Codetown ::: a software developer's community
Last nights OJUG meeting was great. Beth and Tracy did an amazing job of setting things up in the room and the presentation was wonderfully entertaining and insightful. It was spectacular and informative, what more could you ask for? Anyone who was unable to come certainly missed out, but maybe next year we'll have them give this presentation again. You never know.
Tracy provided us with a wealth of knowledge in terms of how to be recruited. His presentation on Working WIth Recruiters…

Confused? Probably, if…

Hi folks,
I've mentioned MySchedule before during the Quartz presentation at OJUG. I have released myschedule-1.1.2.war now. It's not that pretty, but it's fully functional. It deploy a fully working version of a In-Memory Quartz scheduler with web UI that can easily manage it.
If you are interested in Quartz, give it a try here http://code.google.com/p/myschedule. I wrote a mini UserGuide with here…

Pinterest Engineering cut Apache Spark out-of-memory failures by 96% using improved observability, configuration tuning, and automatic memory retries. Staged rollout, dashboards, and proactive memory adjustments stabilized data pipelines, reduced manual intervention, and lowered operational overhead across tens of thousands of daily jobs.

Franka Passing discusses the architectural shift of Duolingo’s 500+ backend services to Kubernetes. She explains the move toward GitOps with Argo CD, the transition to IPv6-only pods, and the "cellular architecture" used to isolate environments. She shares "reports from the trenches" on managing developer trust, navigating AWS rate limits, and productionizing early adopter services.

How can you focus in a sea of results from a large regression test suite? This article describes a stochastic approach that relies on some degree of redundancy in your CI regression test set. This approach does not guarantee you will catch every bug every time, but it gives you your best bet of not missing the subtle signatures of all the bugs uncovered by your CI regression test suite runs.
By James Bornefelt WestfallIn this episode, Thomas Betts and Adi Polak talk about the need for context engineering when interacting with LLMs and designing agentic systems. Prompt engineering techniques work with a stateless approach, while context engineering allows AI systems to be stateful.

A 600-run benchmark by Ruby committer Yusuke Endoh tested Claude Code across 13 languages, implementing a simplified Git. Ruby, Python, and JavaScript were the fastest and cheapest, at $0.36- $0.39 per run. Statistically typed languages cost 1.4-2.6x more. Adding type checkers to dynamic languages imposed 1.6-3.2x slowdowns. Full dataset available on GitHub.
