Hello OrlandoJUG!
This month we have Dave Moskowitz in from Sarasota for a fascinating talk.
Here's the abstract for the presentation. There is a possibility of massive amounts of pizza!
Genetic programming (GP) is a class of nature-inspired AI algorithms that aims to automatically generate a population of computer programs to solve a target problem where the solution is unknown. By defining a fitness function (a high-level statement of the problem) and applying principles of Darwinian evolution (mating, survival of the fittest), GP breeds a population of computer programs that achieve a higher level of fitness and come closer to an optimal solution over time.
GP is most applicable to problems without deterministic solution. An example of such a problem is stock market prediction. There is no canonical theory on how to "beat the market". The most widely accepted belief regarding this question is stated in the efficient market hypothesis (EMH), which holds that no method can consistently beat the overall market, However, there is conflicting research from both the economic and AI communities regarding the validity of this hypothesis. While most research appears to deny the possibility of consistently beating the market after factoring in transaction costs, recent no transaction cost trading platforms, such as Robinhood, as well as more powerful and available data processing capabilities, make beating the market more in reach than ever.
The presentation will begin with an introduction to genetic programming, focusing on the more common tree-based (LISP) representation. Other approaches to GP, as well differences between genetic programming and genetic algorithms will also be discussed.
A Java based GP system, developed by the speaker, will be used to illustrate some basic GP examples. Finally, the genetic programming algorithm will be run on the S&P 500 index using current market conditions to see what it predicts for the immediate future.
This talk will convince you that genetic programming is essentially an approachable technique that can be applied towards many problems in the area of numeric optimization, prediction, design, or just about anything else you can do in a computer program.
About the Speaker:
David Moskowitz is a Market Data Architect at Ned Davis Research in Venice Florida where he develops and maintains web and REST based financial data delivery systems. He is currently a PhD candidate in Computer Science at Nova Southeastern University and is also the former chairman of the Sarasota Java Users Group.

Netflix engineers describe an internal automation platform that migrates nearly 400 RDS PostgreSQL clusters to Aurora, reducing downtime and operational risk. The platform coordinates replication, CDC handling, controlled cutover, and rollback, while supporting service teams in a self-service migration workflow.

Patrick Debois discusses the evolution of software engineering in the age of AI. He shares four key patterns: transitioning from producer to manager, focusing on intent over implementation through spec-driven development, moving from delivery to discovery, and managing agentic knowledge. He explains how these shifts redefine seniority, team roles, and the future of the DevOps workflow.

This week's Java roundup for March 2nd, 2026, features news highlighting: the GA release of Apache Solr 10; point releases of LangChain4j, JobRunr, Multik and Gradle; maintenance releases of Grails and Keycloak; Devnexus 2026; and Pi4J joining the Commonhaus Foundation.
By Michael RedlichIn this episode, Thomas Betts and Sam McAfee discuss how AI hype is reshaping organizational behavior, why many companies struggle with experimentation, and how unclear decision structures create friction. They explore psychological safety and mindful leadership as essential foundations for healthier, more effective engineering cultures.

System changes are the primary driver of production incidents, making change-related metrics essential reliability signals. A minimal metric set of Change Lead Time, Change Success Rate, and Incident Leakage Rate assesses delivery efficiency and reliability, supported by actionable technical metrics and an event-centric data warehouse for unified change observability.
