Map is a built-in type that acts as a key-value storage. Unlike arrays where you’re stuck with keys as increasing indices like 0, 1, 2, and so on, with maps, the key can be any comparable type.

Identify and fix common JavaScript memory leaks (Node.js and Deno.js)

I share the story of a frustrating debugging journey with a Rust application that was migrated to Kubernetes. Everything seemed fine until a suspected memory leak caused our application to scale uncontrollably. I dove deep into tracing memory usage with eBPF, heaptrack, and jemalloc profiling tools. The real twist came when I discovered that the memory leak was a phantom menace - a misinterpretation of Kubernetes memory metrics rather than a genuine issue. This post details the steps I took, the tools I used, and the lessons I learned about problem-solving, metric accuracy, and effective debugging in containerized environments.

Shows how much the performance of Go has improved from version 1.0 through to 1.22 (including PGO) -- in its compiler, runtime, and libraries.

In the One Billion Row Challenge, the task is to write a program capable of reading an 1-billion-line file (with around 13GB), process and aggregate temperature readings from various weather stations, and present a report of the results on console. In this article, I share my experience attempting the challenge with Golang, providing the details of how I achieved 1.96 seconds.
