VMware to open source: what do you need to consider? | Ubuntu
You might have read our previous blog VMware alternatives: discover open source where we discussed why you should consider open source-based infrastructure if you’re looking for VMware alternatives. We also held a webinar on the topic, where we received quite a lot of relevant audience questions that we wanted to elaborate on further. Read on for some of the most important considerations when thinking about migrating from VMware to Ubuntu-based open-source infrastructure.

Canonical has a wide range of infrastructure products that can be combined in different ways to deliver a full solution for your specific needs. It is difficult, and it would be misleading, for us to recommend one single option as a like-for-like alternative.
If you are after a full private cloud on a mid to large scale, our Openstack solution might be the right one for you. If you are looking for a virtualisation layer, you might be interested in LXD, or an LXD-based micro cloud for a small-scale deployment. If you are interested in running cloud-native workloads our Kubernetes offering is the one to go with. Our Charmed Ceph solution might be suitable for your storage needs. There is no one-size, or rather a one-solution-fits-all approach.

A custom PipeWire node - Bootlin's blog
As described in previous articles (Introduction to PipeWire, Hands-on installation of PipeWire), the PipeWire daemon is responsible for running the graph execution. Nodes inside this graph can be implemented by any process that has access to the PipeWire socket that is used for IPC. PipeWire provides a shared object library that abstracts the communication with the main daemon and the communication with the modules that are required by the client.
In this blog post, our goal will be to implement an audio source node that plays audio coming from a file, in a loop. This will be an excuse to see a lot of code, showing what the library API looks like and how it should be used. To introduce some dynamism to a rather static setup, we’ll rely on an input from a Wii Nunchuck, connected using a custom Linux driver and relying on the input event userspace API.

Give back to open source on Giving Tuesday | Opensource.com
Giving Tuesday is always a reminder to me to consider how to give back to open source projects, communities, and organizations. In 2012, GivingTuesday was created to encourage people to simply do good. "Since then, it has grown into a year-round global movement that inspires hundreds of millions of people to give, collaborate, and celebrate generosity."
When I think about all the ways I have benefited from "standing on the shoulder of giants," both professionally and personally. I start to think about all the individuals and organizations that have made being part of the open source community such a rewarding experience. Many have used an open source project or joined an open source community and immediately benefited from the contributions of past and current members.
When you dig a little deeper, you’ll find that many of the organizations listed below have volunteer opportunities, ways to get involved with their community, and simple things like sharing information about why you support the organization or joining a newsletter to stay updated. They offer a variety of ways to support them beyond just financial donations.
The list below is not an endorsement from myself or my employer, it is a collection of organizations for you to consider as you look at groups to support and ways to donate time, money, expertise, and other skills you might offer. I would encourage you to do your own research before making a donation, particularly if you are looking for any tax deductions.
