Divvy Bikes and Logistics

Divvy bikes came to Chicago this year towards the end of the summer and they seem to be a big hit. We see people riding Divvy bikes all the time and they have a distinctive “flash” light on the front (like a strobe) that is visible from far away, even from our condominium high up over River North.

I often walk near the train station and I noticed the Divvy van loading up bikes when the obvious hit me; Divvy bikes came from all over the city and ended up near the train station. These vans were redistributing the bikes back to other stations so that the next days’ rush hour could repeat the process.

The stations seem to have a solar powered panel; they should connect each of the bikes to a sensor and then broadcast to a central station so that they can map out bike usage in regular intervals and use this information to improve their bike distribution algorithm. I assume that they can also make some stations larger than others; this way you could collect many bikes downtown and then redistribute them to stations that they came from (presumably on the north side) during the day. Here is an article I found about the Divvy “Rebalancers“.

Perhaps some day they could alter pricing in some sort of “congestion” model to charge people more who drop bikes off at popular stations and charge people less to ride those same bikes in the opposite direction to less popular stations. This could supplement the “rebalancers” with market forces. Grist for an MBA case study perhaps?

Happy Holidays

Happy Holidays from Chicago! And I want to give a special thanks for the writers of America 3.0, who are taking time out from their busy lives and mercantilistic duties in order to try to bring a positive set of recommendations for the future.

Christmas Day

Merry Christmas to all. My youngest daughter drove 8 hours from Tucson and my oldest son 9 hours from San Francisco yesterday to be with the family Christmas Eve. We were all at my younger son’s house for their annual party but he had to work at the fire house. Today we will assemble at various houses and one restaurant for dinner. All are healthy and happy.

My best to all.

I have research subjects for this morning. My daughter-in-law wanted to know the value of the tetra drachma I had given my middle daughter as a birthday gift this year. I bought it from a workman at Ephesus a few years ago. It is the most perfect Attic Owl I’ve ever seen. I had it mounted in a necklace. This morning I’ve been researching the subject. What would a tetra drachma buy in 500 BC ?

My son-in-law and I discussed the question of extra-terrestrial life last evening. I’m doing some research on Archea and extremophiles today. Lots to do on Christmas Day before dinner time.

… natus ex Maria virgine …

And in the same region there were shepherds out in the field, keeping watch over their flock by night. And an angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were filled with great fear. And the angel said to them, “Fear not, for behold, I bring you good news of great joy that will be for all the people. For unto you is born this day in the city of David a Savior, who is Christ the Lord. And this will be a sign for you: you will find a baby wrapped in swaddling cloths and lying in a manger.”

Luke, 2:8-12.

Merry Christmas to all of our Chicago Boyz contributors, readers, friends and families.

Father Christmas and the Provost

(This is actually an episode from one of my books, redone as a free-standing short story for an anthology of Christmas stories by other indy authors, which never went anywhere, so is posted here as my own Christmas contribution.)

It was Vati’s idea to have a splendid Christmas Eve and he broached it to his family in November. Christian Friedrich Steinmetz to everyone else but always Vati to his family; once the clockmaker of Ulm in Bavaria, Vati had come to Texas with the Verein nearly twenty years before with his sons and his three daughters.
“For the children, of course,” he said, polishing his glasses and looking most particularly like an earnest and kindly gnome, “This year past has been so dreadful, such tragedies all around – but it is within our capabilities to give them a single good memory of 1862! I shall arrange for Father Christmas to make a visit, and we shall have as fine a feast as we ever did, back in Germany. Can we not do this, my dears?”
“How splendid, Vati! Oh, we shall, we shall!” his youngest daughter Rosalie kissed her father’s cheek with her usual degree of happy exuberance, “With the house full of children – even the babies will have a wonderful memory, I am sure!” Her older sisters, Magda and Liesel exchanged fond but exasperated glances; dear, vague well-meaning Vati! All of Gillespie County was under martial law and Duff’s Partisan Rangers had despoiled so many farmsteads, claiming they were owned by Union sympathizers. Men of the town had been arrested for refusing to take the loyalty oath, refusing service in the Confederate Army, for even speaking against secession or refusing to accept Confederate money. How could a happy Christmas make up for all that?
