I really wish we'd stop calling them climate "skeptics" or "vaccine skeptics", if you jump off a cliff we don't call you a "gravity skeptic"

New! After eight years of waiting, they're online! See London's unbuilt motorways as even their planners never could in our amazing, immersive Ringways Map, hosted by the amazing SABRE Maps. It *might* be the best thing we've ever done. #ringways
The Ringways Map is here
The wait is over! The full map of the Ringways, London’s unbuilt urban motorway network, is now online. Not even the system's planners had anything like this.

Lotus's decision in the 1980s to convert its DOS products to OS2 rather than Windows, little remembered today, was one of the truly catastrophic mistakes in modern IT history. Lotus opened the door wide for Excel and Word, and relegated itself to the dustbin of history.

Earth science departments are being gutted across the country, which is utterly bizarre given their relevance to our understanding of climate, hazards and disasters, the soils that feed us, the industries that drive our economies, and the importance of ancient life to understanding biodiversity.
I have just heard an ALARMING report that my former Department of Earth and Atmospheric Sciences at the University of Nebraska is threatened with elimination, due to a university & state-wide budget crisis, and despite their ongoing success in scholarship and teaching. This is really shocking.
