In this video the author shows how to do similarity transformations. He says that similarity transformations are used to draw the similar images at a different location and the k value is most important while doing this kind of transformation. He says that a negative k value tells that the copy of the shape will end at the opposite side of the origin to the original shape. He says that a positive k value tells that the copy will lie on the same side of the origin. Next thing about the k value...
The video describes the basic process of multiplying two rational expressions. The problem illustrated in this video involved multiplying rational expressions of monomial terms with integer coefficients. As with the other example problems, we follow the steps of: factoring, canceling, and multiplying. Because these terms are monomials, no factoring is required (but we still state it as a step for similarity to solving other problems). We then find the greatest common divisor for both terms to...
Apple is no stranger to lawsuits. They were in a decade-long battle with Samsung that finally came to an end last month, and they've been duking it out in the courtroom with Qualcomm since last year. The more recent case has seen both companies file suits and counter-suits, but now, Qualcomm is claiming that Apple's new iPhone X infringes on patents from a long-deceased mobile operating system.
Google and Samsung have been leaving Apple in the dust when it comes to virtual reality gear. However, as the market grows and becomes more impossible to ignore within the tech world, Apple may be forced to play catch up. This could account for the new Apple patent that was granted today.
Yesterday, April 7th, it was revealed that the United States White House had been hacked by allegedly Russian hackers. According to reports, the Russian hackers used social engineering/phishing to get a foothold in the U.S. State Department and then pivoted from that system/network to the White House. Although the White House said no confidential information was compromised, the President's appointment calendar and other information were. Attribution or "blame" for the hack was made more diff...
Right off of the unveiling of the Moto Z2 Play, it looks like Lenovo is gearing up to announce the highly anticipated Moto Z2.
In case Google Photos didn't recognize your face enough, they're now rolling out a new AI feature who uses facial recognition for easy photo sharing.
Is "Last Resort" Steampunk? Well, no. I mean, how could it be?
During Huawei's P30 smartphone launch event on Tuesday, the China-based company unveiled a surprise addition to its line-up: smartglasses.
Crusty, itchy, red eyes? There is a decent chance you could have conjunctivitis, or pink eye, an infection of the thin lining around the eye and the eyelid, caused by bacteria, an allergen, virus, or even your contact lenses. Whatever the cause — you call up your doctor to get a prescription to clear it up, right? Not really.
More than one in ten people in the US have type 2 diabetes — that's over 29 million people. It's characterized by excessive sugar (glucose) in the blood due to the development of resistance to insulin, the hormone that normally metabolizes glucose.
As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists believe that gut bacteria may have a role in initiating the abnormal immune response. Now, a team of researchers from Boston has figured out how that might occur.
The Deepwater Horizon oil spill that began on April 20, 2010, was the largest maritime oil spill in history. Killing 11 people and discharging 4.1 million barrels of oil and natural gas into the Gulf of Mexico, the event was an unparalleled personal, environmental, and business disaster. It was also the first major oil spill to take place in the deep ocean.
Sometimes it's impossible to concentrate — let alone direct your personal assistant Siri — when someone is blasting music on their phone or talking to thin air. I mean I'm loud, but not that loud.
Have the sniffles? Yes. Does your head hurt? Yes. Coughing? Yes. Could you have influenza? Yes. How do you know the difference? With these symptoms, you could also have a cold.
Welcome back, my novice hackers! As many of you know, recon is crucial to a successful hack/pentest. In most cases, hackers spend more time doing good reconnaissance than actually hacking. Without proper recon, you are simply guessing at what type of approach or exploit is going to work and, as a result, your time is wasted without any useful outcomes.
There are tons of greasy drippings that can be used to flavor up any dish, but none will ever be more delicious than animal fat. The bigger and fatter the animal, the juicier and tastier their fat is. For those of you who have had your fill of bacon-anything, here's your next obsession. It's called caul and its very existence will divide those that are serious about their animal fat flavoring from the pretenders.
The concept and structure of Christmas hasn't changed much since its inception. In its infancy, Christians recruited Roman pagans by associating Christmas with the Saturnalia, an ancient Roman festival in honor of the deity Saturn (also held in December). The pagans had long worshiped trees (as did other historical cultures) and would bring them into their homes and decorate them, something that influenced our modern holiday decorations. While certain things such as gifts and ornaments have b...
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.
A convincing domain name is critical to the success of any phishing attack. With a single Python script, it's possible to find hundreds of available phishing domains and even identify phishing websites deployed by other hackers for purposes such as stealing user credentials.
Google just bought a huge chunk of HTC for $1.1 billion. They're bringing in around 2,000 employees, mostly from the hardware division, and these folks will presumably work under hardware chief Rick Osterloh. There's a massive patent portfolio involved, too, so stop me if you've heard this before — Motorola, anyone?
The augmented reality smartglasses race is getting a major new entrant that could significantly change the entire landscape.
Following the launch of the Magic Leap One earlier this month, the device and the company took a few hits from early reviewers. But it turns out those were just love taps compared to the absolute scorched earth acidic screed penned this weekend by someone well credentialed to dissect Magic Leap One: Oculus Rift creator Palmer Luckey.
A router is the core of anyone's internet experience, but most people don't spend much time setting up this critical piece of hardware. Old firmware, default passwords, and other configuration issues continue to haunt many organizations. Exploiting the poor, neglected computer inside these routers has become so popular and easy that automated tools have been created to make the process a breeze.
Kuru is called the shaking disease, its name derived from the Fore word for "to shake." Caused by an organism that infects the part of the brain that controls coordination, people afflicted with kuru shake uncontrollably.
After enabling disk encryption, creating encrypted disk images, installing KeePassX and iTerm2, and using Git with local repositories, the next step to getting your Mac computer ready for hacking is setting up a package manager that can install and update open-source hacking tools. There are multiple options to choose from, but Homebrew has a slight advantage.
You can find chili peppers in practically every cuisine. From the sweet Italian variety to the spicy Thai bird's chili and the smoky Mexican chipotle, peppers are ubiquitous and universally loved. But if you find the range and scope of these little fireballs overwhelming, you're not alone.
OnePlus will be releasing a new phone in the second half of 2018, specifically, an upgrade to their T-series. Over the past two years, #T versions have come out about five months after their predecessors and have included small updates that fix any problems from the previous OnePlus device. While we do know a bit about OnePlus 6T, what it could be is much more exciting.
Clumsiness is the great equalizer when it comes to smartphones — it makes no distinction between the most expensive flagship handset and cheaper mid-range models. A hard drop onto pavement will usually result in a shattered screen, regardless of how pricey your device is. And with a smartphone breaking every two seconds, we're truly our own handset's ultimate nemesis.
The smartphone market is stagnating. Without hordes of new users rolling in every year, the best way to boost profits nowadays is to poach customers from the competition. That's exactly what Apple appears to be doing with iOS 14.
For many, phones are starting to replace televisions as the primary device for watching videos. Thanks to their portability and easy to use apps, it's often simpler to watch Netflix, Hulu, YouTube, or Prime Instant Video on the smaller screen. But not every phone is suited to fit this need, so we did some testing to find the best of the best when it comes to streaming videos.
The beehive is a woman's hairstyle that resembles a beehive. It is also known as the B-52, for its similarity to the bulbous nose of the B-52 Stratofortress bomber. It originated in the USA in 1958 as one of a variety of elaborately teased and lacquered versions of "big hair" that developed from earlier pageboy and bouffant styles. The peak of its popularity was in the 1960s, and it was especially popular in the United States and other Western countries. The beehive remains an enduring symbol...
Following in the footsteps of great historical figures is a great way to learn about them. Michael Wood famously did so in the 1980's for his PBS documentary and book In The Footsteps of Alexander The Great. This March, UK-based marketing director Chris Worth completed a similar endeavor—not by tracing the path of a real-life emperor or explorer, but a humble video game character. One known simply as "The Courier".
In Photoshop-speak, we call them faux-tographs. Michael Shermer presents this lesson in falsehoods as a children's craft project. Just tie up some kitchenware to an old fishing pole, flash the photo and ta-da! There's your err... evidence!
Hello, nubile young Photoshop explorers! As we all know, besides design, Photoshop is best used for revenge, as will be demonstrated below. This is my ex-girlfriend, Cassandra. She dumped me because I had "poor bone structure." I'll bone her structure! Well, not anymore, I guess.
How do we really come to the decisions that we make? Is it just flip a coin and hope for the best or is there some underlying procedure that we go through, consciously or unconsciously, that guides our course of action?
It's Monday, time to highlight some of the community submissions posted to the Math Craft corkboard. One of these posts inspired me so much, I think it merits a closer look. Today, I present a "simple" method for making a golden spiral using just a straight edge, a compass, and a template, inspired by RJ Ellicock's golden ratio post.
