Quarterly Food-at-Home Price Database The Quarterly Food-at-Home Price Database (QFAHPD) provides food price data to support research on the economic determinants of food consumption, diet quality, and health outcomes. There are two versions of the database--please read the complete documentation before downloading the data. Version 1 of the Quarterly Food-at-Home Price Database (QFAHPD-1) contains prices for 52 food groups based on both UPC-coded and random-weight food purchases. Quarterly prices are available for:
GCHQ presents CyberChef, an Open Source Data Analysis ToolSecurity Affairs Open data are a privileged source for intelligence agencies, almost any government is largely investing in technology to analyze them. Recently the British intelligence Agency, the Government Communications Headquarters (GCHQ), has launched a new open source web tool specifically designed for analyzing and decoding data. The tool dubbed CyberChef has been presented by the GCHQ as the “Cyber Swiss Army Knife.” “CyberChef is a simple, intuitive web app for carrying out all manner of “cyber” operations within a web browser. These operations include creating hexdumps, simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, data compression and decompression, calculating hashes and checksums, IPv6 and X.509 parsing, and much more.” reads the description published by the GCHQ on GitHub.
Blog Announcement Community ~ gsoc It’s a great news, Gephi has been accepted again for the Google Summer of Code for the 5th year! The program is the best way for students around the world to start contributing to an open-source project. Since 2009, each edition is a great success and dramatically boosted Gephi’s project development. What is Gephi? Networks are everywhere: email systems, financial transaction systems and gene-protein interaction networks are just a few examples.
Catalog The Socrata Open Data API (SODA) allows software developers to access data hosted in Socrata data sites programmatically. Developers can create applications that use the SODA APIs to visualize and “mash-up” Socrata datasets in new and exciting ways. Create an iPhone application that visualizes government spending in your area, a web application that allows citizens to look up potential government benefits they'd overlooked, or a service that automatically emails you when new earmarks are added to bills that you wish to track. To start accessing this dataset programmatically, use the API endpoint provided below. For more information and examples on how to use the Socrata Open Data API, reference our Developer Documentation. Wikipedia:How to read an article history - Wikipedia This page on how to read an article history is intended as an aid to people who are researching with Wikipedia. Experienced Wikipedians often glean a great deal about articles from looking at the page history and following up to the individual edits that make up that history. This page describes some of these tricks of the trade. The suggestions here apply mostly to substantive articles with a number of contributors. If the page history indicates that the page is entirely or almost entirely the work of one person, you are dealing with a situation more comparable to evaluating an article on someone's private web site.

Why no one uses your government data » Ben Balter Publishing government information is about much more than simply throwing 0’s and 1’s over the firewall. It’s about building ecosystems and communities. It’s about solving shared challenges. It’s about consumption — after all, that’s the American way. Go to any agency website, and chances are you’ll find at least one dataset sitting idly by because the barrier to consume it is too damn high.
QueryVOWL QueryVOWL is a visual query language for Linked Data based upon the ontology visualization VOWL. It has been designed as an intuitive and easy to use language with clear mappings to SPARQL. In contrast to related work, the queries can be created entirely with visual elements, taking into account RDFS and OWL concepts often used to structure Linked Data. Related projects are VOWL and SparqlFilterFlow. The language reference describes the visual elements and their mappings to SPARQL. The web demo provides a prototypical implementation of QueryVOWL.
Mapping redheads: which country has the most? A couple of months ago this map did the rounds. It's quite nice right? It shows that in most of Scotland and Ireland, as well as a random patch in central Russia, 10% of people are of the ginger genre. By contrast, less than 1 in every 100 people in southern Europe have red hair. Protovis Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction.

Federal Government Challenges Post-Safety Datapalooza At last month’s White House Safety Datapalooza, several federal agencies issued challenges to civic minded developers to help the federal government solve real world problems ranging from health care, public safety, education, and more. Many of the previous winners of these challenges have been civic startups who have leveraged open data released on data.gov to help find creative ways to solve problems. Sketchnotes at the Public Data Safetypalooa, courtesy @anadiazhernandz Here’s a list of each challenge along with data resources and some examples of apps that work to solve similar problems.
