Test-driven development in the Azure cloud
January 08 2009
In part one of this series I gave an overview of my current project to recreate the elmcity.info calendar aggregator on the Azure platform. In this installment I’ll focus on test-driven development in Azure. Because I’m doing the core aggregator in C#, I’m using the popular NUnit software to automate… read moreiCalendar validation issue #3: Quoted-printable vs HTML
January 06 2009
Next up in my series of iCalendar validation examples: The Frost Free Library feed. It fails in three of the four parsers I tried here, and should have failed in all. It begins like so: BEGIN:VCALENDAR VERSION:2.0 X-WR-CALNAME:Frost Free Library | January 06, 2009 - February 05, 2009 PRODID:-//strange bird labs//Drupal iCal API//EN BEGIN:VEVENT DTSTART;VALUE=DATE-TIME:20090106T203000Z DTEND;VALUE=DATE-TIME:20090106T203000Z SUMMARY;ENCODING=QUOTED-PRINTABLE:Library… read moreiCalendar validation issues #1 and #2: blank lines, PRODID and VERSION

Sam Ruby offers the following advice to those of us who would like to improve the interoperability of iCalendar feeds: Identifying real issues that prevent real feeds from being consumed by real consumers and describing the issue in terms that makes sense to the producer is what most would call… read moreA conversation with Jeff Jonas about connecting dots
January 05 2009
On this week’s Interviews with Innovators show I spoke with Jeff Jonas whose work (and narration of that work on his blog) first captured my interest in 2007. If you follow Jeff you’ll know what he means when he uses phrases like perpetual analytics, non-obvious relationship awareness, semantic reconciliation, sequence… read moreFeed validation revisited: The parallel universe of iCalendar feeds

If you were tuned into the blogosphere back in 2001, you’ll recall lots of chatter about RSS feed validation. RSS came in multiple flavors. Anyone could whip up a feed purporting to be in one or another of those formats, and many of us did. There were all kinds of… read moreDecember 30 2008
For me, one of the 2008’s most important (but least remarked-upon) ideas was spelled out in this post which details how Ward Cunningham implemented Brian Marick’s notion of Visible Workings. The idea, briefly, is that businesses can wear (non-confidential aspects of) their business logic on their sleeves, observable to all.… read moreDatabasing trusted feeds with del.icio.us

In my last entry, I sketched a strategy for maintaining lists of the Eventful and Flickr accounts that I consider trusted sources for the elmcity.info event and photo streams. I didn’t spell out exactly how I plan to maintain those lists, in the Azure rewrite of the service that I’m… read moreLightweight event syndication with trusted feeds

If you check the elmcity.info events page for March 7, 2008 you’ll see that Beau Bristow is performing at Keene State College at 8PM. The Eventful item that has syndicated to the events page doesn’t say anything else. There’s no link to beaubristow.com, though it’s easy enough to find. And… read moreAzure calendar aggregator: Part 1
December 22 2008
For about a week now, I’ve been running a service in the Azure cloud that aggregates calendar events from Eventful.com and from a diverse set of iCalendar feeds. As I mentioned last month, my aim is to recreate and then extend my experimental elmcity.info community information hub, while exploring and… read moreMy rationalization for buying a Wii Balance Board
December 20 2008
This week’s ITConversations show features a cameo appearance by my wife Luann, who came home a couple of weeks ago raving about the Wii Balance Board that she’d been using in physical therapy. I talked with Luann about how her therapists, Anna Domyancic and Darren Gerber, are using the Balance… read moreA recipe for industrial transformation

When Tom Raftery pointed me to this gloomy assessment I had to go back and remind myself of what I found hopeful in Saul Griffith’s extraordinary energy talk at ETech. Saul concedes a 2-degree-C rise in temperature by 2033. The question is what it will take to hold the line.… read moreDecember 09 2008
I should get a life, I know, but I can’t help myself, one of my favorite pastimes is figuring out new ways to wrangle information. One of the reasons that IronPython had me at hello is that, my fondness for the Python programming language notwithstanding, IronPython sits in an interesting… read moreDecember 04 2008
Information technologists often recite David Wheeler’s famous aphorism: Any problem in computer science can be solved with another layer of indirection. Often, though, they omit the corollary: But that usually will create another problem. Those problems used to plague only IT folk. But now we’re all involved. Effective social information… read moreDecember 01 2008
This week’s ITConversations show suffered a tragic glitch that rendered the audio unusable, but I was able to transcribe it as text. My guest is John Leeke, a carpenter who takes care of old buildings and shares his knowledge of the tools and best practices involved in doing that. His… read moreIronPython/Azure status report
November 25 2008
As I mentioned here, I’m exploring the viability of Python as a way of programming the newly-announced Microsoft cloud platform, Azure. Partly that’s because I love Python, but mainly it’s because I believe that the culture surrounding Python and other open source dynamic languages can fruitfully cross-pollinate with the culture… read more
