Welcome to the final tutorial of the series on standard C. This article will cover the linked list abstract data type (ADT). There will be a lot of abstraction to try to deliver the understanding in the most basic way for easiest interpretation of what they are and how they work, then we will get into the guts of it and learn the technical code underneath. For those who have yet to grasp the concept of pointers, it's advisable that you do that first before approaching this. Having learned thi...
If you haven't read the last article, feel free to stop by and give it a read, but abstaining from reading it will not, for the most part, be detrimental to your understanding.
We are most certainly not machines. We all need some downtime every once in a while to set our sanity scales back in balance, which in turn, makes us more productive workers. This is a premise that several forward-thinking employers fully understand, but these types of companies are few and far between in corporate America.
Unruly customers. Crazy exes. Horrible bosses. When you need proof of insanity or just want it for your records, recording a phone call is a must. Problem is, it's not the easiest thing to do on an iPhone — but it's completely possible.
One of Android's biggest strengths, when compared to other mobile operating systems is its open file structure. Google introduced a built-in file manager with Marshmallow that provides basic file management, but like with most apps on Android, there are alternatives. Third-party file managers are readily available, providing deeper access and control of all your files.
Each day, we read about another security breach somewhere in our digital world. It has become so commonplace that we hardly react anymore. Target, J.P. Morgan, iCloud, Home Depot, and the list goes on and on.
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.
One aspect of Android's interface that remains clunky is its gesture- or button-based navigation bar, mainly because app developers aren't fully utilizing the tools available to them. But a new feature Google is working on may finally make your nav bar more uniform across your apps.
If you hate matching images, typing letters and numbers, solving math problems, and sliding puzzle pieces for CAPTCHA human verification, you'll love Apple's newest privacy feature for apps and websites.
While you can quickly see the edit history of a modified iMessage in the Messages app, there's no way to view an iMessage that somebody in the conversation deleted unless you happened to see it before it disappeared. But that's only true if you didn't implement these security measures on your iPhone.
The tactic of brute-forcing a login, i.e., trying many passwords very quickly until the correct one is discovered, can be easy for services like SSH or Telnet. For something like a website login page, we must identify different elements of the page first. Thanks to a Python tool for brute-forcing websites called Hatch, this process has been simplified to the point that even a beginner can try it.
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.
OnePlus will be releasing a new phone in the second half of 2018, specifically, an upgrade to their T-series. Over the past two years, #T versions have come out about five months after their predecessors and have included small updates that fix any problems from the previous OnePlus device. While we do know a bit about OnePlus 6T, what it could be is much more exciting.
Look, tests are no fun, and doing poorly on them is rarely an option. Whether you're studious or a slacker, everyone needs a little boost now and again. While students have found ways to cheat as long as tests have existed, the invention of smartphones has greatly enhanced the potential to get ... creative.
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.
If you're using a mobile device, it's a pretty safe bet that your apps are sending lots of information back and forth from their servers. To make sure there is no inappropriate data collection going on, it's worth setting up a web proxy to spy on this traffic, so you know exactly which apps are "phoning home" and when.
When you can't reach your iPhone or don't have it on you, how do you get help from emergency services? Unless you have one of those life-alert mobile triggers, someone nearby, or some amazing telepathy skills, hope might be the only answer — unless you wear an Apple Watch, that is.
Its official: On May 8, T-Mobile finally released the Android Oreo update for the LG V30 and V30+. Now, every major US wireless carrier has pushed the update. For me, this update is a big deal. Not only does Android Oreo bring some new tools and features, but LG has also included a few additions as well.
One feature in iOS you're likely underutilizing is 3D Touch, a highly useful, unique tool for iPhones ever since it first appeared on the iPhone 6S. Apple's pressure-sensitive interactivity gives iOS an extra layer of functionality, which can be clearly seen across the entirety of your device. From the lock screen to the home screen to the apps in between, there are plenty of ways to use 3D Touch.
Design flaws in many routers can allow hackers to steal Wi-Fi credentials, even if WPA or WPA2 encryption is used with a strong password. While this tactic used to take up to 8 hours, the newer WPS Pixie-Dust attack can crack networks in seconds. To do this, a modern wireless attack framework called Airgeddon is used to find vulnerable networks, and then Bully is used to crack them.
It's easy to have your password stolen. Important people like executives, government workers, journalists, and activists face sophisticated phishing attacks to compromise their online accounts, often targeting Google account credentials. To reduce this risk, Google created the Advanced Protection Program, which uses U2F security keys to control account access and make stolen passwords worthless.
Coinhive, a JavaScript cryptocurrency miner, was reportedly discovered on the BlackBerry Mobile website. It was placed there by hackers who exploited a vulnerability in the site's e-commerce software that allowed them to anonymously mine cryptocurrency every time the website was viewed. There's no doubt Coinhive, an innovative mining method, is being abused and exploited by hackers in the wild.
The holidays are stressful. Between traveling, family, and dinner, Thanksgiving weekend can feel like weeks. Many families have traditions that make the days long, but some of us would rather curl up somewhere and watch our favorite shows. But all is not lost — our phones do so much for us now that they can help make the long stressful weekend much more bearable.
Armis Labs has revealed eight vulnerabilities, called "BlueBorne", which put 5.3 billion Android, iOS, Windows, and Linux devices that use Bluetooth at risk. With it, hackers can control devices, access data, and spread malware to other vulnerable devices through networks. In this post, we will learn about the vulnerabilities, then look at how to find devices that have them.
What happens when a entrepeneur/theme park creator and special effects artist/magician team up? You get a team crazy enough to create the first true virtual reality theme park (sorry, Six Flags). They only have a single experience so far, but it's already taken a giant leap beyond the wonders we've seen in today's consumer virtual reality headsets.
Greetings all. Today I intend to append a new series to my mini-collection of posts. This series will consist of informative guides for the purpose of depicting certain aspects of the White Hat profession that I believe are of profound importance. Furthermore, I will keep this series simple for everyone to follow, regardless of your tech level. So without further ado, let's get right into it.
Hello and welcome to my article. I have made this article for anyone who wants to become a hacker, and wants to know how to get started.
As I said in this earlier post, there's no easy way to explain or define the Steampunk aesthetic. There are a large number of Steampunk tropes or "cues", as I call them, that bring to mind the feeling of Steampunk. These cues combine to push past the "not-Steampunk" threshold into firmly "Steampunk" territory.
Apple's spring event, where the company will announce a new iPad model, is just around the corner. We also expect to see the long-awaited Apple Pencil (3rd generation), also known more simply as Apple Pencil 3, with several significant enhancements that promise to make it an indispensable tool for anyone who uses their iPad for note-taking, sketching, illustrating graphics, and more.
Some websites require you to perform a verification task so they know you're human and not a bot. It helps websites curb spam, abuse, unauthorized access, and cyberattacks but also adds an obstacle for anyone trying to visit their content. If you find it more of a nuisance than a necessary evil, there's an easy way to reduce the number of human verification prompts you receive on your iPhone, iPad, and/or Mac.
Safari isn't the only web browser on your iPhone or iPad that will let you add icons to your Home Screen for progressive web apps and website bookmarks. Apple gave developers the key to its "Add to Home Screen" feature, and your favorite iOS or iPadOS web browser may already support it.
You may not realize it, but most of your apps include third-party tracking services that monitor your activity in other apps and websites to serve highly-targeted ads to you. But now you can stop the creepy behavior on an iPhone and Android phone.
Apple wants to support the advertising economy, but its primary focus of late has been user privacy and security. In Safari, cross-site tracking, which lets content providers track you across websites and apps to show you more targeted ads, is disabled by default. However, content providers can get around that using less privacy-invasive ad measurements, but you can stop that too in iOS 14.5.
Google's been on a mission to improve the privacy and security of Android lately, and Samsung's always been at the forefront in these areas. As a result, One UI 3.0, which is based on Android 11, is the most secure OS version to ever hit Galaxy phones thanks to few key changes and new features.
The $35 Raspberry Pi is an amazingly useful single-board computer (SBC) with a good balance of price, performance, and connectivity options. But for some projects, it just isn't enough. Whether you need more computing power, a smaller size, or better machine-learning capabilities, there are other options available.
Smartphones and laptops are constantly sending Wi-Fi radio signals, and many of these signals can be used to track us. In this guide, we'll program a cheap IoT device in Arduino to create hundreds of fake networks with common names; This will cause nearby devices to reveal their real trackable MAC address, and it can even let an attacker take over the phone's data connection with no warning.
I was in college, and my 15-inch Sony Vaio laptop was my prized possession. It was my first PC and probably the most important thing I brought with me to my dorm — it was both how I completed my assignments and my primary source of entertainment. How could it turn its back on me in my time of need?
Smartphones are still "phones," which means communicating with others is usually a primary use. Ranging from a simple "hi" to a more personal conversation and even sharing passwords, our messages should remain private so that only the intended recipient sees their content. While many apps tout end-to-end encryption, not all apps prioritize security and privacy.
The most significant customization aspect of the iPhone is most definitely the home screen. Before iOS 14, Apple only threw in a feature here and there to appease those who like a more personal touch on the most visible part of the operating system. Now, there are great customizability options to give you a real personalized touch, and that includes app icons.
