The Ba Congress was a meeting of representatives of the Chetnik movement led by Draža Mihailović (pictured) between 25 and 28 January 1944 in the village of Ba in German-occupied Serbia during World War II. The congress advanced a political alternative to the communist -led Anti-Fascist Council for the National Liberation of Yugoslavia (AVNOJ) of the Yugoslav Partisans . In December 1943, the major Allied powers had decided to provide their exclusive support to the Partisans and withdraw support from the Chetniks, as they had concluded that the Chetniks were more interested in collaborating with the Axis powers against the Partisans than fighting the Axis . The congress denounced the decisions of the AVNOJ, re-asserted its full support for the Yugoslav government-in-exile and opposition to the Axis, and proposed a Serb -centric vision for the political and socio-economic future of Yugoslavia. However, with the Allied policy change, nothing could be done to improve the position of the movement. ( Full article... )

Lidar is a method for determining ranges by targeting an object with a laser and measuring the time taken by the reflected light to return to the receiver. Lidar can also be used to make digital 3-D representations of areas on the Earth's surface and ocean floor, due to differences in laser return times, and by varying laser wavelengths. It has terrestrial, airborne, and mobile applications. This image shows an orthographic projection of a registered point cloud depicting the intersection of Folsom Street and Dore Street in San Francisco , California. The point cloud was captured over 18 seconds and registered in real time using an Ouster OS1 lidar unit mounted on a moving car. The points are coloured by a function based on raw lidar intensity multiplied by range, with orange signifying brighter regions and dark blue for darker regions. Lidar is a popular sensor for self-driving cars .
