How To: Introduction to Modern Cryptography

Cryptography is the science of keeping secrets, or more specifically, the science of disguising them. As a point of fact, cryptography has progressed quite a bit farther and now encompasses file and message integrity, sender authentication, and pseudo-random number generators.

How To: 9 DIY Tricks for Cleaning Your Car

Ever see those cars so covered in dirt, dust, and grime that someone writes "Wash me" on it using their finger? Well, for those cars' sakes, as well as cases less extreme, a word of advice: procrastination is not a solution — it can only compound the problem. Self-cleaning cars are the stuff of the future, not the present, and your car needs attention now.

News: Why Defining Steampunk Is Worthwhile

I've tried my hand in the past at defining Steampunk, but as anyone else who has made a similar attempt will tell you, there's a significant backlash from the community against working to create a real definition of what Steampunk is. That may sound ridiculous to some, but it's a very serious matter to others. With the recent announcement that TeslaCon 4 will be called the Congress of Steam, I think it's appropriate to talk about why all of this stuff is worth it. In this article, I'm going t...

How To: Create a Steampunk Persona

Before I really get into this article, it's important to note that you do not need a Steampunk persona (or "steamsona") in order to be a Steampunk, or wear Steampunk clothes. Some people like to pretend to be a different person when dressed up in Steampunk clothing, but that is entirely optional, and only to be done if it appeals to you. That said, even if you aren't actually acting as your character, it may still be helpful to have one in mind when putting together an outfit. Personally, I'v...

How To: Get Started with MicroPython for ESP8266 Microcontrollers

For anyone interested in using cheap, Wi-Fi-connected microcontrollers like the ESP8266, the Arduino programming language can be a barrier to entry. Based on C++, Arduino requires knowledge of more computer science than languages like Python. Fortunately for beginners, setting up MicroPython on an ESP8266 allows anyone to write Python on affordable microcontrollers in a matter of minutes.

News: GarageBand Changed How My Autistic Son Interacts with the World

My autistic son loves music. One afternoon, when he was nine, I downloaded GarageBand to his iPhone to help with the boredom of a long wait at a doctor's office. Instead of pacing or escalating into a meltdown, he spent the entire hour and a half practicing, learning, and composing. When we finally left that day, the rest of us exhausted and irritated, he shared his first composition with a big smile.

How To: Spy on Network Relationships with Airgraph-Ng

What if you could easily visualize which access point every Wi-Fi device nearby is connected to in a matter of seconds? While programs like Airodump-ng can intercept this wireless information, making it easy for hackers to use and understand is another challenge. Fortunately, a tool called Airgraph-ng can visualize the relationships between Wi-Fi devices from only a few seconds of wireless observation.

Hands-On: Hands-On with Spatial's Remote Meeting App on Microsoft HoloLens

In recent years, many software publishers have tried to sell the business community on remote meetings via VR, but if social media chatter is any indication, it hasn't taken off in a big way just yet. However, for some, the notion of holding remote meetings using augmented reality, a medium in which you're still directly tied to the real world and not closed off in a blindfold-style VR headset, might be the better solution.

How To: It's Not Just Your Camera & Mic — Here's All the Crazy Ways Your Phone Could Be Used to Spy on You

As you're surely aware, your phone can be used against you. Thanks to our cameras and microphones, a clever hacker can obtain access to your device and invade your privacy. But spying isn't limited to just these two sensors — gyroscopes, proximity sensors, QR codes, and even ads can be used to paint a very clear picture about who you are and what you're currently doing.

News: Intel Labs Chief Reveals the Secrets to Taking Augmented Reality Mainstream

Because augmented reality is still so new to so many people, there are a number of would-be experts opining online, often repeating basic facts anyone with a spare 15 minutes can find on their own. That's why it's important to point out when someone delivers what could be considered the ultimate cheat sheet for ramping up your AR IQ if you're unfamiliar with the finer points of the space.

How To: Generate Private Encryption Keys with the Diffie-Hellman Key Exchange

When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.

How To: Scrape Target Email Addresses with TheHarvester

Open-source data scraping is an essential reconnaissance tool for government agencies and hackers alike, with big data turning our digital fingerprints into giant neon signs. The problem is no longer whether the right data exists, it's filtering it down to the exact answer you want. TheHarvester is a Python email scraper which does just that by searching open-source data for target email addresses.

How To: 10 Must-Have Chrome Tools for Lazy Students

Chrome apps and extensions are powerful tools for students: they can help optimize your web browsing experience by helping you take notes, check your grammar as you compose documents and emails, and even help you squeeze a little more juice out of your laptop's battery by freezing unused tabs and optimizing YouTube streams.
