### Learning Poses, Kafkaesque Things, Hiring Research, and Robotic Movement

1. Apple Patent on Learning-based Estimation of Hand and Finger Pose — machine learning to identify gestures (hand poses) that works even when partially occluded. See writeup in Apple Insider.
2. The Internet of Kafkaesque Things (ACLU) — As computers are deployed in more regulatory roles, and therefore make more judgments about us, we may be afflicted with many more of the rigid, unjust rulings for which bureaucracies are so notorious.
3. Schmidt and Hunter (1998): Validity and Utility of Selection Methods in Personnel (PDF) — On the basis of meta-analytic findings, this article examines and summarizes what 85 years of research in personnel psychology has revealed about the validity of measures of 19 different selection methods that can be used in making decisions about hiring, training, and developmental assignments. (via Wired)
4. Complete Force Control in Constrained Under-actuated Mechanical Systems (Robohub) — Nori focuses on finding ways to advance the dynamic system of a robot – the forces that interact and make the system move. Key to developing dynamic movements in a robot is control, accompanied by the way the robot interacts with the environment. Nori talks us through the latest developments, designs, and formulas for floating-base/constrained mechanical systems, whole-body motion control of humanoid systems, whole-body dynamics computation on the iCub humanoid, and finishes with a video on recent implementations of whole-body motion control on the iCub. Video and download of presentation.

1. The Difference Between Direct Competition and DisruptionAs the ships grow, their engines have become vastly more efficient and sophisticated, the fuel mix has changed, and complex IT infrastructure has been put in place to coordinate the movement of the containers and ships. But fundamentally, the underlying cost structure of the business has not changed from 1950, when the first container ships carried a mere 500 to 800 containers across the world. (via Salim Virani)
2. The Impact of Copyright Policy Changes on Venture Capital Investment in Cloud Computing Companies (PDF) — Our findings suggest that decisions around the scope of copyrights can have significant impacts on investment and innovation. We find that VC investment in cloud computing firms increased significantly in the U.S. relative to the EU after the Cablevision decision. Our results suggest that the Cablevision decision led to additional incremental investment in U.S. cloud computing firms that ranged from $728 million to approximately$1.3 billion over the two-and-a-half years after the decision. When paired with the findings of the enhanced effects of VC investment relative to corporate investment, this may be the equivalent of $2 to$5 billion in traditional R&D investment.
3. Max Headroom Oral History“Anybody under the age of 25 just loved it. And anybody above that age was just completely confused.”
4. Auto Makers Say You Don’t Own Your Car (EFF) — Most of the automakers operating in the U.S. filed opposition comments through trade associations, along with a couple of other vehicle manufacturers. They warn that owners with the freedom to inspect and modify code will be capable of violating a wide range of laws and harming themselves and others. They say you shouldn’t be allowed to repair your own car because you might not do it right. They say you shouldn’t be allowed to modify the code in your car because you might defraud a used car purchaser by changing the mileage. They say no one should be allowed to even look at the code without the manufacturer’s permission because letting the public learn how cars work could help malicious hackers, “third-party software developers” (the horror!), and competitors.

### Moonshots, Decacorns, Leadership, and Deep Learning

1. How to Make Moonshots (Astro Teller) — Expecting a person to be a reliable backup for the [self-driving car] system was a fallacy. Once people trust the system, they trust it. Our success was itself a failure. We came quickly to the conclusion that we needed to make it clear to ourselves that the human was not a reliable backup — the car had to always be able to handle the situation. And the best way to make that clear was to design a car with no steering wheel — a car that could drive itself all of the time, from point A to point B, at the push of a button.
2. Billion-Dollar Math (Bloomberg) — There’s a new buzzword, “decacorn,” for those over $10 billion, which includes Airbnb, Dropbox, Pinterest, Snapchat, and Uber. It’s a made-up word based on a creature that doesn’t exist. “If you wake up in a room full of unicorns, you are dreaming,” Todd Dagres, a founding partner at Spark Capital, recently told Bloomberg News. Not just cute seeing our industry explained to the unwashed, but it’s the first time I’d seen decacorn. (The weather’s just dandy in my cave, thanks for asking). 3. What Impactful Engineering Leadership Looks Like — aside from the ugliness of “impactful,” notable for good advice. “When engineering management is done right, you’re focusing on three big things,” she says. “You’re directly supporting the people on your team; you’re managing execution and coordination across teams; and you’re stepping back to observe and evolve the broader organization and its processes as it grows.” 4. cxxnet“a fast, concise, distributed deep learning framework” that scales beyond a single GPU. ## Four short links: 12 February 2015 ### Finance Instrument, Retro Predictions, Trust Engineering, and Haptics 1. Update on indie.vcWe’ve worked with the team at Cooley to create an investment instrument that has elements of both debt and equity. Debt in that we will not be purchasing equity initially, but, unlike debt, there is no maturity date, no collateralization of assets and no recourse if it’s never paid back. The equity element will only become a factor if the participating company chooses to raise a round of financing or sell out to an acquiring company. We don’t have a clever acronym or name for this instrument yet, but I’m sure we’ll come up with something great. 2. How Nathan Barley Came True (Guardian) — if you haven’t already seen Nathan Barley, you should. It’s by the guy who did Black Mirror, and it’s both awful and authentic and predictive and retro and … painfully accurate about the horrors of our Internet/New Media industry. (via BoingBoing) 3. Trust Engineers (Radio Lab) — Facebook has a created a laboratory of human behavior the likes of which we’ve never seen. We peek into the work of Arturo Bejar and a team of researchers who are tweaking our online experience, bit by bit, to try to make the world a better place. Radio show of goodness. (via Flowing Data) 4. DARPA’S Haptix ProjectThe goal of the HAPTIX program is to provide amputees with prosthetic limb systems that feel and function like natural limbs, and to develop next-generation sensorimotor interfaces to drive and receive rich sensory content from these limbs. Today it’s prosthetic limbs for amputees, but within five years it’ll be augmented ad-driven realities for virtual currency ambient social recommendations. ## Four short links: 30 January 2015 ### FAA Rules, Sports UAVs, Woodcut Data, and Concurrent Programming 1. FAA to Regulate UAVs? (Forbes) — and the Executive Order will segment the privacy issues related to drones into two categories — public and private. For public drones (that is, drones purchased with federal dollars), the President’s order will establish a series of privacy and transparency guidelines. See also How ESPN is Shooting the X Games with Drones (Popular Mechanics)—it’s all fun and games until someone puts out their eye with a quadrocopter. The tough part will be keeping within the tight restrictions the FAA gave them. Because drones can’t be flown above a crowd, Calcinari says, “We basically had to build a 500-foot radius around them, where the public can’t go.” The drones will fly over sections of the course that are away from the crowds, where only ESPN production employees will be. That rule is part of why we haven’t seen drones at college football games. 2. Milestones for SaaS Companies“Getting from$0-1m is impossible. Getting from $1-10m is unlikely. And getting from$10-100m is inevitable.” —Jason Lemkin, ex-CEO of Echosign. The article proposes some significant milestones, and they ring true. Making money is generally hard. The nature of the hard changes with the amount of money you have and the amount you’re trying to make, but if it were easy, then we’d structure our society on something else.
3. Woodcut Data VisualisationRecently, I learned how to operate a laser cutter. It’s been a whole lot of fun, and I wanted to share my experiences creating woodcut data visualizations using just D3. I love it when data visualisations break out of the glass rectangle.
4. Why is Concurrent Programming Hard?on the one hand there is not a single concurrency abstraction that fits all problems, and on the other hand the various different abstractions are rarely designed to be used in combination with each other. We are due for a revolution in programming, something to help us make sense of the modern systems made of more moving parts than our feeble grey matter can model and intuit about.

### Security Videos, Network Simulation, UX Book, and Profit in Perspective

1. ShmooCon 2015 Videos — videos to security talks from ShmooCon 2015.
2. Comcast (Github) — Comcast is a tool designed to simulate common network problems like latency, bandwidth restrictions, and dropped/reordered/corrupted packets. On BSD-derived systems such as OSX, we use tools like ipfw and pfctl to inject failure. On Linux, we use iptables and tc. Comcast is merely a thin wrapper around these controls.
3. The UX ReaderThis ebook is a collection of the most popular articles from our [MailChimp] UX Newsletter, along with some exclusive content.
4. Bad AssumptionsApple lost more money to currency fluctuations than Google makes in a quarter.

### Autonomous Corporations, Abstract Thought, Down Rounds, and Distributed Messaging

1. Decentralised Autonomous Corporations — Charlie Stross’s near-future fiction of Accelerando comes closer to reality: Malice – revenge for waking him up – sharpens Manfred’s voice. “The president of agalmic.holdings.root.184.97.AB5 is agalmic.holdings.root.184.97.201. The secretary is agalmic.holdings.root.184.D5, and the chair is agalmic.holdings.root.184.E8.FF. All the shares are owned by those companies in equal measure, and I can tell you that their regulations are written in Python. Have a nice day, now!” He thumps the bedside phone control and sits up, yawning, then pushes the do-not-disturb button before it can interrupt again. After a moment he stands up and stretches, then heads to the bathroom to brush his teeth, comb his hair, and figure out where the lawsuit originated and how a human being managed to get far enough through his web of robot companies to bug him.
2. Coding is Not the New Literacy (Chris Grainger) — We build mental models of everything – from how to tie our shoes to the way macro-economic systems work. With these, we make decisions, predictions, and understand our experiences. If we want computers to be able to compute for us, then we have to accurately extract these models from our heads and record them. Writing Python isn’t the fundamental skill we need to teach people. Modeling systems is. Amen!
3. Let’s Stop Laughing at Groupon (Fortune) — it is much easier to survive a valuation decline as a public company than as a private one.
4. nsq — Bitly’s open sourced realtime distributed messaging platform.

### Feudal Employment, Untrusted Computing, Nerd Entitlement, and Paxos Explained

1. Governance for the New Class of Worker (Matt Webb) — there is a new class of worker. They’re not inside the company – not benefiting from job security or healthcare – but their livelihoods in large part dependent on it, the transaction cost of moving to a competitor deliberately kept high. Or the worker is, without seeing any of the upside of success, taking on the risk or bearing the cost of the company’s expansion and operation.
2. Hidden Code in Your Chipset (Slideshare) — there’s a processor that supervises your processor, and it’s astonishingly fully-featured (to the point of having privileged access to the network and being able to run Java code).
3. On Nerd EntitlementPrivilege doesn’t mean you don’t suffer. The best part of 2014 was the tech/net feminist consciousness-raising/uprising. That’s probably the wrong label for it, but bullshit is being called that was ignored years ago. I think we’ve collectively found the next thing we fix that future generations will look back on us and wonder why it went unremarked-upon for so long.
4. Understanding Paxos — a simple introduction, with animations, to one of the key algorithms in distributed systems.

### Open Source Submersible, Web Language, Cheap Robot Arm, and Visualisation Trends

1. OpenROV — open source submersible, funded in 1 day on Kickstarter, now available for purchase.
2. Ur/Web — web application language that’s functional, pure, statically typed, and strict. (via IT World)
3. MeArm (Thingiverse) — a low cost robot arm. The meArm is designed to be light weight and inexpensive – to be the perfect introduction to robotics. Design on Thingiverse, kickstarting the controller.
4. Eric Rodenbeck on Running a Studio (Flowing Data) — Stamen’s founder on the challenges of staying current. I hadn’t realised quite how quickly the visualisation field is changing.
