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.
Open Publishing, Theatre Sensing, Reddit First, and Math Podcasts
- Open Monograph Press — an open source software platform for managing the editorial workflow required to see monographs, edited volumes and, scholarly editions through internal and external review, editing, cataloguing, production, and publication. OMP will operate, as well, as a press website with catalog, distribution, and sales capacities. (via OKFN)
- Sensing Activity in Royal Shakespeare Theatre (NLTK) — sensing activity in the theatre, for graphing. Raw data available. (via Infovore)
- Why Journalists Love Reddit (GigaOM) — “Stories appear on Reddit, then half a day later they’re on Buzzfeed and Gawker, then they’re on the Washington Post, The Guardian and the New York Times. It’s a pretty established pattern.”
- Relatively Prime: The Toolbox — Kickstarted podcasts on mathematics. (via BoingBoing)
Minecraft Devastation, Constructive Dialog, Oatmeal Rocks, and Pwning Printers
- Minecraft Experiment Devolves into Devastating Resource War — life imitates art, but artificial life imitates, well, Haiti.
- Finding Unity in the Math Wars — I recently heard a quote about constructive dialog: “Don’t argue the exact point a person made. Consider their position and respond to the best point they could have made.” I like this! (and the point that math teachers fighting with each other is missing an opportunity to fight for the existence of math education) (ps, “unity … math”, I see what you did there)
- Tesla Museum Funded — Matthew Inman, cartoonist behind The Oatmeal, used IndieGogo to raise over $850k to buy Tesla’s old building in New York and turn it into a museum. In five days. There are still 39 days to run. Impressive channeling of his audience for good.
- Printers Spontaneously Printing “SQL” Strings (Hacker News) — it’s a sign that someone’s scanning your network for vulnerable web apps, found the exposed printer port, and sent an malignant HTTP request to it.
Coffee Rings, Scaling Laws, Autonomous Aircraft, and Dreaming Computers
- The Coffee-Ring Effect (YouTube) — beautiful video of what happens in liquids as they evaporate, explaining why coffee stains are rings, and how to create liquids with even evaporative coating.
- The Importance of Quantitative Thinking Medicine (PDF) — scaling laws underly aging, metabolism, drug delivery, BMI, and more. Full of wow moments, like Fractals are a common feature of many complex systems ranging from river networks, earthquakes, and the internet to stock markets and cities. [...] Geometrically, the nested levels of continuous branching and crenulations inherent in fractallike structures optimise the transport of information, energy, and resources by maximising the surface areas across which these essential features of life flow within any volume. Because of their fractal nature, these effective surface areas are much larger than their apparent physical size. For example, even though the volume of our lungs is about 5–6 L, the total surface area of all the alveoli is almost the size of a tennis court and the total length of airways is about 2500 km. Even more striking is that if all the arteries, veins, and capillaries of an individual’s circulatory system were laid end to end, its total length would be about 100000 km, or nearly two and a half times around the earth.
- Autonomous Robotic Plane at MIT (YouTube) — hypnotic to watch it discover the room. A product of the Robust Robotics Group at MIT.
- Electric Sheep — hypnotic screensaver, where the sleeping computers collaborate on animations. You can vote up or down the animation on your screen, changing the global gene pool. Popular animations survive and propagate.
Chinese Hackers, Edible Sensors, Quantum Physics
- China Hackers Hit EU Point Man and DC (Bloomberg) — wow. The extent to which EU and US government and business computer systems have been penetrated is astonishing. Stolen information is flowing out of the networks of law firms, investment banks, oil companies, drug makers, and high technology manufacturers in such significant quantities that intelligence officials now say it could cause long-term harm to U.S. and European economies. (via Gady Epstein)
- Digestible Microchips (Nature) — The sand-particle sized sensor consists of a minute silicon chip containing trace amounts of magnesium and copper. When swallowed, it generates a slight voltage in response to digestive juices, which conveys a signal to the surface of a person’s skin where a patch then relays the information to a mobile phone belonging to a healthcare-provider. (via Sara Winge)
- Quantum Mechanics Make Simple(r) — clever way to avoid the brain pain of quantum mechanics and leap straight to the “oh!”. [N]ature is described not by probabilities (which are always nonnegative), but by numbers called amplitudes that can be positive, negative, or even complex. [...] In the usual “hierarchy of sciences”—with biology at the top, then chemistry, then physics, then math—quantum mechanics sits at a level between math and physics that I don’t know a good name for. Basically, quantum mechanics is the operating system that other physical theories run on as application software (with the exception of general relativity, which hasn’t yet been successfully ported to this particular OS). (via Hacker News)
- Selectively De-Animating Video — SIGGRAPH talk showing how to keep some things still in a video. Check out the teaser video with samples: ZOMG. I note that Maneesh Agrawala was involved: I’m a fan of his from Line Drive maps and 3D exploded views, but his entire paper list is worth reading. Wow. (via Greg Borenstein)
Randomized Trials for Policy, Crowdfunding Equity, Safe DIYBio, and Easy Unique Experiences
- Test, Learn, Adapt (PDF) — UK Cabinet Office paper on randomised trials for public policy. Ben Goldacre cowrote.
- UK EscapeTheCity Raises GBP600k in Crowd Equity — took just eight days, using the Crowdcube platform for equity-based crowd investment.
