Eye Catcher (We Make Money Not Art) — the most banal-looking wooden frame takes thus a life of its own as soon as you come near it. It quickly positions itself in front of you, spots your eyes and starts expressing ‘emotions’ based on your own. Eye Catcher uses the arm of an industrial robot, high power magnets, a hidden pinhole camera, ferrofluid and emotion recognition algorithms to explore novel interactive interfaces based on the mimicry and exchange of expressions.

Homebrew Cray-1A – fascinating architecture, but also lovely hobby project to build the homebrew. The lack of Cray software archives horrifies the amateur historian in me, though. When I started building this, I thought “Oh, I’ll just swing by the ol’ Internet and find some groovy 70′s-era software to run on it.” It turns out I was wrong. One of the sad things about pre-internet machines (especially ones that were primarily purchased by 3-letter Government agencies) is that practically no software exists for them. After searching the internet exhaustively, I contacted the Computer History Musuem and they didn’t have any either. They also informed me that apparently SGI destroyed Cray’s old software archives before spinning them off again in the late 90′s.
How Do Committees Invent? — 1968 paper that gave us organizations which design systems [...] produce designs which are copies of the communication structures of these organizations. That was the 1968 version of the modern “your website’s sitemap is your org chart”.
slic3r — converts a digital 3D model into printing instructions for your 3D printer. It cuts the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded.
gCodeViewer — GCode is the “numerical control language” for telling extruders, mills, polishers, etc. where to move to and when. This open source package is a visual GCode visualizer, viewer and analyzer in your own browser! It works on any OS in almost any modern browser (chrome, ff, safari 6, opera, ie10 should work too). All you need to do – is drag your *.gcode file to the designated zone.
AC Power Control with Arduino — in the video video and the code, we take an in depth look at the hardware for using Arduino interrupts to control AC power through a triac. Using a zero-crossing detector Arduino will detect the pulse then calculate a delay to control the power output to a load.
Awesome Pokemon Hack — each inventory item has a number associated with it, they are kept at a particular memory location, and there’s a glitch in the game that executes code at that location so … you can program by assembling items and then triggering the glitch. SO COOL.
Algorithms and Accountability — Thus, the appearance of an autocompletion suggestion during the search process might make people decide to search for this suggestion although they didn’t have the intention to. A recent paper by Baker and Potts (2013) consequently questions “the extent to which such algorithms inadvertently help to perpetuate negative stereotypes”. (via New Aesthetic Tumblr)

Repacking Lego Batteries with a CNC Mill — check out the video. Patrick programmed a CNC machine to drill out the rivets holding the Mindstorms battery pack together. Coding away a repetitive task like this is gorgeous to see at every scale. We don’t have to teach our kids a particular programming language, but they should know how to automate cruft.
My Thoughts on Google+ (YouTube) — when your fans make hatey videos like this one protesting Google putting the pig of Google Plus onto the lipstick that was YouTube, you are Doin’ It Wrong.
How Things Work: Summer Games Edition — admire the real craftsmanship in those early games. This has a great description of using raster interrupts to extend the number of sprites, and how and why double-buffering was expensive in terms of memory.
IAMA: Etsy Ops Team (Reddit) — the Etsy ops team does an IAMA on Reddit. Everything from uptime to this sage advice about fluid data: A nice 18 year old Glenfiddich scales extremely well, especially if used in an active active configuration with a glass in each hand. The part of Scotland where Glenfiddich is located also benefits from near-permanent exposure to the Cloud (several clouds in fact). (via Nelson Minar)
Why YouTube Buffers (ArsTechnica) — When asked if ISPs are degrading Netflix and YouTube traffic to steer users toward their own video services, Crawford told Ars that “the very powerful eyeball networks in the US (and particularly Comcast and Time Warner Cable) have ample incentive and ability to protect the IP services in which they have economic interests. Their real goal, however, is simpler and richer. They have enormous incentives to build a moat around their high-speed data networks and charge for entry because data is a very high-margin (north of 95 percent for the cable companies), addictive, utility product over which they have local monopoly control. They have told Wall Street they will do this. Yes, charging for entry serves the same purposes as discrimination in favor of their own VOD [video-on-demand], but it is a richer and blunter proposition for them.”
Ink — MIT-licensed interface kit for quick development of web interfaces, simple to use and expand on.
Licensing in a Post-Copyright World — This article is opening up a bit of the history of Open Source software licensing, how it seems to change and what we could do to improve it. Caught my eye: Oracle that relicensed Berkeley DB from BSD to APGLv3 [... effectively changing] the effective license for 106 other packages to AGPLv3 as well.
Life Without Sleep — interesting critique of Provigil as performance-enhancing drug for information workers. It is very difficult to design a stimulant that offers focus without tunnelling – that is, without losing the ability to relate well to one’s wider environment and therefore make socially nuanced decisions. Irritability and impatience grate on team dynamics and social skills, but such nuances are usually missed in drug studies, where they are usually treated as unreliable self-reported data. These problems were largely ignored in the early enthusiasm for drug-based ways to reduce sleep. [...] Volunteers on the stimulant modafinil omitted these feedback requests, instead providing brusque, non-question instructions, such as: ‘Exit West at the roundabout, then turn left at the park.’ Their dialogues were shorter and they produced less accurate maps than control volunteers. What is more, modafinil causes an overestimation of one’s own performance: those individuals on modafinil not only performed worse, but were less likely to notice that they did. (via Dave Pell)
Housing Simulator — NZ’s largest city is consulting on its growth plan, and includes a simulator so you can decide where the growth to house the hundreds of thousands of predicted residents will come from. Reminds me of NPR’s Budget Hero. Notice that none of the levers control immigration or city taxes to make different cities attractive or unattractive. Growth is a given and you’re left trying to figure out which green fields to pave.
Converting To and From Google Map Tile Coordinates in PostGIS (Pete Warden) — Google Maps’ system of power-of-two tiles has become a defacto standard, widely used by all sorts of web mapping software. I’ve found it handy to use as a caching scheme for our data, but the PostGIS calls to use it were getting pretty messy, so I wrapped them up in a few functions.Code on github.
So You Want to Build A Connected Sensor Device? (Google Doc) — The purpose of this document is to provide an overview of infrastructure, options, and tradeoffs for the parts of the data ecosystem that deal with generating, storing, transmitting, and sharing data. In addition to providing an overview, the goal is to learn what the pain points are, so we can address them. This is a collaborative document drafted for the purpose of discussion and contribution at Sensored Meetup #10. (via Rachel Kalmar)
What Tim Berners-Lee Doesn’t Know About HTML DRM (Guardian) — Cory Doctorow lays it out straight. HTML DRM is a bad idea, no two ways. The future of the Web is the future of the world, because everything we do today involves the net and everything we’ll do tomorrow will require it. Now it proposes to sell out that trust, on the grounds that Big Content will lock up its “content” in Flash if it doesn’t get a veto over Web-innovation. [...] The W3C has a duty to send the DRM-peddlers packing, just as the US courts did in the case of digital TV.
What Teens Get About The Internet That Parents Don’t (The Atlantic) — the Internet has been a lifeline for self-directed learning and connection to peers. In our research, we found that parents more often than not have a negative view of the role of the Internet in learning, but young people almost always have a positive one. (via Clive Thompson)
