  1. What an unprocessed photo looks like from maurycyz.com
    1725 by zdw 14h ago | | |

    Article: 6 min

    The article explains how a camera sensor captures raw data from an image, detailing the process from ADC values to final color representation and discusses the challenges in accurately representing human perception through digital images.

    • Raw sensor data is initially monochromatic
    • The process of color representation involves demosaicing
    • Non-linear curve application for brightness enhancement
    • White balance adjustment to correct color cast

    Discussion (285): 55 min

    The comment thread delves into the technical aspects and philosophical implications of digital photography, focusing on image processing techniques, sensor technology, and the authenticity of digitally manipulated images. Participants discuss Bayer filters, color theory, and the role of editing software in enhancing or altering photographs, while also engaging in debates about the definition of 'unprocessed' data and the extent to which image editing can be considered as 'faking' reality.

    • Modern photography is essentially signal processing with advanced algorithms and techniques.
    Counterarguments:
    • Some argue that the term 'unprocessed' is misleading when applied to raw camera data.
    • Others question whether certain image processing steps can be considered as 'faking' reality.

    Article: 9 min

    Z80-μLM is a conversational AI designed to run on a Z80 processor with 40KB of memory, featuring quantization-aware training (QAT) for efficient execution. It generates short character-by-character sequences and includes examples like 'tinychat' and 'guess', which demonstrate its capabilities in responding to casual questions and playing games.

    This project showcases the feasibility of running AI on resource-constrained hardware, potentially inspiring new applications in embedded systems and retro computing.

  7. You can make up HTML tags from maurycyz.com
    321 by todsacerdoti 10h ago | | |

    Article: 2 min

    The article discusses the ability to create custom HTML tags, explaining how browsers handle unrecognized tags and providing examples of when it might be beneficial to use custom tags for better readability. It also mentions the standardization of this behavior and the advantage of using descriptive tag names.

    Custom HTML tags can improve code readability and maintainability, potentially leading to more efficient development processes.
    • Creating custom HTML tags is possible and standardized behavior.
    • Unrecognized tags are treated as generic elements with effects defined by CSS.
    • Using hyphens in tag names ensures uniqueness across future HTML versions.
    • Custom tags offer better readability compared to using class names for nested structures.

    Discussion (120): 26 min

    The comment thread discusses the use and benefits of custom HTML elements, their impact on web development practices, and debates around semantic vs functional usage. It also touches upon trends in web component development and accessibility considerations.

    • Custom HTML elements provide dynamic behavior to unknown tags.
    • HTML is simpler than it seems, with many elements having equivalent functionality.
    Counterarguments:
    • Custom HTML elements can create confusion around semantic meaning in comparison to native tags.

  8. Huge Binaries from fzakaria.com
    86 by todsacerdoti 7h ago | | |

    Article: 17 min

    The article discusses the issue of large binary sizes, particularly those beyond 2GiB, which are common in mega-codebases due to static linking for speed and deployment simplicity. It explains how position-independent code is put together using relocation techniques and the limitations this poses on call instruction offsets.

    The article highlights the technical challenges and considerations in managing large codebases, which can affect software performance, deployment processes, and resource management within industries.
    • The 2GiB 'Relocation Barrier' limits the reach of call instructions.
    • Position-independent code uses relocation techniques to fixup code during final stages.

    Discussion (28): 3 min

    The comment thread discusses various opinions and technical insights on large binary sizes, particularly in relation to debug symbols. Topics include the size of C++ projects, dynamic linking challenges, alternative solutions like detached debug files, and the trade-offs between binary size and performance optimization.

    • Debug symbols are large due to detailed type information and other data in C++ projects.
    • Dynamic linking of C++ libraries is problematic.
    • Shipping debug symbols as separate files could reduce binary size.
    Counterarguments:
    • To be fair, they worked at Google, their engineering decisions are not normal. They might just decide that 25 GiB binaries are worth a 0.25% speedup at start time, potentially resulting in tens of millions of dollars' worth of difference.
    • I had observed binaries beyond 25GiB, including debug symbols. How is this possible? These companies prefer to statically build their services to speed up startup and simplify deployment.
