Motivation As seen from the title, I’m a huge Dune fan. Much like sandworms lurking beneath the surface, ready to appear unexpectedly, the scale and complexity of observability data can be just as massive, unpredictable, and a little terrifying. “But I do see a way. There is a narrow way through.” – Paul Muad’Dib Atreides, Dune Part Two Sci-fi analogies aside, designing high-throughput…
Python’s Performance Revolution Since Python 3.11, there has been a strong, ongoing effort to make Python faster, and the results are clear. Performance improvements are real, and the work continues. It’s both refreshing and surprising to see such significant speed gains in a language that’s nearly 30 years old. But make no mistake: there’s no magic here. In my humble opinion,…

Go is one of its kind when it comes to profiling. It includes powerful and opinionated(!) profilers inside the runtime. Other languages like Ruby, Python, or Node.js, contains profilers or a few APIs for writing profilers. But they are limited in scope compared to what Go offers out of the box. If you want to learn more about the types of observability tools that Go provides, I highly recommend…

My shell is slooow! This is my first blog post for years. I have been finding excuses for not writing one over the years, but I feel this is the right time. I was coding as usual when I started something odd with my shell. I have done few adjustments to my .zshrc file and out of a sudden it became very slow to spawn a new shell. As a person who has a obsession with performance, it became my duty…
