The article discusses some lesser-known quirks of JavaScript that can lead to confusion and unexpected behavior, particularly in relation to scope and function calls. While many programmers criticize JavaScript for issues like loose equality (e.g., '0' == 0), the author emphasizes that modern toolchains, such as linters, help mitigate such problems. However, more complex issues lurk beneath the surface, especially concerning how JavaScript handles variable scope and function calls, particularly with the `eval` function.

Rust is celebrating its 10th anniversary and is launching an initiative to create a Rust Vision RFC, aimed at reviewing its current state and future direction. The RFC will assess Rust's success in empowering users to build reliable software and identify areas for improvement. Rather than detailing specific designs or features, the RFC will provide higher-level recommendations and understand users' needs across various domains. To gather data for this effort, a survey is being conducted to connect with a broad range of stakeholders. The goal is to produce

The article discusses the existence of a universal open-source RAW format, DNG (Digital Negative), which was introduced by Adobe in 2004 to promote easier compatibility across different camera systems. Despite its availability, only a few camera manufacturers have adopted DNG, with most continuing to use their proprietary formats like Canon's CR3, Nikon's NEF, and Sony's ARW. This reliance on proprietary formats leads to compatibility issues for photo editing software, which must adapt to each file type. While some

The use of LIMIT and OFFSET pagination in SQL can lead to performance issues when OFFSET values are high, as the database must scan through all preceding records before returning results. This method is often employed as a temporary fix for slow queries, especially when large data sets are involved, but it becomes inefficient as OFFSET increases. To address these performance problems, the postgresql_cursor gem can be used, which leverages PostgreSQL cursors to iterate through query results without loading all data at once. This gem allows for
