Get Ready For Planet Mars Close Approach on July 31

On 31 July 2018, the planet Mars will be closer to Earth than it has been in 15 years. Technically, it’s called opposition, and the distance will be 35.7 million miles (57.6 million kilometers.) Look south in the late evening, west of the constellation Sagittarius, to see the dazzling red planet. Even a small telescope will bring out some detail, polar cap, etc. And check with your local planetarium for a special observing event. This NASA doc has the details.

TMO Background Mode Interview with Novelist and Freelance Tech Writer Dan Moren

Dan Moren is a novelist, freelance tech writer and prolific podcaster. He’s written for Tidbits, Fast Company, Popular Science, Yahoo Tech, and Tom’s Guide. He was a senior editor at Macworld for many years and continues to write the excellent Stay Foolish column there every Friday. Today he also writes for Six Colors and hosts severable popular podcasts, including Clockwise and Inconceivable! We chatted about his years before Macworld and how he launched his career by writing about Star Wars for a newspaper (most interesting) and later bumped into Jason Snell at a Macworld Expo. Dan told me the story about the development of his SciFi novel, his favorite Mac and his favorite writing tools for both fiction and tech. Finally, Dan briefed me on the many different podcasts he hosts.

Why We Hunger For the Latest Gizmo. Or iPhone

It’s called The Diderot Effect, and it explains modern consumerism, why you buy things you don’t need. It all started when we were told as kids that we just had to have the awesome decoder ring found in that special cereal box. Today, unless we’ve seen the latest superhero movie or have the latest iPhone, we are somehow less of a person. Our goods define our identity. This linked article provides some perspective on manipulated consumerism.

TMO Background Mode Interview with Amateur Astronomer Mike Weasner

Mike Weasner is a noted amateur astronomer, known for his book on the Meade ETX telescopes, early iPhone astrophotography and work with the International Dark-Sky Association (IDA) in Arizona. Very early in life, Mike fell in love with astronomy, and that led to a B.S. in astrophysics. Via ROTC, Mike later joined the United States Air Force, where he served as a fighter pilot (A-7D), instructor (T-38), and a manager in the Air Force’s Space Shuttle Program Office. After his USAF duty, Mike spent 23 years as a program manager with TRW/Northrop Grumman. We chatted about his Air Force days and some interesting flight experiences. In the second segment, we talked about the construction of his observatory, evolution of his telescopes, astrophotography of asteroids, supernovae patrol and his work with the IDA.

Do Photos of an Event Improve Memory of it? Apparently Not

We take a lot of photos. We upload them. But a study from UC Santa Cruz shows that photographs don’t actually present the truth of the moment: they actually distort it. The effect is called “cognitive offloading.” The linked article explains. “It turns out that photographing gives the photographer significantly less need to encode (i.e. we tend to put more mental stock, if you will, into the photograph that we just took rather than actually encoding the memory ourselves).” Sounds like vacationers need to spend more time gazing and less time photographing.

Go Ahead, Ask Siri if She's Spying on You

Lots have been written, both seriously and in jest, about whether our AIs spy on us. But why not just ask Siri? Will she lie? This light-hearted experiment has been tried, in the provided link, and the nature of the responses is interesting. Some day, Siri will be a lot smarter, but will the answer be just as blunt? Or more helpful? Right now, ::cough:: it seems more like the game of Eliza.

What the iPhone 8 Costs in Other Countries Will Surprise You

An iPhone 8 Plus, in the U.S., with 256 GB of storage goes for US$949. But the that’s the lowest price you’ll pay. Here’s an interesting chart that show how much it’ll cost in many other countries, in equivalent U.S. dollar.s. For example, those in Brazil will pay the equivalent of $1377.  Why? Import taxes.

TMO Background Mode Interview with University Psychologist and Podcaster Dr. Robert Carter

Dr. Robert Carter is a Ph.D. Psychologist at Texas A&M, a long-time Apple enthusiast, and the co-host of the Tech Doctor podcast. He’s very well versed in assistive technologies, having been blind since birth. Robert tells an amazing story about he’s coped with his disability through the years. It started with using a portable typewriter in grade school, discovering the Apple II at age 18 and a speech synthesizer plug-in card, and ultimately using Apple’s extraordinary VoiceOver technology on the Mac—and now iPhone. We chatted about the techniques he uses to read and write, including the use of the Hims BrailleSense Polaris display. We finished with a discussion of his Tech Doctor podcast, and its focus on assistive technologies, and how the evolution of AI and robot technologies look to really help those with disabilities.

How to Become a Good Naked-Eye Stargazer

It’s summer. We’re outdoors at night more than other seasons. Then, when people think about becoming more familiar with the night sky, the various stars and constellations, they often think that a telescope is required. And while it’s true that good views of planets, nebulae and galaxies do require a telescope, there’s a lot one can learn by an organized effort with the naked-eye. In fact, one can argue that a good familiarity with the constellations is an important starting point for all things astronomical. This linked article has great information on exactly how to become a good naked-eye stargazer

How Does Amazon's Fire TV Cube Compare to Apple TV 4K?

The Apple TV 4K has been shipping since September, 2017. Now there’s a new competitor, Amazon’s Fire TV Cube. One might think that a later design might be seriously better than the Apple TV 4K, but as this review demonstrates, the Fire TV Cube is a long way from achieving that. Apple’s mighty little black brick packs some real punch while “the Fire TV Cube is simply last year’s Fire TV combined with an Echo Dot.” This is a good review.

And more. We finished with a discusion of Kirk’s new podcast (with Jeff Carlson) called PhotoActive which is all about photography and the Apple ecosystem.
