This guide provides a compendium of Selenium WebDriver resources to help beginners or advanced users learn about the Browser Test Automation framework. The guide also includes various other platforms and tools that allow you to build out a Test Automation Framework.
This guide is a thorough introductory course on common models of chemical bonding from the perspective of the inorganic chemist, especially the VSEPR and molecular orbital theory approaches. In particular, the use of molecular symmetry and symmetry operations to construct molecular orbitals from symmetry adapted linear combinations of atomic orbitals is discussed.
This is a heavily annotated collection of process videos and scans, showing how different contemporary illustrators plan and execute their work - with a bias towards folks working in watercolor and other transparent paints. I hope that others will be inspired by the variety of ideas shown for planning, drawing, and painting. In my notes, I discuss paint application styles, establishment of values (darks/lights), compositional elements, and more.
"In physics, resonance is the tendency of a system to oscillate with greater amplitude at some frequencies than at others." But electrical resonance safely provides power to households and gives rise to modern radio technology, whereas mechanical resonance leads to fluttering bridges and shattered glasses. Why are its varieties so contrasted in their effects? You'll learn more about each type and find out why in this friendly comparative resonance guide!
Several articles about the nitty gritty of setting up Elasticsearch for practical applications. Common threads include the split brain problem, indexing/refresh rates, analyzers, filter construction, scoring functions, and configuration performance enhancements.
Note: I borrow heavily from www.found.no 's engineering blog which is a fantastic resource for demystifying Elasticsearch (and to a large extent, Lucene) inner workings.
Haskell is often thought of as a scary, academic language used to frighten undergrads out of the university and into the real world of commercial computing. This guide shows how Haskell is an amazing practical language which will make your programs faster, smaller, easier to maintain, and more bug free. And you will feel smart as heck for writing them.
