Tech Notes : Drupal, Ubuntu, PHP, MySQL, WebDevelopment, Short-List

This collection of tech notes is a personal repository for quick reference across development and server administration. It currently includes insights on Drupal performance optimization via MySQL indexing and modules like NodeQueue, alongside practical guides for Linux image optimization and CSS workflow with SCSS, Sass, and Gulp. Notes also cover setting up Symfony, optimizing PHP, and Drupal caching with Varnish. Explorations into AR toolkits and Drupal's evolution (D8 to D9, Twig theming, Headless Drupal, permissions) are present, as are Symfony learning resources and Drupal performance modules like AdvAgg. Local development with Docker and Kalabox is documented, alongside PHP upgrades, HTML archiving, Drupal 8 API, data migration, and specific Drupal 7 features (block caching, CKEditor). Server topics include PHP version management, Varnish setup, Memcached, SSL, PHP OpCode cache, MySQL Workbench, and installation guides for various software on Linux. Even desktop customization and notes on a Drupal 8 Google Books module, Rspec, Shopify theming, Semantic Scholar, and Apache Spark are included, concluding with Drupal 8 performance testing. More Drupal 8 notes are expected, but this already offers a broad technical overview.
