Terminal 101: Managing Disk Space

Every Monday, we'll show you how to do something new and simple with Apple's built-in command line application. You don't need any fancy software, or a knowledge of coding to do any of these. All you need is a keyboard to type 'em out!

Whether you've got limited space because you're running OS X on a tiny SSD, or you're just conscious about getting the most out of every byte you've paid for, you can use two Terminal commands to help you keep track of disk space usage. We’ll show you how to track down large files eating away at your disk space using these built-in tools.

MacTech, Southern Stars Using Social Media to Launch SkyCube Satellite Into Space

We all know that social media is a powerful force, but can it be used to launch a satellite into orbit? That's what MacTech magazine and Southern Stars are hoping as they seek donations to launch SkyCube into space next year.

MacTech and Southern Stars have jointly announced an ambitious project for "the world's first personal, interactive satellite mission" on Friday. Their goal is to use Kickstarter funding to get a satellite named SkyCube into space next year as part of a secondary payload on the SpaceX Falcon 9 rocket.

"We want to create a space exploration experience that everyone can be a part of," explains Tim DeBenedictis, founder of Southern Stars, a leading provider of mobile apps for amateur astronomers. "We are developing a nano-satellite, and mobile apps to go with it, as the focus for a global education and public outreach campaign."

The tiny SkyCube will allow people all over the world to participate in next year's launch by tweeting messages and even obtaining pictures of Earth from space. The satellite will also broadcast simple messages uploaded by sponsors including MacTech, who is the first corporate backer of the project.

"What attracted MacTech to support SkyCube was the prospect that anyone could be involved," said Neil Ticktin, Editor-in-Chief/Publisher of MacTech magazine. "MacTech has always been about bringing the community together, and SkyCube demonstrates the best of this. At MacTech Conference (October 17-19, 2012 in Los Angeles), we'll be doing some fun stuff around this project and giving the Apple technical community a great opportunity to be a part of history."

The SkyCube mobile app will be available for iOS via the App Store, with an Android version also available on Google Play; amateur astronomers can also tune in from any web browser. A basic sponsorship to participate in the mission is only $1, which allows the sponsor to tweet a single message into space.

For more information, visit the Kickstarter page to check out the variety of packages Southern Stars and MacTech have lined up for the event.

White Space Hopes to Bring Reliable Broadband Connectivity to UK's Rural Areas

By Nick Ruble MobilityTechzone Contributing Writer

It’s a well-known fact that broadband services are less available in rural areas, but with the digital dividend from television’s analog to digital transformation, there is a whole new horizon open for exploration. A newly implemented means of broadband delivery, dubbed “White Space”, is in its early stages of testing on the small Scottish Isle of Bute.

This new solution travels through the now-unused UHF band and is capable of delivering speeds upwards of 8Mbits/s – about the average rate of a DSL connection. Traditional hard-wired methods of delivery are impractical in remote areas due to the need for excessive resources.

The farther a cable line is stretched, the weaker the signal gets, which is clearly demonstrated by Bute’s average connection speed of less than 1Mbit/s. Chris Gibbs of BT, the company running the trials, stated, “Although it has the same characteristics as copper – the further you go the worse the signal gets – it goes a bit further, and that's the advantage”

BT warns that this new means of connectivity is still in its early days, but at the same time are seeing promising results. With the already blazing fast speeds of 4G networks though, one has to ask; will White Space really catch on? Sure, it may be the only means of Internet access in a great deal of rural areas, but will there even be enough consumers to support it?

The answers to these questions and many more will be made clear when pricing and conclusive test results are announced, but like BT said, things are looking very promising thus far.

New ideas and methods of broadband deployment are always surfacing, and BT’s White Space solution could very well prove effective. If so, businesses and consumers across the UK would surely benefit – Internet access is becoming a necessity in just about everyone’s lives, and those living in rural areas shouldn’t have to be an exception.
