jQuery Video Plugin, Open Source Data View, QR Insanity, and Measuring Citizen Science

  1. jPlayer — jQuery plugin for audio and video in HTML5. Dual-licensed MIT and GPL.
  2. Tesseract (Github) — Square has open sourced (Apache license) their Javascript library for filtering large multidimensional datasets in the browser. Tesseract supports extremely fast (<30ms) interaction with coordinated views, even with datasets containing a million or more records; we built it to power analytics for Square Register, allowing merchants to slice and dice their payment history fluidly.
  3. QR Code MadnessI recently received an MMS (multimedia text message) with a picture to a QR code. First, it’s bad enough advertising agencies still randomly text people ads. Second, what am I supposed to scan that with? My eyes? But check out the photo for maximum silliness.
  4. Galaxy Zoo: Crowdsourcing Citizen Scientists (Guardian) — yes, the headline is a collection of buzzwords but the Galaxy Zoo project remains fantastic. My eye was caught by Working 12 hours a day non-stop for a week, [Kevin] Schawinski had managed the not inconsiderable task of detailing the characteristics of 50,000 galaxies. He needed a pint. [… they built Galaxy Zoo in a day of two …] Within 24 hours of it being announced on Lintott’s website, Galaxy Zoo was receiving 70,000 classifications an hour. They still measure their hit-rate in “Kevin weeks” – a unit of 50,000. “Soon after that we were doing many Kevin weeks per hour,” Schawinski says. (via Roger Dennis)

Moneyball for software engineering

How metrics-driven decisions can build better software teams.

Don't dismiss "Moneyball" just because it began in the sports world. Many of the system's metrics-based techniques can also apply to software teams.

Poor Economics, Shrinking Web, Orphans Put to Work, Realtime Log Monitoring

  1. Poor Economics — this is possibly the best thing I will read all year, an insightful (and research-backed) book digging into the economics of poverty. Read the lecture slides online, they’ll give you a very clear taste of what the book’s about. Love that the website is so very complementary to the book, and 100% aligned with the ambition to convince and spread the word. Kindle-purchasable, too. Sample boggle (one of many): children of children born during the Chinese famine are smaller, and children who were in utero during Ramadan earn less as adults.
  2. The Web Is Shrinking (All Things D) — graph that makes Facebook look massively important and the rest of the web look insignificant. It doesn’t take into account the nature of the interaction (shopping? research? chat?), and depends heavily on the comScore visits metric being a reliable proxy for “use”. I’d expect to see other neutral measures of “use” decreasing (e.g., searches for “school holidays”) if overall web use were decreasing, yet they don’t seem to be. Nonetheless, Facebook has become the new millennium’s AOL: keywords, grandparents, and a zealous devotion to advertising. At least Facebook doesn’t send me #&#^%*ing CDs.
  3. Orphan Works Project (University of Michigan) — library will digitize orphaned works for researchers. Lovely to see someone breaking the paralysis that orphaned works induce. (via BoingBoing)
  4. log.io — node.js system for real-time log monitoring in your browser. (via Vasudev Ram)

Community, Metrics, Sensors, and Unicode

  1. Your Community is Your Best Feature — Gina Trapani’s CodeConf talk: useful, true, and moving. There’s not much in this world that has all three of those attributes.
  2. Metrics Everywhere — another CodeConf talk, this time explaining Yammer’s use of metrics to quantify the actual state of their operations. Nice philosophical guide to the different ways you want to measure things (gauges, counters, meters, histograms, and timers). I agree with the first half, but must say that it will always be an uphill battle to craft a panegyric that will make hearts and minds soar at the mention of “business value”. Such an ugly phrase for such an important idea. (via Bryce Roberts)
  3. On Earthquakes in Tokyo (Bunnie Huang) — Personal earthquake alarms are quite popular in Tokyo. Just as lightning precedes thunder, these alarms give you a few seconds warning to an incoming tremor. The alarm has a distinct sound, and this leads to a kind of pavlovian conditioning. All conversation stops, and everyone just waits in a state of heightened awareness, since the alarm can’t tell you how big it is—it just tells you one is coming. You can see the fight or flight gears turning in everyone’s heads. Some people cry; some people laugh; some people start texting furiously; others just sit and wait. Information won’t provoke the same reaction in everyone: for some it’s impending doom, for others another day at the office. Data is not neutral; it requires interpretation and context.
  4. AccentuateUs — Firefox plugin to Unicodify text (so if you type “cafe”, the software turns it into “café”). The math behind it is explained on the dataists blog. There’s an API and other interfaces, even a vim plugin.

Library Game, Mac Security, Natural Programming, Selecting Metrics

  1. Find The Future — New York Public Library big game, by Jane McGonigal. (via Imran Ali)
  2. Enable Certificate Checking on Mac OS X — how to get your browser to catch attempts to trick you with revoked certificates (more of a worry since security problems at certificate authorities came to light). (via Peter Biddle)
  3. Clever AlgorithmsNature-Inspired Programming Recipes from AI, examples in Ruby. I hadn’t realized there were Artificial Immune Systems. Cool! (via Avi Bryant)
  4. Rethinking Evaluation Metrics in Light of Flickr Commons — conference paper from Museums and the Web. As you move from “we are publishing, you are reading” to a read-write web, you must change your metrics. Rather than import comments and tags directly into the Library’s catalog, we verify the information then use it to expand the records of photos that had little description when acquired by the Library. […] The symbolic 2,500th record, a photo from the Bain collection of Captain Charles Polack, is illustrative of the updates taking place based on community input. The new information in the record of this photo now includes his full name, death date, employer, and the occasion for taking the photo, the 100th Atlantic crossing as ocean liner captain. An additional note added to the record points the Library visitor to the Flickr conversation and more of the story with references to gold shipments during WWI. Qualitative measurements, like level of engagement, are a challenge to gauge and convey. While resources expended are sometimes viewed as a cost, in this case they indicate benefit. If you don’t measure the right thing, you’ll view success as a failure. (via Seb Chan)

The CIO's golden rule of management

With few exceptions, good data is the best way to make great decisions.

We make decisions with data and we measure performance with metrics. It's letting the data and metrics — the evidence — tell the story and then taking some form of action on it.
