The discussion revolves around coding guidelines in the Curl project, especially regarding the use of C programming language. Key points include concerns about naming conventions, function lengths, line widths, and overall code readability. Many commenters highlight the tension between traditional C practices (like short identifiers) and the modern shift towards more descriptive coding standards. There's a critical evaluation of the idea that code should be concise and narrow, and participants express their experiences with both successful and challenging aspects of Curl's contributions and testing framework. Additionally, vulnerabilities linked to C are identified, yet some affirm that similar issues could arise in other languages. Overall, the discussion emphasizes the importance of readability and common sense in coding practices and raises questions on how to balance tradition with current standards.
