Beyond Code: How the LKMP Helped Me Grow as a Developer and Community Member - Luis Felipe Hernandez, Independent

Wednesday August 27, 2025 11:00 - 11:40 CEST

TBA

The Linux Kernel Mentorship Program (LKMP) was more than just a chance to contribute to open source—it was a turning point in my career and technical growth.

Join me as I share how this experience helped me land my current role, give back to the Linux community, and inspired me to take a more active role in my local community—organizing events, mentoring, and sharing knowledge.

Speakers

Luis Felipe Hernandez

Sr Software Engineer | Adjunct Professor, Beacon Hill | Rollins College

Luis Felipe Hernandez is a Senior Software Engineer currently residing in Orlando, FL. Outside of work he is a Linux Kernel Mentee and aspiring Open Source developer.

Applying DevRel Foundation Resources To Application Security - Jayson DeLancey, Semgrep

Wednesday August 27, 2025 11:55 - 12:35 CEST

TBA

The Developer Relations Foundation is a new part of the Linux Foundation to advance the professional practices of Developer Relations. As a Manager of the Resources Working Group we're on a mission to collect open-data resources like Personas, Events, and Tools that any practicing Developer Relations role can use to accomplish their outreach and community goals.

This session will share how we kick-started the working group and then examples of using these resources for my own role on the free open-source tool Semgrep for engaging with developer communities to make software more secure.

Speakers

Jayson DeLancey

Head of Developer Relations, Semgrep

Jayson is a manager for the Resources Working Group of the Developer Relations Foundation and is Head of Developer Relations for Semgrep, an open-source static code analysis tool.

Building a Solarpunk Web: Open Source for a Sustainable Digital Future - Mike Gifford, CivicActions

Wednesday August 27, 2025 14:10 - 14:50 CEST

TBA

We’re in a climate crisis—and the web isn’t off the hook. From energy-hungry AI to bloated, resource-intensive websites, our industry’s digital footprint is growing fast.

This talk explores how we can flip the script using open source tools to measure and reduce the carbon impact of our work. We’ll dive into practical ways to assess emissions, spotlight FOSS projects leading the way, and share actionable steps every open source project can take to help cut down energy use.

Together, we can build toward a solarpunk future—one where technology empowers a healthier planet and better lives for everyone.

Speakers

Mike Gifford

Open Standards and Practices Lead, CivicActions

Mike Gifford is an open standards and practices lead at CivicActions and a thought leader on digital accessibility in the public sector. He is also a W3C Invited Expert and recognized authoring tool accessibility expert.

Why Quantum Safe Encryption Is the Next Y2K, and How To Be Prepared - Joe Winchester, IBM

Wednesday August 27, 2025 15:05 - 15:45 CEST

TBA

Client server computing relies on encryption algorithms to ensure that data sent across networks cannot be read, or faked, by untrusted parties. This is the rock on which financial computing works in a business to customer environment, as well as how data at rest is protected from malicious prying eyes reading our personal data.

This talk will cover the basics of how Diffe-Hellman encryption works, how symmetric and asymetric keys operate, as well as how all of this will soon become unsafe because of quantum computing. As well as showing the audience the basics (no maths degree required) this talk will show how quantum safe encryption is able to address this, and how folks can get wise and get started.

From Radar Echoes To Real-Time Recognition: Deep Learning on Another Planet an Open Source Workflow - Viktor Somogyi, Netwerk / HUN-REN / ESA

Wednesday August 27, 2025 16:20 - 17:00 CEST

TBA

What happens when you combine real radar images of Venus, a bunch of volcanoes, and deep learning? In this talk, I’ll walk you through a fully open-source machine learning pipeline that turns extraterrestrial data into structured scientific insights. Our goal is to automatically recognize geological formations like craters, ridges, or volcanoes on radar imagery — a bit like Google Maps, but for another planet.

The workflow starts with hand-labeled GeoJSON data in QGIS, then moves through preprocessing, training, and testing using PyTorch, scikit-learn, and AWS SageMaker — all running on Linux-based cloud infrastructure. This ESA (European Space Agency) funded scientific project is coordinated by the Hungarian Research Network (HUN-REN), and every part of it is powered by open tools and services.

If you're curious about how Linux, Python, and AWS can work together to map alien surfaces, this session will take you there — without leaving Earth.
