Upcoming is downgoing, Elm City is ongoing

May 03 2013

Here’s Andy Baio’s farewell to Upcoming, a service I’ve been involved with for a decade. In a March 2005 blog post I wrote about what I hoped Upcoming would become, in my town and elsewhere, and offered some suggestions to help it along. One was a request for an API… read more

Community calendar workshop next week in Newport News

April 19 2013

My next community calendar workshop will be at the Peninsula Fine Arts Center in Newport News, on Tuesday April 23 at 6PM. It’s for groups and organizations in the Hampton Roads region of Virginia, including Chesapeake, Hampton, Newport News, Norfolk, Portsmouth, Suffolk, Virginia Beach, Williamsburg, and Yorktown. If you’re someone… read more

Walled fields of knowledge

March 19 2013

My dad died of congestive heart failure in 2009. The last weeks of his life weren’t what they could have been had we known enough to get him into hospice care. But we didn’t know, and I’ve felt ashamed about that. If we had it to do over again things… read more

Networks of first-class peers

March 18 2013

Last month ago I wrote a column for Wired.com, Rebooting web comments, that attracted some unsavory feedback. Had the flamers read beyond the second paragraph they might have seen that I wasn’t insisting everyone must use verifiable identities online. But they didn’t. So I wrote another column last week, Own… read more

Indie theaters and open data

March 04 2013

Movie showtimes are easy to find. Just type something like “movies keene nh” into Google or Bing and they pop right up: You might assume that this is open data, available for anyone to use. Not so, as web developers interested in such data periodically discover. For example, from MetaFilter:… read more

Let’s think about what we’re doing right

February 22 2013

In The Better Angels of our Nature: Why Violence Has Declined, Steven Pinker compiles massive amounts of evidence to show that we are becoming a more civilized species. The principal yardstick he uses to measure progress is the steady decline, over millenia, in per-capita rates of homicide. But he also… read more

Flash Fill: Text wrangling for non-programmers

February 18 2013

As Elm City hubs grow, with respect to both raw numbers of events and numbers of categories, unfiltered lists of categories become unwieldy. So I’m noodling on ways to focus initially on a filtered list of “important” categories. The scare quotes indicate that I’m not yet sure how to empower… read more

Homicide rates in context

February 14 2013

In U.N. Maps Show U.S. High in Gun Ownership, Low in Homicides, A.W.R. Hawkins presents the following two maps: From these he concludes: Notice the correlation between high gun ownership and lower homicide rates. … As these maps show, “more guns, less crime” is true internationally as well as domestically.… read more

Scientific storytelling

February 13 2013

It’s said that every social scientist must, at some point, write a sentence that begins: “Man is the only animal that _____.” Some popular completions of the sentence have been: uses tools, uses language, laughs, contemplates death, commits atrocities. In his new book Jonathan Gottschall offers another variation on the… read more

Visualizing structural change

July 28 2011

Think about the records that describe the status of your health, finances, insurance policies, vehicles, and computers. If the systems that manage these records could produce timestamped JSON snapshots when indicators change, it would be much easier to find out what changed, and when. read more

Why Facebook isn't the best home for your public events

June 09 2011

Organizations should strive to own and control their online identities (and associated data) to the extent they can. read more

Uniform APIs for the data web

April 20 2011

What if blogs had come of age in an era when a uniform kind of API was expected? We could then ask questions of blogs in the same way we could ask questions of event services. read more

How will the elmcity service scale? Like the web!

December 22 2010

A blog feed is just a special kind of web page. Anybody can create a blog and publish its feed at some URL. Why not calendars too? read more

The iCalendar chicken-and-egg conundrum

November 12 2010

If you're a school or a business or a band or a club whose website sports an Events tab that doesn't offer a companion iCalendar feed, I hope you'll ask your CMS vendor why not. read more

Heds, deks, and ledes

November 04 2010

Headlines matter. They're always visible to a scan or a search, while other information -- like decks and leads -- are active in far fewer contexts. read more

A lesson in civics, public data, and computational principles

October 26 2010

An efficient model of collective information management relies on principles like pub/sub, indirection and syndication. Translating these principles beyond computational thinkers is the tricky part. To pull it off we need to educate the kids we assume to be digital natives. read more

Developing intuitions about data

October 07 2010

Some kinds of computer files have different properties than others, and thus serve different purposes. Structured representation of data is one such property. If we are trying to put data onto the web, and if we want others to have the use of that data, and if we hope it… read more

The principle of indirection

September 30 2010

Networks of people and data are governed by principles as basic as the commutative law of addition and multiplication. Indirection is one of those principles. read more

Personal data stores and pub/sub networks

September 22 2010

Most people and organizations think of the calendar information they push as text for people to read. Few realize it's also data networks can syndicate. When that mindset changes, a river of data will be unleashed. read more

Twitter kills the password anti-pattern, but at what cost?

September 10 2010

It's good to see Twitter driving a stake into the heart of the password anti-pattern. But the Twitter ecosystem wouldn't exist if it hadn't been possible to sketch ideas, and to explore the unanticipated uses that can emerge from the soup of active ingredients that the web has become. read more

The laws of information chemistry

August 18 2010

Everybody learns that things in the physical world are structured in ways that govern how they can or cannot interact. The right shape will open the door, the wrong one won't. But unless you're on an IT track, you'll likely graduate from college without ever learning this corollary: The right… read more

The power of informal contracts

August 11 2010

In a world full of services like delicious, FriendFeed, and Twitter -- services that can route feeds of data based on user-defined vocabularies -- you don't have to be a programmer to create useful mashups. You just have to understand, and find ways to apply, something Jon Udell calls the… read more

Lessons learned building the elmcity service

August 03 2010

What happens when you mix open source goals, styles, and attitudes with Microsoft tools, languages, and frameworks? You get a cultural mashup. That's what the elmcity project is, and what this series will explore. read more
