VertexDB is a high performance graph database server that supports automatic garbage collection. It uses the HTTP protocol for requests and JSON for it's response data format and the API is inspired by the FUSE filesystem API plus a few extra methods for queries and queues. It's implementation is currently built on top of TokyoCabinet and libevent.
Elevation is a free, open source route visualizer that renders personal GPS data in 3D space, built in Processing by Dave Shea.
This series of abstract data visualisation represents the source code structure and work progress of a software collection. The intention was to represent the sheer volume of work put into open source software development and usually by a smal number of people.

The following maps represent the first stage of a project I am embarking on to map out some of the spatial contours of Wikipedia. Data were obtained from the August 2009 Wikipedia geodata dump organised by user Kolossos. The information was then ported over to a GIS. There are almost half a million geotagged Wikipedia articles (i.e. Wikipedia articles about a place or an event that occurred in a distinct place), so the preparation time alone for the files needed to create these maps was almost a week.
Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110m scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software.

Their separate privacy policy for the Google Public DNS strikes me as utterly reasonable, particularly given its very rapid (24-48 hours) deletion of what I would consider to be the key privacy-sensitive data.

GeoAPI services include a reverse geocoder; deep data about 16 million businesses and tens of thousands of points of interest; a writable layer for developers to annotate the world and do complex geo-queries; and location-enabled media layers (e.g., Twitter and Flickr). We've also recently added an iPhone SDK to speed up mobile development.
Over the last couple years, we see an emerging data storage mechanism for storing large scale of data. These storage solution differs quite significantly with the RDBMS model and is also known as the NOSQL. The aim of this blog is to extract the underlying technologies that these solutions have in common, and get a deeper understanding on the implication to your application's design.
It's also possible to create some APIs that would tell a website how much bandwidth is available to it, so the developer could adjust its features accordingly. This idea is being tossed around between web companies and operators, but I don't know how much is actually being done about it.
In this age of information overload, a new solution is emerging that could help us cope with the oceans of data surrounding and swamping us. It's called information visualisation.
The SHERPA/RoMEO Application Programmers' Interface (API) is a machine-to-machine interface that lets programmers access SHERPA/RoMEO data from their applications. For instance, you could use the API to incorporate an automatic look-up of a journal or publisher into your repository's deposition process.
Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and "fiddle" with incoming or outgoing data. Fiddler includes a powerful event-based scripting subsystem, and can be extended using any .NET language. Fiddler is freeware and can debug traffic from virtually any application, including Internet Explorer, Mozilla Firefox, Opera, and thousands more.
This is a parser for HTTP messages written in C. It parses both requests and responses. The parser is designed to be used in performance HTTP applications. It does not make any allocations, it does not buffer data, and it can be interrupted at anytime. It only requires about 128 bytes of data per message stream (in a web server that is per connection).
9/11 tragedy pager intercepts.
The following are national US pager intercepts that cover the September 11 tragedy from 3am on the same day (Tuesday) until 3am the following day.
Due to popular demand we provide a new block of pager data every 5 minutes, synchronized to the actual time of day the message was sent.
This way the world has a chance to objectively see how the tragedy progressed.
A full archive containing all the messages will be released on Thursday November 26 at the conclusion.

For a little while I had been taking pictures of objects, furniture, buildings and other things in my environment where I recognised, however abstract, a face.
To do this, it needs to have access to the individual pixels of the images it's operating on -- which is why for jQSlickWrap to work, you need to have a browser that supports HTML 5's new canvas element. Here's an overview of the algorithm: 1. If necessary, pre-load the image. 2. Determine the CSS styles for the image (float and padding). 3. Create a canvas element and set its dimensions to the size of the image plus its padding. 4. Draw the image onto the canvas in the top-left location. 5. Figure out the "background" color of the image by examining the pixel data at the top-left corner of the image. 6. Fill the canvas with this background color.

Recently I’ve been doing some ‘gardening’. You can see this clearly from these images on NearMap…. What’s really special about NearMap apart from the fact they are updating imagery more often than I am at home is that they have integrated OSM into their viewer and you can use their data to update OSM:
Using a SQL database as storage for as handle server allows greater control over data deposits as well as permitting complex data query.
