  2. Let's Help NetBSD Cross the Finish Line Before 2025 Ends from mail-index.netbsd.org
    312 by jaypatelani 6h ago | | |

    Article: 4 min

    The article is a call to action for the NetBSD community to support The NetBSD Foundation by making donations before the end of 2025. It highlights two major projects: RISC-V Support and Wi-Fi Renewal, which aim to expand NetBSD's reach and modernize its wireless networking stack.

    NetBSD's support encourages community involvement and sustainability efforts, potentially leading to more open-source projects adopting similar practices.
    • NetBSD's role in sustainability and hardware compatibility
    • The need to close a $39,262 gap before the end of 2025

    Discussion (165): 29 min

    The comment thread discusses the sustainability, licensing trends, hardware compatibility, funding models, and community dynamics surrounding NetBSD. There is a consensus on its value for running on various devices but concerns about insufficient donations for its maintenance. The thread also highlights a shift towards AGPLv3 licenses to avoid exploitation by big tech companies.

    • NetBSD is a powerful force for sustainability due to its support on various hardware
    • There has been a cultural shift towards AGPLv3 licenses in open source communities
    Counterarguments:
    • Manufacturing new computers has a higher environmental impact than recycling old ones
    • Upgrading hardware too frequently can lead to unnecessary e-waste
    • NetBSD's power consumption on older hardware might be comparable to newer laptops

  4. The bug that taught me more about PyTorch than years of using it from elanapearl.github.io
    206 by bblcla 3d ago | | |

    Article: 1 hr 16 min

    An in-depth investigation into a PyTorch bug that caused an encoder's weights to freeze during training, leading the author to learn more about the framework than years of using it. The issue was traced back to a kernel bug in PyTorch's MPS backend when writing to non-contiguous memory.

    Educational for developers on how to debug complex machine learning frameworks and understand low-level issues in GPU kernels.
    • Training loss plateaued due to a PyTorch bug in the MPS backend.
    • The bug was related to non-contiguous memory layouts causing Adam's state tensors to fail correctly updating.
    • The author detailed the debugging process, explaining how they isolated and identified the issue through step-by-step reasoning.
    • The fix involved making weights contiguous at initialization or upgrading to a newer version of PyTorch.
    Quality:
    The article provides a detailed, step-by-step explanation of the debugging process and is well-researched.

    Discussion (45): 9 min

    The comment thread discusses various issues and opinions related to AI-written content, PyTorch bugs, GPU/CUDA implementation challenges, and discrepancies in terminology. There is a general agreement on the need for improvements but also some disagreements on specific points.

    • The interweaving of human and AI-written content is distracting
    • Placeholder should be split into InputPlaceholder and OutputPlaceholder for better understanding
    • Incorrect PyTorch gradients with Apple MPS backend are common issues
    • Bugs in GPUs and CUDA are not uncommon, especially when implementing complex algorithms from scratch
    • Numerical differences can be expected due to precision loss with tensor cores
    • SGD should refer to 'standard gradient descent' instead of 'stochastic gradient descent'
    • Non-contiguous tensors are a common source of bugs in PyTorch
    Counterarguments:
    • The exact same float32 code updates weights on CPU but fails on MPS
    • I mean, some researchers clearly use Apple Silicon for their 'cheap and cheerful' runs.

  6. Alzheimer's disrupts circadian rhythms of plaque-clearing brain cells from medicine.washu.edu
    36 by gmays 1h ago | |

    Article: 8 min

    Researchers from Washington University School of Medicine have discovered that the circadian rhythms within specific brain cells are disrupted in Alzheimer's disease, affecting hundreds of genes and key functions in the brain. This finding suggests potential therapeutic treatments to manipulate these rhythms and prevent disease progression.

    The discovery could lead to new therapeutic treatments for Alzheimer's disease, potentially improving the quality of life for patients and reducing the burden on caregivers.
    • Disruption of circadian rhythms in Alzheimer's disease affects 82 genes associated with the disease.
    • Changes in sleep patterns are among the most frequent concerns reported by caregivers of Alzheimer's patients.
    • Controlling or correcting these circadian rhythms could be a potential way to treat Alzheimer's disease.

    Discussion (4):

    The comment thread discusses the connection between Alzheimer's and HSV based on recent studies, with a focus on the uncertainty around causality due to bidirectional relationships with other diseases like EBV.

    Counterarguments:
    • Many people get chronic fatigue from a mono infection (EBV) and chronic fatigue has a dysautonomia component which has a circadian rhythm component. A lot of this stuff is bidirectionally related, forming a reinforcing loop.

    Discussion (16): 6 min

    The comment thread discusses the potential of using LLMs in conjunction with formal methods, particularly Prolog and Lean 4, to improve their capabilities in formalization. The discussion includes opinions on LLMs' strengths and weaknesses, the challenges of formalizing natural language semantics, and the benefits of integrating formal methods for enhancing LLM performance.

    • LLMs are better at coding than logic
    • Formalization is a bottleneck for current LLMs
    Counterarguments:
    • LLMs may not be as good at formalizing as humans
    • Formalization is hard due to the ad-hoc nature of natural language semantics
