Every GNOME Shell user will visit the official GNOME Shell Extensions website at least once. And if those users do so this weekend they’ll notice a small difference as the GNOME Shell Extensions website is sporting a minor redesign.

Ask yourself why do you seek a Linux operating system with high performance in terms of security and test one of those Linux OS proposed in the link above.

It’s the perfect nightmare and everyone do all his best to avoid it but sooner or later it happens.
Loosing data from a hard disk or a USB device is more common than you can image and everyone has experienced it!
Windows has different commercial solutions available to recover data and partitions but, if you use Linux, you need something different.
The best solution I found for Linux is an old but current article by Lifehacker.au that I strongly recommend if you are experiencing this kind of problems and want to solve them.
“If your computer having problems or lags while using Windows operating systems, you’ll discover some fast and lightweight OS in this article. There is another post where we discussed best alternative operating systems that are not specifically for old PC’s”
Are you looking for a up-to-date Linux Distro to use that old laptop you have in the dust in the far corner of your garage? It could not be so easy to find the best Linux Distro to install on it but howtouselinux.net did some great twests for all us:
The review is really well-done and the graphic display of results let you to quickly choose what is the best Distro candidate for your laptop depending on hardware, your tastes and the final use you want to give to your laptop.
In my experience the howtouselinux.net review let me to save a lot of time because I was able to focus my tersts just on the two Distros that seemed to have the right prerequisites for my old eeepc 900: Peppermint OS and Macpup. Recommended!
Also if you use OpenDNS to improve your standard of privacy, you are not protected by “last mile” dangers but you can boost your security installing DNScrypt on your digital device. DNScrypt “works by encrypting all DNS traffic between the user and OpenDNS, preventing any spying, spoofing or man-in-the-middle attacks”.
DNScrypt “is a protocol that authenticates communications between a DNS client and a DNS resolver” and it “is not a replacement for a VPN, as it only authenticates DNS traffic, and doesn’t prevent “DNS leaks”, or third-party DNS resolvers from logging your activity”.
For this reason you have to be conscious that DNScrpt is just a -very good- improvement of your privacy but not the definitive solution to all your privacy concerns.
DNScrypt is so versatile that you can install it on every kind of device you prefer. In fact it is possible to download DNScrypt for servers, IOS, OSX, Android, Windows and Linux computers (DNScrypt-proxy version). Obviously the installation and setup will vary a little depending the OS you installed on your device.

Here we are talking about DNScrypt installation on Ubuntu.
For this purpose I suggest to use the Terminal that allows you to install DNScrypt i just 3 steps:
sudo add-apt-repository ppa:anton+/dnscrypt
sudo apt-get update
sudo apt-get install dnscrypt-proxy
Last but not least, you need to interface the Internet traffic of your computer through the DNScrypt-proxy. For this reason you have to Edit your Network Configuration and add the address 127.0.0.2 to the “DNS Servers” line as for the below screenshot:
Now you can start DNScrypt just typing:
sudo dnscrypt-proxy -R opendns -a 127.0.0.2:53 -u okturtles
Where, in my specific case, okturtles is the name of the remote DNS resolver I decided to use. I chose that specific risolver from the list I found into into my computer after DNScrypt-proxy installation:
/usr/share/dnscrypt-proxy/dnscrypt-resolvers.csv
As usual in similar situations, you may want to spend another couple of minutes to configure your computer to start DNScrypt at the computer boot. Open the Session and Startup manager through the desktop Dash and Add this specific command to the Application Autostart menu:
sudo dnscrypt-proxy -R opendns -a 127.0.0.2:53 -u dnscrypt
Wireless energy transmission for remote charging is one of the most strategic key factor for the development of a new generation of tech devices in the near future. Few years ago some futuristic thinkers forecasted the possibility of wireless energy transmission between far places. In particular the academic community was interested in energy transmission between the planet earth and orbiting satellites equipped with solar power stations.
