🛠️ Pinokio, Sigstore, and more open tools to try this week

Docker’s Content Trust is on the way out. Starting August 8, signing certs for Docker Official Images will begin to expire — so what now? This quick guide breaks down what’s changing and what to know about Sigstore vs Notation before choosing your next image signing solution.

WHY WE ❤️ IT: When working with containers, one of the big security concerns is making sure the images you’re using are legit. Docker’s "Content Trust" feature lets users verify the authenticity of images so you can confidently deploy them to your Kubernetes clusters. Any change is important and something our community should be aware of.

Brandon Mathis takes us on a journey through computing history to explore whether AI-assisted coding is a true revolution or simply the next step in developer tools and what it means for your workflow.

WHY WE ❤️ IT: In this talk, Brandon takes the audience back to the 1880s census tabulator and speeds through decades of computing milestones—Grace Hopper’s innovations, NASA’s system architectures, and the rise of interactive IDEs and GUIs, and calls out key shifts in developer experience along the way.

Open source isn’t just part of the stack—it’s the engine driving the future of cloud, AI, and infrastructure. Atlantic.Net CEO Marty Puranik breaks down how open source fuels their tech today and why it’s the key to unlocking what’s next.

WHY WE ❤️ IT: We love the deeper look at how Atlantic.Net uses open source technology to open some of their core cloud services, and the 4 key areas of open source support based on his 31 years experience having built a business on open source foundations.

Born from frustration with Lotus 1‑2‑3 and the programming constraints of the era, As‑Easy‑As emerged as a powerful spreadsheet alternative—engineered by developers, tested with real-world data. This story is part of our interview series spotlighting the open source minds behind the tools that shaped modern computing and the limitations they overcame along the way.

WHY WE ❤️ IT: This is part 2 of a series sharing the story behind As-Easy-As, and the lessons learned along the way. We love the "shareware" business model explanation and the recounting as to how the company started.

In this conversation with Jessica Garson from Elastic, we explore how observability went from confusing concept to essential tool in her workflow. She shares how learning open telemetry helped her fix broken demos, debug faster, and build with more confidence. If you’re a Python developer wondering how to get started or a veteran looking for tips, this one’s for you.
