Any internet user will need to download files eventually, and most simply have faith that what they are downloading is trustworthy. This doesn't give much clarity into the contents of the file, but if the file's author published the original checksum, comparing it to the SHA-256 hash of the downloaded file can ensure nothing was tampered with.
So after setting everything up, creating the system, working with focus and gaze, creating our bounding box and UI elements, unlocking the menu movement, as well as jumping through hoops refactoring a few parts of the system itself, we have finally made it to the point in our series on dynamic user interfaces for HoloLens where we get some real interaction.
Steganography is the art of hiding information in plain sight, and in this tutorial, I'll show you how to use Steghide — a very simple command line tool to do just that. In addition, I'll go over a bit of conceptual background to help you understand what's going on behind the scenes. This is a tool that's simple, configurable, and only takes a few seconds to hide information in many file types.
This is a very exciting time for mixed reality developers and fans alike. In 2017, we have seen a constant stream of new hardware and software releases hitting the virtual shelves. And while most of them have been in the form of developer kits, they bring with them hope and the potential promise of amazing things in the future.
Every other year, Apple comes out with "S" model iPhones that enhance and speed up their main series models from the previous year. This year, however, because of the highly-anticipated 10th anniversary iPhone, aka the iPhone X, Apple has dropped the "S" and moved straight to the iPhone 8 and 8 Plus.
If you have a taste for sweets, you have at least one thing in common with mosquitoes. While too much sugar is unhealthy for humans, a new product makes sweets deadly to mosquitoes.
OpenVAS is a powerful vulnerability assessment tool. Forked from Nessus after Nessus became a proprietary product, OpenVAS stepped in to fill the niche. OpenVAS really shines for information gathering in large networks where manual scanning to establish a foothold can be time-consuming. OpenVAS is also helpful for administrators who need to identify potential security issues on a network.
DownToDash, an app from an NYC-based startup, connects students to other students who want to hang out the same way they do. The social networking app has gained increasing popularity since its launch in October 2016 and looks ready to become even more available. The app was founded by Sama Jashnani and Anuja Shah, both recent students themselves.
Crazy Taxi continues to be a favorite among gamers of all ages, from those who played the game in late-'90s arcades to those who discovered the game later on consoles. This weekend, Sega announced their mobile version of Crazy Taxi would now be available for free. What a time to be alive. So does the arcade classic still hold up in 2017? Let's find out.
After poor sales of last year's HTC 10 and the terrible reviews their first 2017 flagship received, HTC really needs the HTC U11 to succeed. But they're not taking things lying down, as they've come up with some interesting tech for their latest handset.
The big day has finally come—the new iPhone 7 and iPhone 7 Plus have been officially unveiled. Apple debuted their new flagship devices at a keynote event in San Francisco on September 7, and as we've grown to expect, there are tons of changes in store for the world's top-selling smartphone.
Throwaway phones aren't just for seedy criminals and spies—they can be useful for many everyday situations.
Smartphones have become such a big part of our lives these days that they're now closely associated with our personal identities. No longer is it Ford versus Chevy, rock versus rap, or PC versus Mac—now, you're either an Android person or an iOS person.
We spend over 30 percent of our lifetimes sleeping—yet it never seems like enough, does it? Distractions ranging from work issues to personal relationships keep our minds racing well after they should be shutting down for the night, and the onset of smartphones has only added to this problem with the instant information and easy entertainment that they offer.
Your brain holds a lot of precious information and is capable of great feats. However, there's one quality that doesn't lie among its strengths—memory security. Yes, that's right, your brain can be hacked, and it doesn't take a psychologist to do it. Anyone with the right know-how can change your memories for their own personal benefit, and you can do so to others, too.
As our lives grow busier, we get secluded in our indoor activities, consuming all types of fatty junk food and what not. Obesity is a very obvious yet unfortunate outcome of our unhealthy living standards. With it comes the predictable rush towards efforts to lose weight. Consequently, we have designed hundreds if not thousands of ways to lose fat and grow slimmer. To ease out your choice of ways, here is a list of the best ways to lose stomach fat. Step 1: Don't Eat Sugar
Welcome back, my tenderfoot hackers! As you know, Metasploit is an exploitation framework that every hacker should be knowledgeable of and skilled at. It is one of my favorite hacking tools available.
Unless you're someone who's terrified of social situations, chances are you love to talk. But no matter how much you want to share you life story or take over the conversation, you shouldn't. Your socially awkward coworkers that keep their mouth shut might actually have a leg up on you at work, and here's why.
Fifty-four percent of Americans 18 and older drink coffee every day, and why not? With 100 milligrams of caffeine per six ounces of drip coffee, it's just the morning beverage to wake you up and kickstart your day. You can feel the caffeine surge through your body like the Holy Ghost, making you aware, focused, and ready for action.
It may seem impossible to win an argument against an irrational person, but it turns out the tried-and-true techniques that hostage negotiators use against hostage-takers work surprisingly well in everyday situations. You may not ever deal with a real hostage situation personally, but life is full of negotiations with unreasonable people, and those conversations don't always have to end in rage or disappointment. The mental techniques that professional hostage negotiators use can help both pa...
Welcome back, my fledgling hackers! As nearly everyone has heard, Target Corporation, one of the largest retailers in the U.S. and Canada, was hacked late last year and potentially 100 million credit cards have been compromised. Happening just before Christmas, it severely dampened Target's Christmas sales, reputation, and stock price (the company's value has fallen by $5B).
The most recent premium flagship smartphones from Google — the Pixel 7 Pro and Pixel 6 Pro — are equipped with displays cable of 1440 QHD+ resolution. But they also come with a tool to downgrade to 1080p FHD+, which you may want to do in certain situations.
There are a surprising number of hidden features in your iPhone's Phone app, from secret dialer codes that provide info or perform actions to special characters that dial extensions automatically. However, there's one little-known trick every iPhone owner should know when using the Phone app for calls — and it's the simplest and most useful of them all.
A little-known setting on your iPhone gives you the power to change the color of certain contact names and email addresses when drafting an email. Customizing the color works well for visually separating contacts at a glance, and it can even help you from sending an email to the wrong person.
Since launching Google Lens as a a Pixel-exclusive feature in 2017, Google has not only expanded the availability of the tool to Android and iOS, but also built upon its functionality. Now, in addition to translator, tip calculator, personal shopper, and tour guide, Google has added math tutor to the job description for Google Lens.
The average iPhone user has between 60 to 90 applications installed. On one of my devices, I have over 600. With a ton of apps to sort through, it can sometimes be challenging to find the one you're looking for without having to use the Search tool (which is even better in iOS 14). Even then, you may still come up dry.
PirateBox is a great way to communicate with others nearby when cellular and Wi-Fi networks aren't available. With it, you can anonymously share any kind of media or document and even talk to one another by voice — without being online. However, it needs a Raspberry Pi, which is more expensive than ESP32 boards, and if you only need a text-based chat, there's a much simpler option.
When you don't have a steady cellular signal or immediate Wi-Fi access but need to communicate with others around you, you can set up an off-the-grid voice communications network using a Raspberry Pi and an Android app.
The camera on models in the iPhone 11 series includes an ultra-wide lens to take wider images, Night mode for taking better-looking photos in low-light environments, and a 16:9 frame for shooting. With these new features comes a slightly redesigned interface in the Camera app, one that even the second-generation iPhone SE received despite only having one of those three features.
With protests springing up across America, there's a chance you may have your first interaction with law enforcement. Many demonstrators will have their phones in-hand to film the action, which, sadly, could prompt an officer to demand the device and any self-incriminating data it may contain. Before this happens, you should know there are tools at your disposal to protect your data in such situations.
In many urban areas, GPS doesn't work well. Buildings reflect GPS signals on themselves to create a confusing mess for phones to sort out. As a result, most modern devices determine their location using a blend of techniques, including nearby Wi-Fi networks. By using SkyLift to create fake networks known to be in other areas, we can manipulate where a device thinks it is with an ESP8266 microcontroller.
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.
When Facebook launched its first hardware products last year, the Portal and Portal+ smart displays, the company mostly touted its video-calling features as it faced off against Amazon and its Echo Show.
While iOS 13 introduces over 200 new features for your iPhone, one of the biggest focuses this year is Photos and Camera. The update completely overhauls the Photos app, creating a more organized and natural way to interact with your pictures and videos. You'll also find a few new tricks in the Camera app. In all, Apple has added over 30 new features to your shooting, editing, and viewing experience.
While modern browsers are robust and provide a lot of functionality, they can be unlocked to do some pretty spectacular things with browser extensions. For hackers and OSINT researchers, these tools can be used to defeat online tracking, log in to SSH devices, and search the internet for clues during an investigation. These are a list of my top ten favorite browser extensions for hackers — and how to use them.
A rainbow table can be thought of like a dictionary, except instead of words and their definitions, it holds combinations of characters on one side and their hashed form on the other. What is a hash and why would you want to know what random combinations of characters are hashed into?
We recently set out to find the best phones for people whose primary usage revolves around social media apps like Facebook and Instagram. Samsung, Apple, and Google were the three brands that made our top five, and while the latter only had one finalist, the two bigger OEMs had a pair of phones each. What struck us, however, was that Samsung's phones edged out Apple's not once, but twice.
No matter how good a display is, the idea of perfect color calibration is subjective — some prefer warmer more saturated colors, while others prefer the calmer cooler side of the color spectrum. It is almost impossible to create a single color calibration that everyone can agree on out of the box. The display on the Pixel 2 XL was specifically calibrated with a more realistic color profile in mind.
After getting confirmation from Tim Sweeney, CEO of Epic Games, we now know Fortnite Battle Royale will not be available on the Play Store when it's finally released for Android. Instead, users will have to download the APK directly from Epic Games' website — and quite frankly, this is a bad idea.
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.
