### The Contract, Fixing Signin, Pi Gaming, and Glitchy Marketing Constructs

1. The Unengageables (Dan Meyer) — They signed their “didactic contract” years and years ago. They signed it. Their math teachers signed it. The agreement says that the teacher comes into class, tells them what they’re going to learn, and shows them three examples of it. In return, the students take what their teacher showed them and reproduce it twenty times before leaving class. Then they go home with an assignment to reproduce it twenty more times. Then here you come, Ms. I-Just-Got-Back-From-A-Workshop, and you want to change the agreement? Yeah, you’ll hear from their attorney. Applies to management as much as to teaching.
2. Fixing SigninThe general principle can be stated simply, in two parts: first, give users a trust-worthy way to identify themselves. Second, do so with as little information as possible, because users don’t want to (and simply can’t) remember things like passwords in a secure way. (via Tim Bray)
3. Retro Gaming with Raspberry Pi (Adafruit) — finally, a clear incentive for kids to work through the frustration of setting up their own Linux box.
4. Mieko Haire — Apple’s fictious demo lady. Or is she fictitious? This is a new aesthetic-esque glitch, but while most glitches are glitches because you see something that doesn’t exist, this is glitchy because the fictions are actual people. Ok, maybe I need to lay off the peyote.

### Geodata DVCS, Monitoring Stack, Robotic Roaches, and Audio Destress

1. geogit — opengeo project exploring the use of distributed management of spatial data. [...] adapts [git's] core concepts to handle versioning of geospatial data. Shapefiles, PostGIS or SpatiaLite data stored in a change-tracking repository, with all the fun gut features for branching history, merging, remote/local repos, etc. BSD-licensed. First sound attempt at open source data management.
2. Introducing Loupe — Etsy’s monitoring stack. It consists of two parts: Skyline and Oculus. We first use Skyline to detect anomalous metrics. Then, we search for that metric in Oculus, to see if any other metrics look similar. At that point, we can make an informed diagnosis and hopefully fix the problem.
3. Bluetooth-Controlled Robotic Cockroach (Kickstarter) — ’nuff said. (via BoingBoing)
4. Nature Sounds of New Zealand — if all the surveillance roboroach anomaly detection drone printing stories get to you, put this on headphones and recharge. (caution: contains nature)

### 3D Visualization, Printing On Any Surface, Rebuilding Reality, and Emotions as Data

1. For Example — amazing discussion of 3D visualization techniques, full of examples using the D3.js library and bl.ocks.org example gist system. Gorgeous and informative.
2. Anti-Gravity 3D Printer — uses strands to sculpt on any surface. (via Slashdot)
3. How 3D Printing Will Rebuild Reality (BoingBoing) — But even though home 3D-printing has received substantial publicity of late, it is in the industrial sector where the technology will probably make its most significant near-term impact on the world both by manufacturing improved commercial products and by stimulating industry to develop next-generation fab methods and machines that could one day truly bring 3D-printing home to users in a real way.
4. The Emotional Side of Big Data — Personal Democracy Forum 2013 talk by Sara Critchfield, on reframing emotion as data for decision-making. (via Quartz)

### Pseudo Memetics, Top Pinch or Bottom Pinch, Innovation Cartography, and Awesome Compilation Hackery

1. Anatomy of Two Memes — comparing the spread of Gangnam Style to Harlem Shake. Memes are like currencies: you need to balance accessibility (or ‘money supply’) and inflation. Gangnam Style became globally accessible through top-down mainstream sources (High Popularity), but this gave it high social inflation so it wasn’t valuable to share (Low Shareability). However, scale sustained its long term growth. Harlem Shake was not as easily accessible because it was driven more by small communities (Low Popularity), but for the same reason, being less easily accessible, it remained highly valuable (High Shareability). Lack of scale was what made Harlem Shake growth short-term and eventually killed it prematurely. Caution: contains fauxconomics.
2. Handedness (Github) — determine left or right handedness from pinch gesture.
3. Innovation Cartography — video of a talk by Richard Jefferson of Cambia’s lens, on the imperative to innovate held at the Skoll World Forum on Social Enterprise. His story of maritime cartography (starts around 5m50s) is awesome.
4. Statically Recompiling NES Games into Native Executables with LLVM and Go — or “crack for Nat” as I like to translate that title.

### Open Source BigTable, Robots Lost, Changing the World, Secrecy Binge

1. Accumulo — NSA’s BigTable implementation, released as an Apache project.
2. How the Robots Lost (Business Week) — the decline of high-frequency trading profits (basically, markets worked and imbalances in speed and knowledge have been corrected). Notable for the regulators getting access to the technology that the traders had: Last fall the SEC said it would pay Tradeworx, a high-frequency trading firm, $2.5 million to use its data collection system as the basic platform for a new surveillance operation. Code-named Midas (Market Information Data Analytics System), it scours the market for data from all 13 public exchanges. Midas went live in February. The SEC can now detect anomalous situations in the market, such as a trader spamming an exchange with thousands of fake orders, before they show up on blogs like Nanex and ZeroHedge. If Midas sees something odd, Berman’s team can look at trading data on a deeper level, millisecond by millisecond. 3. PRISM: Surprised? (Danny O’Brien) — I really don’t agree with the people who think “We don’t have the collective will”, as though there’s some magical way things got done in the past when everyone was in accord and surprised all the time. It’s always hard work to change the world. Endless, dull hard work. Ten years later, when you’ve freed the slaves or beat the Nazis everyone is like “WHY CAN’T IT BE AS EASY TO CHANGE THIS AS THAT WAS, BACK IN THE GOOD OLD DAYS. I GUESS WE’RE ALL JUST SHEEPLE THESE DAYS.” 4. What We Don’t Know About Spying on Citizens is Scarier Than What We Do Know (Bruce Schneier) — The U.S. government is on a secrecy binge. It overclassifies more information than ever. And we learn, again and again, that our government regularly classifies things not because they need to be secret, but because their release would be embarrassing. Open source BigTable implementation: free. Data gathering operation around it:$20M/year. Irony in having the extent of authoritarian Big Brother government secrecy questioned just as a whistleblower’s military trial is held “off the record”: priceless.

### In-Browser p2p, Thinking About The Future, Disruptive Tech, and Crowdsourcing Transcription

1. ShareFest — peer-to-peer file sharing in the browser. Source on GitHub. (via Andy Baio)
2. Media for Thinking the Unthinkable (Bret Victor) — “Right now, today, we can’t see the thing, at all, that’s going to be the most important 100 years from now.” We cannot see the thing. At all. But whatever that thing is — people will have to think it. And we can, right now, today, prepare powerful ways of thinking for these people. We can build the tools that make it possible to think that thing. (via Matt Jones)
3. McKinsey Report on Disruptive Technologies (McKinsey) — the list: Mobile Internet; Automation of knowledge work; Internet of Things; Cloud technology; Advanced Robotics; Autonomous and near-autonomous vehicles; Next-generation genomics; Energy storage; 3D Printing; Advanced Materials; Advanced Oil and Gas exploration and recovery; Renewable energy.
4. The Only Public Transcript of the Bradley Manning Trial Will be Produced on a Crowd-Funded Typewriter[t]he fact that a volunteer stenographer is providing the only comprehensive source of information about such a monumental event is pretty absurd.
