the benefits of using pure Java for build files and the flexibility it provides,
the speed of bld and the underlying Java compilers,
ideas for future improvements and features in bld,
the philosophy behind bld and its focus on simplicity and developer productivity,
the potential for using bld as a scripting tool and automation platform,
the extension mechanism in bld and how it leverages the builder pattern,
the performance gains of using bld over traditional build tools,
the aesthetics and user experience of bld,
the history of Java compilers and the evolution of Java desktop applications

An airhacks.fm conversation with Dmytro Liubarskyi (@langchain4j) about:
Dmytro previously on "#285 How LangChain4j Happened",
discussion about ONNX format and runtime for running neural network models in Java,
using langchain4j library for seamless integration and data handling,
embedding models for converting text into vector representations,
strategies for handling longer text inputs by splitting and averaging embeddings,
overview of the retrieval augmented generation (RAG) pipeline and its components,
using embeddings for query transformation, routing, and data source selection in RAG,
integrating Langchain4j with quarkus and CDI for building AI-powered applications,
Langchain4j provides pre-packaged ONNX models as Maven dependencies,
embedding models are faster and smaller compared to full language models,
possibilities of using embeddings for query expansion, summarization, and data source selection,
cross-checking model outputs using embeddings or another language model,
decomposing complex AI services into smaller,
specialized sub-modules,
injecting the right tools and data based on query classification

An airhacks.fm conversation with Alfonso Peterssen (@TheMukel) about:
discussion about Alfonso's early programming experience and participation in the IOI competition, studying computer science and functional programming with Martin Odersky, internships at Google and Oracle Labs working on compilers and the Espresso project implementing a JVM in Java,
espresso mentioned in "#208 GraalVM: Meta Circularity on Different Levels", "#194 GraalVM, Apple Silicon (M1) and Clouds", "#167 GraalVM and Java 17, Truffle, Espresso and Native Image" and "#157 The Ingredients of GraalVM",
porting LLVM to pure Java in one class, integrating Large Language Models (LLMs) in Java by porting the LLAMA model from C to Java,
GPU acceleration with tornadovm,
TornadoVM appeared at "#282 TornadoVM, Paravox.ai: Java, AI, LLMs and Hardware Acceleration",
performance of the Java port being within 10% of the C versions, potential huge opportunities for integrating AI and LLMs with enterprise Java systems for use cases like fraud detection, the Java port being a 1,000 line self-contained implementation with no external dependencies, the need for more resources and support to further develop the Java LLM integration,
the llama2.java project
