Finding random comparisons interesting and being disappointed with the limited and deterministic nature of Wolfram Alpha’s quantity comparisons, I created Nugacious to make random comparisons between physical quantities. Using a set of about 700,000 physical quantities extracted from DBpedia, an ontology created from Wikipedia infoboxes, an essentially limitless number of random comparisons are provided with links to their source Wikipedia pages for your reading pleasure. Try it today!
Two years in the making, I finally released Pannellum 2.0, which is a near complete rewrite. The renderer was replaced with raw WebGL, and multiresolution panorama support was added, along with a fallback CSS 3D renderer. Other additions include support for JSON configuration files, hotspots, tours, compass headings, CORS, partial panoramas, and cubic panoramas. I also put together a website for the viewer, registering pannellum.org. Unfortunately, there is still a dearth of documentation—something I need to work on. The below example demonstrates the multiresolution, hotspot, compass heading, and tour functionality using panoramas of the George Peabody Library and a JSON configuration file.
The Park River once flowed past the the Connecticut State Capitol’s gilded dome and was the centerpiece of its namesake, Bushnell Park, in downtown Hartford, but it is now mostly forgotten. After the floods of 1936 and 1938, it was decided that the river should be buried to prevent future flood damage. Under the direction of the United States Army Corps of Engineers, construction started in late 1940 to entomb the river in dual 20 foot by 30 foot concrete conduits from the Connecticut River to the Capitol, and finished in 1944. While this conduit worked well, it was decided that more of the river needed to be buried after the flood of 1955, and the Greater Hartford Flood Commission was established soon thereafter. During the construction of Interstate 84 during the 1960s, the State Highway Department built additional sections of conduit under the direction of the Flood Commission. The final sections of conduit, as well as an auxiliary tunnel to the Connecticut River, were built by the United States Army Corps of Engineers under the Park River Local Protection Project, which was authorized in 1968, with construction finishing in 1981. In total, almost four miles of river are buried, plus an additional two mile long auxiliary tunnel.
As I wrote last month, I recently got a set of NavSpark NS-RAW receivers. These can be used as a RTK GPS receiver system, but some sort of data link is needed. For shorter distances, XBee modules work well. Since I needed a convenient method for connecting the two devices together, both for the base station and the rover, I created an adapter board.
