Drone Conflict, 3D Scanning Booths, Bitcoin Consensus, and Moar Coders
- Beware the Drones (Washington Times) — the temptation to send difficult to detect, unmanned aircraft into foreign airspace with perceived impunity means policymakers will naturally incline towards aggressive use of drones and hyperactive interventionism, leading us to a future that is ultimately plagued by more, not less warfare and conflict. This. Also, what I haven’t seen commented on with the Israeli air force shooting down a (presumably Hezbollah) drone: low cost of drones vs high cost of maintaining an air force to intercept, means this is asymmetric unmanned warfare.
- Scanbooth (github) — a collection of software for running a 3D scanning booth. Greg Borenstein said to me, “we need tools to scan and modify before 3D printing can take off.” (via Jeremy Herrman)
- Bitcoin’s Value is Decentralization (Paul Bohm) — Bitcoin isn’t just a currency but an elegant universal solution to the Byzantine Generals’ Problem, one of the core problems of reaching consensus in Distributed Systems. Until recently it was thought to not be practically solvable at all, much less on a global scale. Irrespective of its currency aspects, many experts believe Bitcoin is brilliant in that it technically made possible what was previously thought impossible. (via Mike Loukides)
- Blue Collar Coder (Anil Dash) — I am proud of, and impressed by, Craigslist’s ability to serve hundreds of millions of users with a few dozen employees. But I want the next Craigslist to optimize for providing dozens of jobs in each of the towns it serves, and I want educators in those cities to prepare young people to step into those jobs. Time for a Massively Multiplayer Online Economy, as opposed to today’s fun economic games of Shave The Have-Nots and Race To The Oligarchy.
Post in Translation, Comic Briefs, Fibre Optics, and Silk Road Financials
- Post Lingo — automatically transcribe incoming emails from foreign tongues. (via Brian McConnell)
- All Briefs Should Now Be in Comic Book Form — does wonders for mass audience acceptance of the arguments. (via Andy Lester)
- Magic Carpet Can Detect and Predict Falls (BBC) — Beneath the carpet is a mesh of optical fibres that detect and plot movement as pressure bends them, changing the light detected at the carpet’s edges. These deflected light patterns help electronics “learn” walking patterns and detect if they are deteriorating, for instance in the elderly. Neat use for fibre optics! (via Sara Winge)
- Travelling the Silk Road (PDF) — A measurement analysis of a large anonymous online marketplace [...] A relatively small “core” of about 60 sellers has been present throughout our measurement interval, while the majority of sellers leaves (or goes “underground”) within a couple of weeks of their ﬁrst appearance. We evaluate the total revenue made by all sellers to approximately USD 1.9 million per month; this corresponds to about USD 143,000 per month in commissions perceived by the Silk Road operators.

Digging into in-app purchase data, Bitcoin draws attention outside tech, PayPal and HomeDepot expand point-of-sale trial.
Study finds that users who wait to make their first in-app purchase are worth more. Also, Bitcoin's popularity is rising, and PayPal expands its point-of-sale program. (Commerce Weekly is produced as part of a partnership between O'Reilly and PayPal.)
Ubiquitous Multitouch, Bitcoin Bust, vim Text Concepts, and Storage Troubles
- OmniTouch: Wearable Interaction Everywhere — compact projector + kinect equivalents in shoulder-mounted multitouch glory. (via Slashdot)
- Price of Bitcoin Still Dropping — currency is a confidence game, and there’s no confidence in Bitcoins since the massive Mt Gox exchange hack.
- vim Text Objects — I’m an emacs user, so this is like reading Herodotus. “On the far side of the Nile is a tribe who eat their babies and give birth to zebras made of gold. They also define different semantics for motion and text objects.”
- Hard Drive Shortage Predicted (Infoworld) — flooding in Thailand has knocked out 25% of the world’s hard drive manufacturing capacity. Interested to see the effects this has on cloud providers. (via Slashdot)
PayPal has a big vision for single sign on, and a reporter searches for Bitcoin's creator.
PayPal Access is a single sign-on tool that enables transactions — and it’s got sweeping ambitions. Elsewhere, a reporter searches for Bitcoin’s developer. (Commerce Weekly is produced as part of a partnership between O’Reilly and PayPal.)
Bitcoin Banks, Journo Ethics, Android and iOS, and Clever Algorithms
- 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).
- Clever Algorithms — book of 45 nature-inspired algorithms, code in Ruby.
Minecraft Emergent Behaviour, Algorithmic 3D Printing, Automated MapReduce Optimization, and Multi-Device Preview
- Anonymity in Bitcoin — TL;DR: Bitcoin is not inherently anonymous. It may be possible to conduct transactions is such a way so as to obscure your identity, but, in many cases, users and their transactions can be identified. We have performed an analysis of anonymity in the Bitcoin system and published our results in a preprint on arXiv. (via Hacker News)
- 3D Printing + Algorithmic Generation — clever designers use algorithms based on leaf vein generation to create patterns for lamps, which are then 3d-printed. (via Imran Ali)

Gamification Critique, BitCoin Trojan, App Store Abandonment, and SSD Rant

- All Your Bitcoins Are Ours (Symantec) — a trojan in the wild that targets the wallet.dat file and transfers your bitcoins out. If you use Bitcoins, you have the option to encrypt your wallet and we recommend that you choose a strong password for this in the event that an attacker is attempting to brute-force your wallet open. (via Hacker News)
- FT Escapes the App Trap (Simon Phipps) — Financial Times dropping their iOS app and moving to HTML5, to escape the App Store commissions. As Simon points out, they’re also losing the sales channel benefits of the App Store. Facebook are doing similar. (via Tim O’Reilly)
- Artur Bergman on SSDs (video) — a short sweary rant he gave at Velocity, laying out the numbers for why you’re an idiot not to use SSDs.
