Repurposing Dead Retail Space, Open Standards, Space Copyright, and Bridging Lessons
- Ubiquity — Sears Holdings has formed a new unit to market space from former Sears and Kmart retail stores as a home for data centers, disaster recovery space and wireless towers.
- Google Abandons Open Standards for Instant Messaging (EFF) — it has to be a sign of the value to users of open standards that small companies embrace them and large companies reject them.
- How Does Copyright Work in Space? (The Economist) — amazingly complex rights trail for the International Space Station-recorded cover of “Space Oddity”. Sample: Commander Hadfield and his son Evan spent several months hammering out details with Mr Bowie’s representatives, and with NASA, Russia’s space agency ROSCOSMOS and the CSA. That’s the SIMPLE HAPPY ENDING.
- Great Lessons: Evan Weinberg’s “Do You Know Blue?” (Dan Meyer) — It’s a bridge from math to computer science. Students get a chance to write algorithms in a language understood by both mathematicians and the computer scientists. It’s analogous to the Netflix Prize for grown-up computer scientists.
Exploiting Glass, Teaching Probability, Product Design, and Subgraph Matching
- Exploiting a Bug in Google Glass — unbelievably detailed and yet easy-to-follow explanation of how the bug works, how the author found it, and how you can exploit it too. The second guide was slightly more technical, so when he returned a little later I asked him about the Debug Mode option. The reaction was interesting: he kind of looked at me, somewhat confused, and asked “wait, what version of the software does it report in Settings”? When I told him “XE4″ he clarified “XE4, not XE3″, which I verified. He had thought this feature had been removed from the production units.
- Probability Through Problems — motivating problems to hook students on probability questions, structured to cover high-school probability material.
- Connbox — love the section “The importance of legible products” where the physical UI interacts seamless with the digital device … it’s glorious. Three amazing videos.
- The Index-Based Subgraph Matching Algorithm (ISMA): Fast Subgraph Enumeration in Large Networks Using Optimized Search Trees (PLoSONE) — The central question in all these fields is to understand behavior at the level of the whole system from the topology of interactions between its individual constituents. In this respect, the existence of network motifs, small subgraph patterns which occur more often in a network than expected by chance, has turned out to be one of the defining properties of real-world complex networks, in particular biological networks. [...] An implementation of ISMA in Java is freely available.
Analytics vs Learning, Reproducible Science, Ramping up Military Internet Attacks, and Compressed Sensing
- Analytics for Learning — Since doing good learning analytics is hard, we often do easy learning analytics and pretend that they are good instead. But pretending doesn’t make it so. (via Dan Meyer)
- Reproducible Research — a list of links to related work about reproducible research, reproducible research papers, etc. (via Stijn Debrouwere)
- Pentagon Deploying 100+ Cyber Teams — The organization defending military networks — cyber protection forces — will comprise more than 60 teams, a Pentagon official said. The other two organizations — combat mission forces and national mission forces — will conduct offensive operations. I’ll repeat that: offensive operations.
- Towards Deterministic Compressed Sensing (PDF) — instead of taking lots of data, compressing by throwing some away, can we only take a few samples and reconstruct the original from that? (more mathematically sound than my handwaving explanation). See also Compressed sensing and big data from the Practical Quant. (via Ben Lorica)
Inside the Aaron Swartz Investigation, Multivariate Dataset Exploration, Augmediated Life, and Public Experience
- Life Inside the Aaron Swartz Investigation — do hard things and risk failure. What else are we on this earth for?
- Steve Mann: My Augmediated Life (IEEE) — Until recently, most people tended to regard me and my work with mild curiosity and bemusement. Nobody really thought much about what this technology might mean for society at large. But increasingly, smartphone owners are using various sorts of augmented-reality apps. And just about all mobile-phone users have helped to make video and audio recording capabilities pervasive. Our laws and culture haven’t even caught up with that. Imagine if hundreds of thousands, maybe millions, of people had video cameras constantly poised on their heads. If that happens, my experiences should take on new relevance.
- The Google Glass Feature No-One Is Talking About — The most important Google Glass experience is not the user experience – it’s the experience of everyone else. The experience of being a citizen, in public, is about to change.
SCADA 0-Day, Complexity Course, ToS Tracking, and Custom Manufacturing Prostheses
- Tridium Niagara (Wired) — A critical vulnerability discovered in an industrial control system used widely by the military, hospitals and others would allow attackers to remotely control electronic door locks, lighting systems, elevators, electricity and boiler systems, video surveillance cameras, alarms and other critical building facilities, say two security researchers. cf the SANS SCADA conference.
- Santa Fe Institute Course: Introduction to Complexity — 11 week course on understanding complex systems: dynamics, chaos, fractals, information theory, self-organization, agent-based modeling, and networks. (via BoingBoing)
- Terms of Service Changes — a site that tracks changes to terms of service. (via Andy Baio)
- 3D Printing a Replacement Hand for a 5 Year Old Boy (Ars Technica) — the designs are on Thingiverse. For more, see their blog.
SSH/L Multiplexer, GitHub Bots, Test Your Assumptions, and Tech Trends
- sslh — ssh/ssl multiplexer.
- Github Says No to Bots (Wired) — what’s interesting is that bots augmenting photos is awesome in Flickr: take a photo of the sky and you’ll find your photo annotated with stars and whatnot. What can GitHub learn from Flickr?
- Four Assumptions of Multiple Regression That Researchers Should Always Test — “but I found the answer I wanted! What do you mean, it might be wrong?!”
- Tenth Grade Tech Trends (Medium) — if you want to know what will have mass success, talk to early adopters in the mass market. We alpha geeks aren’t that any more.
Win95 Tips, Obama's Big Data, Aggregate Statistics, and Foxconn Robots
- Windows 95 Tips — hilarious tumblr showing the dark side of life through Windows 95 UI tips. (via Juha Saarinen)
- Everything We Know About Obama’s Big Data Operation (Pro Publica) — “White suburban women? They’re not all the same. The Latino community is very diverse with very different interests,” Dan Wagner, the campaign’s chief analytics officer, told The Los Angeles Times. “What the data permits you to do is figure out that diversity.”
- cube (GitHub) — time-series data collection and analysis. Cube lets you compute aggregate statistics post hoc. It also enables richer analysis, such as quantiles and histograms of arbitrary event sets. Cube is built on MongoDB and available under the Apache License on GitHub.
- 1M Robots to Replace 1M Human Jobs at Foxconn (Singularity Hub) — Foxconn plant opening, making manufacturing robots, and they appear to be dogfooding by using them in other plants. $25k each, 10k+ made, and fits into the pattern: the number of operational robots in China increased by 42 percent from 2010 to 2011.
- An Intuitive Guide to Linear Algebra — Here’s the linear algebra introduction I wish I had. I wish I’d had it, too. (via Hacker News)
- Think Bayes — an introduction to Bayesian statistics using computational methods.
- Divshot — a startup turning mockups into web apps, built on top of the Bootstrap front-end framework. I feel momentum and a tipping point approaching, where building things on the web is about to get easier again (the way it did with Ruby on Rails). cf Jetstrap.
ID-based Democracy, Web Documentation, American Telco Gouging, and Stats Cookbook
- Finland Crowdsourcing New Laws (GigaOm) — online referenda. The Finnish government enabled something called a “citizens’ initiative”, through which registered voters can come up with new laws – if they can get 50,000 of their fellow citizens to back them up within six months, then the Eduskunta (the Finnish parliament) is forced to vote on the proposal. Now this crowdsourced law-making system is about to go online through a platform called the Open Ministry. Petitions and online voting are notoriously prone to fraud, so it will be interesting to see how well the online identity system behind this holds up.
- WebPlatform — wiki of information about developing for the open web. Joint production of many of the $BIGCOs of the web and the W3C, so will be interesting to see, as it develops, whether it has the best aspects of each or the worst.
- Why Your Phone, Cable, Internet Bills Cost So Much (Yahoo) — “The companies essentially have a business model that is antithetical to economic growth,” he says. “Profits go up if they can provide slow Internet at super high prices.” Excellent piece!
- Probability and Statistics Cookbook (Matthias Vallentin) — The cookbook contains a succinct representation of various topics in probability theory and statistics. It provides a comprehensive reference reduced to the mathematical essence, rather than aiming for elaborate explanations. CC-BY-NC-SA licensed, LaTeX source on github.
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.
