New Method To Detect and Prove GPL Violations

qwerty writes "A paper to be presented at the upcoming academic conference Automated Software Engineering describes a new method to detect code theft and could be used to detect GPL violations in particular. While the co-called birthmarking method is demonstrated for Java, it is general enough to work for other languages as well. The API Benchmark observes the interaction between an application and (dynamic) libraries that are part of the runtime system. This captures the observable behavior of the program and cannot be easily foiled using code obfuscation techniques, as shown in the paper (PDF). Once such a birthmark is captured, it can be searched for in other programs. By capturing the birthmarks from popular open-source frameworks, GPL-violating applications could be identified."

Computer Interaction in Science Fiction Movies

MidVicious writes "From futuristic 'Punch Cards' to Voice Recognition HoloDeck Interfaces, human/computer interactions have always mirrored the base concepts of our emerging technologies. An article from a Saarland University CS Seminar highlights Hollywood history with UI, ranging from the moderately feasible (Total Recall's television/scenery display wall) to the often ridiculous (Swordfish's 6-flat screen monitor setup complete with 3-D virus-hacking environment). An interesting read, especially considering some of the technology is on its way to becoming a reality."

Sixty Years of Memex

CubicStar writes "Sixty years ago, Vannnevar Bush published on 'Atlantic Monthly' his seminal article on the Memex, that computer-like device which would provide access to a huge amount of interlinked information. At the time computers were experimental and secret but a visionary (with a shadowy edge) proposed something which even today looks at least influential."

3D Raytracing Chip Shown at CeBIT

An anonymous reader submits "As noted at heise.de Saarland University is showing a prototype of a 3D Raytracing Card at CeBIT2005. The FPGA is clocked at 90 MHz and is 3-5 times faster in raytracing then a Pentium4 CPU with 30 times more MHz. Besides game engines using raytracing there was a scene of a Boeing with 350 million polygons rendered in realtime."

Quake III Gets Real Time Ray-Tracing Treatment

Ozh writes "Did you ever wonder what you could do with a cluster of 20 AMD XP 1800s? Some German students and videogame fans did, and their answer has been what they call 'ray-tracing egoshooters', an entirely raytraced game engine which 'runs about 20 fps@36 GHz in 512x512 with 4xFSAA'. The first game to get this treatment is Quake 3 Arena : the screenshots look slightly better than the original 3D engine but the video (56 Mb, 3'19) is quite dramatic."
