Release v1.19.1+k3s1 · rancher/k3s
#k3s, #kubernetes, #release

This release is K3s's first in the v1.19 line. It upgrades to Kubernetes version v1.19.1 and introduces several enhancements and many bug fixes.

My server is already upgraded and as always it was very smooth and easy: Replace k3s binary and restart all the things. With this release it's now possible to configure the system Helm charts using a custom resource named HelmChartConfig which I took as an opportunity to fix my configuration for to always work without manual intervention after a k3s upgrade: Commit a9d387acc0 says it all.


Interesting articles and blog posts

Reinventing virtualization with the AWS Nitro System - All Things Distributed
#aws, #virtualization, #story

Running a business at the scale of Amazon, we often have to solve problems that no other company has faced before. The disadvantage of this is that there is no “how to” guide for us—a lot is unknown. However, the advantage is that when we solve a new problem, it’s an opportunity to reinvent our services and create new benefits for our customers. Indeed, we have created some of our most innovative and successful ideas when we have entered unchartered territory.

The XY Problem

The Official, Authorized List Of Legitimate Reasons For Deciding to Become a Manager –
#management, #opinion

“Why did you decide to become a manager?” It’s a question that gets asked a lot, in job interviews, 1x1s, and plain old casual conversation.

How I Got An Offer At Facebook, Turned It Down, And Moved On
#job, #hiring, #story

Software Engineering (SWE) is among the most desired jobs nowadays.

I personally am absolutely not interested to work for one of these big companies. While it might be very interesting from a technical perspective (and maybe also from a financial point of view), I do not want to support monopoly companies becoming more and more the only ones dictating the Internet. I'm very much in favor of decentralization and this also belongs to the job I'm doing and the products I use daily.
