I had a great time working with @nancychauhan.bsky.social for our @devrelcon.bsky.social talk, The Art of Vulgarization: Making Complex Ideas Accessible. Thanks to the organizers, staff, & folks who came to our talk.

Also Nancy is awesome and if you're hiring, please reach out to her!

I am also incredibly thankful to have been able to see so many beautiful places this year. Another big thanks to friends for joining me or letting me join adventures and/or to conferences for giving me more opportunities to see the world.

Happy Thanksgiving!🍁

This year has been a very rough year, but I’m especially thankful for my family & friends for making it much better than it could have been. I am also thankful for the conf organizers/volunteers for the opportunities to connect, learn & teach others.

What’re you thankful for?

Thanks!!

Yeah I didn’t see any animals at all when in Park City. But wow with all that I’m surprised you didn’t see more. Definitely go to Antelope Lake sometime! There were bison everywhere. I imagine Moab/the parks were beautiful though!

Today is my birthday so I wanted to share some pretty nature with everyone else; here are some photos I took at Antelope Lake in Utah after #KubeCon!

What is #Jackson?
It’s a library
- Open Source
- #Java
- #JSON

What does Jackson do?
First & foremost: Read JSON as Java Objects; write Java Objects as JSON.

@cowtowncoder.bsky.social at the #Seattle Java User Group (JUG)
Photo with Tatu and slide 1. Intro: What is Jackson? Jackson is a ... Library Open Source (Apache License) Java (with JVM "friends") JSON (tothers) that is • Modular (architecture, design, development, implementation) • Feature-Rich (functionality you won't find anywhere else) Highly Configurable & Extensible Widely-Used ("everybody uses Jackson! Even if unknowingly") 1. Intro: What does Jackson do? First & foremost: (raison d'etre - "mission statement?") Read JSON as Java Objects; write Java Objects as JSON. but also • Framework integration • JAX-RS (Jersey, RESTeasy, ...), Quarkus, Spring Boot • Works with many popular libraries (via modules) • Eclipse-collections, Guava, Hibernate, Joda ... Immutables, Lombok ... • Data formats other than JSON (10+) • from Avro to YAML • Other JVM languages • Kotlin & Scala modules; Clojure (cheshire, jsonista) 3. Current: Processing Model recap Since 1.0: "Three Ways to Process JSON" (many libraries offer just one) • 3 Processing Models Streaming: read/write JSON as JsonToken streams - foundation • Tree Model: read/write DOM-like (JsonNode) - JSON-centric • Databind: read/write as Java Objects (POJOs, Records,JDK, 3rd party) - Java-centric Model interaction: • Tree Model, Databind are built on Streaming (read/write using parser/generator) • Only streaming is format-specific (JSON vs XML vs CSV parser/generator) • Seamless, efficient conversions between models, as necessary

Thought so! But like, Angels landing or something else?

Haha yeah I wanted to go but needed to do it after the conf due to talk prep, then backed out with the snow. Antelope Lake was awesome though.

Need to go someday though.

Big congrats to Max Körbächer, @grabnerandi.bsky.social, and Hilliary Lipsig for their book Platform Engineering for Architects and @lizrice.bsky.social for her many books such as Learning #eBPF. I’m looking forward to reading these and learning more after #KubeCon #CloudNativeCon!

Crazy to think it has been 9-10y since my first #dockerselfie with @shykes.bsky.social. Maybe it’s a #daggerselfie now.

Check out the awesome #Docker shoes!

Learning about Dagger, “a programmable tool that lets you replace your software project's artisanal scripts with a modern API and cross-language scripting engine.”, from Jeremy Adams #appdevelopercon #kubecon #cloudnativecon

Check out docs.dagger.io/quickstart/
Why dagger? API first, functions, modules API first Core API: containers, directories, files, git, services, sockets, secrets, cache Functions extend the API Big idea: you can call any functions (including the core API, any you write/install) from the dagger CLI or from code!
