Since last year’s talk i’ve been working on modernising conky’s default

config system. There are a number of reasons for doing this from being

able to provide a default configuration that better adapts to the system

hardware to making it much easier to provide a modern look and feel.

In this talk i’ll talk about the parts of this process that were easy

because thanks to open source someone had already written something, the

frustrating parts because someone had created something really nice but

not licensed it. I’ll also talk about all the unexpected detours that I

took which included some lua packaging, learning to write lua bindings

and learning how to do proper font rendering on linux.

I’ll also share the current progress and how you can give it a shot

yourself along with what still needs to be done .

In this talk, you are going to learn about the recent changes that we have done to improve the user experience for openSUSE especially in Brazil, but also for South America.

There are many challenges when addressing issues in a country as big as Brazil or an entire continent, and we need your help to improve it further.

This talk should be a collection of first experience with the life of a packager (in this case, one of the team maintaining Python packages in SLE and openSUSE) on MicroOS, with read/only root and using various containerized tools like podman, distrobox and flatpak.

This talk will be about the creation of the openSUSE mirror in Open Labs Hackerspace.

By having a local mirror, we are trying to reduce the time it takes to download updates and software packages and by making it publicly available, we hope to bring more enthusiasts in our openSUSE community, in Tirana.

The mirror is being build and will be maintained by volunteers who are avid supporters of openSUSE distributions and are committed to helping others benefit from it.

A technical breakdown of the openSUSE mirror on how we have designed the infrastructure to be secure, available and easily maintainable will be provided.

Lastly, if you're curious about the openSUSE community in Albania, you'll definitely want to stick around!

A quick glance at mirrors.opensuse.org gives an idea on the disparity between the African continent and the rest of the world in terms of infrastructure to support open source. It's not just openSUSE but every other Linux distribution has just one or two, or no mirror at all in Africa.

The MicroOS Desktop started as a hairbrained, poorly thought out, "lets see what happens" concept at an openSUSE Conference not so long ago.

It's since become perhaps the most stable, reliable, and exciting Desktop offering the openSUSE Project offers.

This brief talk will provide a brief overview of the MicroOS Desktop project, advice for newcomers to the platform, and an open invitation as to how to contribute to help make openSUSE's latest and greatest Desktop OS even better.

Africa's internet speed is below the global average and that gives us a stronger reason why we need more mirrors in the continent.

In this presentation I'll explore how we built two additional openSUSE mirrors in Africa during the past year and what can be done to improve this picture, and reach out to more users in the continent.

For those who use Linux professionally in companies, proxy servers are a horror. Under Linux there is no central configuration of proxy servers and each major library / programming language implements its own implementation. If login data and so-called PAC proxies are added, which serve not only one but several proxy servers, it gets really complicated. This is where the library libproxy comes in and tries to solve this problem. By providing a simple and stable API it answers the question: Which way do I have to take to reach XYZ?

In this talk we will present libproxy, its current state and future development. Together we can solve the problem and bring this solution into the enterprises, so that Linux becomes even more integrated and established in the professional environment and their complex processes.

In recent years the amount of vulnerabilities and also the amount of systems, installations or containers a single sysadmin has to oversee has

grown beyond any human capable measures.

The best help here is more automation in various places, which needs to

be driven by automation consumable data.

We will look at two primary areas, the automation data provided by SUSE

for security fixes and also very fresh the inventory data, or "Software

Bill of Materials (SBOM)".

The talk will go over various formats, what SUSE offers and their

purposes and also give some future look out on more improved or even

more automation data formats.

This presentation gives an overview of application design and development for Kubernetes, the de facto standard for container orchestration in enterprises of all sizes.

Using a small web server code base as an example, the talk outlines the complete application lifecycle from the initial design to deployment, service-based access in addition to more advanced aspects such as scalability, resilience and high availability. The focus of this presentation is not so much on theory but rather practice using a live environment to demonstrate concepts and illustrate principles.

Overview of the talk:

- Application code base: The guinea pig

- Packaging: Image building and registry management

- Deployment: Populating the cluster

- Services: Internal and external network access

- High availability & resilience: Planning for the worst and beyond

- Advanced concepts: Load balancers, Ingress and more

- Spin your own: Kubernetes on a budget

- Discussion & Q&A

The presentation assumes a basic understanding of Docker and Kubernetes in addition to fundamental aspects of application design and programming.

OpenSUSE MicroOS, SLE Micro and the SUSE Adaptable Linux Platform (ALP) have moved to using SELinux for Mandatory Access Control (MAC).

There are some key differences between a traditional Linux system without MAC, and one with SELinux.

Furthermore, using SELinux on transactional systems such as openSUSE MicroOS and ALP-based distributions has its own peculiarities.

In this talk we will introduce SELinux, describe what it does, and show how to work with it.

We will then see how it's used on a transactional immutable system such as an ALP-based distribution, where most workloads are run inside containers.

This talk is for a beginner to intermediate-level audience.

You should have a general understanding of both traditional and immutable Linux systems, but won't need specific SELinux expertise.
