Rust: Filling the Native Development Gap

2025-07-17

The author, seeking a suitable language for writing a native desktop application, after careful consideration, finally chose to try Rust. He eliminated C++ (too complex), C (too low-level), and Go (convenient, but compromises on memory management). TypeScript, while convenient, lacked the "solid" feel of a native program. Ultimately, Rust, with its higher level of abstraction and fine-grained control over memory management, emerged as the best choice to fill the native development gap, despite the author's prior lack of experience with the language.

The Legend of Mel: A Real Programmer's Hexadecimal Blackjack

2025-07-16

This article recounts the story of Mel, a legendary programmer from the 1980s. A master of machine code, Mel wrote a blackjack game for the LGP-30 computer at Royal McBee, later optimizing it for the RPC-4000. He eschewed compilers and optimizing assemblers, manually optimizing code to exploit the drum memory architecture for maximum speed. Even simple loops were ingeniously crafted, using instruction address overflow to terminate, avoiding explicit tests. While forced to add a win/loss switch, he subtly reversed the logic, making the program always win when activated, showcasing his unique style and ethical stance. The article highlights Mel's profound skill and dedication to his craft.

The Secret to Faster, More Accurate Code: Mental Code Proofs

2025-07-16

This article unveils a technique for writing code faster and more accurately: performing "online" proofs. Instead of interrupting your coding flow, mentally prove your code's correctness as you write. The author details several strategies to aid in this process, including focusing on code monotonicity, utilizing pre- and post-conditions, maintaining invariants, and isolating the impact of changes. Inductive reasoning for recursive functions and data structures is also highlighted, along with advocating for "proof-affinity" as a code quality metric. Finally, the author suggests practicing mathematical proofs to sharpen your code-proving skills.

High-Performance Dynamic Dispatch with GLIBC hwcaps

2025-07-16

This article demonstrates how to leverage GLIBC 2.33+ hwcaps for simple dynamic dispatch in amd64 and POWER shared libraries. By creating library files for different CPU instruction sets (e.g., x86-64-v4, x86-64-v3, etc.) under `/usr/lib/glibc-hwcaps/`, the dynamic linker automatically loads the corresponding library based on the highest instruction set supported by the CPU, optimizing performance. This solves the challenge of maintaining consistent library performance across different CPU architectures, as demonstrated in the Debian packaging of the ggml library used by llama.cpp and whisper.cpp.
