Cybersecurity Flaws Could Derail High-profile Cycling Races

High-end bicycles used for high-profile road races such as the Tour de France are vulnerable to cybersecurity attacks targeting the bike’s wireless gear shifting system.
The researchers are now working with Shimano, one of the leading bicycle component manufacturers, to patch the vulnerabilities.

Rounding Errors Could Make Certain Stopwatches Pick Wrong Race Winners

Obtaining split-second measurements relies on faultlessly rounding a raw time recorded by a stopwatch or electronic timing system to a submitted time. Researchers at the University of Surrey found certain stopwatches commit rounding errors when converting raw times to final submitted times. In American Journal of Physics, they outline a series of computer simulations based on procedures for converting raw race times for display.
