The author discusses the transformative impact of AI on programming, highlighting how advanced language models can now handle substantial coding tasks with minimal human intervention. While acknowledging the potential for job displacement, the author emphasizes the importance of adapting to these changes and using AI as a tool to enhance creativity and productivity in software development.

• Modern LLMs can now autonomously complete substantial, non-trivial coding tasks that previously required significant human effort, marking a real shift rather than incremental improvement.
• The threat to programming jobs is real, but the bigger risk is refusing to adapt rather than AI itself.
• Treating AI as a collaborative tool—rather than a replacement or a threat to resist—lets programmers amplify their own creativity and output.

The author shares their experience of creating Beep, a fictional programming language, in collaboration with the AI tool Claude Code. Through detailed examples, they explore features like lexical and dynamic scoping, as well as the AI's assistance in solving complex programming challenges and refactoring code.

• Claude Code built a working interpreter for "Beep," a made-up language with unusual scoping rules, largely autonomously from a spec.
• It handled the tricky distinction between lexical and dynamic scoping correctly, including edge cases the author hadn't fully worked out themselves.
• The AI could refactor and extend the codebase iteratively, adjusting to new requirements without breaking existing functionality.
• The author frames this as evidence that Claude Code is useful for genuine software design/problem-solving, not just boilerplate code generation.

The author explores the concept of "vibe coding," where non-coders use AI tools like Bolt to create applications with minimal technical knowledge. While the process seems accessible and fun, the resulting applications often lack depth and robustness, raising questions about their real-world effectiveness. The journey illustrates both the potential and limitations of such tools in empowering non-technical users.

• A non-coder used AI tool Bolt to build an app through "vibe coding" (describing what you want in plain language rather than writing code)
• The apps produced this way tend to look polished on the surface but lack real depth or robustness underneath
• The experiment highlights a gap between how accessible these AI tools feel and how functional/production-ready the output actually is

Durable Execution (DE) engines allow for the persistence of multi-step workflows, enabling them to resume from the last successful step after interruptions. This article explores the development of a simple DE engine called Persistasaurus in Java, which utilizes SQLite for logging execution state and highlights key implementation choices.

• Persistasaurus implements durable execution in Java by logging each step's execution state to SQLite, allowing workflows to resume from the last successful step after a crash.
• SQLite's single-file, embedded, transactional nature makes it a lightweight yet reliable choice for storing execution logs without needing a separate database server.
• The design records both function inputs/outputs and step completion status, so re-running a workflow skips already-completed steps and replays their cached results instead of re-executing side effects.
