Removed numerous local image and document files from content posts and updated markdown files to reference external image and document URLs instead. This reduces repository size and centralizes media hosting, improving maintainability.

Added summaries of Kent Beck's analysis on programming deflation and Sean Goedecke's article on technical taste in software engineering. Expanded the tags to include relevant authors and topics. These additions provide readers with insights into the evolving cost of software development and the importance of flexible engineering values.

Added the content and image for Newsletter #59, covering topics such as compression algorithms, AI-assisted coding, branchless programming, long-running AI coding assistants, and insights on experience in software development.

Added the content for Newsletter #58 in Vietnamese, covering topics such as productive decision-making for engineers, event-driven systems, developer culture, AI tool calls, logging secrets, and more. Included several illustrative images from ByteByteGo to accompany the post.
