Data Science, Temporal Graph, Biomedical Superstars, and VR Primer

  1. 50 Years of Data Science (PDF) — Because all of science itself will soon become data that can be mined, the imminent revolution in Data Science is not about mere “scaling up,” but instead the emergence of scientific studies of data analysis science-wide.
  2. badwolfa temporal graph store from Google.
  3. Why Biomedical Superstars are Signing on with Google (Nature) — “To go all the way from foundational first principles to execution of vision was the initial draw, and that’s what has continued to keep me here.” Research to retail, at Google scale.
  4. VR Basics — intro to terminology and hardware in the next gen of hardware, in case you’re late to the goldrush^w exciting field.

A developer’s introduction to 3D animation and Blender

An overview of the 3D animation process using Blender.


Creating 3D animations is like writing software. Both processes require
knowing certain industry terms. Some animation terms are:

  • Modeling
  • Texturing
  • Rigging
  • Setting up the scene with cameras, lights, and other effects
  • Animating
  • Rendering

Let’s define each of these, and then we’ll dig into some code with Blender’s API.

Modeling is the process of creating 3D models. One way is to represent the 3D model as points in 3D space. Each point, or vertex, has 3 coordinates: an X, an Y, and a Z coordinate, to define its location in 3D space. A pair of vertices can be connected by an edge, and edges bound polygons called faces. These faces define the surface of the model. Modeling is all about creating these sets of vertices, edges, and faces.


To create a model, we usually start with a primitive shape (like a sphere or a cube) and reshape it into what we’d like. Individual vertices, edges, and faces can be repositioned. New vertices, edges, and faces can be added to the basic model through simple operations. Two common ones are extrusion and subdivision.

USA Hire, AR Game, CS Cheatsheet, and 3D Printing Cured Resin

  1. David Recordon Joins US GovtThis afternoon, President Barack Obama will announce a newly created position for David Recordon, who has worked as one of Facebook’s engineering directors since 2009. Recordon will join the White House as the director of information technology. Obama building an A team from Foo Campers.
  2. MagicLeap/Weta Workshop FPS in AR (YouTube) — fun!
  3. Theoretical Computer Science Cheat Sheet (PDF) — how to appear smart.
  4. Carbon3DTraditional 3D printing requires a number of mechanical steps, repeated over and over again in a layer-by-layer approach. CLIP is a chemical process that carefully balances light and oxygen to eliminate the mechanical steps and the layers. It works by projecting light through an oxygen-permeable window into a reservoir of UV curable resin. The build platform lifts continuously as the object is grown.

3D Shares, Autonomous Golf Carts, Competitive Solar, and Interesting Data Problems

  1. Cooper-Hewitt Shows How to Share 3D Scan Data Right (Makezine) — important as we move to a web of physical models, maps, and designs.
  2. Singapore Tests Autonomous Golfcarts (Robohub) — a reminder that the future may not necessarily look like someone used the clone tool to paint Silicon Valley over the world.
  3. Solar Hits Parity in 10 States, 47 by 2016 (Bloomberg) — The reason solar-power generation will increasingly dominate: it’s a technology, not a fuel. As such, efficiency increases and prices fall as time goes on. The price of Earth’s limited fossil fuels tends to go the other direction.
  4. Facebook’s Top Open Data Problems (Facebook Research) — even if you’re not interested in Facebook’s Very First World Problems, this is full of factoids like Facebook’s social graph store TAO, for example, provides access to tens of petabytes of data, but answers most queries by checking a single page in a single machine.

Feedback Surprises, Ownership Changes, Teaching Lessons, and 3D Retail

  1. How Community Feedback Shapes Behaviour (PDF) — Not only do authors of negatively-evaluated content contribute more, but also their future posts are of lower quality, and are perceived by the community as such. Moreover, these authors are more likely to subsequently evaluate their fellow users negatively, percolating these effects through the community. In contrast, positive feedback does not carry similar effects, and neither encourages rewarded authors to write more, nor improves the quality of their posts. Interestingly, the authors that receive no feedback are most likely to leave a community. Furthermore, a structural analysis of the voter network reveals that evaluations polarize the community the most when positive and negative votes are equally split.
  2. When Everything Works Like Your Cell Phone (The Atlantic) — our relationship to ownership is about to undergo a wild transformation.
  3. Teaching Me Softly — article of anecdotes drawing parallels between case studies in machine learning and things we know about human learning.
  4. SuperAwesome Me (3D Print) — Walmart to install 3d scanning booths and 3d printers so you can put your own head on a Hasbro action figure. Hasbro have the religion: they also paired with Shapeways for superfanart.com. (via John Battelle)

Reverse Engineering, Incident Response, 3D Museum, and Social Prediction

  1. Reverse Engineering for Beginners (GitHub) — from assembly language through stack overflows, dongles, and more.
  2. Incident Response at Heroku — the difference between good and bad shops is that good shops have a routine for exceptions.
  3. 3D Petrie MuseumThe Petrie Museum of Egyptian Archaeology has one of the largest ancient Egyptian and Sudanese collections in the world and they’ve put 3D models of their goods online. Not (yet) available for download, only viewing which seem a bug.
  4. Sandy Pentland on Wearables (The Verge) — Pentland was also Nathan Eagle’s graduate advisor, and behind the Reality Mining work at MIT. Check out his sociometer: One study revealed that the sociometer helps discern when someone is bluffing at poker roughly 70 percent of the time; another found that a wearer can determine who will win a negotiation within the first five minutes with 87 percent accuracy; yet another concluded that one can accurately predict the success of a speed date before the participants do.

Chicago Code, 3D Smithsonian Data, AI Controlling Everything, and Game TCP

  1. The Virtuous Pipeline of Code (Public Resource) — Chicago partnering with Public Resource to open its legal codes for good. “This is great! What can we do to help?” Bravo Chicago, and everyone else—take note!
  2. Smithsonian’s 3D Data — models of 21 objects, from a gunboat to the Wright Brothers’ plane, to a wooly mammoth skeleton, to Lincoln’s life masks. I wasn’t able to find a rights statement on the site which explicitly governed the 3D models. (via Smithsonian Magazine)
  3. Anki’s Robot Cars (Xconomy) — The common characteristics of these future products, in Sofman’s mind: “Relatively simple and elegant hardware; incredibly complicated software; and Web and wireless connectivity to be able to continually expand the experience over time.” (via Slashdot)
  4. An Empirical Evaluation of TCP Performance in Online GamesWe show that because TCP was originally designed for unidirectional and network-limited bulk data transfers, it cannot adapt well to MMORPG traffic. In particular, the window-based congestion control and the fast retransmit algorithm for loss recovery are ineffective. Furthermore, TCP is overkill, as not every game packet needs to be transmitted in a reliably and orderly manner. We also show that the degraded network performance did impact users’ willingness to continue a game.
