Red Hat OpenShift 4.7 Is Now Available
Based on Kubernetes 1.20 (and CRI-O 1.20), OpenShift 4.7 has made progress on a few new features and functionality across our supported infrastructures, core platform, and workloads, while making stability a major theme for this release. We made a number of changes across the stack to improve the stability and quality of the product.
They are fast! I remember times when OpenShift was versions behind Kubernetes releases. Now they are really up to speed again. I found nothing very special in this release, just a very solid maintenance release. Maybe: Argo CD is getting fully integrated which is cool!

Exactly 2 months after NeoChat 1.0, the NeoChat team is happy to announce a new release of NeoChat. NeoChat is a native client for the decentralized communication network Matrix.
The only missing piece in NeoChat: Encryption. Then it is already "perfect".

WhatsApp and most alternatives share the same problem – Jürg Stuker
#messenger, #matrix, #opinion
Shall I migrate to Signal, Threema or Telegram? No, because they all have — WhatsApp included — the same problem: They are walled gardens. Imagine a world where for each mail recipient using a separate domain, I would need separate mail client? Or in other words: Gmail users can only communicate with Gmail users.
Why I close PRs (OSS project maintainer notes) | Jeff Geerling
#opinion, #opensource, #contribution
I maintain many open source projects on GitHub and elsewhere (over 160 as of this writing). I have merged and/or closed thousands of Pull Requests (PRs) and patches in the past few years, and would like to summarize here many of the reasons I don't merge many PRs.
If you do not want a domain to receive any mail, there is a way to be at last somewhat civil about it. There's a different DNS trick for that.
A guide to setting up Kubernetes Service Level Objectives (SLOs) with Prometheus and Linkerd | Cloud Native Computing Foundation
#cncf, #slo, #metrics, #sre, #prometheus
In this tutorial, you’ll learn how to easily create service health SLOs on Kubernetes with Prometheus, an open source time-series database, and Linkerd, an open source ultralight service mesh.

Crossplane vs Cloud Provider Infrastructure Addons
Kubernetes has demonstrated the power of a well architected control plane with a great API. The industry is beginning to notice that this control plane can be used to do much more than orchestrate containers, and are increasingly looking to use the Kubernetes control plane to manage all of their infrastructure.
How NASA Designed a Helicopter That Could Fly Autonomously on Mars - IEEE Spectrum
#nasa, #mars, #helicopter, #linux
This the first time we’ll be flying Linux on Mars. We’re actually running on a Linux operating system. The software framework that we’re using is one that we developed at JPL for cubesats and instruments, and we open-sourced it a few years ago.
We recently completed most of the work and investments needed to issue 200 million certificates in a day and we thought we’d let people know what was involved.
