How To: Understanding Signature Schemes: How Data Sources Are Authenticated, Secured, & Spoofed

One of the biggest problems in data security is authentication of data and its source. How can Alice be certain that the executable in her inbox is from the venerable Bob, and not from the not-so-venerable Oscar? Clearly Alice wants to know because if this file is actually sent to her by Oscar, the file might not be a game, but a trojan that can do anything on her computer such as sift through her email and passwords, upload her honeymoon pictures, or even turn on microphones and webcams. Thi...

How To: Make Your Favorite Song Last Forever with Infinite Jukebox

The first album I ever bought with my own money was Nirvana's MTV Unplugged in New York. It featured mainly lesser-known songs and covers, but was on constant repeat on my Walkman. While the whole album was fantastic, there was one song that stood out the most to me—"The Man Who Sold The World." The song (originally written by David Bowie) kept me under a spell, which had me replaying the song over and over and over and over. As I got older, I found myself sharing this relationship with a han...

How To: Hack WPA WiFi Passwords by Cracking the WPS PIN

A flaw in WPS, or WiFi Protected Setup, known about for over a year by TNS, was finally exploited with proof of concept code. Both TNS, the discoverers of the exploit and Stefan at .braindump have created their respective "reaver" and "wpscrack" programs to exploit the WPS vulnerability. From this exploit, the WPA password can be recovered almost instantly in plain-text once the attack on the access point WPS is initiated, which normally takes 2-10 hours (depending on which program you use).

Dev Report: Machine Learning Agents Come to Unity

As we have seen previously with the likes of SethBling's Mar I/O videos and other examples, video games seem to be a great source for training AI neural networks. Augmented reality and machine learning are part of a collection of technologies that seem to be growing toward a point of maturity, and that will likely cause them to be intertwined for the foreseeable future. As developers, machine learning will definitely change the way we create software in the coming future. Instead of going lin...

How To: Use YouTube's Search Filters to Find Videos Faster

Have you tried searching for 4K HDR videos on YouTube, only to get 1080p videos just because the uploader used "4k" or "HDR" in the description? Or have you tried looking for a video about something that just happened, except YouTube's algorithm surfaces established videos first by default, so all the results you get are older than a month? Well, there's a better way.

How To: Turn Your Favorite Pics into Photo Mosaics on Your Nexus 7

Photo mosaics have interested me since I was a kid. I could never understand how someone took the time and effort to make one large masterpiece out of hundreds of smaller images. Maybe I'm too daft to grasp the concept, but it seems extremely difficult. I certainly don't have the necessary skills to make my own work of art, but luckily my Nexus 7 does.
