IoT Struggle, Embedded Tools, Download Accelerator, and Comms Smog

  1. The Epic Struggle of the Internet of Things — a Bruce Sterling Kindle single, a powerfully-written challenge to the presumed-benevolent technology-pervaded universe that we label “the Internet of Things”. The Internet of Things is not about a talking refrigerator, because that is the old-fashioned consumer retail world of electrical white goods. It’s an archaic concept, like software bought in a plastic-wrapped box from a shelf. The genuine Internet of Things wants to invade that refrigerator, measure it, instrument it, monitor any interactions with it; it would cheerfully give away a fridge at cost.
  2. mbeddra set of integrated and extensible languages for embedded software engineering, plus an IDE. It supports implementation, testing, verification and process aspects. It integrates with command-line build tools and integration servers, as well as file-based version control systems. Nice to see something beyond webdev getting tools love.
  3. Replace wget With axel — download accelerator, aka a parallel wget for situations where the fetched file has multiple servers.
  4. Photos From When Cables Crowded The Skies (io9) — the communication age’s equivalent of the industrial revolution’s smog.

Antilogs, Waitbots, Interactive Interactive Visualisation Book, IoTbot

  1. AntilogsThere are companies before you who have done something like you want to do that you can copy from, and others who have also done something similar, but that you choose not to copy from. These are your analogs and antilogs respectively.
  2. Korean Meal-Transport Robot (RoboHub) — the hyphen is important. It transports all meals, not just Korean ones. Interesting not only grammatically, but for the gradual arrival of the service robot.
  3. Interactive Data Visualisation for the Web — online (interactive, even) version of the O’Reilly book by Scott Murray.
  4. wit.aiNatural language processing for the Internet of Things. Startup, racing to build strategic value beyond “have brought voice recognition to irc bots and aimed it at Internet of Things investors.”

Smarter buildings through data tracking

Buildings are ready to be smart — we just need to collect and monitor the data.

Buildings, like people, can benefit from lessons built up over time. Just as Amazon.com recommends books based on purchasing patterns or doctors recommend behavior change based on what they’ve learned by tracking thousands of people, a service such as Clockworks from KGS Buildings can figure out that a boiler is about to fail based on patterns built up through decades of data.

I had the chance to be enlightened about intelligent buildings through a conversation with Nicholas Gayeski, cofounder of KGS Buildings, and Mark Pacelle, an engineer with experience in building controls who has written for O’Reilly about the Internet of Things. Read more…

Editor’s note: this article is part of a series exploring the role of networking in the Internet of Things.

Three types of networking topologies are utilized in the Internet-of-Things: point-to-point, star, and mesh networking. To provide a way to explore the attributes and capabilities of each of these topologies, we defined a hypothetical (but realistic) application in the building monitoring and energy management space and methodically defined its networking requirements.

Let’s pull it all together to make a network selection for our building monitoring application. As described previously, the application will monitor, analyze, and optimize energy usage throughout the user’s properties. To accomplish this, monitoring and control points need to be deployed throughout each building, including occupancy and temperature sensors. Sensor data will be aggregated back to a central building automation panel located in each building. A continuous collection of data will provide a higher resolution of temperature and occupancy information, thus rendering better insight into HVAC performance and building utilization patterns. Comparison of energy utilization throughout the portfolio of properties allows lower performing buildings to be flagged.

Data Storytelling Tools, Massive Dataset Mining, Failed Crowdsourcing, and IoT Networking

  1. MisoDataset, a JavaScript client-side data management and transformation library, Storyboard, a state and flow-control management library & d3.chart, a framework for creating reusable charts with d3.js. Open source designed to expedite the creation of high-quality interactive storytelling and data visualisation content.
  2. Mining of Massive Datasets (PDF) — book by Stanford profs, focuses on data mining of very large amounts of data, that is, data so large it does not fit in main memory. Because of the emphasis on size, many of our examples are about the Web or data derived from the Web. Further, the book takes an algorithmic point of view: data mining is about applying algorithms to data, rather than using data to “train” a machine-learning engine of some sort.
  3. Lessons from Iceland’s Failed Crowdsourced Constitution (Slate) — Though the crowdsourcing moment could have led to a virtuous deliberative feedback loop between the crowd and the Constitutional Council, the latter did not seem to have the time, tools, or training necessary to process carefully the crowd’s input, explain its use of it, let alone return consistent feedback on it to the public.
  4. Thread a ZigBee Killer?Thread is Nest’s home automation networking stack, which can use the same hardware components as ZigBee, but which is not compatible, also not open source. The Novell NetWare of Things. Nick Hunn makes argument that Google (via Nest) are taking aim at ZigBee: it’s Google and Nest saying “ZigBee doesn’t work”.

OCR in Javascript, Insecure IoT, USB Considered Insecure, and Use AdBlock Plus

  1. Ocrad.js — open source OCR in Javascript, a port of GNU Ocrad software.
  2. HP’s IoT Security Research (PDF) — 70% of devices use unencrypted network services, 90% of devices collected at least one piece of personal information, 60% of those that have UIs are vulnerable to things like XSS, 60% didn’t use encryption when downloading software updates, …
  3. USB Security Flawed From Foundation (Wired) — The element of Nohl and Lell’s research that elevates it above the average theoretical threat is the notion that the infection can travel both from computer to USB and vice versa. Any time a USB stick is plugged into a computer, its firmware could be reprogrammed by malware on that PC, with no easy way for the USB device’s owner to detect it. And likewise, any USB device could silently infect a user’s computer. “It goes both ways,” Nohl says. “Nobody can trust anybody.” [...] “In this new way of thinking, you can’t trust a USB just because its storage doesn’t contain a virus. Trust must come from the fact that no one malicious has ever touched it,” says Nohl. “You have to consider a USB infected and throw it away as soon as it touches a non-trusted computer. And that’s incompatible with how we use USB devices right now.”
  4. AdBlock vs AdBlock Plus — short answer: the genuinely open source AdBlock Plus, because AdBlock resiled from being open source, phones home, has misleading changelog entries, …. No longer trustworthy.

Jeremy Rifkin unveils a return to the local in an interconnected future

Internet of Things, local energy sources, and online collaboration underlie the Zero Marginal Cost Society.

Cube_self-folding_strand

Stratasys’ Education, R&D departments and MIT’s Self-Assembly Lab are researching 4D printing — manufacturing one-off objects that can change their shapes or other physical characteristics in response to their environment. (View the video.)

Jeremy Rifkin is always predicting an avalanche of change: substitutes for human labor in The End of Work, pervasive genetic engineering in Algeny, and so on. Several interlocking themes run through his latest book, The Zero Marginal Cost Society. Behind everything lies the renewed importance of local resources: local energy production, local manufacturing, local governance. And the Internet that ties us all together (evolving into the Internet of Things) will, ironically, bolster local power.

Distributed Systems Design 101, Patent Trolls, Intel's Half a Billion from IoT, and Google's Project Zero.

  1. Inside bit.ly’s Distributed Systems — this is a 101 for modern web distributed systems design.
  2. Patent Trolls are Now 67% of New Patent Lawsuits in USA (WaPo) — data from PwC.
  3. Intel Made Half a Billion from Internet of Things Last Year (Quartz) — half a billion here, half a billion there, pretty soon it adds up to real money.
  4. Google’s Project Zero (Wired) — G pays a team to attack common software and report the bugs to the manufacturer. Interesting hypothesis about how the numbers inbalance between Every Russian 14 Year Old and this small team doesn’t matter: modern hacker exploits often chain together a series of hackable flaws to defeat a computer’s defenses. Kill one of those bugs and the entire exploit fails. That means Project Zero may be able to nix entire collections of exploits by finding and patching flaws in a small part of an operating system, like the “sandbox” that’s meant to limit an application’s access to the rest of the computer. ”On certain attack surfaces, we’re optimistic we can fix the bugs faster than they’re being introduced,” Hawkes says. “If you funnel your research into these limited areas, you increase the chances of bug collisions.”

Governments can bridge costs and services gaps with sensor networks

Government sensor networks can streamline processes, cut labor costs, and improve services.

Contributing authors: Andre Bierzynski and Kevin Chrapaty.

Screenshot from the Waze app.

What if government agencies followed in the footsteps of Waze, a community-driven mobile phone app that collects location data through GPS and allows its users to report accidents and traffic jams, providing real-time, location-specific traffic alerts?

It’s not news to anyone who works in government that we live in a time of ever-tighter budgets and ever-increasing needs. The 2013 federal shutdown only highlighted this precarious situation: government finds it increasingly difficult to summon the resources and manpower needed to meet its current responsibilities, yet faces new ones after each Congressional session.

Sensor networks are an important emerging technology that some areas of government already are implementing to bridge the widening gap between the demand to reduce costs and the demand to improve services. The Department of Defense, for instance, uses RFID chips to monitor its supply chain more accurately, while the U.S. Geological Survey employs sensors to remotely monitor the bacterial levels of rivers and lakes in real time. Additionally, the General Services Administration has begun using sensors to measure and verify the energy efficiency of “green” buildings (PDF), and the Department of Transportation relies on sensors to monitor traffic and control traffic signals and roadways. All of which is productive, but more needs to be done. Read more…

Mesh networking extends IoT reach

A suitable network topology for building automation.

XBee_Series_2_with_Whip_AntennaEditor’s note: this article is part of a series exploring the role of networking in the Internet of Things.

Today we are going to consider the attributes of wireless mesh networking, particularly in the context of our building monitoring and energy application.

A host of new mesh networking technologies came upon the scene in the mid-2000s through start-up ventures such as Millennial Net, Ember, Dust Networks, and others. The mesh network topology is ideally suited to provide broad area coverage for low-power, low-data rate applications found in application areas like industrial automation, home and commercial building automation, medical monitoring, and agriculture.
