This document provides an overview of OpenStack, an open source cloud computing platform. It begins with background on OpenStack's history and community. It then discusses the key OpenStack projects including Compute (Nova), Object Storage (Swift), Image Service (Glance), Identity (Keystone), Block Storage (Cinder), and Networking (Quantum). It explains the architecture and communication between the different OpenStack components. Finally, it covers the networking options in OpenStack including Flat, Flat DHCP, and VLAN modes.

P2P Container Image Distribution on IPFS With containerd and nerdctlKohei Tokunaga
Talked at FOSDEM 2022 about IPFS-based P2P image distribution with containerd and nerdctl (Feburary 6, 2022).
https://fosdem.org/2022/schedule/event/container_ipfs_image/
nerdctl is a Docker-compatible CLI of containerd, developed as a subproject of containerd. nerdctl recently added support of P2P image distribution on IPFS. This enables to share container images among hosts without hosting or relying on the registry.
In this session, Kohei, one of the maintainers of nerdctl, will introduce IPFS-based P2P image distribution with containerd and nerdctl. This session will also show the combination of IPFS-based distribution with the existing image distribution techniques, focusing on lazy pulling (eStargz) and image encryption (OCIcrypt). The status of integration work with other tools including Kubernetes will also be shared.

It's 2021 and containerization has been happening for 7 years already.
In the Java space, there are several ways to package a Java application as a Docker image.
Let's discover them from the Dockerfile to the CNCF Buildpacks, mentioning the Jib way too!

[KubeConEU] Building images efficiently and securely on Kubernetes with BuildKitAkihiro Suda
https://sched.co/MPX5
BuildKit is a modern container image builder that focuses on efficiency and security, mostly known as the backend of Docker 18.06+ and Jessie Frazelle's `img`. (But it is even useful as a standalone tool!)
In this talk, Akihiro Suda, one of founding maintainers of BuildKit, shows practical tips for running BuildKit on Kubernetes clusters.
KubeCon EU 2016: Secure, Cloud-Native Networking with Project CalicoKubeAcademy
Why does the network matter and why does it need to be simple (the 3am test)? Why should we build networks that scale to the extremes and how can we do that with proven technologies? Finally, how can we secure microservices, why should we bother, and what does this mean for developers and operators?

At Qt Day 2019 in Florence, Italy, I gave a presentation about "Using Qt under LGPLv3".
In the first part, I go through Section "4. Combined Works" and explain the obligations of LGPLv3 in detail.
When you combine your application with the Qt libraries, you can keep closed the source code of the application and publish the application and the Qt libraries under your license terms. You must satisfy the following conditions.
On a physical medium like a USB drive or DVD, you must provide the source code of the Qt libraries, the text of the LGPLv3 and GPLv3, the Copyright notices of the Qt libraries, a description of your modification of the Qt libraries and the installation information. If your application has a user interface, you must display the license texts of the LGPLv3 and GPLv3 and the Copyright notices in this user interface.
The installation information - a.k.a. the anti-tivoisation clause - describes how the user can build a modified version of Qt, how to install this version on the device, and how to run the application with the modified Qt version on the device. If you build a B2B product, you need not provide the installation information.
In the second part, I compare the costs of Qt Commercial and Qt LGPLv3. You must check the licenses for all packages of the (embedded) Linux system, no matter whether you use Qt Commercial or Qt LGPLv3. Qt commercial adds per-developer fees and per-unit fees (royalties). If you use Boot2Qt, Qt for Automation, Qt Safe Renderer or other commercial add-ons, Qt Commercial may well be worth the additional costs.
In the third part, I show how Yocto (bitbake) and Fossology help with the compliance checks. Fossology is a license and copyright scanner.
KubeCon EU 2016: What is OpenStack's role in a Kubernetes world?KubeAcademy
OpenStack is a global open collaboration to produce an open source infrastructure stack. Since its creation 5 years ago, it moved from an open source compute / object storage IaaS solution to about 30 projects providing programmable infrastructure building blocks. How does this project fit in a container-driven future ? How complementary is it with Kubernetes ? In this talk, Thierry Carrez will detail the long-term vision for OpenStack: infrastructure for a programmable infrastructure world and an integration engine for future infrastructure technologies.

[KubeCon EU 2021] Introduction and Deep Dive Into ContainerdAkihiro Suda
Join containerd maintainers and reviewers in a combined introduction and deep dive session. They will discuss the overview and the recent updates of containerd as well as how it is being used by Kubernetes, Docker and other container-based systems. The brief introduction about its architecture and service design will be included. The talk will also deep dive into how to leverage contained by extending and customizing it for your use case with low-level plugins like remote snapshotters, as well as by implementing your own containerd client. Upcoming features and recent discussion in containerd community will also be covered.

[FOSDEM 2020] Lazy distribution of container imagesAkihiro Suda
https://fosdem.org/2020/schedule/event/containers_lazy_image_distribution/
The biggest problem of the OCI Image Spec is that a container cannot be started until all the tarball layers are downloaded, even though more than 90% of the tarball contents are often unneeded for the actual workload.
This session will show state-of-the-art alternative image formats, which allow runtime implementations to start a container without waiting for all its image contents to be locally available.
Especially, this session will put focus on CRFS/stargz and its implementation status in containerd (https://github.com/containerd/containerd/issues/3731). The plan for BuildKit integration will be shown as well.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
