NON-FUNGIBLE IS ALL THE RAGE

Did you hear about the New York Times article, still online, that sold for $560,000? How about the digital cat in a pop tart? It sold for $590,000. Or the 5,000 online images that sold for $69 million? They’re part of the brave new world of “Non-Fungible Tokens.”  “Non-fungible” means “can’t be copied, unique,” much like the items on Antiques Roadshow. In the digital world, Non-Fungible Tokens (NFTs) are sold in online auctions. If you buy a token, you own a link to a unique piece of digital art, music, video clip or what-have-you. Recently, a video clip of  LeBron James’s basketball dunk was tokenized. The buyer paid over $200,000. Before NFTs, digital files weren’t considered unique because they’re so […]

NEW PORTABLE POWER BANK SAVES THE DAY

On a recent plane trip, I watched in dismay as the power drained from my phone. By the time I got from Chicago to New Hampshire with a stop in Philly, it was circling the drain.  A portable power bank is the answer. Here are two questions: How fast can it restore a phone to full charge? Does it lose power when not in use? In the past, on the rare occasions when I’ve thought to bring a power bank with me, it turned out it wasn’t charged and I didn’t have time to mess with it. Power banks with lithium ion batteries should retain their power months after they’ve been charged. But some products that claim to have lithium […]

WHICH AMAZON REVIEWS ARE FAKE?

You can buy a thousand positive reviews on Amazon for $10,900. That’s less than $11 each. So how do you know which reviews to trust? I looked at an ArsTechnica article, “Posing as an Amazon Seller” to find out. One commenter said he rented a dreadful movie that had 4.5 out of five stars and over 10,000 positive reviews. Now he avoids anything with reviews in the thousands. A reader told me he only looks at the most recent ones. A third commenter observed that some reviewers get $20 per review. He says he’s in the wrong business. A United Kingdom consumer group found 702,000 product reviewers from just five companies. All were in the review-manipulation biz. Besides offering positive […]

SMARTER EYES

My mom used to swear by eye exercises. She said they would correct nearsightedness. Science may be proving her right. Kubota smart glasses can fix your eyesight, if you wear them 60 to 90 minutes a day, according to a report in ZME Science. They work by shortening the distance from the cornea to the retina using augmented reality and virtual reality. Fortunately, you don’t have to wear them for hours at a stretch. They’re a bit odd-looking. At a distance, the lenses look like windshields after rocks have shot through them. The smart glasses were developed by Kubota Pharmaceutical Holdings of Japan. In Japan, 95 percent of those under age 20 are myopic. In South Korea, it’s 96 percent, […]

WHAT’S APP WITH THAT?

A couple of months ago I started using the free app “WhatsApp” for sharing pictures and making free phone calls. Now millions are angry with the app, turning instead  to “Signal” or “Telegram.” Switching from WhatsApp to Telegram is like switching from sugar to corn syrup. Telegram has had problems with foreign terrorists, neo-Nazis and white supremacists. It was recently used for hacking into Facebook accounts. And it’s not that private. Telegram allows businesses to collect data on you so they can send you ads. But what’s so bad about WhatsApp, anyway?  I don’t care that it’s owned by Facebook. Starting in May, businesses will be able to collect data on you so they can send you messages. But that’s […]

GOLD VERSUS BITCOIN

Bitcoin, the digital currency, has been going up like crazy. But is it a better store of value than gold? Last year, Bitcoin went from a little over $7,000 to over $26,000 per digital coin. On January 8, a single coin hit $40,675.80! I’ve had some experience with cryptocurrency. In 2017, I bought part of a Bitcoin at Coinbase.com, when it was valued at around $4,000. I bought a bit more when it rose to $15,000. What can I say, I’m a gambler. Unfortunately, I sold it after it crashed below $4000. Disaster! I admire those who “HODL” a Bitcoin acronym standing for “Hold On For Dear Life.” According to a deVere Group survey of their own clients, 67 percent […]

SANITIZING THE PHONE

For Christmas, my brother-in-law got me a phone sanitizer that looks like a flower vase. If I drop my phone into the $80 “Oblio,” I get a germ-free phone after 20 minutes. Or so the company claims. But the directions asked me to flip my phone to clean the other side when the 20 minutes were up. When I flipped it, the purple ultraviolet light, the one that cleans, did not come on. Tech support was no help. They asked me to send a video of the problem. That’s when I discovered that the UV light doesn’t come on at all now, even at the start. A good alternative is the $80 “PhoneSoap” sanitizing box. It sanitizes both sides of […]

GETTING ZOOM HIGHLIGHTS

I’ve often wished I could capture the highlights of a Zoom meeting in a short video clip. Now, with a free app from Grain.co, I can. I started with a two-hour meeting recorded six months ago, which appeared in the Grain app automatically. I just had to click “import.” Then, by scrolling through the transcript underneath the video, I quickly got to the part where my nephew says “happy birthday” to my sister. When I highlighted the text and clicked the “share” button, Grain created a 17-second video clip, complete with transcript, ready to share in an email, on Facebook or wherever. On Thanksgiving, I had a Zoom meeting with my brother, nephews and niece-in-law. I figured they wouldn’t want […]

PORTABLE POWER STATION KEEPS DEVICES GOING

If you find yourself camping in the woods with all of your gadgets, consider a portable generator to keep everything charged. I’ve been testing the “PS500N,” $490 from iForway.com. It could power a 60-inch TV for three hours if you want to lug it along to the woods. The PS500N is about the size of a breadbox, weighs 13 pounds, and uses no gasoline. The user manual calls it a “Portable Solar Generator,” but there’s nothing solar about it, unless you add a portable solar panel, which iForway sells for $190. (A solar panel could be useful for topping up.) With just the generator, you could charge a phone 45 times, a camera 75 times, a tablet 12 times, and […]

LOOK MA, NO GLASSES PRESCRIPTION

I asked a friend to be a guinea pig for the “EyeQue,” a $60 gadget that tests your eyesight and gives you a prescription.  Results were great for him, not so for me — but that wasn’t the machine’s fault. Besides giving you a prescription, EyeQue will send you a pair of John Lennon-style glasses for an additional $19. They call them “try-ons.” They work well and look fine, but you’ll probably want another pair. For instance, the bridge width and earpiece length may be slightly off, since EyeQue doesn’t ask for these measurements, which are typically found on your old pair of glasses. My friend ordered new frames from GlassesUSA, which is not affiliated with EyeQue. He now sees […]
