An Informal Catalog of Slit-Scan Video Artworks and References
"Slitscan^w imaging techniques are used to create static images of time-based phenomena. In traditional film photography, slit scan images are created by exposing film as it slides past a slit-shaped aperture. In the digital realm, thin slices are extracted from a sequence of video frames, and concatenated into a new image." [via] [more inside]

According to the photographer's daughter, "All photos in this collection were taken by then Lt. and later Capt. George S. White, my Father, while he was serving in the Pacific as a pilot. They are generally between 1945 and 1948 from what is documented." My favorites? The barmaid or postwar Tokyo or wrecked planes and airplane graveyards.

Bytecode-based virtual machines are the Next Big Thing in programming. You can run Lisp, Ruby, Python, OCaml, and yes even COBOL on the JVM. Or if you prefer your languages to be a bit more melodic there's J#, A#, P# and F#. Even C/C++ has a bytecode compiler now. That's not to mention languages that have their own VMs like Erlang or that are writing their own like Parrot or PyPy. [more inside]

The stupa (aka the chorten or the pagoda) is Buddhism's universal piece of symbolic architecture. Borobodur in Java is probably the most famous, while Burma's Shwedagon Pagoda is the largest, and the Kyaik-htiyo Pagoda on the Golden Rock may be the most precarious. They're common across the Himalayas, and sometimes hidden in caves.

Not your ordinary mud volcano. This erruption might be manmade and it is quickly engulfing a large swath of Eastern Java. The putrid gas and mud have been flowing since May, and recent attempts to control the flow have led to demonstrations serious enough for the govenrment to issue "shoot-on-sight" orders. The flow could last for another hundred years.

In April of 1817, a distraught, exotic, bizarre young lady wearing a black turban appeared in the village of Almondsbury, England. She spoke an unintelligible language, and mystified villagers brought her to see the local magistrate. Linguistic experts of the day were baffled: until a Portuguese sailor appeared, who claimed to be able to translate. He explained that she was kidnapped royalty from the island of Javasu. She called herself Princess Caraboo.
