Zsh ist meine Default shell. Nicht mehr neu und fancy (siehe e.g. nushell) aber immer noch so viel besser als bash. Kurzvortrag (der noch vorbereitet werde muss) Grml-zsh Demo. Kein OmyZsh.

I would like to explain my proposal for using Hashtags within the Fediverse (Mastodon) as an (additional) blog comment solution: https://karl-voit.at/2026/08/22/Blog-Comments-via-Hashtags/  Either you want to maximize user interaction with yet another channel or you want to have an alternative solution for static blog pages, this idea might be a very easy to implement idea to enable Millions of pe...

It is well known that humans are the weakest link in information security. Social engineering has emerged as a means to influence and manipulate individuals to achieve desired outcomes. In this presentation, we delve into the realm of social engineering, exploring the art of behavior alteration, manipulation and persuasive communication.

In this session I want to give a short introduction to the open-source off-grid-communication project Meshtastic. I'm by no means an expert but I got interested in it a few months ago and want to answer the following questions in my talk: - What is the technology behind Meshtastic? - What can you do with it? - What do you need to participate? - How do I connect my typewriter to Meshtastic? I will...

Slides: https://öä.eu/vibe.pdf / .odp I'll try to answer the following questions: * How can you use LLMs in CTFs and in security analysis for your software? * How big is the phenomena already? Are CTFs "broken" now? * How good is AI in IT security? Should I be scared? Can I ignore the trend? * What model and agent frameworks are good? Will contain * a little recap on what CTFs are * what's the rec...

* Disclaimer: This talk is actually offered by TTH, but since account creation is disabled, jstsmthrgk generously shared his credentials. .  In den letzten 2 Jahren habe ich mich etwas umfangreicher mit öffentlichen Kameras in Österreich beschäftigt. Gegen meinen Willen wurde ich dabei von mehr und mehr Geräten mit den Plaintext Passwörtern ihrer Benutzer beworfen. Und da dachte ich mir, wir könne...

When Project TEMPA first analyzed Tesla’s BLE passive entry system in 2022, we found several glaring security flaws. In 2024, Tesla responded by quietly rolling out a significantly improved version of the PhoneKey protocol to millions of vehicles. While the security posture has undoubtedly improved, it’s not completely bulletproof yet. This talk breaks down the recent changes to the protocol, expl...

Choosing the right tool for a job is hard. People often need to migrate to yet another tool after a few months or years because their original tool choice didn't turn out so good after all. This talk gives some insight into some common issues when dealing with Personal Information Management, Information Storage, Management and Retrieval. With this understanding, many things related to tool choice...

Das Arch User Repository (AUR) ist aktuell immer wieder in den Linux Schlagzeilen, weil vermehrt Malware durch dieses verbreitet wird. Von Linux-VeteranInnen wird hier oft nur empfohlen man müsse eben die PKGBUILDs (Installationsskripte) durchlesen. Diese Empfehlung geht jedoch an der Nutzungsrealität der meisten LinuxianerInnen vorbei. Dieser Vortrag gibt eine Einführung in das AUR, beschreibt wi...

Panoramax started a few years ago in France, initiated by OpenStreetMap France and IGN. This project is part of the OSM family, because ground level pictures are so useful for OSM mappers. This talk will provide an overview of the project, how it works, the full open-source approach, the decentralization and federation, and will describe the next steps, including the launch of the Panoramax Founda...

We welcome the OpenStreetMap community in Paris and online to celebrate the international State of the Map conference. This session will also provide some formal instructions and helpful information. You will for example learn how the Q&A (question and answer) sessions are run and what we will do at the social event.

Mit dem Informationsfreiheitsgesetz gibt es seit 1. September 2025 ein neues Bürgerrecht in Österreich. Aus ersten Behörden- und Gerichtsentscheidungen ziehen wir Zwischenbilanz: was gut funktioniert, wo es noch Baustellen gibt, und was gar nicht geht. Gehalten vom Forum Informationsfreiheit (FOI), Österreichs führender NGO für die Informationsrechte von Bürgerinnen und Bürgern. Orga-Link: https:/...

Der Vortag soll einen Einblick in die aktuelle Technologie, aus der Perspektive eines österreichischen Herstellers von 3D Laserscannern, geben. Was steckt da alles drinnen, wo wird diese Technik überall eingesetzt und welche Herausforderungen für die Zukunft gibt es.

👀 Nicci wird lustige Anekdoten aus dem Leben als Queere und Taube Person erzählen. Da hat Nicci viel erlebt im bisherigen Datingleben und Missverständnissen, also… lachen wir zusammen! ℹ️ Sprache: Es findet in Österreichischer Gebärdensprache statt und wird in deutsche Lautsprache übersetzt. Der Auftritt wird vom Verein Gebärdenverse (Deaf Hackingverein aus Wien) organisiert. Licensed to the publ...

Embedded Linux is now used in more devices than ever before. I would like to provide an overview of the advantages and disadvantages of embedded Linux, as well as the available hardware and tools. Additionally, I will share some insights from my experience of working in this field for over five years.

The Fediverse is a great place to be as a "social network": https://karl-voit.at/2024/06/18/Fediverse-and-Mastodon/ In case you've heard about it but can't really grasp it yet or if you do have starting issues, you might want to ask a few questions. If you would like to get practical tips to fill your timeline, increase your consuming efficiency, "netiquette" on how you should post your own stuff...

Bei diesem Talk geht es um die Themenvielfalt die auch in Kärnten  rund um das Thema Computer herrscht. Von Hackerspace bis Linuxtag - wir haben viel zu bieten.

Im September 2025 genügte eine einzige Phishing-Mail an einen npm-Maintainer, um binnen rund 16 Minuten Schadcode in 18 zentrale Pakete mit über 2 Milliarden Downloads pro Woche einzuschleusen. Wem können wir noch trauen, wenn wir gemeinsam an Open Source Software arbeiten? Der Cyber Resilience Act gibt darauf eine regulatorische Antwort, mit ersten Pflichten schon ab September 2026. Der Vortrag e...

Sydbox is a sandbox, designed to contain and isolate processes from each other - similar to Bubblewrap, Firejail, GVisor, and minijail. By being very paranoid and leveraging as many of the tools that the linux kernel gives us it manages to do some surprising things. This talk wants to show some of the design decisions, some of the more unconventional features, and a live demonstration how this can...

In this presentation I'll discuss the ongoing port of KDE Linux to use BuildStream. Rather than describing the work done and to be done, we'll discuss the why, the difficulties this brings and what kind of opportunities does it unveil. Furthermore, we'll discuss the implications to the end user of using an overly immutable root file system and what kind of restrictions does this impose on the desi...

Open source projects get forked. They get acquired. They lose contributors, fracture communities, and sometimes quietly stop being open in a meaningful sense. This talk uses ownCloud's history as an honest case study in what goes wrong and what it actually takes to fix it. We'll cover the real lessons from operating a major project without proper open governance, what prompted a course correction,...

In this talk, I want to give an overview of the changes that Google has introduced in the past twelve months in the Android ecosystem and how they are affecting Android users, device manufacturers, custom ROM maintainers and the open-source community in general. Furthermore, I want to explore the possibilities of how the community can and is already adapting to the changing landscape. Last year, G...
