How to shutdown and reboot the Raspberry Pi

Raspberry Pi does not feature an power on/off button, if it's receiving power it's ON and if not OFF. However, it is required to do a graceful shutdown or reboot as to prevent any operating-system corruption. Rebooting and Shutting down Raspberry Pi can easily be achieved by using "sudo reboot" (sudo if not using the root account) and "sudo shutdown -hP now" at the terminal. These commands can also be used over SSH terminal if you are running your RasPi headless (without a screen attached) or remotely over network.

All-new PhoneTrans - Manage iPhone iPad Media & Apps in a Better Way

Surprisingly this fall we got three brand new Apple gadgets, the iPhone 5, iPod touch 5 and 'Renanoed' iPod nano 7. Before buying one or more of them, have you thought about how many Apple devices are already in your family? If you and your families have a bunch of iPhones, iPads and iPods, probably you'll get big headache to manage them upon one single computer.

The root cause of this inconvenience is iTunes, an application that takes on almost everything, e.g. iDevice media (and app) management, purchase, and playback jukebox, and much more. Apart from constant updates, slowness, source-consuming, complicated settings and limits, iTunes also leaves the media and app management part far away from desired. We have reviewed the best Apple iTunes alternative PhoneTrans earlier, well it got better and now features an brand new user-interface and supports synchronization of music, Apps, movies, music videos, TV shows, podcasts, ringtones and eBooks.

One frequently met situation is that Adding a single HD movie to iPad may take about half an hour and risk losing all apps along the way. Besides, iTunes will also fill up hard drive with tens of gigabytes of iOS apps that can easily be downloaded from Apple. Syncing apps frequently may also destroy folders and make apps disappear. Another problem is Managing multiple devices on one computer with no way to move music, movies back to PC hard drive.
