A chart depicting income inequality according to Thomas Piketty

From the Cia.gov World Factbook

Distribution of family income — Gini index measures the degree of inequality in the distribution of family income in a country. The more nearly equal a country’s income distribution, the lower its Gini index, e.g., a Scandinavian country with an index of 25. The more unequal a country’s income distribution, the higher its Gini index, e.g., a Sub-Saharan country with an index of 50. If income were distributed with perfect equality the index would be zero; if income were distributed with perfect inequality, the index would be 100.

Selenium is a tool to test web-pages. Modern web-pages have become very complicated with numerous stacks of pages and hundreds of links. Manual testing is tedious and error prone. Having a scripted test ensures that all elements of the web-page are tested in a repeatable fashion.

Selenium started in 2004

Selenium has been successfully testing web-pages since 2004. Selenium 2.0 arrived in 2011, 3.0 in 2016 and Selenium 4.0 was released in 2019. Selenium 4 has the usual bug fixes and feature requests. The Selenium Suite of Tools consists of the Selenium IDE, Webdriver, Grid/Hub and Selenium Side Runner. …

Selenium is a utility available in most languages to test web-pages. Selenium is able to emulate user input and collect information about the state of the web-page. As a web-page changes organically, Selenium can request web-page state and change input as required to continue a series of automated tests.

Selenium only runs with a browser component. The common browsers, Chrome, Firefox, Internet Explorer, Edge and Safari have ported Selenium versions of their Browser to use in testing and automation. Formerly, you had to find the right versions of these binaries and download them manually. “https://github.com/bonigarcia/webdrivermanager” has information about how this…

The purpose of a virtual environment in Python is to control what modules and versions of modules will be used instead of the global collection of Python modules. You will have developed and tested with a specific set of Python modules. When you release a Python product to either an internal or external customer it may not work unless you control the environment. As sometimes happens, a newer module or earlier version of a module may cause your Project to fail. It’s best to provide the customer with a specific list of Python modules and versions.

Whether it’s a few hours of work or a month of work, users often do not save their work and end up losing it. Years ago when I did desktop support my users did not follow instructions to backup their work. They told me about lost data but I could not help them because they saved their files to a local disk instead of the designated network disk being part of the corporate backup cycle.

Losing a file or a whole project is like a death.

If Ms Markle wanted privacy why did she agree to appear with Oprah Winfrey? She had nothing good to say about her in-laws and the only person she didn't libel was HRM Queen Elizabeth. She lives in a 14.6 million mansion in Santa Barbara. She and Harry signed a contract with Netflix for a series of programs about her and her family. The Queen is a billionaire and apparently has/does the support the life style of the couple. She played the race card yet she didn't identify the offending party. As far as the Royal Family being a patriarchy, that's not even true since the Monarch has been a woman for the last 63 years.
