In short: In this guide, geared to new users of Ubuntu, I will explain how to change the default applications.

Install, for example,  VLC media player is, for me, one of the first things to do after installing Ubuntu 16.04 Xenial Xerus . Then it imposed VLC to make it the default application, as' doing every time I open a video it will start with my favorite media player.

A new Ubuntu user must be able to set all the applications you prefer to open files, this tutorial will explain 'how to proceed.

Change the default app in Ubuntu

The two methods that I will show you 'later are valid on Ubuntu 12.04, Ubuntu 14.04 and, of course, on Ubuntu 16.04. You can follow one of two paths:

  1. system settings
  2. right click menu

1) System settings

Go to the Unity Dash and search your system settings ' System Settings ':


Once in System Settings , click on 'Details option':


After clicking on details, in the left panel, select the 'Default Applications'. You'll see the option to change the default app on the right panel.


As you can see there are only a few applications that can be changed here. You can change the default settings for the web browser, email client, for the calendar, for music, for video and photos. And other applications?

Do not worry, for the other applications you need to go to method two.

2) Right-Click Menu

If you've used Windows should be at the current option ' open with ' that allows you just to open a file with a program of your choice in the list of eligible candidates. There is also something very similar in Ubuntu.

Double click the file type for which you want to change the application that opens it by default and open " property " or " properties ":


Then go in the submenu 'Open with' to select the application to use by default:


Done! All in all the procedure is simple or not?

I hope that the procedure will be proved useful, if you have doubts or questions you can leave a comment in the box below!

Unity 8 will not be the destkop environment by default in Ubuntu 16.10 Yakkety Yak according to the team development   but will be available in a session alternative.


After the release of Ubuntu 16.04 with still aboard Unity 7 , many hoped that the next version of the operating system Canonical would embrace the most modern and innovative Unity 8 along with the display server Mir , relegating their predecessor in a well-deserved retirement.

Unfortunately, the team development has denied the rumors about it during the opening of ' Ubuntu Online Summit which is taking place this week through a series of Google Hangouts , Ubuntu 16.10 will still Unity 7 as a desktop environment by default.

However, all is not lost for those who are fed up of waiting. Unity 8 and Mir will still be available as alternatives sessions from the screen login , allowing everyone to try it.

This move indicates as Canonical is still uncertain about the stability of the new interface developed by them and he did not feel the promise that the project will reach a  mature enough to replace Unity 7  in less than six months. While on a few devices specific as tablets and phones you can weed out bugs and problems of compatibility in each case, the most diverse market PC is a very different fish to fry.

What to expect from Unity 8 Yakkety Yak?

Despite the reluctance to affidarvisi completely, Canonical still has scheduled several objectives that aims to achieve by October to bring Unity 8 to its final release.

First there will be the feature parity with Unity 7 , very significant achievement that involves improving the management of  monitor multiple, more windows in desktop mode and other news.

In addition, Canonical is proposed many changes  including:

  • The porting of 'Ubuntu UI Toolkit' from QML to C++
  • The integration of driver support Vulkan/Khronos in Mir
  • Add support to global menu in applications X of Unity 8
  • And in general the various adjustments to the experience of the desktop " converged " who aim for years.

Google may unveil its next Nexus device this month

Good news coming this month, the press event that Google invites to could see it unveil its next Nexus device, and other things from Google.
On September 29th the media are on an appointment to “a morning conversation about some new treat from Google”
Googlethis will be the first major event with Sundar Pichai as the CEO of Google.
We know that Google isn’t always predicable, but now a lot of people say that the new Google hardware is coming.
Earlier this month CNET said that a Nexus launch was planned for the 29th, and there ‘s been speculation that Google has tapped both LG and Huawei to build different sized phones under its Nexus brand.  
The Nexus devices runs with pure form of android and is optimized for Google’s mobile software and it is worth mentioning that CNET also said that the company announced the name of its next version of Android…”Marshmallow”.
The Nexus devices are also usually fairly inexpensive, but Google doesn’t manufacture the phones itself since it  employs companies such as LG to manufacture its devices,  where LG previously created the Nexus 4 and Nexus 5 phones .
A growing force in the global smartphone race Huawei — hasn’t ever worked on the project, but It’s speculated that LG is working on a regular sized smartphone, with Huawei contracted to develop a larger handset.
This news would be an interesting so this device would be an interesting development that fits with trends in the market. Both Samsung and Apple have released ‘little’ and ‘large’ devices to suit different tastes, Galaxy Note 5 and Galaxy S6 Edge Plus from Samsung  ,  iPhone 6S and iPhone 6S Plus from Apple have released and it seems like a strategy that others are embracing too.

That is not all, since 9to5Google reported last week that Chromecast 2.0 will land later this month with a number of improvements such as faster WiFi connectivity, faster playing, multi-room support and improved audio feedback.

Let’s wait to the end of this month to see what’s in a quiver of Pichai.

Transparent solar-powered battery the Iron Man’s transparent smartphones may become reality sooner

You may unbelieving this but it might become reality sooner , unusual type of battery that not only transparent, but it can also charge via solar power. This technology could be used in a lot of future products like a smart office and maybe home windows, we can make the windows let the sun’s light pass through them and in the same time it can recharge and store energy.
This battery developed by team of researchers at Kogakuin University,  this battery contains the same chemical compounds that make any battery work, it is not entirely transparent, the light transmittance is about 60% when full charge state, and when the battery exposed to sunlight, the battery becomes slightly tinted, transmitting 30% less light –but it’s still transparent.
To allow light to pass through the battery the team of scientists shrink down the electrodes, all the way down to around 80-90 nano-meter.
The work on this battery take from the team about four years since a team of researchers at Stanford come up with the concept of a transparent battery .
From two years ago the researchers unveiled a nearly transparent prototype charged with separate solar panel, then they began on integrating solar charging power into the battery.
The technology now close to becoming in use, but it’s not clear how long it will take until it’ll be used in commercial products.

This image showing the battery.

First you need disconnect from the internet, this is done, we start the terminal and type:

For Ubuntu
sudo gedit /etc/resolv.conf
For Kubuntu, Xubuntu, Lubuntu
sudo nano /etc/resolv.conf
And insert as shown below:
# Generated by NetworkManager
Then save (if we use nano we have to press CTRL+X then S)
and try to connect through our browser, and if we need to navigate to lock the configuration and to do that, we finish the connection and terminal type:
sudo chattr +i /etc/resolv.conf
Now we locked configuration and Network Manager can not modify it and then we can connect without problems.
