Advertising: A Cancerous Metaphor

2025-02-10

This article draws a striking parallel between advertising and cancer, highlighting their shared characteristics: uncontrolled growth, destructive consequences, resilience, and resource consumption. It argues that advertising, far from simply informing consumers, has become manipulative and deceptive, consuming vast corporate resources, polluting media channels, distorting decision-making, and eroding trust. Even in saturated markets, advertising competition becomes a zero-sum game, forcing companies into a vicious cycle of escalating spending. The author uses a powerful metaphor to expose the negative impacts and potential harms of advertising.

Genius and Folly: F. Scott Fitzgerald and The Great Gatsby

This essay explores Erasmus's praise of folly in *The Praise of Folly* and connects it to F. Scott Fitzgerald and his work, *The Great Gatsby*. Erasmus argues that folly isn't worthless; it fosters art and love, while wisdom isn't always noble. Fitzgerald's life was full of successes and failures, brilliance and ruin. He squandered his talent on fleeting fame and superficiality, ultimately unable to escape folly's grasp. Gatsby embodies this folly, chasing dreams while lost in illusory prosperity and romance. The essay argues that Fitzgerald wasn't lacking wisdom, but rather intertwined folly and wisdom to create uniquely compelling literature.

When a Simple Concurrent Program Defies Intuition

2025-01-18

A seemingly simple concurrent program, involving two processes incrementing a variable 'n' ten times each, yielded a surprising result when analyzed with a model checker. Intuitively, the final value of 'n' should be between 10 and 20. However, an extreme interleaving of the processes resulted in 'n' being 2. While a Go program attempting to reproduce this behavior failed, highlighting the rarity of such extreme interleavings in practice, the example underscores the complexities and counter-intuitive nature of concurrent programming.

7 Lessons from Building a Small-Scale AI Application

This article details seven lessons learned from building a small-scale AI assistant over the past year. The author discovered that scalability issues arose earlier than anticipated. AI programming is stochastic, requiring iterative adjustments to prompts, fine-tuning, preference tuning, and hyperparameters. Data quality is crucial, with significant time investment in building and maintaining a high-quality dataset and processing pipeline. Model evaluation is equally important, as simple validation sets often fail to capture real-world edge cases. Trust and quality are paramount, demanding continuous experimentation and evaluation. The training pipeline itself is the core intellectual property, constantly refined through iteration. Finally, the author cautions against over-reliance on AI libraries due to potential incompleteness or poor ecosystem integration; building directly upon lower-level abstractions is often more reliable.

Service as a Software Substitute (SaaSS): Another Threat to Your Computing Freedom

2025-02-06

This article explores the concept of "Service as a Software Substitute (SaaSS)", which refers to using someone else's service as a replacement for running your own program. Richard Stallman argues that SaaSS deprives users of control over their computing because the process is handed over to servers controlled by others. This is similar to proprietary software, both presenting security risks such as data leaks and backdoors. The author calls for users to reject SaaSS and choose to use free software and programs running on computers they control to maintain their computing freedom.

The Limits of Scaling in AI: Is Brute Force Reaching Its End?

A survey of 475 AI researchers reveals that simply scaling up current AI approaches is unlikely to lead to Artificial General Intelligence (AGI). Despite massive investments in data centers by tech giants, diminishing returns are evident. OpenAI's latest GPT model shows limited improvement, while DeepSeek demonstrates comparable AI performance at a fraction of the cost and energy consumption. This suggests that cheaper, more efficient methods, such as OpenAI's test-time compute and DeepSeek's 'mixture of experts' approach, are the future. However, large companies continue to favor brute-force scaling, leaving smaller startups to explore more economical alternatives.
