- 10 Things I Learned at CrowdConf 2011 (Crowdflower) — Using his newly released crowdsourcing platform Coffee & Power, Philip [Rosedale] developed his entire company infrastructure and platform through a globally distributed workforce. 288 contributors in 127 locations worked together to get this startup off the ground in a whole new way. The Coffee & Power platform was built in 1,700 commits ranging from $6 quality checks all the way up to full source-code editing. One element of this process was developing the Hudat iPhone app. In less than a month for $2,485, the Coffee & Power community got this mobile app up and running.

- Siddhartha Mukherjee Talks About Cancer (Guardian) — fascinating profile of the author of a “biography of cancer”. Touches on the cognitive biases we’re all prone to, and their damaging effects on patients. Mukherjee cites a study which found that women with breast cancer recalled eating a high-fat diet, whereas women without cancer did not. But the very same study had asked both sets of women about their diets long before any of them developed cancer, and the diet of those who now had breast cancer had been no more fatty than the rest (via Courtney Johnston)

- Microsoft’s Patent Claims Against Android (Groklaw) — behold, citizen, the formidable might of Microsoft’s patents and how they justify a royalty from every Android device equal to that which you would owe if you built a Windows Mobile device: These Microsoft patents can be divided into several basic categories: (1) the ’372 and ’780 patents relate to web browsers; (2) the ’551 and ’233 patents relate to electronic document annotation and highlighting; (3) the ’522 patent relates to resources provided by operating systems; (4) the ’517 and ’352 patents deal with compatibility with file names once employed by old, unused, and outmoded operating systems; (5) the ’536 and ’853 patents relate to simulating mouse inputs using non-mouse devices; and (6) the ’913 patent relates to storing input/output access factors in a shared data structure. A shabby display of patent menacing.

Mixtures of grassroots content generation and unique expertise have existed, and more models will be found. Understanding the points of commonality between the systems will help us develop such models.
Joining the pilgrimage that all institutions are making toward wider data use, FLOSS Manuals is exposing more and more of the writing process.
As a relatively conventional book, the KDE manual was probably a little easier to write (but also probably less fun) than the more high-level approaches taken by some other teams that were trying to demonstrate to potential customers that their projects were worth adopting.
