Hello everyone! I hope you are having a great day so far. Today, instead of caring about networks we are going to talk about subnetting based on host requirements as promised in my first article about subnetting. Just like in the previous articles we will jump right into the examples because that's the best way to learn.
Hello everyone! How's subnetting going? Did you practice a lot? I hope you did, but even if you didn't we will go through some more examples so you can be feeling confident after reading this article. It's all about that bad boy binary!
One of the hottest trends in the food world right now is "spiralized" vegetables. I will confess that I am a bit suspicious of any diet or food fad that eliminates an entire food group for anything other than physician-ordered health reasons, but something really good has followed in the wake of the Atkins/paleo/gluten-free movements.
My daughter moved into her first apartment last year, a huge rite of passage in any young person's life. With a mother and two grandmothers who are good cooks (to say the least, in the case of the latter), it's not surprising that she turned to us for some advice about how to improve her own skills in the kitchen. Without question, the single best piece of advice we have given her is to employ mise en place each and every time she prepares a meal.
Sooner or later, you're going to come across a person at work that you don't like—or someone that doesn't like you. This can result in uncomfortable tension, insulting gossip, and a disrespectful attitude, to name just a few of the negatives. But it doesn't have to be that way. The next time you're having a workplace conflict with a particularly challenging coworker, the best thing you can do is keep your mouth shut, and here's how to do it.
While password cracking and WPS setup PIN attacks get a lot of attention, social engineering attacks are by far the fastest way of obtaining a Wi-Fi password. One of the most potent Wi-Fi social engineering attacks is Wifiphisher, a tool that blocks the internet until desperate users enter the Wi-Fi password to enable a fake router firmware update.
Mobile payment systems have been around for almost 5 years now, starting with Google Wallet. But when Apple got into the game last year with their new Apple Pay service, things really started to take off. Around this time, Samsung responded by acquiring an up-and-coming mobile payments company that owned the rights to an incredibly innovative technology called Magnetic Secure Transmission (MST).
Hi there, nullbytes :) I've recently seen many questions regarding VMs with Kali, and personally I prefer using a Live Boot USB to get Kali without removing my system (and for many reasons).
Welcome back, my future hackers! After my first tutorial about doxing, I decided I would dive a little bit deeper into the world of social engineering. In this tutorial we will learn some basic social engineering techniques to get into a company building, find out more information about the company's security, and maybe even exploit the company's computers if you get the chance.
Welcome back, my greenhorn hackers, and happy New Year! Now that your heads have recovered from your New Year's Eve regaling, I'd like to grab your attention for just a moment to preview 2015 here at Null Byte. I hope you will add your comments as to what you would like to see, and I'll try to honor as many requests as I can.
Heartbleed, move over. There's a new bug in town, and this time it's also affecting Mac and Linux computers. It's called Shellshock (its original official title is CVE-2014-6271), and it's currently got a 10 out of 10 severity rating over at the National Cyber Awareness System. While some updates have been issued to fix this bug, they were incomplete, and your system is probably still vulnerable, as it has been for the last probably 20 years.
Just the fact that you own an Android device means you're privy to an entire world of third-party development. Many of the mods you'll see here on Gadget Hacks can be performed fresh out of the box, but with root and Xposed, the list grows longer. But to truly be able to take advantage of all that Android's massive development community has to offer, you'll need to have a custom recovery installed.
Welcome back, my hacker apprentices! To enter the upper echelons of hackerdom, you MUST develop scripting skills. It's all great and well to use other hacker's tools, but to get and maintain the upper hand, you must develop your own unique tools, and you can only do that by developing your scripting skills.
The holiday season is almost over, bringing the year to an end, and what better way to end it than with some tonsil hockey from the dime across the room on New Year's Eve?
Welcome back, my novice hackers! My recent tutorials have been focused upon ways to NOT get caught. Some people call this anti-forensics—the ability to not leave evidence that can be tracked to you or your hack by the system administrator or law enforcement.
Despite the security concerns that have plagued Facebook for years, most people are sticking around and new members keep on joining. This has led Facebook to break records numbers with over 1.94 billion monthly active users, as of March 2017 — and around 1.28 billion daily active users.
TouchDevelop is a browser-based programming tool that allows anyone to build your own Windows 8 apps directly from any touchscreen device, including iPad, iPhone, Windows Phone, Android, PC and Macs. Once the script is created and the app proves to work, it can be placed in the Windows Store for free or purchase.
All kinds of people pretend to be someone they're not on the internet, including scammers, people attempting to wind others up, hackers and web predators. Almost all of these people will leave bases uncovered and they're all easy to expose when you understand how to. Here are my favorite ways of finding out when somebody is lying quickly. Image Search
Welcome to Minecraft World! Check out our tutorials, post to the Inspiration board, and come play on our free server! HELLO, FELLOW MINECRAFTERS. Pmaguire here, bringing you my favorite idea for a competition so far! I hope that you will come to love it as much as I do! Well, starting off, as the title states, this week's Redstone Competition will be PvP Arenas! Except, not just ones where you physically fight. You have to have traps, things that make it hard to fight, and various ideas using...
If you read my article on the OSI model, you got a good overview on communications from that model's perspective, but how does that relate to TCP/IP? We're going to take it a step further, getting into the idea behind the two address concept. How does an IP address and a MAC address work together? If you want to hijack sessions and all sorts of lulz like that, you need to understand these concepts. Let's get into it, mates!
All you science and astronomy nuts out there, pay attention, this detailed video tutorial series will tell you everything you need to know about using the Meade DS-2000 Series Telescope to ogle the universe.
If you were upset about "Friends" leaving Netflix, fret no more. The entire series, all eight Harry Potter movies, as well as HBO's massive catalog, are now available as part of HBO Max. If you're already an HBO Now subscriber, however, it can be a bit confusing to know how to switch over to this brand new service. Here's how.
Not every app is designed well. With nearly 3 million apps on the Play Store and countless more that you can sideload from other sources, there are bound to be a few stinkers. And many of them do a terrible job using RAM.
There are two main ways to view how much battery is remaining on an iPhone: the battery level icon and battery percentage. Out of the box, the second-generation iPhone SE only shows the battery level icon in its status bar, which only gives you a rough idea of how much juice is left. But there are ways to view the exact percentage instead.
The still-unfolding story of China's Nreal augmented reality startup continues to develop, with each turn uncovering another unexpected wrinkle.
The camera system on the iPhone has never been better. Apple's iPhone 11, 11 Pro, and 11 Pro Max sport some of the best shooters on the market. But no level of quality makes up for the fact that shady apps can access your cameras for nefarious reasons. You can take control of the situation, however, and block any app you want from using your rear and front-facing cameras.
Apple has their regular iPhone 11, then two higher-end "Pro" models. Samsung went the other way — they have the Galaxy S20 and S20+, then there's the S20 Ultra. But one thing these smartphone lines do have in common is the base model flagship. How do they compare?
The time to wait for an absolutely killer phone from Samsung is over. They've released a giant of a phone known as the S20 Ultra, and at least on paper, it's a grand slam. But only a few months ago, Apple released its first "Pro" iPhone, and it was giant in its own right. So which is better?
After three rounds of beta testing, Apple finally released iOS 13.3.1 today, Jan. 28. It's the latest update to iOS 13, coming exactly seven weeks after the release of iOS 13.3. So, what's new?
It happens to almost everyone. You wake up one morning, check your phone, and realize your alarm never went off. Now you're late to start the day, and you spend every night onward paranoid it'll happen again. But if you have an iPhone, there are two things you can check to make sure the alarm always goes off on schedule.
Did Google CEO Sundar Pichai kill Google Glass for non-enterprise users? That's the obvious first question following news that non-enterprise Glass users will no longer have access to Google's core apps after February 2020.
Have you ever walked around in public and heard the same handful of default ringtones over and over again? How do these people know who's calling without looking first? It's tough to tell when they all sound the same, but there is something crafty you can do to help with that. Using a different ringtone for certain contacts will allow you to differentiate between them instantly.
Best known for its mobile phones and television sets, South Korea's LG has had a quieter presence in the US compared to the country's homegrown efforts.
All those Apple commercials encouraging people to use their iPhones to make their smartphone movies look amazing, but how can you achieve some of the same looks? That's the question many often ask after plunking down over $1,000 for a brand new iPhone, shooting some video, and getting somewhat mediocre results.
A typical hours-long podcast can cover a broad range of topics, and it's not uncommon to stop listening halfway through an episode or to skip through the parts you don't want to hear. Unfortunately, in the Apple Podcasts app, unfinished episodes remain within the app's My Episodes list and will play again automatically once you've finished a previous episode.
A new profile on Apple's exiting design chief Jony Ive, the man behind many of the company's most successful products, paints a fuller picture of what led to his departure.
When there's a new game you want to play or app you need to use, but a Wi-Fi network isn't available, you can always download it over cellular data. If the size of the app is too large, however, you may not be able to on your iPhone. But that changes in iOS 13, which finally gives control over cellular data downloads in the App Store.
The long-awaited Dark Mode may have grabbed all the spotlight with iOS 13, but Apple has made subtle changes across the whole platform to make your iPhone even more user-friendly. A small option aimed at people who are sensitive to motion is one such example — a feature that can also be a godsend for the rest of us.
Learning Chinese is hard, but it can be a lot easier with the help of a few great apps. As a native English speaker who's currently living in China, this is a process I've recently gone through. After playing the field, here are the three apps I personally think will help you the most with your Chinese learning adventure.
At long last, the magical world of Harry Potter has received a mobile game worthy of its name. Harry Potter: Wizards Unite is the game in question, and is set to touch down worldwide on June 21, 2019. For the longest time, however, the game has been available as a soft launched game for testing, and with a little tinkering, you can actually try it out right now before its official release stateside.
