Watch the video of this incredible empty net goal by Eric Cole from the Dallas Stars - Boston Bruins game on February 10.

The puck curls left from the boards into the goal in a way that cannot be explained by any rebound off of the sideboards. The only explanation was that the puck was rolling on its edge, resulting in a "Bend it Like Beckham" style swerving trajectory.

Motigo is currently an iOS-only app that was initially released in June 2014 to provide in-race motivation to endurance athletes. This app allows you to record, manage, and play at specific points in your race motivating audio clips from family or friends. I know I'd get a big kick out of hearing my son Jimmy say, "Come on Daddy, you can do it!" at the 2-mile mark of a 5k race.

Motigo is free to download, but currently has in-app purchases associated with each cheer that you want to have a friend record (one cheer is $1.99, five cheers is $7.99).

Motigo has an Indegogo campaign going to fund the development of a subscription mechanism, which I think is a better revenue model for this app than purchasing blocks of cheers, especially if you run multiple races per year.

I love the idea of this app, and can't wait to try it after hockey season ends and I get back to running races again.

As a RunKeeper Elite subscriber who is also working on his first iOS app, I've often thought about apps that would complement RunKeeper or MapMyRun. I think Motigo is clearly that kind of app. More power to them!

Earlier today, Troy Vincent, the Executive Vice President of Football Operations for the National Football League, tweeted a good deal of information about new video and wireless networking technologies that the NFL will test at the ProBowl.

I don't know if this is the first time that the NFL has used Twitter to deliver a message in this fashion, but it seems like they are using Twitter as a vehicle to present information in almost a slide show format.

More information about NFL Football Operations and the technologies they use is available at http://operations.nfl.com/the-game/technology/.

I have to see the documentary Red Army, a documentary about ice hockey in the Soviet Union, which is about to be released by Sony Classics.

According to USA Hockey Magazine, Red Army will open in New York and Los Angeles on January 23, in other cities shortly thereafter. (In Philadelphia and the "New York Area", where I arguably live, the movie will open on February 13.)

Hopefully Russia and its neighbors that used to make up the Soviet Union, don't decide there's something in it they don't like, and decide to hack Sony again.

Leatherman Tread Multitool

This summer, Leatherman will begin selling a bracelet that doubles as a multitool, called the "Leatherman Tread". Every link has multiple uses, if it's disassembled.

Yes, Leatherman apparently has a version of this already in the pipeline that includes a Swiss-made watch component. But Apple-- I need a bracelet like this for the Apple Watch Sport, the aluminum version of the forthcoming Apple Watch, or the Apple Watch itself, which is stainless steel. Seriously, if they made a deal with Leatherman to make this happen, they'd sell a ton of them, and it would be a total win-win.

"Each link on the {Leatherman} Tread is a fully functioning tool that can be removed, used and replaced -- hopefully with minimal fuss. The company even designed it to be fully customizable, so you can include different screwdrivers instead of the box wrenches, or skip the carbide glass breaker in favor of a cutting hook." {via Engadget, photos courtesy of Leatherman}

Drawers in the Storage Box, showing the selection of ear tips

Earlier this fall, I decided to spend some gift money on a pair of good in-ear headphones to use for exercise with my iPhone. I chose Sol Republic Relays in the Black/White color scheme. When you are wearing the Relays, they look very much like the Apple EarPods that come with the iPhone. But these headphones come with four different sets of Ear Tips that provide many semi-custom fit options.

Although the Apple EarPods were a significant improvement over the old iPhone headphones in terms of reliability, they have been badly received because they have unusual teardrop-shaped ear buds that don't fit everyone's ears by any stretch of the imagination.

The Sol Republic Relays, by contrast, have a low-profile design which the manufacturer calls FreeFlex Technology, consisting of a rubber ring surrounding the outside parts of each of the sound drivers.

The sound drivers allow you to mount any one of four different-sized ear tips to them for an almost-custom fit.

I use these Relays when I exercise and for all daily iPhone headphone use, other than podcasting and on-line meetings. I think their sound response is better than the Apple EarPods, and they definitely fit my ears more snugly.

The microphone / volume switch is rubberized and appears to be significantly more water/sweatproof than the EarPods. The only differences between the microphone / volume switch on the Relays and the EarPods other than the rubberization is that the microphone unit is black rather than white, and the Relays' microphone switch is located on the left headphone wire instead of the right one.

The proof of their utility and customizability is that I changed ear tips and gave made them work for Jimmy's appearance as the WXTU Weather Kid last week. Jimmy also got great use out of them, he could hear the radio show hosts well, and his voice came through loud and clear on the air.

The Sol Republic Relays debuted at $79.99, but are regularly available for around $60. They are definitely worth it if you are looking for an upgrade from your Apple EarPods that sound better all day long and work better for listening during workouts. I can't recommend them highly enough.

Hour of Code at the Apple Store

Apple Store Class Leader Explaining Programming to Jimmy

On Thursday, December 11, 2014, I took Jimmy and Peter to the Hour of Code event that took place at the Apple Store at the Willow Grove Park mall in Willow Grove, PA.

This was a fun and informative event that I had initially thought was aimed at kids, but was actually appropriate for non-programmers of all ages.

I had no idea how many accessible programming resources were available at code.org. The coding exercizes that Jimmy and Peter did all involved the characters in Angry Birds, Plants versus Zombies, and Ice Age.

They had a blast and learned a surprising amount about basic programming language constructs like repeat/until and if/then blocks.

I mention these free classes at The Apple Store to friends from time to time, but I can rarely point to documentation of what happened at these events, so people can see how valuable these programs are. I hope this article helps you see the value, and gets you to conside signing up for any event like this in the future.

Kathleen and I have lived in our house in Newtown for almost nine years. When we first moved in, we hadn't had time to buy outdoor holiday decorations, so we used solutions like the Chelsea Light Flurries Projector to blanket the front of our house in virtual snowflakes.

But in the years that followed, like most other people in our community, we invested in Christmas traditional lights. And the ones I've started to purchase recently are long outdoor Christmas light sets that can be strung together in series and connected to a single outdoor power receptacle.

The LED Christmas lights I like best have C6 bulbs, which are the larger bulbs that typically have a raised pattern on the exterior that looks like a checkerboard. I guess this is to look like the bulbs are covered in ice. This pattern is really tough to see from any distance, but the multi-colored strands of C6 bulbs look very nice when hung on the outside of your house.

Most of the sets that are available have bulbs approximately six inches (15 cm) apart on the wire. The 35-foot light sets are typically delivered on a spool, so that they can be put away at the end of the season in a very compact form.

The main reasons to choose LED rather than traditional incandescent bulbs is because LED lights use so much less electricity and do not generate heat. This matters because the bulbs last for years, and multiple 35-foot-long sets can be connected in series to a single 120 volt outdoor power receptacle.

The old incandescent sets were more limited in terms of the number of sets that could be wired together in series and plugged into a single receptacle. This really makes a difference, when you are trying to illuminate a large part of the front of a multi-story house or a long ranch house.

Apple Maps Showing Corrected Location of Wissahickon Skating Club

One of the reasons I started RinkAtlas eight years ago was because a lot of the locations of hockey arenas that were available from navigation systems and mapping websites weren't accurate.

This continues to be a problem today, although the number of serious location errors keeps dropping.

I had a really good experience the other day correcting a location error in Apple Maps. I used Apple Maps to get directions to Wissahickon Skating Club. The Apple Maps app on my iPhone told me that I had "arrived" when I reached the stadium at Chestnut Hill Academy. Anybody who knows the area would know that the stadium is two long blocks northeast of Wissahickon Skating Club.

I hadn't been to Wissahickon Skating Club in about 20 years, so I wasn't sure where the rink was, but I was pretty sure it was nearby. I continued south on West Willow Grove Avenue and found the rink several hundred feet down the street.

This kind of error causes panic for some people, so I submitted a corrected location to Apple Maps, hoping that Apple would see my recommended change and correct their database. They received my update request on December 1 and corrected the pin placement on December 3.

That's a fantastic turn around on a map correction.

If you find an error within Apple Maps, and a named place is not in the correct location, I hope you'll take a moment and submit a correction. I think Apple is processing these requests faster than ever. That will result in better navigation for you and others in the future.
