Daniel Chase Hooper explores type safe generic data structures in C by exploring a real-world example of a generic queue data structure, implemented in C. He explains the problems with traditional C's lack of generics and how existing libraries like GNU C Library's gmpq and gmpn only support a limited set of types. Hooper then presents his own implementation of a generic queue using C type punning and function pointers, providing a detailed walkthrough of the code. He highlights the benefits of this approach, including improved code safety and maintainability. The article concludes by discussing the potential applications and limitations of this implementation.

A former SR-71 engineer, Bob Bishop, has been working on a revival program for NASA's Blackbird, a top-secret stealth aircraft. Bishop, who worked on the original SR-71 program in the 1960s and 1970s, has been leading a small team to design and build a new Blackbird aircraft. The new Blackbird is expected to be a supersonic aircraft capable of flying at speeds of up to Mach 3.5, or around 2,200 miles per hour. The aircraft will be powered by a pair of Pratt & Whitney J58 engines, the same engines used in the original SR-71. Bishop's team has already built a 1/20 scale model of the aircraft and has conducted wind tunnel tests to validate its design. The team is now working to build a full-scale prototype, which is expected to be completed in the next few years. The revival program is being funded by a private investor and is not affiliated with NASA, although the agency has been briefed on the project.
