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.

Drupal, Development Technical Notes Update

This serves as a compilation of recent blog updates focused on Drupal development within an Ubuntu Linux environment, primarily intended for personal tech note consolidation. The listed entries cover a range of topics including general Drupal 8 development in PHP, an early look at a contributed Google Books module for Drupal 8, quick setup notes for Drupal web development on Ubuntu 16.04, technical configurations for Drupal 7, and tutorials specifically addressing Drupal 8 migration processes. These entries represent key technical notes from the past year, with a significant portion dedicated to Drupal, though other technology-related notes, including a larger collection currently residing on Tumblr, will be integrated at a later time for a more comprehensive overview.

• Drupal 8 Development in PHP
• Drupal 8 Alpha Contributed Module: Google Books
• Ubuntu 16.04 Drupal Web Dev Quick Setup Notes
• Drupal 7 Configuration Technical-Notes
• Drupal 8 Migration Tutorials

Semantic Scholar New Site

I recently came across a new website called Semantic Scholar, and I've been exploring its collection of research papers and data. One thing that caught my eye was some interesting graphics illustrating the MASC, or Multiple Instruction Stream Associative Computer model. It seems like they have access to a lot of original research documents, because I even found a text comparing PRAM and MASC ( one on PRAM vs MASC ). I'm finding this site quite interesting and potentially useful for my own research.

Quick: Apache Spark a 'Fast' Post

Over at the other blog site made a 'quick' post about Apache Spark thinking that it is good that parallel computing is taking off as we have more and more data and cluster computing is commonplace now with AWS and Google-Cloud.
