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.
Being able to write your own hacking tools is what separates the script kiddies from the legendary hackers. While this can take many forms, one of the most coveted skills in hacking is the ability to dig through the binary files of a program and identify vulnerabilities at the lowest level. This is referred to as binary exploitation, and today we're going to check out a tool known as Protostar.
Apple's latest mobile operating system, iOS 9, may not be the huge overhaul that iOS 8 was, but that doesn't mean there aren't plenty of new features. In fact, there are a ton of subtle changes that you may not notice right away. Here's a rundown of all the coolest new features you need to know about on the new iOS 9 for iPad, iPhone, and iPod touch.
When they first appeared, smartphones came with a promise to make our lives easier and make us more productive so we could have more free time and energy. But now, the average user spends almost 5 ½ hours daily on their smartphone. If that sounds like you, there are ways to use your iPhone more efficiently — without getting sucked into distractions.
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.
Apple doesn't include its Calculator app on the iPad and never did. One almost appeared over 12 years ago but was nothing more than a blown-up version of the iPhone app. Since then, the company still hasn't made an iPad-optimized calculator, and there is no shortage of third-party alternatives to fill the gap. It may happen one day, but for now, these are the best calculator apps for your iPad.
I've covered augmented reality apps for about three years now and the most useful mobile app I've encountered over that time is Google Lens.
According to a study done by Kaspersky, 7.6% of Android users root their phones. That may not sound like a lot, but with over 2 billion Android devices out there, the math works out to over 150 million rooted phones — more than the total population of Russia, Mexico, or Japan — so root nation is an important demographic that deserves being catered to.
On April 26, 2019, Sinemia posted a note on its website stating it has ceased all operations in the United States. It's not known if it continues to work in other countries or if US users will be getting any refunds, particularly, for annual subscribers.
There are more than a few subscription-based movie streaming apps available for Android and iPhone, each with different benefits and varying pricing plans. Needless to say, it can get expensive fast if you sign up for multiple services because you can't decide on what's best. Hopefully, we can help you out with choosing the right video-on-demand app to spend your hard-earned dollars on.

Mechanical locks have been around since ancient Egypt, with the oldest known artifact found in the ruins of Nineveh, an ancient city in Assyria, Mesopotamia, which is just across the Tigris River from what is now Mosul, Iraq.
SCRABBLE. To some it's just a game, but to me it's life or death. Well, not really, but it feels that way anyway. On a normal weekend, a game becomes much like Jon Thomas' "friendly game of death Scrabble."
With iOS 18, you get better note-taking capabilities in the revamped Notes app, advanced features like conversions and results history in the more powerful Calculator, and interactive Math Notes, a feature in both apps that's a game changer for students and professionals dealing with complex equations. But Apple didn't forget about Reminders, which has become more than a simple to-do-list app.
Apple Notes may not have all the bells and whistles that a more powerful word processor like Apple Pages has, but this simple text editor continues to gain helpful new features that make it more than just a basic note-taking app. One of these updates finally gives you the ability to highlight text and change font colors, adding yet another way to make important details stand out.
The latest iPhone update introduces big features like Live Activities and Clean Energy Charging, but those aren't the only things you'll notice different on iOS 16.1. If you build your own shortcuts in the Shortcuts app, there are a few things you'll definitely want to know about the new software. It's not a massive feature drop as with iOS 16.0, but they are important changes.
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.
While obvious, it's a lot more difficult to hack into a locked computer than an unlocked computer. As a white-hat hacker, pentester, cybersecurity specialist, or someone working in digital forensics, there's an easy solution — make it so that the computer won't fall asleep and lock automatically in the first place.
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.
Working with people in different time zones can be difficult when scheduling a time to meet up virtually, whether it's on Zoom, FaceTime, another video chatting app, or just a good old-fashioned phone call. The time needs to be good for all parties, and trying to remember UTC offsets and doing mental math isn't easy. Luckily, there's an easier way to deal with time zones on your iPhone.
While our time with the Protostar VM from Exploit Exercises was lovely, we must move on to bigger things and harder challenges. Exploit Exercises' Fusion VM offers some more challenging binary exploitation levels for us to tackle. The biggest change is that these levels are all network services, which means we'll write our first remote exploits.
When it's time to calculate a tip at a restaurant or bar, I usually try some mental math at first, but sometimes I resort to opening the Calculator quickly from the Control Center on my iPhone and doing a quick calculation. But with Apple's Shortcuts app, there's an even easier way, and you don't even have to leave your lock screen to get the results.
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.
Besside-ng is the hidden gem of the Aircrack-ng suite of Wi-Fi hacking tools. When run with a wireless network adapter capable of packet injection, Besside-ng can harvest WPA handshakes from any network with an active user — and crack WEP passwords outright. Unlike many tools, it requires no special dependencies and can be run via SSH, making it easy to deploy remotely.
Apple has released and continues to test 2024's major software updates for iPhone, iPad, Mac, Apple Watch, Apple TV, and Apple Vision. But are your devices compatible? Will you need to upgrade a device or two to get all the latest features? Find out here.
The Calculator app is probably one of Apple's most-used iPhone apps, yet I always meet people who don't know all the little tricks there are to using it more efficiently. You may know most of them, but there's a chance you don't or at least forget about some of them.
It hasn't been long since Apple released iOS 16.0 with over 350 new features, but iOS 16.1 just came out with even more cool updates for your iPhone. While some of the recent upgrades were expected, others are somewhat surprising — and there's even one that you may not even think was possible.
Apple made significant improvements to its Shortcuts app in the latest iOS update, so you can do even more with your custom-made macros for iPhone.
Apple's just ushered in a new era for widgets on your iPhone. With the iOS 16 update, each of your lock screens can have up to five widgets. While Apple's apps were the first to get lock screen widgets, third-party developers can code their own ones into their apps — and here's a list of every app we know so far that does.
Individually addressable LEDs, also commonly called "NeoPixels" after the popular Adafruit product, are a bright and colorful way to get started with basic Python programming. With an inexpensive ESP8266 or ESP32 microcontroller, it's easy to get started programming your own holiday lighting animations on a string of NeoPixels with beginner-friendly MicroPython!
LONDON: Bad at maths? Gorge on chocolates before you attempt your next examination. A new study has revealed that eating chocolate could improve the brain's ability to do maths as well as boost your energy level.
Nick Reade is here to help Videojug show you how to do a maths magic trick. What's a maths magic trick? watch and find out, but I bet it has something to do with numbers! Do a mathematical card trick.
This video demonstrates how to do a math trick. This is a fun way to teach children basic math and multiplication. Do a math trick.
For someone who loves math as much as Vi Hart (a self-proclaimed "mathematical musician"), she doesn't pay an awful lot of attention to her math teacher. But that's ok. Cuz somehow her wonderfully whimsical doodling transforms into mini lessons on graph theory, mobius strips, binaries, fractals and more.
Adding and subtracting may be the easiest of mathematical operations, but once you get it down, multiplication and division can be just as easy. That's why it's called elementary arithmetic. If it were harder, it would be called college algebra or trigonometry. But it's not— it's basic math, and once you get your head around the numbers, you'll never hate math class again! (Okay, maybe you will.)
This instructional video from BaseballRox will help you develop your outfield mechanics with outfield drills in the sport of baseball.

What is fractal? Well, it's a geometric shape which sometimes is hard to draw but looks very nice. There are some fractals which are easy to draw for example Koch snowflake or Sierpinski triangle:
Math is unreasonably effective in describing the natural universe. Anyone who's seen Walt Disney's Donald in Mathmagic Land knows this to be so. Well, the axiom works in reverse, too: The physical stuff of the universe can model math right back. And to great effect.
Math class got you down? We all know sixth grade mathematics is where we all start to lose it. We get frustrated with all of those numbers, try to figure it out, but ultimately flunk out or barely pass the class. Maybe the teacher just wasn't good enough to educate us, who knows, but there's no worries anymore.
Look for a vertical or horizontal relationship in the given equation. In the horizontal or vertical side of the equation where both numerator and denominators are given, look for a multiplier to the smaller number so that the product is equal to the bigger number. Use this multiplier to multiply it with the smaller number on the other side of the equation and you will get the value of "x".
