EHT Reveals Turbulent Accretion Flow Around M87*'s Black Hole

2025-01-25

The Event Horizon Telescope (EHT) Collaboration has released a new analysis of the supermassive black hole at the center of Messier 87 (M87*), combining observations from 2017 and 2018. The study confirms that M87*'s black hole rotational axis points away from Earth and highlights the significant role of turbulence within the accretion disk in explaining the observed shift in the ring's brightness peak. Using a vastly expanded simulation image library, the team confirmed the counter-clockwise 30-degree shift of the brightest region of the ring between 2017 and 2018. This research represents a major step forward in understanding the complex dynamics of black hole environments.

The Tyranny of Structurelessness: Power Dynamics in the Women's Liberation Movement

2025-01-22

This article examines the pitfalls of 'structureless' organizational forms in the women's liberation movement. Jo Freeman argues that seemingly structureless groups inevitably develop informal power structures, leading to elitism and exclusion. The lack of formal structures results in opaque decision-making processes, with power concentrated in the hands of a few, leaving the majority confused. The author advocates for formal, democratic organizational structures to ensure equitable power distribution and accountability, proposing principles for democratic structuring such as delegation of authority, responsibility, distributed power, and information sharing to foster the healthy development of the women's liberation movement.

JWST Detects Potentially Biosignature Gases on Exoplanet K2-18b

Using the James Webb Space Telescope, scientists have detected signs of dimethyl sulfide and dimethyl disulfide in the atmosphere of exoplanet K2-18b, chemicals produced by marine life on Earth. While not definitive proof of life, researchers call it the most promising sign yet of life beyond our solar system. K2-18b resides in the habitable zone, possessing the potential for liquid water, making life a possibility. This builds upon prior research identifying methane and carbon dioxide in K2-18b's atmosphere. Although alternative explanations exist, researchers are excited about the discovery and plan further investigation to confirm their findings.

Trump Halts TikTok Ban for 75 Days: A High-Stakes Gamble

President Trump issued an executive order temporarily halting enforcement of the TikTok ban for 75 days. This move aims to prevent penalties against American companies like Apple and Google for working with TikTok, but its legal standing is questionable. The ban stemmed from a law demanding TikTok divest from its Chinese parent company, ByteDance, and Trump's action effectively circumvents this legislation. While the reprieve may offer temporary relief, the decision carries significant legal and political risks, with massive fines still a possibility and its effectiveness highly debated.

After a year of using bcachefs, Steinar Gunderson has migrated to XFS. His reason? A lack of confidence in bcachefs' future. While appreciating its compression and mixed SSD/HDD capabilities, he found the developer's uncompromising attitude, hostility towards distributions like Debian, and numerous unfixed bugs (including catastrophic data loss) unbearable. Reporting bugs proved a frustrating experience, with the developer prioritizing arguments with Debian over bug fixes. He ultimately chose the stability of XFS, sacrificing compression benefits, a trade-off he deems worthwhile.

Code Colocation: The Secret to Maintainable Codebases

2025-02-19

This article champions code colocation as a key to maintainable software. The author argues that keeping code comments, templates, CSS, unit tests, and application state close to their related code significantly improves maintainability, applicability, and ease of use. Compared to scattering these elements across various directories, colocation avoids synchronization issues, makes finding things easier, reduces context switching, and thus lessens technical debt. Examples from modern frameworks like React, Vue, and Angular illustrate the practice, highlighting how colocation boosts readability and simplifies codebase management. The article also addresses strategies for utility functions and resource files, recommending placing them as close as possible to their usage to minimize maintenance overhead and cognitive load.

The Death of Authenticity: How 'Authenticity' Became a Commodity

The Death of Authenticity: How 'Authenticity' Became a Commodity

This essay traces the evolution of 'authenticity' in contemporary culture. From the early hipster obsession with independent, non-commodified goods to the current prevalence of marketing terms like 'handmade' and 'small-batch,' authenticity has shifted from a scarce commodity to a ubiquitous one. The author argues that the rise of the internet and social media has lowered the cost of information dissemination, leading to shared value replacing scarcity and ushering in a 'post-authenticity' era. Brands are no longer simply commodities but active participants in shaping culture, demanding a more nuanced approach to critique.

Intensional Programming in Joy: Introspection with a Single Operator

2025-02-12

This article explores intensional programming in Joy, a stack-based functional programming language. Joy itself is extensional, lacking the ability to 'dissect' code blocks. The author proposes two intensional operators: 'map' and 'quota', proving their mutual expressibility. While behaviorally equivalent, intensional programs can distinguish a single operator from a subprogram with multiple commands. This opens avenues for exploring weaker notions of equivalence in intensional languages and demonstrates a robust approach to introducing intensionality in minimalist languages like Joy.

Jupyter Notebooks and LLMs: An Unexpected Cost Optimization

2025-01-21

The author used LLMs for coding assistance, initially with a ContinueDev + OpenRouter setup. Costs unexpectedly soared. Investigation revealed that Jupyter Notebook (.ipynb) files contain significant hidden content (code outputs, metadata, base64-encoded images), leading to a large token count and increased LLM call costs. The solution was converting .ipynb files to .py files and removing base64-encoded images. This reduced costs by 94% and latency as well. The post highlights the importance of mindful input when using LLMs and recommends regularly checking costs.

Researchers at UCSF are using AI and cutting-edge neuroimaging technologies to build a 'silicon brain' that mimics human brain activity. By integrating data from various brain scanning techniques (like fMRI and neuropixel probes), along with text, speech, and behavioral data, they're creating an artificial neural network that replicates human brain activity patterns. This research promises to revolutionize brain-computer interfaces, enabling devices that restore speech or movement without extensive calibration and opening new avenues for diagnosing and treating neuropsychiatric disorders. Ethical considerations, such as data privacy and potential misuse, are also being addressed.
