IoT meets agriculture, Intellistreets, immersive opera, and high-tech pencils

The Radar team does a lot of sharing in the backchannel. Here’s a look at a selection of stories and innovation highlights from around the web that have caught our recent attention. Have an interesting tidbit to contribute to the conversation? Join the discussion in the comments section, send me an email or ping me on Twitter.

  • Pencil — FiftyThree’s new Pencil tool is a super cool gadget that exhibits interesting technology from a software meets hardware perspective. (Via Mike Loukides)
  • littleBits Synth KitlittleBits and Korg have teamed up to bring DIY to music with a modular synthesizer kit. From John Paul Titlow on Fast Company: “Hobbyists have been doing this for many years, either through prepackaged kits or off-the-shelf components. The difference here is that no soldering or wiring is required. Each circuit piece’s magnetized and color-coded end makes them effortlessly easy to snap together and pull apart … Notably, the components of the kit are compatible with other littleBits modules, so it’s possible to build a synthesizer that integrates with other types of sensors, lights, and whatever else littleBits cooks up down the line.” (Via Jim Stogdill)
  • Why Curated Experiences Are The New Future Of Marketing — From immersive opera to extreme kidnapping to a bungee-jumping car, companies are learning that the key to their customers’ attention (and wallets) lies in the experience. From Krisztina “Z” Holly on Forbes: “There is something about a moment in time that can’t be replicated, an experience that is your very own, an adventure with others that is deeply personal and memorable. It is something that can’t be achieved by a high-budget celebrity endorsement or a large ad buy.” (Via Sara Winge)
  • The Internet of things, stalk by stalk — IoT meets agriculture with Air Tractor planes that can change fertilizer mixtures in-flight and the Rosphere farm robot that monitors crops. From Paul Rako on GigaOm: “Sensors on the robot could monitor each and every stalk of corn. Those robots can communicate with each other over a mesh network. A mesh network is like a chat room for gadgets. They identify themselves and their capabilities, and are then a shared resource.” (Via Jenn Webb)
  • What happens in Vegas DOESN’T stay in Vegas — Vegas’ new wireless street light system, Intellistreets, can record video and audio. From the Daily Mail: “The wireless, LED lighting, computer-operated lights are not only capable of illuminating streets, they can also play music, interact with pedestrians and are equipped with video screens, which can display police alerts, weather alerts and traffic information. The high tech lights can also stream live video of activity in the surrounding area. … These new street lights, being rolled out with the aid of government funding, are also capable of recording video and audio.” (Via Tim O’Reilly)

Additionally, at the recent Techonomy conference, Tim O’Reilly and Max Levchin discussed “Innovation and the Coming Shape of Social Transformation” — have a look:

  1. ISS Enjoys Malware — Kaspersky reveals ISS had XP malware infestation before they shifted to Linux. The Gravity movie would have had more registry editing sessions if the producers had cared about FACTUAL ACCURACY.
  2. Big Data Approach to Computational Creativity (Arxiv) — although the “results” are a little weak (methodology for assessing creativity not described, and this sadly subjective line “professional chefs at various hotels, restaurants, and culinary schools have indicated that the system helps them explore new vistas in food”), the process and mechanism are fantastic. Bayesian surprise, crowdsourced tagged recipes, dictionaries of volatile compounds, and more. (via MIT Technology Review)
  3. Go at 4 — recapping four years of Go language growth.
  4. Las Vegas Street Lights to Record Conversations (Daily Mail) — The wireless, LED lighting, computer-operated lights are not only capable of illuminating streets, they can also play music, interact with pedestrians and are equipped with video screens, which can display police alerts, weather alerts and traffic information. The high tech lights can also stream live video of activity in the surrounding area. Technology vendor is Intellistreets. LV says, Right now our intention is not to have any cameras or recording devices. Love that “right now”. Can’t wait for malware to infest it.

« Diffusion du petit guide de la police et la gendarmerie sur les filatures »

« Diffusion du petit guide de la police et la gendarmerie sur les filatures »

#Filature en métro, à pied, en voiture....Techniques de dissimulation et d’approche d’un individu en vu de l’observer ou de l’interpeller, les fonctionnaires de #police savent parfois écrire n’importe quoi sur les réseaux sociaux, en revanche, ils peuvent diffuser des choses particulièrement interessante. Ce petit guide de 11 pages est une véritable mine d’information sur les filatures que peuvent mettre en place les différents services de police et de gendarmerie. C’est digne d’un film d’espionnage mais c’est pourtant bien la réalité. On se demande d’ailleurs pourquoi un document censé rester en interne se retrouve sur la toile....

Bonne lecture.

  1. Raspberry Pi Wireless Attack ToolkitA collection of pre-configured or automatically-configured tools that automate and ease the process of creating robust Man-in-the-middle attacks. The toolkit allows your to easily select between several attack modes and is specifically designed to be easily extendable with custom payloads, tools, and attacks. The cornerstone of this project is the ability to inject Browser Exploitation Framework Hooks into a web browser without any warnings, alarms, or alerts to the user. We accomplish this objective mainly through wireless attacks, but also have a limpet mine mode with ettercap and a few other tricks.
  2. Industrial Robot with SDK For Researchers (IEEE Spectrum) — $22,000 industrial robot with 7 degrees-of-freedom arms, integrated cameras, sonar, and torque sensors on every joint. [...] The Baxter research version is still running a core software system that is proprietary, not open. But on top of that the company built the SDK layer, based on ROS (Robot Operation System), and this layer is open source. In addition, there are also some libraries of low level tasks (such as joint control and positioning) that Rethink made open.
  3. OtherMill (Kickstarter) — An easy to use, affordable, computer controlled mill. Take all your DIY projects further with custom circuits and precision machining. (via Mike Loukides)
  4. go-raft (GitHub) — open source implementation of the Raft distributed consensus protocol, in Go. (via Ian Davis)

  1. Triage — iPhone app to quickly triage your email in your downtime. See also the backstory. Awesome UI.
  2. Webcam Pulse Detector — I was wondering how long it would take someone to do the Eulerian video magnification in real code. Now I’m wondering how long it will take the patent-inspired takedown…
  3. How Microsoft Quietly Built the City of the FutureThe team now collects 500 million data transactions every 24 hours, and the smart buildings software presents engineers with prioritized lists of misbehaving equipment. Algorithms can balance out the cost of a fix in terms of money and energy being wasted with other factors such as how much impact fixing it will have on employees who work in that building. Because of that kind of analysis, a lower-cost problem in a research lab with critical operations may rank higher priority-wise than a higher-cost fix that directly affects few. Almost half of the issues the system identifies can be corrected in under a minute, Smith says.
  4. UDOO (Kickstarter) — mini PC that could run either Android or Linux, with an Arduino-compatible board embedded. Like faster Raspberry Pi but with Arduino Due-compatible I/O.

  1. Administration Strategy on Mitigating the Theft of US Trade Secrets (Whitehouse, PDF) — the Chinese attacks on Facebook, NYT, and other large organisations are provoking policy responses. WSJ covers it nicely. What is this starting? (via Alex Howard)
  2. BodyMedia FitLink — can use this to gather caloric expenditure and sleep restfulness. (via Jonathan Brewer)
  3. Bend Not Break — she had an amazing life but this caught my eye in the Make review: In China, she told me, making and craftsmanship are highly revered, and under Mao, factory jobs were prized. Her experience working in Mao’s factories planted a seed in her mind that sprouted when she sought to create her own company. Rather than launch another internet-based business as was the rage at the time, she wanted to connect software to the physical world. (via Makezine)
  4. DIY Weapons of the Syrian Rebels (The Atlantic) — if WWII France had had X-Box controllers, they’d have been releasing remote controlled homebrew deathmobiles too.

  1. 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.
  2. Travis CIa hosted continuous integration service for the open source community. It is integrated with GitHub.
  3. Chinese Cyber-Espionage Unit (PDF) — exposé of one of China’s Cyber Espionage Units. (via Reddit /r/netsec)
  4. $250 Arduino-Powered Hand Made by a Teenthe 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.

  1. Wireless Substitution (BoingBoing, CDC) — very nice graph showing the decline in landlines/growth in wireless.
  2. Maker’s RowOur mission is to make the manufacturing process simple to understand and easy to access. From large corporations to first time designers, we are providing unparalleled access to industry-specific factories and suppliers across the United States.
  3. mySight (GitHub) — Spectruino analyzer for light spectra in UV/VIS/NIR.
  4. State of the World (Bruce Sterling, John Lebkowsky) — always a delight. Come 2013, I think it’s time for people in and around the “music industry” to stop blaming themselves, and thinking their situation is somehow special. Whatever happens to musicians will eventually happen to everybody. Nobody was or is really much better at “digital transition” than musicians were and are. If you’re superb at digitalization, that’s no great solution either. You just have to auto-disrupt and re-invent yourself over and over and over again.

  1. Improving the Security Posture of Industrial Control Systems (NSA) — common-sense that owners of ICS should already be doing, but which (because it comes from the NSA) hopefully they’ll listen to. See also Wired article on NSA targeting domestic SCADA systems.
  2. Geographic Pricing Online (Wall Street) — Staples, Discover Financial Services, Rosetta Stone, and Home Depot offer discounts if you’re close to a competitor, higher prices otherwise. [U]sing geography as a pricing tool can also reinforce patterns that e-commerce had promised to erase: prices that are higher in areas with less competition, including rural or poor areas. It diminishes the Internet’s role as an equalizer.
  3. Hacker Scouting (NPR) — teaching kids to be safe and competent in the world of technology, just as traditional scouting teaches them to be safe and competent in the world of nature.
  4. pressureNET Data Visualization — open source barometric data-gathering software which runs on Android devices. Source is on GitHub.

  1. Kenyan Women Create Their Own Geek Culture (NPR) — Oguya started spending some Saturday mornings with Colaco and other women, snipping code and poring through hacker cookbooks. These informal gatherings became the Akirachix. Oguya graduated and turned her mobile phone idea into a company called M-Farm. At 25 years old, she now has a staff of 18. And 7,000 African farmers use her app.
  2. Ozone Widget Framework (Github) — open source webapp integrator. The Ozone Widget Framework is released to the public as Open Source Software, because it’s the Right Thing To Do. Also, it was required by Section 924 of the 2012 National Defense Authorization Act. Spook-made, citizen played.
  3. gtypist — open source universal typing tutor. You can learn correct typing and improve your skills by practising its exercises on a regular basis.
  4. Open Source Hardware Bagpipes — to practice your fingerings without actually killing the neighbours. (via Hacked Gadgets)

  1. RebelMouse — aggregates FB, Twitter, Instagram, G+ content w/Pinboard-like aesthetics. It’s like aggregators we’ve had since 2004, but in this Brave New World we have to authenticate to a blogging service to get our own public posts out in a machine-readable form. 2012: it’s like 2000 but now we have FOUR AOLs! We’ve traded paywalls for graywalls, but the walls are still there. (via Poynter)
  2. Data Visualization Course Wiki — wiki for Stanford course cs448b, covering visualization with examples and critiques.
  3. Peristaltic Pump — for your Arduino medical projects, a pump that doesn’t touch the liquid it moves so the liquid can stay sterile.

  2. Mobile is Entertainment (Luke Wroblewski) — 79% of mobile app time is spent on fun, even as desktop web use is declining.
  3. Five UX Research Pitfalls (Elaine Wherry) — I live this every day: Sometimes someone will propose an idea that doesn’t seem to make sense. While your initial reaction may be to be defensive or to point out the flaws in the proposed A/B study, you should consider that your buddy is responding to something outside your view and that you don’t have all of the data.

The MOOC movement is not an indicator of educational evolution

Somehow, recently, a lot of people have taken an interest in the broadcast of canned educational materials, and this practice — under a term that proponents and detractors have settled on, massive open online course (MOOC) — is getting a publicity surge. I know that the series of online classes offered by Stanford proved to be extraordinarily popular, leading to the foundation of Udacity and a number of other companies. But I wish people would stop getting so excited over this transitional technology. The attention drowns out two truly significant trends in progressive education: do-it-yourself labs and peer-to-peer exchanges.

In the current opinion torrent, Clay Shirky considers MOOCs one of the big disruptive technologies of our age, and Joseph E. Aoun, president of Northeastern University, writes (in a Boston Globe subscription-only article) that traditional colleges will have to deal with the MOOC challenge. Jon Bruner points out on Radar that non-elite American institutions could use a good scare (although I know a lot of people whose lives were dramatically improved by attending such colleges). The December issue of Communications of the ACM offers Professor Richard A. DeMillo from the Georgia Institute of Technology assessing the possible role of MOOCs in changing education, along with an editorial by editor-in-chief Moshe Y. Vardi culminating with, “If I had my wish, I would wave a wand and make MOOCs disappear.”

There’s a popular metaphor for this early stage of innovation: we look back to the time when film-makers made the first moving pictures with professional performers by setting up cameras before stages in theaters. This era didn’t last long before visionaries such as Georges Méliès, D. W. Griffith, Sergei Eisenstein, and Luis Buñuel uncovered what the new medium could do for itself. How soon will colleges get tired of putting lectures online and offer courses that take advantage of new media?

Two more appealing trends are already big. One is DIY courses, as popularized in the book Fab by Neil Gershenfeld at the MIT Media Lab. O’Reilly’s own Make projects are part of this movement. Fab courses represent the polar opposite of MOOCs in many ways. They are delivered in small settings to students whose dedication, inspiration, and talent have to match those of the teacher — the course asks a lot of everybody. But from anecdotal reports, DIY courses have been shown to be very powerful growth mechanisms in environments ranging from the top institutions (like MIT) to slums around the world. Teenagers are even learning to play with biological matter in labs such as BioCurious.

Fundamentally, DIY is a way to capture the theory of learning by doing, which goes back at least to John Dewey at the turn of the 20th century. The availability of 3D makers, cheap materials, fab software, and instructions over the Internet lend the theory a new practice.

“I believe in everything never yet said.”–Rainer Maria Rilke, Das Stunden-Buch

The other major trend cracking the foundations of education is peer-to-peer information exchange. This, like learning by doing, has plenty of history. The symposia of Ancient Greece (illustrated in fictional form by Plato) and the Talmudic discussions that underlay the creation of modern Judaism over 2,000 years ago show that human beings have long been used to learning from each other. Peer information exchange raged on centuries later in cafés and salons, beer halls and sewing circles. Experts were important, and everybody could recognize the arrival of a true expert, but he or she was just first among equals. A lot of students who sign up for MOOCs probably benefit from the online discussion forums as much as from the canned lectures and readings.

Wikipedia is a prominent example of peer-to-peer information exchange, and one that promulgates the contributions of experts, but one that also has trouble with sustainability. (They’re holding one of their fund-raisers now, and it’s a good time to donate.) This leads me to ask what business model colleges can apply in the face of both MOOCs and peer-to-peer knowledge. How do you mobilize a whole community to educate each other, while maintaining the value of expertise?

This challenge — not just a business challenge, but really the challenge of tapping expertise effectively — happens to be one that O’Reilly is dealing with in the field of publishing. We introduced the equivalent of filmed stage shows in the mid-1990s when we created the Safari Bookshelf to provide our books on a subscription-based website. The innovation was in the delivery model, which also delivered a shock to a publishing industry dependent on print sales.

But we knew that Safari Bookshelf barely dipped into the power of the web, which has grown more and more with advances in HTML, JavaScript, and mobile devices. Safari Bookshelf is much more than a collection of web pages with book content now. As a training tool, the web has exploded with other experiments. We offer an interactive school of technology also.

So the field of education will probably see lots of blended models along the way. It’s worth noting that proponents of open content have called for licensing models that reinforce the open promise of the courses. Some courses ask students to write their own textbooks and share them — but one asks where they get the information with which to write their peer-produced textbooks. In an earlier article I examined the difficulties of creating free, open textbooks that are actually usable for teaching. Such dilemmas just show that the investment of large amounts of time by experts are still a critical part of education — but applying the broadcast model to them may be less and less relevant.

  1. Tilt-to-Fly Controller and Copter (Kickstarter) — This looks totally awesome and hackable. The controller has a USB port, the protocol is documented, and you can even connect your own electronics payload, like an Arduino, camera, or homebrewed project to the auxiliary serial (UART + power) port.
  2. The Privacy Game (The Open University) — This game is designed to highlight how privacy and consent work online. Players make decisions about which information they reveal, who they reveal it to and why. For example, you may decide to trade some information for gifts when shopping on a website; or you may decide to keep other information secret when posting on a social networking site. (via BoingBoing)
  3. statwing — very easy analysis and visualization of data.
  4. duraconfa collection of hardened configuration files for SSL/TLS services. It’s easy to reduce crypto effectiveness with crappy choices and options, so it’s good to have solid configurations to go from.
