    18 by ingve 32m ago | |

    Article: 3 min

    The article discusses how rising DRAM prices are affecting the market for high-end single-board computers (SBCs), particularly those with 4/8 GB of RAM or more, making them unaffordable for many hobbyists. The Raspberry Pi brand has announced price increases for its products, and the author predicts that unless the situation changes, the hobbyist SBC market may decline.

    • Price increases for Raspberry Pi and other SBCs due to DRAM cost hikes
    • Reduction in new board launches
    • Mini PCs becoming unaffordable for many hobbyists
    • Impact on project design choices
    Quality:
    The article provides factual information and predictions based on current market conditions, without expressing strong personal opinions.

  2. Signing data structures the wrong way from blog.foks.pub
    51 by malgorithms 2h ago | | |

    Article: 16 min

    The article discusses the issue of domain separation in cryptographic data structures, which can lead to security vulnerabilities when signing, encrypting, MAC'ing, hashing, or authenticating different types of messages with similar encodings. It introduces FOKS (Fast Object Keyed Signatures) and Snowpack as solutions that use random, immutable 64-bit domain separators in the IDL (Interface Definition Language) to ensure that both signer and verifier agree on the data type being dealt with, preventing substitution attacks.

    Enhances security in cryptographic systems, potentially reducing the risk of substitution attacks and improving trust in digital communications.
    • Existing ad-hoc mitigations for domain separation bugs are insufficient.
    • Snowpack is an open-source serialization scheme that adopts FOKS's core idea, targeting Go and TypeScript with plans for more languages.

    Discussion (29): 6 min

    The comment thread discusses various approaches to domain separation in cryptographic protocols and the implementation of multiset hashing. Opinions vary on the efficiency and correctness of different methods, with some agreeing that an ad-hoc implementation can lead to errors and others emphasizing the importance of following established cryptographic principles.

    • Domain separators in IDL vs. in-band
    • Multiset hashing solution
    • Protobuf message option implementation
    • Incorrect design proposal
    Counterarguments:
    • Canonicalization takes O(nlogn) time and multiset hashing provides a solution to avoid this issue without a distinct canonicalization step.
    • Adding a message option in protobuf can solve the domain separation problem.
    • The article proposes an incorrect design that will result in bad things if implemented incorrectly.

  5. The revenge of the data scientist from hamel.dev
    47 by hamelsmu 4d ago | |

    Article: 16 min

    The article discusses the evolving role of data scientists in the context of advancements in AI and machine learning, particularly focusing on the shift from building predictive models to setting up experiments for model generalization, debugging stochastic systems, and designing metrics. It argues that while the job title might change, the core skills and responsibilities remain relevant.

    Data science fundamentals remain crucial for ensuring reliable and ethical AI systems; however, the shift towards automation might lead to a redefinition of roles within the industry.
    • Data scientists traditionally excel at statistics and software engineering, creating a high barrier to entry.
    • The heyday of the data scientist role might be over as AI advancements allow teams to integrate AI independently without needing data scientists for shipping AI products.
    • Training models is not the primary responsibility; setting up experiments, debugging stochastic systems, and designing metrics are crucial tasks.
    • Data science fundamentals such as exploratory data analysis, model evaluation, experimental design, data collection, and production ML remain essential.
    Quality:
    The article provides a balanced view on the evolving role of data scientists in AI/ML, highlighting both the challenges and opportunities.

    Discussion (5):

    The comment thread discusses the use of context data in AI development, focusing on LLMs' in-context learning capabilities and challenges such as test case creation, local minima issues, and the importance of confirming data accuracy. It also touches upon the difficulty level between writing test cases versus code and the limitations of LLMs.

    • The context data should be used for training and testing agents.
    • LLMs can perform in-context learning.
    • pg_textsearch is a good case for this development style.
    • Writing test cases is as hard as writing code.
    • LLMs may get trapped in local minima.
    • Data confirmation is crucial in AI projects.
