- The Million Follower Fallacy (PDF) — We found that indegree represents a user’s popularity, but is not related to other important notions of inﬂuence such as engaging audience, i.e., retweets and mentions. Retweets are driven by the content value of a tweet, while mentions are driven by the name value of the user. Such subtle differences lead to dissimilar groups of the top Twitter users; users who have high indegree do not necessarily spawn many retweets or mentions. This ﬁnding suggests that indegree alone reveals very little about the inﬂuence of a user. Research confirms what we all knew, that idiots who chase follower numbers have the influence they deserve.

- Lessons of the Gawker Security Mess (Forbes blog) — nice deconstruction of what happened. In the chat, Gawker’s Hamilton Nolan, after hearing that it is just Gawker users who have been compromised, remarks “oh, well. unimportant”. Gawker’s Richard Lawson wants to know if the breach is limited to “just the peasants?” Don’t trash talk about your users in company channels. The business that forgets it lives and dies on its customers is a business that will eventually be hated by its customers. (via Nahum Wild on Twitter)

From Chromebooks to Arduino to bots: Mike Loukides examines I/O's big themes.
Google I/O 2011 was marked by the Android Accessory Development Kit, the Chromebook vision and lots of robots. Mike Loukides examines the big I/O developments and their possible repercussions.

Electronic Health Records, LilyPad Appeal, Time Management, and Locking Library
- Two Brothers Await Broad Use of Medical E-Records (New York Times) — The Doerrs’ software company is only one of many hoping to cash in on the national mandate for digital medical records. The companies range from giants like General Electric to specialists like Athenahealth that cater to small physician practices. They, like the Doerrs, are betting that the law will help create a turning point for the economics of digital health records, opening the door to rapid adoption by doctors and a thriving business at last. NZ-based Orion Health is expanding at a great rate in the US, doing electronic health records. The tide is beginning to turn away from paper, thank goodness. (via DrChrisPaton on Twitter)
- On Feminism and Microcontrollers (Benjamin Mako Hill) — We found evidence to support the suggestion that LilyPad is disproportionally appealing to women, as compared to Arduino (we estimated that about 9% of Arduino purchasers were female while 35% of LilyPad purchasers were). We found evidence that suggests that a very large proportion of people making high-visibility projects using LilyPad are female as compared to Arduino (65% for LilyPad, versus 2% for Arduino).

- Harness the Power of Being an Idiot — I learn by trying to build something, there’s no other way I can discover the devils-in-the-details. Unfortunately that’s an incredibly inefficient way to gain knowledge. I basically wander around stepping on every rake in the grass, while the A Students memorize someone else’s route and carefully pick their way across the lawn without incident. My only saving graces are that every now and again I discover a better path, and faced with a completely new lawn I have an instinct for where the rakes are.

OSCON's hardware track looks at ways to hack the world around you.
Hacking isn't just for software anymore. A full range of open source hardware hacks — everything from Arduino to parallel programming to small-form computing — will be discussed at OSCON this year. With the current slate of tools, it's never been easier to write code that runs on low-power, small-format devices. And many of these tools are familiar to conventional software developers.
