Admit it: you've been caught muttering to yourself under your breath in very public places. Maybe you've gotten stares while wandering the grocery store talking to yourself out loud. If you're like me, you might even talk yourself through various tasks, giving the atmosphere a little background noise.
In today's dog-eat-dog world, every minute matters. Whether you're in school or working for the Man, a huge amount of your day is consumed by tasks, assignments, and other kinds of work. Then there's the time you spend playing video games, watching TV, or screwing around on your Samsung Galaxy S3.
Welcome, my neophyte hackers!
One of the most frustrating things on the Internet are sites that make you register just to view content. I'm not talking about paywalls—I mean the sites that make you give them personal information to look at free articles or forum threads. Most people are uncomfortable with this because a lot of these sites either spam you themselves, or sell your information to someone else who will.
In this video series, our expert Sean Hobson will show you how to run a 4-3 defense in american football. He will teach you how to position the linemen, the linebackers, and the defensive backs. Sean will teach you the job of each defensive position, and how to blitz using each position. He will even show you the gap and pass coverage assignment of each position so you'll be prepared for whatever the offense throws at you.
Procrastination is an ugly beast. At first, it seems so innocent to spend five minutes checking Reddit or Twitter. You'll get started on work right after. Next thing you know, it's 1 a.m. and that paper is due in seven hours. Before you start another YouTube video, know you don't have to be like Spongebob. You can be like me, taking control of your productivity with the right app.
Cleanliness is next to godliness. My interpretation of that age-old adage means that keeping your house clean is just as un-fun and boring as being a goody two shoes. That's why they call things like laundry and doing dishes "chores," I assume. Yuck.
Effective communicators are always in high demand in every industry. Whether your team is building the next billion-dollar app or you have a giant data set in front of you for filtering, communicating with your team is essential.
Niantic recently added a new Field Research task type called AR Mapping that challenges players to capture video footage of PokéStop landmarks and upload them. In return, players receive rewards in the form of in-game items.
You might be using Zoom on your iMac, playing a Steam game on your MacBook, or completing a work assignment on your iPad, when suddenly you get a phone call on your iPhone. If the same Apple ID is used on all of your Apple devices, the call won't ring on your iPhone only — it'll ring on every damned device.
When filtered through the prism of the top stories of the year, the business of augmented reality 2019 was defined as much by epic failures of AR startups as it was by the promising developments that propelled the industry forward into 2020.
A few long-awaited iOS 11 features that Apple had promised way back in June 2017 have finally made their way to iPhones with the iOS 11.4 update. Aside from finally delivering on those, there's not a whole lot new in iOS 11.4 as a whole, though, there are a few things you'll definitely want to know about.
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.
Greetings my fellow aspiring hackers,
Welcome back, my greenhorn hackers! As expected with Null Byte's dramatic growth over the last year, we have added many new aspiring hackers who are still lacking in the basics of networking. In addition, with the new "White Hat" certifications coming out shortly, the exam will require some basic networking skills and knowledge to pass.
Though many students spend four years of high school learning a foreign language, most of us probably retained very little. Chalk it up to the carelessness of youth, but chances are you've since been in situations or places that left you wishing you paid more attention in class or had continued practicing long after you graduated.
You have an assignment due, whether it's homework for school or a project for work, but you've only got a few hours left. There's no way you're going to finish in time and do a good job, and you don't want to turn in anything incomplete or half-assed. While it may seem you're out of luck, there's a simple way to buy yourself more time.
There are many ways to access the Google Assistant on your phone, but Android 12 adds another one for Google Pixel models that may be the best way yet.
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.
Can lightning strike twice? Niantic is betting that it can with its latest augmented reality game based on the best-selling multimedia franchise Harry Potter.
Auditing websites and discovering vulnerabilities can be a challenge. With RapidScan and UserLAnd combined, anyone with an unrooted Android phone can start hacking websites with a few simple commands.
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.
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?
Hey everyone. Only found the site a few days ago but really loving it. Been
With a cheap computer, smaller than the Raspberry Pi, an attacker can create a remote hacking device. The device can be attached to a target router without anyone's knowledge and enable the hacker to perform a variety of network-based attacks from anywhere in the world.
The one thing that separates a script kiddy from a legitimate hacker or security professional is the ability to program. Script kiddies use other people's tools, while hackers and security pros write their own tools. To that end, we're going to see how a stack overflow vulnerability allows us to flood a variable with enough input to overwrite the instruction pointer with our own commands.
Apple just seeded the fourth public beta for iOS 13 to software testers today, Tuesday, July 30. AppleSeed participants saw this beta one day early, alongside the release of developer beta 5. Now, developer and public testers alike are up-to-speed with the latest in iOS 13.
Beta testing for Apple's big upcoming iPhone update, iOS 13, is well underway. So far, each of the four beta versions we've seen brought new features and changes to the table, many of which were never even mentioned by Apple during WWDC in June. Now, it's time to do it all over again, as Apple just released the fifth developer beta for iOS 13.
The wait wasn't so long this time. Apple released public beta 3 for iOS 13 on Thursday, July 18, just one day after the release of developer beta 4. For context, Apple took five days to seed public beta 2 after releasing dev beta 3, so it's a pleasant surprise that the latest public beta dropped so soon.
We're pumped for iOS 13 and all of the fresh features and changes that come with it. Developer beta 3 came with new features in the double digits, including AR eye contact in FaceTime and mouse cursor size customization. Developer beta 4, released today, has a few more additions and changes as well.
The third developer beta for iOS 13 has been out since July 3, and while devs have had fun exploring all the new features, those of us on the public beta have sat on the sidelines running the public version of dev beta 2. But we don't need to wait any longer, as Apple just released iOS 13 public beta 2 and all the goodies that come with it.
On July 3, Apple pushed out iOS 13 developer beta 3 for iPhone, and there's a lot found hidden within. A new FaceTime setting, more Arcade details, full-page scrolling screenshots everywhere, a noise cancellation option in the Control Center, and a new markup tool — and that's just a few of the new features.
There's no doubt iOS 13 has dominated the talk around the Apple community this month. Since the announcement and release of the first developer beta, we iPhone users have had a treasure trove of new features and changes to explore and discuss. Now the fun continues with iOS 13 dev beta 2. Who's ready to start up the conversation all over again?
The first developer beta for iOS 13 is available to install on iPhone models, but the process for doing so may be a bumpy ride. Apple has not included configuration profiles for the developer beta yet, and many developers are having issues installing iOS 13 even with macOS 10.15 Catalina installed. Plus, since this is the first beta, there are a lot of problems with old and new features to work the kinks out of.
After a long hiatus, we shall once again emerge from the shadowy depths of the internet to build an exploit. This time, we'll be looking at how to defeat a non-executable stack by using the ret2libc technique — a lean, mean, and brilliant way of exploiting a stack overflow vulnerability.
When you want a helpful task manager on your iPhone or iPad, any of the nine apps in this guide should be at the top of your list. But we'll review each app's features to help you determine which one might be best for your workflow.
