SCADA Security, Graph Clustering, Facebook Flipbook, and Projections Illustrated

  1. Hackers Gain ‘Full Control’ of Critical SCADA Systems (IT News) — The vulnerabilities were discovered by Russian researchers who over the last year probed popular and high-end ICS and supervisory control and data acquisition (SCADA) systems used to control everything from home solar panel installations to critical national infrastructure. More on the Botnet of Things.
  2. mclMarkov Cluster Algorithm, a fast and scalable unsupervised cluster algorithm for graphs (also known as networks) based on simulation of (stochastic) flow in graphs.
  3. Facebook to Launch Flipboard-like Reader (Recode) — what I’d actually like to see is Facebook join the open web by producing and consuming RSS/Atom/anything feeds, but that’s a long shot. I fear it’ll either limit you to whatever circle-jerk-of-prosperity paywall-penetrating content-for-advertising-eyeballs trades the Facebook execs have made, or else it’ll be a leech on the scrotum of the open web by consuming RSS without producing it. I’m all out of respect for empire-builders who think you’re a fool if you value the open web. AOL might have died, but its vision of content kings running the network is alive and well in the hands of Facebook and Google. I’ll gladly post about the actual product launch if it is neither partnership eyeball-abuse nor parasitism.
  4. Map Projections Illustrated with a Face (Flowing Data) — really neat, wish I’d had these when I was getting my head around map projections.

Arduino Robot, LIDAR for Phones, Climbing Bots, and OS X Emulators

  1. Arduino Robot — for all your hacking needs.
  2. LIDAR for Smartphones (DIYdrones) — The device attaches to the back of a smartphone and combines a built-in laser range finder, 3D compass and Bluetooth chip with the phone’s camera and GPS.
  3. Bridge Inspection Robot Equipping Magnets — 7.8 inches/second, magnets, can scuttle up walls and along ceilings.
  4. OpenEmu — nice-looking emulator framework for OS X. Make your Christmas present a trip back in time.

Disruption, Telepresence, Drone Mapping, and TV Malware

  1. Innovation and the Coming Shape of Social Transformation (Techonomy) — great interview with Tim O’Reilly and Max Levchin. in electronics and in our devices, we’re getting more and more a sense of how to fix things, where they break. And yet as a culture, what we have chosen to do is to make those devices more disposable, not last forever. And why do you think it will be different with people? To me one of the real risks is, yes, we get this technology of life extension, and it’s reserved for a very few, very rich people, and everybody else becomes more disposable.
  2. Attending a Conference via a Telepresence Robot (IEEE) — interesting idea, and I look forward to giving it a try. The mark of success for the idea, alas, is two bots facing each other having a conversation.
  3. Drone Imagery for OpenStreetMap — 100 acres of 4cm/pixel imagery, in less than an hour.
  4. LG Smart TV Phones Home with Shows and Played Files — welcome to the Internet of Manufacturer Malware.

Rich Text Editing, Structural Visualisation, DDoS Protection, Realtime DDoS Map

  1. Sir Trevor — nice rich-text editing. Interesting how Markdown has become the way to store formatted text without storing HTML (and thus exposing the CSRF-inducing HTML-escaping stuckfastrophe).
  2. Slate for Excel — visualising spreadsheet structure. I’d be surprised if it took MSFT or Goog 30 days to acquire them.
  3. Project Shield — Google project to protect against DDoSes.
  4. Digital Attack Map — DDoS attacks going on around the world. (via Jim Stogdill)

Camera Heart Rate, Low Power Location, Quantified Self Radio, and a Multi Sensor

  1. Measuring Heart Rate with a Smartphone Camera — not yet realtime, but promising sensor development.
  2. iBeaconslow-power, short-distance location monitoring beacons. Any iOS device that supports Bluetooth Low Energy can become an iBeacon, and can detect other iBeacons when they are nearby. Apps can be notified when iBeacons move in and out of range of the device, and can monitor the proximity of iBeacons as their proximity changes over time.
  3. Analysis: The Quantified Self (BBC) — radio show on QS. Good introduction for the novice.
  4. Tinke — heart rate, blood oxygen, respiration rate, and heart rate variability in a single small sensor that plugs into your iOS device.

Spatial Verbs, Open Source Malaria, Surviving Management, and Paper-like UAV

  1. Operative Design — A catalogue of spatial verbs. (via Adafruit)
  2. Open Source Malaria — open science drug discovery.
  3. Surviving Being (Senior) Tech Management (Kellan Elliott-McCrea) — Perspective is the thin line between a challenging but manageable problem, and chittering balled up in the corner.
  4. Disposable UAVs Inspired by Paper Planes (DIY Drones) — The first design, modeled after a paper plane, is created from a cellulose sheet that has electronic circuits ink-jet printed directly onto its body. Once the circuits have been laid on the plane’s frame, the craft is exposed to a UV curing process, turning the planes body into a flexible circuit board. These circuits are then connected to the planes “avionics system”, two elevons attached to the rear of the craft, which give the UAV the ability to steer itself to its destination.

History as Science, Indoor Location, Nightscape Photography, and Finding the Impossible

  1. Cliodynamics: History as Sciencea systematic application of the scientific method to history: verbal theories should be translated into mathematical models, precise predictions derived, and then rigorously tested on empirical material. In short, history needs to become an analytical, predictive science.
  2. Cricket — indoor location system from MIT. In a nutshell, Cricket uses a combination of RF and ultrasound technologies to provide location information to attached host devices. Wall- and ceiling-mounted beacons placed through a building publish information on an RF channel. […] The listener runs algorithms that correlate RF and ultrasound samples (the latter are simple pulses with no data encoded on them) and to pick the best correlation. Even in the presence of several competing beacon transmissions, Cricket achieves good precision and accuracy quickly.
  3. The World at Nightan international effort to present stunning nightscape photos and time-lapse videos of the world’s landmarks against celestial attractions.
  4. Paul Steinhardt on Impossible Crystals (YouTube) — quasi-crystals with five-fold symmetry previously believed impossible. And then he found one, and led an expedition in 2011 to Chukotka in Far Eastern Russia to find new information about its origin and search for more samples. As you do when you’re the Albert Einstein Professor of Science at Princeton, a job title that comes with no pressure at all to bring home the impossible.

Location Data, Online Science, Mythbusting for Education, and Cheap Music For All

  1. Reading Runes in Animal Movement (YouTube) — accessible TEDxRiverTawe 2013 talk by Professor Rory Wilson, on his work tracking movements of animals in time and space. The value comes from high-resolution time series data: many samples/second, very granular.
  2. Best Science Writing Online 2012 (Amazon) — edited collection of the best blog posts on science from 2012. Some very good science writing happening online.
  3. Designing Effective Multimedia for Physics Education (PDF) — Derek Muller’s PhD thesis, summarised as “mythbusting beats lectures, hands down”. See also his TED@Sydney talk.
  4. Melomics — royalty-free computer-generated music, all genres, for sale (genius business model). Academic spinoff from Dr. Francisco J. Vico’s work at UMA in Spain.

Thread Problems, Better Image Search, Open Standards, and GitHub Maps

  1. Multithreading is HardThe compiler and the processor both conspire to defeat your threads by moving your code around! Be warned and wary! You will have to do battle with both. Sample code and explanation of WTF the eieio barrier is (hint: nothing to do with Old McDonald’s server farm). (via Erik Michaels-Ober)
  2. Improving Photo Search (Google Research) — volume of training images, number of CPU cores, and Freebase entities. (via Alex Dong)
  3. Is Google Dumping Open Standards for Open Wallets? (Matt Asay) — it’s easier to ship than standardise, to innovate than integrate, but the ux of a citizen in the real world is pants. Like blog posts? Log into Facebook to read your friends! (or Google+) Chat is great, but you’d better have one client per corporation your friends hang out on. Nobody woke up this morning asking for features to make web pages only work on one browser. The user experience of isolationism is ugly.
  4. GitHub Renders GeoJSONUnder the hood we use Leaflet.js to render the geoJSON data, and overlay it on a custom version of MapBox’s street view baselayer — simplified so that your data can really shine. Best of all, the base map uses OpenStreetMap data, so if you find an area to improve, edit away.
