observability as a tool for early issue detection and better code design,
the importance of continuous observability and reducing mental effort,
Digma's elevator pitch and data science approach,
the changing testing pyramid and the benefits of test containers,
"#103 Unit Testing Considered Harmful",
the cost and value of different types of tests,
optimizing lambda costs and performance,
linking System Tests to traces from quarkus JVMs,
Digma's architecture and deployment options, recent features and improvements in Digma,
the impact of observability on productivity and shorter feedback loops,
AWS Lambda Power Tuning,

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 Jonathan Ellis (@spyced) about:
Jonathan's first computer experiences with IBM PC 8086 and Thinkpad laptop with Red Hat Linux,
becoming a key contributor to Apache Cassandra and founding datastax,
starting DataStax to provide commercial support for Cassandra,
early experiences with Java, C++, and python,
discussion about the evolution of Java and its ecosystem,
the importance of vector databases for semantic search and retrieval augmented generation,
the development of JVector for high-performance vector search in Java,
the potential of integrating JVector with LangChain for Java / langchain4j and quarkus for serverless deployment,
the advantages of Java's productivity and performance for building concurrent data structures,
the shift from locally installed software to cloud-based services,
the challenges of being a manager and the benefits of taking a sabbatical to focus on creative pursuits,
the importance of separating storage and compute in cloud databases,
Cassandra's write-optimized architecture and improvements in read performance,

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
