Researchers analyzed frequency time-series data from the Continental European power grid by splitting it into hourly chunks and averaging to reveal a recurring 'waveform' pattern within each minute. They found frequency is typically highest at the start of each minute and then declines for several seconds to half a minute, with the pattern's amplitude varying by time of day but its basic shape remaining stable across hours, days, and multiple grid systems.

A reviewer shares detailed impressions of Paul E. McKenney's open-access book 'Is Parallel Programming Hard, And, If So, What Can You Do About It?', tracing how attending the 2026 Software Should Work conference and conversations with Fil-C creator Filip Pizlo sparked renewed interest in concurrency after a period working with TLA+ and a failed attempt to learn Lean. The piece recounts the reviewer's background before diving into reactions to McKenney's material on synchronization and concurrent programming.

Telstra's mobile network suffered widespread disruption on 8 July 2026 after a single GPS receiver in a Melbourne chassis, restarting from maintenance, reverted to believing the year was 2006 and spread that false timestamp across the network. The failure knocked out voice calls, texts, and even emergency number access, while also disrupting trains, payment terminals, ticketing systems, and EV chargers. An independent review by Technology Audit Partners found no cyberattack, cut cable, or power failure was involved—just a corrupted time reference.

Scientists linked ultra-precise optical atomic clocks located in four different nations and successfully compared their timekeeping with extremely high accuracy. The experiment demonstrated that these clocks, which are far more precise than the cesium clocks defining current international time standards, can be reliably synced across long distances.
