Google MillWheel, 20yo Bug, Fast Real-Time Visualizations, and Google's Speed King

  1. MillWheel: Fault-Tolerant Stream Processing at Internet Scale — Google Research paper on the tech underlying the new cloud DataFlow tool. Watch the video. Yow.
  2. The Integer Overflow Bug That Went to Mars — long-standing (20 year old!) bug in a compression library prompts a wave of new releases. No word yet on whether NASA will upgrade the rover to avoid being pwned by Martian script kiddies. (update: I fell for a self-promoter. The Martians will need to find another attack vector. Huzzah!)
  3. epoch (github) — Fastly-produced open source general purpose real-time charting library for building beautiful, smooth, and high performance visualizations.
  4. Achieving Rapid Response Times in Large Online Services (YouTube) — Jeff Dean‘s keynote at Velocity. He wrote … a lot of things for this. And now he’s into deep learning ….

IoT Future, Latency Numbers, Mobile Performance, and Minimum Viable Bureaucracy

  1. Charlie Stross on 2034every object in the real world is going to be providing a constant stream of metadata about its environment — and I mean every object. The frameworks used for channeling this firehose of environment data are going to be insecure and ramshackle, with foundations built on decades-old design errors. (via BoingBoing)
  2. Latency Numbers Every Programmer Should Know — awesome animation so you can see how important “constants” which drive design decisions have changed over time.
  3. Extreme Web Performance for Mobile Devices (Slideshare) — notes from Maximiliano Firtman’s Velocity tutorial.
  4. Minimum Viable Bureaucracy (Laura Thomson) — notes from her Velocity talk. A portion of engineer’s time must be spent on what engineer thinks is important. It may be 100%. It may be 60%, 40%, 20%. But it should never be zero.

Mobile Hacks, Advertising Returns, Solid Writeup, and Predicted Future

  1. Researchers Find and Decode the Spy Tools Governments Use to Hijack Phones (Wired) — I’m fascinated to learn there’s an Italian company making (and selling) the mobile phone rootkits that governments use.
  2. On the Near Impossibility of Measuring the Returns on Advertising (PDF) — Statistical evidence from the randomized trials is very weak because the individual-level sales are incredibly volatile relative to the per capita cost of a campaign—a “small” impact on a noisy dependent variable can generate positive returns. (via Slate)
  3. Reflections on Solid Conference — recap of the conference, great for those of us who couldn’t make it. “Software is eating the world…. Hardware gives it teeth.” – Renee DiResta
  4. Cybernation: The Silent Conquest (1962)[When] computers acquire the necessary capabilities…speeded-up data processing and interpretation will be necessary if professional services are to be rendered with any adequacy. Once the computers are in operation, the need for additional professional people may be only moderate [...] There will be a small, almost separate, society of people in rapport with the advanced computers. These cyberneticians will have established a relationship with their machines that cannot be shared with the average man any more than the average man today can understand the problems of molecular biology, nuclear physics, or neuropsychiatry. Indeed, many scholars will not have the capacity to share their knowledge or feeling about this new man-machine relationship. Those with the talent for the work probably will have to develop it from childhood and will be trained as intensively as the classical ballerina. (via Simon Wardley)

Failure of Imagination, Meat Failure Mode, Grand Challenges, and Data Programming

  1. Maximum Happy Imagination (Matt Jones) — questioning the true vision of Marc Andreessen’s recent Twitter discourse on the great future that awaits us. His analogies run out in the 20th century when it comes to the political, social and economic implications of his maximum happy imagination.
  2. The MirrortocracyIt’s astonishing how many of the people conducting interviews and passing judgement on the careers of candidates have had no training at all on how to do it well. Aside from their own interviews, they may not have ever seen one. I’m all for learning on your own but at least when you write a program wrong it breaks. Without a natural feedback loop, interviewing mostly runs on myth and survivor bias.
  3. Longitude Prize — six prize areas, Grand Challenge style, in clean flight, antibiotic resistance, dementia, food, water, and overcoming paralysis. Mysteriously none for library system that avoids DLL hell.
  4. The Re-Emergence of DatalogMichael Fogus overviews Datalog and provides examples of how it is implemented and used in Datomic, Cascalog, and the Bacwn Clojure library. See also notes from the talk.

Blockchain Intro, Machine Collaboration, Safety Systems Thinking, and Where Keystrokes Go To Die

  1. Minimum Viable Block ChainWhat follows is an attempt to explain, from the ground up, why the particular pieces (digital signatures, proof-of-work, transaction blocks) are needed, and how they all come together to form the “minimum viable block chain” with all of its remarkable properties.
  2. Common Ground and Coordination in Joint Activity (PDF) — research paper on the components and requirements and failure modes of collaboration, with an eye to how machine actors can participate as collaborators. (via John Allspaw)
  3. Engineering a Safer World (Nancy Leveson) — Systems thinking applied to safety. Free download of the MIT Press ebook. (via John Allspaw)
  4. Scott Hanselman’s TipsKeep your emails to 3-4 sentences, Hanselman says. Anything longer should be on a blog or wiki or on your product’s documentation, FAQ or knowledge base. “Anywhere in the world except email because email is where you keystrokes go to die,” he says.

Available Data, Goal Setting, Real Tech, and Gamification Numbers

  1. Dynamo and BigTable — good preso overview of two approaches to solving availability and consistency in the event of server failure or network partition.
  2. Goals Gone Wild (PDF) — In this article, we argue that the beneficial effects of goal setting have been overstated and that systematic harm caused by goal setting has been largely ignored. We identify specific side effects associated with goal setting, including a narrow focus that neglects non-goal areas, a rise in unethical behavior, distorted risk preferences, corrosion of organizational culture, and reduced intrinsic motivation.
  3. Tech Isn’t All Brogrammers (Alexis Madrigal) — a reminder that there are real scientists and engineers in Silicon Valley working on problems considerably harder than selling ads and delivering pet food to one another. (via Brian Behlendorf)
  4. Numbers from 90+ Gamification Case Studies — cherry-picked anecdata for your business cases.

Interactive Narrative, Robot Economies, 8-Bit Philosophy, and Citizens and Sensors

  1. odyssey.js — storytelling tool to assemble interactive stories from narrative, pictures, maps.
  2. Our Work Here is Done: Visions of a Robot Economy (NESTA) — free downloadable ebook containing pieces from a variety of authors covering economics, engineering, history, philosophy and innovation studies. (via Robot Economics)
  3. 8-Bit Philosophy — learn philosophy with an 8-bit aesthetic. (via EdSurge)
  4. Sensors and Citizens: Finding Balance in the New Urban Reality (Frog Design) — as the sensor systems themselves become capable of autonomous data collection and information creation, we will begin to encounter closed-loop spatial sensing networks capable not only of taking instructions, but also of taking action. When that happens, nearly every industry and government imaginable—and your daily life—will be deeply affected. This is exciting, scary, and inevitable.

Browser Crypto, Real Time Consistency, Exploring CS, and CS as Social Movement

  1. Javascript Cryptography Considered Harmful — tl;dr: “don’t”. If you don’t trust the network to deliver a password, or, worse, don’t trust the server not to keep user secrets, you can’t trust them to deliver security code. The same attacker who was sniffing passwords or reading diaries before you introduce crypto is simply hijacking crypto code after you do.
  2. Eventual Consistency in Real Time Apps — answering How do you ensure that your local model is in sync with what’s stored on the backend?
  3. Exploring CSBoth courses are designed to teach the fundamental concepts and big ideas of computing along with coding, and to inspire kids about computer science’s creative potential to transform society.
  4. Why Computer Literacy Is Key To Winning the 21st Century (Mother Jones) — [teaching CS to] middle and high schoolers at the UCLA Community School, an experimental new public K-12 school. “I saw this as a new frontier in the social-justice fight,” she says. “I tell my students, ‘I don’t necessarily want to teach you how to get rich. I want to teach you to be a good citizen.’”

Decentralised Consensus, Disruption Critiqued, Digital Reputation, and Stuff That Matters

  1. Erisa platform which allows developers and users to deploy consensus driven applications which rely on decentralized architecture and a consensus driven blockchain database backend. Open source (modified MIT).
  2. The Disruption Machine (New Yorker) — long detailed critique of the “disruption” hypothesis of Clayton Christensen, particularly questioning the case studies cited in The Innovator’s Dilemma.
  3. Web Reputation Systems and the Real World (Randy Farmer) — Don’t cross the streams. Good digital reputations should always be context-limited: the nature of the inputs should constrain the use of the reputation scores that are output.
  4. Bill and Melinda Gates Commencement Speech (Quartz) — excellent urging to work on stuff that matters. The pessimists are wrong in my view, but they’re not crazy. If innovation is purely market- driven and we don’t focus it on the big inequities, then we could have amazing advances and inventions that leave the world even more divided.

Decision Trees, Decision Modifications, Mobile Patents, Web Client

  1. Quick DT — open source (Java) decision tree learner.
  2. Revealing Hidden Changes to Supreme Court OpinionsWHEREAS, It is now well-documented that the Supreme Court of the United States makes changes to its opinions after the opinion is published; and WHEREAS, Only “Four legal publishers are granted access to “change pages” that show all revisions. Those documents are not made public, and the court refused to provide copies to The New York Times”; and WHEREAS, git makes it easy to identify when changes have been made; RESOLVED, I shall apply a cron job to at least identify when the actual PDF has changed so everyone can see which documents have changed.
  3. Microsoft’s “Killer” Android Patents Revealed (Ars Technica) — Chinese Government required them disclosed as part of MSFT-Nokia merger. The patent lists are strategically significant, because Microsoft has managed to build a huge patent-licensing business by taxing Android phones without revealing what kind of legal leverage they really have over those phones.
  4. HTTPiea command line HTTP client, a user-friendly HTTP client.
