Minimum Effective Dose: The Kaizen Approach to Life

Recovering from a root canal, the author explores the concept of the 'minimum effective dose' for exercise and learning. This leads to a reflection on the all-or-nothing approach and an embrace of Kaizen, the philosophy of continuous improvement. Even 8 minutes of reading a day accumulates significant knowledge; even a 5-minute daily sketch builds a meaningful visual record. The author argues that finding one's minimum effective dose for various activities allows for consistent progress and avoids burnout from overly ambitious goals.

Faster CI with Mill: Selective Testing Strategies

2024-12-30

Running all tests in large codebases is inefficient. This article explores three selective testing approaches: folder-based, dependency-based, and heuristic-based. Folder-based is simple but may miss errors; dependency-based is more thorough but can over-test; heuristic-based optimizes test selection with custom rules, balancing speed and thoroughness. The Mill build tool natively supports dependency-based selective testing, significantly improving CI efficiency. However, combining it with heuristic methods further optimizes the balance between speed and test coverage.

LoFi's Fight for Survival Against the AI Tide

LoFi hip hop, a genre that organically exploded online in the mid-2010s, is facing a battle for survival against the onslaught of AI-generated music and cheap royalty-free tracks. Initially, LoFi offered unprecedented opportunities for bedroom musicians and independent artists. However, its commercialization has led platforms like Spotify to replace real artists with AI-generated and royalty-free music, diluting the royalty pool. Yet, Los Angeles-based musician Wish on the Beat has carved a new path, transforming her LoFi beats into ambient tracks, demonstrating the enduring value of authentic artistry. This highlights the importance of supporting independent musicians and resisting the tide of low-quality AI-generated music to preserve the diversity of the music ecosystem.

Austin Rents Plummet: A Construction Boom's Unexpected Consequence

Austin rents have been falling for nearly two years, a stark contrast to the pandemic-era surge. A massive apartment building boom in the Austin-Round Rock area has flooded the market with tens of thousands of new units, creating a surplus that's driven down rental costs. While this offers some relief, housing affordability remains a significant challenge, with many renters still heavily burdened by housing expenses. The construction boom itself was fueled by a shift in political attitudes towards housing development, with city officials becoming more supportive of new projects.

Coal for Soil Remediation: A Game-Changer?

Coal for Soil Remediation: A Game-Changer?

This article explores soil degradation and its impact on food security and climate change. Traditional agricultural practices have led to severe soil erosion and degradation. The author introduces biochar, a soil amendment that improves soil fertility, increases crop yields, and enhances carbon sequestration. However, biochar is expensive. The article highlights a cheaper alternative: coal char, produced from pyrolyzed coal. Preliminary studies suggest that coal char offers similar soil improvement benefits to biochar at a fraction of the cost (less than one-tenth). This presents a potential game-changer for large-scale soil remediation, but further research is needed to assess its long-term impacts and environmental risks.

Big Tech Bypasses the Grid: A Fair Fight?

Facing soaring energy demands, tech giants are increasingly seeking direct power deals with power plants, bypassing the congested public grid. Amazon Web Services' (AWS) deal with the Susquehanna nuclear plant exemplifies this trend, prompting a regulatory pause by the Federal Energy Regulatory Commission (FERC). Concerns center around potential price hikes for other consumers and fairness. While plant operators argue this improves efficiency and lowers costs, critics fear exacerbating energy shortages and allowing Big Tech to free-ride on grid infrastructure. FERC's decision will set a precedent for future energy market dynamics.

FDA Approves Novel Analgesic, Challenging Opioid Dominance?

The FDA has approved Vertex Pharmaceuticals' Journavx, a new pain medication designed to eliminate the risks of addiction and overdose associated with opioids. Journavx works differently than opioids, blocking proteins that trigger pain signals before they reach the brain. Trials showed it was more effective than a placebo, but not significantly better than a common opioid-acetaminophen combination. Despite its high cost ($15.50 per pill), its non-opioid mechanism and potential offer a significant step in combating the opioid crisis. However, disappointing results in later-stage trials for chronic pain cast uncertainty on its future.

Black Magic: A Blazing Fast Circular Buffer

2025-01-11

This article presents a clever optimization of circular buffers using virtual memory paging. Traditional circular buffer read/write operations are inefficient due to boundary handling. The author uses the `mmap` system call to map the buffer to two contiguous virtual memory regions. This allows writes to proceed continuously without boundary checks, drastically improving performance. This method leverages the OS to handle wrap-around automatically, eliminating complex boundary checks and modulo operations. The result is a threefold performance increase.

Wright's Paradox: Organic Architecture vs. Mile-High Skyscraper

The architectural world is divided on the issue of density: pro-density advocates for dense, centralized cities, while anti-density champions decentralized, sprawling suburbs. Frank Lloyd Wright, a renowned architect known for his organic approach emphasizing a building's connection to its surroundings, belonged to the latter camp. His Broadacre City exemplifies this philosophy. Ironically, Wright also designed a mile-high skyscraper, 'The Illinois,' a stark contrast to his organic principles, prompting reflection on the compatibility of organic architecture and high-rise buildings.
