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.
Welcome back, my tenderfoot hackers! This is the third installment of my series on basic Linux skills that every hacker should know. Although some hacking tools are available for Windows and Mac, every real hacker uses Linux—for good reason.
Steampunking Nerf guns by painting them is a pretty common practice among Steampunks, but unfortunately, the really amazing-looking ones involve literally taking the gun apart, painting it, and then screwing it all back together.
Here's how to make dry-ice at home, or wherever you feel like it! All you need is a pillow case, and a CO2 fire extinguisher.
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.
The vast majority of people involved in Steampunk are interested in history but, like with science, there's something about history that we don't talk about very often: The holes.
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...
Steampunk is a tremendously interesting phenomenon because of its reliance on science fiction, and fiction in general. Steampunk can arguably be broken down into two categories: the fiction, and the aesthetic. Sometimes these categories cross over, but they're often more distinct than most people suspect; that said, the aesthetic is firmly based in works of fiction.
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...
No, Jack Dorsey's Cash app isn't about to launch an augmented reality device (er, I don't think...), but its latest outing is about as close as we've come to full confirmation that the wearable AR age is upon us.
The recent announcement that Facebook will begin inserting advertisements into its VR experience on its Oculus Quest headset has set the VR and augmented reality industry into a frenzy.
The experience of actually using the HoloLens 2 can be difficult to describe to anyone who hasn't had a chance to directly interact with the device in person and be blown away by its immersive capabilities.
The development of virtual reality at Facebook has been evolving lightspeed in the last few years. But while a relatively small group of VR enthusiasts and gamers are enjoying the social media giant's dedication to immersive headsets, it is the augmented reality space and its potential scale that truly has the tech market enthralled.
Based on recent reports, we've got a pretty clear picture of what to expect from Apple's rumored augmented reality headset expected to arrive next year, but the outlook is more opaque concerning its consumer-grade AR smartglasses.
For a hacker, there are a lot of advantages to creating a fake network. One advantage forces nearby devices to use their real MAC address if you happen upon a network that's stored in their preferred network list.
Your smartphone is likely full of COVID-19 news and coronavirus panic. These are scary days, and there doesn't seem to be any end in sight. If you're having trouble coping with the stress and anxiety the virus brings with it, know that your iPhone or Android device can actually help you, rather than just bring you further down.
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.
The worlds of augmented reality and virtual reality are closely linked in many ways. That means it's smart for AR insiders to keep a close on new developments in VR. If you have been paying attention, you know that Oculus CTO John Carmack is one one of the most important thinkers in the VR space.
Whenever the name Magic Leap comes up, the talk inevitably seems to turn to the company's big-name backers and "unicorn-level" amounts of cash poured into the venture. And if it's not that, observers tend to focus on the company's market strategy and overall prospects.
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.
Whenever a new, category-defining Apple product is in the works, we usually get a series of creative concept designs to accompany the rumors swirling around the prospective launch.
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.
The rise and fall of Meta, the Silicon Valley-based augmented reality startup that looked to challenge the likes of Microsoft's HoloLens, and others, took just six years.
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.
Over the last few years, the only thing teased by Magic Leap more than the Magic Leap One itself has been the company's flagship gaming title Dr. Grordbort's Invaders. The game, developed by New Zealand studio Weta Workshop, finally got its debut last week during the L.E.A.P. conference in Los Angeles.
While many of you were off surfing and lounging on some sandy beach or trying to figure out how to balance work with sky-high summer temperatures, I've been talking to all the companies that make augmented reality what it is today.
We've shown you the best augmented reality headsets, and now it's time to show you the rest. These are the AR headsets you've probably never heard of or even seen. The AR headsets that, in some cases, have a shot at the big time, and may one day reach widespread adoption, and, in other cases, are unwieldily contraptions that look like something out of a weird science fiction movie.
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.
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.
Trivia games are among the most entertaining ways to learn factoids and interesting info you may have never known about before. They're also the perfect genre to enjoy with friends and family, as they're particularly great at breaking the ice to make for a more memorable time together.
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.
As augmented reality becomes more and more integrated into the mainstream, people have been wondering the future of AR is going to look like. Jay Samit has a pretty clear idea.
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.
It looks like Chris Urmson has spent the six months since he left Google's Self Driving Car Project trying to build a get-rich-quick self-driving unicorn, along with Sterling Anderson, formerly with Tesla Motors. At least that is one of several scandalous accusations in a Tesla lawsuit aimed at the pair, and their secretive startup Aurora Innovation, LLC.
It's odd to see grown humans attempting to bounce off walls doing parkour. It's another thing altogether to see a robot doing it.
Few summertime drinks are as sweet, tart, and refreshing as lemonade. It can cool off even the hottest day and help you relax poolside, on the beach, or just sitting around the house.
Knowing if your meat is cooked properly is both the difference between a delicious meal and an inedible one... and the difference between making your guests sick and keeping them safe.
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.
Most of us lead busy, work-filled lives, often clocking in a 9-to-5 five days a week. And when that clock signifies the hour to leave, the last thing on anyone's mind is: "Time to go to the grocery store to pick up more fresh produce!" (Well, to be fair... maybe more people are psyched about this, but I know with certainty that I am not one of them.)
The start of a new year is generally thought of as a chance to start over, a time to improve or "fix" things in your life. Yet most people who set stringent New Year's resolutions find themselves failing within weeks—or even days—of setting their lofty goals.
