ENTRIES TAGGED "mapping"
Disruption, Telepresence, Drone Mapping, and TV Malware
- Innovation and the Coming Shape of Social Transformation (Techonomy) — great interview with Tim O’Reilly and Max Levchin. in electronics and in our devices, we’re getting more and more a sense of how to fix things, where they break. And yet as a culture, what we have chosen to do is to make those devices more disposable, not last forever. And why do you think it will be different with people? To me one of the real risks is, yes, we get this technology of life extension, and it’s reserved for a very few, very rich people, and everybody else becomes more disposable.
- Attending a Conference via a Telepresence Robot (IEEE) — interesting idea, and I look forward to giving it a try. The mark of success for the idea, alas, is two bots facing each other having a conversation.
- Drone Imagery for OpenStreetMap — 100 acres of 4cm/pixel imagery, in less than an hour.
- LG Smart TV Phones Home with Shows and Played Files — welcome to the Internet of Manufacturer Malware.
Rich Text Editing, Structural Visualisation, DDoS Protection, Realtime DDoS Map
- Sir Trevor — nice rich-text editing. Interesting how Markdown has become the way to store formatted text without storing HTML (and thus exposing the CSRF-inducing HTML-escaping stuckfastrophe).
- Slate for Excel — visualising spreadsheet structure. I’d be surprised if it took MSFT or Goog 30 days to acquire them.
- Project Shield — Google project to protect against DDoSes.
- Digital Attack Map — DDoS attacks going on around the world. (via Jim Stogdill)
Location Data, Online Science, Mythbusting for Education, and Cheap Music For All
- Reading Runes in Animal Movement (YouTube) — accessible TEDxRiverTawe 2013 talk by Professor Rory Wilson, on his work tracking movements of animals in time and space. The value comes from high-resolution time series data: many samples/second, very granular.
- Best Science Writing Online 2012 (Amazon) — edited collection of the best blog posts on science from 2012. Some very good science writing happening online.
- Designing Effective Multimedia for Physics Education (PDF) — Derek Muller’s PhD thesis, summarised as “mythbusting beats lectures, hands down”. See also his TED@Sydney talk.
- Melomics — royalty-free computer-generated music, all genres, for sale (genius business model). Academic spinoff from Dr. Francisco J. Vico’s work at UMA in Spain.
Thread Problems, Better Image Search, Open Standards, and GitHub Maps
- Multithreading is Hard — The compiler and the processor both conspire to defeat your threads by moving your code around! Be warned and wary! You will have to do battle with both. Sample code and explanation of WTF the eieio barrier is (hint: nothing to do with Old McDonald’s server farm). (via Erik Michaels-Ober)
- Improving Photo Search (Google Research) — volume of training images, number of CPU cores, and Freebase entities. (via Alex Dong)
- Is Google Dumping Open Standards for Open Wallets? (Matt Asay) — it’s easier to ship than standardise, to innovate than integrate, but the ux of a citizen in the real world is pants. Like blog posts? Log into Facebook to read your friends! (or Google+) Chat is great, but you’d better have one client per corporation your friends hang out on. Nobody woke up this morning asking for features to make web pages only work on one browser. The user experience of isolationism is ugly.
- GitHub Renders GeoJSON — Under the hood we use Leaflet.js to render the geoJSON data, and overlay it on a custom version of MapBox’s street view baselayer — simplified so that your data can really shine. Best of all, the base map uses OpenStreetMap data, so if you find an area to improve, edit away.
Pseudo Memetics, Top Pinch or Bottom Pinch, Innovation Cartography, and Awesome Compilation Hackery
- Anatomy of Two Memes — comparing the spread of Gangnam Style to Harlem Shake. Memes are like currencies: you need to balance accessibility (or ‘money supply’) and inflation. Gangnam Style became globally accessible through top-down mainstream sources (High Popularity), but this gave it high social inflation so it wasn’t valuable to share (Low Shareability). However, scale sustained its long term growth. Harlem Shake was not as easily accessible because it was driven more by small communities (Low Popularity), but for the same reason, being less easily accessible, it remained highly valuable (High Shareability). Lack of scale was what made Harlem Shake growth short-term and eventually killed it prematurely. Caution: contains fauxconomics.
- Handedness (Github) — determine left or right handedness from pinch gesture.
- Innovation Cartography — video of a talk by Richard Jefferson of Cambia’s lens, on the imperative to innovate held at the Skoll World Forum on Social Enterprise. His story of maritime cartography (starts around 5m50s) is awesome.
- Statically Recompiling NES Games into Native Executables with LLVM and Go — or “crack for Nat” as I like to translate that title.
Know Your HTTP, Digital Exploitation, Insecure Webcams, and CS Courses
- Know Your HTTP Posters (GitHub) — A0-posters about the HTTP protocol.
- Crowdserfing — when a large corp uses crowd-sourced volunteering for its own financial gain, without giving back. It offends my sense of reciprocity as well, but nobody is coerced into using Google Maps or contributing data to it. How do we decide what is “right”?
- Exposed Webcam Viewer — hotels in Russia, lobbies in California, and blinking lights in the darkness from all around the world. (via Hacker News)
- Beauty and Joy of Computing — an introductory computer science curriculum developed at the University of California, Berkeley, intended for non-CS majors at the high school junior through undergraduate freshman level. Uses Snap, a web-based implementation of Scratch.
Street View Tiles Hacks, Policy Simulation, Map Tile Toolbox, and Connected Sensor Device HowTo
- HyperLapse — this won the Internet for April. Everyone else can go home. Check out this unbelievable video and source is available.
- Housing Simulator — NZ’s largest city is consulting on its growth plan, and includes a simulator so you can decide where the growth to house the hundreds of thousands of predicted residents will come from. Reminds me of NPR’s Budget Hero. Notice that none of the levers control immigration or city taxes to make different cities attractive or unattractive. Growth is a given and you’re left trying to figure out which green fields to pave.
- Converting To and From Google Map Tile Coordinates in PostGIS (Pete Warden) — Google Maps’ system of power-of-two tiles has become a defacto standard, widely used by all sorts of web mapping software. I’ve found it handy to use as a caching scheme for our data, but the PostGIS calls to use it were getting pretty messy, so I wrapped them up in a few functions. Code on github.
- So You Want to Build A Connected Sensor Device? (Google Doc) — The purpose of this document is to provide an overview of infrastructure, options, and tradeoffs for the parts of the data ecosystem that deal with generating, storing, transmitting, and sharing data. In addition to providing an overview, the goal is to learn what the pain points are, so we can address them. This is a collaborative document drafted for the purpose of discussion and contribution at Sensored Meetup #10. (via Rachel Kalmar)
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.
Hi-Res Long-Distance, Robot Ants, Data Liberation, and Network Neutrality
- Millimetre-Accuracy 3D Imaging From 1km Away (The Register) — With further development, Heriot-Watt University Research Fellow Aongus McCarthy says, the system could end up both portable and with a range of up to 10 Km. See the paper for the full story.
- Robot Ants With Pheromones of Light (PLoS Comp Biol) — see also the video. (via IEEE Spectrum’s AI blog)
- tabula — open source tool for liberating data tables trapped inside PDF files. (via Source)
- There’s No Economic Imperative to Reconsider an Open Internet (SSRN) — The debate on the neutrality of Internet access isn’t new, and if its intensity varies over time, it has for a long while tainted the relationship between Internet Service Providers (ISPs) and Online Service Providers (OSPs). This paper explores the economic relationship between these two types of players, examines in laymen’s terms how the traffic can be routed efficiently and the associated cost of that routing. The paper then assesses various arguments in support of net discrimination to conclude that there is no threat to the internet economy such that reconsidering something as precious as an open internet would be necessary.

Island Traps, Apolitical Technology, 3D Printing Patent Suits, and Disk-Based Graph Tool
- Trap Island — island on most maps doesn’t exist.
- Why I Work on Non-Partisan Tech (MySociety) — excellent essay. Obama won using big technology, but imagine if that effort, money, and technique were used to make things that were useful to the country. Political technology is not gov2.0.
- 3D Printing Patent Suits (MSNBC) — notable not just for incumbents keeping out low-cost competitors with patents, but also (as BoingBoing observed) Many of the key patents in 3D printing start expiring in 2013, and will continue to lapse through ’14 and ’15. Expect a big bang of 3D printer innovation, and massive price-drops, in the years to come. (via BoingBoing)
- GraphChi — can run very large graph computations on just a single machine, by using a novel algorithm for processing the graph from disk (SSD or hard drive). Programs for GraphChi are written in the vertex-centric model, proposed by GraphLab and Google’s Pregel. GraphChi runs vertex-centric programs asynchronously (i.e changes written to edges are immediately visible to subsequent computation), and in parallel. GraphChi also supports streaming graph updates and removal of edges from the graph.
