- The Programming Error That Cost Mt Gox 2609 Bitcoins — in the unforgiving world of crypto-currency, it’s easy to miscode and vanish your money.
- Ford Invites Open-Source Community to Tinker Away — One example: Nelson has re-tasked the motor from a Microsoft Xbox 360 game controller to create an OpenXC shift knob that vibrates to signal gear shifts in a standard-transmission Mustang. The 3D-printed prototype shift knob uses Ford’s OpenXC research platform to link devices to the car via Bluetooth, and shares vehicle data from the on-board diagnostics port. Nelson has tested his prototype in a Ford Mustang Shelby GT500 that vibrates at the optimal time to shift.
- Making Sense of Data — Google online course on data literacy.
- Cost-Efficient Continuous Integration at Mozilla — CI on a big project can imply hundreds if not thousands of VMs on Amazon spinning up to handle compiles and tests. This blog post talks about Mozilla’s efforts to reduce its CI-induced spend without reducing the effectiveness of its CI practices.

Open Hardware Designs, Kickstarting SDR, Go Best Practices, and US Code
- Tindie Launches Open Designs and Kickbacks (Tindie) — businesses can manufacture the open design as is, or create products derived from it. Those sellers can then kickback a portion of their sales back to the designer. Tindie will handle the disbursement of funds so it’s absolutely painless. For designers, there are no fees, no hosting costs, just a simple way to reap the benefits of their hard work.
- HackRF (Kickstarter) — an open source software-defined-radio platform to let you transmit or receive any radio signal from 30 MHz to 6000 MHz on USB power.
- Twelve Best Go Practices — to help you get the mindset of Go.
- US Code for Download — in XML and other formats. Waaaay after public resource showed them what needed to be done. First slow step of many fast ones, I hope.
Bitcoin Bundle, HTML Escaping, Open as in Gongkai, and Glass Reflections
- The Well Deserved Fortune of Satoshi Nakamoto — I can’t assure with 100% certainty that the all the black dots are owned by Satoshi, but almost all are owned by a single entity, and that entity began mining right from block 1, and with the same performance as the genesis block. It can be identified by constant slope segments that occasionally restart. Also this entity is the only entity that has shown complete trust in Bitcoin, since it hasn’t spend any coins (as last as the eye can see). I estimate at eyesight that Satoshi fortune is around 1M Bitcoins, or 100M USD at current exchange rate. Author’s credible. (via Hacker News)
- Houdini (Github) — C library for escaping and unescaping UTF-8-encoded HTML, according to OWASP guidelines.
- The $12 Gongkai Phone (Bunnie Huang) — gongkai isn’t a totally lawless free-for-all. It’s a network of ideas, spread peer-to-peer, with certain rules to enforce sharing and to prevent leeching. It’s very different from Western IP concepts, but I’m trying to have an open mind about it.
- Jan Chipchase on Google Glass (All Things D) — Any idiot can collect data. The real issue is how to collect data in such a way that meets both moral and legal obligations and still delivers some form of value. An interesting observation, one of many within this overview of the usability and third-party user experience of Google Glass-like UIs.
In 2013, developers will once again boldly contribute code to projects where their code has never gone before.
Urine Checkins, News Summaries, Zombie Ideas, and Scanner Plans
- Mark Your Territory — Urine integration for Foursquare. (via Beta Knowledge)
- TL;DR — news summaries. Finally.
- Zombie Ideas and Online Instruction — The repeated return of mistaken ideas captures well my experiences with technologies in schools and what I have researched over decades. The zombie idea that is rapidly being converted into policies that in the past have been “refuted with evidence but refuse to die” is: new technologies can cure K-12 and higher education problems of teaching and learning. The most recent incarnation of this revolving-door idea is widespread access to online instruction in K-12 education cyber-charter schools, blended schools where online instruction occurs for a few hours a day, and mandated courses that children and youth have to take.

Tired of waiting, hackers and billionaires alike are building the future they want to see.
DIY Bio Hardware, App Store Numbers, Open Hardware Repository, and Science Startups
- OpenPCR Shipping — A PCR machine is basically a copy machine for DNA. It is essential for most work with DNA, things like exposing fraud at a sushi restaurant, diagnosing diseases including HIV and H1N1, or exploring your own genome. The guy who discovered the PCR process earned a Nobel Prize in 1993, and OpenPCR is now the first open source PCR machine. The price of a traditional PCR machine is around $3,000. This one is $512 and would go well with Ben Krasnow’s Scanning Electron Microscope. Biological tools get closer to hobbyist/hacker prices. (via Gabriella Coleman)
- Apple App Store Figures (Fast Company) — 1 billion apps in a month, 200M iOS users, $2.5B revshare to developers so far (implying a further $5.8B revenue kept by Apple). Another reminder of the astonishing money to be made by riding the mainstreaming of tech: as we move from dumb phones to smart phones, the market for Apple’s products and App Store sales will continue to rise. We’re not at the fighting-for-market-share stage yet, it’s still in the boom. (via Stephen Walli)
- Open Hardware Repository — open source digital hardware projects, such as a tool for generating VHDL/Verilog cores which implement Wishbone bus slaves with certain registers, memory blocks, FIFOs and interrupts. CERN just approved an open license for hardware designs. (via CERN)
- Wingu — SaaS startup to help scientists manage, analyze, and share data. Recently invested by Google, it’s one of several startups for scientists, such as Macmillan’s Digital Science which is run by Timo Hannay who is one of the convenors of Science Foo Camp. (via Alex Butler)
Bounty Paid, C Archived, Blind Queried, and Links Shared
- Open Kinect — less than a week after the bounty for developing an open source driver for Microsoft’s Kinect controller was announced, it is claimed. libfreenect is the software.
- CCAN — the Comprehensive C Archive Network.
- TextCAPTCHAs — simple questions, written in English, that are accessible to blind users.
- F1 — Mozilla browser extension for sharing links via Twitter, Facebook, and Gmail. (via Chris Blizzard on Twitter)
Chrome Extensions in Firefox, AUI Opened, Closing Open Hardware, Fixing Science Metrics
- Chrome Extensions Manager for Firefox — lets you run Chrome extensions in Firefox. I don’t think, though, that people choose Chrome over Firefox for the extensions (quite the opposite, in fact).
- Open Source Ethics and Dead End Derivatives — open source hardware is dealing with the problem of people changing open source designs but not publishing their modified source. Open source software hasn’t found an efficient and reproducible mechanism for dealing with this, though I’d love to be shown one. (via bre on Twitter)
- Let’s Make Science Metrics More Scientific (Nature) — excellent paper about the problem of the metrics for measuring scientific performance are based around papers and citations, but fail to take into account teaching, mentoring, communicating, etc. (via dullhunk on Twitter)
Hardware, open source, and AI today:
- Geek Tour China 2009 — how did I miss this? Bunnie Huang has led a tour of China manufacturing for hardware hacking geeks. Read the blog posts from participants: here, here, here, here, and here. Just go ahead and add these bloggers to your feed reader: sweet sweet candy they post. My favourite: American Shanzai, asking where are the USA hackers like the Chinese who make working phones out of packets of cigarettes? But read the posts for giant single-digit LED clocks, markets of components from torn-down phones, and 280km of velcro/day machines.
- Open Source Hardware Central Bank — an interesting idea to fund the manufacture of larger runs than would be possible with self-funding, so as to achieve modest economies of scale. “Looking at Open Source Software, it’s a thriving ecosystems of communities, projects, and contributors. There are a few companies, but they mostly offer “paid-for” services like consulting, tech support, or custom code/build-to-order functionality. I’d like the same for Open Source Hardware. I’d like the money problem to go away for small contributors like me and others. And I’d like to help guys like Chris and Mike and Mark and David and Jake build more cool stuff because it’s fun.”
- Wolfram Alpha — everyone is skeptical because it smells like AI windmill tilting mixed with “my pet algorithms are the keys to the secrets of the universe!”, but it’ll be interesting to see what it looks like when it launches in May. “But what about all the actual knowledge that we as humans have accumulated? [...] armed with Mathematica and NKS I realized there’s another way: explicitly implement methods and models, as algorithms, and explicitly curate all data so that it is immediately computable. [...] I wasn’t at all sure it was going to work. But I’m happy to say that with a mixture of many clever algorithms and heuristics, lots of linguistic discovery and linguistic curation, and what probably amount to some serious theoretical breakthroughs, we’re actually managing to make it work. Pulling all of this together to create a true computational knowledge engine is a very difficult task.”
- Open Source, Open Standards, and Reuse: Government Action Plan — “So we consider that the time is now right to build on our record of fairness and achievement and to take further positive action to ensure that Open Source products are fully and fairly considered throughout government IT; to ensure that we specify our requirements and publish our data in terms of Open Standards; and that we seek the same degree of flexibility in our commercial relationships with proprietary software suppliers as are inherent in the open source world.” Great news from the UK!
