The Evolving Saga of 80387 FPU State Saving: A Tale of Documented Errors

2025-02-07

While investigating the behavior of x87 Floating Point Units (FPUs) and their state saving mechanisms (FSTENV/FLDENV and FSAVE/FRSTOR instructions), the author discovered discrepancies between early Intel documentation and later revisions concerning the 32-bit protected mode FPU state. Early 80387 documentation omitted the floating-point opcode from the 32-bit protected mode FPU state, while updated documentation included it. This led to several third-party reference books perpetuating the outdated information for years. The story highlights the evolution of technical documentation and how errors can persist in technical literature for extended periods.

Programming Languages: Balancing Safety and Power

2024-12-15

This article explores the trade-off between safety and power in programming languages. The traditional view is that powerful languages, like C with its manual memory management, are inherently unsafe. However, the author argues this is outdated. Modern language research shows that greater expressiveness allows for both safety and power. The evolution of macros in Lisp, Scheme, and Racket exemplifies this, demonstrating how improved design can enhance macro capabilities while maintaining safety. Racket's macro system is presented as a best practice, combining hygienic code with powerful manipulation capabilities. The article concludes that safe and reliable systems build more capable and reliable software, and recommends resources for further learning about Racket macros.

Decoupling Time Allocation from Capacity Allocation: The Key to Improved Team Efficiency

This article explores the misconceptions surrounding team capacity allocation. Many companies equate time allocation with capacity allocation, overlooking systemic factors affecting team capabilities. The author points out that capacity is not merely the sum of hours worked but encompasses team skills, tools, processes, and more. Focusing solely on time allocation while neglecting system optimization leads to inefficiency. The author recommends distinguishing between 'time allocation' (where the team spends its hours) and 'capacity allocation' (the team's true ability to deliver outcomes), considering various disruptive factors, for improved team efficiency.

Dark Matter's Surprising Origin: Fast Particles Slowing Down

Dartmouth researchers propose a novel theory for dark matter's origin. Their model suggests that in the early universe, high-energy massless particles collided and rapidly condensed, akin to steam turning into water, forming dark matter. These particles, attracted by opposing spins, cooled, and their energy plummeted, transforming into cold, heavy particles. The theory is testable via analysis of the cosmic microwave background radiation and draws an analogy to Cooper pair formation in superconductivity.

Automating C to Rust Porting with LLMs: A Surprisingly Effective Strategy

2025-06-18

This post details the author's experience automating the porting of C code to Rust using large language models (LLMs). After experimenting with several approaches, a strategy based on topological ordering and fuzz testing proved highly effective. Symbols in the C code were topologically sorted, then the LLM generated Rust versions of each symbol along with fuzz tests. Output comparison verified correctness. This successfully ported the Zopfli compression library from C to Rust with identical results. While not fully automated, this dramatically reduced cost and effort, offering a new approach to large codebase maintenance and upgrades.
