An airhacks.fm conversation with Steve Hannah about:

meeting Steve Hannah at JavaOne years ago via Codename One, the Apple IIGS as a first computer, floppy disk games and Bob Whitehead's Hardball!, starting web development in 1997 with Perl and CGI, the O'Reilly Perl camel book, CGI security issues and the parallel to LLM tools, choosing Java Servlets over CGI for startup-time performance, moving to PHP for quick and dirty web development, PHP evolving toward enterprise patterns with Zend, Symfony and Laravel, PHP at Cloudbeds as a serious enterprise language, Facebook compiling PHP with HipHop, connection pooling and data sources impressing PHP developers, convergence of ideas across Java, JavaScript classes and React moving from object orientation to hooks, web components as JavaScript classes with properties, TypeScript versus JavaScript with JSDoc types in VS Code, LLMs reducing the importance of web frameworks that follow standards, porting React to Java on TeaVM using Claude, Flash and ActionScript for rich interfaces before HTML5, key frames hiding the full code base in Flash, VisualAge for Java showing only methods and printing source to understand it, the Xataface open-source PHP/MySQL CRUD framework started in 2005, the Dataface to Xataface rename, FileMaker as a low-code database tool and its licensing constraints, joining Codename One as the first hire in 2012, front-end Java versus back-end Java culture at JavaOne, the extreme GUI makeover Swing session, coding with LLMs in 2026 using Claude Code and Codex, building a personal Swing-based IDE for multi-repo multi-branch agentic workflows, work trees and terminal-organized agent sessions, a possible Swing and JavaFX revival because they ship with Java and LLMs know them, Java 25 source-mode shebang scripting replacing Python scripts, Java shipping more built-in functionality than Python for regular expressions and dependencies, Ruby versus Python popularity, LLMs understanding Java (~87%) better than JavaScript (~60-70%), type safety enabling LLM self-correction, grounding LLMs with MicroProfile and Jakarta EE normative specifications, the JSR normative language read by LLMs, business annotations and rich JavaDoc and package-info improving LLM output, reducing external dependencies so LLMs avoid decompiling JARs, token savings from standards-based Java, AWS Bedrock for stable and private Claude access with Claude Code, Quarkus on AWS Lambda with cold starts and Provisioned Concurrency, pinging a AWS Lambda every minute within the free tier to avoid cold starts, cost calculation for Quarkus on Lambda with 2 GB RAM, constructions.cloud Quarkus serverless CDK examples, Google Cloud Run versus AWS App Runner, AWS Lambda and Azure Functions, AWS CDK as infrastructure as code in Java, JDeploy for packaging and distributing desktop apps, the AIRails.dev skills site and the microprofile-server skill, zero-dependency Java scripts and agents, migrating a WordPress blog to a Jekyll static site with Claude
