A recent discovery in the Android Carrier Config manager revealed a flag (KEY_INFLATE_SIGNAL_STRENGTH_BOOL) that allows mobile network operators to report signal strength as one bar higher than it actually is. This undocumented feature is accessible to operators like AT&T and Verizon, who have both enabled it on their networks. The motivation behind this flag remains unclear, but it raises concerns over transparency in network coverage claims alongside other misleading indicators, such as fake 5G flags. The author expresses skepticism about

The article discusses the historical significance of moving walkways, which are now common in airports and other public spaces but once amazed spectators. Highlighted is the 1900 Paris Exposition, where the moving sidewalk was first demonstrated and attracted the attention of Thomas Edison. Edison sent producer James Henry White to film the event, capturing 16 movies that showcased the novelty of the technology and the reactions of the crowd. The piece also includes hand-colored photographs from the exposition and describes the moving sidewalk as an innovative transit

The author discusses the question of why Isabelle, a proof assistant, omits proof objects, noting that this is related to their perceived unnecessary complexity in type theories. They reference the foundational insights of Robin Milner and the LCF architecture that enables type checking in implementation rather than logic, ensuring the validity of proof steps. The author reminisces about their experience with dependent types and their encounter with N.G. de Bruijn during a lecture on AUTOMATH. They mention challenges in accessing and using AUTOMATH due
