Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.
Puzzle games are great at giving your brain a workout while keeping things fun and killing time. They stimulate your noggin as you strategize and plan your next move, whether it's to keep your character from getting killed, or to get that special item to finally complete your collection and unlock a new feature within the game.
Throughout this NR50 series, we have talked about the incredible growth the augmented and mixed reality space has seen in the last year. More devices, software, developers, and use-cases seem to arrive daily. For this growth to have occurred, it took the work of many people, from many different backgrounds and skill sets — and Next Reality wants to recognize them for all that they have done and are doing.
Most of us skip through documents like privacy policies and EULAs (end-user license agreements) because they're long and boring. But, as Congress just passed the SJR34 bill in early April, you're probably a little concerned about your personal data, so we summarized the privacy policies for major ISPs and mobile carriers in the US.
If you're one who enjoys a good DIY project, or if you're just tired of paying exorbitant labor fees to have your vehicle serviced every 5,000 miles, changing your own oil can be a rewarding endeavor. Even though cars and trucks are becoming increasingly over-engineered these days, manufacturers generally see to it that the basic maintenance items can still be taken care of in your driveway with a few common tools.
Making a good pie crust can seem intimidating to the uninitiated, but once you master this skill, a whole world opens up to you. Not only can you make all manner of fruit, custard, and cream-filled pies once you know all the tricks, you can branch out into the world of quiches, savory pies, and flaky, crispy turnovers, too. We've already told you how to get perfect, firm fruit pie fillings, so now, let's learn about crust.
Cryptography is the science of keeping secrets, or more specifically, the science of disguising them. As a point of fact, cryptography has progressed quite a bit farther and now encompasses file and message integrity, sender authentication, and pseudo-random number generators.
It's super easy to add filters, adjust levels, and crop images using the default photo editor on your smartphone, but there's rarely any built-in tool for removing the background in a photo. A third-party app can help isolate people and objects in your pictures, and we've found a free one that's easy to use, works with high-resolution images, and is available for Android, iOS, iPadOS, and the web.
Unless you have unlimited cellular data, you probably connect your iPhone to every Wi-Fi network you come across. It could be a local coffee shop, public library, or just a friend's place. Wherever it is, you'll need to ask for the access point's password if it's a secured network, and that can be a hassle if the place is busy or the owner forgets the credentials. Luckily, Apple has a solution for this problem.
After the dust settled from Apple's annual iPhone event, there's not a lot to get hyped up about the iPhone 13 lineup, particularly if you upgraded your smartphone last year.
Brands are increasingly adopting augmented reality to promote their products and services, and they have multiple paths for bringing AR experience to their audiences.
While Snap may eventually compete with Apple and Samsung in selling smartglasses to consumers, today it is helping them achieve their business objectives via augmented reality.
Sure, Microsoft has mostly marketed its HoloLens headsets towards enterprises and developers, but we learned this week that, like every other tech giant, the company is working on a consumer-grade AR wearable. Speaking of consumer smartglasses, Apple made another strategic investment this week that has implications for Apple's AR future.
The augmented reality industry has grown steadily over the past four years, but now it is on a collision course with uber-popular non-fungible tokens technology, with Looking Glass and music artist Reggie Watts among the latest to strike while the iron is hot.
The economic impacts of the COVID-19 pandemic have been felt in practically every business sector. Now, as we look back at the top augmented reality investments of 2020, the AR industry has been no exception.
One of the most aggravating things that can happen on Facebook, Twitter, and other social media apps is when a friend shares an exciting story, and a paywall prevents you from reading any of it. You could pay for a subscription to unlock it, but there are so many news sites that it can be both confusing and expensive to spend money on all of them.
In the realm of social media, all roads lead to one destination: cracking the code of continuous partial attention dopamine hits. We learned this back in the days of Vine, before Twitter foolishly killed it. And I pointed my lens at the emerging trend back in 2016 when I highlighted Musical.ly for Mashable, just before it was snapped up by China's Bytedance for $1 billion and merged into what is now TikTok.
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.
You can mod every aspect of your phone's software with root, but if you want to make changes at the hardware level, you'll need a custom kernel. If you've looked into custom kernels before, one name undoubtedly kept coming up: ElementalX. It's easily the best custom kernel out there, and the reason for that is its awesome developer, flar2, aka Aaron Segaert.
It is almost indisputable that smartglasses and head-worn displays are the future of augmented reality. However, at this precise moment, they are still a very niche market.
Contrary to popular belief, augmented reality apps have been available for a while now. I remember using the Layar app (still available for iOS and Android) to explore nearby businesses and landmarks with varying success via an early-generation Android handset.
With an ordinary birthday card, we can introduce a physical device which contains malicious files into someone's home and deceive them into inserting the device into a computer.
Around this time in 2016, the predictions for the next year had reached something of a consensus: 2017 would be the year of augmented reality. But a funny thing happened on the way to the future — nothing much, really. At least not for the first half of the year.
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.
Andre was enjoying the carefree life of a 12-year-old with his friends, riding his bike and playing sports, like all kids that age. Schoolwork wasn't hard for him, and his grades showed that.
On July 20, 1969, humans set foot on the moon for the first time. But some say our microbes beat us there. With the Space Age came new questions about microscopic invaders from outer space and concern about where we are leaving our microbial footprints. The questions are even more relevant today.
Welcome back Hackers\Newbies!
A vending machine is an invaluable yet totally frustrating piece of equipment. It's a godsend whenever your tummy's growling or you need an ice-cold drink on a hot summer day. But when something gets stuck inside or the machine flat-out malfunctions, it quickly becomes your archenemy. And when you're broke, it's basically just one big tease.
Thanks to rapid advancements in the field, generative AI can do some amazing things already, from generating text, images, and video with just a prompt to automating tasks and developing new products and services. Now, artificial intelligence can even help you craft emails directly in Gmail.
The iPhone 13 and iPhone 14 series models have a new feature on iOS 16 that lets you use Face ID when your iPhone is in landscape orientation. This is most helpful when trying to make purchases in apps and games where you use your iPhone rotated on its side. If you're having issues using Face ID in landscape mode, there may be some easy solutions to getting it working.
Night Shift, Dark Mode, Reduce White Point, and Zoom's Low Light Filter all help reduce the harmful effects on your body's clock that bright iPhone and iPad screens have at night. But there's another option on iOS and iPadOS that turns your entire display red, and it's useful for so much more than just late-night browsing in bed.
There are two types of people in this world: those who recognize Wordle grids of yellow, green, and gray/black blocks and those who do not. No matter which category you fall in, there's a Wordle-inspired game that's perfect for you.
Some phone lines make it nearly impossible to get past the busy tone, whether it's a viral call-in giveaway, your state's unemployment office, your local post office during the holidays, or the repair office for a broken warrantied product you have. Thankfully, there are apps you can use to help break through the noise.
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.
Facebook's annual earnings call on Wednesday didn't come with any big surprises, that is, if you took everything at face value.
If you buy an Android phone from any of the big US carriers, it will come with several extra apps in addition to any apps the manufacturer preinstalled. It's all in the name of profit, of course. Some of these apps are from companies that paid the carriers to distribute their software, and some are from the carriers themselves, usually aimed at upselling you or perhaps collecting a little data.
The Metaverse, or AR cloud, has been a sci-fi dream for decades, but only recently have companies begun to actually develop the technology to build it. With its latest funding round, Epic Games is suddenly a front-runner in this pursuit.
Streaming media companies like Netflix and Hulu make deals with Roku to have their apps featured on Roku's remote controls, but there's an inherent flaw with this model: the buttons become useless if the app no longer exists. So, is there anything you can do to change those defunct buttons on your Roke remote?
Most packages sent to you via delivery services include a tracking number that allows you to track it from the creation of the shipping label all the way to your doorstep. The U.S. Postal Service includes tracking information with many of its mailing services, but not for first-class mail or periodicals. Luckily, there's a workaround to that limitation that you can set up pretty quickly.
If you'd rather be gently relaxed out of bed instead of stressed out at loud alarm sounds, there are a few things you can do on your iPhone. One of your best options is to use carefully selected songs that start out calm and soothing and gradually increase in intensity and volume. But you could also use a more intense track you know will wake you up, only set to ascend in volume to ease you out of slumber.
