- Visually Programming Arduino — good for little minds.
- Rapid Hardware Iteration at Scale (Forbes) — It’s part of the unique way that Xiaomi operates, closely analyzing the user feedback it gets on its smartphones and following the suggestions it likes for the next batch of 100,000 phones. It releases them every Tuesday at noon Beijing time.
- Machine Learning of Hierarchical Clustering to Segment 2D and 3D Images (PLoS One) — We propose an active learning approach for performing hierarchical agglomerative segmentation from superpixels. Our method combines multiple features at all scales of the agglomerative process, works for data with an arbitrary number of dimensions, and scales to very large datasets.
- Kratu — an Open Source client-side analysis framework to create simple yet powerful renditions of data. It allows you to dynamically adjust your view of the data to highlight issues, opportunities and correlations in the data.

Visual Arduino Coding, Hardware Iteration, Segmenting Images, and Client-Side Adjustable Data View
Rich Text Editing, Structural Visualisation, DDoS Protection, Realtime DDoS Map
- 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).
- Slate for Excel — visualising spreadsheet structure. I’d be surprised if it took MSFT or Goog 30 days to acquire them.
- Project Shield — Google project to protect against DDoSes.
- Digital Attack Map — DDoS attacks going on around the world. (via Jim Stogdill)
Algorithmic Optimisation, 3D Scanners, Corporate Open Source, and Data Dives
- Unhappy Truckers and Other Algorithmic Problems — Even the insides of vans are subjected to a kind of routing algorithm; the next time you get a package, look for a three-letter letter code, like “RDL.” That means “rear door left,” and it is so the driver has to take as few steps as possible to locate the package. (via Sam Minnee)
- Fuel3D: A Sub-$1000 3D Scanner (Kickstarter) — a point-and-shoot 3D imaging system that captures extremely high resolution mesh and color information of objects. Fuel3D is the world’s first 3D scanner to combine pre-calibrated stereo cameras with photometric imaging to capture and process files in seconds.
- Corporate Open Source Anti-Patterns (YouTube) — Brian Cantrill’s talk, slides here. (via Daniel Bachhuber)
- Hacking for Humanity) (The Economist) — Getting PhDs and data specialists to donate their skills to charities is the idea behind the event’s organizer, DataKind UK, an offshoot of the American nonprofit group.
The cities appear to breathe as bicycles move into office districts in the morning and out in the evening.
3D Visualization, Printing On Any Surface, Rebuilding Reality, and Emotions as Data
- For Example — amazing discussion of 3D visualization techniques, full of examples using the D3.js library and bl.ocks.org example gist system. Gorgeous and informative.
- Anti-Gravity 3D Printer — uses strands to sculpt on any surface. (via Slashdot)
- How 3D Printing Will Rebuild Reality (BoingBoing) — But even though home 3D-printing has received substantial publicity of late, it is in the industrial sector where the technology will probably make its most significant near-term impact on the world both by manufacturing improved commercial products and by stimulating industry to develop next-generation fab methods and machines that could one day truly bring 3D-printing home to users in a real way.
- The Emotional Side of Big Data — Personal Democracy Forum 2013 talk by Sara Critchfield, on reframing emotion as data for decision-making. (via Quartz)
It's not the data itself but what you do with it that counts.
Geeky Primer, Visible CSS, Remote Working, and Raspberry Pi Sentiment Server
- My Little Geek — children’s primer with a geeky bent. A is for Android, B is for Binary, C is for Caffeine …. They have a Kickstarter for two sequels: numbers and shapes.
- Visible CSS Rules — Enter a url to see how the css rules interact with that page.
- How to Work Remotely — none of this is rocket science, it’s all true and things we had to learn the hard way.
- Raspberry Pi Twitter Sentiment Server — step-by-step guide, and github repo for the lazy. (via Jason Bell)
New Kinect, Surveillance of Things, How to Criticise, and Compensating for Population
- XBox One Kinect Controller (Guardian) — the new Kinect controller can detect gaze, heartbeat, and the buttons on your shirt.
- Surveillance and the Internet of Things (Bruce Schneier) — Lots has been written about the “Internet of Things” and how it will change society for the better. It’s true that it will make a lot of wonderful things possible, but the “Internet of Things” will also allow for an even greater amount of surveillance than there is today. The Internet of Things gives the governments and corporations that follow our every move something they don’t yet have: eyes and ears.
- Daniel Dennett’s Intuition Pumps (extract) — How to compose a successful critical commentary: 1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it that way.” 2. List any points of agreement (especially if they are not matters of general or widespread agreement). 3. Mention anything you have learned from your target.4. Only then are you permitted to say so much as a word of rebuttal or criticism.
- New Data Science Toolkit Out (Pete Warden) — with population data to let you compensate for population in your heatmaps. No more “gosh, EVERYTHING is more prevalent where there are lots of people!” meaningless charts.
Privacy: Gone in 150ms, Pen-Testing Tablet, Low-Level in Lua, and Metaphor Identification Shootout
- Behind the Banner — visualization of what happens in the 150ms when the cabal of data vultures decide which ad to show you. They pass around your data as enthusiastically as a pipe at a Grateful Dead concert, and you’ve just as much chance of getting it back. (via John Battelle)
- pwnpad — Nexus 7 with Android and Ubuntu, high-gain USB bluetooth, ethernet adapter, and a gorgeous suite of security tools. (via Kyle Young)
- Terra — a simple, statically-typed, compiled language with manual memory management [...] designed from the beginning to interoperate with Lua. Terra functions are first-class Lua values created using the terra keyword. When needed they are JIT-compiled to machine code. (via Hacker News)
- Metaphor Identification in Large Texts Corpora (PLOSone) — The paper presents the most comprehensive study of metaphor identification in terms of scope of metaphorical phrases and annotated corpora size. Algorithms’ performance in identifying linguistic phrases as metaphorical or literal has been compared to human judgment. Overall, the algorithms outperform the state-of-the-art algorithm with 71% precision and 27% averaged improvement in prediction over the base-rate of metaphors in the corpus.
