"Honey Bunnies" is a generative art experiment showcasing a colony of stylized rabbits evolving and interacting within a simulated environment. These rabbits, rendered with simple geometric shapes, exhibit emergent behavior as they seek out and consume food, represented by growing and shrinking circles. The simulation unfolds in real-time, demonstrating how individual behaviors, driven by simple rules, can lead to complex and dynamic patterns at the population level. The visuals are minimalist and abstract, using a limited color palette and basic shapes to create a hypnotic and evolving scene.
This blog post presents a revised and more robust method for invoking raw OpenBSD system calls directly from C code, bypassing the standard C library. It improves upon a previous example by handling variable-length argument lists and demonstrating how to package those arguments correctly for system calls. The core improvement involves using assembly code to dynamically construct the system call arguments on the stack and then execute the syscall instruction. This allows for a more general and flexible approach compared to hardcoding argument handling for each specific system call. The provided code example demonstrates this technique with the getpid() system call.
Several Hacker News commenters discuss the impracticality of the raw syscall demo, questioning its real-world usefulness and emphasizing that libraries like libc exist for a reason. Some appreciated the technical depth and the exploration of low-level system interaction, viewing it as an interesting educational exercise. One commenter suggested the demo could be useful for specialized scenarios like writing a dynamic linker or a microkernel. There was also a brief discussion about the performance implications and the idea that bypassing libc wouldn't necessarily result in significant speed improvements, and might even be slower in some cases. Some users also debated the portability of the code and suggested alternative methods for achieving similar results.
