Evolutionary Database Design In the past decade, we've seen the rise of agile methodologies. Compared to their predecessors they change the demands on database design. One of the most central of these demands is the idea of evolutionary architecture. On an agile project you assume that you cannot fix the requirements of the system up-front. As a result having a detailed design phase at the beginning of a project becomes impractical.

Get Help The Pan-American Institute of Geography and History (PAIGH) is a technical and scientific body of the Organization of American States specializing in the areas of cartography, geography, history and geophysics. 21 Pictures That Will Restore Your Faith in Humanity: How BuzzFeed makes viral hits in four easy steps Photograph by Michelle Gantner/ Last Wednesday, BuzzFeed’s Jack Shepherd published an irresistible piece called, “21 Pictures That Will Restore Your Faith in Humanity.” The post is exactly as advertised, a rundown of photos of people being more wonderful than you’d expect—rescuing animals from danger, helping strangers in need, expressing tolerance for others, and all manner of additional good stuff. It became an instant hit on Reddit, Twitter, and especially Facebook, where it has earned more than 2 million Likes. So far, the post has attracted more than 7 million views, and as of Tuesday morning, its traffic shows no sign of abating. When I saw Shepherd’s piece, my first thought was, Why didn’t I think of that?

Knowledge tags Tagging was popularized by websites associated with Web 2.0 and is an important feature of many Web 2.0 services. It is now also part of some desktop software. A Description of the Equator and Some Otherlands, collaborative hypercinema portal, produced by documenta X, 1997.

R2V, raster to vector conversion, GIS, mapping, CAD R2V is an advanced raster to vector conversion software for automated map digitizing, GIS data capture and CAD conversion applications. R2V is currently being used in more than 60 countries by thousands of users for mapping and GIS data conversion applications. R2V supports fully automatic vectorization and interactive line tracing from scanned maps and drawings. R2V inputs bi-level, grayscale, and color images in TIFF, GeoTIFF, GIF, JPEG, RLC, PNG or BMP formats. It exports vector data to ArcView Shapefiles, Arc/Info Generate, MapInfo MIF/MID, AutoCAD DXF, IGES, STL, VRML, SVG ( Scalable Vector Graphics) and MapGuide SDL formats. R2V provides complete on-screen image and vector editing, labeling, and geo-referencing using GeoTIFF or user specified control points, image rubber sheeting, color image classification and separation, text symbol detection and recognition (OCR), automatic polygon layer creation, 3D DEM and Grid creation, and 3D display and image draping.

Knowledge Is a Common Good - Transform Network The Effects of the Open Source Movement on the Development of Politics and Society Introduction In October 2009, Transform! co-promoted the first Free Culture Forum (FCF). The FCF is one of the first attempts to create an international space of networking and strategic reflection for a wide range of movements that have emerged across the world in different fields and are related to the production, access, circulation and management of cultural works and knowledge goods. It concluded an intense three days’ work with the release of a Charter for Innovation, Creativity and Access to Knowledge, which condensed demands, principles and concrete actions to differently regulate the legal, political and economical challenges posed by the revolution taking place in the way that knowledge, information and culture are created, accessed and transformed.

This site publishes high-touch, time-intensive data visualizations (and has a business that sustains it) Over 7,000 artists played in the New York City area in 2013. Only 21 of those later made it, really made it, headlining at a venue with an over 3,000-person capacity — among them, bigger names like Chance the Rapper, X Ambassadors, Sam Smith, and Sylvan Esso. I learned this sort of random but fascinating tidbit from a data visualization titled “The Unlikely Odds of Making it Big,” from the site The Pudding. The Pudding is the home to high-touch, painstakingly crafted data visualizations — what the site calls “visual essays” — that are distinct in their obsessive complexity over points of cultural curiosity. Most pieces stand wholly apart from the U.S. news cycle; no anxiety-inducing interactives around budget, taxes, health care.

How to Burst the "Filter Bubble" that Protects Us from Opposing Views The term “filter bubble” entered the public domain back in 2011when the internet activist Eli Pariser coined it to refer to the way recommendation engines shield people from certain aspects of the real world. Pariser used the example of two people who googled the term “BP”. One received links to investment news about BP while the other received links to the Deepwater Horizon oil spill, presumably as a result of some recommendation algorithm. This is an insidious problem. Much social research shows that people prefer to receive information that they agree with instead of information that challenges their beliefs. This problem is compounded when social networks recommend content based on what users already like and on what people similar to them also like.

Canadian socioeconomic database from Statistics Canada Website Evaluation 2017 Français Thank you for visiting Statistics Canada’s website. You have been selected to participate in a brief evaluation to help us improve the website. Exploring the 'Net and Star Trek with Pearltrees Over the past few days, you may have noticed that we've embedded a new tool known as Pearltrees in certain articles on TG Daily. For example, we added a "pearltree" in a post about WikiLeaks and accident-prone Japanese nuclear facilities, and another in an article describing the enigmatic Anonymous and their nemesis Backtrace Security. As you can see, Pearltrees embeds a significant amount of supplemental information related to a post in a way that is easy to navigate, while giving you a chance to preview content before you even click a link.

MosquitoMap and the Mal-area calculator: new web tools to relate mosquito species distribution with vector borne disease MosquitoMap website The web server hosting the MosquitoMap home page provides access to historical accounts for particular datasets, information on how to contribute data, and metadata information for vector and pathogen models. The data portal within the MosquitoMap webpage leads to the application server containing the map viewer and mosquito collection database. Base maps featured in MosquitoMap include ESRI® World satellite imagery and World Streetmap provided by ArcGIS Online Resource Centers [12]. MosquitoMap has pan and zoom controls, and is designed to operate similarly to other mass-market Internet mapping sites like Google Earth™. Mosquito collection point data are stored in an ArcGIS Server 9.3 Enterprise SDE/SQL Server 2005/2008 Standard geodatabase that includes GADM administrative area (see below) and vector species x country lookup tables, derived from the literature.

British Medical Journal: Statistics Notes Announcement British Medical Journal: Statistics Notes Perhaps the finest series of short articles on the use of statistics is the occasional series of Statistics Notes started in 1994 by the British Medical Journal.
