THE BROWSER IS THE SANDBOX

The browser has potential as a secure sandbox for agentic AI tools, which automate tasks and require access to a user's local files and network. It has mechanisms for filesystem isolation, controlled network access via CSP, and secure code execution using iframes and WebAssembly. A demo project is displayed in this article that shows these capabilities.

AI TRIBALISM

Discussions around LLMs have devolved into unproductive tribalism, fueled by early negative associations with tech "hucksters" and fears of job displacement. AI agents are already capable of efficient code generation, bug fixing, and addressing complex issues like security and performance. Engineers need to keep experimenting with AI to stay on top of new tooling.

150,000 LINES OF VIBE CODED ELIXIR: THE GOOD, THE BAD, AND THE UGLY

BoothIQ used AI to write all 150,000 lines of its Elixir codebase, finding the language's small, terse, and immutable nature great for AI generation. AI is great at generating code efficiently, especially when aided by Elixir-specific tools like Tidewave. However, it struggles with architectural decisions, often produces defensive code trained on imperative languages, and is ineffective at debugging complex Elixir concurrency and understanding isolated test environments.

SOME C HABITS I EMPLOY FOR THE MODERN DAY

Despite not writing C frequently, the author has developed a specific set of programming habits and styles for C projects due to the language's lack of standardization. They typically use C23, define custom fixed-length types like `u8` and `i32`, use a `length+data` struct for strings, and prefer C23's `bool` type.
