- Fly Eyes Makes Better Robot Vision — to make smaller flying robots, researchers would like to find a simpler way of processing motion. Inspiration has come from the lowly fly, which uses just a relative handful of neurons to maneuver with extraordinary dexterity. And for more than a decade, O’Carroll and other researchers researchers have painstakingly studied the optical flight circuits of flies, measuring their cell-by-cell activity and turning evolution’s solutions into a set of computational principles. […] Intriguingly, the algorithm doesn’t work nearly as well if any one operation is omitted. The sum is greater than the whole, and O’Carroll and Brinkworth don’t know why. Because the parameters are in constant feedback-driven flux, it produces a cascade of non-linear equations that are difficult to untangle in retrospect, and almost impossible to predict.

- Meat Band Aids and Mass Production of Living Tissue — Apligraf is a matrix of cow collagen, human fibroblasts and keratinocyte stem cells (from discarded circumcisions), that, when applied to chronic wounds (particularly nasty problems like diabetic sores), can seed healing and regeneration. This Gizmodo Q&A is informative.

Barcode Scanning, Downloadable Community Book, Gov Hack Day, Android Kludges
- Red Laser — “impossibly accurate barcode scanning”. Uses Google Product Search to identify products that you scan using the camera on the phone. I remember Rael and I talking to Jeff Bezos about this years ago, before camphones had the resolution to decode barcodes. The future is here and it’s $1.99 on the App Store … (via Ed Corkery on Twitter)

At Velocity this year Microsoft, Google and Shopzilla each presented data on how web performance directly impacts revenue. Their data showed that slow sites get fewer search queries per user, less revenue per visitor, fewer clicks, fewer searches, and lower search engine rankings. They found that in some cases even after site performance was improved users continued to interact as if it was slow. Bad experiences have a lasting influence on customer behavior.
Bad Writing, Tech Immigration, Long Tail Fail?, and The Real McKoi
- Dan Brown’s 20 Worst Sentences — awful awful writing, and glorious glorious mockery of it.

It’s not clear what Brown thinks ‘precarious’ means here.

- Rethinking The Long Tail: How to Define ‘Hits’ and ‘Niches’ — the argument comes down to absolute vs relative measurements of popularity. Anderson says that relative hides too much, because percentages are meaningless in a world of infinite inventory. Researchers respond that hits and niches are defined in absolute numbers (top 10, bottom 100). The real takeaway is that infinite inventory requires excellent discovery tools drawing upon collective intelligence systems (hence the Netflix recommendation contest). (via timoreilly on Twitter)
- The Mckoi Database — MckoiDDB is a database system used by software developers to create applications that store data over a cluster of machines in a network. It is designed to be used in online environments where there are very large sets of both small and big data items that need to be stored, accessed and indexed efficiently in a network cluster. The focus of the MckoiDDB architecture is to support low latency query performance, provide strong data consistency through snapshot transaction isolation, and provide tools to manage logical data models that may change dramatically in physical network environments that may experience similar dramatic change.

The market has been on a steady decline since mid-2008 and has continued downward right through the first half of 2009. And there are very few signs that the book-buying slump is going to turn around anytime soon. Overall, the market saw 595,821 fewer units sold in the first half of 2009 than were sold in the same period of 2008. Although we do not have data to show the trends between 2000 and 2003, the market performance this year is the worst we’ve seen since the fall of of 2001. You’ll notice in the chart below that the seasonal patterns have remained consistent, but sales are at a much lower volume than any previous year.

- What The Government Doesn’t Understand About The Internet And What To Do About It — Tom Steinberg from MySociety lays it out. As true for US, NZ, and every other country as it is for the UK (for which it was written). Accept that any state institution that says “we control all the information about X” is going to look increasingly strange and frustrating to a public that’s used to be able to do whatever they want with information about themselves, or about anything they care about (both private and public). This means accepting that federated identity systems are coming and will probably be more successful than even official ID card systems: ditto citizen-held medical records. It means saying “We understand that letting train companies control who can interface with their ticketing systems means that the UK has awful train ticket websites that don’t work as hard as they should to help citizens buy cheaper tickets more easily. And we will change that, now.” What I like about Tom vs the US’s Gov 2.0 is that Tom puts down philosophy that’s hard to argue with, whereas the US is dangerously close to simply focusing on techniques and that’s subvertible.
