You only need the frontier model for one single edit
/prewalk hands the cheap model a trajectory, not a plan, retaining 92–97% of frontier pass rate at roughly half the cost on SWE-Bench Pro.

Quadrupling code performance with a "useless" if
So I was optimizing a domain-specific compressor the other day, as one does. One important problem was chunking the input string and optimally choosing the most compact encoding for each chunk (different encodings compress different characters better, so where to split is not immediately obvious). The previous post…

Your code is fast if you're lucky
Recently, while working on an optimized Quicksort implementation, I came across a rather interesting quirk. Modern compilers (especially Clang) optimize loops using fast, branch-free instructions - provided you use the right programming style.

Good Tools Are Invisible
TL;DR: A good tool is and ought to be invisible—striving to make such tools is the goal of a toolmaker.One habit I see a lot, and have to push back on, is taking a tool's shortcomings and reselling them as a "puzzle game" which is "fun" to solve.I don't want my tools to be "fun". I want my tools to be invisible.Text…
