A rare hybrid bird, resulting from the mating of a male blue jay and a female green jay, has been discovered in suburban San Antonio, Texas. Researchers from The University of Texas at Austin believe this hybrid is one of the first instances of vertebrate hybridization due to climate-related range shifts of both parent species. Traditionally separated by about 7 million years of evolution and with non-overlapping ranges only a few decades ago, both species have expanded their habitats in response to changing weather patterns.

The article discusses the challenges and solutions in representing decimal numbers in computing, as most everyday numbers are non-integers and computers originally focused on integers. Different numeric formats have been developed over time to handle these representations, with no single solution fitting all domains. The "double" is highlighted as the most common numerical type in modern computing, widely used in scientific libraries, graphics engines, and machine learning frameworks due to its speed and efficiency. Defined by the IEEE-754 standard, a double is a

A Guardian investigation has uncovered that Dollar General and Family Dollar frequently fail to honor their shelf prices, leading customers to be charged more at checkout for various items. During an inspection in Windsor, North Carolina, state inspector Ryan Coffield scanned 300 items, finding a 23% error rate with prices ringing up higher than displayed—far exceeding the state's acceptable limit. Items like frozen pizzas and paper towels were among those mispriced, and the store had failed inspections consecutively with fines imposed for previous violations.

The content discusses the differences between mutexes and spinlocks as synchronization primitives in programming. It highlights how engineers often fall into the "synchronization primitive trap" by choosing the inappropriate primitive for their scenario. Mutexes allow threads to sleep, which is beneficial for short critical sections but can be detrimental when latency is critical. Spinlocks, on the other hand, keep the CPU busy while waiting, which can waste resources, especially in scenarios with contention. A spinlock uses a continuous loop with atomic operations

The content discusses how systems maintain their integrity and shape through constraints, comparing this to the surface tension of water that resists external pressure. In software, integrity is crucial; it allows systems to manage side effects and maintain coherence when changed. The text highlights the importance of type systems, invariants, and defined boundaries that specify what is allowed within a system, preventing ambiguity that could lead to instability. It explains that some systems are well-structured with clear rules that prevent errors, while others can become chaotic

Sam Zeloof, a college senior who originally created integrated circuits in his garage, has developed a new chip called the Z2, which features a 100-transistor array built on a 10µm polysilicon gate process, similar to that used in Intel's first processor. His earlier Z1 chip had only 6 transistors and served as a test for his fabrication techniques. The Z2 chip, with its capabilities, is a significant advancement towards more sophisticated DIY computer chips, especially as

The discussion on tech forums about the decline of Perl reflects on its cultural roots, particularly its conservative and reactionary community values, which inhibited its evolution as a mature programming language ecosystem. The author, who wrote Perl in the mid-90s and worked on major web projects with mod_perl in the early 2000s, attributes Perl's stagnation to a "BOFH" culture derived from its UNIX sysadmin origins. This culture fosters a tribal, introverted community with social norms and elit
