A spectrometer is a device that splits light into all of the different colors it's composed of that can't be seen with the naked eye. It does this by using a prism to refract or bend the light. Jeffrey Warren over at Public Labs created a tutorial showing how you can make your own video spectrometer and create spectra like the one pictured below. Any guesses as to what the subject is? Believe it or not, that's what whipped cream looks like when viewed through a spectrometer. You can do this w...

The week in AR business news started out with a bang with two bombshell reports that cast a shadow on the AR industry as a whole.
Samsung decided to shake things up this year. In the past, the Galaxy Note series was one large phone. This year, it's two phones: the Galaxy Note 10 and Note 10+. So for the first time in a long time, we can compare the latest standard iPhone, the 11 Pro, to a Galaxy Note device.
For the first time in a while, the battle between Samsung and Apple is really interesting. Unlike previous years where the choice for smaller hands was limited to the Galaxy S series, this year, there's an option for Galaxy Note users. Both sides of the aisle have their best options in years with minimal sacrifices.
Every fall, we can expect a few things: leaves changing colors, cooler temperatures, and Samsung and Apple releasing new phones that fanboys and fangirls will argue about until the following year. This year, Samsung is mixing it up, releasing two phones in the Galaxy Note series. Let's see how the larger phones compare.

Picture this: You finally get that awesome angle, the perfect selfie. You can't wait to post it on your Instagram, except there's one problem — it looks a little flat and the colors just seem off. Maybe it's the lights? Or maybe your new smartphone camera isn't as good as you thought? How are your friends getting those beautiful photos they've been posting on social media?
Now that we've officially seen the HoloLens 2 and Microsoft has shown off the improvements and new superpowers of the augmented reality headset, what about the specs?
While Android does allow apps to use picture-in-picture mode (PiP), only a handful of apps actually support the feature. Most of the apps that do are video apps. The thing is, PiP is useful for more than just watching videos, and the Galaxy Note 9 has included a way to allow any app to offer a similar feature, video or not.
You can never replace the skills and expertise of a professional graphic designer, but Canva comes pretty damn close. It's ridiculously easy to use the drag-and-drop design tool for both professionals and people like me who don't have the need (or knowledge required) to use more advanced graphic design software.
As with most social media platforms, Instagram can be a double-edged sword. On one hand, it's a great way to share and express yourself — but on the other, it can be just as effective at compromising your privacy. Thankfully, there are a few things you can do to protect yourself.
Proxies can be quicker to use than a VPN for specific applications, like web browsers or torrent clients. Both services will hide your true IP address, but a VPN is slowed down because it encrypts all data through a VPN network, while a proxy just acts as a middleman for fetching and returning requests from a server on your behalf. When speed is needed, go proxy.

When I was younger, my best friend's dad would always give us a lollipop on long car rides. I remember three things about those lollipops: they were bright green, tasted delicious, and had a cricket in the center. You know, like a Tootsie Roll Pop... only instead of a Tootsie Roll, a cricket.
As a lover of food, I'm often asked, “If you could only have one food the rest of your life, what would it be?” My answer is always the same: sourdough bread. (Okay, it's not always the same... I usually cheat and say sourdough, fancy cheese, and a good beer.) Admittedly, I'm biased by my own sentimentality. My mother is an expert bread baker, with a major in making sourdough. Her sourdough starter is older than I am, and in all honesty, she's made thousands of loaves, each better than the ne...
While Kobe beef cows get massaged, American dairy cows are taking a real beating. Many people are cutting back on dairy while a growing number of people are discovering that they're lactose intolerant. As the public's disdain of cow's milk grows, milk sales themselves are at a forty-year low.
Kitchen tools are a personal thing. One hard lesson for me to learn is that just because something is popular doesn't mean that it's right for me. Take the slow cooker, for instance.

Certain ingredients that a professional chef might work with in a restaurant-style setting may seem bizarre, dangerous, and even downright scary to a home cook, and for good reason.
Any pizza lover knows that a quality crust is crucial to the whole experience. Good pizza crust should be delicious on its own, for once you get to the edge, it will be without any toppings, sauce, or cheese to disguise a bad character. It should be redolent of fresh, good wheat and taste full-bodied, rather than flat, flabby, or metallic, the way so many big chain and frozen pizza crusts do. The exterior should be crisp, while the interior contains an airy crumb as well as having a tender, s...
