The content emphasizes the importance of proper database design in software projects to accurately represent the reality of the business context in which they operate. It explains that databases consist of propositions that affirm or deny something about reality and that designing a database requires encoding these propositions in a way that can be processed by a database management system (DBMS). Many software developers lack formal training in database design or formal logic, leading to ad-hoc methods that can result in update anomalies and data inconsistencies, which can be detrimental.

In his blog post dated May 18, 2025, John Nunley revisits the topic of asynchronous programming in Rust, focusing on two models: async/await and callback-based event loops, specifically using calloop as an example. Nunley acknowledges that he has previously overemphasized async/await as the only method for writing asynchronous code in Rust, while in fact, various callback-based strategies have existed even before async/await. He notes that these callback loops, like libuv (

A user created an MCP server to allow LLMs read-only access to their emails, aiming to find the name of Donovan’s son. They engaged in a chat with the AI, Gemini, discussing strategies to locate this information without initially using any tools. Gemini conducted several searches within the user's emails, including keywords like “from:Donovan son” and “from:Donovan baby,” which yielded mixed results, often about other relatives rather than Donovan’s son. Ultimately, after exploring various search terms

In 1862, a group of 40 Japanese travelers, including many samurai, visited Europe for the first time in 240 years as Japan began to open up after centuries of isolation. Their mission was to learn about Western societies and to mitigate the effects of foreign influence on Japan following the arrival of American warships in 1854. During their trip, they were amazed by new technologies of the industrial age, particularly the telegraph, which allowed rapid communication across continents. They also visited the

The article discusses ACID and BASE transactions in databases, starting with simple explanations before diving deeper and including code examples. ACID transactions refer to four key properties: - **Atomicity**: Transactions are all or nothing. - **Consistency**: Data must conform to application rules (though maintaining this is the application's responsibility, not the database's). - **Isolation**: Transactions can occur simultaneously without interference. - **Durability**: Once a transaction is committed, it stays in the database.

The writer reflects on the journey of their Software Engineering Handbook one year after its launch in May 2024, initially celebrated with a trip to Iceland after a two-year effort. They aimed to create a comprehensive guide for navigating the software engineering field, addressing everything from job offers to project management. Despite receiving positive feedback from some readers who found it valuable and insightful, the author acknowledges a reality check concerning the book's impact and reach. They identify two significant drawbacks regarding structural and naming choices that hindered its

Amber Williams shares her thoughts on the importance and challenges of personal knowledge management systems (PKMS), or "second brains," which serve as repositories for collecting meaningful insights and experiences. Drawing on historical figures like Thomas Jefferson and Marcus Aurelius, she emphasizes the value of documenting knowledge but also raises concerns about privacy, longevity, and the efficiency of existing note-taking systems. Williams highlights popular PKMS tools like Notion, Obsidian, Evernote, and Logseq, questioning their sustainability and user experience over

The author emphasizes the importance of feedback and takes it seriously. They embarked on a personal project to analyze the Voynich Manuscript using modern natural language processing (NLP) techniques, focusing on clustering, part-of-speech inference, and identifying patterns without delving into speculative translations. Although the manuscript remains undeciphered, their analysis suggests it exhibits characteristics of structured language. The project stands apart from traditional methods, which typically argue between statistical analysis and conjecture. The author's approach employs computational linguistics to

The author reflects on common misconceptions in gaming hardware, particularly the idea that the Neo Geo's use of sprites was unique. They note that other systems, like ADK, Epoch, and NEC, also utilized similar sprite-centric technologies. The discussion shifts to Taito's Kiki KaiKai, a Shinto-themed shoot 'em up, and its later rendition by Natsume as Pocky & Rocky. The author expresses a strong fondness for Pocky & Rocky with Becky, while acknowledging

Kamal has introduced a highly anticipated feature called maintenance mode, allowing applications to undergo updates and migrations within a designated downtime window. Application deployment is now categorized into two modes: live (default) and maintenance. During maintenance mode, the Kamal proxy will return a 503 status code to indicate temporary unavailability, displaying a default error page to users. Additionally, users can customize error pages by configuring the error_pages_path in their application settings, enabling them to modify various status pages beyond just the 503

Mastering a subject requires a strong knowledge base, typically achieved through extensive practice and exposure. For part-time learners, like those studying a language, achieving mastery can be challenging due to limited practice. Traditional learning methods, such as classroom instruction or occasional homework, often fail to build enduring knowledge, especially for fact-heavy subjects. Spaced repetition systems (SRS) offer a solution by using software to present flashcards that prompt users to recall information based on a graded system. This method allows learners to review

The content discusses the comparison between relational databases (RDBs) and document-oriented databases, focusing on the rationale behind choosing each type, along with example code. It outlines the fundamental characteristics: RDBs store data in structured tables with defined schemas and support powerful querying through SQL, while document stores save data in its native format, typically as JSON documents, identified by unique IDs and organized in collections. The author notes that both database types have evolved, with most document stores now supporting SQL and ACID
