- 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)

Transit and Peering, Quick Web Interfaces, Open Source Licensing, and RC Roach
- 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.

Automating NES Games, Code Review Tool, SaaS KPIs, and No Free Lunch
- A General Technique for Automating NES Games — software that learns how to play NES games and plays them automatically, using an aesthetically pleasing technique. With video, research paper, and code.
- rietveld — open source tool like Mondrian, Google’s code review tool. Developed by Guido van Rossum, who developed Mondrian. Still being actively developed. (via Nelson Minar)
- KPI Dashboard for Early-Stage SaaS Startups — as Google Docs sheet. Nice.
- 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)
Street View Tiles Hacks, Policy Simulation, Map Tile Toolbox, and Connected Sensor Device HowTo
- HyperLapse — this won the Internet for April. Everyone else can go home. Check out this unbelievable video and source is available.
- 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)
HTML DRM, Visualizing Medical Sciences, Lifelong Learning, and Hardware Hackery
- 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.
- Visualizing the Topical Structure of the Medical Sciences: A Self-Organizing Map Approach (PLOSone) — a high-resolution visualization of the medical knowledge domain using the self-organizing map (SOM) method, based on a corpus of over two million publications.
- 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)

Google's Autonomous Cars, DIY BioPrinter, Forms Validation, and Machine Learning Workflow
- Google’s Driverless Car is Worth Trillions (Forbes) — Much of the reporting about Google’s driverless car has mistakenly focused on its science-fiction feel. […] In fact, the driverless car has broad implications for society, for the economy and for individual businesses. Just in the U.S., the car puts up for grab some $2 trillion a year in revenue and even more market cap. It creates business opportunities that dwarf Google’s current search-based business and unleashes existential challenges to market leaders across numerous industries, including car makers, auto insurers, energy companies and others that share in car-related revenue.
- DIY BioPrinter (Instructables) — Think of it as 3D printing, but with squishier ingredients! How to piggyback on inkjet printer technology to print with your own biomaterials. It’s an exciting time for biohackery: FOO Ewan Birney is kicking ass and taking names, he was just involved in a project storing and retrieving data from DNA.
- ADAMS — open sourced workflow tool for machine learning, from the excellent people at Waikato who brought you WEKA. ADAMS = Advanced Data mining And Machine learning System.
Turing Complete Users, Live Bootstrap Editor, Remix Exemptions, and Automatically Strengthening 3D Designs
- Turing Complete User — General Purpose Users can write an article in their e-mail client, layout their business card in Excel and shave in front of a web cam. They can also find a way to publish photos online without flickr, tweet without twitter, like without facebook, make a black frame around pictures without instagram, remove a black frame from an instagram picture and even wake up at 7:00 without a “wake up at 7:00” app. [… They are] users who have the ability to achieve their goals regardless of the primary purpose of an application or device. (via BoingBoing)
- Bootstrap Live Editor — a WYSIWYG HTML5 Editor built for Bootstrap. It offers a nice and elegant way to edit and beautify html content with Bootstrap-ready UI elements. I love how Bootstrap has become this framework for simpler website creation. I’m just disappointed they’re all startups chasing $ instead of being open source infrastructure.
- DCMA Exemption Recommended for Remix — recommended expanding the noncommercial remix exemption to cover both DVDs and online services. The reference to “motion pictures” covers “movies, television shows, commercials, news, DVD extras, etc.”
- New Tool Gives Structural Strength to 3-D Printed Works (Science Daily) — Findings were detailed in a paper presented during the SIGGRAPH 2012 conference in August. Former Purdue doctoral student Ondrej Stava created the software application, which automatically strengthens objects either by increasing the thickness of key structural elements or by adding struts. The tool also uses a third option, reducing the stress on structural elements by hollowing out overweight elements. (via BoingBoing)
Prank or mistake? A QR code on a TSA poster links to a non-TSA site.
Fred Trotter discovers that a QR code embedded in a TSA poster at the Orlando airport links to justinsomnia.org, which is about as far as you can get from a government website.
SQL Injection, Optical Stick, SQL for Crowdsourcing, and DIY Medical Records
- SQL Injection Pocket Reference (Google Docs) — just what it sounds like. (via ModSecurity SQL Injection Challenge: Lessons Learned)
- isostick: The Optical Drive in a Stick (KickStarter) — clever! A USB memory stick with drivers that emulate optical drives so you can boot off .iso files you’ve put on the memory stick. (via Extreme Tech)
- CrowdDB: Answering Queries with Crowdsourcing (Berkeley) — CrowdDB uses human input via crowdsourcing to process queries that neither database systems nor search engines can adequately answer. It uses SQL both as a language for posing complex queries and as a way to model data. (via Big Data)
- The DIY Electronic Medical Record (Bryce Roberts) — I had a record of my daily weight, my exercising (catalogued by type), my walking, my calories burned and now, with the addition of Zeo, my nightly sleep patterns. All of this data had been passively collected with little to no manual input required from me. Total investment in this personal sensor network was in the range of a couple hundred dollars. And, as I rummaged through my data it began to hit me that what I’ve really been doing is creating my own DIY Electronic Medical Record. The Quantified Self is about more than obsessively cataloguing your bowel movements in low-contrast infographics. I’m less enthused by the opportunities to publicly perform private data, a-la the wifi body scale, than I am by opportunities to gain personal insight.
