Analytics vs Learning, Reproducible Science, Ramping up Military Internet Attacks, and Compressed Sensing
- Analytics for Learning — Since doing good learning analytics is hard, we often do easy learning analytics and pretend that they are good instead. But pretending doesn’t make it so. (via Dan Meyer)
- Reproducible Research — a list of links to related work about reproducible research, reproducible research papers, etc. (via Stijn Debrouwere)
- Pentagon Deploying 100+ Cyber Teams — The organization defending military networks — cyber protection forces — will comprise more than 60 teams, a Pentagon official said. The other two organizations — combat mission forces and national mission forces — will conduct offensive operations. I’ll repeat that: offensive operations.
- Towards Deterministic Compressed Sensing (PDF) — instead of taking lots of data, compressing by throwing some away, can we only take a few samples and reconstruct the original from that? (more mathematically sound than my handwaving explanation). See also Compressed sensing and big data from the Practical Quant. (via Ben Lorica)
Cheap Attack Drones, Truth Filters, Where Musicians Make Money, and Dynamic Pricing From Digitized Analogue Signals
- 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. (via BoingBoing)
- 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.
Statistical Fallacies, Sensors via Microphone, Peak Plastic, and Go Web Framework
- Common Statistical Fallacies (Flowing Data) — once you know to look for them, you see them everywhere. Or is that confirmation bias?
- Project Hijack — Hijacking power and bandwidth from the mobile phone’s audio interface.
Creating a cubic-inch peripheral sensor ecosystem for the mobile phone.
- Peak Plastic — Deb Chachra points out that if we’re running out of oil, that also means that we’re running out of plastic. Compared to fuel and agriculture, plastic is small potatoes. Even though plastics are made on a massive industrial scale, they still account for less than 10% of the world’s oil consumption. So recycling plastic saves plastic and reduces its impact on the environment, but it certainly isn’t going to save us from the end of oil. Peak oil means peak plastic. And that means that much of the physical world around us will have to change. I hadn’t pondered plastics in medicine before. (via BoingBoing)
- web.go (GitHub) — web framework for the Go programming language.
Tricorder, Microsoft and Open Source, Crime is Freedom's Contra, and Government Cybercrime
- Tricorder Project — open sourced designs for a tricorder, released as part of the Qualcomm Tricorder X Prize. (via Slashdot)
- Microsoft’s New Open Sourced Stacks (Miguel de Icaza) — not just open sourced (some of the code had been under MS Permissive License before, now it’s Apache) but developed in public with git: ASP.NET MVC, ASP.NET Web API, ASP.NET Web Pages v2. The Azure SDK is also on github.
- In An Internet Age, Crime is Essential to Freedom (Donald Clark) — when a criminal asks: “How do I secure payment and store my ill-gotten gains”, somewhere else, a refugee asks: “How can I send funds back to a relative such that they can’t be traced to me”.
- NSA: China Behind RSA Attacks (Information Week) — I can argue both sides about whether government cloud services are a boon or a curse for remote information thieves. Looking forward to seeing how it plays out.
Crowdsourced Monitoring, DIY Neurobio, A Plethora of Memory Stick Computers
- Crowdsourcing Radiation Data in Japan (Freaklabs) — wardriving pollution detection.
- Backyard Brains — measuring electrical activity of a neuron in a cockroach leg. Astonishing how much science is within the reach of backyard hackers now. (via BoingBoing)
- Cotton Candy Stick Pre-Orders — a $200 Android computer on a USB stick, with HDMI out etc.
- Raspberry Pi Launches — $35 USB+CPU+video+audio ships. Interesting that both of these have come to fruition at the same time. Something is in the air. How will the world change when every memory stick is a computer, not just every phone?
DNS Benchmarking, Intro to Macroeconomics, Materials-Sensing Cameras, and 3D Printing Lab Messed Around
- Namebench (Google Code) — hunts down the fastest DNS servers for your computer to use. (via Nelson Minar)
- Primer on Macroeconomics (Jig) — reading suggestions for introductions to macroeconomics suitable to understand the financial crisis and proposed solutions. (via Tim O’Reilly)
- Smarter Cameras Plumb Composition — A new type of smarter camera can take a picture but also assess the chemical composition of the objects being imaged. This enables automated inspection systems to discern details that would be missed by conventional cameras. Interesting how cameras are getting smarter: Kinect as other significant case in point. (via Slashdot)
- Not So Open — 3D printing lab at the University of Washington had to stop helping outsiders because of a crazy new IP policy from the university administration. These folks were doing amazing work, developing and sharing recipes for new materials to print with (iced tea, rice flour, and more) (via BoingBoing)
Emotional Phone, Standup Desk, Mobile Sensors, and eBook Travails
- Samsung Develops Emotion-Sensing Smartphone (ExtremeTech) — By analyzing how fast you type, how much the phone shakes, how often you backspace mistakes, and how many special symbols are used, the special Galaxy S II can work out whether you’re angry, surprised, happy, sad, fearful, or disgusted, with an accuracy of 67.5% From a research paper from a research group on an unannounced product. Nice idea and clever use of incidental data, though 2/3 accuracy isn’t something to write home about. Reminds me of Sandy Pentland‘s Reality Mining. (via James Governor)
- The $40 Standup Desk — we’ve solved the usability of software, but hardware remains stubbornly dangerous to use. There’s a reason nobody refers to “laptops” any more (if you use them on your lap, you might as well call them “wristkillers”).
- funf — an extensible sensing and data processing framework for mobile devices being developed at the MIT Media Lab [...] an open source, reusable set of functionalities, enabling the collection, uploading, and configuration of a wide range of data types. LGPL, Android.
- eBook Publishing Isn’t That Easy — list of the things you have to worry about when you self-publish. This line is gold: Locating a distributor. Amazon pays me 17 bucks for a 50-dollar book. Can you say “assholes?” LuLu pays me 43 bucks, but only if you buy on their site. Do the math. Platform vendors own authors and small publishers. (via Josh Clark)
Finland Schools, Open Source Prezi, Debit Cards for Hackers, and Sensor Startups
- What Americans Keep Ignoring About Finland’s School Success (The Atlantic) — Accountability is something that is left when responsibility has been subtracted. This is a magnificent article, you should read it. (via Juha Saarinen)
- impress.js (github) — MIT-licensed Prezi-like presentation tool, built using CSS3 3d transforms. I’ve never been happy with the Prezi because I fear data lock-in. This might be a way forward. (via Hacker News)
- Facebook Offers Debit Cards to White Hat Hackers (CNet) — paying vulnerability bounties without handing out cash. I figure it’s the start of a loyalty program. Will Facebook learn what the hackers spent the money on? Interesting possibilities opened up here.
- Green Goose — interesting startup selling consumer sensor hardware. My intuition is that we’re platforming too soon: that we need a few individual great applications of the sensors to take off, then we can worry about rationalising hardware in our house. The biggest problem seems to me that we’re talking about “sticking sensors on milk cartons” rather than solving an actual problem someone has. (“There are no sensors on my milk cartons” is not an oft-heard lament)
Hadoop 1.0, Approximation Wiki, Printer Firmware Attacks, and Cotton Circuits
- Hadoop Hits 1.0 — open source distributed computation engine, heavily used in big data analysis, hits 1.0.
- Sparse and Low-Rank Approximation Wiki — interesting technique: instead of sampling at 2x the rate you need to discriminate then compressing to trade noise for space, use these sampling algorithms to (intelligently) noisily sample at the lower bit rate to begin with. Promises interesting applications particularly in for sensors (e.g., the Rice single pixel camera). (via siah)
- Rise of Printer Malware — firmware attacks embedded in printed documents. Another reminder that not only is it hard to write safe software, your mistakes can be epically bad. (via Cory Doctorow)
- Electric Circuits and Transistors Made From Cotton — To make it conductive, the researchers coated cotton threads in a variety of other materials. To make conductive “wires,” the team coated the threads with gold nanoparticles, and then a conductive polymer. To turn a cotton wire into a semiconductor, it was dipped in another polymer, and then a further glycol coating to make it waterproof. Neat materials hack that might lend a new twist to wearables.
