Selenium Remote Control was a refactoring of Driven Selenium or Selenium B designed by Paul Hammant, credited with Jason as co-creator of Selenium. The original version directly launched a process for the browser in question, from the test language of Java, .NET, Python or Ruby.
One example of this continued division of use is the type tool in Adobe Photoshop, where the return key produces a new line while the enter key ends editing mode. Another is Mathematica, where the Return key creates a new line, while the Enter key (or Shift-Return) submits the current command for execution.
In documentation and instructional design, tutorials are teaching-level documents that help the learner progress in skill and confidence. [7] Tutorials can take the form of a screen recording (), a written document (either online or downloadable), interactive tutorial, or an audio file, where a person will give step by step instructions on how to do something.
From Java 8 onwards, the default keyword can be used to allow an interface to provide an implementation of a method. do The do keyword is used in conjunction with while to create a do-while loop , which executes a block of statements associated with the loop and then tests a boolean expression associated with the while .
An 8-plate 160 V 450 mA Federal brand selenium rectifier. A selenium rectifier is a type of metal rectifier, invented in 1933. [1] They were used in power supplies for electronic equipment and in high-current battery-charger applications until they were superseded by silicon diode rectifiers in the late 1960s.
Free software projects, although developed through collaboration, are often produced independently of each other. The fact that the software licenses explicitly permit redistribution, however, provides a basis for larger-scale projects that collect the software produced by stand-alone projects and make it available all at once in the form of a ...
Selenium is found in metal sulfide ores, where it substitutes for sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores. Minerals that are pure selenide or selenate compounds are rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells.
In 1866, Smith developed a method for continually testing an underwater cable as it was being laid. For his test circuit, he needed a semi-conducting material with a high resistance and selected selenium rods for this purpose. The selenium seemed to do the job properly, except in actual use, the device gave inconsistent results.
