Insecure Hardware, Doc Database, Kids Programming, and Ad-Blocking AP
- Researchers Can Slip an Undetectable Trojan into Intel’s Ivy Bridge CPUs (Ars Technica) — The exploit works by severely reducing the amount of entropy the RNG normally uses, from 128 bits to 32 bits. The hack is similar to stacking a deck of cards during a game of Bridge. Keys generated with an altered chip would be so predictable an adversary could guess them with little time or effort required. The severely weakened RNG isn’t detected by any of the “Built-In Self-Tests” required for the P800-90 and FIPS 140-2 compliance certifications mandated by the National Institute of Standards and Technology.
- rethinkdb — open-source distributed JSON document database with a pleasant and powerful query language.
- Teach Kids Programming — a collection of resources. I start on Scratch much sooner, and 12+ definitely need the Arduino, but generally I agree with the things I recognise, and have a few to research …
- Raspberry Pi as Ad-Blocking Access Point (AdaFruit) — functionality sadly lacking from my off-the-shelf AP.
Remote Work, Raspberry Pi Code Machine, Low-Latency Data Processing, and Probabilistic Table Parsing
- Fog Creek’s Remote Work Policy — In the absence of new information, the assumption is that you’re producing. When you step outside the HQ work environment, you should flip that burden of proof. The burden is on you to show that you’re being productive. Is that because we don’t trust you? No. It’s because a few normal ways of staying involved (face time, informal chats, lunch) have been removed.
- MillWheel (PDF) — a framework for building low-latency data-processing applications that is widely used at Google. Users specify a directed computation graph and application code for individual nodes, and the system manages persistent state and the continuous ﬂow of records, all within the envelope of the framework’s fault-tolerance guarantees. From Google Research.
- Probabilistic Scraping of Plain Text Tables — the method leverages topological understanding of tables, encodes it declaratively into a mixed integer/linear program, and integrates weak probabilistic signals to classify the whole table in one go (at sub second speeds). This method can be used for any kind of classification where you have strong logical constraints but noisy data.
The Contract, Fixing Signin, Pi Gaming, and Glitchy Marketing Constructs
- The Unengageables (Dan Meyer) — They signed their “didactic contract” years and years ago. They signed it. Their math teachers signed it. The agreement says that the teacher comes into class, tells them what they’re going to learn, and shows them three examples of it. In return, the students take what their teacher showed them and reproduce it twenty times before leaving class. Then they go home with an assignment to reproduce it twenty more times. Then here you come, Ms. I-Just-Got-Back-From-A-Workshop, and you want to change the agreement? Yeah, you’ll hear from their attorney. Applies to management as much as to teaching.
- Fixing Signin — The general principle can be stated simply, in two parts: first, give users a trust-worthy way to identify themselves. Second, do so with as little information as possible, because users don’t want to (and simply can’t) remember things like passwords in a secure way. (via Tim Bray)
- Retro Gaming with Raspberry Pi (Adafruit) — finally, a clear incentive for kids to work through the frustration of setting up their own Linux box.
- Mieko Haire — Apple’s fictious demo lady. Or is she fictitious? This is a new aesthetic-esque glitch, but while most glitches are glitches because you see something that doesn’t exist, this is glitchy because the fictions are actual people. Ok, maybe I need to lay off the peyote.
Geeky Primer, Visible CSS, Remote Working, and Raspberry Pi Sentiment Server

- Visible CSS Rules — Enter a url to see how the css rules interact with that page.
- How to Work Remotely — none of this is rocket science, it’s all true and things we had to learn the hard way.

Raspberry Pi MITM, Industrial Robot SDK, Cheap Mill, and Open Source State Replication in Go
- Raspberry Pi Wireless Attack Toolkit — A collection of pre-configured or automatically-configured tools that automate and ease the process of creating robust Man-in-the-middle attacks. The toolkit allows your to easily select between several attack modes and is specifically designed to be easily extendable with custom payloads, tools, and attacks. The cornerstone of this project is the ability to inject Browser Exploitation Framework Hooks into a web browser without any warnings, alarms, or alerts to the user. We accomplish this objective mainly through wireless attacks, but also have a limpet mine mode with ettercap and a few other tricks.
- Industrial Robot with SDK For Researchers (IEEE Spectrum) — $22,000 industrial robot with 7 degrees-of-freedom arms, integrated cameras, sonar, and torque sensors on every joint. [...] The Baxter research version is still running a core software system that is proprietary, not open. But on top of that the company built the SDK layer, based on ROS (Robot Operation System), and this layer is open source. In addition, there are also some libraries of low level tasks (such as joint control and positioning) that Rethink made open.
- OtherMill (Kickstarter) — An easy to use, affordable, computer controlled mill. Take all your DIY projects further with custom circuits and precision machining. (via Mike Loukides)

Email Triage, Pulse Detection, Big Building Data, and Raspberryduino Ardpi
- Triage — iPhone app to quickly triage your email in your downtime. See also the backstory. Awesome UI.
- Webcam Pulse Detector — I was wondering how long it would take someone to do the Eulerian video magnification in real code. Now I’m wondering how long it will take the patent-inspired takedown…
- How Microsoft Quietly Built the City of the Future — The team now collects 500 million data transactions every 24 hours, and the smart buildings software presents engineers with prioritized lists of misbehaving equipment. Algorithms can balance out the cost of a fix in terms of money and energy being wasted with other factors such as how much impact fixing it will have on employees who work in that building. Because of that kind of analysis, a lower-cost problem in a research lab with critical operations may rank higher priority-wise than a higher-cost fix that directly affects few. Almost half of the issues the system identifies can be corrected in under a minute, Smith says.
- UDOO (Kickstarter) — mini PC that could run either Android or Linux, with an Arduino-compatible board embedded. Like faster Raspberry Pi but with Arduino Due-compatible I/O.
Free Books, Analytics Goofs, Book Boilerplate, and Learn CS with the Raspberry Pi
- Free Book Sifter — lists all the free books on Amazon, has RSS feeds and newsletters. (via BoingBoing)
- Whom the Gods Would Destroy, They First Give Realtime Analytics — a few key reasons why truly real-time analytics can open the door to a new type of (realtime!) bad decision making. [U]ser demographics could be different day over day. Or very likely, you could see a major difference in user behavior immediately upon releasing a change, only to watch it evaporate as users learn to use new functionality. Given all of these concerns, the conservative and reasonable stance is to only consider tests that last a few days or more.
- Web Book Boilerplate (Github) — uses plain old markdown and generates a well structured HTML version of your written words. Since it’s sitting on top of Pandoc and Grunt, you can easily make your books available for every platform. MIT-style license.
- Raspberry Pi Education Manual (PDF) — from Scratch to Python and HCI all via the Raspberry Pi. Intended to be informative and a series of lessons for teachers and students learning coding with the Raspberry Pi as their first device.
It's iPad evolution rather than revolution, increasing patent penalties for Android, and Raspberry Pi is served.
Apple unveils pretty much what it was expected to unveil, and decides to treat Android as a cash cow rather than an enemy. Meanwhile, the Raspberry Pi is finally out, so let the hacking begin.
Flex goes FLOSS, some cheap Pi, and brain on a chip.
Adobe just gave away Flex, a new single-board computer might dethrone Arduino as the tool of choice for makers, and researchers bring us a step closer to our robotic overlords.
