The Best of Java Shorts Show--Is Available on Github 📎

The JDD conference organizers asked me to record a short promotion of my talk, so I recorded the very first short. I've been recording (more than 800 and growing) Java shorts: (youtube.com/bienadam/shorts) daily, "from scratch" usually without any dependencies, build tools, or even compilation.

The talk "The Best of Java Shorts Show: 100 Snippets in 50 Minutes" at Devoxx 2024 Belgium was recorded with a selection of the most interesting or popular shorts:

I have received several requests for the source code and have published a selection (>100) of the snippets here: github.com/AdamBien/best-of-java-shorts

Live From Devoxx Belgium: Pure Java Enterprise AI/LLM Integration (EAI 2.0) 📎

This session was presented live at Devoxx Belgium:
From REST API and SDKs to langchain4j to fully managed cloud solutions to local integration with jlama and llama3.java of open source foundation models. In this session I will present architectures, ideas, hacks, and workarounds for integrating LLM with Java enterprise applications. I will illustrate the concepts with Java 21, Quarkus / MicroProfile code and integrate the latest Claude, ChatGPT, llama and AWS Bedrock models. Your questions will be given priority and answered interactively.

Live From Devoxx Belgium: The Best of Java Shorts Show: 100 Snippets in 50 Minutes 📎

I picked the most interesting youtube.com/bienadam/shorts and presented them live at Devoxx Belgium.
How to: run Java as a shell script, run a Java app without compiling, print an emoji, run an HTTP dev server, use libraries without compiling, colorful logs, access LLMs,run timer jobs, access the clipboard, implement a file watch, main in interfaces, easy file parsing (...) and ~100 other popular Java snippets from youtube.com/bienadam/shorts. No builds, no Maven, no dependencies, just javac and Visual Studio code.

Abstract Classes vs. Interfaces, Performance Benchmarking, JMH, Lambdas and Databases--127th airhacks.tv 📎

The 2024.10 / 127th edition of airhacks.tv with the following topics:
"String.join() is 30% faster than Collectors.joining(), JMH not always necessary for high-level benchmarking, interfaces slightly faster than abstract classes but the difference is negligible, Quarkus requires no installation - just use the POM file, Quarkus tests are integration tests and should be used sparingly, use shutdown hooks or @PreDestroy for clean connection closure in Lambdas, GraalVM shines in CLI tools and polyglot applications, simple export method for Java version management, JavaFX on mobile is challenging but viable with Gluon, EJBs and some Java EE concepts are outdated, but interceptors and dependency injection are still relevant"

Performance Abstract classes vs. Interfaces, Lambda and DB Connections, JMH--Questions for 127th airhacks.tv 📎

Questions and topics for the 2024.10 / 127th edition of airhacks.tv with the following topics:
  1. performance: abstract class vs. interface Hi, I got an interview question as to which one is faster Abstract class or Interface ? Can you explain please. What is Faster: String.join or Collectors.joining?
  2. DB connections and lambda shutdown
  3. performance measurement with or without JMH: "PLEASE use the microbenchmark harness in future videos. I have the impression, that this suggests that performance measurements with after-minus-before is a good idea." from: What is Faster: String.join or Collectors.joining?
  4. the 100-episodes back time machine. Questions from: 27th airhacks.tv:
    "Interceptors and Dependency Injection Singleton EJBs, CDI and concurrency BCE in Eclipse and can Boundary communicate with Entity? Stateful EJBs vs. SessionScoped"
