Review: Canmore G-Porter GP-102+ data logger

I recently bought a new big-size camera, bucking the trend of simply using one's iPhone for photographs. That's not to say I don't use my iPhone; it is my main picture taking device. But I wanted a camera that could capture native retina iMac images (at least 5120x2880), and the iPhone can't do that.

After much looking and sweating over the costs, I chose a Nikon D5500, mainly because I already had a Nikon and didn't really want to replace all my lenses. While this is an excellent camera, it was a bit of a budget compromise—it didn't have all the features I really wanted. In particular, it lacks a built-in GPS to geocode all the pictures I take.

As a workaround, I decided to buy a GPS data logger, which is just a small GPS receiver that records GPS coordinates at some interval. Toss the logger in your pocket (make sure it's on and receiving the GPS signals first!), then go take pictures as you normally do. When you return, you can use an app like HoudahGeo to sync the recorded GPS track with the timestamps on each photo. (I'll have more to say about this whole sync process in a future post.) Presto, instant geocoded images!

Tracking uncredited reuse of a popular tweet

The other day, I saw a funny tweet by @gsuberland, and it got me wondering if there were other such bad-tech soldering images out there.

So I went looking, found a few, and sent what I thought was a stupid-simple yet somewhat funny tweet: I stitched together three stock photos showing the actors holding the soldering irons in such a way that they'd be badly burned. I stuck a super quick caption on the image, and off it went:

If you click the image link, you'll see the media has been removed—the copyright owner made a copyright claim. I could probably fight this on the grounds of fair use, education, or satire, but it's not worth the effort, and not really what this post is about. (If you're really curious, here are the three original images.)

The tweet, much to my surprise, took off like wildfire, eventually being liked and retweeted over 2,500 times each, and garnering 250,000+ impressions. I've never sent such a popular tweet. Today, when Twitter removed my composite image, I became curious as to whether it'd been cached anywhere (I didn't save a copy when I made it). So I did a quick Google search on the phrase "all three were taken to the ER" from the original tweet. What I found surprised me, though I suppose it shouldn't have: My tweet was reused dozens of times, and almost never with attribution:

A quick glance through the links finds that most are probably bot-driven sites reposting content from reddit or 9gag. Best as I can tell, the first uncredited reuse—taking my composite image and my text—was in this post to reddit's /funny subreddit.

From there, it was picked up by tons of sites, always without credit or link back to the original source. In fact, of 30 sites I quickly scanned, only one included a linked version of the original tweet: Make wrote about one image in particular (which was the first one I actually saw on Twitter), and included my source link. So thanks, Make, for doing it right.

And to everyone else, glad you enjoyed the humor ... maybe next time you could leave an attribution in place? Hell, who am I kidding, this is the internet.



Retina lollipops

A candy store at the local mall had the most amazing wall of colorful lollipops, and I thought it'd make a wild desktop image for a retina iMac. As I snapped the pic on my iPhone, it took a bit of upscaling to reach 5120x2880, but I think it still looks fine; here's a small-scale version:

I also thought a tunnelized version would be interesting; here's how that came out:

I have these in my normal "rotate random every 15 minutes" cycle, and still get a kick out of the lollipops when they get chosen.



Smart TVs know—and share—what you’re watching

If you own—or plan to own, or plan to give as a gift—a "smart TV" from LG, Samsung, or Vizio, are you aware that these sets share your viewing data with third parties? If not, you should be—even if you're a very 'open' person, the amount of data collected and shared by these sets is quite scary.

For example, Samsung Smart TVs collect the following data:

Information about content that you have watched, purchased, downloaded, or streamed through Samsung applications on your SmartTV or other devices; Information about applications you have accessed through the SmartTV panels; Information about your clicks on the “Like,” “Dislike,” “Watch Now,” and other buttons on your SmartTV; The query terms you enter into SmartTV search features, including when you search for particular video content; and Other SmartTV usage and device information, including, but not limited to, IP address, information stored in cookies and similar technologies, information that identifies your hardware or software configuration, browser information, and the page(s) you request.

Vizio isn't much better; here's what their sets collect:

For VIZIO televisions that have Smart Interactivity enabled, VIZIO will collect data related to publicly available content displayed on your television, such as the identity of your broadcast, cable, or satellite television provider, and the television programs and commercials viewed (including time, date, channel, and whether you view them live or at a later time).

And while I couldn't find LG's privacy policy, it's been caught spying on users.

All three manufacturers ship their sets with data sharing enabled, but it's relatively easy to disable on all three brands. Consumer Reports provides clear instructions for all three companies; unless you really enjoy sharing your viewing habits with unknown third parties, I suggest you disable these onerous data collection tools in your smart TV.



A unique lava lamp time-lapse

We occasionally take our kids to a local place, Big Al's, which is one of those bowling/arcade places that give out tickets as rewards from the arcade games. Being good parents, we too sometimes play the games (you know, to spend time with the kids…yea, that's it). Over the years, we amassed quite a bunch of tickets, but weren't quite sure what to spend them on.

The last time we were there, I was smitten by a lava lamp, similar to this one, but ours has a black base and blue "lava." I don't know why (childhood flashback?), but I decided some of our points cache would go to this mesmerizing but otherwise useless device.

When I got it home, I was surprised at just how long it takes to warm up: It can take nearly an hour before any "lava" starts flowing, and about two hours before it really looks like a traditional lava lamp. During the first hour, though, the melting wax in the lamp makes some really cool abstract bits of art, as seen in the photo at right.

I thought this might make a neat time lapse, so I set out to record it with the iPhone. My first attempt failed, due to the iPhone's auto-adjusting time-lapse feature. Because the lamp takes so long to get going, the gap between frames winds up being quite long. Long enough that when stuff does start happening, the iPhone's time-lapse gaps are too wide to make for an interesting video.

I needed another solution, so I headed to the iOS App Store to see what was available…

Presenting the Apple TV (4th Generation) Password Tester

Earlier, I sent out this hopefully-humorous tweet about the difficulty involved in clicking one's passwords into the new Apple TV password input screen:

Presenting LIMNOPHILE, a 10-character yet easy-to-type Apple TV password.

The chart is just an Excel file, with absolutely no logic—I just colored the squares and counted to fill in the data. But then I got this reply…

So I thought "Why not?," and created an actual spreadsheet that will "click check" any all-letter password you feed it. Here's what it looks like in action:

Just replace RIDICULOUSLYLONGWORD with whatever you like, and see how it'll "click out" on your Apple TV. Obviously, this tool is totally tongue-in-cheek!. Any password built with this tool will be weak as heck. It's just for fun, so don't take it seriously.

Feel free to share and modify, but I'd appreciate a credit back if you do so.

Please note that this is an Excel file, and it relies on conditional formatting, so it may not work in Numbers.



New technology at the auto service center

I took our truck in for service at the local Toyota dealer yesterday. When I drove in, I had to drive over one of these big black things:

I figured it was just a speed bump to get drivers to slow down as they entered the service bays. But when I inquired as to their purpose, the answer was more technologically interesting: It's a tire tread depth scanner. As you drive over, lasers shine on each tire, measuring the remaining depth in each tire's tread. Quoting the immortal Dr. Evil … "lasers!"

Of course, when I parked, the technician went around to each tire, sticking his finger in the tread to check the depth. I said, "What about the fancy machines?" 'Oh, they're not quite ready yet; still have to do it the old fashioned way for another few days.' Oh well. Next time.



Cutting the (headphone) cord

Until very recently, I wasn't a user of Bluetooth stereo heaphones. I don't necessarily have a good answer as to "why not?," other than I recall trying a pair early on, and not being impressed by sound quality and battery life. That was, of course, years ago, but I hold grudges for a long time, it seems.

Recently I thought I'd try cutting the cord again; there are any number of Bluetooth headphones available—including some very expensive models. Needless to say, these are not in my budget as a casual music listener. I was more interested in something in the $100 or less price range, and in an over-the-ear (versus on-the-ear or in-the-ear) model.

While browsing Amazon one day, I stumbled onto these headphones, with possibly the longest product name I've ever seen in Amazon: Sentey Bluetooth Headphones v4.0 with Microphone B-trek H10 Wireless Headphones Headset Foldable with Mic for Running Sport or Travel, 40mm Audiophile Drivers - Also Comes with 3.5mm Cable -Up to 15 Hours Battery - Comes with Free Transport / Protection Carrying Case Ls-4570.

Rolls right off the tongue, doesn't it? I'll just call them Sentey Bluetooth Headphones. Although they list for $100, every time I've looked, they've been listed for sale at $50. And with over 100 very positive reviews—and Amazon's easy return policy—this felt like a safe bet. So I ordered a pair, and have had them for a few days now.

So were they worth $50? Absolutely; keep reading for my review.

Use a mouse and keyboard…and a trackpad

When Apple released its new accessories, I thought it might be time to revisit my input setup. For a few years, I've been using the original Magic Trackpad and the Logitech Wireless Solar Keyboard.

While this setup has worked well for me, I missed the precision of a mouse (so much so that I kept a corded one nearby, and plugged it in when I needed to do such work). So I thought I'd check out Apple's new gear, with the thought of either upgrading to the new Magic Trackpad, or perhaps moving to the new Magic Mouse as my pointing device, and maybe replacing the Logitech with the new Apple keyboard.

Unfortunately, the local Apple Store only had the mouse in stock, not the keyboard or trackpad. Unable to compare the pointing devices, I just bought the mouse. After setting it up, I loved the added precision it provided over the trackpad. But if I was going to be using a mouse regularly, I wanted to narrow the reach from keyboard to mouse, so I pulled out my old Apple wireless keyboard, which is about six inches narrower than the Logitech.

This setup seemed really good, except that I'd be giving up a lot of features by removing the trackpad: I use it with BetterTouchTool and our own Butler (as well as Keymo and Moom) to execute all sorts of gesture-related actions.

How far we’ve come…

Happy 34th birthday, IBM PC!

While I didn't own the original, our family did get one of the follow-on models. But that tweet really got me thinking about just how far we've come in 34 years. And while the original PC did start at $1,565, that price didn't get you much of a usable machine, as noted by oldcomputers.net:

A basic system for home use attaches to an audio tape cassette player and a television set (that means no floppy drives or video monitor) sold for approximately $1,565. PC-DOS, the operating system, was not available on cassette, so this basic system is only capable of running the Microsoft BASIC programming language, which is built-in and included with every PC.

If you really wanted a usable IBM PC, you were looking at a much higher cost (from the same site):

A more typical system for home or school with a memory of 64K bytes, a single diskette drive and its own display, was priced around $3,000. An expanded system for business with color graphics, two diskette drives, and a printer cost about $4,500.

Keep in mind this is 1981 money. Adjusted for inflation, those costs are dramatically different in 2015 dollars:

  • $1,565 (Basic IBM PC) --> $4,109
  • $3,000 (Home IBM PC) --> $7,876
  • $4,500 (Business IBM PC) --> $11,814

Doesn't seem quite so cheap now, does it? But what's really amazing is what you can do with that same amount of money today. I'll use the Home IBM PC as a comparison, so I've got $7,876 to spend. Here's what you can get for that in 2015…
