ENTRIES TAGGED "statistics"
R GUI, Drone Regulations, Bitcoin Stats, and Android/iOS Money Shootout
- Deducer — An R Graphical User Interface (GUI) for Everyone.
- Integration of Civil Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) Roadmap (PDF, FAA) — first pass at regulatory framework for drones. (via Anil Dash)
- Bitcoin Stats — $21MM traded, $15MM of electricity spent mining. Goodness. (via Steve Klabnik)
- iOS vs Android Numbers (Luke Wroblewski) — roundup comparing Android to iOS in recent commerce writeups. More Android handsets, but less revenue per download/impression/etc.
Warrant Canary, Polluted Statistics, Dollars for Deathbots, and Protocol Madness
- Apple Transparency Report (PDF) — contains a warrant canary, the statement Apple has never received an order under Section 215 of the USA Patriot Act. We would expect to challenge an order if served on us which will of course be removed if one of the secret orders is received. Bravo, Apple, for implementing a clever hack to route around excessive secrecy. (via Boing Boing)
- You’re Probably Polluting Your Statistics More Than You Think — it is insanely easy to find phantom correlations in random data without obviously being foolish. Anyone who thinks it’s possible to draw truthful conclusions from data analysis without really learning statistics needs to read this. (via Stijn Debrouwere)
- CyPhy Funded (Quartz) — the second act of iRobot co-founder Helen Greiner, maker of the famed Roomba robot vacuum cleaner. She terrified ETech long ago—the audience were expecting Roomba cuteness and got a keynote about military deathbots. It would appear she’s still in the deathbot niche, not so much with the cute. Remember this when you build your OpenCV-powered recoil-resistant load-bearing-hoverbot and think it’ll only ever be used for the intended purpose of launching fertiliser pellets into third world hemp farms.
- User-Agent String History — a light-hearted illustration of why the formal semantic value of free-text fields is driven to zero in the face of actual use.
- Android Guides — lots of info on coding for Android.
- Statistics Done Wrong — learn from these failure modes. Not medians or means. Modes.
- Streaming, Sketching, and Sufficient Statistics (YouTube) — how to process huge data sets as they stream past your CPU (e.g., those produced by sensors). (via Ben Lorica)
Publishing Bad Research, Reproducing Research, DIY Police Scanner, and Inventing the Future
- Science Not as Self-Correcting As It Thinks (Economist) — REALLY good discussion of the shortcomings in statistical practice by scientists, peer-review failures, and the complexities of experimental procedure and fuzziness of what reproducibility might actually mean.
- Reproducibility Initiative Receives Grant to Validate Landmark Cancer Studies — The key experimental findings from each cancer study will be replicated by experts from the Science Exchange network according to best practices for replication established by the Center for Open Science through the Center’s Open Science Framework, and the impact of the replications will be tracked on Mendeley’s research analytics platform. All of the ultimate publications and data will be freely available online, providing the first publicly available complete dataset of replicated biomedical research and representing a major advancement in the study of reproducibility of research.
- $20 SDR Police Scanner — using software-defined radio to listen to the police band.
- Reimagine the Chemistry Set — $50k prize in contest to design a “chemistry set” type kit that will engage kids as young as 8 and inspire people who are 88. We’re looking for ideas that encourage kids to explore, create, build and question. We’re looking for ideas that honor kids’ curiosity about how things work. Backed by the Moore Foundation and Society for Science and the Public.
Distrusting CA Certs, Brain Talk, Ineffective Interventions, and Visual A/B Tools
- Reducing the Roots of Some Evil (Etsy) — Based on our first two months of data we have removed a number of unused CA certificates from some pilot systems to test the effects, and will run CAWatch for a full six months to build up a more comprehensive view of what CAs are in active use. Sign of how broken the CA system for SSL is. (via Alex Dong)
- Mind the Brain — PLOS podcast interviews Sci Foo alum and delicious neuroscience brain of awesome, Vaughan Bell. (via Fabiana Kubke)
- How Often are Ineffective Interventions Still Used in Practice? (PLOSone) — tl;dr: 8% of the time. Imagine the number if you asked how often ineffective software development practices are still used.
- Announcing Evan’s Awesome A/B Tools — I am calling these tools awesome because they are intuitive, visual, and easy-to-use. Unlike other online statistical calculators you’ve probably seen, they’ll help you understand what’s going on “under the hood” of common statistical tests, and by providing ample visual context, they make it easy for you to explain p-values and confidence intervals to your boss. (And they’re free!)
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.
Enlightened Tinkering, In-Browser Tor Proxy, Dark Patterns, and Subjective Data
- Hands on Learning (HuffPo) — Unfortunately, engaged and enlightened tinkering is disappearing from contemporary American childhood. (via BoingBoing)
- Dark Patterns (Slideshare) — User interfaces to trick people. (via Beta Knowledge)
- Bill Gates is Naive: Data Are Not Objective (Math Babe) — examples at the end of biased models/data should be on the wall of everyone analyzing data. (via Karl Fisch)
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.
Faking with Stats, Praising Coworkers, Medium Explained, and SIGGraph Trailer
- Statistical Misdirection Master Class — examples from Fox News. The further through the list you go, the more horrifying^Wedifying they are. Some are clearly classics from the literature, but some are (as far as I can tell) newly developed graphical “persuasion” techniques.
- Wall of Awesome — give your coworkers some love.
- Dave Winer on Medium — Dave hits some interesting points: Users can create new buckets or collections and call them anything they want. A bucket is analogous to a blog post. Then other people can post to it. That’s like a comment. But it doesn’t look like a comment. It’s got a place for a big image at the top. It looks much prettier than a comment, and much bigger. Looks are important here.
- SIGGraph Asia Trailer (YouTube) — resuiting Sims and rotating city blocks, at the end, were my favourite. (via Andy Baio)
- 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.
