Show HN: Single-Header Profiler for C++17
(github.com/DmitriBogdanov)
utl::profiler is single-include solution for localized profiling, it features simple macros to measure how much time is taken by a certain scope / expression / code segment. Profiler automatically builds a call graph for all profiled functions and prints a nicely formatted table for every thread. See examples.

Always Use Max Models in Cursor IDE
(vincentschmalbach.com)
If you've been using Cursor IDE since its early days, you might have noticed a bizarre decline in quality around the time Claude 3.7 Sonnet was released. What used to be a reliable AI coding assistant suddenly became frustratingly obtuse - missing obvious references, forgetting about files you explicitly added to context, and generally acting like it had severe memory issues.

I Use Cline for AI Engineering
(addyo.substack.com)
The AI coding assistant landscape is saturated with tools that promise to revolutionize development workflows. As an engineer who has worked with complex systems for decades, I approach such claims with healthy skepticism. After extensively testing the major players (Cursor, WindSurf, GitHub Copilot, and others), I've found Cline - a free VSCode plugin - to be uniquely valuable for serious engineering work. Here's why, along with important caveats and trade-offs to consider.

Revisiting Uv
