Learn Computer Software with Free Lessons & Tips

Hi there,

I am sure you all would have played video games for killing time. Do you know how these are developed?

I am going to introduce you to some details of the gaming industry.

Gaming is a serious business, and many companies like sega, electronic arts, PlayStation (sony) and Microsoft Xbox have created platforms in which game developers can program.

The most exciting developments in the gaming industry happened around 1995 with the introduction of Windows 95. It caused a revolution in gaming, and www enabled people to download games on their PCs and play.

Soon graphics cards that did not block other programs due to graphics processing in the processor came about. They were parallel processors and could render graphics at speeds and resolution that were unmatched. Due to ease of programming and the flexibility of changing graphics pipeline parameters, these processors started shipping along with ordinary PCs and laptops.

The latest trend is to have an on-chip graphics processor such as an Intel HD graphics processor. Those games that demand high-end machines are no longer played on ordinary PCs anymore.

Gaming laptops such as MSI, AMD Ryzen, Lenovo ThinkPad, Lenovo legion, dell g3, Dell g5 etc are all costing a bomb.

With the availability of cheaper and more powerful processors and the possibility of playing games on mobiles, we can develop games that people can play anywhere they are.

Once iPhone and android platforms became popular, we see mobile game app development gives employment to many.

Training yourself in fields like game development is a long drawn process.

Game development has distinct phases:

1. Conceptualization, designing models, storyboarding, game strategy design
2. Development and testing
3. Publishing and marketing
4. Sales and maintenance

Gaming studios in India are highly prized as there is a lot of talent and availability of engines like unity and unreal. These enable us to use AR/VR extensively in our games and publish our games to multiple platforms.

Python breaks into the top three programming languages in the Tiobe Index for the first time.

Hi, It completely depends on what your requirement is, are you looking to crack a certification exam or  looking for job assurance or already have an experience and just want to upgrade or brush up your skills you can choose accordingly.

If you are looking for IT experience or want to move to Java, there are lot of experienced IT professional providing the Java training online or near Yamuna Vihar. You can find by just posting your requirement.

“There is more to know for career advancement rather than focusing on codes and its challenges to become a successful developer”.

A developer is the one who creates software application by writing, debugging and executing the source code. He may be also referred as the computer programmer, software developer, software coder, engineer, or the programmer.

The programs created by him is bound to help the business to become more efficient and also provide a better service.

If we consider the field expertise, generally, a developer carries a relevant bachelors/masters degree in fields like information technology, programming, computer science, or other IT related studies.

A self-motivated professional possess a dynamic experience on key programming languages like C, C++, C#, Java, JavaScript, Php, Linux, Python, Smalltalk, UNIX, HTTP, XML, and other software testing tools.   

In brief, it is agreed that a developer’s main focus lies in the coding and its related challenges. Still, coding, coding, and nothing but coding will not make a successful developer. It demands lateral knowledge and capability from a multitude of similar and ancillary disciplines.

Let us investigate further, and know how one can become a successful developer.

Understanding Codes as a Business Language

The successful developers understand the company work at the business level. They are able to translate the business language to the technology and the other way round. The code’s contribution must be targeted to the user or the customer and not the repository.

An overview of the goals, objectives, and impact of the project helps to code better. And it is true that codes drive the business.

And, mention not to say, necessary skills for coding like the programming, backend, non-technical, functional programming skills, and, etc., are the part of the market scenario.

Logical Thought:

A logical mindset, knowledge of statistics/mathematics, algorithms, attention to details is appreciated and anticipated by the employer. It is a surprising factor that programming is about thinking and not writing codes. One function one purpose thumb rule has to be followed so that anyone or the developer himself when come back to read, it is easier to follow.

In this scenario, personal research and education are highly recommended. A strong developer is one who is logical and implements a methodological approach to resolve an issue[s].

Discipline is NOT the Other Part, but The Part:

A Disciplined developer has the following qualities:

• Listens first and then speaks.
• Admits and acknowledges the unknown part.
• Aware of the technical debt when speed matters.
• Joins the code review session and embrace processes.
• Acknowledge the focused time for development.
• Ability to focus on the shared goal of a project.
• Research to solve a hard problem.
• Alert about ‘ego’ that turns a programming problem as a productivity drain.
• Ready to take online help to solve the problem rather than copy-paste a code.
• Understands that development is a continuous learning and none is a master but an expertise.
• Acknowledges that learning does not stop and is open to learning.
• Deliberately is ready to stretch the boundary of skills.

Marketing is a part of Success:

A few of the marketing tips to become a successful developer are jotted down below.

• Setting up a blog and writing regularly is highly appreciated.
• Though there are developers who have not seen a day unemployed, it is recommended to go open source.
• Change of job every six months or staying in the same job for more than six-seven years is not recommended.
• Understand the market trend and update programming skills accordingly.
• Able to write documentation or presentation.
• Command a high salary by being able to give the presentation in public.
• Recommended to learn more than one language instead of being a narrowly focused expert.
• Use the tools to solve coding problems.

Security:

The organizations are adopting the cloud, big data, machine learning tools, and other feasible solutions. This calls for security, compliance, and governance for a proper and secure administration. At this stage, the developers need to safeguard their codes. They are expected to possess knowledge in business intelligence, analytics, and other solutions.

Understanding Different Types of Development:

Moving further, there are different types of development. Depending on the interest, one can take up the career in various development fields like the Web Development, Mobile, Desktop, Games, Embedded Systems, Cloud, Automation, and more.

1. Web Developer: We find several web development roles such as the Full stack developer; Front-end developer; Back-end developer; UI developer and more.

Furthering the specialization, they are specified as eCommerce developer. Based on different eCommerce platforms/programming language, they may be called as Magento developer, PHP developer, WordPress developer, PrestaShop developer, Java developer, HTML developer, Drupal developer, and, the list goes on.   

2. Mobile app developer: Working on the different operating system, they are called as the iOS app developer, Android app developer, Augmented Virtuality- AR app developer, Windows app developer, Virtual Reality- VR apps developer, and more as specified to the field.

3. Desktop Developer: Desktop development involves the user experience part of the solutions. This implies the guidance level provided for developing client-side applications, web applications, rich internet applications, or the mobile device applications. The developer is mainly involved in creating composite desktop and mobile applications, web client application development, offline-capable applications, and more.

4. Games developer: Game developers are specifically known as video game developers/designers. They are involved in creating varied aspects of the game that starts from concept ideation to story writing. It includes the programming and the coding as well.

5. Embedded System Developer: The main responsibilities of an embedded systems developer include designing and implementing software for embedded systems and devices; design, develop, code, test and debug the system software, and so forth.

6. Cloud developer: The cloud developer is subject experts on architecture for team development, project management, software tools, and also the subsystems designer. They manage the data storage and data warehouse system.

7. Automation developer: They are the software developers who can design and write the programs for running tests on the existing or the new software. It forms an integral part of the software development cycle.

Career Path in Development:

The career path in development is schematically represented as below.

Junior Developer→Senior Developer→Lead Developer/Architect→Developer Manager/Project Manager/Project Manager→Senior Leadership like CTO, VP or the CEO.

It is noted that the finding and keeping up a job as a programmer is difficult. One can expect a peak and also an inevitable decline. In brief, the effective period of being a successful developer is limited unless and until there are self-promotion and self-learning.

Mention not to say, the developers must understand the possible slip in their career role on a long-term basis, and actively climb up the ladder to stay ahead in the field.

Conclusion:

The Darwinian principle ‘Survival of the fittest’ holds good here too.

It is recommended to update oneself by learning more programming languages and possess non-technical skills as well to thrive in the industry. Self-promotion and self-learning is a necessity in this competitive world and one has to uplift oneself and stay on pace with the existing culture.

First of all the role of a UI developer is that of a combination of a web designer and a web developer. The language skills required for a UI developer are front-end web development languages like HTML, CSS and JavaScript and modern application programming languages like JAVA, .NET, AJAX, XHTML and Ruby. The demand for UI/UX developers is increasing because every company is resorting to a digital presence for greater reach. Consequently, they need more and more UI/UX designers and developers to create their websites.

Language to use: Any language that you are learning.

Interface: Web or Desktop

Function: Simple calculator (9 digits + symbol) with 1 Memory storage with possible function of + - * / 

Error Handling requirement: All invalid entries & calculations to be gracefully handled

Client: The client is an experienced computer user. We therefore assume that users will have basic knowledge of using the mouse and keyboard

Data Input: We assume that data input will occur only via the keyboard and the mouse.

Output: All output will appear in a text display area similar to a calculator’s LCD screen. 

Output Event: Clicking a button representing an operation causes the display area to be updated. Results will be presented to at most 7 decimal places accuracy.

Operation: The application will present a visual keypad where one digit at a time can be added to the display by using the mouse to select one of the digit buttons. An optional negative sign can be entered before any digits have been entered; thereafter, the negative button will be ignored. As long as an operation has not been requested, digits will be added to the righthand side of the current number. This number will be displayed in the display area as it is composed. Number entry restarts after any arithmetic operation, result display, value storage, or clear operation is requested.

Operations are represented by buttons on the calculator which specify the arithmetic operation to perform or the storage of a value for future recall. In general, the entry of a number is terminated by clicking on one of the operation buttons.

Display: The display result operation is requested by clicking on the “=” key. If a value has been “remembered” by requesting one of the arithmetic operations, then the remembered value is combined according to the requested operation with the value currently in the display. The display is updated with the new value, and the calculator is made ready for the entry of the next number.

Clear: Clicking on the “Clear” button erases any value that appears in the display area and resets number entry. Clear does not affect the “remembered” value or the operation that has been requested.

Appereance: The interface of the calculator should be as close to the appearance and operation of a physical calculator as possible. The appearance of the application on the two platforms should be a close to identical as possible.

Testing: Include all the possible test cases along with the documentation (steps & results) as a part of output.

In short, it should be fool-proof, should not crash in any way possible, should provide all valid error messages, and result as per the rounded figures possible for a 9 digit calculator.

A lot of students (count me as well) in their final year of IT course are confused and overwhelmed about their Project development. Final Year IT Projects are a crucial milestone in every IT students educational phase. If project development is tackled in a unorganized fashion, it can mess up your entire final year score (as final year project have a big share of marks and affect your overall score).

You must have heard about Project Development Phases in Software engineering. Well, it does have a lot of importance in your own student project development so make sure you take that subject seriously.

Here are typical Software development phases:

• Requirement Gathering Phase.
• Analysis Phase.
• Design Phase.
• Coding Phase.
• Testing Phase.
• Implementation & Maintenance Phase.

I will be explaining you the importance and meaning of all these phases in terms of student project’s point of view and how should a typical IT student look at these phases for his/her project development:

• Requirement Gathering Phase:
  • This is usually the first initial phase of your project development so it is very important to go ahead with this step carefully. What this phase states from a students point of view is that you need to decide on a project topic. 
  • Project topic selection can itself be tricky and the best way to tackle this is to ask yourself will your software, web-application help solve peoples problems (after all the very important mantra of software development to remember is customer is the KING).
  • Once you select a project topic you need to check of similar projects in the practical world and check on their success and feasibility.
  • If your topic doesn’t seem to solve real practical problem, chances are your project won’t be of any relevance.
  • Talk to people interested in software solutions and find out their technical problems (take a survey) and maybe you might find your desired project topic.

• Analysis Phase:
  • Once Finalizing of your project topic is done, you need to validate it ie check for various feasibility parameters.
  • First of all check whether the project is actually implementable. A lot of times students have big ideas which in the end prove to be useless in terms of practical usage (this is usually because of lack of experience so don’t get offended students).
  • Second important factor to check is which technology to be used to develop the project. Select the one which you are comfortable with since its your first project you need not learn something entirely new and then fall short of time. Usually students find ASP.NET, C#.NET better over conventional JAVA technology but that is all personal choices. Bottom line select the one that you are comfortable with.
  • Time constraint is also important to check on. Usually this parameter is hard to predict on since it is your first time however it is important that you plot down a rough timeline of your entire project development and strictly follow it. You don’t want to submit your project late for sure after so much hardwork right!
  • Generally this phase ends by a Project Synopsis where you create a soft-copy of your project analysis.
    

Students who go ahead with the first 2 phases in a proper organized manner are more likely to get their projects working successfully and more importantly with high efficiency of management.

• Design Phase:
  • This Phase is many a times overlooked by students and trust me they find it difficult to go ahead with the actual coding of the projects.
  • The reason is, when you have a rough design, model, prototype in front of you, it is easy to code the same. 
  • When you plot your visual ideas and make rough designs it can also help with finding out some design flaws and errors which in future could be more troublesome to solve after you have actually coded for the same.
• Coding Phase:
  • Well This phase requires the least explanation I believe although you need to know 2 very important tip here:
    
    • First: When coding always use comments and proper indentation (i know students usually don’t since i as a student didn’t do it).
    • Second: After completing one module try and run it instead of coding the next module or entire project.

• Testing Phase:
  • This phase is also very important in real life situations as well as for students. Why so?
  • What if you project doesn’t work during the final project presentation just because you had to show it on college computer system?
  • So make sure you run your project in 2 or 3 different environments.
  • Specially for Android projects, check the application at least on 2-3 different versions of androids with different screen resolutions.
  • Do not test your project all by yourself. Always ask teachers, guides to do a second round of testing, maybe they’ll spot some bugs which you couldn’t and yes mist likely they will.
  • If its a live project let the client test it as well.

• Implementation & Maintenance Phase:
  • This phase is where you actually run the project. 
  • Maintenance is usually not to be worried from students point of view, however if project is going to have huge database load it is necessary to check on performance regularly till your final project presentation to make sure it doesn’t crash at the crucial moment.
