memsparkline – Track RAM usage of process and descendants in real time

In plain words

Memsparkline is a command-line tool that monitors RAM usage for a process and its child processes in real time. It displays memory consumption data visually, making it easy to identify which processes are using the most resources. The tool is designed for developers and system administrators who need to track memory behavior during program execution. It's available on GitHub.

  I started working on my ideas a few months ago. I've shipped 4 apps so far. I love my numbers, so every morning I'd go through the payments dashboard, analytics, bug reports, feature requests, and everything else for each app. I wished for a single place to view it all, so I built Motherboard. It runs locally in the browser and tracks any visible data point from any website with just a click. A single dashboard for everything. Life's good.

  Lovable▲1,477

  Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…

  I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!
