Living three years in Switzerland without a car did not hinder my bike transport fact it made it more fun since we did many one way trips using the trains and buses instead of a car shuttle. The best part was finishing up the ride with a beer and a nap instead of driving for hours to get home. That option is now gone that we're moving home to Sausalito. Lucky for us these new luxury cars are almost driving themselves...but I'll save that for another story. Today I'm talking about transporting bikes which is an important task for... Continue reading

The TrailNetwork is mostly about exploring the outdoor world to find new places to Run, Bike and Walk, but honestly the way to stay healthy is to get into a routine that gets you out often. Sometimes those routes aren't all that exciting, but the TrailNetwork's automatic analysis can take your "Regular Run" and turn it into a competition over time. The animation shows the TrailNetwork validating that each lap remains on route with the main loop. The result is a confident comparison of lap performances for each lap of this 3 lap run. The comparison goes against all laps... Continue reading

Today we announced that the TrailNetwork is coming soon on our Google+ page by posting some of the cool findings like the Dipsea Trail Race. The TrailNetwork is all about helping people find popular routes to hike, bike and run. It is essentially a search engine that specializes in making sense of personal GPS tracks that have been recorded by users of popular Activity tracking applications and shared publicly. In more technical terms it is a GPS Track Log Aggregator and Search Engine. The target applications being Garmin Connect, Strava, MapMyFitness,EveryTrail and many other applications that have published public data... Continue reading

The TrailNetwork is all about finding routes that many people have repeated in a reliable, consistent manner. As a result we tend to find a lot of race routes since when people are racing they tend to go straight from the start to the finish without any nonsense. So it is no surprise that one of the first big routes to rise to the top was the famous 100 year old point-to-point 7 mile Dipsea Trail Race from Mill Valley to Stinson Beach. I love spirit of the Dipsea race although I've only ever hiked the Trail. For those people... Continue reading

Many people move to Switzerland and live here for years without ever learning German. The xpats make their way to their multi-national company and speak English on the campus and zip home on the easy to use trams. Even with such a schedule one must cook food for the family since eating out is very expensive. It seems all of the groceries sold here in Basel have ingredients and cooking instructions in three languages: German, French and Italian, but rarely anything in English (with the exception of Barney's Best peanut butter). Meine Kinder and ich figured out quickly that our... Continue reading

If you haven't figured it out by now...I really love using technology. Now that we've moved to a country that declares four official languages, none being English, you're probably figuring that I'd be using some technology to help me talk to the locals. You'd be right! I dream of the day when the universal translator I saw on Star Trek would allow me to land on an undiscovered planet and just talk with the local aliens without even appearing to be bad dubbing from a Godzilla movie. Of course I'd also like the sight translator that Captain Kirk apparently possesed... Continue reading

Yesterday Lillie was coming home from a playdate and Carol coming home from work. I watched as Carol approached on the two tram lines that makes up her commute and Lillie stood waiting for the tram. Eventually the two icons started moving together so I text messaged Carol and told her to look for Lillie...who was sitting only one car away and excited to run into each other. It's just such a small town with big resources that allows everyone to work together so well.
Toggle Commented Jan 26, 2013 on A Family with Latitude at GPS Trailblazer
Our recent move to Basel, Switzerland has delivered on some expectations that Carol and I had about Switzerland regarding families: Swiss public transportation is supreme Personal responsibility applies to everyone including children Basel is great for families One of the annoyances of parenting, especially in the United States, is the false belief that children are so fragile that we can't let them do anything or they may get hurt. The result is a bunch of screen additcted fat children sitting on the couch with parents getting angry that the kids are tearing up the house. The children grow up without... Continue reading

I wrote this before Google Now launched. This feature works well on Android phones.
So we just moved to Basel, Switzerland and while running along the Weis river we stumbled upon the most intersting playground. We've never seen any playground like this in the U.S.A. which may explain why the German cars have superior engineering compared to ours. Carol and I first stumbled upon this playground when we were just running along a random street not far from the place we are staying. View it on the map. Here is how it all told by the hard workers themselves. The crane loads the gravel into the hanging buckets. The gravel is transported to the platform for staging. The rocks are picked up by the buckets on the vertical conveyor belt. The rocks are then delivered by conveyor to a sifter that separates the rocks by size. Before processing the empty buckets are placed under three different chutes to receive the small, medium or large rocks. The whole process at work. As we walked away from this playground Lillie said "That was the funnest playground I've ever been to". I would have to agree. Such a well thought out sandbox on a grand scale is conceivable even if unlikely, but this thing was on... Continue reading

I'm a big fan of keeping everything in the cloud and not on paper. My Cloud provider of choice is Google so I stick with Android phones and Google's office applications for both personal and work...specifically Google Calendar for the purpose of this story. GPS is my oxygen so I keep one running all the time on my Android phone and sticking with the Google theme I use Latitude to share my current location with others. I always broadcast my current position on this blog in the upper right using their Badge feature. Yeah, that's right...I know you are thinking... Continue reading

In my previous post I explained how we are now responsible for the well being of three little human beings. Lucky for me my favorite GPS company has entered into the business of tracking precious cargo. Garmin "recently" started to sell the Garmin GTU-10 GPS Locator so I picked one up right away and found a spot in Leo's backpack. Overview The GTU-10 is actually a small piece of hardware that has a few major components: GPS (locator) Mobile Data Connection (communicator) Battery (energy) CPU & Embedded Software (brains) Many people have the misperception that the GPS can actually send...

So it's been a while since I last blogged about anything. To be perfectly honest I've had some life-changing events in the past year which I will leave the details up to the press to explain, but Carol and I are taking care of three elementary school age children now. I suppose I could start writing about the whole experience much like Samantha Bee does on her Eating Over the Sink blog, but as with most things I will add a GPS flavor to the child raising experience. Like every new parent we have been learning about the importance of... Continue reading

I think it would be good for a simpler system. I'm even considering gifting it to my sister who commented on my previous article and I told her to wait because I knew the Revue was coming. Let me know if you have any more questions regarding your system and I might save you some time...or sell you mine:)
A few months ago I wrote an article explaining how we cut the cord on cable TV and stream everything saving us high monthly subscriptions from Comcast cable. The resulting setup was a bit overwhelming for some, but it has been making me happy since I know how it works. Google TV seems like it would be simpler to use than my Macbook Pro as a TV, but I still have too many remote controls required to run everything in the entertainment center. The Logitech Revue has the promise of merging the Macbook Pro and the Remote Control into a... Continue reading

Follow along as we toured Switzerland and Germany by train: Frankfurt, Zurich, Lucerne, Morges at Lake Geneva, Basel, Munich, Berlin and Frankfurt. The maps below show our travels at each of the destinations and the pictures show up on the map in the location we took them. Each map has a story as does each picture, so make sure to read the story underneath the maps. Click markers on the map to preview the picture or on the title of each map and you will be taken to the full page. Enjoy! Lucerne Lucerne has the recipe for a gorgeous Swiss city, cobalt lake ringed by mountains of myth, well-perserved medieval Old Town, covered bridges, sunny plazas, swans in the lake and river, etc. It was a glorious day when we were there. Perfect for touring the lake and the mountains. After lunch and walking around Old Town Lucerne, we took advantage fo the the Golden Roundtrip. The adventure included a nice boat ride across Lake Lucerne, a treacherous ride up the steepest cog railway up Mt. Pilatus to view the Swiss Alps, then a fun ride down on cable cars with more breath-taking views. Click link below to read... Continue reading

Not yet, but I think it may have some smoothing too. Same problem with recording the whole plane ride. On May 31, 2010 2:31 PM, Aaron Roller wrote: Not yet, but I

My recent post recommending the Forerunner 110 for all kinds of activities stills holds strong, but this watch is not for skydivers. The GPS provided elevation is as good as the Forerunner 405 (shown in detail in a previous post) or others, but GARMIN has added a smoothing algorithm that makes the actual elevation path inaccurate for rapid changes experienced during skydiving. Forerunner 110 Elevation vs. Time Notice how smooth the graph looks, but I can guarantee my elevation experience was anything but smooth. Forerunner 405 Elevation vs. Time Notice this elevation is more accurate of reality (minus the small... Continue reading
