Updating ubuntu 7 04

Before doing anything else, log in to your system, and add Ondřej's PPA to the system's Apt sources: to execute PHP code.

We installed Ubuntu Touch 14.04 on our own hardware to see what those tablets will be like.

We don’t recommend installing this yourself, as it’s still not a polished, complete experience.

We’re using “Ubuntu Touch” as shorthand here — apparently this project’s new name is “Ubuntu For Devices.” Ubuntu’s touch interface is all about edge swipes and hidden interface elements — it has a lot in common with Windows 8, actually.

You’ll see the welcome screen when you boot up or unlock a Ubuntu tablet or phone.

PHP 7, which was released on December 3, 2015, promises substantial speed improvements over previous versions of the language, along with new features like scalar type hinting.

This guide explains how to quickly upgrade an Apache or Nginx web server running PHP 5.x (any release) to PHP 7.

Warning: As with most major-version language releases, it's best to wait a little while before switching to PHP 7 in production.

In the meanwhile, it's a good time to test your applications for compatibility with the new release, perform benchmarks, and familiarize yourself with new language features.

If you're running any services or applications with active users, it is safest to first test this process in a staging environment. A Personal Package Archive, or PPA, is an Apt repository hosted on Launchpad.

PPAs allow third-party developers to build and distribute packages for Ubuntu outside of the official channels.

They're often useful sources of beta software, modified builds, and backports to older releases of the operating system.

Ondřej Surý maintains the PHP packages for Debian, and offers a PPA for PHP 7.0 on Ubuntu.
