Google’s Borg, Georgia v. Malamud, SLAM-aware system, and SmartGPA

  1. Large-scale Cluster Management at Google with BorgGoogle’s Borg system is a cluster manager that runs hundreds of thousands of jobs, from many thousands of different applications, across a number of clusters, each with up to tens of thousands of machines. […] We present a summary of the Borg system architecture and features, important design decisions, a quantitative analysis of some of its policy decisions, and a qualitative examination of lessons learned from a decade of operational experience with it.
  2. Georgia Sues Carl Malamud (TechDirt) — for copyright infringement… for publishing an official annotated copy of the state's laws. […] the state points directly to the annotated version as the official laws of the state.
  3. Monocular SLAM Supported Object Recognition (PDF) — a monocular SLAM-aware object recognition system that is able to achieve considerably stronger recognition performance, as compared to classical object recognition systems that function on a frame-by-frame basis. (via Improving Object Recognition for Robots)
  4. SmartGPA: How Smartphones Can Assess and Predict Academic Performance of College Students (PDF) — We show that there are a number of important behavioral factors automatically inferred from smartphones that significantly correlate with term and cumulative GPA, including time series analysis of activity, conversational interaction, mobility, class attendance, studying, and partying.

4 ways the Raspberry Pi is being used in education

Get inspired to create, teach, and learn with the Raspberry Pi.

raspberries

The Raspberry Pi is a small computer that can be used for a variety of projects, and has been heralded as a great boon to education due to its flexibility and simplicity. While PcPro magazine noted in January of 2014 that Pi’s were “gathering dust” in classrooms, production has not ceased. The usage map is pretty impressive and the Raspberry Pi 2 was recently released.

In February of this year, the Raspberry Pi Foundation announced that they’re starting a mentoring program for people 16-21 years old. Here are four other ways that the Pi is being used in education and growing the tech community.

SCIP Berkeley Style, Regular Failures, Web Material Design, and Javascript Breakouts

  1. CS 61AS — Berkeley self-directed Structure and Interpretation of Computer Programs course.
  2. Harbingers of Failure (PDF) — We show that some customers, whom we call ‘Harbingers’ of failure, systematically purchase new products that flop. Their early adoption of a new product is a strong signal that a product will fail – the more they buy, the less likely the product will succeed. Firms can identify these customers either through past purchases of new products that failed, or through past purchases of existing products that few other customers purchase.
  3. Google Material Design LiteA library of Material Design components in CSS, JS, and HTML.
  4. Breakoutsvarious implementations of the classic game Breakout in numerous different [Javascript] engines.

DARPA Robotics Challenge, Math Instruction, Microservices Construction, and Crypto Hardware Sans Spooks

  1. Pocket Guide to DARPA Robotics Challenge Finals (Robohub) — The robots will start in a vehicle, drive to a simulated disaster building, and then they’ll have to open doors, walk on rubble, and use tools. Finally, they’ll have to climb a flight of stairs. The fastest team with the same amount of points for completing tasks will win. The main issues teams will face are communications with their robot and battery life: “Even the best batteries are still roughly 10 times less energy-dense than the kinds of fuels we all use to get around,” said Pratt.
  2. Dan Meyer’s Dissertation — Dan came up with a way to make math class social and the vocabulary sticky.
  3. Monolith First — echoes the idea that platforms should come from successful apps (the way AWS emerged from operating the Amazon store) rather than be designed before use.
  4. Building a More Assured Hardware Security Module (PDF) — proposal for An open source reference design for HSMs; Scalable, first cut in an FPGA and CPU, later allow higher speed options; Composable, e.g. “Give me a key store and signer suitable for DNSsec”; Reasonable assurance by being open, diverse design team, and an increasingly assured tool-chain. See cryptech.is for more info.

Army Cloud, Google Curriculum, Immutable Infrastructure, and Task Queues

  1. Army Cloud Computing Strategy (PDF) — aka: “what we hope to do without having done, to use what we’re doing to them.”
  2. Guide to Technical Development (Google) — This guide is a suggested path for university students to develop their technical skills academically and non-academically through self-paced, hands-on learning.
  3. Immutable Infrastructure is the Future (Michael DeHaan) — The future of configuration management systems is in deploying cloud infrastructure that will later run immutable systems via an API level.
  4. machineryan asynchronous task queue/job queue based on distributed message passing.

Edtech Advice, MEMS Sensors, Security in Go, and Building Teams

  1. Ed Tech Developer’s Guide (PDF) — U.S. government’s largely reasonable advice for educational technology startups. Nonetheless, take with a healthy dose of The Audrey Test.
  2. The Crazy-Tiny Next Generation of Computers — 1 cubic millimeter-sized sensors are coming. The only sound you might hear is a prolonged groan. That’s because these computers are just one cubic millimeter in size, and once they hit the floor, they’re gone. “We just lose them,” Dutta says. “It’s worse than jewelry.”
  3. Looking for Security Trouble Spots in Go — brief summary of the known security issues in and around Go code.
  4. The New Science of Building Great Teams (Sandy Pentland) — fascinating discussion of MIT’s Human Dynamics lab’s research into how great teams function. The data also reveal, at a higher level, that successful teams share several defining characteristics: 1. Everyone on the team talks and listens in roughly equal measure, keeping contributions short and sweet. 2. Members face one another, and their conversations and gestures are energetic. 3. Members connect directly with one another—not just with the team leader. 4. Members carry on back-channel or side conversations within the team. 5. Members periodically break, go exploring outside the team, and bring information back.

Onboarding UX, Productivity Vision, Bad ML, and Lifelong Learning

  1. User Onboarding Teardowns — the UX of new users. (via Andy Baio)
  2. Microsoft’s Productivity Vision — always-on thinged-up Internet everywhere, with predictions and magic by the dozen.
  3. Machine Learning Done WrongWhen dealing with small amounts of data, it’s reasonable to try as many algorithms as possible and to pick the best one since the cost of experimentation is low. But as we hit “big data,” it pays off to analyze the data upfront and then design the modeling pipeline (pre-processing, modeling, optimization algorithm, evaluation, productionization) accordingly.
  4. Ten Simple Rules for Lifelong Learning According to Richard Hamming (PLoScompBio) — Exponential growth of the amount of knowledge is a central feature of the modern era. As Hamming points out, since the time of Isaac Newton (1642/3-1726/7), the total amount of knowledge (including but not limited to technical fields) has doubled about every 17 years. At the same time, the half-life of technical knowledge has been estimated to be about 15 years. If the total amount of knowledge available today is x, then in 15 years the total amount of knowledge can be expected to be nearly 2x, while the amount of knowledge that has become obsolete will be about 0.5x. This means that the total amount of knowledge thought to be valid has increased from x to nearly 1.5x. Taken together, this means that if your daughter or son was born when you were 34 years old, the amount of knowledge she or he will be faced with on entering university at age 17 will be more than twice the amount you faced when you started college.

Matthew Effects, Office Dashboards, Below the API, and Robot Economies

  1. Matthew Effects in Reading (PDF) — Walberg, following Merton, has dubbed those educational sequences where early achievement spawns faster rates of subsequent achievement “Matthew effects,” after the Gospel according to Matthew: “For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath” (XXV:29) (via 2015 Troubling Trends and Possibilities in K-12)
  2. Real Time Dashboard for Office Plumbing (Flowing Data) — this is awesome.
  3. Working Below the API is a Dead End (Forbes) — Drivers are opting into a dichotomous workforce: the worker bees below the software layer have no opportunity for on-the-job training that advances their career, and compassionate social connections don’t pierce the software layer either. The skills they develop in driving are not an investment in their future. Once you introduce the software layer between ‘management’ (Uber’s full-time employees building the app and computer systems) and the human workers below the software layer (Uber’s drivers, Instacart’s delivery people), there’s no obvious path upwards. In fact, there’s a massive gap and no systems in place to bridge it. (via John Robb)
  4. The Real Robot Economy and the Bus Ticket Inspector (Guardian) — None of the cinematic worries about machines that take decisions about healthcare or military action are at play here. Hidden in these everyday, mundane interactions are different moral or ethical questions about the future of AI: if a job is affected but not taken over by a robot, how and when does the new system interact with a consumer? Is it ok to turn human social intelligence – managing a difficult customer – into a commodity? Is it ok that a decision lies with a handheld device, while the human is just a mouthpiece? Where “robots” is the usual shorthand for technology that replaces manual work. (via Dan Hill)

Mobile Supply Chain, Regulating the Interwebs, Meh MOOCs, and Security School

  1. The Home and the Mobile Supply Chain (Benedict Evans) — the small hardware start-up, and the cool new gizmos from drones to wearables, are possible because of the low price of components built at the scale required for Apple and other mobile device makers. (via Matt Webb)
  2. FCC Chairman Wheeler Proposes New Rules for Protecting the Open Internet (PDF) — America may yet have freedom. No blocking, no throttling, no paid prioritisation.
  3. The Future of College (Bill Gates) — The MOOC, by itself, doesn’t really change things, except for the very most motivated student. HALLELUJAH!
  4. Breaker 101 — 12-week online security course. $1,750 (cue eyes water). Putting the hacker back in hacker schools …

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.
