Given a function, you can easily find the slope of a tangent line using Microsoft Excel to do the dirty work. That is to say, you can input your x-value, create a couple of formulas, and have Excel calculate the secant value of the tangent slope. This is a fantastic tool for Stewart Calculus sections 2.1 and 2.2.

"I want to make video games" — Is there anyone who hasn't ever thought that? It's almost universal among gamers to want to get on the other side of the screen and design the games themselves, especially those of us who have played less than impressive games and thought that we could do a better job. But it's hard to know where to start — or how — when it comes to creating our own games.
People are going nuts with their iOS 14 home screens. One look on social media shows just how creative people can be with their home screen widgets and customized app icons. That said, maybe you aren't looking for a crazy setup. Maybe you're someone who wants a simple, clean home screen. Friend, this trick is for you.
Those of us who've taken the time to learn how to code are relatively well-suited for shakeups in the economy. Despite the recent and notable disruptions caused by the COVID-19 outbreak, demand for talented and trained programmers and developers is still high, and it will likely keep rising as companies in every industry adapt their business models to a more remote world.
Penetration-testing frameworks can be incredibly useful since they often streamline certain processes and save time by having a lot of tools available in one place. Of course, the most popular pentesting framework is undoubtedly Metasploit, but there are many others out there that cater to particular needs. For auditing web applications and servers, Tishna comes in handy.
The automatic software update setting on your iPhone is nice, but you may not always want to install new iOS versions blindly. New updates could contain bugs and vulnerabilities, and your favorite features may even disappear. With the auto-update option turned off, you can manually download and install updates, but there are also hidden options to be more specific about how you want to do it.
Hacking web applications can sometimes be challenging due to the sheer amount of moving parts they possess. At the core of these apps are HTTP requests and parameters, but these things are often concealed from the user, due to security reasons, convenience, or both. However, a tool called Arjun can be used to discover hidden HTTP parameters in web apps.
With the Wigle WiFi app running on an Android phone, a hacker can discover and map any nearby network, including those created by printers and other insecure devices. The default tools to analyze the resulting data can fall short of what a hacker needs, but by importing wardriving data into Jupyter Notebook, we can map all Wi-Fi devices we encounter and slice through the data with ease.
Determining the antivirus and firewall software installed on a Windows computer is crucial to an attacker preparing to create a targeted stager or payload. With covert deep packet inspection, that information is easily identified.
Apple released iOS 13.4.1 to the public on April 7 but also pushed out the update for the new second-generation iPhone SE model on April 23, one day before the device's official release. The update fixes a FaceTime bug and Bluetooth quick action failure that appeared in iOS 13.4.
One vital part of Android 10's new navigation system is the "QuickStep" gesture. Swipe up from the bottom of your screen, then pause. You'll see your recent apps along with a dock containing a handful of icons for quick access. This dock is provided by the phone's launcher, which means your home screen is now integrated into the multitasking UI. So what happens if you change your home screen app?
Twitter can be a wonderful place for people to express their emotions and chat with each other in brief. However, it can also be a breeding ground for hateful comments, foul language, and a whole lot of political talk.
This week's Apple earnings offered a report of solid performance and guarded optimism about future iPhone sales, which may be impacted later this year by issues around the current coronavirus epidemic in China.
Using Apple Pay in stores to make purchases is as easy as holding your iPhone near the NFC reader and authenticating with Face ID or Touch ID. That method uses the primary payment card in Apple Wallet automatically, and your primary card may change from week to week based on your spending, so you'll probably need to change it periodically.
Web applications are a prime target for hackers, but sometimes it's not just the web apps themselves that are vulnerable. Web management interfaces should be scrutinized just as hard as the apps they manage, especially when they contain some sort of upload functionality. By exploiting a vulnerability in Apache Tomcat, a hacker can upload a backdoor and get a shell.
While the App Store is filled with news aggregators, Apple News is a solid choice when it comes to keeping up with current events. Apple recently made it easier than ever to stay informed, thanks to a daily newsletter sent straight to your inbox. The problem? It's unclear how to sign up for this newsletter, and it's equally unclear how to unsubscribe.
Apple seeded public testers the second beta for iOS 13.3 eight days ago. That update mainly added stability patches to iOS as a whole, as did the public releases of iOS 13.2.2 and iOS 13.2.3.

An iPhone updated to iOS 13 on Sept. 19 will only have 11 days before seeing 13.1 in its Software Update page on Sept. 30. To prepare for this release, Apple released the fourth iOS 13.1 public beta, just about the same time as its developer counterpart.
Apple's iOS 13 is nearly here. After four months of beta testing, the latest iPhone software update promises over 200 brand new features, like system-wide dark mode and an overhauled Reminders app. That said, it'll be shortlived, as Apple plans to release iOS 13.1 as a supplemental update just 11 days later.

After months of waiting, the iPhone 11 is here. At an event in Cupertino, Apple unveiled the iPhone 11, 11 Pro and 11 Pro max. You probably have a lot of questions after reviewing the specs sheet, including wanting to know more about the IP68 rating that all three phones have. We're here to clarify.
One of the first steps in attacking a web application is enumerating hidden directories and files. Doing so can often yield valuable information that makes it easier to execute a precise attack, leaving less room for errors and wasted time. There are many tools available to do this, but not all of them are created equally. Gobuster, a directory scanner written in Go, is definitely worth exploring.
NASA is going going to Saturn's moon Titan, and the space organization is using augmented reality help them do it.
Pandora has a simple rating system that works by hitting either the thumbs-up or thumbs-down icon on a track that's playing on your station. If you choose the former, the song you like along with others similar to it will play with more frequency, while selecting the latter will prevent that song and others like it from playing in your station moving forward.
From the first moments of booting up Harry Potter: Wizards Unite to the hours of walking you're bound to experience, one thing is clear — encountering Foundables and defeating their Confoundables is a significant plot point of the AR game. While you receive rewards each time you retrieve a Foundable, the real treasure comes from completing parts of the Registry, called "Families."

Open-source intelligence researchers and hackers alike love social media for reconnaissance. Websites like Twitter offer vast, searchable databases updated in real time by millions of users, but it can be incredibly time-consuming to sift through manually. Thankfully, tools like Twint can crawl through years of Twitter data to dig up any information with a single terminal command.
There are only three more episodes of Game of Thrones left before the saga is over, but Magic Leap is capitalizing on the series' popularity while it still can.
Is there a bigger name in pop music than Taylor Swift right now? Her 116 million followers on Instagram would probably argue, "No." As such, if you're one of these many followers, you might have seen Taylor advertising a new "4.26" filter on her story. Problem is, there's no clear instruction for actually using the filter. That's where we come in.
