An unfair fight? New iPad Air versus 2016 iPad Pro

At the end of March 2016, I purchased one of the newly-introduced 9.7" iPad Pros—a Gray 128GB Wi-Fi only version, to be exact. And until Friday, that was the last full-size iPad I bought for my personal use. (I did buy an iPad mini at the end of 2017, mainly as a test device for new iOS releases.)

However, early last week I decided it was time to upgrade, and after comparing a few models, I chose the iPad Air—Space Gray, 256GB, WiFi only for $649. I didn't really need 256GB of storage, but Apple, of course, only offers the Air in 64GB or 256GB capacities—and as I had about 110GB of stuff on my old iPad, I had to get the 256GB model.

Physically, they two iPads are nearly identical—despite the iPad Air's much larger display area, it's only 0.4" taller and 0.2" wider than the old Pro (they're both .24" thick), and it weighs but 0.6 ounces more.

As I had a Pro before, why didn't I buy a Pro this time, too?

I mainly use my iPad for games, watching movies or listening to music, using the internet, reading books, and sending the occasional email. As an iPad will never be my primary work machine, I didn't feel it necessary to pay the extra $2502An iPad Pro 11" with 256GB and WiFi is $899 for an iPad Pro. (And by choosing the Air, I still don't own an Apple device with Face ID.)

When a light drone is the right drone

Many years ago, I had a big, spendy drone—the DJI Phantom 2 Vision +. This was a monster of a drone, measuring over a foot along the diagonal between the motors, and probably just under a foot in height—this image gives a good sense of the size of the thing:

It was also heavy, weighing in at 2.7 pounds (1.2 kilograms), and it used a 5200mAh battery to provide a claimed 20ish minutes of flight time, though 15 was more typically what I saw. The camera was mounted on a precision gimbal, providing incredibly smooth video—1080p at 30fps (stills were 14mp), which was very good for the time.

While I liked the big drone, for a part-time hobbyist drone user like me, it was also a pain: I needed a big case to transport the Phantom and its spare parts and batteries and charger, it took a while to set up (install propellers, configure controller, make wifi connections, etc.), and I never mastered flying it low-and-slow (perhaps due to the amount of wind its powerful rotors generated). It was also really loud.

Because of the hassle involved with using the drone, I didn't use it as often as I wanted to. So I eventually sold it, and left the world of drones behind for a few years. But lately, I'd been getting the itch again, and after doing some research, bought something much different…

Our family’s robotic vacuum overlords are Deebots

If you're interested in technology (me!), and dislike cleaning (also me!), you've probably investigated robot vacuum cleaners. There are tons of models out there, covering a wide range of costs from under $100 to over $1,500. I'm not here to try to tell you which is the best, or even which particular one to buy, but to point out a time-limited sale on the one we chose to buy.

Back in May, we bought an Ecovacs Deebot N79S (Amazon)1This is a referral link; I make a modest commission if you use it. to clean our downstairs hardwood floors. I bought it mainly because it was on sale for a relatively inexpensive (for a robot vacuum) $150, and it received decent reviews on Amazon and on various review sites such as Wirecutter.

It's not the smartest robot—there's no ability to save a map or mark off "do not enter" areas. But I've found it cleans well, it's quiet, and the app does what it needs to do to make managing the vacuum about as easy as it can be. It's got a stated 110 minute battery life, and ours usually runs for at least 90 minutes, going over mainly hardwood with a couple of area rugs.

I noticed today that it's on sale again on Amazon for about $150—it shows as $170 in the store, but once in the cart, a $17 discount is applied, bringing it down to $153. We've been so happy with the first that I just ordered a second one to use upstairs (with two cats in the house, one cannot have enough vacuums).

I'm not sure how long this special price will last, nor if it's some sort of targeted thing where only certain shoppers get the deal, but if you're in the market for a decent yet not too costly robot vacuum, we've been very happy with ours.



De-distractionate the Touch Bar

Shocking even myself, I'm now the owner of a Touch Bar equipped MacBook Pro—I purchased the entry-level 16" model last weekend. Why? I'll save the detailed explanation for an upcoming look at the machine and its performance, but the main goal was to replace two laptops with one.

But just because I now have a Touch Bar-equipped Mac doesn't mean I suddenly like the Touch Bar. In fact, my feelings about it haven't changed since I wrote about it two years ago:

The Touch Bar, despite its name, is actually an Eye Bar: It forces your eyes off the screen, down to the Touch Bar, back up to the screen, repeat ad infinitum.

After some hours working with my new MBP, this is definitely a problem—and it's a problem even when I'm not using the Touch Bar, which is pretty much all the time: I've found that the changing images and colors on the Touch Bar grab my eye every time I switch apps…

The camera was focused on the Touch Bar, but when I'm looking at the screen, I see all that activity just below the screen, and it's really distracting. Thankfully, there's an easy fix, and one I'd not heard of prior to buying this machine…

Add inelegance to remove heat

At home, our network routing and firewall is handled by an open-source software package called pfSense®; it has a ton of features, and is relatively easy to configure. I built a mini PC (a box roughly 9" per side) for pfSense, and it's been running smoothly for over five years1I'll be writing more about pfSense and my routing PCs in a future post..

While it's not the world's loveliest box…ok, so it may be the world's ugliest box…

…it's been rock solid since day one. However, it's aging and its CPU won't be supported in an upcoming pfSense release, so I decided to replace it. (That way, I'll have a spare if the new one breaks…at least until that unsupported version of pfSense is released.) Here's the new box…

That's a Protectli fanless Firewall Appliance with a quad-core Celeron J3160 CPU, 4GB of RAM, and 32GB of storage. And yes, it's just a bit smaller and more elegant than my old box—the entire thing is roughly the size of my old box's external cooling fan.

2019 iMac vs Late 2014 iMac—Ripping addendum

In Part 1 of my 2014 vs 2019 iMac comparison articles, I provided an overview and a number of comparison benchmark results. In Part 2, I looked at changes in gaming performance between the two machines.

But there was one more thing I wanted to do: Compare Blu-ray ripping speeds. At the time, though, I didn't have any new movies to rip, and I really didn't want to spend the time re-ripping an existing movie. Now, though, I do have a few new movies to rip, as I'm trying to finish our collection of all the films in the first three phases (now called the Infinity Saga) of the Marvel Cinematic Universe.

That meant buying the films I'd liked the least—The Incredible Hulk and the first two Thor movies. With that came the chance to compare the Blu-ray ripping speed of the two iMacs. I use the method described in my article Revisiting ripping Blu-ray discs, which is this:

  1. Use MakeMKV to create an MKV file on the hard drive that contains the video and audio tracks.
  2. Use Don Melton's Video Transcoding tools to create the final movie from the MKV file.

Using The Incredible Hulk, I timed how long it took to create the MKV file and how long it took to create the finished movie. Without further ado, the results (times are in hh:mm:ss format)…

Review: Logitech MX Master 2S mouse

Shortly after I bought my 2014 iMac, my third-party mouse died. So I started using the Magic Mouse that came with the iMac, and added "get new third-party mouse" to my to do list. Although I never found the Magic Mouse all that comfortable, I kept putting off replacing it.

Finally, when I ordered the new iMac—yes, that task sat on my to do list for nearly five years—I decided to go back to an ergonomic button-laden third-party mouse. After some searching and hand-fit tests, I bought a Logitech MX Master 2S ($70 at Amazon) mouse1Note that this is definitely a right-hand-only mouse, and Logitech doesn't appear to offer a left-handed version. Sorry, lefties..

Note: I really dislike reviews that are so short they read more like press releases (and sometimes actually are reprinted press releases). I don't do a ton of reviews here, but when I do, they tend to be long, because I like to use a product first, then review it in depth.

So what follows are many words (and images) about a computer mouse. If you'd like the tl;dr version instead, here it is: I love the MX Master 2S due to its great ergonomics, customizability, and easy multi-computer support. Keep reading for the much longer version.

An unexpected ending to an electrifying car story

If you weren't reading along this week, I spent the last four days—parts one, two, three, and four—talking about my Tesla Model S and how much I love it.

Today's surprise ending is this: I sold the car. What I'd replace it with? This…

Obviously that's another Tesla Model S—a used Model S. It is, in fact, a 2016 Models S 90D—yes, basically the exact car I had, but not really—more on that in a bit. My wife and I call it the unicorn car; read on to understand why, and why I made this trade. (As I was writing this, I learned that others had already used that phrase for this particular vintage of the Model S.)

Important note: We took delivery of our car in April of 2019…in July of 2019, Tesla removed free Supercharging on the used pre-2017 cars they sell. There are no more unicorns, at least through Tesla.

If you want free Supercharging, you'll need to find a pre-2017 car from a private party—staring with the 2017 cars, free Supercharging became non-transferrable.

You can read the rest of the article, but all the references to free Supercharging from Tesla are irrelevant…darn it.

(Credit to Chuck M. for our conversation that made me dig into this.)

An electrifying car story – part four

This is Part Four of a four-part series on our 2016 Tesla Model S. In Part One, I covered why we chose the Model S, the cost of the car, and a bit about Tesla the company. In Part Two, I listed some of the things I love about the car. In Part Three, I listed more of the things I love, plus those things I hate. In today's Part Four, I'll discuss what it's like living with an electric car, cover a somewhat long road trip I took last fall, and offer a few thoughts on the future of auto electrification. Finally, tomorrow's Part Five will provide an unexpected ending (of sorts) to the series.


Living with an electric car

My two-plus years with an electric car have been basically a non-event. There are many reasons for this, including the fact that I work at home, and that we have non-electric vehicles, so the Tesla doesn't have to do everything. (But even if I commuted, with the car's range of 280 miles, I think it'd still be a non-event.)

An electrifying car story—part three

This is Part Three of a five-part series on our Tesla Model S. In Part One, I covered why we chose the Model S, the cost of the car, and a bit about Tesla the company. In Part Two, I listed some of the things I love about the car; today's Part Three has more of the loves, as well as the not-so-loves. Part Four will discuss what it's like living with an electric car, and my thoughts on the future of auto electrification. Finally, Part Five will provide an unexpected ending (of sorts) to the series.


Continuing with the things I love about the car and its infrastructure, and then getting to the not-so-loved things…
