- Meshlab — open source, portable, and extensible system for the processing and editing of unstructured 3D triangular meshes.
- HTML5 Video on iOS (Steve Souders) — While it’s true that Mobile Safari on iOS doesn’t buffer any video data as a result of the PRELOAD attribute, it does make other video requests that aren’t counted as “buffered” video. The number and size of the requests and responses depends on the video. For larger videos the total amount of data for these behind-the-scenes requests can be significant.
- Space Monkey (Kickstarter) — distributed encrypted peer-to-peer cloud service using custom hardware. Not open source, which would make me nervous that I was buying a botnet client with storage capability. (via BERG London)
- Matasano Crypto Challenges — Counting is not a hard problem. But cryptography is. There are just a few things you can screw up to get the size of a buffer wrong. There are tens, probably hundreds, of obscure little things you can do to take a cryptosystem that should be secure even against an adversary with more CPU cores than there are atoms in the solar system, and make it solveable with a Perl script and 15 seconds. Don’t take our word for it: do the challenges and you’ll see. People “know” this already, but they don’t really know it in their gut, and we think the reason for that is that very few people actually know how to implement the best-known attacks. So, mail us, and we’ll give you a tour of them.

Email Triage, Pulse Detection, Big Building Data, and Raspberryduino Ardpi
- Triage — iPhone app to quickly triage your email in your downtime. See also the backstory. Awesome UI.
- Webcam Pulse Detector — I was wondering how long it would take someone to do the Eulerian video magnification in real code. Now I’m wondering how long it will take the patent-inspired takedown…
- How Microsoft Quietly Built the City of the Future — The team now collects 500 million data transactions every 24 hours, and the smart buildings software presents engineers with prioritized lists of misbehaving equipment. Algorithms can balance out the cost of a fix in terms of money and energy being wasted with other factors such as how much impact fixing it will have on employees who work in that building. Because of that kind of analysis, a lower-cost problem in a research lab with critical operations may rank higher priority-wise than a higher-cost fix that directly affects few. Almost half of the issues the system identifies can be corrected in under a minute, Smith says.
- UDOO (Kickstarter) — mini PC that could run either Android or Linux, with an Arduino-compatible board embedded. Like faster Raspberry Pi but with Arduino Due-compatible I/O.
Video Magnification Code, Copyright MOOC, Open Access Cost-Effectiveness, and SCADA Security (Sucks)
- Eulerian Video Magnification — papers and the MatLab source code for that amazing effect of exaggerating small changes in file. (*This work is patent pending)
- CopyrightX — MOOC on current law of copyright and the ongoing debates concerning how that law should be reformed. Through a combination of pre-recorded lectures, live webcasts, and weekly online seminars, participants in the course will examine and assess the ways in which law seeks to stimulate and regulate creative expression. (via BoingBoing)
- Cost Effectiveness for Open Access Journals — This plot reveals the prestige (Article Influence score) and publication charges for open access journals.
- Results of SANS SCADA Survey 2013 (PDF) — Unfortunately, at this time they seem unable to monitor the PLCs, terminal units and connections to field equipment due to lack of native security in the control systems themselves. (via InfoSecIsland)
Video Effects, Old School, Data Set, and Games Numbers
- Atkinson Dithering in Real Time — a Processing app that renders what the video camera sees, as though it were an original Mac black and white image.
- Patching Binaries — a patch for a crashing bug during import of account transactions or when changing a payee of a downloaded transaction in Microsoft Money Sunset Deluxe. Written with no source, simply by debugging the executable as it shipped for XP.
- Book Crossing Dataset — Contains 278,858 users (anonymized but with demographic information) providing 1,149,780 ratings (explicit / implicit) about 271,379 books.
- Network Games Market Update (Cartagena Capital) — The myth that players use mobile only ‘on the go’ has been shattered. Smartphones and tablets are now mainstream gaming platforms in their own right and a significant proportion of players play in stationary use case scenarios. Stats abound, including 38% of tablet gamers play more than five hours per week compared to 20% of mobile phone gamer.
Explore Your World, Cyberwar Cyberon, The Paperlessless Society, and Video Hackery
- 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.
- 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.”
- 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.
- Magnifying Temporal Variation in Video — Our 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)
Benefits of a Velocity diet, data journalism's history, it's evolution time for booksellers.
This week on O'Reilly: We learned how the Velocity Conference site got a big makeover thanks to Velocity practices, Liliana Bounegru offered a brief history of data journalism, and Joe Wikert explained how booksellers can reinvent themselves.
- Tupac Coachella Behind the Technology (CBS) — interesting to me is Dr. Dre and Snoop Dogg were considering taking Shakur with them on tour. Just as Hobbit, Tintin, etc. are CG-ing characters to look normal, is the future of “live” spectacle to be this kind of CG show? Will new acts be competing against the Rolling Stones forever?
- wkhtmltopdf (Google Code) — Simple shell utility to convert html to pdf using the webkit rendering engine, and qt. My first piece of “I wrote this, now you can use it too” open source was an HTML to PS converter (this was 1994 or so) via LaTeX. It’s a useful thing, no really.
- Nicira (Wired) — moving network management into software so the network hardware is as dumb as possible. Interesting continuation of the End-to-End principle, whereby smarts live at the edges of the network and the conduits are dumb.
What to watch for in HTML5, CSS, and the open web.
HTML5 author Christopher Schmitt talks with O'Reilly editor Simon St. Laurent about why it's a great time to be a web developer.
jQuery Video Plugin, Open Source Data View, QR Insanity, and Measuring Citizen Science
- jPlayer — jQuery plugin for audio and video in HTML5. Dual-licensed MIT and GPL.
- QR Code Madness — I recently received an MMS (multimedia text message) with a picture to a QR code. First, it’s bad enough advertising agencies still randomly text people ads. Second, what am I supposed to scan that with? My eyes? But check out the photo for maximum silliness.
- Galaxy Zoo: Crowdsourcing Citizen Scientists (Guardian) — yes, the headline is a collection of buzzwords but the Galaxy Zoo project remains fantastic. My eye was caught by Working 12 hours a day non-stop for a week, [Kevin] Schawinski had managed the not inconsiderable task of detailing the characteristics of 50,000 galaxies. He needed a pint. [... they built Galaxy Zoo in a day of two ...] Within 24 hours of it being announced on Lintott’s website, Galaxy Zoo was receiving 70,000 classifications an hour. They still measure their hit-rate in “Kevin weeks” – a unit of 50,000. “Soon after that we were doing many Kevin weeks per hour,” Schawinski says. (via Roger Dennis)
