I've done an unusual number of mentoring calls this week, and one thing I'd like to remind everyone is, you are enough, and you can't forget how far you've come. You're most likely in the best position you've ever been in to build on top of everything you've done until this point.

The website I frequently buy my KN95 Powecom masks from, Bonafide Masks, is having a Black Friday sale with the coupon code BFM35. It's worth picking up extra masks. The headstrap models also come in several colors and don't cause my glasses to fog after I adjust the noseband for a better fit.

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?

Aww thank you! I just counted the other day and since our first talk together at #KubeCon EU 2023 we have had 11 sessions together! I feel so fortunate to have had such an opportunity. Here’s to hopefully many more! To everyone else: I highly recommend @maeddes.bsky.social as a cospeaker!!

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. github.com/FasterXML/ja... www.cowtowncoder.com/blog/archive... @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

This is not a drill! What free graphical diff/merge tool would you recommend for macOS that works with git difftool --dir-diff? I've been using meld since forever but it was never officially supported and the third-party build seems discontinued and broken on the latest macOS.

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

Big idea: you can call any functions (including the core API, any you write/install) from the dagger CLI or from code!
