Demythologizing Big Data, Online Scams, A Useful Computer Vision Library, and Opening Politics
- The Mythology of Big Data (PDF) — slides from a Strata keynote by Mark R. Madsen. A lovely explanation of the social impediments to the rational use of data. (via Hamish MacEwan)
- Scamworld — amazing deconstruction of the online “get rich quick” scam business. (via Andy Baio)
- Ceres: Solving Complex Problems with Computing Muscle — Johnny Lee Chung explains the (computer vision) uses of the open source Ceres Non-Linear Least Squares Solver library from Google.
- How to Start a Think Tank (Guardian) — The answer to the looming crisis of legitimacy we’re facing is greater openness – not just regarding who met who at what Christmas party, but on the substance of policy. The best way to re-engage people in politics is to change how politics works – in the case of our project, to develop a more direct way for the people who use and provide public and voluntary services to create better social policy. Hear, hear. People seize on the little stuff because you haven’t given them a way to focus something big with you.
Aussies Dump Huawei, History of Information, Corner Vision, and Questioning Higher Ed Effectiveness
- Australian NSA Forces National Broadband Network to Dump Huawei — Australia’s government security organization knocked Huawei out of the eligible bidding list. “It’s the exact area where we have been the sole supplier in the United Kingdom for the past six years,” Huawei’s director of corporate and public affairs, Jeremy Mitchell, told the Financial Review. Governments ask themselves how to be assured of information security when routers, firewalls, etc. are made in countries that have fostered attacks against other states and corporations.
- From Cave Paintings to the Internet — a timeline of many (many) milestones in the history of information.
- How to See Around Corners (Nature) — love the production of the demo video, but interesting to see how computation is becoming integral to vision apps. (via Ed Yong)
- Are Undergraduates Actually Learning Anything? (Chronicle of Higher Ed) — Growing numbers of students are sent to college at increasingly higher costs, but for a large proportion of them the gains in critical thinking, complex reasoning, and written communication are either exceedingly small or empirically nonexistent. At least 45 percent of students in our sample did not demonstrate any statistically significant improvement in Collegiate Learning Assessment [CLA] performance during the first two years of college. [Further study has indicated that 36 percent of students did not show any significant improvement over four years.] Why your graduate intake feels disappointing: it is. (via Counterpunch)
Squirrel Targeting with Computer Vision, Audio Recognition, Single Page Apps, and Persisting at Failing
- Militarizing Your Backyard With Python and Computer Vision (video) — using a water cannon, computer video, Arduino, and Python to keep marauding squirrel hordes under control. See the finished result for Yakkity Saxed moist rodent goodness.
- Soundbite — dialogue search for Apple’s Final Cut Pro and Adobe Premiere Pro. Boris Soundbite quickly and accurately finds any word or phrase spoken in recorded media. Shoot squirrels with computer vision, search audio with computer hearing. We live in the future, people. (via Andy Baio)
- Why Finish Books? (NY Review of Books) — the more bad books you finish, the fewer good ones you”ll have time to start. Applying this to the rest of life is left as an exercise for the reader.
Android Fragmentation, Hosting Technologies, Face Recognition, and Data Design
- Fragmentation is Not The End of Android — full of trenchant insights, this post considers the many implications of the Android value chain. Only Apple directly profits from being an OS provider in the mobile ecosystem. For Google it is a cost center particularly struck me. Anyone know whether Google offers to (for money) maintain branded carrier- and/or device-specific versions of Android? Seems like a natural business model given their development pipeline and desire to ensure availability of updates. (via John Gruber)
- Chart of Y Combinator Companies’ Hosting Decisions — just what it says.
- Muststache — fun Chrome extension using face recognition to add mustaches to faces in pictures. Ten years ago, almost every kind of face recognition was a dark art requiring many computrons. Today it’s a toy.
- Stamen’s 2011 — frankly astonishing year of beautiful and meaningful visualizations and design. They continue to provide the benchmarks for designing with data.
Smart Meter Snitches, Company Culture, Text Classification, and Live Face Substitution
- Smart Hacking for Privacy — can mine smart power meter data (or even snoop it) to learn what’s on the TV. Wow. (You can also watch the talk). (via Rob Inskeep)
- Conditioning Company Culture (Bryce Roberts) — a short read but thought-provoking. It’s easy to create mindless mantras, but I’ve seen the technique that Bryce describes and (when done well) it’s highly effective.
- hydrat (Google Code) — a declarative framework for text classification tasks.
- Dynamic Face Substitution (FlowingData) — Kyle McDonald and Arturo Castro play around with a face tracker and color interpolation to replace their own faces, in real-time, with celebrities such as that of Brad Pitt and Paris Hilton. Awesome. And creepy. Amen.
- See the World as a Colour-Blind Person Would — filters that let you see images as protanopes, deuteranopes, and even tritanopes would see them. I am protanoptic (if that’s a word) and I can vouch that the “after” pix look the same as “before” to me. Care, because about 8% of men have some form of colourblindness and hate you and your “red is bad, green is good” visual cues. (via Flowing Data)
- Waffles — seeks to be the world’s most comprehensive collection of command-line tools for machine learning and data mining.
- LinkedIn Open Sources Index and Query Services — full-text index and retrieval engine, APIs, and a framework to manage indexes on infrastructure-as-a-service.
Inside-Out Libraries, Cleaner YouTube, Kid Tablet, Facetracking Toy
- Massive Wikimedia Donation — I missed it when it happened, but the State Library of Queensland made the 4th largest ever donation of high-resolution out-of-copyright images to the Wikimedia Foundation. The image metadata are available through Wikimedia under liberal licensing terms, too. This is what your national and state libraries should be doing!
- Clea.nr — strip all the crap from around YouTube pages. (via Ed Tech Ideas)
- Nabi Tablet (Toys R Us) — ruggedized Android tablet for kids, $199 price point. (via Mark Osborne)
- Face-Tracking KiddyZoom Video Cam (YouTube) — I’m always startled most when the future turns up in kids’ toys. Tablets and face-tracking? Soon it’ll be face recognition (“hello mommy!” says the doll), brainwave-triggered activity, and 3D printers. (via BERG London)
Coaching, Geospatial Tracking, Eye-Tracking, and Networked Objects
- Personal Best (New Yorker) — excellent Atul Gawande column on coaching which has me wondering how to open up different aspects of my life to improvement. Interesting to me because, behind every continuous- or self-improvement technique are the questions: “do you want to get better?” and “if so, how far will you go in pursuit of that goal?”.
- CyberTracker — tool for non-profits tracking things in the real world. Used around the world for ecology, disaster recovery, even crime-fighting. Brings geospatial data capture and analytics to environmental orgs who otherwise could never afford it.
- Eye-Tracking in Painting Restoration — The consequence of the different gaze pattern is that when asked to describe the content of the painting, viewers of the unreconstructed version did not realise it was a painting of an erupting volcano. The painting had lost its meaning and viewers could not view it as originally intended by Martin. (via Ed Yong)
- The Era of Objects (PDF) — a collection of essays around the future of networked objects, from a Blowup event on that topic. Writings from Bruce Sterling, Julian Bleecker, and others.
Telco-less Mobile Calls, Videogames, Open Source Hardware, Facial Recognition
- Viber — more and more people are wanting to talk to me via this, rather than Skype or direct phone call (req. wifi). Can’t tell whether massive disruptor or toy.
- Who Killed Videogames — “The players will come for the cute characters, and stay for the cruel mathematics.”
- Visual Diffs for Open Source Hardware — just what it says.
- Facebook Face Recognition Study — take profile photos from dating sites, facial-recognition match against Facebook photos to find identity, use to predict interests and social security numbers.
