    Discussion (130): 28 min

    The comment thread discusses the impact of AI-generated code (referred to as 'AI slop') on open-source projects, with suggestions for implementing reputation systems and trust mechanisms. There is debate about the effectiveness of these solutions, particularly in relation to past failures like the Web of Trust, and the potential use of blockchain technology.

    • LLMs are accelerating towards a Dune-like universe with AI before humans
    • Butlerian Jihad is necessary to progress
    • Open source devolving into a 'slop fest'
    • AI slop is a problem for maintainers
    Counterarguments:
    • AI slop is not a problem, it's just low-quality contributions
    • Web of Trust failed because it was too complex and wasteful
    • Blockchain technology may be too complex to implement reputation systems efficiently

  4. The Little Bool of Doom (2025) from blog.svgames.pl
    42 by pocksuppet 2h ago | | |

    Article: 29 min

    The article discusses a compilation error encountered while maintaining chocolate-doom, a DOOM-related package in Fedora Linux. The issue arises due to changes in GCC's default C standard from -std=gnu17 to -std=gnu23 during the Fedora Mass Rebuild process. This results in a conflict between the custom boolean type used by chocolate-doom and the new built-in bool type introduced with C23. Various solutions are explored, including explicitly setting the C standard, modifying the code to use the built-in bool type, or renaming enum variants. The article also delves into the behavior of the custom boolean type when compared to the _Bool type in assembly level instructions.

    This issue highlights the importance of understanding language standards and compiler behavior in software development, particularly when maintaining cross-platform projects or updating dependencies. It encourages developers to be aware of potential compatibility issues during major updates.
    • Exploration of solutions to fix compilation errors
    • Behavior analysis at assembly level
    Quality:
    The article provides detailed technical analysis and explanations, avoiding sensationalism.

    Discussion (10): 2 min

    The comment thread discusses the use of the Godbolt compiler explorer for debugging C/C++ code, with opinions on its effectiveness compared to reading assembly. It also touches on setting the C standard explicitly and compares it to Rust's approach.

    • The Godbolt compiler explorer can aid in debugging
    • Reading assembly code may not be efficient for all debugging tasks
    Counterarguments:
    • Debugging at a higher level (C language) may be more efficient than reading assembly
    • The solution of setting the C standard is practical but might not generalize to other problems
