5. Airdrop and Multipeer Connectivity

Hiedi Utley, Engin Kurutepe, Michael Ang, Josh Brown, Doron Katz, Cody Ray Bleeding Edge Press ePub

AirDrop is a technology first introduced by Apple in OS X 10.7 Lion. It enables Macs to easily share files. Sharing files between AirDrop capable machines is as easy as activating AirDrop in Finder and dragging the files onto the icon for the desired machine after the nearby computers are shown. AirDrop sharing magically works even if the machines don't have an Internet connection. It even works if the machines are not connected to the same WiFi access point, or to any access point for that matter.

AirDrop works by establishing an adhoc Wi-Fi connection between the participating Macs, thus removing the need for the Internet and an infrastructure wireless network.

Now, with iOS 7, Apple is bringing this technology to the world of iPhones and iPads. iDevices can share files and documents among each other as long as Wi-Fi and Bluetooth are both turned on (as of this writing, AirDrop on iOS and Mac is not compatible).

The BepBop app can send and receive PDF files over AirDrop. When you tap to open one of the PDF files listed in the table view in the "Direct Wireless Connectivity" section of the app, you will see an 'action' button at the top right corner of the screen. Tapping that button allows you to send the PDF document over various methods including AirDrop:

The Movement: Meet the Enemy

Matt Murdoch Treion Muller FranklinCovey Publishing ePub

We’ve tolerated and nurtured the webinar as it is for years. We’ve made some real advances and done some very cool things. But we still have a long way to go. We don’t believe that webinars can continue to evolve incrementally, like some single-celled amoeba waiting another million years to get closer to the edge of the ooze and start growing some legs.
And so we’re declaring war on bad webinars, and we want you to join us. We want you to join us in committing to KEEP doing the things that work and STOP doing the things that don’t work, that never worked…THAT NEVER WILL WORK.

Chapter 1 - Execute Priorities With Excellence

Stephen R. Covey, Robert Whitman and Breck England FranklinCovey RosettaBooks, LLC ePub

Winning on the flats is one thing—winning in the mountains is another.
Bob Whitman



In difficult times, winning performance depends on precise execution.

For the Tour de France, the mountains are the toughest challenge. This is the hardest part of the race where so much gets decided. Here the advantage goes not necessarily to the physically strongest team, but to the team that executes with the greatest precision.

Think about Lance Armstrong’s famous U.S. Postal Service and Discovery Channel teams that won the Tour de France seven times. In the mountains, the team became a “ruthlessly efficient machine.” Day after day they consistently paced themselves at the front of the pack through the punishing Alps and Pyrenées. According to one observer:

This is the hardest part of the race where so much gets decided.

George Hincapie, once a weak climber, now powered the peloton up the middle climbs of each stage. Floyd Landis would take the lead at the foot of the final mountain, setting a pace that splintered the field. Landis then handed off to Jose Azevedo, whose climbing pace was so fierce that only the top few riders in the world could keep up. By the time Armstrong rode to the front, he could focus on defeating the handful of rivals who remained.
