- 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.

Tracking Bitcoin, Gaming Deflation, Bloat-Aware Design, and Mapping Entity Relationships
- Quantitative Analysis of the Full Bitcoin Transaction Graph (PDF) — We analyzed all these large transactions by following in detail the way these sums were accumulated and the way they were dispersed, and realized that almost all these large transactions were descendants of a single transaction which was carried out in November 2010. Finally, we noted that the subgraph which contains these large transactions along with their neighborhood has many strange looking structures which could be an attempt to conceal the existence and relationship between these transactions, but such an attempt can be foiled by following the money trail in a succinctly persistent way.

- Majority of Gamers Today Can’t Finish Level 1 of Super Mario Bros — Nintendo test, and the President of Nintendo said in a talk, We watched the replay videos of how the gamers performed and saw that many did not understand simple concepts like bottomless pits. Around 70 percent died to the first Goomba. Another 50 percent died twice. Many thought the coins were enemies and tried to avoid them. Also, most of them did not use the run button. There were many other depressing things we noted but I can not remember them at the moment. (via Beta Knowledge)
- Bloat-Aware Design for Big Data Applications (PDF) — (1) merging and organizing related small data record objects into few large objects (e.g., byte buffers) instead of representing them explicitly as one-object-per-record, and (2) manipulating data by directly accessing buffers (e.g., at the byte chunk level as opposed to the object level). The central goal of this design paradigm is to bound the number of objects in the application, instead of making it grow proportionally with the cardinality of the input data. (via Ben Lorica)
- Poderopedia (Github) — originally designed for investigative journalists, the open src software allows you to create and manage entity profile pages that include: short bio or summary, sheet of connections, long newsworthy profiles, maps of connections of an entity, documents related to the entity, sources of all the information and news river with external news about the entity. See the announcement and website.
Open Source Metrics, BitTorrent to TV, Tumblr Value, and Variable Fiction
- Open Source Metrics — Talking about the health of the project based on a single metric is meaningless. It is definitely a waste of time to talk about the health of a project based on metrics like number of software downloads and mailing list activities. Amen!
- BitTorrent To Your TV — The first ever certified BitTorrent Android box goes on sale today, allowing users to stream files downloaded with uTorrent wirelessly to their television. The new set-top box supports playback of all popular video formats and can also download torrents by itself, fully anonymously if needed. (via Andy Baio)
- Tumblr URL Culture — the FOO.tumblr.com namespace is scarce and there’s non-financial speculation. People hoard and trade URLs, whose value is that they say “I’m cool and quirky”. I’m interested because it’s a weird largely-invisible Internet barter economy. Here’s a rant against it. (via Beta Knowledge)
- Design-Fiction Slider Bar of Disbelief (Bruce Sterling) — I love the list as much as the diagram. He lays out a sliding scale from “objective reality” to “holy relics” and positions black propaganda, 419 frauds, design pitches, user feedback, and software code on that scale (among many other things). Bruce is an avuncular Loki, pulling you aside and messing with your head for your own good.
Bitcoin Numbers, Augmenting People with Computers, EBook Creation, and Answering Your Questions
- BitCoin in 2012, By The Numbers — Over the past year Bitcoin’s value when compared to the US Dollar, and most other currencies, increased steadily, though there was a large spike and subsequent dip in August. Interestingly, the current market cap is actually at a peak for 2012, exceeding the spike in August. This can be attributed to the fact that tens of thousands of Bitcoins have been introduced into the economy since August, though now at the slower rate of 25 per block.
- Man-Computer Symbiosis (JCR Licklider) — In short, it seems worthwhile to avoid argument with (other) enthusiasts for artificial intelligence by conceding dominance in the distant future of cerebration to machines alone. There will nevertheless be a fairly long interim during which the main intellectual advances will be made by men and computers working together in intimate association. Fascinating to read this 1960 paper on AI and the software/hardware augmentation of human knowledge work (just as the term “knowledge worker” was coined). (via Jim Stogdill)

Invisible Data Economy, Hacked Value, Open Algorithms Textbook, and Mobile Testing
- Beyond Goods and Services: The Unmeasured Rise of the Data-Driven Economy — excellent points about data as neither good nor service, and how data use goes unmeasured by economists and thus doesn’t influence policy. According to statistics from the Bureau of Economic Analysis, real consumption of ‘internet access’ has been falling since the second quarter of 2011. In other words, according to official U.S. government figures, consumer access to the Internet—including mobile—has been a drag on economic growth for the past year and a half. (via Mike Loukides)
