Using Silk Road — exploring the transactions, probability of being busted, and more. Had me at the heading Silk Road as Cyphernomicon’s black markets. Estimates of risk of participating in the underground economy.
Travis CI — a hosted continuous integration service for the open source community. It is integrated with GitHub.
$250 Arduino-Powered Hand Made by a Teen — the third version of his robotic hand. The hand is primarily made with 3D printing, with the exception of motors, gears, and other hardware. The control system is activated by flexing a pre-chosen muscle, such as curling your toes, then the movement is chosen and controlled by a series of eyeblinks and an EEG headset to measure brainwaves. The most remarkable part is that the hand costs a mere $250.

Ed Startups in a Nutshell (Dan Meyer) — I couldn’t agree with Dan more: The Internet is like a round pipe. Lecture videos and machine-scored exercises are like round pegs. They pass easily from one end of the pipe to the other. But there are square and triangular pegs: student-student and teacher-student relationships, arguments, open problems, performance tasks, projects, modeling, and rich assessments. These pegs, right now, do not flow through that round pipe well at all.
CA Assembly Bill No. 292 — This bill would provide that the full text of the California Code of Regulations shall bear an open access creative commons attribution license, allowing any individual, at no cost, to use, distribute, and create derivative works based on the material for either commercial or noncommercial purposes.

The Inside Story of PACER (Ars Technica) — PACER has become a cash cow for the judicial branch, generating $100 million in profits the court has plowed into non-PACER IT projects. (via BoingBoing)
Manipulating Memory for Fun and Profit (PDF) — It is a common belief that RAM loses its content as soon as the power is down. This is wrong, RAM is not immediately erased. It may take up to several minutes in a standard environment, even if the RAM is removed from the computer. And it may last much longer if you cool the DRAM chips. With a simple dusty spraying at -50°C, your RAM data can survive more that 10 minutes. If you cool the chips at -196°C with liquid nitrogen, data are held for several hours without any power.
The Indiepocalypse (Andy Baio) — We’re at the beginning of an indiepocalypse — a global shift in how culture is made, from a traditional publisher model to independently produced and distributed works.
China, GitHub, and MITM — No browser would prevent the authorities from using their ultimate tool though: certificates signed by the China Internet Network Information Center. CNNIC is controlled by the government through the Ministry of Industry and Information Technology. They are recognized by all major browsers as a trusted Certificate Authority. If they sign a fake certificate used in a man-in-the-middle attack, no browser will warn of any usual activity. The discussion of how GitHub (or any site) could be MITM’d is fascinating, as is the pros and cons for a national security agency to coopt the certificate-signing NIC.
Chinese Attack UAV (Alibaba) — Small attack UAV is characterized with small size, light weight, convenient carrying, rapid outfield expansion procedure, easy operation and maintenance; the system only needs 2-3 operators to operate, can be carried by surveillance personnel to complete the attack mission.

TruthTeller Prototype (Washington Post) — speech-to-text, then matches statements against known facts to identify truth/falsehoods. Still a prototype but I love that, in addition to the Real Time Coupon Specials From Hot Singles Near You mobile advertising lens, there might be a truth lens that technology helps us apply to the world around us.
Money from Music: Survey Evidence on Musicians’ Revenue and Lessons About Copyright Incentives — 5,000 American musicians surveyed, For most musicians, copyright does not provide much of a direct financial reward for what they are producing currently. The survey findings are instead consistent with a winner-take-all or superstar model in which copyright motivates musicians through the promise of large rewards in the future in the rare event of wide popularity. This conclusion is not unfamiliar, but this article is the first to support it with empirical evidence on musicians’ revenue. (via TechDirt)
Max Levchin’s DLD13 Keynote — I believe the next big wave of opportunities exists in centralized processing of data gathered from primarily analog systems. […] There is also a neat symmetry to this analog-to-digtail transformation — enabling centralization of unique analog capacities. As soon as the general public is ready for it, many things handled by a human at the edge of consumption will be controlled by the best currently available human at the center of the system, real time sensors bringing the necessary data to them in real time.
DroneNet: How to Build It (John Robb) — It’s possible to break the FAA’s “line of sight” rules regarding drones right now and get away with it to enable fast decentralized growth. This strategy works. e.g. PayPal flagrantly broke banking laws and regulations in order to out-compete a field of competitors that decided to follow the law. (via Daniel Bachhuber)
How to Make a BOM (Bunnie Huang) — yet more very useful howto information for people looking into Chinese (or other) manufacturing.

Credibility Ranking of Tweets During High Impact Events (PDF) — interesting research. Situational awareness information is information that leads to gain in the knowledge or update about details of the event, like the location, people affected, causes, etc. We found that on average, 30% content about an event, provides situational awareness information about the event, while 14% was spam.

The Commodore 64 — interesting that Chuck Peddle (who designed the 6502) and Bob Yannes (who designed the SID chip) are still alive. This article safely qualifies as Far More Than You Ever Thought You Wanted To Know About The C64 but it is fascinating. The BASIC housed in its ROM (“BASIC 2.0″) was painfully antiquated. It was actually the same BASIC that Tramiel had bought from Microsoft for the original PET back in 1977. Bill Gates, in a rare display of naivete, sold him the software outright for a flat fee of $10,000, figuring Commodore would have to come back soon for another, better version. He obviously didn’t know Jack Tramiel very well. Ironically, Commodore did have on hand a better BASIC 4.0 they had used in some of the later PET models, but Tramiel nixed using it in the Commodore 64 because it would require a more expensive 16 K rather than 8 K of ROM chips to house.
What Was It Like to Browse the Web in the 90s? (Quora) — it was awesome, because the alternative was television. Couple of whiny “you won’t believe how hard we had it” posts, from people who obviously believe that everyone in history has been miserable because they don’t have it as good as we do now. And, thus, by extension, we are miserable because we don’t have it as good as future generations of silver-robot-bearing flying-car-driving humans.
Be a Good Dictator (Rowan Simpson) — There is no shortage of advice online about how to be a good designer or a good software developer. But what about advice for those who aspire to be good product dictators? Guidance seems pretty thin on the ground. […] Being a deep expert in just one area is not enough for good dictators. You need to be a polymath living at an intersection.
Hardware is Dead — 7-inch tablet, Wi-Fi only with all the attributes of a good tablet. Capacitive touchscreen. Snappy processor. Front facing camera. 4GB of internal memory and an expandable memory slot. for USD75. At these levels there is almost no profit margin left in the hardware business. A $45 tablet is cheap enough to be an impulse purchase at the check-out line in Best Buy. A $45 price puts tablets within reach of a whole host of other activities not traditionally associated with computers. (via Steve Bowbrick)
Car Transmissions and Syncromesh (YouTube) — cheesy old Chevy educational movie that does a great job of explaining how manual transmissions work. Such videos were the screencasts for the auto DIY folks. (via Nat Friedman)
