Attention as Electromagnetic Field Line Management: A New Model of Consciousness

2024-12-17

Attention as Electromagnetic Field Line Management: A New Model of Consciousness

Qualia Research Institute proposes a novel model of attention, conceptualizing it as the management of dynamic patterns in the brain's electromagnetic field. By simulating electric field lines arising from weighted sums of harmonic oscillations, researchers demonstrate how attention controls charge density by modulating underlying resonant modes, explaining seemingly random fluctuations and drifts in attentional behavior. This model also offers a potential explanation for psychedelic experiences, suggesting that psychedelics disrupt the normal flow of attention by altering the configuration of harmonic modes. The research provides a new lens for understanding consciousness and developing novel neuro-interventions, such as inducing exotic states of consciousness by non-invasively perturbing the phase locking of attention.

From Voltaire's Garden to Cultivating a Life: A Writer's Journey Through Gardening and Prose

This essay explores the meaning of "cultivating one's own garden" through the author's personal experiences and literary references. Beginning with her first gardening attempt in England, the author connects Voltaire's Candide and the metaphor of tending a garden to her own journey as a writer. The fictional Mars potato garden in Andy Weir's *The Martian* further illuminates this theme, illustrating the process of finding purpose and meaning amidst life's challenges. Gardening becomes a metaphor for the writer's craft, requiring patience, perseverance, and attention to detail, ultimately yielding both fruitful results and inner fulfillment.

Systemd: Red Hat's Stealth Takeover of the Linux Ecosystem?

2025-01-20

This article delves into the true motivations behind systemd, revealing how Red Hat leveraged its business interests in embedded devices to transform systemd from a simple init system into a core component of the Linux operating system. The author alleges that Red Hat used various tactics, including lobbying open-source projects to depend on systemd and poaching developers from other distributions, to exert control over the Linux ecosystem, sparking a backlash within the open-source community and leading to the resignation of several Debian developers. Systemd is described as a monolithic system with privacy concerns, and Red Hat's ambition is portrayed as creating the next Windows. The article concludes by advocating a return to community-driven development and recommending alternatives to systemd, such as runit and s6.

Hertz Desperate to Offload Tesla Inventory, Offers Deep Discounts

Rental car giant Hertz is aggressively selling off its Tesla Model 3 inventory at drastically reduced prices. A Hertz customer posted on Reddit a screenshot showing a 2023 Model 3 with 30,000 miles for just $17,913 – significantly below market value. While buying used rental cars carries risks, the low price and remaining battery warranty are tempting many. Hertz's move is likely a response to high depreciation on its large Tesla fleet and a push to clear inventory before year-end.

GitHub's UI: Past, Present, and a 10x Frontend Cost

2025-01-24

This is a retrospective by GitHub engineer Joel Hawksley on the evolution of GitHub's UI architecture. He recounts GitHub's journey from simpler beginnings to its current focus on usability and accessibility, highlighting the challenges encountered along the way. He emphasizes that mobile is the new baseline, and building and maintaining design systems (like Primer) comes with unforeseen costs, with frontend code complexity being 10 times that of backend. Hawksley advises developers to avoid reinventing the wheel, leverage existing design systems, and carefully budget for frontend complexity to reduce costs and improve efficiency.

A New Twist: Molecular Machines Loop and Twist Chromosomes

A New Twist: Molecular Machines Loop and Twist Chromosomes

Scientists have discovered a new function of the molecular motors that shape our chromosomes: SMC proteins not only form long loops in DNA but also significantly twist the DNA during loop formation. Published in Science Advances, the research reveals that SMC proteins introduce a left-handed twist of 0.6 turns in each DNA loop extrusion step. This twisting action is conserved across species, observed in both human and yeast cells, highlighting its evolutionary importance. This finding enhances our understanding of chromosome structure and function and provides insights into developmental diseases like cohesinopathies.

Thread Safety Nightmare: A Mysterious Crash on ARM64, Even with Safe Rust

Thread Safety Nightmare: A Mysterious Crash on ARM64, Even with Safe Rust

While porting network I/O code from Python to Rust in EdgeDB, a mysterious crash on ARM64 platforms emerged. Initially suspected to be a deadlock, the root cause turned out to be thread-unsafe behavior in the `setenv` and `getenv` functions. On ARM64, the `openssl-probe` library uses `setenv` to set environment variables, while another thread concurrently calls `getenv`. This reallocates the `environ` array, leading to a crash. The solution involved switching reqwest's TLS backend from rust-native-tls to rustls. This highlights how even in memory-safe Rust, interactions with the C standard library can still introduce thread safety issues.

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.
