Airlines Secretly Charging Solo Travelers More

2025-05-29

Airlines Secretly Charging Solo Travelers More

A recent investigation revealed that the three largest US airlines (Delta, American, and United) are charging solo travelers higher fares than those booking for multiple passengers. Airlines adjust fare classes based on the number of passengers; solo travelers often only see higher-priced tickets, while group bookings unlock cheaper "deep discount" fares. This isn't universal, but it's confirmed and could significantly cost solo travelers more. Airlines have not commented, but the practice appears to be another method of segmenting customers to extract higher profits from business travelers.

Why are Thunderstorms Rare in the UK?

The author observes a stark difference in thunderstorm frequency between Spain and the UK. The article explains thunderstorm formation: warm, moist air rises, colliding with cooler air, creating convection. Water droplets freeze into ice crystals, leading to charge separation and ultimately, lightning and thunder. Lightning's color stems from incandescence at high temperatures and luminescence from excited nitrogen. The article concludes that thunderstorms require warm, humid conditions, which are less common in the UK's higher latitude and cooler climate.

PLAttice: A 3D-Printed, Assembled Lattice for Large Structures

2025-05-10

Zach Fredin developed PLAttice, an assembled lattice structure entirely 3D-printed from PLA. Composed of struts, nodes, and pins, PLAttice allows for the reversible construction of structures significantly larger than the printer bed. A successful test built a square box truss weighing approximately 800 g/m, capable of spanning up to 4 meters before buckling. While the PLA struts are the weakest link, the design offers a novel approach to building large structures; future iterations could utilize stronger materials for the struts. PLAttice includes additional components like feet for mounting and specialized tools for assembly and disassembly. Although assembly isn't effortless, PLAttice enables the creation of interesting and useful structures, such as a kitchen pendant lamp. The project's files are released under CC-BY-SA 4.0.

The Verbosity Problem: Why LLMs Generate Bloated Code

This article explores the issue of large language models (LLMs) generating overly verbose and inefficient code. The author argues that the token-based pricing model of many AI coding assistants incentivizes the generation of lengthy code, even if it's less efficient. This is because more tokens processed mean more revenue. The author outlines strategies to mitigate this, including forcing planning before coding, implementing strict permission protocols, using Git for experimentation and ruthless pruning, and utilizing cheaper models. The ultimate solution, the author proposes, is for AI companies to shift their economic incentives to prioritize code quality over token count.

The SaaS Pricing Revolution: From Per-Seat to Pay-as-You-Go, Driven by AI

The rise of AI, particularly computationally intensive reasoning models, is reshaping the SaaS business model. High AI inference costs are forcing SaaS companies to shift from traditional per-seat licensing to usage-based, pay-as-you-go pricing. This isn't just a pricing experiment; it's an economic necessity for some to manage the cost of running AI-powered services. Companies like Bolt.new have already adopted token-based pricing, aligning revenue with actual usage. Established players like ServiceNow are using hybrid models, combining base seat licenses with pay-per-use AI credits. This shift may lead to revenue volatility but better reflects product value and attracts investors. However, variable costs for customers and revenue fluctuations for providers are downsides. The future of this model depends on whether AI compute costs decrease.

The Paradox of Effort in AI Development

Using the childhood analogy of damming a creek, the author explores the tension between striving for maximum effort and making wise choices in AI development. Initially, like a child, the author tried building dams with small rocks and leaves, only to discover a more efficient method with a shovel. This realization highlights how 'victory' can sometimes mean a shrinking of the game's space. Similarly, in AI, the author relentlessly pursued an investment banking job, only to find, upon success, that the game of 'making as much money as possible' was no longer available. He argues that against overwhelming forces (nature, the market), full effort can be counterproductive. Anthropic's recent report on educational applications, however, suggests a growing awareness of potential risks, akin to noticing the struggling clams on a beach.

Tipping in America: A Complex Legacy

Tipping in American restaurants is commonplace, but its history is complex. Introduced from Europe, it was initially resisted as un-American and classist. However, after the abolition of slavery, it became a primary income source for many Black service workers and spread through the Pullman railway company. Despite attempts at legislative abolition, it became entrenched, evolving into the current system with a 'tip credit' against minimum wage, leaving many service workers earning significantly less than the minimum wage. Today, the tipping system faces pressure from customers, employees, and restaurant owners, with its future uncertain but reform increasingly demanded.
