In spring 2003, attorney Tim Searchinger experienced a sense of unease while reading a complex paper from Argonne National Laboratory about the greenhouse gas emissions of using corn ethanol instead of gasoline. Despite lacking formal scientific credentials, Searchinger's skepticism led him to question the paper's conclusions. He was primarily focused on wetlands conservation but had an agriculture background, prompting his interest in the environmental impact of farming practices. His instinctive doubts about the study ultimately set him on a new path, influencing the discourse

Mark Weiser’s 1992 talk critiques the metaphor of "copilot" as a representation of AI, arguing against the notion of AI agents that interact directly with users. He contrasts this with the idea of creating systems that seamlessly integrate with human abilities, advocating for an “invisible computer” that enhances human awareness without demanding attention. Weiser’s vision is illustrated through the use of a Head-Up Display (HUD) in airplanes, which provides critical information without interrupting the pilot’s focus. He

The content emphasizes the idea of intentionally configuring Postgres to perform slowly, contrary to the typical goal of optimizing for speed. The author, while considering a unique approach to Postgres tuning, aims to create a configuration that processes queries as slowly as possible, though still allowing at least one transaction to complete in a reasonable timeframe. This challenge involves adjusting parameters in the postgresql.conf file without resorting to extreme measures like severely throttling CPU or removing indexes. To assess the performance, the author plans to

The content discusses a question from Mika Moilanen regarding the differences between using an abstract class and a delegate object for sharing common functionality. It emphasizes a more flexible and healthy way to evaluate these choices, as opposed to rigid rules like "always choose X" or "never do Y." The author hints at a future discussion on a topic referred to as "mechanics-ism," expressing the need to gather their thoughts more clearly before doing so. The list mentioned is not exhaustive but aims to illustrate the

The analysis focuses on performance and privacy issues in Trae IDE, a fork of Visual Studio Code by ByteDance. Key findings indicate that Trae consumes significantly more resources, using 3.7 times more processes and 6.3 times more memory than VSCode. Despite reporting these issues to Trae's developers, who acknowledged them and addressed some in version 2.0.2, Trae still exhibits high resource usage, potentially due to poor optimization or memory leaks. Network monitoring revealed ongoing

Python 3.4 introduced the asyncio library, which was solidified in Python 3.5 with the addition of the async and await keywords for asynchronous programming. However, asyncio has been criticized for its complexity and design flaws, making it difficult to use. Other languages and libraries like Kotlin and Swift have implemented asynchronous programming more effectively, raising questions about how asyncio achieved its non-provisional status despite its issues. The Trio library and AnyIO library offer alternatives that address many of asyncio's shortcomings while maintaining
