The Tamiflu story: Why we need access to all data from clinical trials | Open Knowledge Foundation Blog
One consequence of our access to this bonanza of regulatory material has been a comparison between the details and broad message of the few published trials and their regulatory much more detailed reports. Apart from discrepancies in reporting harms and some less-than-detailed aspects of study design, we think the mode of action of the drug is not what the manufacturer says and (like FDA) could not find any evidence supporting a number of effects of the drug (including those for which it was stockpiled).

But we do not know for sure because we do not have all the data. The practical result of all this is our refusal to consider published trials (either on their own or as part of reviews) for inclusion in our reviews. There are signs that this distrust of the published word is spreading.

Open Knowledge Foundation Blog » Blog Archive » Art Open Data
There are many potential sources of such data:

Institutions produce collection catalogues, show listings, attendance figures, and organisational information.
Writings by artists, critics, theorists and historians can be processed to provide institutional and market data, to discover factual information, or for affective and aesthetic analysis.
Records of art auction prices have been kept for hundreds of years, with older records freely available.
Biographical information about artists can be extracted from digitised historical sources and from modern sources such as Wikipedia.
Institutional, historical and market data about artworks can build up a picture of its production, reception, and provenance.
Reproductions of artworks can be analysed algorithmically or socially.

What lies ahead: Data - O'Reilly Radar
The old prediction engine was built on business intelligence; analytics and reports that people study. The new prediction engine is reflex. It's autonomic. The new engine is at work when Google is running a real-time auction, figuring out which ad is going to appear and which one is going to give them the most money. The engine is present when someone on Wall Street is building real-time bid/ask algorithms to identify who they're going to sell shares to. These examples are built on predictive analytics that are managed automatically by a machine, not by a person studying a report.

Recovery.gov's Data Transparency Called "Significant Failure" by Watchdog Group
One arguement against raw data came out of the woodwork during the successful push to get the US Senate to offer mashup-friendly XML (extensible markup language) feeds for Senate voting history. "The secretary of the Senate has cited a general standing policy," John Wonderlich, policy director at Sunlight, told Politico's Victoria McGrane, "that they're not supposed to present votes in a comparative format, that senators have the right to present their votes however they want to."

it.gen.nz » Government Information – does it want to be free?
"ownership" of government information is a thorny question unless you have an ideology that makes it easy ("of course it's not owned by the government, it's taxpayer's information -- we paid for it!" vs "of course it's owned by the government, how else can they justify selling it?").

The Nike Experiment: How the Shoe Giant Unleashed the Power of Personal Metrics
And not only can we collect that data, we can analyze it as well, looking for patterns, information that might help us change both the quality and the length of our lives. We can live longer and better by applying, on a personal scale, the same quantitative mindset that powers Google and medical research. Call it Living by Numbers—the ability to gather and analyze data about yourself, setting up a feedback loop that we can use to upgrade our lives, from better health to better habits to better performance.

The Four Hundred--Jeff Jonas Explores the Nature of Data in COMMON Keynote
Aha. Jonas is talking about breaking down the difference between queries, stored queries, and triggers. As you add data, old queries are still waiting for matches, and when matches are found the user's notified even if it's weeks after the original query was entered. Treating database as a jigsaw, not as bucket.

API Value Creation, Not Monetization « Laura Merling’s Blog
On the side of the unexpected but interesting outcomes, Kevin said they have seen a flurry of internally developed business applications. In the past many valuable, internal-facing projects were turned down because the programs had to meet strict top line to bottom line ratios. With the availability to data and services, many teams within the company now have access to things they didn’t in the past, and project costs have been minimized. Throughout the company, consumers of the API have been able to launch successful projects that have created additional revenue and have reduced the overall development costs for new projects.

Performance comparison: key/value stores for language model counts - Brendan O'Connor's Blog
I’m doing word and bigram counts on a corpus of tweets. I want to store and rapidly retrieve them later for language model purposes. So there’s a big table of counts that get incremented many times. The easiest way to get something running is to use an open-source key/value store; but which? There’s recently been some development in this area so I thought it would be good to revisit and evaluate some options.

Why Government should support open and free geospatial data at Gav’s Blog
I don't buy the argument that duplication is bad. I buy the argument that free shitty data isn't as good as free quality data, and the market in NZ is not big enough to make this a business worth protecting, as the repeated near-death of terralink shows. At this point I agree that LINZ ought to have a clearly-defined public-facing mandate for quality data.
