LYRICS TO LIVE BY: Artists Artists A Father Who Creatively Captures His Kids (20 photos) If there was a prize that could be given out to the most creative father, I'd hope that it was awarded to Jason Lee. A wedding photographer by day, he's used to capturing some of the most important moments in a couple's lives. As a longtime fan of Jason's photos on Flickr however, I think the real magic happens when he turns the camera onto his daughters. Sure, his children are adorably cute in their own right, but that's not what makes his photos so interesting. I was able to get in touch with Jason to ask him a few questions. Q: How did you get into photography? Q: How do you come up with such creative photos of your daughters? Q: How has being on Flickr helped you with your business? Q: Any inspirational stories you'd like to share? Q: Do you have any advice for aspiring photographers? Q: Any quotes you live by? Thanks for the interview, Jason, and for letting us share in your fatherhood experience. Jason Lee's website

Stogie Review Authorama - Public Domain Books Future Military Guns - Best High Tech Weapons 1 | SCAR-Light The effort to replace the M-16 rifle, as well as its more compact variant, the M4, has been a long, epic and largely tragic tale. One attempt would have created a modular weapon system, called the Objective Individual Combat Weapon (OICW), with an integrated grenade launcher and laser-rangefinder. That all-in-one system was scrapped because of excessive weight, and subsequent attempts to salvage the core of that weapon—the XM8 assault rifle—have also failed, highlighting some of the worst aspects of the weapons procurement process. Fed up with the rest of military's inability to replace the M-16 and M4, and apparently uninterested in an OICW-type multipurpose weapon, the Special Operations Command (SOCOM) held a competition for a new assault rifle, to be deployed with special forces personnel. This is precision-guided munitions for infantry, with the goal of negating nearly any kind of cover a target could find, particularly in urban environments. 4 | Corner Shot Launcher
How to Build the Ultimate Survival Shotgun As a Survival and Preparedness instructor, I take my line of work very serious – sometimes too serious. Occasionally, though, I like to take on survival projects that are just down right fun. This article highlights one of those projects. I’m fortunate in that I’ve been able to turn my passion into my profession – this being the study of Survival and Preparedness. Ultimately your survival needs fall into 5 main categories. Every survival kit must include contents that directly or indirectly meet these 5 basic survival needs.
Short Film of the Day: Stuxnet: Anatomy of a Computer Virus Why Watch? Because we should challenge how we define a film. Most of the shorts featured in this column are either easy to spot as stories or completely experimental. Even when a documentary short is in the spotlight, it tells a clear tale of people doing things. This short, is none of those things. Stuxnet: Anatomy of a Computer Virus is an informational film made entirely of voice over narration and motion graphics. It’s beautiful, compelling, and it does tell a story, but it’s nothing like most short films. What does it cost? Check out Stuxnet: Anatomy of a Computer Virus for yourself: Trust us.
