1. AI Flame Graphs 2025-01-20

   tags: artificial-intelligence, intel, performance/profiling, programming/c++, programming/python, visualization

   AI developers think about their bit of code, but with AI Flame Graphs they can now see the entire stack for the first time, including the HW, and many layers they don't usually think about or don't know about. It basically looks like a pile of gibberish with their code only a small part of the flame graph.

   This reaction is similar to people's first experiences with CPU flame graphs, which show parts of the system that developers and engineers typically don't work on, such as runtime internals, system libraries, and kernel internals.

   The benefits are there: you get wonderful type system, wonderful performance, and build times that give you back those coffee breaks you used to get while your code compiled.
