Ruby Scripting

HTML stands for Hypertext Markup Language and it is the main language used for the creation and display of website pages in a web browser. Actually, browsers are created especially to read HTML files and transform the HTML code into the web pages we see every day on the Internet. With the help of the HTML script on web pages can be embedded images, videos and other objects as well. The markup also allows the easy implementation of other scripts in the HTML code including JavaScript, PHP, and CSS, which add to the capabilities, interactive features and design of the page. HTML files have the name extensions .html or .htm. A basic HTML function is the embedding of links (hypertext) in a web page, so links can be attached to any piece of text on the web page or to an image. This is done with the use of HTML tags, specified for that task. The tags are exact predefined instructions put in angle brackets like “<“a >.

PHP scripting refers to a language that can be embedded in HTML. A big part of its syntax is borrowed from C, Java and the Perl languages. Of course, it has some unique PHP-exclusive features thrown in. The language was created so it is possible for web developers to code dynamically generated pages easier. The code is parsed by a server with a PHP script processor module. The end result is the generated website. It’s also possible to manipulate it via command-line interface due to it’s an integrated capability, plus it can be used in separate graphical applications. The PHP script can be installed on most modern servers and also as a separate shell on most popular OS’ and platforms for free.

Perl Requirements

Perl script can be installed on almost every computing platform in the world, from ancient 486 desktops to supercomputing clusters. First, you have to choose where you’ll be running your Perl scripting applications from. If you’re mostly interested in coding web apps, you’re better of choosing a web hosting company that has Perl script running capabilities pre-installed on their servers (most hosts have that enabled). By choosing this route, you must make sure that you have SSH or telnet shell access to the server where your Perl scripting applications will run from. Windows users can use PuTTY, a telnet/SSH client, to log into their user accounts on the server. Using telnet is highly unsafe and should be avoided because your username and password are being broadcasted over the web visible in plain text. SSH is a secure protocol designed for running shell sessions on remote hosts and is highly recommended.

Programming in C

If you are a programmer, or if you are interested in developing and learning the C programming language, here are a few things to consider that might be helpful in the future: You will have the ability to read and write code for a many platforms — everything from micro-controllers to the most advanced scientific systems can be written in C script, and many modern operating systems are written in C script. The jump to the object-oriented C++ language becomes much easier. C++ is an augmentation of C, and it’s almost implausible to memorize C++ without studying the C scripting language first. The C scripting language has been around for many years and has won widespread acceptance because it gives programmers maximum control and efficiency and is an easy language to learn.

The C++ language is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language (or C++ scripting language). C++ (read as “see plus plus”) falls in the group of intermediate-level languages, as it includes a mix of both high-level and low-level language features. The C++ language was conceived by Bjarne Stroustrup who laid its foundations in 1979 working for Bell Labs. The language builds on object oriented features, like classes, and adds other improvements to the C programming language. It was originally called C with Classes but was renamed C++ in later in 1983, as a wordplay including the increment operator.

JavaScript Usage

JavaScript is one of the widely used scripts, especially for web applications. Every web company needs JavaScript to add more functions to its sites. In web pages, JavaScript can be used for interactive features, animations, media playback, data validation, receiving or sending data to the server without reloading and easier tracking of user activity. However, JavaScript code is also used for various software applications unrelated to the web.

Enable JavaScript, JavaScript Engines

JavaScript engine or interpreter is the software that enables the execution of the script in web browsers or other applications on your computer. JavaScript engines are commonly used in browsers, so you don’t have to do anything to enable JavaScript (it’s enabled by default). Still, you can easily disable the script or enable it if necessary from the browser itself. In Chrome you can enable the JavaScript engine from the Settings menu (in the Privacy section there are Content settings), you can also disable the script completely or for certain sites. In Firefox go to the Tools menu and select Options, a pop-up window will appear, click on the Content tab where you will find the Enable JavaScript option. The same settings for IE are also in the Tools menu, the Internet Options section where you can find the security settings, click the Custom Level button and find Active Scripting in the list.

Python is one of the widely used programming languages that can be applied in various cases. It’s dynamic, interactive and thus easy to interact with. The Python script is interpreted, which means that the code is processed in runtime, only some parts of the Python code are checked at compile time. The Python programming language is object-oriented with a flexible structure, greater readability and clear, simpler syntax. Python is case-sensitive and takes into account the indentation in the code. So, the amount of whitespace defines the end of blocks and statements. If the indentation is wrong the Python interpreter will flag it as an error in the syntax. Python comes with lots of free documentation, which simplifies its use for both amateurs and professionals. This package of ready-to-use modules is the Python Library and can be found on the official Python site along with lots of Python tutorials.

Ruby on Rails Scripting

Rails are portrayed as a language that has its own spirit. It isn’t designed to be good at everything. It has its own way of doing things and shapes all of its components around that way. This doesn’t mean you can’t do anything differently if you have to, but certainly, it’s going to be easier if you do things “the Rails way.” That way of programming turned out to be fitting not only for Hansson but for many other developers too, another major point for the wide acceptance of Ruby on Rails programming. The important thing in the development of Ruby on Rails was to increase programmer productivity, the performance came in second place. This has caused many disputes and opinions that Ruby on Rails scripting isn’t good at scaling. This is so due to the fact that Ruby on Rails was seen as a solution that could solve all the problems of programmers and web developers. When the group that developed Ruby on Rails didn’t deliver on those rather high expectations, a part of the community got somewhat disappointed. Still, today Ruby on Rails scripting is one of the most widely used Web frameworks and powers many famous websites and services like Twitter and Groupon. Other large sites powered by Ruby on Rails include Github, Scribd, Shopify, and Basecamp. The latest research for 2012, shows that over 200 thousand websites are powered by Ruby on Rails.

ASP.NET is a software framework designed especially for the easy creation of websites and various web applications. ASPNET allows programmers to use any of the .NET languages (CLI languages) to make their sites. You can easily use .NET languages in the ASPNET framework and they will work together without any problems. Of course, you can freely use any of the popular script languages for your web applications as well: HTML, CSS, JavaScript, etc. The ASPNET framework has been developed by Microsoft and released in 2002. ASP.NET employs pre-made controls that you can use simply by automatically implementing them in the page. With the ASPNET controls, you can easily apply forms, tables, buttons, calendars and all kinds of interactive features. You can change their properties, events, and methods freely and create custom ASPNET controls if you want. The creation of websites with ASP.NET is also simplified by the extensive controls and classes libraries available.
