Der erste Prototyp funktioniert, jetzt ist der Weg über das Crowdfunding zum fertigen Produkt nicht mehr weit, oder? Nicht umsonst gilt das geflügelte Wort “Hardware is hard”. Wir haben in diesem Jahr mit Paperino eine erfolgreiche Crowdfunding Kampagne durchgeführt und ausgeliefert. In diesem Talk wollen wir vom Weg des Prototypen zum gelieferten Produkt erzählen. about this event: https://c3voc....

In diesem Vortrag stelle ich meine virtuelle Laborumgebung zum Testen von Monitoringsoftware vor. Mit libvirt und Ansible habe ich eine freie, portable Testumgebung aufgesetzt um das Monitoring-Werkzeug Sensu besser kennenzulernen. about this event: https://c3voc.de

In diesem Vortrag wird erläutert was über die Lebensgewohnheiten von Bewohnern einer Wohnung ausgesagt werden kann, wenn man die kontinuierlichen Aufzeichnung von Temperatur und Luftfeuchtigkeit in einem Wohnraum näher betrachtet. Außerdem wird ein Einblick gegeben wie man seine eigenen Smart Home Sensoren bauen kann und was dabei aus Datenschutzsicht zu beachten ist. about this event: https://c3v...

Biodaten erfassen wir “laufend”, zum Beispiel mit einem Pulstracker. Doch welche Relation gewinnen wir mit dieser Art Datenerhebung zu uns selbst? Das Konzept des Biofeedbacks schließt unmittelbar an eine soziale Realität an, die hier kurz auf den Begriff des quantified self gebracht sei. Doch ohne Kontext und bedeutungsvolles Spielen, erzählt jede Datenerfassung eine unvollständige Geschichte. ab...

DAU ... ist nicht nur ein bekanntes Akronym in der Soft- und Hardwareentwicklung ... nein es steht auch für den Datenunterricht ... einen Ansatz in der Informatikpädagogik. Seit viel zu langer Zeit wird in den Lehrplänen für Informatik das immer Gleiche gelehrt ... (MS-)Officeanwendung, Programmierung (Delphi und Assembler), Hardwareaufbau etc. und mit ein bisschen Glück und einer guten Informatik...

See how Red Hat's Session Recording project is using Systemd Journal to store and playback recordings of terminal sessions. Wonder at the challenges the project faces, such as dealing with various terminal types, character encodings, random playback positioning, etc. about this event: https://c3voc.de

Habitat is the best way for software developers to build, deploy, and manage modern applications - regardless of their expertise. Habitat provides a self-healing, self-configuring, stack-agnostic, frictionless abstraction for running applications—regardless of their complexity on whatever infrastructure you prefer, from physical hardware and virtual machines to containers and everything in between...

The introduction on Accelerated Networking on Azure created challenges integrating support in Linux distributions. The original method using bonding had issues that were solved by introducing a new mode called "Transparent VF". This mode solves issues with udev, cloudinit and distribution specific network initialization. This talk will also cover the process of how Linux support for Azure is integ...

Cockpit is an open source project that has built the new system admin UI for Linux. It turns Linux server into something discoverable and usable. Its goal is to remove the steep learning curve for Linux deployments. Cockpit lets you immediately dive into things like storage, network configuration, system log diagnosis, container troubleshooting and Kubernetes orchestration. All while being zero-fo...

Landlock is a proposal for a new Linux Security Module (LSM) to create secure sandboxes with the goal “to empower any process, including unprivileged ones, to securely restrict themselves.” This presentation will give an overview on what Landlock is, discuss the current status of the patchset and demonstrate how Landlock works, as well as its differences compared to other Linux security modules. a...

With the growing number of network cloud services it becomes essential to be able to monitor, troubleshoot and analyze different virtualization or container technologies. Being able to monitor complex heterogeneous federated cloud environments is key. Skydive is a real-time and post-mortem topology and packet analyzer. To do so, it listens for networking kernel events, monitors network namespaces,...

BPF is a Linux in-kernel virtual machine that is used for networking, tracing, seccomp and more. This talk will give an introduction to the extended BPF subsystem in Linux, an overview on how it works, show available tools to work with and explain possibilities as well as limits. about this event: https://c3voc.de

Open services mark a paradigm shift similar to the disruption caused by open-source software in the 90s, but the path to effective adoption of open services tooling is sometimes unclear. Blake will share patterns and learnings from his experience integrating one such tool, Habitat, at smartB GmbH. about this event: https://c3voc.de

As Infrastructure operators we're exposed to a lot of plumbing and not a lot of porcelain. Worse, because our concerns are often esoteric (in the eyes of application developers) we have to fix our own pipes too. Often this leads to the "homeowners dilemma"... Making the call of when to patch things up, when to rip out the pipes, and when to abandon gas lamps for electricity. We outline a number of...

systemd service management today supports a number of the features that container management is known for, but for classic system services. Let's see which ones, and how to make use of them. about this event: https://c3voc.de
