I forgot that I picked up my FitBit a year ago this week. So how am I doing since 24 October 2014?
- 4.76 million steps (13,000 per day)
- 4,081 km (11 km per day)
- 4,557 floors (12 per day)
By FitBit's reckoning, that puts me somewhere around the 90th percentile of FitBit users worldwide. It also means I've walked the entire length of Japan and climbed enough stairs to reach the normal cruising altitude of a commercial jet.
And Parker and I are about to get more steps in just a few minutes.
This post has a personal and a technical significance.
Personally: exactly 10,000 days ago, I was graduated from high school, at about this time of day.
Technically: The new blog engine let me pre-post this several days ahead, something the old blog engine thought it could do but never quite succeeded.
That is all.
Now that Chicago's bike share has hundreds of stations, its efficiencies are becoming clearer:
But what about convenience? Recently Divvy held its second annual data visualization challenge, and one of the winners, by Shaun Jacobsen at Transitized, compares the speed of Divvy with the speed of the CTA. And Divvy wins by a nose.
Jacobsen’s “Who’s Faster” project starts with a look at the 1,000 top “station pairs"—i.e. the places that people most often go from point A to point B using Divvy. Then, those are compared to the same route on the CTA at noon on a Monday.
And a couple patterns emerge. One is that the bulk of station-to-station trips are faster, centering on five minutes’ savings. It might not sound like much, but it adds up; Jacobsen calculates 32,023 hours saved over 571,634 trips. The other is that the most heavily-used station pairs tend to save more time than less frequently-used ones, as if people are starting to figure out how it works.
After almost two years, the trail opens June 6th:
Built on a long-defunct railroad line, the trail runs through Bucktown, Wicker Park, Logan Square and Humboldt Park. Work on the $95 million project began in fall 2013. Take a look at the path under construction.
When the trail opens, four of the access points will be through ground-level parks: Walsh Park, 1722 N. Ashland Ave.; Churchill Park, 1825 N. Damen Ave.; Julia de Burgos Park, 1805 N. Albany Ave.; and Park 567, 1805 N. Milwaukee Ave.
When completed, the 606 it will include six parks, an event plaza, an observatory, art installations, educational programming and other amenities, Emanuel said in a news release.
Parker and I will take a hike on it as soon as practical—possibly June 7th.
The final score from my FitBit challenge over the weekend was: friend, 33,800; me, 37,800. Yesterday I gave Parker 3 hours of walks and also walked home from dinner instead of taking public transit or a Divvy, which got me almost to 23,800 steps (and 17.7 km) for the day.
There was a cost. My feet hurt, Parker was lethargic this morning, and I ate too much. And this week it's not likely I'll get 10,000 steps in every day this week because I've got an all-day meeting Wednesday. Which is probably a good thing, according to my feet and my dog.
Electric bikes that move between bike share stations may solve the bike-rebalancing problem:
The goal of this research is to derive algorithms directing the vans and trucks that bike-share operators use to shuffle bikes from station to station within a city. Trouble is, rebalancing is a moving target with several layers of complexity. You not only need to predict how many bikes a station will need at a certain time, but you need to minimize the (costly and time-consuming) movement of these vans and trucks—and you need to do it all while the system is in use.
Algorithms aren't the only option. Wald reports that at least one researcher is modeling a system in which driverless bike-share trucks could rebalance stations automatically. Of course, an easier way would be for bike-share systems to use electric bikes that shuffled themselves. But the thought of a bike traveling without a rider does bring up the problem of, you know, balance.
Meanwhile, Chicago's Divvy system will add another 100 or more stations next year, all the way up into Rogers Park and down to the far South Side.
Crain's reported this morning that the Divvy bike-share program lost $150k on $2.2 million in revenue last year:
Though the operating loss is not unexpected, and the amount is relatively small, it comes at a time when Mr. Emanuel is under intense pressure to cut costs and avoid tax increases. The bicycle-sharing program has not yet reached many neighborhoods, reinforcing a view that Divvy is merely a toy for yuppies and tourists.
With the program expected to ramp up this year, achieving profitability is crucial to its long-term success. The administration expects Divvy to at least break even this year.
The program has proved popular with out-of-towners, but it must win over more price-sensitive customers, such as city residents.
So, the program seems on track, and the $12.5-million infusion from Blue Cross certainly hasn't hurt. I'm encouraged.
I'm David Braverman, this is my blog, and Parker is my 7½-year-old mutt. I last updated this About... page in September 2011, more than 1,300 posts back, so it's time for a refresh.
The Daily Parker is about:
- Parker, my dog, whom I adopted on 1 September 2006.
- Politics. I'm a moderate-lefty by international standards, which makes me a radical left-winger in today's United States.
- The weather. I've operated a weather website for more than 13 years. That site deals with raw data and objective observations. Many weather posts also touch politics, given the political implications of addressing climate change, though happily we no longer have to do so under a president beholden to the oil industry.
- Chicago (the greatest city in North America), and sometimes London, San Francisco, and the rest of the world.
- Photography. I took tens of thousands of photos as a kid, then drifted away from making art until early 2011 when I finally got the first digital camera I've ever had whose photos were as good as film. That got me reading more, practicing more, and throwing more photos on the blog. In my initial burst of enthusiasm I posted a photo every day. I've pulled back from that a bit—it takes about 30 minutes to prep and post one of those puppies—but I'm still shooting and still learning.
I also write a lot of software, and will occasionally post about technology as well. I work for 10th Magnitude, a startup software consultancy in Chicago, I've got more than 20 years experience writing the stuff, and I continue to own a micro-sized software company. (I have an online resume, if you're curious.) I see a lot of code, and since I often get called in to projects in crisis, I see a lot of bad code, some of which may appear here.
I strive to write about these and other things with fluency and concision. "Fast, good, cheap: pick two" applies to writing as much as to any other creative process (cf: software). I hope to find an appropriate balance between the three, as streams of consciousness and literacy have always struggled against each other since the first blog twenty years ago.
If you like what you see here, you'll probably also like Andrew Sullivan, James Fallows, Josh Marshall, and Bruce Schneier. Even if you don't like my politics, you probably agree that everyone ought to read Strunk and White, and you probably have an opinion about the Oxford comma—punctuation de rigeur in my opinion.
Thanks for reading, and I hope you continue to enjoy The Daily Parker.
My walk to the bus this morning, through a park path that I forgot they don't shovel:
I could have taken a Divvy bike but...well, for some reason they're closed today:
The good news is, it's stopped snowing for now. The bad news is, we're heading down to -17°C tonight.
I texted some friends in Atlanta and Houston with the top photo. For some reason they don't want to visit Chicago just now.
Apparently, Chicago's Divvy is really popular with tourists—and tourists have trouble returning the bikes on time:
Chicago's Divvy bicycle-sharing program took in up to $2.5 million during its first five months, a figure driven by tourists and others who bought daily passes and racked up the majority of overtime fees, according to a trove of preliminary customer data provided by city transportation officials.
As much as $703,500 came from late charges, which kick in when bicycles aren't returned within 30 minutes. Just a sliver of that money was generated from Divvy's clock-conscious annual members, who checked out bikes for short trips instead of hopping into taxis or riding public transit, city officials concluded.
It's not clear whether the Divvy public-private partnership, supported by $25 million in federal funding and $6.25 million in local matches, is turning a profit.
The article goes on to suggest that tourists have trouble understanding the point of the 30-minute time limit. It's not to prevent you from riding Divvy bikes; it's to keep Divvy bikes moving. If the program didn't have a 30-minute window, people would ride to their destinations, park the bikes, and ride back, possibly tying up a bike all day.
So the problem seems to be user education.
Still, I'm glad the program is making revenue. I really hope it's profitable.
