Ep. 42 - RevPar Problems, Real Talk: When Memes Meet Metrics with Calvin Tilokee How do revenue managers really think? What makes hotel rates spike during Taylor Swift concerts—or Bigfoot conventions? And why do memes about ADR hit harder than your star report? In this episode of Tickets to Travel: The Business of Travel Experiences , we sit down with Calvin Tilokee of RevPAR Media, the sharp mind behind the viral @RevPARProblems Instagram account. Calvin pulls back the curtain on hotel pricing strategy, compression events, influencer marketing, and what event producers often get wrong when pitching to hotels. Whether you’re trying to block rooms for a major festival, fill your hotel over a soft week, or just want to understand the secret language of revenue managers, this episode is packed with insight and humor. This episode is a must-listen for hotel sales and revenue teams, meeting and event planners, festival promoters, and hospitality marketers. Follow @RevPARProblems on Instagram for daily hotel truths and satire. And subscribe now to hear why Calvin says: “We don’t need your group when we’re already full. Call us the week after Christmas.” For more insider conversations at the intersection of travel, ticketing, and live experiences, follow us on all socials @Tix2TravelPod and subscribe wherever you get your podcasts.

Cracking Passwords for Fun and Profit (hackover2025) 1:01:44

vor 3 Tagen1:01:44

1:01:44

Wieso kommen meine Passwörter Abhanden? Wieso sind Sie nicht mehr sicher, wenn sie "Verloren" wurden? Was passiert mit Ihnen, wenn Sie in die falschen Hände geraten? Wie geht man vor, wenn man Passwörter erhalten hat? Wie kann ich mich schützen? Was kann ich tun um meine Passwörter zu verbessern? Wieso sollen die auch immer so lang sein? Was hat es mit dieser Katze da auf sich? Wie wird denn Geld mit meinen Passwörtern verdient? Diese und weitere Fragen, werden in dem Vortrag "Cracking Passwords for Fun and Profit" geklärt. Zusätzlich wird eine Demonstration gegeben, wie es aussieht und abläuft, wenn man mal eine Passwortliste "ausversehen" in die Hände bekommt.

The year 2024 in context of global climate change (hackover2025) 50:34

vor 3 Tagen50:34

50:34

Auf dem Hackover 24 hatten wir uns das Jahr 2023 im Kontext des globalen Klimawandels angeschaut. Der Vortrag endete mir der Aussicht, dass wir im Jahr 2024 das häufig medial beschriebene 1,5 Grad Ziel zu überschreiten dürften. Das haben wir auch erfolgreich geschafft. Der Talk stellt eine aktualisierte Version des Talks vom letztem Jahr dar. Wir fassen nochmal ein paar Punkte des globalen Klimaberichts des IPCC zusammen und ordnen dann die Messewerte des Jahres 2024 ein. Einige Teile sind daher für wiederkehrende Besuchende vielleicht vom letzten Jahr noch bekannt. Als neue Dimension (weil es Stand Juni 2025 in den Medien auftaucht) gucken wir zusätzlich auf das Grundwasser, da der Sommer für uns ja gerade erst beginnt.

Handheld Reverse Engineering am Beispiel des Game Boy Advance (hackover2025) 46:52

vor 3 Tagen46:52

46:52

In diesem Vortrag schauen wir uns an, wie der Game Boy Advance Handheld grundlegend funktioniert und wie mit gezielten Softwaretests neue Erkenntnisse gewonnen und die Kompatibilität von Emulatoren verbessert werden kann. Nintendo veröffentlichte den Game Boy Advance im Jahr 2001. Seitdem verkaufte sich der Handheld über 80 Millionen Mal und ist damit eine der meistverkauften Konsolen. Kurioserweise kam der erste Emulator für das System bereits vor dem offiziellen Release heraus und konnte bereits erste Demos ausführen. Seitdem hat sich das Verständnis der Hardware signifikant verbessert und damit auch die Detailgetreue von Emulatoren. In diesem Vortrag schauen wir uns an, wie die Hardware grundlegend aufgebaut ist und wie mithilfe gezielter Softwaretests neue Erkenntnisse gewonnen werden können. Dabei lege ich einen besonderen Fokus auf die 2D GPU / Pixel Processing Unit.

Microservices sind modern, eine Pipeline mit Message Queues und Cache wird da schnell mal hingeklatscht. In diesem Vortrag seht ihr ein anonymisiertes Fallbeispiel aus einem Projekt, bei dem der Cache inkonsistent wurde, fremde Devs mit Redis-Locks dagegen hielten bis das System lahmte und dann schnell die Firma verließen. Ich zeige euch, wie ich die Message Queues neu sortierte und anschließend alle Locks abschaffte, so dass doch noch ein stabiler Microservice herauskam.

Not Giving A Fuck (fusion25) 1:01:08

1:01:08

Gelangt die sexpositive Ära an ihr Ende? Ein Gespräch über das erotische Potenzial des derzeit vorherrschenden kollektiven Turn-Offs. Ein Gespenst geht um im Feminismus – das Gespenst der Unlust, des Überdrusses, der Enttäuschung über unerfüllte Glücksversprechen. Sexpositivität erzeugt Druck, die Arbeit an fuckability scheint wichtiger als der Genuss von Intimität. Beate Absalon lädt uns ein, neugierig zu sein. Auf welchen Sex haben wir keinen Bock mehr – und wie sähe ein anderer, utopischerer Sex aus? Sluts and Prudes vereinigt euch! Referenziertes Video bei 6:30 https://www.youtube.com/watch?v=ploHR84-9UA A specter is haunting feminism – the specter of disinterest, weariness, disappointment over unfulfilled promises of happiness. Sexpositivity creates pressure, and improving your fuckability seems more important than enjoying intimacy. Beate Absalon invites us to be curious: What kind of sex are we no longer interested in – and what would a different, more utopian kind of sex look like? Sluts and prudes, come together as one!

Der Westen hat keine Ahnung, was im Osten passiert (fusion25) 51:34

vor 10 Tagen51:34

51:34

Wer die allumfassende Normalisierung der extremen Rechten noch immer „nur“ auf Ostdeutschland projiziert, verharmlost die gesamtdeutsche und globale Krise. Aktivist und Autor Jakob Springfeld, geboren vor 23 Jahren im sächsischen Zwickau, liest bei uns aus seinem zweiten Buch (nach “Unter Nazis”) und erklärt, warum das Verantwortungspingpong zwischen Ost- und Westdeutschland enden muss. Für uns sind er und seine mutige Arbeit ein großes Vorbild und wir sind gespannt auf die anschließende Diskussion. Language: DE Translation: YES Recording: YES Anyone who still thinks of the extreme right as “just” an East German problem, is downplaying the crisis raging across Germany and around the world. Activist and writer Jakob Springfeld, who was born in Zwickau, Saxony, explains why the blame game between East and West Germany has to stop. We look forward to getting his perspective and even more to the subsequent discussion.

Production-Ready Virtualisation with Harvester and Longhorn (osc25) 16:57

vor 10 Tagen16:57

16:57

After _certain_ events caused massive upheaval in the virtualisation landscape, many companies using that technology have found themselves dropped into the deep end, with skyrocketing infrastructure costs and furious upper management. Promising a stark opposite to high costs, limited flexibility, and vendor lock-in, Harvester takes the stage. Harvester is an open source hyperconverged infrastructure solution built by SUSE, and provides a complete package for everything compute, networking, and storage. This presentation will take a peek under the hood of Harvester and how it leverages existing open source solutions to provide a scalable and resilient virtualisation platform - in particular Longhorn, which is the distributed block storage engine powering storage in Harvester and Kubernetes clusters around the world. Attendees will leave this talk motivated to replace their existing production infrastructure with Harvester, powered by the flexibility and high availability of Longhorn. So, whether you are looking at bringing the cloud back to your server room, or reducing costs with existing infrastructure (while ensuring prod isn't at risk), then this talk will get you started!

`mkosi-initrd` is a tool for building initrds using distribution packages that is gaining interest among systemd distributions, and can currently be used on openSUSE Tumbleweed. We will analyze in detail how it works, its weaknesses and its benefits, in order to ultimately try to provoke a change of mindset in developers accustomed to thinking only about `dracut` when implementing functionalities that have to run in the initrd.

The Future of Unattended and Advanced Linux Deployments (osc25) 40:42

vor 10 Tagen40:42

40:42

In this session, I will show you how to use Agama, the new next-generation installer, to perform effortless advanced unattended installations on openSUSE Linux. Whether you are installing just a few desktops or a fleet of servers, Agama makes the process fast, smooth, and hassle-free. This modern installer is poised to transform not only openSUSE installations but also deployments across other Linux distributions. While older tools like AutoYAST work well, they are not always easy or user-friendly for unattended advanced Linux installations. Agama solves this with a simple yet modern web interface that makes unattended installations easy and possible for everyone. I will demonstrate how to use Agama’s latest features, including how to set up and initiate remote connections using IP addressing or Multicast DNS for a fully unattended OpenSUSE installation. You will also learn about Agama’s main key features such as its simple JSON-based configuration language to create auto installation profiles, an HTTP API for integrating with third-party application tools, and how to import your existing AutoYAST profiles. Join this session to see how Agama can save you a lot of time and effort by making your OpenSUSE Linux deployments easier and more powerful than ever before.

openSUSE uses RPM for its own packaging needs, with macros on their own on top. However, the distributions using RPMs are just a couple compared to the vast Linux ecosystem. How are other distributions handling packaging? Are they using bash scripts, functions, or even declarative languages? This talk will give a rundown of the different approaches that have been more successful in building a distribution on top, such as Gentoo ebuilds, Void Linux packages, and even some more niche packaging spec files.

„Haare ab, Haare hoch, steil, ein Gebirge aus Haar, Haare wie Messer, die aus dem Kopf stechen.“ Eine jugendliche Punkerin spricht am Ende der DDR über ihr Leben und ihre Erfahrungen. Ihr älteres erwachsenes Ich kommentiert und reflektiert aus der Zukunft. Es geht um Kunst und Liebe, um Anarchie, um das Rumhängen mit Freunden, um das Baden in der Kiesgrube und darum, dass sie nicht Frau sein will, sondern Punk, aber immer wieder Frau sein muss. Durch die Ich-Figur gehen diverse politische Diskurse hindurch und kommen spielerisch zum Ausdruck. Noisiger Live-Sound unterstreicht die Wortspiele.

Building openSUSE Mirror(s) in Mauritius (osc25) 17:07

vor 11 Tagen17:07

17:07

At oSC23, I [presented](https://www.youtube.com/watch?v=abNBhLug2Ls) the challenges that we, a small community of openSUSE users, faced back home when building our first mirror in Mauritius. Two years later, I'm sharing updates on how we're expanding further and adding a second mirror in Mauritius to host more mirror content for the local community. We still face challenges, which I will share during this talk, and I hope it triggers a discussion around how we can further optimize and support mirrors for smaller economies. If we get things right, it can be a template for other countries that still do not feature on [mirrors.opensuse.org](https://mirrors.opensuse.org).

Who broke the build? — Using Kuttl to improve E2E testing and release faster (osc25) 26:09

vor 11 Tagen26:09

26:09

No one wants to be responsible for breaking the build. But what can you do as a developer to avoid being the bad guy? How can project leads enable their teams to reduce the occurrence of broken builds? In talking within our own teams, we discovered that many developers weren’t running sufficient integration and End to End tests in their local environments because it’s too difficult to set up and administer test environments in an efficient way. That’s why we decided to rethink our entire local testing process in hopes of cutting down on the headaches, heartaches, and valuable time wasted. Enter Kuttl. Connecting Kuttl to CI builds has empowered our developers to easily configure a development environment locally that accurately matches the final test environment — without needing to become an expert CI admin themselves. These days, we hear, “Who broke the build?” far less often — and you can too! Licensed to the public under https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de…

With the types of products and projects that we regularly work on many of us don't get alot of exposure to new fancy technology, this talk aims to give a quick introduction to one of these topics, web assembly. As some background, For the last year i've been helping to port Little Piggy Tracker (LGPT) a clone of the LSDJ audio software for Game Boy to various handheld devices. At the same time I saw a conference talk that was an introduction to web assembly, this prompted me to ask the ever dangerous question "how hard can it be?" It turns out the answer to that question was not that hard so this talk will go through a brief overview of webassembly followed by the process I went through to port my code along with some of the other challenges i've had porting LGPT to other devices.

Geographically Distributed Kubernetes Clusters (osc25) 20:21

vor 11 Tagen20:21

20:21

Distributed compute at scale is a bit complex back home in Mauritius - cloud service providers are literally an ocean away, and local policies have a history of hindering technological progress. To "bring the cloud home", so to speak, a small team of tech enthusiasts decided to build a Kubernetes (K3s) cluster distributed across the country, in a bid to drive down costs while boosting resilience and availability. This session goes over the challenges of setting up such a geographically distributed cluster on baremetal hardware, including fighting latency, connection issues, dynamic IPs, and distributed storage, all while keeping costs minimal. While not entirely technical in nature, this presentation will go over some of the very unique challenges of living on an island in Africa with regards to The Cloud and digital infrastructure in general.

Open Source is no longer just for software: (osc25) 28:03

vor 11 Tagen28:03

28:03

Open-source software has transformed the software industry, resulting in lower costs, greater security, and much greater flexibility for software developers and end users alike. The transparency provided by open-source software has improved security dramatically. Companies cannot hide back-doors in open-source software. Open solutions allow widespread review and testing, resulting in improved software quality and security. While there are a few open-source hardware projects, most notably RISC-V, most hardware remains proprietary and closed-source. Engineers developing new products often use chips that are black-boxes. This is particularly problematic when developing solutions using hardware secure elements, small security chips used in IoT devices, crypto hardware wallets, mobile devices, industrial control systems, and other small devices. Developers have no visibility into the implementation of these devices, and cannot validate their security. In this presentation we will cover: Challenges with closed source hardware secure elements: Our experience with closed source secure elements (and the problems we found) Benefits of open source/open architecture hardware secure elements: Transparency, trust, and auditability Rapid response to vulnerabilities Community collaboration and innovation Compliance & certification Get your devkit at the workshop or order here and start playing! :) https://145324096.hs-sites-eu1.com/samples-order-form Documentation and tools: https://github.com/tropicsquare Licensed to the public under https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de…

(Virtual Talk) Quality on Autopilot: Scaling Testing in Uyuni (osc25) 37:21

vor 11 Tagen37:21

37:21

How do you scale quality in a fast-moving open source project like Uyuni? In this talk, I’ll walk you through our journey adopting TestOps practices to bring automation, visibility, and resilience into our quality engineering process. We’ll explore how infrastructure automation with Terraform and Salt laid the foundation for consistent, on-demand testing environments. From there, we introduced test observability using Prometheus and Grafana to analyze historical trends and gain visibility into test behavior over time. A key part of our process includes tracking flaky tests and known issues through a custom system that connects our internal QE workflows directly with test reports. To accelerate feedback loops, we implemented smart test selection in Pull Requests, targeting only the affected components with relevant end-to-end tests. We also integrated synthetic monitoring of key product metrics into our daily pipelines, ensuring continuous insight into overall health. Thanks to designing our own DevContainers, we improved engineer's experience on their IDEs. We are also working on providing public AWS-based test reports reinforcing transparency. Our journey is a story of small, iterative changes that helped us align quality with development at scale.

What does "make opensource ecosystem secure one audit at time" mean (for you and for me)? (osc25) 26:36

vor 11 Tagen26:36

26:36

Ever wonder what goes on behind the scenes to keep your favorite open-source projects (relatively) secure? Spoiler alert: it's not magic (mostly)! This talk is a peek into the world of a security engineer who spends their days auditing code, hunting down vulnerabilities, and trying to make the open-source world a little less "Oops!" and a little more "Awesome!". We'll dive into: - What actually goes into a software audit. (Think less "spreadsheets," more "WTF is that?") - The thrill (and occasional horror) of vulnerability research. - Why this matters to you, even if you don't write code for a living. (Hint: it's about more than just avoiding the next big breach.) - How we, as a community, can all contribute to making open source safer – because, let's face it, we're all in this together. So, if you've ever been curious about the security side of open source, or just want to hear some war stories from the front lines, come join me! Let's talk about how we can make the open-source ecosystem more secure, one audit at a time. For you, for me, for everyone!
