It is not about just rebuilding using a different configuration, the application is still working running without JIT on non-SSE2 cpus, it is about generating x87 math instructions which is a bit trickier than using the SSE2 floating point assembler instructions.

Granted, this is on an old dual-cpu Athlon MP system so the absolute results are not comparable to anyone else but the relative results are

This is because the JavaScript engine (Carakan) does not currently compile to native code for CPUs lacking SSE2. Support for older CPUs will be added in future builds.

Laser Ignition May Replace the Spark Plug 388

dusty writes "Laser Focus World has a story on researchers from Ford, GSI, and The University of Liverpool and their success in using near-infrared lasers instead of spark plugs in automobile engines. The laser pulses are delivered to the combustion chamber one of two ways. One, the laser energy is transmitted through free space and into an optical plug. Two, the other more challenging method uses fiber optics. Attempts so far to put the second method into play have met some challenges. The researchers are confident that the fiber-optic laser cables' technical challenges (such as a 20% parasitic loss, and vibration issues) will soon be overcome. Both delivery schemes drastically reduce harmful emissions and increase performance over the use of spark plugs. So the spark plug could soon join the fax machine in the pantheon of antiquated technologies that will never completely disappear. The news release from The University of Liverpool has pictures of the freakin' internal combustion lasers."
