If you want to learn how to get and graph the slope of a line using two points, you should watch this. 1. Let your two points be (x1 , y1) and (x2 , y2). Draw a straight line that connects the two points. 2. Use the formula, m = change in y over change in x , for finding the slope which is represented by the variable m. 3. The simpler form of the formula would be m = (y1 - y2) / (x1 - x2). 4. If you were given two points, just substitute the values in the given formula. 5. For example, the tw...
In this economy being competitive for a job means your application must stand out above the rest. Here's how to write a cover letter to successfully introduce your resume. Make sure your cover letter follows business letter format. Your name and address must be written at the top left corner. The employer's name and address are written just below.

Popping a shell is often the main goal of a hacker, and it can be exciting when executed properly, but sometimes they do have their limitations. Metasploit's Meterpreter probably needs no introduction, but this powerful, dynamic payload can offer a leg up over normal shells. To prove it, we'll show how to take a normal command shell and elevate it to a Meterpreter session.

There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this part, I'm actually going to tell you more than just how to make a crystal radio, but I'm also going to explain how and why they work. Crystal radios are pretty Steampunk in and of themselves, since they were first developed in the late 19th centu...

UnrealIRCd is an open-source IRC server that has been around since 1999 and is perhaps the most widely used one today. Version 3.2.8.1 was vulnerable to remote code execution due to a backdoor in the software. Today, we will be exploiting the vulnerability with Metasploit, examining the underlying code to understand it, and creating our own version of the exploit in Python.
After the first image leaked of the upcoming successor to the Razer Phone, many were taken aback by its design, specifically how familiar it was. Last year's Razer already stood out with its boxy design and large bezels, and many thought the successor would change this. It didn't. But what if the reason for the familiar form factor is a project they teased earlier in the year?
One of the primary marketing tactics used by Magic Leap in promoting the Magic Leap One was selling early adopters on the "magic" contained within the device. On Thursday, some of that magic was uncovered as the Magic Leap One was completely disassembled by repair engineers, revealing the delicate innards of the device and detailing how it delivers its augmented reality experiences.
Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.
Welcome back, my rookie hackers! So many readers come to Null Byte to learn how to hack Wi-Fi networks (this is the most popular hacking area on Null Byte) that I thought I should write a "how-to" on selecting a good Wi-Fi hacking strategy.
The guide will walk you through a power switch replacement on a bObsweep Standard or Pethair. It includes:
War leaves a lot of stuff behind. Torn families, delegitimized institutions, mass graves, and unexploded ordinances litter the post occupation landscape. Whether or not you have driven the imperialist out, or are still in the phase of armed resistance, you will need the ability to safely diffuse bombs. My bomb defusing Silvia-bot can do it all. She can catch grasshoppers, cut wires, collect samples, tase enemies and even play chess! Materials
Automatic phone menus are the worst. You call the number, listen to prerecorded prompts, press button, listen, press button, listen, press button, listen, until you're routed or connected to the right extension, directory, menu, person, or whatever. But you can bypass these automated attendants to get right to where you need to go by setting up a simple shortcut on your iPhone.
At first, it seemed like a clever art installation housed on the web, but now we're not so sure... the Newstweek hack may indeed be legit.

On Thursday, Osterhout Design Group (ODG) revealed a new, specially-crafted oxygen mask that uses the same augmented reality technology from its smartglasses to assist FedEx Express pilots navigating dangerous conditions.
Historically, Apple loves to drop hints about its major upcoming events through clues included on its invitations. Those invites usually require a good bit of deciphering to connect the dots, but in the case of Apple's upcoming Worldwide Developers Conference (WWDC) 2018 invite, the topic is immediately obvious: it's augmented reality.

The threat of an evil access point has been around for a long time, and with the rise of open public Wi-Fi, that threat is often overshadowed by how comfortable we are using third-party Wi-Fi hotspots at coffee shops and public spaces. While we've shown an evil twin attack using the Aircrack-ng suite of tools, MitmAP is a Python tool to configure custom APs for many types of wireless attacks.
Just weeks after previewing its smartglasses in a pair of videos, augmented reality hardware maker Vuzix announced on Friday that pre-orders are open for Vuzix Blade developer kits.
As a long-distance runner off and on for the past, I absolutely detests hills. While there are many apps that can measure elevation and slope for certain routes, understanding spatial data on a line graph or even an elevation map can be difficult.

I want my Halloween costume to take as little effort as possible and be cheap—extremely cheap. That means I don't want to pay 50 bucks for some costume online or spend all day playing with liquid latex, and I most definitely do not want to visit a super crowded costume store in Hollywood.
If you don't have a car, or just prefer to take public transit to work, you know that an unexpected change in the weather can quickly...er, dampen your day. If you're not expecting it, rain or snow can turn your trip into a long, hellish ordeal—especially if you bike.
