MiniPerf

Example of how to capture CPU counters with ETW on Windows, perf on Linux or kperf on Apple.

Using ETW needs somewhat recently updated Windows 10 or 11. Not sure about exact version.

Currently tested on:

etw on Qualcomm Snapdragon X Elite, Windows 11, arm64
etw on AMD Zen 3, Windows 11 (with virtualization enabled in BIOS)

Fib

Simple fibonacci number calculator.

Usage: fib nth Fibonacci number

Is there an ultimate Makefile?: Part 1 - Applications

Have you ever struggled with writing your Makefile manually or dealing with your projects without depending on a specific IDE? If so, this article is for you to break your chains.

Picture this: a Makefile that adapts to your project like a chameleon, requiring only a few parameter tweaks to fit most of your needs. Gone are the days of wrestling with convoluted build scripts or spending hours integrating external libraries. With this Makefile in your arsenal, you'll conquer the build process with ease and finesse.

Who is this article for?

If you have a GNU Linux development environment.
If you are using GNU compilers such as g++.
If you don't depend on any IDE for project configurations.
