A relay is an electrical component that works like a light switch, where it's turned on or off with an electrical signal. By connecting a relay to a Wi-Fi connected microcontroller like an ESP8266, you can build a connected switch that can be controlled from the web browser of any device connected to the same Wi-Fi network — all for just a couple of dollars.
The war on dehydration is a commercially burgeoning marketplace. An increasingly sophisticated consumer population hoping to conquer everything from 26-mile marathons to vodka shots is deconstructing every functional remedy in the fight to quell the effects of severe dehydration.
Many guides on Null Byte require using the Secure Shell (SSH) to connect to a remote server. Unfortunately for beginners, learning to use SSH can become a confusing mix of third-party programs and native OS support. For Chrome OS users, using SSH is even more difficult. We'll fix this by using the Chrome Secure Shell to establish an SSH connection from any device that can run a Chrome browser.
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.
The iPhone X was released in November 2017, and the iPhone 8 and 8 Plus dropped right before it, but the hottest news right now revolves around the 2018 iPhone releases. The rumor mill regarding the iPhone X's successor started churning out speculations on names, cameras, display size, and more almost immediately after last year's devices, and there have been many new leaked details since.
Kylo Ren, conflicted villain of the new Star Wars trilogy, will surely be a major presence again this Halloween, with The Last Jedi fast approaching.

Since its debut, retro thriller Stranger Things and its characters have become ingrained in our popular culture — especially the telekinetic Eleven. For cosplayers, it didn't take long before they grabbed their boxes of frozen Eggo waffles, blonde wigs (or bald caps), and pink smocked dresses to transform into El herself.
A new technological movement without the technology itself is just an idea sitting and waiting. Once the technology is present in the equation, movement forward can begin. This is how many of us see the head-mounted displays (HMDs) and smartglasses that have recently entered the augmented and mixed reality market — or are coming out in the next few months. This is a movement that will sweep over the world, changing everything in its path, and these are some of the people behind it.
The Raspberry Pi is a credit card-sized computer that can crack Wi-Fi, clone key cards, break into laptops, and even clone an existing Wi-Fi network to trick users into connecting to the Pi instead. It can jam Wi-Fi for blocks, track cell phones, listen in on police scanners, broadcast an FM radio signal, and apparently even fly a goddamn missile into a helicopter.
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.

It’s called Urophagia—the art of consuming urine. There could be any number of reasons for having the desire to drink your own urine (or somebody else’s). There’s the so-called term “urine therapy,” which uses human urine as an alternative medicine. In urine therapy, or uropathy, it’s used therapeutically for various health, healing, and cosmetic purposes. There’s also those people who drink urine as sexual stimulation, where they want to share every part of each other. And then there’s the o...

After adding full-body tracking and 3D body mesh in its past two Lens Studio updates, Snap continues to supply creators, particularly apparel retailers, with tools for creating clothing-centric AR experiences.
With fears over the COVID-19 pandemic subsiding, live concerts are returning. And Doritos wants to send music fans to a few of them via an augmented reality promotion.
The realm of science fiction isn't all lasers and cute green toddlers, sometimes alternate science history is sci-fi, too, as exampled by the Apple TV Plus series For All Mankind.
Like the layers of an onion, 2021 continues to peel back new hints of Apple's kinda-secretive augmented reality device development.
Rumors of Apple developing smartglasses have persisted as prophecy since 2016, but the arrival of what many herald as the savior of augmented reality have eluded even Nostradamus himself.
If the interconnected worlds of blockchain, Bitcoin, and cryptocurrencies scare you a bit, you're not alone. Thanks in part to the extreme and seemingly random fluctuations in the value of Bitcoin over the past three years, more than a few developers and investors are wary of the cryptocurrency revolution and its ties to blockchain development.
MIT artificial intelligence researcher Lex Fridman recently asked SpaceX and Tesla founder Elon Musk possibly the best question he's ever been asked: What would he ask a hypothetical AGI system (an AI system with human-level intelligence and understanding) if he only had one question?
Reconnaissance is one of the most important and often the most time consuming, part of planning an attack against a target.
SMB (Server Message Block) is a protocol that allows resources on the same network to share files, browse the network, and print over the network. It was initially used on Windows, but Unix systems can use SMB through Samba. Today, we will be using a tool called Enum4linux to extract information from a target, as well as smbclient to connect to an SMB share and transfer files.
Passwords on Windows are stored as hashes, and sometimes they can be tough to crack. In certain situations, though, we can get around that by using the hash as is, with no need to know the plaintext password. It's especially interesting if we can manage to get the hash of an administrative user since we can then authenticate with higher privileges by performing an attack known as pass the hash.
When I first found out about Nreal, back in the spring of 2018, the most interesting thing about the company's story was the founder's background. Chi Xu, the CEO and founder of Nreal, previously worked at Magic Leap as a software engineer.
Information gathering is one of the most important steps in pentesting or hacking, and it can often be more rewarding to run things on the target itself as opposed to just running scripts against it remotely. With an SQL injection, a hacker can compromise a server and, ultimately, upload and run the "unix-privesc-check" script locally in order to further identify possible attack vectors.
With a simple social engineering trick, sudo passwords can be captured in seconds without the target's knowledge. The passwords can then be saved to a file or exfiltrated to another computer on the network.
The last time we heard from Meta, the makers of the Meta 2 augmented reality headset, things looked pretty bleak. Now, as several new facts have come to light, we have confirmation regarding the beleaguered company's fate: Meta is done.
Besides the Apple vs. Samsung competition, few battles are as vocal as the battle between the best Pixel and best iPhone. This year, it's the Pixel 3 XL and iPhone XS Max, two phones that are equipped with minor hardware updates from their predecessors, though both showcase significant OS-level improvements.
Continuing our NR30 series this week, we focused on the leaders of the software development industry that make augmented reality experiences possible. In other news, two of the current leaders in making AR headsets, Microsoft and Magic Leap, are pursuing multiple verticals with their products, as both now appear to be interested in making AR headsets for the military.
Apple released the fifth developer beta for iOS 12 on Monday, July 30, only 13 days after the release of dev beta 4 and 12 days after public beta 3. Until this release, Apple kept a consistent two-week schedule for developer beta updates, so we were a little surprised to see this one drop one day early.
As the official release of iOS 12 nears closer each day, Apple continues to update its betas. The company released the fourth beta of the upcoming software to developers Tuesday, July 17, exactly two weeks after the release of the third developer beta which came out just a few days before the second public beta.
Database technology has vastly improved the way we handle vast amounts of data, and almost every modern application utilizes it in one way or another. But the widespread use of databases naturally invites a slew of vulnerabilities and attacks to occur. SQL injection has been around for awhile, and as such, there are many defense methods in place to safeguard against these types of attacks.

On the airplane, in the middle of cold and flu season, your seatmate is spewing, despite the clutch of tissues in their lap. Your proximity to an infectious person probably leaves you daydreaming (or is it a nightmare?) of pandemics and estimating how likely it is that this seatmate's viral or bacterial effusions will circulate throughout the plane and infect everyone on board.
If you have a taste for sweets, you have at least one thing in common with mosquitoes. While too much sugar is unhealthy for humans, a new product makes sweets deadly to mosquitoes.
Food is both a necessity and a joy. Many people enjoy exploring, cooking, eating, and learning about foods from around the world. But the picture isn't always rosy. A new report from the Centers for Disease Control and Prevention (CDC), highlights the ways and whereabouts of food that make us sick.
