I love cryptography. It is like a great gigantic puzzle for me to solve. However, it is more important than that. It is also how we keep secrets safe. Not just sorta safe either, but really safe.
Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.
Cut cardboard into 8" long x 3" wide strips. With cardboard down on a cutting board, place 1 AA battery on one end.
In the battle for best stock Android flagships, there are really only two choices: Google Pixel phones and OnePlus phones. Although the latter isn't true stock Android, it is impressively close and usually paired with more impressive hardware than the Pixel lineup. The latest is the OnePlus 6T, which will be a bit controversial for fans this year.
Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to sniff the air for packets from any device we want to track, turning on an LED when it's detected nearby.
This time last year, we got our first taste of what mobile app developers could do in augmented reality with Apple's ARKit. Most people had never heard of Animojis. Google's AR platform was still Tango. Snapchat introduced its World Lens AR experiences. Most mobile AR experiences existing in the wild were marker-based offerings from the likes of Blippar and Zappar or generic Pokémon GO knock-offs.

There's an official way to install apps onto your Android phone using basically any device that has internet access — heck, you can even download new apps from an iPhone and they'll install in seconds on your Android device.
Apple's big iOS 14 update includes Memoji improvements such as new hairstyles and headwear to choose from for your personalized Animoji character. Even better, there are now face coverings, so you no longer have to resort to that one masked emoji to get the point across in these times of COVID-19.
A modern iPhone is capable of running sophisticated, exquisitely-rendered games that rival titles on current-generation consoles. However, there is some value in classic video game titles, whether you grew up playing games on the Atari 2600, Nintendo Entertainment System, and Sega Genesis or not.
The COVID-19 pandemic has practically shut down all sports except for World Wrestling Entertainment, which has continued staging matches without an audience, leaving us sports fans with nothing much to cheer for. While they can't replace live games, smartphone games provide an alternate reality to live out our competitive entertainment in the absence of the real thing.
It feels strange to be walking through an open field in a small village in the English countryside. There's no one else around — just the four of us: me, my husband, my 12-year-old son, and my adult niece. The day is spectacular, particularly for England. The sun is shining, and the temperature is in the low '70s.
Directory traversal, or path traversal, is an HTTP attack which allows attackers to access restricted directories by using the ../ characters to backtrack into files or directories outside the root folder. If a web app is vulnerable to this, an attacker can potentially access restricted files that contain info about all registered users on the system, their permissions, and encrypted passwords.
The gym can be pretty distracting. With the slamming of weights and pieces of equipment, loud music blasting through the speakers, and plain old grunting, it can be challenging to focus on your workout. However, with your just your phone, you can not only eliminate these distractions but make the most of your time there.
Mystery is a tricky thing. Used correctly, it can give onlookers the impression that wondrous and perhaps valuable things are afoot. However, once the veil of suspension of disbelief is removed in any significant way, that same mystery can quickly turn into not just skepticism, but outright anger at what may have seemed like an attempt to dupe trusting onlookers.
One could argue that, at least for the moment, software development is more important to the augmented reality experience than hardware. Since a viable augmented reality headset has yet to emerge for the broader, mainstream consumer market, currently, the same devices that make texting and selfies possible are leading the charge to enable easy-to-use AR experiences.
Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.
Due to weaknesses in the way Wi-Fi works, it's extremely easy to disrupt most Wi-Fi networks using tools that forge deauthentication packets. The ease with which these common tools can jam networks is only matched by how simple they are to detect for anyone listening for them. We'll use Wireshark to discover a Wi-Fi attack in progress and determine which tool the attacker is using.
There's actually more to the dialer screen on your OnePlus than meets the eye. Besides its obvious purpose of calling people, there's a vast array of secret codes that you can input to troubleshoot your device, in addition to revealing important information, making anonymous phone calls, and so much more.
There has been significant debate over law enforcement's right to access our digital devices in recent years. New tools from Grayshift and Cellebrite are popping up faster than ever to help government agencies, as well as traditional hackers, break into iPhones. If you're concerned, you can take steps right now to beef up your passcode and prevent outsiders from gaining access to your device.
There's no doubt Kali has established itself as the most popular penetration distribution available. However, just because it's the fan favorite of beginners and security researchers doesn't make it right for everyone. Manjaro Linux is a beginner-friendly Arch-based distribution which can be easily weaponized with the Black Arch expansion, creating a friendlier first-time Arch experience.
The iPhone X was released in November 2017, and the iPhone 8 and 8 Plus dropped right before it, but the hottest news right now revolves around the 2018 iPhone releases. The rumor mill regarding the iPhone X's successor started churning out speculations on names, cameras, display size, and more almost immediately after last year's devices, and there have been many new leaked details since.
There are a lot of Android phones out there, and chances are that someone in your life is looking for one this holiday season. Well, there also happens to be a lot of Black Friday deals on Android phones this year. So we've rounded up the best deals taking place on Black Friday weekend to help you save big.
Clumsiness is the great equalizer when it comes to smartphones — it makes no distinction between the most expensive flagship handset and cheaper mid-range models. A hard drop onto pavement will usually result in a shattered screen, regardless of how pricey your device is. And with a smartphone breaking every two seconds, we're truly our own handset's ultimate nemesis.
Aircraft equipped with ADS-B are constantly shouting their location into the radio void, along with other useful unauthenticated and unencrypted data. In this guide, we will make an ADS-B receiver using a Raspberry Pi with a software-defined radio (SDR) dongle, which we can use to track aircraft anywhere in real time.
In our first part on software-defined radio and signals intelligence, we learned how to set up a radio listening station to find and decode hidden radio signals — just like the hackers who triggered the emergency siren system in Dallas, Texas, probably did. Now that we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting in a radio-connected world.
On April 7, 2017, residents in Dallas, Texas, woke to the sound of emergency sirens blaring all over the city. No one could shut them off, and after repeated efforts to contain the situation, the city had to shut down the entire system. While the media reported a sophisticated computer hack was responsible, the truth was much less high-tech.
Fight me all you want, but it ain't a party without alcohol—whether it's a Halloween party, Christmas party, dinner party, or even a damn wedding. (If you think that people will stick around after dinner for a dry wedding, then you're sorely mistaken.)
There is much to be learned about Apple Music and the revamped Music application introduced in iOS 8.4. Throwing their hat into an already competitive field with other companies like Spotify, Tidal, or Rdio, this is a bold move on Apple's part. So, before you consider signing up for the new streaming service, let's take you through all the changes and features you should know about before doing so.
Hello again, faithful readers. For today's lesson, we will be learning the correct way to restring and tune an electric guitar. I almost wasn't going to post this because it is so basic. But, as with many basic tasks, there are a lot of people who know how to do it, but can't really do it right. If you are a new guitarist, this is an essential piece of maintenance work, because guitar shops usually charge way too much for this task. Of course, I'm kinda cheap, so even 5 bucks is too much for ...
There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this part, I'm actually going to tell you more than just how to make a crystal radio, but I'm also going to explain how and why they work. Crystal radios are pretty Steampunk in and of themselves, since they were first developed in the late 19th centu...
I obviously do a lot of Steampunk projects, but there are a ton of things out there that I haven't tried yet. So, in an effort to broaden my horizons, I recently taught myself how to use Arduinos, which I plan to incorporate into some of my future Steampunk builds.
Thrift stores! As a Steampunk, they can be your best friend, but it's easy to make a tragic mistake. This hands-on guide will help you navigate the murky waters of successful thrifting in order to find the hidden gems that will make your Steampunk outfit complete!
One of the best things about Christopher Nolan's Batman trilogy is how realistic he makes the caped crusader feel. Unlike the Joel Schumacher or even the Tim Burton versions, Nolan's world seems grounded in some level of scientific fact. But just how close is science to actually being able to replicate some of the Dark Knight's gadgetry?
Google and Snap held their annual conferences this week, and both companies managed to upstage their new AR software features with fantastic new AR hardware.
On May 17, Apple announced that Lossless Audio playback for Apple Music was finally coming to subscribers in June. The long-awaited option will let users stream songs at a much higher quality than ever before. Still, in the fine print, Apple noted that you wouldn't be able to listen to the best sound quality — Hi-Resolution Lossless — on your iPhone without a DAC.
The Lens Studio creators have published more than 1.5 million AR effects to Snapchat. One of them is Audrey Spencer, who shared her story with us and provided her insights into Lens Studio as a storytelling device. Meanwhile, Snap has added new capabilities to the platform to stoke more creativity from its creators.
Whether you want to give a gift that your loved one has wanted all year or one that they never even knew existed, there's something awesome for everyone in these gifts. Just as exciting as their innovative features is their price.
Biometrics have a major flaw: they don't work well with personal protective equipment. Whether it's a mask obscuring facial recognition or gloves blocking the fingerprint scanner, it's a lot harder to unlock your phone when you're wearing the proper PPE. Thankfully, there are a few ways to speed things up.
Over the past decade, Marvel Studios has been a dominant force at the box office, raking in more than $21 billion dollars. Averaged out over that span of time, the yearly earnings of those movies outweigh the gross domestic product of some countries.
