SVG is magical when you think about it. It's one of the few formats both developers and designers can interact with. With the rise of SVG compatibility on the web, the format has enjoyed various new use cases with the HTML5 specification. Could it be used as a common file format both designers and developers can collaborate together? As SVG is basically just lines of code, shouldn't designers b...

The topic of additional repositories comes up on a regular basis. The official position is to submit everything to Factory to avoid the issue, but for a large number of reasons this cannot always be the case. As such users living in the real world have to navigate the unsupported landscape. By far the best approach is to use repository priorities available through libzypp, but unfortunately thi...

The Heroes were founded two years ago. In this time, we worked hard to maintain and enhance the openSUSE infrastructure, but talking about that would be boring.

Of course, if you do a lot of things, you'll sometimes also make mistakes.

Have a lot of fun with some of our failures, what we learned from them and where we still have room for improvement.

A quick introduction to the concept of a Serverless and Function-as-a-Service followed by a live demo session based on the SUSE Container-as-a-Service-Plarform (CaaSP v2.0). The presenter will cover the following topics:

• What is Serverless and OpenFaaS
• Use Helm to setup OpenFaaS in SUSE CaaSP and/or test it using DockerSwarm
• Create your own openFaaS openSUSE Docker image in DockerHub...

In Tumbleweed with have roughly ~25.000 packages for 64-bit architecture. Do you know how many of those are actually install-able? From those who are not, do you know the reason behind? Do you know how many of those will become install-able if boo#123456 gets fixed? And from those which can actually be installed, do you know if there are any glitches at the post-installation scripts?

-Sure, ...

Open Build Service frontend was started in 2005, even before the first version of Rails was released.It is most likely one of the oldest Rails Project that people still keep using! That implies that legacy code and refactoring are two daily topics in all OBS developers’ lives.

As said, OBS has already some years and because of that all kind of talks about it have been held: how to use it, it...

In a way, both Docker and Tor are shrouded in mystery. Containers have been the biggest thing in the IT field in the past few years and yet a lot of people don't know what they are good for. Why not just use a VM? Likewise, Tor is known only for the negative uses and connotations such as "The Dark Web" and "The Deep Web" meanwhile not many people know about the actual positives of the technolog...

Driven by curiosity and some late night ebay purchases, I ended up down the rabbit hole of building a cloud from scratch: why use OpenStack when you can do it the hard way. This was a great excuse to dive into the various subsystems required to assemble a cloud and to find out how frustrating aspects of it could be.

A cloud is a jigsaw, requiring many different pieces to fit together and co-...

The original Ceph Manager Dashboard that was introduced in Ceph "Luminous" started out as a simple, read-only view into various run-time information and performance data of a Ceph cluster, without authentication or any administrative functionality.

However, as it turns out, there is a growing demand for adding more web-based management capabilities, to make it easier for administrators that ...

Event logging is a central source of information for IT operations and security. The syslog-ng application collects logs from many different sources, performs real-time log analysis by processing and filtering them, and finally it stores the logs or forwards them for further analysis. The same feature set comes in handy in a containerized environment too, where you start and stop containers aro...

Identihub is the first Open Source visual assets management software which can also be self-hosted. Identihub can host icons, logos, photos, fonts and colors on a single page, making it easy to share them with other people, eliminating the need to send .zip fles back and forth with a specific resolution. This makes the collaboration between designers and non-designers easier, as they don't need...

Kdump is a vital tool for debugging severe kernel crashes, especially if the failure can't be reproduced easily or an direct access to the system is not possible.

When an sever error happens in the kernel, a new crash kernel get loaded which saves the memory of the crashed system. These dump can be used to analyze the state of the machine and hopefully give insights on what has happened.

The current EU Copyright Reform proposal puts pressure on platforms to monitor and filter all content, including uploaded free and open-source software, for copyright infringement (Article 13), proposes a new 20-year license for news snippets (Article 11), and limits who can access datasets -- including open data (Article 3). Any of these would be terrible outcomes. Let's demand better copyrigh...

Tumbleweed, being a rolling distribution, is constantly changing and packages are constantly being rebuilt against one another and updating requirements. As such it becomes necessary to update even when undesirable. For example, one is running snapshot 17 and the next day snapshot 18 contains a QT update that rebuilt a large number of packages. When attempting to install an application that dep...

Ever since the openSUSE conference in 2016, openSUSE has its own professional, yet software driven set of hardware. However, we are not yet self-hosted on openSUSE, owed to various issues ranging from missing packages to legal issues. We also rely on YouTube rather than promoting free, self-hosted video portals.

In this workshop, we will lay out the current situation, assess the required wo...

Containers are becoming more and more popular way how we develop and deploy applications. We trust them to protect our applications, but do we understand how they security model works? How they're isolated and sand-boxed? Let's look at all the pieces in Linux which are there to isolate and support containers security. We will then continue with overview what every deployment pipeline should per...

With openSUSE Leap, we've tried a new management model based on SLE. The same is true for the kernel, one of the most "core" packages in the whole distribution. However, in the case of kernels, a story is a bit different from others.

Šifrování se stává stále běžnějším a dostupnějším, většina navštěvovaných webů dnes má HTTPS. Neodmyslitelnou součástí dobře navrženého šifrování je také autentizace. V případě TLS se o ni starají certifikáty. Co to přesně certifikát je, jaká je jeho role a co všechno v něm najdeme?
