Vim 8.1 is a minor release, a few new features have been added since Vim 8.0. The main new feature of Vim 8.1 is support for running a terminal in a Vim window, it sounds great for me.So I decide to install Vim 8.1 on my main System.

As we all know that Firefox 57 will rename to Firefox Quantum. It means the New version Firefox will use Quantum Engine instead the old one.Even throgh Firefox 57 is still in beta,but we can install it from PPA under Ubuntu.sudo add-apt-repository ppa:mozillateam/firefox-next sudo apt-get update sudo apt-get install firefox So here it is.
