Love: The Foundation of Morality? Iris Murdoch's Perspective

Philosopher Iris Murdoch argues that love is central to morality. She posits that morality hinges on how we perceive the world, and that 'attentive love' helps overcome self-centered biases, allowing for clearer understanding of others and more ethical actions. Murdoch uses the example of a mother-in-law's prejudiced view of her daughter-in-law to illustrate that even without outward actions, biased perceptions constitute a moral failing. Overcoming this requires attentive love, which redirects us from self-focus towards others, leading to a truer grasp of reality.

Why LLMs Fail at Creativity: The Surprise Problem

Large Language Models (LLMs) struggle with comedy, art, journalism, research, and science because they're fundamentally designed to avoid surprises. The author argues that humor, good stories, and impactful research all hinge on surprising elements that are ultimately inevitable in hindsight. LLMs, trained to predict the next word, minimize surprise, resulting in predictable and uninspired output. Improving LLMs requires a shift towards a curiosity-driven architecture that actively seeks out and interprets surprising truths, rather than simply avoiding them.

16 Billion Passwords Exposed? Not Quite.

A recent headline claiming 16 billion passwords were exposed in a record-breaking breach sparked widespread concern. Security expert Troy Hunt investigated and found the reality far less alarming. The data wasn't from a single breach, but aggregated from multiple infostealer datasets. Significant duplication existed, with most email/password combinations already in the Have I Been Pwned (HIBP) database. Only 4.4 million unique email addresses were newly added. The sensationalized headline misrepresented the situation, highlighting the need for a more nuanced understanding of data breaches.

Uranus: Not as Cold and Dead as We Thought

A new study reveals Uranus possesses internal heat, contradicting previous observations. Researchers found Uranus radiates more heat than it receives from the sun, indicating a slow release of residual heat from its formation. This discovery enhances our understanding of Uranus's origin and evolution, informing future exploration missions and potentially providing insights into Earth's climate and atmospheric processes. While Uranus's internal heat is weaker than other gas giants, its energy levels fluctuate with its lengthy 20-year seasons, likely due to its eccentric orbit and tilted spin. This research significantly supports NASA's planned Uranus mission and offers novel approaches to studying radiant energy in other planets, both within and beyond our solar system.

Small is the New Big: Building for One in the Age of AI

In the era of AI-assisted coding, the cost of building small, personal applications has plummeted. The author shares anecdotes of creating several small utilities: a private Slack workspace for a hundred people, a simple app for sending postcards to his mother, and a small program that calls her to remind her to take medication. These aren't designed for scale, but to meet specific needs for himself and a small circle. The author argues that the real luxury isn't speed or cost, but the freedom to stop, to build something small, useful, and perfectly personal, without the obligation to grow it until it breaks. In a world obsessed with scale, there's quiet satisfaction in leaving 'good enough' alone.

Itch.io's Payment Processing Predicament: Is Building Your Own System the Answer?

2025-08-16

Itch.io faced backlash after payment processors forced them to remove adult content. Many suggested Itch.io create its own payment system or use one that handles adult material. A seasoned SRE with a background in finance and tech debunks these easy solutions. The article details the immense challenges of building a payment processor: bank sponsorship, licensing, KYC/KYCC compliance, and substantial security and compliance costs. Even finding an adult-content-friendly processor (like CCBill) comes with exorbitant fees and risks. The core issue, however, is that any part of the payment chain can be influenced by political pressure or moral censorship. Switching processors won't solve Itch.io's fundamental problem.
