  4. Why is the first C++ (m)allocation always 72 KB? from joelsiks.com
    28 by joelsiks 1h ago | |

    Article: 17 min

    The article explains why the first C++ (m)allocation is always 72 KB, which is due to exception handling infrastructure initialization in libstdc++. This allocation serves as an emergency pool for allocating memory for exceptions when malloc might fail. The article also discusses how this behavior can lead to confusion with tools like Valgrind and how newer versions of Valgrind now explicitly free the emergency pool.

    This knowledge helps developers understand the underlying mechanisms of memory allocation in C++, which can lead to more efficient and reliable code, potentially reducing bugs related to memory management.
    • Valgrind can misinterpret this allocation, leading to confusion about memory leaks.
    Quality:
    The article provides detailed technical information and explanations without bias or personal opinions.

    Discussion (277): 1 hr 1 min

    The comment thread discusses the controversy surrounding Anthropic and OpenAI, focusing on their differing stances on red lines in contracts with the US government. The main points of contention include Anthropic's more stringent restrictions compared to OpenAI's reliance on existing law for 'lawful use', concerns about political donations influencing AI development, and the implications of these decisions on AI ethics and safety.

    • OpenAI has a history of donating to political figures, which raises concerns about their ethics and trustworthiness
    Counterarguments:
    • OpenAI claims they have the same red lines as Anthropic, but based on government interpretation of legality.
