- Abnormal Returns From the Common Stock Investments of Members of the U.S. House of Representatives — We measure abnormal returns for more than 16,000 common stock transactions made by approximately 300 House delegates from 1985 to 2001. Consistent with the study of Senatorial trading activity, we find stocks purchased by Representatives also earn significant positive abnormal returns (albeit considerably smaller returns). A portfolio that mimics the purchases of House Members beats the market by 55 basis points per month (approximately 6% annually). (via Ellen Miller)
- Google News Archive Ends — hypothesizes that old material was “too hard” to make sense of, but that seems unlikely to me. More likely is that it wasn’t useful enough to their machine learning efforts. Newspapers can have their scanned/OCRed content for free now the program is being closed.
- Week Report 310 — BERG’s first (that I’ve seen) video report of the week, and it’s a cracker. No newsreel, just some really clever evocation of the mood of the place and the nature of the projects. I continue to be impressed by the BERG crew’s conscious creation of culture.

Algorithms go awry on Amazon, the future of Hadoop at Yahoo, and the Supreme Court mulls data mining
In this Strata Week: Algorithm pricing on Amazon pushes the price of a biology book to astronomical levels, Yahoo weighs the future of Hadoop, and the Supreme Court hears arguments about a Vermont law restricting the data mining of prescription records.
Banshee Bucks, Log Mining, Visualization Secrets, and Repression Tools
- Canonical’s New Plan for Banshee — Canonical prepare the Linux distribution Ubuntu. They will distribute the popular iTunes-alike Banshee, but instead of the standard Amazon store plugin (which generates much $ in affiliate revenue for the GNOME Foundation) they will have Canonical’s own Amazon store plugin and keep 75% of the revenue (25% going to the GNOME Foundation). They’re legally within their rights, and it underscores for me how the goal of providing freedom from control is incompatible with a goal of making money. Free and open source software gives self-destination with software, and that includes the right to replace your money pump with theirs.
- Oluolu — an open source query log mining tool which works on Hadoop. This tool provides resources to add new features to search engines. Concretely Oluolu supports automatic dictionary creation such as spelling correction, context queries or frequent query n-grams from query log data. The dictionaries are applied to search engines to add features such as ‘did you mean’ or ‘related keyword suggestion’ service in search engines. (via Matt Biddulph on Delicious)

Mining implicit data trails makes CRM more effective
One of the richest sources of data exhaust, email logs contain valuable information. When added to data from a traditional CRM, email analytics can provide a much fuller picture of your company's relationships and activity.
Systems Programming, Peer Review, Web Mining, Facebook Design

- Towards a scientific concept of free will as a biological trait: spontaneous actions and decision-making in invertebrates (Royal Society) — peer-reviewed published paper that was initially reviewed and improved in Google Docs and got comments there, in FriendFeed, and on his blog. The bitter irony: Royal Society charged him €2000 to make it available for free download. (via Fabiana Kubke)

- How Facebook Does Design — podcast (with transcript) with stories about how tweaking design improved the user activity on Facebook. One of the designers thought closing your account should be more like leaving summer camp (you know a place which has all your friends, and you don’t want to leave.) So he created this page above for deactivation which has all your friends waving good-bye to you as you deactivate. Give you that final tug of the heart before you leave. This reduced the deactivation rate by 7%.
Snake Oil, JSON v XML, Pac Man, and the Full Stack
- Data is Snake Oil (Pete Warden) — data is powerful but fickle. A lot of theoretically promising approaches don’t work because there’s so many barriers between spotting a possible relationship and turning it into something useful and actionable. This is the pin of reality which deflates the bubble of inflated expectations. Apologies for the camel’s nose of rhetoric poking under the metaphoric tent.
- Understanding Pac Man Ghost Behaviour — The ghosts’ AI is very simple and short-sighted, which makes the complex behavior of the ghosts even more impressive. Ghosts only ever plan one step into the future as they move about the maze. Whenever a ghost enters a new tile, it looks ahead to the next tile that it will reach, and makes a decision about which direction it will turn when it gets there. Really detailed analysis of just one component of this very successful game. (via Hacker News)
- The Full Stack (Facebook) — we like to think that programming is easy. Programming is easy, but it is difficult to solve problems elegantly with programming. I like to think that a CS education teaches you this kind of “full stack” approach to looking at systems, but I suspect it’s a side-effect and not a deliberate output. This is the core skill of great devops: to know what’s happening up and down the stack so you’re not solving a problem at level 5 that causes problems at level 3.
Crap Phones, HTML Editors, Digital Rights Minimization, and Data Munging
- The Most Popular Phone in the World (Gizmodo) — I have a mate who does prototyping R&D type stuff at a telco and this is his phone. “Why’d you carry a crap phone like that?” “Because this is the most popular phone with our customers.” The Gizmodo article talks about an upcoming Nokia that looks very promising: full keyboard, camera, et al. for under $100.

- How Do We Solve a Problem Like Geographic Restrictions — if you’re building a new business in the US around ebooks, digital music, or digital video, then be aware that your international uptake will be absolutely buggerized by rights issues. YouTube is the only US media site that doesn’t suck for overseas users: don’t rave to us about Hulu, it’s inaccessible to the rest of the world. (via Liza Daly on Twitter)

- Mac App Store Guidelines — Apple announce an app store for the Macintosh, similar to its app store for iPhones and iPads. “Mac App” no longer means generic “program”, it has a new and specific meaning, a program that must be installed through the App store and which has limited functionality (only one can run at a time, it’s full-screen, etc.). The list of guidelines for what kinds of programs you can’t sell through the App Store is interesting. Many have good reasons to be, but It creates a store inside itself for selling or distributing other software (i.e., an audio plug-in store in an audio app) is pure greed. Some are afeared that the next step is to make the App store the only way to install apps on a Mac, a move that would drive me away. It would be a sad day for Mac-lovers if Microsoft were to be the more open solution than Apple. cf the Owner’s Manifesto.
