Vanishing Money, Car Hackery, Data Literacy Course, and Cheaper CI
- The Programming Error That Cost Mt Gox 2609 Bitcoins — in the unforgiving world of crypto-currency, it’s easy to miscode and vanish your money.
- Ford Invites Open-Source Community to Tinker Away — One example: Nelson has re-tasked the motor from a Microsoft Xbox 360 game controller to create an OpenXC shift knob that vibrates to signal gear shifts in a standard-transmission Mustang. The 3D-printed prototype shift knob uses Ford’s OpenXC research platform to link devices to the car via Bluetooth, and shares vehicle data from the on-board diagnostics port. Nelson has tested his prototype in a Ford Mustang Shelby GT500 that vibrates at the optimal time to shift.
- Making Sense of Data — Google online course on data literacy.
- Cost-Efficient Continuous Integration at Mozilla — CI on a big project can imply hundreds if not thousands of VMs on Amazon spinning up to handle compiles and tests. This blog post talks about Mozilla’s efforts to reduce its CI-induced spend without reducing the effectiveness of its CI practices.
Flying Robot, State of Cyberspace, H.264, and Principal Component Analysis
- Insect-Inspired Collision-Resistant Robot — clever hack to make it stable despite bouncing off things.
- The Battle for Power on the Internet (Bruce Schneier) — the state of cyberspace. [M]ost of the time, a new technology benefits the nimble first. [...] In other words, there will be an increasing time period during which nimble distributed powers can make use of new technologies before slow institutional powers can make better use of those technologies.
- Cisco’s H.264 Good News (Brendan Eich) — Cisco is paying the license fees for a particular implementation of H.264 to be used in open source software, enabling it to be the basis of web streaming video across all browsers (even the open source ones). It’s not as ideal a solution as it might sound.
- Principal Component Analysis for Dummies — This post will give a very broad overview of PCA, describing eigenvectors and eigenvalues (which you need to know about to understand it) and showing how you can reduce the dimensions of data using PCA. As I said it’s a neat tool to use in information theory, and even though the maths is a bit complicated, you only need to get a broad idea of what’s going on to be able to use it effectively.
Digital Citizenship, Berg Cloud, Data Warehouse, and The Spying Iron
- Mozilla Web Literacy Standard — things you should be able to do if you’re to be trusted to be on the web unsupervised. (via BoingBoing)
- Berg Cloud Platform — hardware (shield), local network, and cloud glue. Caution: magic ahead!
- Shark — a large-scale data warehouse system for Spark designed to be compatible with Apache Hive. It can execute Hive QL queries up to 100 times faster than Hive without any modification to the existing data or queries. Shark supports Hive’s query language, metastore, serialization formats, and user-defined functions, providing seamless integration with existing Hive deployments and a familiar, more powerful option for new ones. (via Strata)
- The Malware of Things — a technician opening up an iron included in a batch of Chinese imports to find a “spy chip” with what he called “a little microphone”. Its correspondent said the hidden devices were mostly being used to spread viruses, by connecting to any computer within a 200m (656ft) radius which were using unprotected Wi-Fi networks.
Autocomplete, Tor Security, News Glitches, Moz Persona
- Tor Users Get Routed (PDF) — research into the security of Tor, with some of its creators as authors. Our results show that Tor users are far more susceptible to compromise than indicated by prior work.
- Glitch News — screencaps from glitches in video news.
- FC4: Persona (Tim Bray) — Mozilla Persona, reminds us just because you’re using a protocol that allows tracking avoidance, that doesn’t mean you’ll get it.
Deep Learning, Internet of ux Nightmares, Mozilla Science Lab, and Ground-Up Computing
- Weekend Reads on Deep Learning (Alex Dong) — an article and two videos unpacking “deep learning” such as multilayer neural networks.
- The Internet of Actual Things — “I have 10 reliable activations remaining,” your bulb will report via some ridiculous light-bulbs app on your phone. “Now just nine. Remember me when I’m gone.” (via Andy Baio)
- Announcing the Mozilla Science Lab (Kaitlin Thaney) — We also want to find ways of supporting and innovating with the research community – building bridges between projects, running experiments of our own, and building community. We have an initial idea of where to start, but want to start an open dialogue to figure out together how to best do that, and where we can be of most value..
- NAND to Tetris — The site contains all the software tools and project materials necessary to build a general-purpose computer system from the ground up. We also provide a set of lectures designed to support a typical course on the subject. (via Hacker News)
Mozilla Payments, Firefox Cleans Cookies, Lost: One Web Please Return to Those Who Love It, and 3D from Spaaaaace
- How We Lost the Web (Anil Dash) — excellent talk about the decreasing openness and vanishing shared culture of the web. See also David Weinberger’s transcription.
- 3D From Space Shuttle Footage? — neat idea! Filming in 3D generally requires two cameras that are separated laterally, to create the parallax effected needed for stereoscopic vision. Fortunately, videos shot from Earth orbit can be converted to 3D without a second camera, because the camera is constantly in motion.
Titan Improved, Security Tweeps, Probabilistic Programming, and 3D-Printable Optics
- Titan 0.3 Out — graph database now has full-text, geo, and numeric-range index backends.
- Mozilla Security Community Do a Reddit AMA — if you wanted a list of sharp web security people to follow on Twitter, you could do a lot worse than this.
- Probabilistic Programming and Bayesian Methods for Hackers (Github) — An introduction to Bayesian methods + probabilistic programming in data analysis with a computation/understanding-first, mathematics-second point of view. All in pure Python. See also Why Probabilistic Programming Matters and Trends to Watch: Logic and Probabilistic Programming. (via Mike Loukides and Renee DiRestra)
- Open Source 3D-Printable Optics Equipment (PLOSone) — This study demonstrates an open-source optical library, which significantly reduces the costs associated with much optical equipment, while also enabling relatively easily adapted customizable designs. The cost reductions in general are over 97%, with some components representing only 1% of the current commercial investment for optical products of similar function. The results of this study make its clear that this method of scientific hardware development enables a much broader audience to participate in optical experimentation both as research and teaching platforms than previous proprietary methods.
Mobile Content, Google Math, Mobile Linux, and Mozilla's Strategy
- Mobile Content Strategy — Mobile is a catalyst that can help you make your content tighter without loss of clarity or information. If you make your content work well on mobile, it will work everywhere. Excellent presentation, one I want to thump on every decision-maker’s desk and say “THIS!”.
- Math at Google (PDF) — presentation showing the different types of math used to build Google. Good as overview, and as way to motivate highschool and college kids to do their math homework. “See, it really is useful! Really!” (via Ben Lorica)
- Tizen 2.0 Alpha Released — Tizen is the Linux Foundation’s mobile Linux kernel, device drivers, middleware subsystems, and Web APIs. (via The Linux Foundation)
- Explaining WebMaker Crisply (Mark Surman) — if you’ve wondered wtf Mozilla is up to, this is excellent. Mozilla has big priorities right now: the web on the desktop; the web on mobile; and web literacy.
Mozilla Single Sign-On, Designed Technology, Identifying Crackpots, and Web Page Design
- Mozilla Persona — single sign-on for the web.
- Interview with Alan Kay (Dr Dobbs Journal) — The Internet was done so well that most people think of it as a natural resource like the Pacific Ocean, rather than something that was man-made. When was the last time a technology with a scale like that was so error-free? The Web, in comparison, is a joke. The Web was done by amateurs. (via Daniel Bachhuber)
- Crackpots, Geniuses, and How to Tell The Difference (BoingBoing) — think critically, all the time. If you’re told you can’t trust any other sources of information (especially because of Big Conspiracy, or because so-and-so expert is a bad person in other areas of his or her life), be cautious. Replication is a powerful tool. It helps us get past accidental and intentional biases to see something closer to the truth. Suppressing replication is also powerful, because it leaves you with no way to check against bias.
- Properties of Intuitive Web Pages (Luke Wroblewski) — Intuitive design is how we give our users super powers. This enables them to do new things.
