Developers creating login systems know better than to store passwords in plain text, usually storing hashes of a password to prevent storing the credentials in a way a hacker could steal. Due to the way hashes work, not all are created equal. Some are more vulnerable than others, and a little Python could be used to brute-force any weak hashes to get the passwords they were created from.
Continuing our series on building a dynamic user interface for the HoloLens, this guide will show how to rotate the objects that we already created and moved and scaled in previous lessons.
To promote Star Wars: The Last Jedi, Disney and Lucasfilm released virtual porgs into the wilds of Snapchat via a Sponsored Lens on Sunday.
There aren't many people who will believe that a prosthetic zipper face or gunshot wound to the eye (disgusting as they are) are real, but greyscale from Game of Thrones? That'll really unsettle people for awhile because it totally looks like an actual, honest-to-God infection that someone in 2017 could conceivably have. Which makes it very effective come Halloween, whether it's for a full-on Princess Shireen, Jorah Mormont, or Stone Man costume, or to just infect a completely different chara...
The first wave of iPhone X preorders, the ones with a delivery date of Nov. 3, sold out in ten minutes. You can still preorder one and skip the lines next week at Apple Stores across the country, but if you want that bezel-less beauty in your hands ASAP, brick and mortar might be the way to go.
You can pinch yourself, but you're not dreaming. Sprint is actually offering a year of (mostly) free, unlimited service for anyone who switches to the carrier. The only stipulation is that you must bring your phone with you, and it has to be one of the 27 eligible devices.
New York City may not be the friendliest city, but with the apps Via and Curb now letting users ride-share in the city's yellow taxis, New Yorkers can expect to snuggle up close in the back of a cab next to complete strangers. That's right, get ready to feel the love.
Usually, the mucus lining of the female genital tract presents a barrier that helps prevent infections. But, somehow, the bacteria that causes gonorrhea gets around and through that barrier to invade the female genital tract.
As most of you know, I am a strong advocate for using Linux for hacking. In fact, I would go so far as to say that you cannot be a hacker without knowing Linux well. I laid out various reasons for this in my "Why Every Hacker Should Know & Use Linux" article, and I even have a lengthy, continuing series on Linux Basics to help those new to Linux master it.
Hello friends!

In many programs on Linux, you'll come across programs which allow you to specify additional arguments instead of just simply running the program by itself. If you've used the Kali distribution, I'm more than certain you'll have come across these with the command line tools, else if you have been following these tutorials, we have already come across three tools which also use the same technique, i.e. gcc, gdb and wc. How do we do this with C? Let's find out.

The video for Robin Thicke's "Blurred Lines" got its fair share of attention due to the three topless models who star in it. In the second version, they're covered up, but just barely. Both the song lyrics and the lack of clothing sparked plenty of debate, controversy and even parodies.
"Ahoy-hoy." If telephone titan Alexander Graham Bell had his way, we'd all be answering phones like Mr. Burns. Thankfully, frienemy Thomas Edison had enough sense to realize we weren't always on the briny. He preferred "hello" as our standard telephone greeting, which he is credited with coining in 1877. Fellow American pioneer Davy Crockett actually used it as a greeting first in 1833 (as compared to an exclamation)—but in print, not over the phone.
If you're like me, the words 'monostable circuit' mean nothing to you. Until just recently, I had no idea what a monostable circuit did, or why anyone would ever need to use one.
If you're a certified computer nerd along the lines of NASA scientist Howard from "The Big Bang Theory," then you know how frustrating it can be transferring large amounts of data between an external hard drive or other drive and your main computer, especially when you're in a rush to get experiment data in.
