Codetown ::: a software developer's community
Hello GatorJUG!
There are five courses coming up that will help you get in-depth training in some of today’s most important technologies for software engineers and developers. These courses are led by skilled trainers and can be taken anywhere with a reliable internet connection.
There's a lot of buzz about how JavaScript and the fantastic ecosystem is taking the web by storm. Have you wrapped your head around the new Java 8 features yet? Here's one way to find out a lot about HTML5, Java 8, Architecture, Node and React.
Software Architecture: From Developer to Architect
Live online training with Mark Richards on January 13th. This course will touch on both the technical aspects of software architecture as well as the soft skills of architecture, including architecture patterns, integration architecture basics, enterprise architecture basics, and soft skills such as how to think like an architect, make effective architecture decisions, and analyze architecture tradeoffs.

Implementing Hypermedia with Node and HTML5
Join Mike Amundsen for a live online training on February 9th. Implementing Web apps using the Hypermedia Style means creating services and clients that leverage the principles that make the Web so powerful: Functionality that relies on passing messages that contain Hypermedia Links and Forms. Unlike RPC Style web apps that depend on defining static function names and strong-typed argument lists, Hypermedia Style allows services to make promises about network-level formats (HTML, HAL, Collection+JSON, etc.) and application-level semantics (Accounting, User Management, Call Center Services, etc.).

Fundamentals of Java 8
Join O'Reilly authors Richard Warburton and Raoul-Gabriel Urma on February 16th for a day-long course where students will develop a firm working knowledge of the latest—and most groundbreaking—features in Java 8: lambdas, streams, and collectors. By the end of the tutorial, students will be able to put these features into practice in their jobs. They'll also be familiar with the cutting-edge programming tactics needed to produce functional code that is both flexible and concise.

React for Web Developers
Join Jonathan Stark for a live multi-day training starting January 7th. React, the popular open source library created by Facebook and Instagram, takes a new, component-based approach to building user interfaces. It’s very much about building reusable components. You simply express how your app should look, then React automatically handles all the UI updates when your underlying data changes.

Mobile HTML5 Training
Join Max Firtman for a multi-day online training starting February 1st. The Web is everywhere, including people’s pockets. The mobile Web now frequently dominates traffic, and Web tools like JavaScript, HTML, and CSS offer a familiar path to creating mobile applications. While there are challenges to supporting the vast array of devices, screen sizes, and application delivery approaches, the Web was built with diverse platforms in mind. Learn to build sites and applications that take full advantage of the latest in Web technologies.

Stephen Batifol discusses building and optimizing self-hosted, multimodal RAG systems. He breaks down vector search, nearest neighbor indexes (FLAT, IVF, HNSW), and the critical role of choosing the right embedding model. He then explains vLLM inference optimization (paged attention, quantization) and uses Mistral's Pixtral to detail multimodal large language model architecture.
By Stephen BatifolAt OpenAI's DevDay 2025, AgentKit and models GPT-5 Pro and Sora 2 were unveiled, enabling interactive software experiences directly within ChatGPT. This shift towards "apps inside ChatGPT" fosters collaboration and commercialization in conversations. Enhanced self-hosting options and robust SDKs empower developers and streamline workflows, positioning OpenAI at the forefront of AI innovation.
By Andrew HoblitzellMicrosoft has released Data API Builder (DAB) 1.6, expanding the open-source runtime’s capabilities for REST and GraphQL endpoints over Azure SQL, PostgreSQL, MySQL, and Cosmos DB. The new version introduces advanced HTTP header behaviours for better client-side control and a revamped logging subsystem designed to improve diagnostics and observability in both cloud and on-premise deployments.
By Edin KapićThe QCon AI New York 2025 schedule is now live for its Dec 16-17 event. Focused on moving AI from PoC to production, the program offers a practical roadmap for senior engineers & tech leaders. It addresses the real-world challenges of building, scaling, and deploying reliable, enterprise-grade AI systems, helping organizations overcome the hurdles of productionizing their AI initiatives.
By Artenisa ChatziouGitHub has introduced a new embedding model for Copilot, now integrated into Visual Studio Code. The model is designed to improve how Copilot understands programming context, retrieves relevant code, and suggests completions.
