I didn't mean to make you feel bad, I know how busy you must be. It's just we could do more to promote this site. Does the twitter thingie work for you?
Hey Mike! Conference is awesome. Hoping to post talks as soon as they're up. My talk os tomorrow! Also that's great I would love to hear his talk!!! We're doing a lot with AOP and metaprogramming
Hi Michael, nice to meet you. When is the next meeting? I may need some time to prepare and practice. The talk I'm writing outlines how we use Docker with the Gradle build tool to empower local development of cloud applications. Examples will include Grails and Spring Boot.
So cool Jim Clarke will be having a talk at OJUG! What are the chances his talk might be recorded? I have his book and am a huge fan. Love to get his view on the continued value in native development.
TornadoFX workshop should be recorded for tomorrow at Chicago GDG: I'll be sure to post in Kotlintown!
Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.
When you create a profile for yourself you get a personal page automatically. That's where you can be creative and do your own thing. People who want to get to know you will click on your name or picture and…
Airbnb has redesigned its identity system to support privacy-first social features in Experiences. The platform introduces context-specific profiles that separate global user identity from externally visible profiles, preventing cross-context linkage. The migration leveraged automated auditing, manual validation, and AI-assisted refactoring to enforce correct identity usage across services.
JEP 533, Structured Concurrency, has reached integrated status for JDK 27. It refines exception handling and type safety in its API, particularly focusing on exception flow with a new ExecutionException type. Changes include an updated Joiner interface and a new open overload for easier configuration. The steady evolution signals ongoing development as feedback shapes the API.
Paulo Arruda discusses Shopify’s evolution in AI adoption, moving from simple chat tools to a sophisticated swarm of specialized agents. He explains the transition from massive "all-in-one" prompts to lean, narrow-focused agent microservices that slash task times from hours to minutes. He also shares a future-looking hypothesis on using filesystem-based adapters to solve context bloat.
Backlogs in distributed systems are arithmetic problems, not mysteries. This article provides practical formulas for calculating backlog drain time, sizing consumer headroom, and setting auto-scaling triggers. It covers key failure modes — retry amplification, metastable states, and cascading pipeline bottlenecks — plus when to shed load instead of draining.
Grafana Labs has launched Pyroscope 2.0, a rearchitected open-source continuous profiling database. This version improves storage costs, query performance, and operational complexity. Key changes include single write paths for profiles, stateless query processing, and enhanced capabilities for profiling data. It supports the OpenTelemetry Protocol, aligning with current trends in observability.

Thanks so much for the birthday wishes. I know it's so late getting back to you but I don't check this website very often.
Thanks for the invitation and the birthday wishes, Mike!
Thanks. I'm interested either way (either 10/25 or the rescheduled day).
Sure Mike. I can do that

Thank you MIchael!
Thank you Mike for making me a part of this group. I feel very welcomed. Looking forward to learn and share!
Thanks Michael, to have me in the group!
I think I’d want to attend a few meetings to get a flavor for the group before jumping into a speaking role…
Thanks Michael for adding me in OJUG
I'm excited to attend events on Java related technologies
Thanx Michael, great to be here
