11 "Faux Pas" That Are Actually Okay to Make With Your python course london

[Renwick Goold]

Technology is an unavoidable necessity that has opened the expectant and long anticipated heart of the universe to exciting and amusing innovations. It has always dared to be at the forefront and vanguard of inventions, technical creativity and a novelty at its peak. One would almost not find a single company that has not been influenced by technology. Undoubtedly, technology is the cruise of this Go to this website era.

However, programming languages as an aspect of technology are vast and to select preferred ones as the most popular amongst a hundred of equally popular ones is, no doubt, an incredibly difficult and challenging thing to do, knowing fully well that such selections have to be done carefully and most importantly, by being unsentimental. Below are the lists of the most popular technologies:

Java language

Java programming language has been on the top chart since its introduction in the '90s. Most the world's renowned companies use Java to build their mobile and desktop apps and also their webs. Similarly, Java can run almost on all systems. Wow! That is huge! Also, they are the most popular language for Android gadgets. Little wonder why Android applications are Java-based built. Java has something very peculiar and interesting. The long-time and seemingly old-fashioned rendition of languages can run without stress on it because newer versions have introduced. What a programming language Java is! This simple characteristic of Java has and will always put a smile on the users face as they will not have to bother themselves with any code rewrite once newer versions of Java are out.

"C" language

"C" programming language is also a popular programming language. Invariably, it is one the oldest programming languages that have been adopted by technology's huge brands such as Apple, Microsoft, Oracle and many more. In this present age, there is hardly a thing that we make use of technologically, this programming language has not influenced that. The "C" programming language possesses qualities that enable it to work, without a second thought, for operating systems and also systems that are hidden. More so, it is amongst the first most popular programming languages today.

Python language

Python programming language is different in a way. It has a fighting spirit of consistency and steadiness, thereby, struggling its way out to be at the top of the chart. Astounding! Interestingly, python is a significant and widespread language in some very relevant technologies in this present point in time. Cyber-security is one essential software of this age, and it will tickle you to know that Python runs it. It is used as a preliminary software for beginners at our tertiary institutions for learning and also, artificial brainpower.

JavaScript language

JavaScript, no doubt, is one of the most popular programming languages ever known. JavaScript enables those that are developers to include responsive impression to pages on the web. Many times than none, it works with HTML to create documents and websites. It is quite simple and easy to operate and this why businesses that are newly starting are opting in for JavaScript.

Ruby language

Ruby is considered the best for new companies and technology developers that are just beginning. There are many reasons why it is marked as very important. The way words put together on Ruby is quite beautiful and attractive to behold. This beauty allows the technician accompany more work with a little code. Again, a running web app does not take as much time as how others are framed, and this is why the beginning tech developer loves and is familiar with the language.

This article examines how drag and drop programming and other forms of interactive software development can assist end-users to program via the web. AJAX (Asynchronous JavaScript And XML) software is used to provide a Web 2.0 style interactive interface. This can be linked to applications and to Semantic Web information.

Lieberman [1] blames end user programming difficulties on hard to understand programming languages and techniques and argues for visualisation and translation to code to enable end-user programming. To make end-user programming easier it is possible to develop high level visualised templates and translate these into program code. The Dagstuhl report [2] argues that existing programming languages are not sufficiently dependable for end-users to reliably use. De Souza [3] argues that the goal of human-computer interaction (HCI) will evolve from making systems easy to use to making systems that are easy to develop. A template system will assist in this. Ko [4] explains that end-user programmers must be allowed to focus on their goals, and an important part of the solution is to visualise the whole program execution not just the output, so it is necessary to show the user the whole program flow not just text based bug reports. A simple illustration of the techniques that can be used to further this research area is a demonstrator for meta-programming of XML (eXtensible Markup Language) based drag and drop trees [5], this example was created with AJAX (Asynchronous JavaScript And XML), a Java applet or Python were other options investigated.

The code acts as a translator between the XML representation of the trees and interactive graphical representations. This allows open standards platform independent end-user programming. The example is based on the Scand dhtmlxTree [6] and this makes it possible to enable many other programming actions such as adding and deleting nodes, and to create other controls. Repenning [7] argues that visual programming languages using drag and drop mechanisms as a programming approach make it virtually impossible to create syntactic errors, allowing for concentration on the semantics", and Rosson [8] also advocates this technique. Such techniques could be used with other Semantic Web-based information representations implemented with languages and structures such as XML, RDF (Resource Description Framework), and OWL (Web Ontology Language), and provision of other controls. These controls could then be used as graphical components of a simulation system made available over the web. As well as being used for web-based visual programming an environment such as this could also be employed as an interface to PC based software, or as a translator between systems. Semantic languages provide a higher level declarative view of the problem to be modelled. Coutaz [9] explains that "An interactive system is a graph of models related by mappings and transformations." This would fit in well with the structure of RDF, which is also a graph structure.

It is important to investigate new ways of enabling collaboration between all those involved in software creation and use. The use of Semantic Web languages for declarative programming can ease the translation between different representations of information, and ease interoperability between systems. This translation or 'Program Transformation' allows for writing in one representation or language, and translating to another. This is particularly useful for language independent programming, or for high level and end-user translation to a language more easily interpreted by computer systems. The solution to many interoperability and software problems involves programming with Semantic Web languages rather than just using them for information representation. This will make translation for interoperability easier and more reliable, and further improve the maintainability of software systems.

The research will involve using and building a visualised Semantic programming layer on languages such as AspectXML, XForms, SPARQL, and XQuery all explained in [10] and Meta languages [11][12] to create software and to build an environment for high level end-user programming. This programming environment can be used for creating programs and an environment for end-user programming. The environment can be computer language and system independent as one representation can be translated into many computer languages or Meta languages. Tools such as Amaya [13] can be used for creating and editing Semantic Web applications and documents. This research is a test case for an approach of collaborative end-user programming by domain experts. The end-user programmers can use a visual interface where the visualisation of the software exactly matches the structure of the software itself, making translation between user and computer, and vice versa, much more practical.

To enable generic end-user programming functionality it is important to develop 'information representation languages' based on Semantic Web declarative programming languages. Standardisation in XML/RDF enables use of declarative rules for web services. This environment also has to provide a visual development interface for end-users in a similar way to that of Unified Modeling Language (UML) for professional developers. Repenning [7] and Engels [14] argue this.
