Preview iOS 7 On Your iPhone & iPod Touch Without Installing the Buggy Beta
Of course the best way to preview iOS 7 would be to install the beta, but let’s face it, that beta is buggy, incomplete, and besides, it requires a developer account to use, which makes it inaccessible to the vast majority of people. So what’s the next best thing to preview the new iOS without installing the beta? Viewing full-sized, full-screened videos and screen shots directly on your iPhone or iPod touch. This gives you an excellent idea of how iOS 7 will look on your device, and with the videos, it also gives a good preview of how certain aspects will behave. This goes far beyond just viewing feature screen shots and visual comparisons between iOS 7 and iOS 6, and it really is the next best thing to just installing the beta, but without the hassles.
iOS 7 brings a significant user interface overhaul to Apple’s mobile devices, and though it’s best to be experienced and used first hand, 
Apple has yet to provide an official list of OS X 10.9 compatible Macs, but as we 
Need to securely delete a file, group of files, or an entire directory, insuring that it’s quite literally never recoverable by any known possible means? You can do this easily from the command line with the help of an incredibly powerful tool called srm. srm, as you may have guessed, stands for ‘secure removal’, and is a secure version of the commonly used ‘rm’ command that exists in virtually every flavor of unix, Mac OS X included. Be advised this utility is not for everyone and certainly not for novice users, srm should be considered an advanced tool, and it’s best used by those who are comfortable with the command line and understand the data repercussions of secure delete functions.
Though most of us are accustomed to the default QWERTY keyboard layout, iOS does provide options to toggle between QWERTY, AZERTY, and QWERTZ. The latter two options are generally used in Europe, but you can enable them on any iPad or iPhone regardless of which region you’re in, the only requirement is that a Latin alphabet keyboard is the default. These new software layouts work whether the keyboard is docked or in the 
Mac OS X includes an excellent command line network utility called “nettop” that allows users to monitor all network activity, traffic, and routes from a Mac to the outside world, both through local (LAN) and wide area (WAN) connections. If you’re unfamiliar with networking tools like this, you can think of nettop as a network centric task manager, displaying active networking connections, sockets and routes, their respective names and process id, the state of the connection and whether the connection is established, waiting, or listening, and information about individual process data transfer. It’s a bit like the standard ‘top’ and ‘htop’ commands which show process and resource information, but rather than showing CPU and RAM usage, it will show live network transfer information like packets sent and received, packet size, and total data transferred.
Have you ever noticed how some apps will have information pulled from your iOS Contacts list, like peoples names, numbers, and contact information? Or, contrarily, how some apps should have access to your address book, but don’t, and are then feature limited? Though this happens by choice, it’s fairly easy to overlook these settings during initial setup of many apps, or to forget which of the “Allow” or “Don’t Allow” setting you chose. Fortunately, this is very easy to see, and change in either direction.
