I Heart Logs, CS50 Eating The World, Meeting Transcripts, Binary Analysis

  1. I Heart Logs — I linked to Jay Kreps’s awesome blog post twice, and now he’s expanded it into a slim O’Reilly volume which I shall press into the hands of every engineer I meet. Have you heard the Good News?
  2. CS50 Record Numbers — nearly 12% of Harvard now takes Intro to CS. (via Greg Linden)
  3. SayIt — open source from MySociety, a whole new way to organise, publish,
    and share your transcripts
    . They really want to make a better experience for sharing and organising transcripts of meetings.
  4. BAP — Binary Analysis Platform from CMU. Translates binary into assembly and then into an intermediate language which explicitly represents the side effects of assembly instructions, such as flag computations.

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)

Visual Python, Scraping and Screenshotting, Un-free Speech, IP Law Textbook

  1. PlotDeviceA Python-based graphics language for designers, developers, and tinkerers. More in the easy-to-get-started + visual realm, like Processing. (via Andy Baio)
  2. Scumblr and Sketchy Search — Netflix open sourcing some scraping, screenshot, and workflow tools their security team uses to monitor discussion of themselves.
  3. Should Twitter, Facebook and Google Executives be the Arbiters of What We See and Read? (Glenn Greenwald) — In the digital age, we are nearing the point where an idea banished by Twitter, Facebook and Google all but vanishes from public discourse entirely, and that is only going to become more true as those companies grow even further. Whatever else is true, the implications of having those companies make lists of permitted and prohibited ideas are far more significant than when ordinary private companies do the same thing.
  4. Intellectual Property: Law and the Information Society; Cases and Materials (PDF) — James Boyle and Jennifer Jenkins’ open law textbook on IP (which even explores the question of whether that’s a valid and meaningful term). (via James Boyle)

Open Data Glue, Smithsonian Crowdsourcing, MIT Family Creativity, and Hardware Owie

  1. Datan open source project that provides a streaming interface between every file format and data storage backend. See the Wired piece on it.
  2. Smithsonian Crowdsourcing Transcription (Smithsonian) — 49 volunteers transcribed 200 pages of correspondence between the Monuments Men in a week. Soon it’ll be mathematics test questions: “if 49 people transcribe 200 pages in 7 days, how many weeks will it take …”
  3. MIT Guide to Family CompSci SessionsThis guide is for educators, community center staff, and volunteers interested in engaging their young people and their families to become designers and inventors in their community.
  4. What to Do When You Screw up 2,000 Orders (SparkFun) — even hardware companies need to do retrospectives.

Adjustable Ethics, Face Projection, Mod Minecraft, and Robot Grasp

  1. Robot Cars with Adjustable Ethics Settings (Wired) — no user-servicable virtues inside. In an important sense, any injury that results from our ethics setting may be premeditated if it’s foreseen.
  2. Face-Tracking with Projection Mapping: Weird (BoingBoing) — amazing video of real-time face mapping combined with projection mapping. It is, as promised, weird.
  3. LearnToModteaches you how to code by teaching you how to mod Minecraft. It gives you two different ways to code: with blocks or with Javascript. Preorder for Oct 2014 promised release. (via Wired)
  4. Grasping with Robots: Which Object is in Reach? (Robohub) — This post is part of our ongoing efforts to make the latest papers in robotics accessible to a general audience.a new approach to build a comprehensive representation of the capabilities of a robot related to reaching and grasping. Very short, very readable, as promised.

Data Storytelling Tools, Massive Dataset Mining, Failed Crowdsourcing, and IoT Networking

  1. MisoDataset, a JavaScript client-side data management and transformation library, Storyboard, a state and flow-control management library & d3.chart, a framework for creating reusable charts with d3.js. Open source designed to expedite the creation of high-quality interactive storytelling and data visualisation content.
  2. Mining of Massive Datasets (PDF) — book by Stanford profs, focuses on data mining of very large amounts of data, that is, data so large it does not fit in main memory. Because of the emphasis on size, many of our examples are about the Web or data derived from the Web. Further, the book takes an algorithmic point of view: data mining is about applying algorithms to data, rather than using data to “train” a machine-learning engine of some sort.
  3. Lessons from Iceland’s Failed Crowdsourced Constitution (Slate) — Though the crowdsourcing moment could have led to a virtuous deliberative feedback loop between the crowd and the Constitutional Council, the latter did not seem to have the time, tools, or training necessary to process carefully the crowd’s input, explain its use of it, let alone return consistent feedback on it to the public.
  4. Thread a ZigBee Killer?Thread is Nest’s home automation networking stack, which can use the same hardware components as ZigBee, but which is not compatible, also not open source. The Novell NetWare of Things. Nick Hunn makes argument that Google (via Nest) are taking aim at ZigBee: it’s Google and Nest saying “ZigBee doesn’t work”.

Design Reviews, Gaudy Palette, Web Components, and Creative Coding

  1. Questions to Ask when Reviewing a Design (GDS) — GDS made stickers, but I might just put this in poster form on the wall. They missed, “can you make it pop?” though.
  2. Saturated — wonderfully unsubdued web palette for prototyping. Nobody will ask “can you make it pop?” with this colour scheme.
  3. Component Kitchen — and customelements are both catalogues of web components.
  4. Summer Immersive 2014 (GitHub) — curriculum and materials for a ten week program devoted to learning the art of creative coding. (via Shawn Allen)

Software Ethics, Learning Challenges, Workplace Harassment, and Logging for Postmortems

  1. Misjudgements Will Drive Social Trials Underground (Nature) — 34 ethicists write to explain why they see Facebook’s mood-influence trials as not an egregious breach of either ethics or law. Notable: No one knows whether exposure to a stream of baby announcements, job promotions and humble brags makes Facebook’s one billion users sadder or happier. The exposure is a social experiment in which users become guinea pigs, but the effects will not be known unless they are studied.[…] But the extreme response to this study, some of which seems to have been made without full understanding of what it entailed or what legal and ethical standards require, could result in such research being done in secret or not at all. Compare wisdom of the ethicists to wisdom of the crowd. (via Kate Crawford)
  2. Problem-Free Activity in the Mathematics Classroom (PDF) — interesting not just for the bland crap work we make kids do, but for the summary of five types of need that stimulate learning: for certainty (“which of the two is right?”), for causality (“did X cause Y?”, “what will happen next?”), for computation (“how much will it cost?”, “how long will it take?”), for communication and persuasion (“it’s more fun when we work on this together”, “let me show you why I’m right!”), and for connection and structuring (“that can’t be right, it goes against all I know!”, “ah, that makes sense because …”). (via Kathy Sierra)
  3. Survey of Academic Field Experiences (PLoSone) — Our survey revealed that conducting research in the field exposes scientists to a number of negative experiences as targets and as bystanders. The experiences described by our respondents ranged from inadvertent alienating behavior, to unwanted verbal and physical sexual advances, to, most troublingly, sexual assault including rape. is immediately followed by These proportions of respondents experiencing harassment are generally consistent with other studies of workplace harassment in other professional settings. This will change when men’s behaviour and expectations change. Male readers, do your part: don’t harass and don’t tolerate it. This message brought to you from future generations who will wonder how the hell we turned a blind eye to it.
  4. sentry (github) — a realtime, platform-agnostic error logging and aggregation platform. It specializes in monitoring errors and extracting all the information needed to do a proper post-mortem without any of the hassle of the standard user feedback loop.

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.'”

Educate Users, Hardware by the Numbers, Humans Beating Computers, Hadoop's Uncomfortable Fit

  1. How to Educate Users (Luke Wroblewski) — help new users in your app, not in a video.
  2. Hardware By The Numbers (Renee DiResta) — slides from her keynote at the Solid conference. The mean success rate across all sectors is 19.8%. On average, only 10% of hardware startups raise a second round.
  3. Humans Beating Computers (Wired) — Newman assembled a small team that became known as the “Air Divers”–the people who would dive deep into the individual complaints and surface with answers. Each was given a couple hundred support tickets connected to a specific issue that the data had identified as a hot-button topic. They would go off and read through each one, then come back and propose a fix. And in the end, this is what turned the situation around. Sometimes it’s easier to put people on the job than try to code the data analysis.
  4. Hadoop’s Uncomfortable Fit in HPCHadoop is being taken seriously only at a subset of supercomputing facilities in the US, and at a finer granularity, only by a subset of professionals within the HPC community.
