Don't panic: Rsync mistakes, AI chaos, and DOScember

Welcome to edition #42 of the We ❤️ Open Source newsletter!

Don't panic! We've got answers, even if they're not the answer to everything. This week we're exploring the context engineering that makes agentic AI actually work, why FreeDOS is thriving 30 years later during DOScember, and how Dagster scaled documentation to 16,000 monthly questions without hiring more people.

We're also featuring Netflix engineer Ben Ilegbodu on the We ❤️ Open Source podcast sharing why hands-on learning beats theory in the age of AI, plus Learn Linux TV's essential rsync safety tips that could save your data.

As always, our goal is to raise your open source IQ and share the stories of the people shaping the open source world—through content made and curated by real humans.🙂

This week we'll look at...

Data Engineering Training for an AI-powered future

Our friends at Build Carolina are offering an 8-week, part-time, live virtual course that will teach you how to collect, clean, and transform data so it can power AI, machine learning, and analytics. The course will give you practical skills, confidence, and the knowledge to thrive in today’s AI-enhanced tech landscape.

Articles

Ever tried building an AI agent that collapses the moment it meets real-world data? You’re not alone. This post explores why unstructured data, from Slack threads to messy system logs, is often the missing context that determines whether agentic AI works or fails. Learn how modern context engineering turns that chaos into clarity and why developers who master it will have a serious edge in 2026.

WHY WE ❤️ IT: We love the focus on context engineering, but we love the final section describing why it thrives in an open source ecosystem even more. There is an open source imperative indeed.

December is DOScember, and we're celebrating FreeDOS, the open source DOS that's been thriving since 1994. FreeDOS has evolved into a modern command-line powerhouse with dozens of tools, network support, and compatibility with classic applications. Learn why this 30-year-old project is still relevant, actively developed, and ready for both legacy apps and new experiments.

WHY WE ❤️ IT: There are multiple ways to get involved mentioned in the article and actively participate, including downloading the monthly test release, testing the most recent updates, and joining the email list.

Your open source project is growing fast, but your documentation team isn't. Dagster faced this exact challenge and solved it with smart information architecture, AI tooling, and a custom assistant that now handles over 16,000 community questions monthly. Learn how they scaled docs without scaling headcount, empowered contributors with clear guidelines, and turned documentation into a competitive advantage.

WHY WE ❤️ IT: We recognize the challenge of creating good documentation, and the value of it. This article and recording serve as a wonderful case study that can help many in our community.

Digital sovereignty isn't a compliance checkbox—it's a strategic imperative. As vendor lock-in becomes a critical risk and privacy regulations tighten, organizations are using open source to take back control of their infrastructure and data. Learn why true independence means transparent code access, flexible deployment, and the freedom to choose your own path without vendor constraints.

WHY WE ❤️ IT: This article does a great job of describing how open source is the key to digital independence. What's not to love?

What's in your technology toolbox?

One wrong rsync command could wipe out your backup instead of creating it. Jay from Learn Linux TV, reveals the essential safety flag every Linux admin needs, plus the archive mode trick that preserves file metadata. These tips will save you from painful transfer mistakes.

From the We âť¤ď¸Ź Open Source Podcast

Can AI really make you a better developer? Netflix engineer Ben Ilegbodu says yes...if you’re willing to get hands-on. In this We Love Open Source podcast, Ben shares how curiosity, teamwork, and real-world experimentation can help you grow faster and build smarter in the age of AI.

Wrap Up

If you've made it this far (thank you!), check out everything we do, our YouTube channel with 1000's of open source talks, the many meetups we host around the southeast and NYC, the All Things AI spring event we co-host, and of course All Things Open, the largest open source tech conference on the US east coast.

We hope you learn something new this weekend!
