Ubuntu 18.04 LTS will go back to using GNOME as the default desktop environment, instead of Unity.

In what comes as a big surprise for many, Mark Shuttleworh, the founder of Ubuntu and Canonical, explains on the Ubuntu Insights website that Canonical is ending their “investment in Unity8, the phone and convergence shell”.
Existing LTS releases will continue to be maintained, so Unity 7 should still see some bug fixes in the future. However, with Ubuntu 18.04 LTS (to be released in April, 2018), the default desktop environment will be GNOME.

While Mark doesn’t explicitly says “GNOME Shell”, I assume that’s what he means, especially since Unity 7 has been in maintenance mode for quite a few Ubuntu releases.

“I took the view that, if convergence was the future and we could deliver it as free software, that would be widely appreciated both in the free software community and in the technology industry, where there is substantial frustration with the existing, closed, alternatives available to manufacturers. I was wrong on both counts.
In the community, our efforts were seen fragmentation not innovation. And industry has not rallied to the possibility, instead taking a ‘better the devil you know’ approach to those form factors, or investing in home-grown platforms. What the Unity8 team has delivered so far is beautiful, usable and solid, but I respect that markets, and community, ultimately decide which products grow and which disappear”.

Pithos 1.3.0 was released recently and is now available in its official PPA, for Ubuntu 17.04, 16.10 and 16.04. The new version brings support for MPRIS playlist and tracklist interfaces, improved accessibility UI, and more.


Pithos is a Pandora Radio (only available in Australia, New Zealand and the United States) client that supports Pandora features such as love / ban / tired, allows creating, editing and switching between stations, and more.
The application integrates tightly with the desktop, providing notifications, MPRIS v2 support (it integrates with the Ubuntu Sound Menu / GNOME Shell, etc. ), media keys, can inhibit the screensaver and so on.

Pithos 1.3.0 includes a complete MPRIS implementation thanks to the addition of playlist and tracklist MPRIS interfaces.
With the GNOME Shell Media Player Indicator extension, Pithos exposes the current playlist and station list in the indicator (these need to be enabled in the extension settings):






This feature does not work with the Ubuntu Sound Menu due to an upstream bug.

Create Users and Manage Their Sudo Privileges on Ubuntu

create sudo user


The sudo command allows normal users to run programs which are only available to the root user. In this tutorial, we will show you how to create a system user and manage its sudo privileges on a Linux VPS running Ubuntu 16.04 as an operating system.

First of all, connect to your Linux server via SSH and add a new system user:

# adduser newuser

Feel free to replace newuser with the name of the system user you want to add. You will need to enter a password for your new user as well as you will need to enter some random user information. You can generate a strong password through the command line.

# adduser newuser
Adding user `newuser' ...
Adding new group `newuser' (1001) ...
Adding new user `newuser' (1001) with group `newuser' ...
Creating home directory `/home/newuser' ...
Copying files from `/etc/skel' ...
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for newuser
Enter the new value, or press ENTER for the default
        Full Name []: New User
        Room Number []: 101
        Work Phone []: 123456
        Home Phone []: 123456
        Other []:

Dell Most Powerful 15 and 17 Laptops Powered by Ubuntu Linux

After announcing earlier this year the release of the Dell Precision 5520 mobile workstation as the world’s thinnest and lightest 15” notebook powered by Ubuntu, Dell launches two new models for fans of the Linux-based operating system.

Originally scheduled to arrive during the month of March 2017, the Dell Precision 7520 and Dell Precision 7720 models are finally available for purchase, and Dell dubs them as the world’s most powerful 15-inch mobile workstations preloaded with the Ubuntu 16.04 LTS (Xenial Xerus) operating system.

Install Packages from Source

Most modern Linux distributions enjoy standard repositories that include most of the software you’ll need to successfully run your Linux server or desktop. Should a package come up missing, more than likely you’ll find a repository you can add, so that the installation can be managed with the built-in package manager. This should be considered a best practice. Why? Because it’s important for the integrity of the platform to ensure the package manager is aware of installed software. When that is the case, packages can easily be updated (to fix vulnerabilities and the like). Another reason to install from repositories is that dependencies are easily met. When installing from source, you can sometimes find yourself trapped in a convoluted dependency nightmare.

Fortunately, repositories have become so inclusive, that it is rare you will ever need to install a package by any other means. However, you may find, on occasion, a reason to install from source. Reasons could include:

  • A package that is not found in any repository
  • A package developed in-house
  • You need to install a package with custom dependencies or options

When you do have to install from source, there are certain things you will need to know. Let’s walk through the process of installing Audacity from source on Ubuntu 16.10 (with the help of build-dep). Although this can be easily installed from repositories, it serves as a fine illustration for installing from source.

First things first

Installing from source used to be very common and also quite simple. You would download the source file, unpack it (with either zip or tar), change into the newly created directory, and then issue the commands:

Test And Recover Your Passwords By Cracking Them


Hashcat is a robust password cracking tool that can help you recover lost passwords, audit password security, benchmark, or just figure out what data is stored in a hash.

There are a number of great password cracking utilities out there, but Hashcat is known for being efficient, powerful, and full featured. Hashcat makes use of GPUs to accelerate hash cracking. GPUs are much better and handling cryptographic work than CPUs are, and they can be utilized in much greater numbers than CPUs. Hashcat also supports a very wide range of popular hashes, to ensure that it can handle deciphering nearly any password.

Please note that misuse of this program can be illegal. Only test on systems that you own or have written permission to test on. Don’t share or post hashes or results publicly. Hashcat should be used for password recovery and professional security audits.

Getting Some Hashes

If you’re going to test out Hashcat’s hash cracking capabilities, you’re going to need some hashes to test with. Don’t do something crazy and start digging up encrypted user passwords on your computer or server. You can create some dummy ones for just this purpose.

How to Create a Wifi Hotspot in Ubuntu

How to Create a Wifi Hotspot in Ubuntu

For a long time on Windows, it has been possible to use a wireless networking adapter to share an Internet connection with other computers. Usually this is done by setting up a “hotspot,” or “ad-hoc” style network, broadcasted directly from the wireless networking adapter. It’s very easy to do, and it’s a killer feature that a lot of Windows users like.

On Linux, broadcasting a hotspot hasn’t always been easy. Until recently, users had to manually enter the command line, bridge adapters together, set up IPtables, etc. In newer versions of Ubuntu (and Network manager), however, making shareable connections via hotspots can be done as easily as it can be done on other operating systems.

The first step is to create a new wireless network. Go to the “Wireless Connection” menu, find “Edit connections” and select it. This brings up the “Network Connections” window. Create the new connection by clicking “Add.”
