Our expert, Branson Garner, will show you the basics of upright bass playing, including just figuring out what all the parts are called, how to make clear, precise notes, and how to maintain the bass and keep it in tune. For advanced players, he offers several lessons that can help expand your double bass playing into different styles and genres, as well as various techniques you can incorporate to add color and excitement to your basslines.
Before you can find the area of any geometrical figure, recall what you are finding when you solve for the area. The area is the surface of a 2-dimensional shape. When trying to find the area of a right triangle, the easiest way is to first double the triangle so that it resembles a square. This is particularly important if you don't know the length of the hypotenuse. Using the knowledge that the area of a square is the length multiplied by the height, calculate the area of the square you cre...
A bouquet of roses is a lovely thought but will quickly wilt and die. Give your loved one a bouquet of roses that will last for years to come and it will only cost you the price of a pencil and paper. They’re quick and easy to sketch.
When it comes to finding the exact moment you want to see in a video, the seeking function can be hit or miss depending on the streaming service you're using. On YouTube, though, it just got much better.
Apple added a great new feature to its Measure app in iOS 14, but it only works on the iPhone 12 Pro and 12 Pro Max models as of right now. If you have one of those models, you can now measure a person's height with accuracy within a few centimeters, whether they're standing or seated.
As you're surely aware, your phone can be used against you. Thanks to our cameras and microphones, a clever hacker can obtain access to your device and invade your privacy. But spying isn't limited to just these two sensors — gyroscopes, proximity sensors, QR codes, and even ads can be used to paint a very clear picture about who you are and what you're currently doing.
Tossing an old Android smartphone with a decent battery into your hacking kit can let you quickly map hundreds of vulnerable networks in your area just by walking or driving by them. The practice of wardriving uses a Wi-Fi network card and GPS receiver to stealthily discover and record the location and settings of any nearby routers, and your phone allows you to easily discover those with security issues.
Everyone has used a ruler at some point in their life, whether for art sizing, blueprint plans, or sizing up your widescreen television on your living room wall. But there's a lot of little ticks on the ruler that you may not be aware of. Your ruler shouldn’t be used only to draw a straight line. Make sense of all those little lines and take advantage of its intended use.
The video shows us how to find the area of triangles and other geometric shapes. First, before starting to find the areas, we need to know the basics of what do those shapes actually mean and we need a little bit of vocabulary to back us up. First, the parallelograms are four sided figures with two sets of sides which are parallel to each other. The rectangles and the squares qualifies the parallelograms and also the parallelograms except that they have slanted sides and the triangles are thr...
It doesn’t matter how long ago your last geometry class was, you can still impress your friends by finding a geometric mean. The geometric mean can be used to find the average of numbers with out unusually high or low results effecting the result.
This how-to video is about how to reduce belly fat with the help of a better diet.

When you listen to music, you don't just want to listen to your favorite songs and artists — you want to hear them perfectly. The same goes for videos you're watching, games you're playing, calls you're in, and anything else in which audio plays a key role.
For a long time, digital creators have had to make do with clumsy mice that don't capture the minute movements they need to do their best work. Unless you were willing to spend potentially over $600 for a drawing tablet with a high-resolution screen, you were stuck with a mouse. Creators who work with audio or video were just out of luck, period.

For only $15.99, you can give yourself the rest and reinvigoration that your body and mind crave.
The native timer feature on your iPhone works well enough that you probably haven't even thought about installing a third-party timer. With just a few taps, you can get a countdown for any amount of time up to 24 hours (or one second shy of 24 hours, to be precise). But as fast as it can be to set a timer from the Clock app, there are even faster ways to start the countdown.
In 2018, Niantic unveiled its in-development augmented reality cloud platform for smartphones, the Niantic Real World Platform. A demo showed Pikachu and Eevee cavorting in a courtyard, darting in front of and behind potted plants and people's legs as they walked through the scene. This would be the future of Pokémon GO.
Just as predicted (but perhaps with less fanfare than usual), Apple has made the move of adding a depth sensor to the rear camera of its latest edition of the iPad Pro.
The Pixel 4 isn't for everyone, but it does have its appeal in several specific use cases. Thanks to Instagram, YouTube, and other social media platforms, the fitness industry and smartphone world are now intertwined like never before, and it appears Google's aware of this.
There's a direct correlation between the proliferation of augmented reality apps and the demand for 3D content, and PTC just quantified that in dollars.
If you're still working your way through the hundreds of features and changes that iOS 13 brings to your iPhone, you might be a bit surprised to learn that your device is now out of date. While Apple only dropped the big update for iPhones on Thursday, Sept. 19, the company has already released its successor. All iOS 13-compatible iPhones can now update to iOS 13.1, out today, Tuesday, Sept. 24.
Unlike many other OEMs, Samsung has two prolific phone series they release each year, the Galaxy S series and Galaxy Note series. At first, the latter was the bleeding edge of technology, but in recent years, the line has been blurred. So what do you get with the Note 10+ over the S10+ besides a stylus? Let us compare.
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.
We've all been there — using Google Maps for navigation and waiting for the app to find our location. As we drive around, we keep hoping it will get a lock in time to make the next turn. Well in the US, we finally have a solution to this problem, and it's the OnePlus 7 Pro.
This week, Next Reality published profiles on the leaders in augmented reality hardware industry, with Magic Leap CEO Rony Abovitz topping the list. So, it should be no surprise that two app makers want to align themselves with Magic Leap's flagship product.
Two companies armed with web-based augmented reality tools, Vertebrae and Shopify, are ready to help online retailers boost their sales.
One of the most exciting additions to iOS 12 for iPhones is called Shortcuts, a tool integrated with Siri to help you get things done faster. While there are a few recommended shortcuts available to you in Siri's settings in iOS 12, the Shortcuts app brings the functionality of Workflow to Siri so you can build your own custom actions or select from the gallery of available shortcuts.
With the reveal of Magic Leap's developer documentation last week, many questions have been answered—and several new ones have been raised as well. But since the Magic Leap One (ML1) isn't simply called the "Leap One," these are questions that the company probably has no interest (at least for now) in answering. Understandably, Magic Leap wants to keep some of the "magic" under wraps.
When it comes to applying augmented reality to various business functions, as the saying goes, there's more than one way to skin a cat.
HIV infections persist despite treatment that successfully decreases viral blood levels to the point where doctors can't detect the virus. But that doesn't mean the person is cured. The virus hides in the body, not replicating, just waiting for a chance to jump out of the shadows and reemerge.
The technology driving the automated vehicle revolution relies on the car's ability to see and understand the world around it.
It's become a routine for many of us to ring in the New Year with pledges to finally get our budgets and finances under control. Unfortunately, it's also quite difficult to to keep those promises. Some of us will just dive into our resolutions and wing it as we move forward, which usually ends in failure. But even for those of us who plan carefully, obstacles along the way can spell doom for New Year's resolutions.
Hello everyone. I've recently made the annoucement of the Null Byte suite of tools, and we've covered how to download and install it. Now it's time we cover how to submit a tool for inclusion into the suite. It's relatively simple, but we need to get a few ground rules out of the way.
I scream, you scream, we all scream for ice cream. It's a universally loved treat that seems to make everyone who eats it giddy. However, there are two downsides to ice cream, in my opinion.
Your grater and microplane may look like single-purpose tools, but they're actually one of the most diverse appliances in your kitchen. Sure, everyone knows to use a grater on cheese and a microplane on citrus zest, but why stop there? Here are 10 things you may not have thought to grate:
