Citylab reports that Chicago's open-sourced food safety analysis software has made our food inspectors much more effective. Other cities aren't adopting it, though: Chicago started using the prediction tool for daily operations in February 2015, and the transition worked very smoothly, says Raed Mansour, innovation projects lead for the Department of Public Health. That’s because the department was careful to incorporate the algorithm in a way that minimally altered the existing business practices....

It's a slow, agonizing death: A report from the real estate service firm NGKF released late last year provides new numbers on an ongoing phenomenon: the slow, agonizing death of the American office park. The report looks at five far-flung office tenancy submarkets—Santa Clara, in the San Francisco Bay Area; Denver; the O’Hare region in Chicago; Reston/Herndon outside of Washington, D.C.; and Parsippany, New Jersey—and finds a general aura of decline. Between 14 and 22 percent of the suburban office...

The New York Times Magazine has an in-depth analysis of the daily fantasy sports (DFS) industry. I'm not that interested in fantasy sports, but this article had me riveted: Here’s how it works: Let’s say you run D.F.S. Site A, and D.F.S Site B has just announced a weekly megacontest in which first place will take home $1 million. Now you have to find a way to host a comparable contest, or all your customers will flee to Site B to chase that seven-figure jackpot. The problem is that you have only 25,000...

Last week, NASA announced data that show this year's El Niño event keeps growing, possibly even surpassing the 1997 event. But they can't yet predict the consequences: While scientists still do not know precisely how the current El Niño will affect the United States, the last large El Niño in 1997-98 was a wild ride for most of the nation. The “Great Ice Storm” of January 1998 crippled northern New England and southeastern Canada, but overall, the northern tier of the United States experienced long...

First, from the scientist behind Deeply Trivial, a Times report that giving people money to answer survey questions makes their answers more accurate: [W]hen you ask people about the economy, the answers are less a statement of objectivity and more like what they’d say if you’d asked which pro football team was the best. That has important implications for democracy. How can people judge whether a party is effective if there is no sense of objective truth? And it could even have implications for the...

Here's the semi-annual Chicago sunrise chart. I'm posting it as a regular post in addition to posting it as a permanent page, to maintain deep-linking archiving. The previous post was here. In just a few hours we'll see the latest sunrise of winter, until the days just before the change back to Standard Time in November. That will bring us something really rare: the latest sunrise in Chicago until November 2027, at 7:29am on November 6th. Thank leap years and orbital eccentricity for that. This...

Here are some numbers illustrating 2015 (cf. 2014 also): I took only 14 trips and flew only 25 segments, visiting 7 states and 4 countries*. Of those, 11 flight segments took off or landed outside the US, which is the highest proportion of international-to-domestic flights in any single year. Those years in which I've flown more international segments were also heavy-travel years in general. For example, in 2001, my heaviest travel year ever, I flew 15 international segments—my record—out of 63...

Sorry, Hawai'i. Your UTC-10 is a full day behind Kiritimati, where it's already coming up on Saturday. But happy new year regardless! And to the few sailors and submariners hanging out in UTC-11, happy new year to you, too, in an hour or so.
