The Na'vi don't have eyebrows. While you could just paint your makeup on over your brows if you don't have prosthetic appliances to cover them, a neat trick is to take a giant glue stick (or the spirit gum) and go over your eyebrows with it, rubbing the stick in the opposite direction of eyebrow growth. Let it dry and then do it one or two more times (depending on how thick your brows are). With your brows flat against your skin with a layer of "glue skin" over them, you can have a nice, flat...
Those of you who have been a part of the Null Byte community for even a short while know that I sincerely and firmly believe that hacking is the most important skill set of the future.
Most of you already know that a zero-day exploit is an exploit that has not yet been revealed to the software vendor or the public.

Last year, Razer kicked off a new trend by building a smartphone from the ground up with mobile gamers in mind.

It's no secret that MoviePass is a shell of the service it once was. The primary $9.95/month plan for three movies each month is inconsistent and can change drastically depending on your location. Thankfully, MoviePass isn't the only movie ticket subscription service available. We've compared all the best plans on the market to help you find the one that's right for you.
AMC Theatres was never a fan of MoviePass and even predicted its unsustainability. After the struggling MoviePass turned off diehard fans with too many new restrictions to combat its cash problems, AMC stepped in to save the day with its AMC Stubs A-List subscription for cheaper movie tickets.

With the TSA's full-body scanners occupying a great deal of airports nationwide, the debate remains as to whether air travelers should continue to be subject to immoral security techniques and possible health risks due to the x-ray scanning devices.

We're thinking more and more about our digital privacy these days. When we first started using smartphones, we'd download apps with reckless abandon, allowing permissions lists as long as novels in order to play free games.
