Xoranth’s musings

Xoranth’s musings is a small personal blog collecting long-form technical write-ups by a developer who works close to the metal. Rather than news or tutorials, the site publishes occasional deep dives into how compilers and low-level code actually behave, with each post dated and available through the site’s RSS feed for readers who prefer to follow along.

The published pieces show the focus clearly: one examines how GCC lowers switch statements, another optimizes a perfect hash function built on the pext instruction, and a third looks inside memcmp as implemented on Intel AVX2 hardware. Each article walks through concrete implementation choices, instruction-level behavior, and performance reasoning instead of staying at a conceptual level.

The audience is systems programmers, compiler enthusiasts, and performance-minded C developers who are comfortable reading assembly and reasoning about CPU features. Readers looking for introductory material or regular publishing cadence will find the archive sparse, but those chasing precise explanations of specific mechanisms will find the posts worth the effort.

A practical approach is to subscribe to the RSS feed and treat the archive as reference material, returning to a post when a related problem appears in your own work. The value here is depth on a few narrow topics rather than breadth, making it a useful stop for engineers who enjoy understanding exactly what the machine does.
