- The Open Spending Data that Isn’t (OKFN) — the UK government mandated councils release details of expenditure over 500 pounds in size. Councils have been sending data to a proprietary service and claiming this is releasing it. Everyone needs to realise that government must always wholesale its data (offer bulk downloads), even when it doesn’t retail that data (offer useful visualisation or analysis tools for it).
- SenseAware — sensors for shipping that wirelessly report back where they are, whether there’s light (i.e., has the container been opened), what the temperature is. (via data4all on Twitter)
- Open Science, Open Data, Open Methods (Ben Goldacre) — open data is sometimes no use unless we also have open methods. (via OKFN)
- Sones — cross-platform open source graph database built on Mono.
ENTRIES TAGGED "sensor networks"
How satellites and sensors can assess the health of crops.
Many satellites capture everything from ocean temperatures, to land reflectance at the surface of the Earth, to global chlorophyll production. Here's a look at how that data can reveal the condition of a country's crops.
Data and low-cost sensor networks can spot extreme weather before it hits.
Identifying extreme weather patterns can minimize impact when that weather arrives. But to improve long-range forecasts, we'll need to create environmental sensor networks out of phones, satellites and other technology.
Data Wholesaling, Sensor Networks, Transparent Science, and a Graph Database
- Comparing genomes to computer operating systems in terms of the topology and evolution of their regulatory control networks (PNAS) — paper comparing structure and evolution of software design (exemplified by the Linux operating system) against biological systems (in the form of the e. coli bacterium). They found software has a lot more “middle manager” functions (functions that are called and then in turn call) as opposed to biology, where “workers” predominate (genes that make something, but which don’t trigger other genes). They also quantified how software and biology value different things (as measured what persists across generations of organisms, or versions of software): Reuse and persistence are negatively correlated in the E. coli regulatory network but positively correlated in the Linux call graph[...]. In other words, specialized nodes are more likely to be preserved in the regulatory network, but generic or reusable functions are persistent in the Linux call graph. (via Hacker News)
- Virtual Keyboards in Google Search — rolling out virtual keyboards across all Google searches. Very nice solution to the problem of “how the heck do I enter that character on this keyboard?”. (via glynmoody on Twitter)
- Information and Quantum Systems Lab at HP — working on the mathematical and physical foundations for the technologies that will form a new information ecosystem, the Central Nervous System for the Earth (CeNSE), consisting of a trillion nanoscale sensors and actuators embedded in the environment and connected via an array of networks with computing systems, software and services to exchange their information among analysis engines, storage systems and end users.

CS Epigrams, Star Trek Made Real, Python Filings, and Difficult Games
- Epigrams in Programming — all from the remarkable Alan Perlis. By the time I learned that he was responsible for such gems as “Syntactic sugar causes cancer of the semicolon”, “A language that doesn’t affect the way you think about programming, is not worth knowing”, and “Around computers it is difficult to find the correct unit of time to measure progress. Some cathedrals took a century to complete. Can you imagine the grandeur and scope of a program that would take as long?”, he had died and I never had a chance to meet him. “The best book on programming for the layman is “Alice in Wonderland”; but that’s because it’s the best book on anything for the layman.”. (via Hacker News)
- Tricorder for Android — app that shows all the info from the sensors: local magnetic field, RF, acceleration, sound, etc. They really need a designer to make this look more like Star Trek than an Apple ][c program. (via attercop on Delicious)
- Will Wall Street Require Python — with Release 33-9117, the SEC is considering substitution of Python or another programming language for legal English as a basis for some of its regulations. Reminds me of Charlie Stross’s “Accelerando” where companies bylaws are written in Python and largely autonomous.
- Hatetris — game of Tetris that deliberately gives you the most difficult pieces. I love inversions like this, which present their own algorithmic challenges distinct from the original’s.
Load Testing, Chinese Manufacturing, Heroic Forking, and Ubicomp
- Tsung — GPLed multi-protocol (HTTP, PostgreSQL, MySQL, WebDAV, SOAP, XMPP) load tester written in Erlang.
- Myth of China’s Manufacturing Prowess — The latest data shows [...] that the United States is still the largest manufacturer in the world. In 2008, U.S. manufacturing output was $1.8 trillion, compared to $1.4 trillion in China (UN data. China’s data do not separate manufacturing from mining and utilities. So the actual Chinese manufacturing number should be much smaller). Also contains pointers to an interesting discussion of lack of opportunities for college grads in China.
- OpenSSO and the Value of Open Source — Oracle are removing all open source downloads and wiki mentions, leaving only the enterprise OpenSSO product on their web site. A Norwegian company has stepped in and will continue the open source project. This is essentially a fork, but for the forces of good. (via normnz on Twitter)
- The Internet of Things — 5m video on sensor networks, etc. (via imran on Twitter)
While the iPhone doesn’t ship nearly as much as its humbler brethren – the iPhone opened up many minds about the potential of phones to do a whole lot more than talk. In that regard it is a peek into the future. The iPhone is a rich portable computer with onboard sensors. Specifically, it is a location-aware (GPS), motion-aware (accelerometer),…
Ongoing Palm Fail, YouTube Numbers, Plugin Patent Pain, Bivalve-Oriented Architecture
- Followup to jwz’s Palm App Store Fiasco — redux: still nothing concrete from Palm, but they’re saying they’ll create a second-rate app store into which open source apps will go (along with apps that Palm hasn’t reviewed).
- Schmidt on YouTube — the interesting bit for me was Every minute, more than 10 hours of video is uploaded to the site.
- Company that won $585M from Microsoft sues Apple, Google – The infamous ’906 patent granted to Eolas and the University of California was one of the first patents to get the young online tech scene going in 1998. The patent addresses third-party browser plug-ins to run various forms of media as an “embedded program object”—essentially a program that runs within another program. Eolas promptly sued Microsoft for its implementation of ActiveX in Internet Explorer, which set in motion a years-long legal battle between the two companies. and won $585M, now they’re suing many large Internet companies.

- IBM Uses Mussels as Sensor Network — Concerned with the environmental and revenue impacts of leaks during oil drilling, StatOil sought an innovative and automated way to detect leaks. They wanted to replace a manual process that included deep sea drivers. StatOil’s innovation, they attached RFID tags to the shells of blue mussels. When the blue mussels sense an oil leak, they close which prompts the RFID tags to emit closure events. In response to the events, the drilling line is automatically stopped. And, in case you are wondering, this is of no harm to the blue mussels. (via monkchips on Twitter)

- TwitterMood — using Twitter as a giant mood sensor for the world (see also temporal correlations, via kellan on delicious).
- What Will Remain of Us — The sea that brought trade to Dunwich was not entirely benevolent. The town was losing ground as early as 1086 when the Domesday Book, a survey of all holdings in England, was published; between 1066 and 1086 more than half of Dunwich’s taxable farmland had washed away. Major storms in 1287, 1328, 1347, and 1740 swallowed up more land. By 1844, only 237 people lived in Dunwich. Today, less than half as many reside there in a handful of ruins on dry land.

- The Three Key Parts of Stories You Don’t Usually Get — In reality, these longstanding facts provide the true foundation of journalism. But in practice, they play second-fiddle to the news, condensed beyond all meaning into a paragraph halfway down in a news story, tucked away in a remote corner of our news sites. Take a look at that WaPo page again. Currently, a link sits on the far right side of the page, a third of the way down, labeled “What you need to know.” Click on that link, and you’re taken here: a linkless, five-paragraph blog post from May. This basically captures our approach to providing the necessary background to follow the news.
- Eulogy to _why — a pseudonymous Ruby character, _why the Lucky Stiff, recently vanished from the net: all his sites and accounts were deleted. It’s possible this is because someone tried to identify him, it’s possible that his accounts were hacked. Either way, this is a touching tribute to him from John Resig. I for one would like to see more appreciation while the people are still around. Today, tell two good people that you enjoy what they do. You know you can.
