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.

Technical Debt, A/A Testing, NSA's Latest, and John von Neumann

  1. Pycon 2015: Technical Debt, The Monster in Your Closet (YouTube) — excellent talk from PyCon. See also slides.
  2. A/A TestingIn an A/A test, you run a test using the exact same options for both “variants” in your test. That’s right, there’s no difference between “A” and “B” in an A/A test. It sounds stupid, until you see the “results.” (via Nelson Minar)
  3. NSA Declares War on General-Purpose Computing (BoingBoing) — NSA director Michael S Rogers says his agency wants “front doors” to all cryptography used in the USA, so that no one can have secrets it can’t spy on — but what he really means is that he wants to be in charge of which software can run on any general purpose computer.
  4. John von Neumann Documentary (YouTube) — 1966 documentary from the American Mathematical Association on the father of digital computing, who also is hailed as the father of game theory and much much more. (via Paul Walker)

Philosophical Research, Reading Turing, Security Exercises, and Golang Madness

  1. The Trolley and the PsychopathNot only does a “utilitarian” response (“just kill the fat guy”) not actually reflect a utilitarian outlook, it may actually be driven by broad antisocial tendencies, such as lowered empathy and a reduced aversion to causing someone harm. Questionably expanding scope of claims in the behavioural philosophy research. (via Ed Yong)
  2. Summary of Computing Machinery and Intelligence (1950) by Alan Turing (Jack Hoy) — still interesting and relevant today. cf Why Aren’t We Reading Turing
  3. Exploit Exercisesa variety of virtual machines, documentation, and challenges that can be used to learn about a variety of computer security issues, such as privilege escalation, vulnerability analysis, exploit development, debugging, reverse engineering, and general cyber security issues.
  4. GopherJS — golang to Javascript compiler so you can experience the ease of typed compiled languages in the security and stability of the browser platform.

Welfare and Entrepreneurialism, Infrastructure Secrets, Insectoid Robots, Hacking Hexbugs

  1. Welfare Makes America More Entrepreneurial (The Atlantic) — In a 2014 paper, Olds examined the link between entrepreneurship and food stamps, and found that the expansion of the program in some states in the early 2000s increased the chance that newly eligible households would own an incorporated business by 16%. (Incorporated firms are a better proxy for job-creating startups than unincorporated ones.)
  2. Security of Infrastructure Secrets — everything has a key that’s just one compromise or accidental drop away.
  3. Festo’s Fantastical Insectoid Robots Include Bionic Ants and Butterflies (IEEE) — Each butterfly has a 50-centimeter wingspan and weighs just 32 grams, but carries along two servo motors to independently actuate the wings, an IMU, accelerometer, gyro, and compass, along with two tiny 90-mAh lithium-polymer batteries. With a wing beat frequency of between one and two flaps per second, top speed is 2.5 m/s, with a flight time of three to four minutes before needing a 15-minute charge. The wings themselves use impossibly thin carbon rods for structure, and are covered with an even thinner elastic capacitor film.
  4. Arduino Celebration and Hexbugs hacking with Bob Martin (SparkFun) — The Hunter demo is a combination of object detection and object avoidance. It uses an IR sensor array to determine objects around it. Objects that appear and then disappear quickly, say in a second or two are targets which it will walk towards; however, a target that stays constant will be avoided. I’m still trying to find the perfect balance between making a decision between fleeing prey and a wall using only simple proximity samples from an IR detector array.

What the IoT can learn from the health care industry

Federated authentication and authorization could provide security solutions for the Internet of Things.

Adrian Gropper co-authored this post.

Nyckel_erik_forsberg_FlickrAfter a short period of excitement and rosy prospects in the movement we’ve come to call the Internet of Things (IoT), designers are coming to realize that it will survive or implode around the twin issues of security and user control: a few electrical failures could scare people away for decades, while a nagging sense that someone is exploiting our data without our consent could sour our enthusiasm. Early indicators already point to a heightened level of scrutiny — Senator Ed Markey’s office, for example, recently put the automobile industry under the microscope for computer and network security.

In this context, what can the IoT draw from well-established technologies in federated trust? Federated trust in technologies as diverse as the Kerberos and SAML has allowed large groups of users to collaborate securely, never having to share passwords with people they don’t trust. OpenID was probably the first truly mass-market application of federated trust.

OpenID and OAuth, which have proven their value on the Web, have an equally vital role in the exchange of data in health care. This task — often cast as the interoperability of electronic health records — can reasonably be described as the primary challenge facing the health care industry today, at least in the IT space. Reformers across the health care industry (and even Congress) have pressured the federal government to make data exchange the top priority, and the Office of the National Coordinator for Health Information Technology has declared it the centerpiece of upcoming regulations.

Sad Sysadminning, Data Workflow, Ambiguous "Database," and Creepy Barbie

  1. The Sad State of Sysadmin in the Age of Containers (Erich Schubert) — a Grumpy Old Man rant, but solid. And since nobody is still able to compile things from scratch, everybody just downloads precompiled binaries from random websites. Often without any authentication or signature.
  2. Pinball — Pinterest open-sourced their data workflow manager.
  3. Disambiguating Databases (ACM) — The scope of the term database is vast. Technically speaking, anything that stores data for later retrieval is a database. Even by that broad definition, there is functionality that is common to most databases. This article enumerates those features at a high level. The intent is to provide readers with a toolset with which they might evaluate databases on their relative merits.
  4. Hello Barbie — I just can’t imagine a business not wanting to mine and repurpose the streams of audio data coming into their servers. “You listen to Katy Perry a lot. So do I! You have a birthday coming up. Have you told your parents about the Katy Perry brand official action figurines from Mattel? Kids love ‘em, and demo data and representative testing indicates you will, too!” Or just offer a subscription service where parents can listen in on what their kids say when they play in the other room with their friends. Or identify product mentions and cross-market offline. Or …

Go Microservices, Watch Experience, Multithreading Bugs, and Spooks Ahoy

  1. Microservices in Go — tale of rewriting a Ruby monolith as Go microservices. Interesting, though being delivered at Gophercon India suggests the ending is probably not unhappy.
  2. Watch & Wear (John Cross Neumann) — Android watch as predictor of the value and experience of an Apple Watch. I believe this is the true sweet spot for meaningful wearable experiences. Information that matters to you in the moment, but requires no intervention. Wear actually does this extremely well through Google Now. Traffic, Time to Home, Reminders, Friend’s Birthdays, and Travel Information all work beautifully. […] After some real experience with Wear, I think what is more important is to consider what Apple Watch is missing: Google Services. Google Services are a big component of what can make wearing a tiny screen on your wrist meaningful and personal. I wouldn’t be surprised after the initial wave of apps through the app store if Google Now ends up being the killer app for Apple Watch.
  3. Solving 11 Likely Problems In Your Multithreaded Code (Joe Duffy) — a good breakdown of concurrency problems, including lower-level ones than high-level languages expose. But beware. If you try this [accessing variables with synchronisation] on a misaligned memory location, or a location that isn’t naturally sized, you can encounter a read or write tearing. Tearing occurs because reading or writing such locations actually involves multiple physical memory operations. Concurrent updates can happen in between these, potentially causing the resultant value to be some blend of the before and after values.
  4. Obama Sharply Criticizes China’s Plans for New Technology Rules (Reuters) — In an interview with Reuters, Obama said he was concerned about Beijing’s plans for a far-reaching counterterrorism law that would require technology firms to hand over encryption keys, the passcodes that help protect data, and install security “backdoors” in their systems to give Chinese authorities surveillance access. Goose sauce is NOT gander sauce! NOT! Mmm, delicious spook sauce.

Wearable Warning, Time Series Data, App Cards, and Secure Comms

  1. You Guys Realize the Apple Watch is Going to Flop, Right? — leaving aside the “guys” assumption of its readers, you can take this either as a list of the challenges Apple will inevitably overcome or bypass when they release their watch, or (as intended) a list of the many reasons that it’s too damn soon for watches to be useful. The Apple Watch is Jonathan Ive’s new Newton. It’s a potentially promising form that’s being built about 10 years before Apple has the technology or infrastructure to pull it off in a meaningful way. As a result, the novel interactions that could have made the Apple watch a must-have device aren’t in the company’s launch product, nor are they on the immediate horizon. And all Apple can sell the public on is a few tweets and emails on their wrists—an attempt at a fashion statement that needs to be charged once or more a day.
  2. InfluxDB, Now With Tags and More UnicornsThe combination of these new features [tagging, and the use of tags in queries] makes InfluxDB not just a time series database, but also a database for time series discovery. It’s our solution for making the problem of dealing with hundreds of thousands or millions of time series tractable.
  3. The End of Apps as We Know ThemIt may be very likely that the primary interface for interacting with apps will not be the app itself. The app is primarily a publishing tool. The number one way people use your app is through this notification layer, or aggregated card stream. Not by opening the app itself. To which one grumpy O’Reilly editor replied, “cards are the new walled garden.”
  4. Signal 2.0Signal uses your existing phone number and address book. There are no separate logins, usernames, passwords, or PINs to manage or lose. We cannot hear your conversations or see your messages, and no one else can either. Everything in Signal is always end-to-end encrypted, and painstakingly engineered in order to keep your communication safe.

No Estimates, Brand Advertising, Artificial Intelligence, and GPG BeGone

  1. #NoEstimatesAllspaw also points out that the yearning to break the bonds of estimation is nothing new — he’s fond of quoting a passage from The Unwritten Laws of Engineering, a 1944 manual which says that engineers “habitually try to dodge the irksome responsibility for making commitments.” All of Allspaw’s segment is genius.
  2. Old Fashioned Snapchatget a few drinks in any brand advertiser and they’ll admit that the number one reason they know that brand advertising works is that, if they stop, sales inevitably drop.
  3. Q&A With Bruce Sterling on Artificial Intelligence — in which Sterling sounds intelligent, and the questioner sounds Artificial.
  4. GPG and Me (Moxie Marlinspike) — Even though GPG has been around for almost 20 years, there are only ~50,000 keys in the “strong set,” and less than 4 million keys have ever been published to the SKS keyserver pool ever. By today’s standards, that’s a shockingly small user base for a month of activity, much less 20 years. This was a great talk at Webstock this year.

Bricking Cars, Mapping Epigenome, Machine Learning from Encrypted Data, and Phone Privacy

  1. Remotely Bricking Cars (BoingBoing) — story from 2010 where an intruder illegally accessed Texas Auto Center’s Web-based remote vehicle immobilization system and one by one began turning off their customers’ cars throughout the city.
  2. Beginning to Map the Human Epigenome (MIT) — Kellis and his colleagues report 111 reference human epigenomes and study their regulatory circuitry, in a bid to understand their role in human traits and diseases. (The paper itself.)
  3. Machine Learning Classification over Encrypted Data (PDF) — It is worth mentioning that our work on privacy-preserving classification is complementary to work on differential privacy in the machine learning community. Our work aims to hide each user’s input data to the classification phase, whereas differential privacy seeks to construct classifiers/models from sensitive user training data that leak a bounded amount of information about each individual in the training data set. See also The Morning Paper’s unpacking of it.
  4. Privacy of Phone Audio (Reddit) — unconfirmed report from Redditor I started a new job today with Walk N’Talk Technologies. I get to listen to sound bites and rate how the text matches up with what is said in an audio clip and give feed back on what should be improved. At first, I though these sound bites were completely random. Then I began to notice a pattern. Soon, I realized that I was hearing peoples commands given to their mobile devices. Guys, I’m telling you, if you’ve said it to your phone, it’s been recorded…and there’s a damn good chance a 3rd party is going to hear it.
