Polar Signals Continuous Profiler – Systematic Performance Profiling

Check out our new project to add some insight into OOM kill events for Go programs. Source code: https://github.com/parca-dev/oomprof/ Description of how it was put together: https://www.polarsignals.com/blog/posts/2025/08/13/oomprof

Polar Signals Continuous Profiler – Systematic Performance Profiling launched on February 9, 2021 with 44 votes, #1,086 of 3,133 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 5 years on.

In plain words

Polar Signals Continuous Profiler is a performance profiling tool launched in 2021. It helps developers systematically analyze and monitor application performance by collecting detailed profiling data. The tool is designed for software teams who need to identify performance bottlenecks and optimize their code. It operates as a continuous system, enabling ongoing performance monitoring rather than one-time snapshots, making it suitable for development and production environments.

    Hey HN. We’re Jay and Vadim from Highlight.io (https://highlight.io). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
