- Dan Kaminsky on Bitcoin (Slideshare) — short version: banks are an emergent property as it scales.
- Unethical Ventures (All Things D) — astonishing slam on the new venture fund that Michael Arrington (founder of TechCrunch) will be running while still writing for TechCrunch. This could have been a lot cleaner, of course, by Arrington simply resigning from TechCrunch, becoming a VC and perhaps starting a new blog where his agenda is much clearer, from which he could huff and puff away as he does with much entertaining gusto at real and (mostly) imagined slights. There is certainly precedent for VCs blogging, including Fred Wilson, Brad Feld and Ben Horowitz. And, despite my criticisms about ethics, it is clear that Arrington is a talented writer whose unique voice would be even stronger if it was truly seen as separate from what has become a news organization. But because of his obvious need to be the center of attention — requiring the ermine kingmaker mantle and foisting his patented I’m-here-to-tell-it-like-it-is attitude on us all — that appears to be impossible.
- An iOS Developer Takes on Android — a very easy to follow comparison of the two platforms from a developer who worked on both and who is carefully not partisan. I hadn’t realized before what an advantage OpenGL confers to the iOS devices. It’s not just for 3D games any more (he says, catching up with 2008).

- 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)
Java's wild ride, multicore drives functional, and a look at how the usual programming suspects stacked up in 2010.
This year brought confusion and chaos in the Java space, continued growth for functional languages due to the attack of multicore, and the usual popularity for all of the dynamic languages we know and love.

- Raw Data and the Rise of Little Brother — Turns out, despite the great push for citizen journalism, citizens are not, on average, great at “journalism.” But they are excellent conduits for raw material — those documents, videos, or photos.

One of the defining characteristics of the Rails movement has been its willingness to throw out the rules by which software developers and consultants have typically worked. Those rules typically produce big, overblown projects laden with features that no one ever uses–but which sounded good during the project specification phase. Build the simplest thing that could possibly work, and…
The schedule for RailsConf Europe just went up last week. It's shaping up to be another great conference. A few sessions and tutorials that particularly catch my eye are David Heinemeier Hansson's keynote on Wednesday morning, "Meta-programming Ruby for Fun & Profit" by Neal Ford, "Offline Rails Applications with Google Gears and Adobe AIR" by Till Vollmer, "From Rails Security…
