Marco Cantu has finished annotating the "Mastering Delphi 5" book, making it available as a free PDF download. This updated edition provides modern context and corrections to the 20-year-old text, focusing on the core Delphi language and VCL framework concepts that remain relevant today. While acknowledging some outdated aspects, the annotations aim to clarify the book's content for a contemporary audience and highlight its enduring value for learning fundamental Delphi programming principles. Cantu sees this project as a stepping stone towards similarly updating his "Mastering Delphi 7" book.
Marco Cantu's blog post celebrates Delphi's 30th anniversary, reflecting on its enduring relevance in the software development world. He highlights Delphi's initial groundbreaking impact with its rapid application development (RAD) approach and visual component library, emphasizing its evolution over three decades to encompass cross-platform development, mobile, and now, even web and Linux. Cantu acknowledges challenges and missteps along the way but underscores Delphi's resilience and continued commitment to providing developers with robust and productive tools. He concludes by looking forward to the future of Delphi, anticipating further innovations and its ongoing contribution to the software landscape.
