Caveman Debugging in the Modern Age
Caveman debugging uses print statements to track code execution. Integrating it with IntelliJ IDEA's Live Template feature enhances productivity through custom templates, streamlining repetitive tasks and improving coding efficiency.
Read original article
Caveman debugging, or "printf debugging," is a fundamental method for debugging code that involves inserting print statements to monitor program execution and variable values. This technique, highlighted by Brian Kernighan in 1979, remains effective today. The article discusses the integration of caveman debugging with IntelliJ IDEA's Live Template feature, which allows users to insert predefined code snippets quickly. The author shares two custom live templates that enhance productivity: one for printing class and function names and another for measuring execution time. These templates streamline the debugging process, reducing the time spent on repetitive tasks. The author encourages readers to analyze their workflows to identify repetitive coding patterns and create custom live templates tailored to their needs. This approach can significantly improve long-term productivity in coding. The post concludes with an invitation for feedback and sharing of additional live templates.

Features I'd like to see in future IDEs
Proposed improvements for IDEs include queryable expressions for debugging, coloration of comments, embedding images, a personal code vault for snippets, and commit masks to prevent accidental code commits.
Profiling with Ctrl-C
Ctrl-C profiling is an effective method for identifying performance issues in programs, especially in challenging environments, despite its limitations in sampling frequency and multi-threaded contexts.
Profiling with Ctrl-C
Ctrl-C profiling is an effective method for identifying performance issues in programs, offering a simpler alternative to traditional profilers, especially in challenging environments and for less experienced users.

The article emphasizes interactive development in Clojure using REPL for efficient coding, structural editing for code boundaries, and tools like "snitch" and "clj-reload" to enhance debugging and workflow.
Kernighan's Lever (2012)
Kernighan's lever highlights that while clever coding can complicate debugging, facing challenges fosters skill development, making debugging a valuable learning opportunity that enhances programming capabilities.
4 commentsEver since, I redoubled my effort to use my brain for debugging, plus simple print statements and logging. Only when I am ready to jump out a window do I fire up a debugger.
(BTW, for three years I was in charge of the Borland Turbo Debugger test team.)
I am a huge fan of print debugging. Debuggers have their place, but most of the time print is just easier and it fits better into my mental model.
