Deblurring Images, Games Design, Secure Control, and Faster Emulation

  1. Restoration of Defocused and Blurry Images — impressive demos, and open source (GPLv3) code. All those blurred faces and documents no longer seem so safe.
  2. Peter Molyneux Profile in Wired — worth reading for: (a) Molyneux’s contribution to the genre; (b) the inspiration he drew from his satirical Twitter mirror (@PeterMolydeux) is lovely, and (c) the game jams to build the fake Molyneux games, where satire becomes reality. (via Andy Baio)
  3. Trusted Computing for Industrial Control Systems — Kaspersky reveals plans for an open source O/S for industrial control systems, so reactors and power stations and traffic systems aren’t vulnerable to StuxNet-type attacks. (via Jim Stogdill)
  4. Android Virtual Machines — faster emulation for testing than the traditional simulators.

Crowdsourcing Flights, Teaching Programming, Redeploying Finance Engineers, and Recognising Cat Faces

  1. FlightfoxReal people compete to find you the best flights. Crowdsourcing beating algorithms …. (via NY Times)
  2. Code Monster (Crunchzilla) — a fun site for parents to learn to program with their kids. Loving seeing so much activity around teaching kids to program. (via Greg Linden)
  3. Telling People to Leave Finance (Cathy O’Neil) — There’s an army of engineers in finance that could be putting their skills to use with actual innovation rather than so-called financial innovation.
  4. Kittydar (GitHub) — cat face recognition in Javascript.

Aaron Swartz, Baghdad Makerspace, Teaching in Africa, and Ephemeral People

  1. Aaron Swartz Defense Fund — American computer systems are under attack every day of the week from foreign governments, and the idiot prosecutor is wasting resources doubling down on this vindictive nonsense.
  2. Baghdad Community Hackerspace Workshops (Kickstarter) — Makerspace in Baghdad, built by people who know how to do this stuff in that country. (via BoingBoing)
  3. Teaching Web Development in AfricaI used the resources that Pamela Fox helpfully compiled at teaching-materials.org to mentor twelve students who all built their own websites, such as websites for their karate club, fashion club, and traditional dance troupe. One student made a website to teach others about the hardware components of computers, and another website discussing the merits of a common currency in the East African Community. The two most advanced students began programming their own computer game to help others practice touch typing, and it allows players to compete across the network with WebSockets.
  4. Transient Faces (Jeff Howard) — only displaying the unchanging parts of a scene, effectively removing people using computer vision. Disconcerting and elegant. (via Greg Borenstein)

Reproducibility, Open Projects, Disposable Forums, and Prosthetic Retina

  1. Reproducibility Initiative (Science Exchange) — a service offering researchers who will attempt to reproduce your work. Validated studies will receive a Certificate of Reproducibility acknowledging that their results have been independently reproduced as part of the Reproducibility Initiative. Researchers have the opportunity to publish the replicated results as an independent publication in the PLOS Reproducibility Collection, and can share their data via the figshare Reproducibility Collection repository. The original study will also be acknowledged as independently reproduced if published in a supporting journal. See also writeup in Nature.
  2. Designing Open Projects (PDF) — IBM report with very sensible advice on steps to take when creating open projects for engagement and participation. Should be recommended reading for all who hope to get others to help.
  3. Hustleboards — “disposable forums”, easy lightweight web-based chats. Nice and simple UI.
  4. Prosthetic Retina Helps Restore Sight in Mice (Nature) — computer-mediated vision won’t change our world, but it’ll change what we think is in our world.

CV Camouflage, Best Practices, Failure Conference, and Fiber Lessons

  1. Urban Camouflage WorkshopMost of the day was spent crafting urban camouflage intended to hide the wearer from the Kinect computer vision system. By the end of the workshop we understood how to dress to avoid detection for the three different Kinect formats. (via Beta Knowledge)
  2. Starting a Django Project The Right Way (Jeff Knupp) — I wish more people did this: it’s not enough to learn syntax these days. Projects live in a web of best practices for source code management, deployment, testing, and migrations.
  3. FailCona one-day conference for technology entrepreneurs, investors, developers and designers to study their own and others’ failures and prepare for success. Figure out how to learn from failures—they’re far more common than successes. (via Krissy Mo)
  4. Google Fiber in the Real World (Giga Om) — These tests show one of the limitations of Google’s Fiber network: other services. Since Google Fiber is providing virtually unheard of speeds for their subscribers, companies like Apple and I suspect Hulu, Netflix and Amazon will need to keep up. Are you serving DSL speeds to fiber customers? (via Jonathan Brewer)

Chinese Hackers, Edible Sensors, Quantum Physics

  1. China Hackers Hit EU Point Man and DC (Bloomberg) — wow. The extent to which EU and US government and business computer systems have been penetrated is astonishing. Stolen information is flowing out of the networks of law firms, investment banks, oil companies, drug makers, and high technology manufacturers in such significant quantities that intelligence officials now say it could cause long-term harm to U.S. and European economies. (via Gady Epstein)
  2. Digestible Microchips (Nature) — The sand-particle sized sensor consists of a minute silicon chip containing trace amounts of magnesium and copper. When swallowed, it generates a slight voltage in response to digestive juices, which conveys a signal to the surface of a person’s skin where a patch then relays the information to a mobile phone belonging to a healthcare-provider. (via Sara Winge)
  3. Quantum Mechanics Make Simple(r) — clever way to avoid the brain pain of quantum mechanics and leap straight to the “oh!”. [N]ature is described not by probabilities (which are always nonnegative), but by numbers called amplitudes that can be positive, negative, or even complex. [...] In the usual “hierarchy of sciences”—with biology at the top, then chemistry, then physics, then math—quantum mechanics sits at a level between math and physics that I don’t know a good name for. Basically, quantum mechanics is the operating system that other physical theories run on as application software (with the exception of general relativity, which hasn’t yet been successfully ported to this particular OS). (via Hacker News)
  4. Selectively De-Animating Video — SIGGRAPH talk showing how to keep some things still in a video. Check out the teaser video with samples: ZOMG. I note that Maneesh Agrawala was involved: I’m a fan of his from Line Drive maps and 3D exploded views, but his entire paper list is worth reading. Wow. (via Greg Borenstein)

No Augmenting Money, Cat CV, Quantified Mind, and Hackable Bio

  1. Bank of England Complains About AR Bank NotesAfter downloading the free Blippar app on iPhone or Android, customers were able to ‘blipp’ any ten-pound note in circulation by opening the app and holding their phone over the note. An animated Queen, and other members of the Royal Family, then appeared on the screen and voiced opinions on the latest football matters.
  2. Kittydar — open source computer vision library in Javascript for identifying cat faces. I am not making this up. (via Kyle McDonald
  3. Quantified Mind — battery of cognitive tests, so you can track performance over time and measure the effect of interventions (coffee, diet, exercise, whatever). (via Sara Winge)
  4. Jellyfish Made From Rat Cells (Nature) — an artificial jellyfish using silicone and muscle cells from a rat’s heart. The synthetic creature, dubbed a medusoid, looks like a flower with eight petals. When placed in an electric field, it pulses and swims exactly like its living counterpart. Very cool, but the bit that caught my eye was: the team built the medusoid as a way of understanding the “fundamental laws of muscular pumps”. It is an engineer’s approach to basic science: prove that you have identified the right principles by building something with them.

Turing Talk, Table Editor, Posture Sensor, and Cheating 'Bot

  1. Turing Centenary Speech (Bruce Sterling) — so many thoughtbombs, this repays rereading. We’re okay with certain people who “think different” to the extent of buying Apple iPads. We’re rather hostile toward people who “think so very differently” that their work will make no sense for thirty years — if ever. We’ll test them, and see if we can find some way to get them to generate wealth for us, but we’re not considerate of them as unusual, troubled entities wandering sideways through a world they never made.Cognition exists, and computation exists, but they’re not the same phenomenon with two different masks on.Explain to me, as an engineer, why it’s so important to aspire to build systems with “Artificial Intelligence,” and yet you’d scorn to build “Artificial Femininity.” What is that about?Every day I face all these unstable heaps of creative machinery. How do we judge art created with, by, and or through these devices? What is our proper role with them? [...] How do we judge what we’re doing? How do we distribute praise and blame, rewards and demerits, how do to guide it, how do we attribute meaning to it? … oh just read the whole damn piece, it’s the best thing you’ll read this month.
  2. Handsontable — Excel-like grid editing plugin for jQuery (MIT-licensed).
  3. Lumoback (Kickstarter) — smart posture sensor which provides a gentle vibration when you slouch to remind you to sit or stand straight. It is worn on your lower back and designed to be slim, sleek and so comfortable that you barely feel it when you have it on. (via Tim O’Reilly)
  4. Robot Hand Beats You At Rock-Paper-Scissors (IEEE) — tl;dr: computer vision and fast robotics means it chooses after you reveal, but it happens so quickly that you don’t realize it’s cheating. (via Hacker News)

Post-Capture Zoom, Load Gen, Inventive Malware, and Manufactured Normalcy

  1. SnapItHD — camera captures full 360-degree panorama and users select and zoom regions afterward. (via Idealog)
  2. Iago (GitHub) — Twitter’s load-generation tool.
  3. AutoCAD Worm Stealing Blueprints — lovely, malware that targets inventions. The worm, known as ACAD/Medre.A, is spreading through infected AutoCAD templates and is sending tens of thousands of stolen documents to email addresses in China. This one has soured, but give the field time … anything that can be stolen digitally, will be. (via Slashdot)
  4. Designing For and Against the Manufactured Normalcy Field (Greg Borenstein) — Tim said this was one of his favourite sessions at this year’s Foo Camp: breaking the artificial normality than we try to cast over new experiences so as to make them safe and comfortable.

Explore Your World, Cyberwar Cyberon, The Paperlessless Society, and Video Hackery

  1. How To Be An Explorer of the World (Amazon) — I want to take this course on design anthropology but this book, the assigned text, looks like an excellent second best.
  2. StuxNet Was American-Made Cyberwarfare Tool (NY Times) — not even the air gap worked for Iran, “It turns out there is always an idiot around who doesn’t think much about the thumb drive in their hand.”
  3. So Much For The Paperless Society (Beta Knowledge Tumblr) — graph of the waxing and waning use of bond paper in North America. Spoiler: we’re still using a lot.
  4. Magnifying Temporal Variation in VideoOur goal is to reveal temporal variations in videos that are difficult or impossible to see with the naked eye and display them in an indicative manner. Our method, which we call Eulerian Video Magnification, takes a standard video sequence as input, and applies spatial decomposition, followed by temporal filtering to the frames. The resulting signal is then amplified to reveal hidden information. Using our method, we are able to visualize the flow of blood as it fills the face and also to amplify and reveal small motions. Our technique can run in real time to show phenomena occurring at temporal frequencies selected by the user. This is amazing: track the pulse in your face from a few frames. (via Hacker News)
