corrected over time and won’t have to count the same second twice. Let's hope it works
