In plain words
Open-source tools designed to help developers diagnose and troubleshoot issues in Kubernetes applications. The suite provides utilities for collecting logs, analyzing cluster configuration, and identifying common problems. It's built for DevOps engineers and application developers working with Kubernetes environments who need systematic ways to investigate failures and performance issues. The tools automate much of the manual troubleshooting process typically required when debugging containerized applications.

Without installing anything to the cluster, Preflight analyzes the environment, comparing it to your requirements. A visual report is generated to highlight where the environment doesn't meet your requirements. Without installing anything in to the cluster, data is collected from your application based on what was defined in your collector. Sensitive information is redacted from a support bundle and is never stored, keeping your data safe and secure. Without installing anything to the cluster, your Support bundle is analyzed and insights are surfaced to help you debug and resolvefrom troubleshoot.sh

Talanoa▲340Hi 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…

Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time. Instead, I rejigged/relaunched it via a Reddit forum this February as free and open - and have now gathered a team of helpers to ensure that it keeps going each month even after I can’t…
