  1. AVX2 is slower than SSE2-4.x under Windows ARM emulation from blogs.remobjects.com
    44 by vintagedave 1h ago | | |

    Article: 28 min

    The article discusses a study comparing the performance of AVX2 and SSE2-4.x instruction sets under Windows ARM emulation, concluding that AVX2 code runs at 2/3 the speed of equivalent SSE2-SSE4.x optimized code.

    Developers may need to adjust their strategies for targeting Windows ARM platforms, potentially leading to more optimized codebases.
    • Software developers should not compile for AVX2 if their app might run on Windows ARM, as performance is significantly impacted by emulation overhead.
    Quality:
    The article provides detailed information and analysis, avoiding sensationalism.

    Discussion (33): 4 min

    The comment thread discusses the necessity and impact of AVX2 vector instructions on CPU performance compared to ARM cores. Opinions vary regarding whether AVX2 should be banned due to its hardware requirements, while others argue that it provides significant benefits. The conversation also delves into ARM's lack of wider SIMD support, with discussions around software ecosystem challenges and the existence of SVE in ARM's Neoverse IP.

    • ARM cores lack wider SIMD support
    Counterarguments:
    • AVX2 has been common for a decade and provides net benefits.
    • AVX512 works well on Zen5 architecture.
    • AVX512 can be perceived differently if implemented initially with smaller register widths.
    • ARM cores have SVE support in their Neoverse IP, relevant in cloud applications.

  2. Terminals should generate the 256-color palette from gist.github.com
    328 by tosh 9h ago | | |

    Article: 12 min

    The article discusses the limitations of the 256-color palette in terminals and suggests an improvement by generating this palette from user's base16 theme, which would enhance color range while maintaining simplicity and compatibility.

    Enhancing the user experience by providing a more expressive color range in terminals without requiring additional configuration or complexity, potentially leading to increased adoption of custom themes and improved visual accessibility.
    • The 256-color palette is limited in range compared to truecolor but offers less overhead.
    • Base16 themes provide simplicity by defining colors in one place, but the default 256-color palette clashes with these themes and has poor readability.
    • Terminal programs could benefit from using this more expressive color range without added complexity or configuration files.

    Discussion (111): 23 min

    The discussion revolves around the limitations and improvements needed in color palettes for terminal emulators, with opinions divided on whether to implement truecolor support or maintain the fixed 16-255 range. Users express concerns about readability issues caused by developers' custom color choices, while others argue for consistency across different platforms.

    • The current color palette in terminal emulators is limiting and causes issues with custom themes.
    • Truecolor support should be implemented to provide better color control for developers and users.
    Counterarguments:
    • The fixed nature of the 16-255 color palette ensures consistency and reliability across different terminal emulators.
    • Customization options should be provided for developers to allow them to create their own color schemes without impacting user preferences.

  3. Mark Zuckerberg Lied to Congress. We Can't Trust His Testimony from dispatch.techoversight.org
    187 by speckx 2h ago | | |

    Article: 20 min

    The article discusses Mark Zuckerberg's testimony in front of the Senate Judiciary Committee regarding Meta's alleged harmful practices, particularly focusing on social media addiction and its impact on young people. It highlights evidence that contradicts Zuckerberg's claims during the hearing, including failed safety measures for teens, lack of compensation for victims, and deliberate harm to minors.

    Meta's actions could lead to stricter regulations on social media platforms targeting minors, potentially forcing them to implement more stringent safety measures and compensation for victims of harm caused by their products.
    • Zuckerberg lied and deceived the Committee during his testimony in 2024.
    • Meta's post-hearing investment in teen safety features is considered a PR stunt.
    • Internal documents reveal that Meta knowingly allowed sex trafficking on its platform, had a high strike threshold for accounts known to engage in trafficking, and failed to protect minors from sexually explicit interactions.
    • Meta pursued aggressive 'growth' strategies targeting children aged 5-10, despite federal law requiring safeguards for users under 13.
    Quality:
    The article presents a detailed analysis of the testimony and evidence, providing a balanced view while highlighting controversial aspects.

    Discussion (104): 22 min

    The comment thread discusses the need for regulation of social media companies like Meta, particularly in relation to children's safety and the conflict between profit and human good. Opinions vary on the effectiveness of regulations and the role of legislation such as the Kids Online Safety Act. The conversation also touches on issues of wealth disparity and justice.

    • The Kids Online Safety Act should be passed to address Meta's behavior towards children
    Counterarguments:
    • Regulations have not been effective in the past and will likely not work now.
    • The current systems are failing, so replacing them with another system won't solve the problem.
