@bsideup I just checked. They are fairly uncommon for Canon EF mounts (unfortunately), which means I can't get it. But your photos are very convincing :-)

@maeddes Yep! I wanted to try it because of the physical aperture ring that I don't have on my Sony 85mm 1.8 but was very positively surprised with its IQ!

I'm probably overhyping but omg! My new favorite lens 😀

Newsflash: Devoxx UK is not your average conference! We go above and beyond to create a happy, inclusive vibe so you’ll leave not only having learned a LOT, but with a big smile on your face too. Come and see what we mean. devoxx.co.uk 6th & 7th May | London

Observability & Flags If you can't see it, you can't fix it: 🔹 @maeddes & @tiffanyfayj - Hello World, Meet the Spanimals: Observability for Beginners. 🔹 @CarlyLRichmond - Observing AI Applications with OpenLit. 🔹 Simon Schrottner - Feature Flagging Without the Pain.

My talk on #YOW2025 🐨🦘🪃🇦🇺 with special bits of @maeddes @simonbrown @mfeathers @royvanrijn inside Thanks to the amazing team for an amazing time! blog.frankel.ch/yow-2025/

@Rosenlippengirl @yanashin18618 😅

@maeddes @yanashin18618 😊

I might quit X soon. I might turn it into an account just for checking TL. そろそろX辞めるかも。ＴＬを見る専アカウントにするかもしれないです。

@cat_edelveis so cool. Enjoy it!

🍃 What's (new) with Spring Boot and Containers? by @maeddes / Eva Panadero @ Spring I/O 2025 ▶️ Video: youtu.be/nesRmaUi4Ts 🔗 Slides: speakerdeck.com/maeddes/whats-… 🛠️ Repo: github.com/maeddes/spring… #springio25

@piotrprz @Sharat_Chander Happy Birthday from me as well! 🥂🥳

@Sharat_Chander Wait a sec! Usually both twins have their birthday the very same day. So... HAPPY BIRTHDAY TO BOTH OF YOU! (and all the other days too!)

War wie immer eine Freude dir zuzuhören! Sehr guter Vortrag über Container und Spring Boot von @maeddes auf dem #jfs2025

@sergialmar @spring_io Camp Nou? 🤩

The venue for @spring_io 2026 is now secured! After visiting several venues and cities, we have a new home for next year's edition.

@sKriemhild @VoxxedCERN @Docker @java @Paketo_io @Devoxx 🤗

@maeddes @VoxxedCERN @Docker @java @Paketo_io @Devoxx Catchy title, great presentation! I'm not surprised

For reasons I don't understand my video from @VoxxedCERN got as many likes and views in a day that I normally get within a year. Hope you like it, too 😇 Happy weekend! @Docker @java @Paketo_io @Paketo_io @Devoxx #container #build #voxxed youtube.com/watch?v=HFhIqf…

🚀 𝐎𝐎𝐏 2025 - 𝐃𝐚𝐲 4🚀 Today marked the fourth and final day of @oop_conference 2025. So many inspiring talks, thought-provoking discussions, and deep dives into the future of software engineering. Here are some of my key takeaways from today's sessions: 🎤 Effektives Platform Engineering – @markus_zm #PlatformEngineering is a game-changer for modern software development, enabling teams to move faster while ensuring security and compliance. KEY TAKEAWAYS: 💡 The CNCF Maturity Model provides a structured approach to evolving internal developer platforms. 📊 Four maturity levels across five dimensions help teams optimize their platforms. 🛠️ Practical examples showcased how organizations can assess and improve their platforms effectively. 🎤 Codespaces, Gitpod, Devpod ... what cloud-based IDEs can do – @maeddes Cloud-based development environments are rapidly reshaping the way we build software. KEY TAKEAWAYS: 💡 #Gitpod, #GitHub #Codespaces, and #Devpod are revolutionizing development workflows. 🚀 Instant setup means faster onboarding, better collaboration, and seamless CI/CD integration. 🖥️ Live demos showed how to develop and deploy polyglot applications in a fully containerized environment. 🎤 GenAI-Bot-Entwicklung: Challenge Accepted – Tessa Pfattheicher & Lars Orta #GenerativeAI powered chatbots are not just another software project. They introduce new challenges for PO’s, BA’s, and developers alike. KEY TAKEAWAYS: 🤖 "Garbage in, garbage out" – #DataQuality is crucial for GenAI success. 🧩 AI projects require a shift in mindset: traditional deterministic testing doesn’t apply. 🔄 Experimentation & user feedback loops are key to refining AI-driven experiences. 🎤 From Perfect Surfaces to Virtual Twin Experiences – Sven Havemann @Dassault3DS has evolved far beyond CAD software, pioneering #VirtualTwin Experiences. KEY TAKEAWAYS: 🚗 Class A surfacing techniques define the visible design of modern cars. 🌍 #3Dtechnology is now integral to managing the real world through simulations. 🔗 Dassault Systèmes is much more than just CATIA – it’s shaping the future of digital twins across industries. 🎤 From Zero to PROD in 20 Minutes? Securely! – @MirkoQuarg & Kay Thriemer Deploying #BSI -compliant cloud infrastructure for critical sectors (KRITIS) is no trivial task! KEY TAKEAWAYS: 🔐 Policy enforcement with #Kubewarden, OPA/ #Gatekeeper, #Kyverno ensures compliance. 📊 Observability is key – #OpenTelemetry, #Grafana, #Elasticsearch power secure monitoring. 🚀 DevOps best practices like #GitOps (#ArgoCD, #Flux) & hardening (#AppArmor, #SELinux) are essential for secure cloud setups. 🔥 Final Reflections from OOP 2025 👉 OOP 2025 reinforced one thing: Innovation thrives when we break silos. A huge thanks to the speakers, organizers, sponsors and attendees for making OOP 2025 an unforgettable experience! 🚀 Until next time! 👋 #OOP #SoftwareArchitecture #PlatformEngineering #DevOps #Cloud #AI

@royvanrijn Why do you use "him" so often in your memes? I mean I totally get your point ... it's just ... I already have to see him way more often than I want already anyways

BREAKING: Trump has imposed 25% tariffs on the import of all Java libraries, with an extra 10% on each Maven dependency. He commented: “…and America can no longer use the word POJO, it sounds very Mexican.”
