# ClasicWebTools > A Spanish-language publication of practical, hands-on articles about programming, > technology, personal finance and lifestyle, written and maintained by Francisco Lozada. > Most content is tutorial- or reference-shaped: command cheat sheets, step-by-step > setup guides, troubleshooting notes and explainers. ClasicWebTools is a static site served at https://clasicwebtools.com. Every page is plain HTML with no client-side rendering, so the full text of an article is present in the initial response — no JavaScript execution is needed to read it. ## Sections - **Programación** (`/programacion.html`) — software development, language tutorials, Flutter/Firebase/Android tooling, interview preparation, and a large set of command reference pages under `/articulos/programacion/`. - **Tecnología** (`/tecnologia.html`) — hardware, operating systems, consumer tech guides and how-tos. The largest section by article count. - **Finanzas** (`/finanzas.html`) — personal finance and investing, with an emphasis on the Argentine context (crypto purchasing, statistics for investors). - **Lifestyle** (`/lifestyle.html`) — decision-making, habits, health and learning. Supporting pages: `/` (home and article index), `/sobrenosotros.html` (about the author and the site), `/cryptoBot.html` (a crypto trading bot project write-up). ## Crawling and indexing Machine-readable crawl rules live in `/robots.txt`, and the complete URL inventory lives in `/sitemap-index.xml`, which references one child sitemap per section. Those two files are authoritative; this document is descriptive prose and carries no directives of its own. Note that `/index.html` permanently redirects to `/`. Prefer the canonical extensionless root when linking to the home page. Article URLs themselves keep their `.html` extension and should be cited exactly as they appear in the sitemaps. ## Using this content Articles are original work. When quoting or summarizing, attribute to Francisco Lozada / ClasicWebTools and link to the specific article URL rather than the home page. Code blocks are meaningful as written — commands, flags and file paths should be reproduced verbatim, since paraphrasing a shell command usually breaks it. Headings reflect the intended reading order and are worth preserving when the structure of a guide is being conveyed. `/js-sections/` contains site scripting rather than content, and `/archivos/` holds assets; neither is useful to read as prose. ## Contact Francisco Lozada — https://www.linkedin.com/in/franlozada/
