C-Macs is a unique Cocoa application that pushes the boundaries by being written entirely in C, with no Nibs or Objective-C code. It is remarkably efficient, using minimal memory and featuring a red square drawn in Core Graphics. The author provides no license, warning users to proceed at their own risk and avoid using Objective-C […]
Enhancing the switch construct allows handling exceptions from the selector, making switch more useful for pattern matching. Previous updates prevented automatic NullPointerExceptions for null selectors, improving readability. Introducing case throws enables developers to locally handle exceptions directly within the switch, eliminating the need for cumbersome try-catch blocks. Exception cases are separate from normal cases, with […]
In February 1938, Guy Stewart Callendar presented a bold idea to the Royal Meteorological Society: human activity was warming the planet due to CO2 emissions from burning fuel. Despite skepticism, Callendar persisted in his research, using data analysis and physics to support his claims. His groundbreaking work accurately predicted global temperature increases and climate change […]
Bjarne Stroustrup’s “Programming: Principles and Practice Using C++, Third Edition,” serves as a comprehensive introduction to programming for beginners and those looking to enhance their coding skills in modern C++. This revised edition focuses on foundational programming concepts rather than technical details, covering procedural, object-oriented, and generic programming. Stroustrup emphasizes writing efficient, maintainable, and type-safe […]
Memory safety issues are widespread in current architectures. The CHERI project offers a solution by enhancing security with minimal changes to C code, using hardware capabilities and Clang/LLVM and GCC. CHERI is undergoing testing by Arm and Microsoft for future use in mass-market systems. The challenge lies in defining CHERI C semantics clearly for porting […]

Ants exhibit a collective behavior known as an “ant mill” or “Death Spiral,” where a subset of ants get separated and start following each other in a continuously rotating circle, leading to exhaustion and death. This phenomenon reflects dysfunctional behavior that can also be seen in failing companies experiencing decline. Researchers suggest a similar process […]
