Ethical Hacking and what it is?

Ethical Hacking and what it is?

Ethical hacking , often performed by white hats or skilled computer experts, is the use of programming skills to determine vulnerabilities in computer systems. While the non-ethical hackeror black hat exploits these vulnerabilities for mischief, personal gain or other reasons, the ethical hacker evaluates them, points them out, and may suggest changes to systems that make them less likely to be penetrated by black hats. White hats can work in a variety of ways. Many companies utilize ethical hacking services from consultants or full-time employees to keep their systems and information as secure as possible.
The work of ethical hacking is still considered hacking because it uses knowledge of computer systems in an attempt to in some way penetrate them or crash them. This work is ethical because it is performed to increase the safety of the computer systems. It’s reasoned that if a white hat can somehow break the security protocols of a system, so can a black hat. Thus, the goal of ethical hacking is to determine how to break in or create mischief with the present programs running, but only at the request of the company that owns the system and specifically to prevent others from attacking it.
People enter the field of ethical hacking in a variety of ways. Many people are very computer savvy and many, but not all, have an educational background in computer science. In some instances, the white hat has gained his or her experience by first being a black hat.
If black hat hacking was at a sufficiently criminal level, the black hat turned white hat may have served jail time before resuming a career in a more productive and positive way as an ethical hacker. The computer world is peopled with former black hats, who now hold ethical hacking jobs. Conversely, some white hats, such as Steve Wozniak, never committed any illegal acts, but simply possess the know-how and skills to analyze problems with any computer system.
With increasing use of the Internet and concerns about its security, especially when it comes to things like consumer information or private medical details, there is considerable need for computer experts to work in ethical hacking. Even sites owned by organizations like the US government have been hacked in the past, and concern about information theft remains incredibly high. Designing impenetrable systems or identifying the current weaknesses of a system are vital parts of keeping the Internet safe and information private, and even with the present legion of ethical hackers that perform this work, there is still more work to do.
Those with interest in the field of ethical hacking often acquire a lot of their skills on their own, and many have particular talent with and affinity for computers. Some knowledge can also be acquired through formal education in computer programmingThis work requires creativity, and the ethical hacker must be able to think outside of the box, coming up with as many possible ways as he or she can derive, a system might be encroached upon by black hats.

Angular JS –the framework of Java script

AngularJS is a JavaScript-based open-source front-end web application framework . AngularJS is a toolset for building the framework most suited to your application development. AngularJS was originally developed in 2009 by Miško Hevery as the software behind an online JSON storage service, that would have been priced by the megabyte, for easy-to-make applications for the enterprise. This venture was located at the web domain “GetAngular.com”  and had a few subscribers, before the two decided to abandon the business idea and release Angular as an open-source library. It is fully extensible and works well with other libraries. Every feature can be modified or replaced to suit your unique development workflow and feature needs. HTML is great for declaring static documents, but it falters when we try to use it for declaring dynamic views in web-applications. AngularJS lets you extend HTML vocabulary for your application. The resulting environment is extraordinarily expressive, readable, and quick to develop. AngularJS is a structural framework for dynamic web apps. With AngularJS, designers can use HTML as the template language and it allows for the extension of HTML’s syntax to convey the application’s components effortlessly. Angular makes much of the code you would otherwise have to write completely redundant.

Some reasons why developers should know “Angular JS”:

Angular JS supports single page applications. Angular provides all of the necessary infrastructure from routing (being able to take a URL and map it to dynamically loaded pages), templates, to journaling (deep linking and allowing users to use the built-in browser controls to navigate even though the pages are not refreshing).

Angular JS helps developers Manage Stage. It’s the “illusion” of state that was perpetuated by ASP.NET that confuses developers when they shift to MVC. I once read on a rather popular forum a self-proclaimed architect declare that MVC was an inferior approach to web design because he had to “build his own state management.”

Angular JS gives developers control. Angular enables a new scenario known as a “directive” that allows to create new HTML elements and attributes. In my emulator, a directive to create two new tags: a “console” tag that writes the console messages and a “display” tag that uses SVG to render the pixels for the emulator (OK, by this time if you’ve checked it out I realize it’s more like a simulator) is used. This gives developers their controls – and more importantly, control over the controls.

Angular JS enables a Design- Development workflow. The designer can add markup without completely breaking an application because it depends on a certain id or structure to locate an element and perform tasks. Instead, rearranging portions of code is as easy as moving elements around and the corresponding code that does the binding and filtering moves with it. Although I haven’t yet seen a savvy environment where the developers share a “design contract” with the UI/UX team.

Angular JS handles dependencies. Dependency injection is something Angular does quite well. Single Page Applications use dynamic loading to present a very “native application” feel from a web-based app.

Laravel the best PHP Framework

Why Laravel Is The Best PHP Framework In 2018?

To develop a web application available a right PHP development framework for the business can be a very difficult task because there are so many frameworks are there. We have worked and tested other PHP development frameworks as well. However, we needed some additional features and capabilities.  Laravel is the best PHP framework in 2018.

Why Laravel is used by many industries worldwide?

 

The major technical advantages which make Laravel the best out of all.

 

Reasons why Laravel is the best PHP framework:

 

 

1) Authorization Technique: PHP framework:

Laravel makes implementation of authentication techniques very simple. Almost everything is configured extraordinarily. Laravel also provides a simple way to organize authorization logic and control access to resources.

 

 2) Object-Oriented Libraries:

 

One of the top reasons which make Laravel the best PHP framework is it has Object Oriented libraries and many other pre-installed ones.

One of the pre-installed libraries is the Authentication library. Although it is easy to implement, it has many advanced features, such as checking active users, Bcrypt hashing,  password reset, CSRF (Cross-site Request Forgery) protection, and encryption. PHP framework:

 

 3) Artisan:

 

Laravel offers a build in tool named as Artisan. A developer has to usually interact with the Laravel framework using a command line that creates and handles the Laravel project environment. Laravel provides a built-in tool for command-line called Artisan. This tool allows us to perform the majority of those repetitive and tedious programming tasks that most of the developers avoid performing manually.

 

 4) MVC Support:

 

Another reason which makes Laravel the best PHP framework is it supports MVC Architecture like Symfony, ensuring clarity between logic and presentation. MVC  helps in improving the performance, allows better documentation, and has multiple built-in functionalities. Here’s how the MVC works for Laravel.

 

 5) Security:

 

While developing an application everyone has to use some or the other ways too make the application secure. Laravel takes care of the security within its framework. It uses salted and hashed password, which means Laravel that the password would never save as the plain text in database. It uses Bcrypt hashing algorithm for generating an encrypted representation of a password. Laravel uses prepared SQL statements which make injection attacks unimaginable.

 

 6) Database Migration:

 

One pain point for developers is to keep database in sync between development machines. With Laravel database migrations, it is extremely easy. Enter Migrations. As long as you keep all of the database work in migrations and seeds, you can easily migrate the changes into any other development machine you have. This is yet another reason which makes Laravel the best PHP framework.

 

 7) Great Tutorials (Laracasts):

 

Unlike others (Codeigniter, Yii, CakePHP etc.) Laravel offers Laracasts which features a mix of free and paid video tutorials that show you how to use Laravel. The videos are all made by Jeffery Way, an expert and experienced instructor. He seems to have his finger on the pulse of the essentials and offers clear and concise instructions. The production quality is high, and the lessons are well-thought out and meaningful.

 

 8) Blade Templating Engine:

 

The Blade templating engine of Laravel is very intuitive and helps to work with the typical PHP/HTML spaghetti so much better, that’s it one of the best features of the framework. If you ever have had to chop up an if statement with HTML inside of it, you know exactly what I mean. But with blade, it’s almost effortless. Here’s how it goes:

9) Responsable Interface:

Responsable Interface is a new feature added in the Laravel with the release of Laravel 5.5 in August 2017. It is a class which is used to implement the interface which can be returned by using controller method. After that, the router is going to check for the instance of Responsable when preparing the response from “Illuminate\Routing\Router”.

 

10) Automatic Package Discovery:

 

Previously in the earlier versions of Laravel, it was not easy to install packages. However, in Laravel 5.5 a new feature called Automatic Package Discovery detects the packages automatically which users want to install. Meaning that now users don’t have to setup any aliases or providers from installing new packages in Laravel. Also, Laravel 5.5 allows developers to disable this feature for specific packages.

The amazing features as mentioned above are quite enough to understand that it’s the best PHP framework in 2017. However, you need developers to start your web development project. If you have a long-term project in mind that needs attention from the scratch then dedicated development team are appropriate.

However, if you want to make some minor tweaks or renovate your site you can extend your existing PHP development team with co-developers. Regardless of the needs, you must rely on a technology partner likeValueCoders for all your development needs.

The popularity of Laravel framework is on the rise due to its incredible features. Also, Laravel provides extensive community support as well.

IMPORTANCE OF PROGRAMMERS AND DESIGNERS IN PRESENT DAY WORLD.

Technology is something which started playing an important role in the world we are living . Technology makes our life simpler by developing various softwares. And for developing these softwares we need a programmer and a designer. A computer programmer, or coder, is someone who writes computer software. The term computer programmer can refer to a specialist in one area of computer programming or to a generalist who writes code for many kinds of software. One who practices or professes a formal approach to programming may also be known as a programmer analyst. The term programmer can be used to refer to a software developer, software engineer, computer scientist , or software analyst. However, members of these professions typically possess other software
engineering skills beyond programming. Computer software designers create and test software applications used for business, scientific, industrial and entertainment purposes.
In reality software designer and developer roles are always combined. Even in larger environments where architects have separate role, the designer and developer role is joined. The designer role (when being also implicitly developer) works with existing abstractions. However when new people join the project as developers, they often indeed are developers for the short while before they grasp the design style of the project. It helps to understand that there are two different roles as it helps to understand the time it takes for new people to adapt into the team’s or project’s way of doing. Software designer role is in action when the implementation-side design is done. Software developer role is in action when the actual implementation is done. Developers write the code that actually performs the tasks. Developers are supposed to follow the agreed software design rules to keep their code aligned with the rest of the code base. And to be a designer and a good coder, proper guidance and practices are required .

DOCC Kolkata provides a homely environment and proper guidance for any individual IT or non IT to become a coder and a designer.

A Tale of Two Web Stacks: Java vs .NET

For the last few years, I’ve focused largely on desktop development doing WPF and C#. I’ve dabbled a little here and there in web development, but the lion’s share of my web development up until the last few months occurred several years ago or earlier. Recently, I’ve been doing nothing but web development, in the form of webforms primarily, but also with Java and my home automation projects here at home. One weekend several weeks ago (it was “last weekend” when I started this post) I decided to upgrade my main machine at home from XP to Windows 7, and this required me to wipe everything and start fresh. Part of this meant that I’d have to port my IntelliJ/Spring/Maven/Java setup to a new machine.

I had ported my project from Eclipse to IntelliJ (which went very smoothly — compliments to IntelliJ), so it had been a long time since I’d actually set up a web development project in Java. Interestingly, it had also been a long time since I’d done the same in the ASP world since the work I’ve been doing the last several months had already been setup from a project structure perspective. However, given my situation with the home automation project and the fact that I’m starting on Feed paper, I’m in a unique position to document my comparative experiences with both, being in the position of generally experienced developer and relatively familiar with the technologies, but not practiced at setting up these specific types of projects. I’ve done this documentation below.

Before you read on, please note that I’m not in the tank for anyone or a fan boy of any technology, company or platform. I’ve spent years developing in both Java and .NET and there are things that I like about both. I’m a happy, equal opportunist polyglot and hope to stay that way. But for me to do so (with Java and .NET at least) would require both technologies to succeed, and I see trouble on the horizon for Java. I don’t like this because I like Java. It was a nice alternative for web development when Microsoft wanted to charge me $500 for Visual Studio and who knows what for whatever else I would have needed to write web applications. I like it because it was real, big boy server side code, capable of expansion to enterprise sites and not sloppy (I’m looking at you PHP). I like it because of the vibrant and inventive community of developers committed to improving it. But, I still think dragons be coming and Java might have a fight on its hands not to become COBOL.

Career Prospects In PHP Programming at present day

PHP is a scripting language used predominantly for web programming. It is very popular mainly because it is open-source and you don’t have to buy a license or copy to install it on your computer, and the websites created using it are very dynamic and attractive. The PHP community is very active and solutions for any technical problem can be found online, either on websites, blogs or forums. According to a Netcraft survey, more than 100,000,000 hostnames have PHP coding and it is installed on more than 20 million websites and one million web servers. Popular websites such as WordPress use PHP as their publishing tools.

How long will it take for me to learn PHP? Do I have to take a course?

To learn PHP, it is very important to learn C and C++ since most of its run time code is made of C libraries and it is also scripted in C. PHP is very easy to learn – it is a straight-forward language and does not have many complexities. When I was doing my under graduation in Computer Applications, a basic PHP course was offered to us as part of extra credits. We all could write a simple, functional script in a matter of minutes. There are dozens of websites that provide free step-by-step guides to learn PHP so much so that you can become a master of the language just by self-study. A living example is my dad who, at age 70, is trying to learn PHP to improve the functionality of his website on temples which is his retirement hobby. He was able to succeed just by reading online tutorials. If a 70-year-old can do it, I am sure you can too!!

What do recruiters look for in PHP programmers?

PHP programmers who are skilled in languages like C, C++ and Java, and also keep abreast of the latest developments in mobile and wireless technologies, are in great demand. A Bachelor’s degree in Computer Science or Computer Applications is a necessary criterion to join most companies as a PHP programmer. But, a Bachelor’s degree in any stream along with a certification in PHP can also work.

What can I do as a PHP programmer?

With knowledge of PHP, you can become a Smartphone application developer and make a lot of money, while having fun at work! Various web development companies require PHP programmers to develop websites for their clients. You can also freelance and work independently for clients. If you know other related web programming languages, you can sit at home and build a prosperous career.

What is the remuneration like?

According to PayScale, web developers earn an average salary of Rs. 2.5 lakhs per annum. As a fresher, you will start at about Rs. 8,000-9,000 per month, but with experience your salary can go up to Rs 6 lakhs per annum.

Where can I find jobs with my PHP skills?

You can find jobs in:

  • Web development companies
  • E-publishing houses
  • Large corporates which have a dynamic website
  • E-commerce companies
  • Freelance websites like 99designs.com, elance.com, Sortfolio etc.
  • Digital marketing companies
  • Product companies like Google and Amazon

PHP will help strengthen your web-developing skills and make your resume more attractive to a recruiter looking to fill relevant openings. But, it is essential that you also know other web programming languages like HTML, XML, etc, along with PHP to equip yourself as an overall developer.

HOW TO BECOME A GRAPHIC DESIGNER : CAREER PROSPECT.

Graphic designers create visual communications seen every day, every minute, across the globe. Designers develop entertainment, advertising, news and features in all forms, including print publications (magazines, newspapers and brochures) and digital and broadcast media such as game machines, television, web browsers, social platforms and portable devices. As technology continually develops in complexity, so too grow the duties and skills of graphic designers. This comprehensive career guide examines the role of graphic designers, the most-common routes into the profession and related careers. It’s rounded out by a review of job growth estimates in the field and salaries, by state, for graphic design professionals.

 

Graphic designers convey inspiring and informative ideas in advertisements, brochures and other marketing communications materials. Some graphic designers work for specialized design firms as part of a collaborative team, while others are self-employed and work independently. Print and digital designers use complex graphics tools to manipulate text, images, animations and color.

 

Most graphic designers work full-time to meet deadlines. Self-employed graphic designers must be flexible, as clients sometimes need to meet during evening and weekend hours. As with so many industries, customer service and client satisfaction are keys to success. Additionally, succeeding as a graphic designer includes learning how to bid on contracts, market services and develop an ongoing client base.

 

Job rates for graphic designers are expected to grow by 7 percent during the 2012-2022 decade, according to the BLS. This growth rate is smaller than the national average for all jobs during the projection period, for a number of reasons. Due to the rapid development and deployment of digital media, the market for graphic designers in print media has severely slowed, making designers that can work both in digital and print more attractive. The BLS says jobs with “newspaper, periodical, book and directory publishers” will decline by 16 percent during the decade. On the flip side, jobs for graphics professionals in computer systems design and related services will find a strong 35 percent increase in job openings, especially in fields of web-based graphics production, portable devices and video entertainment. Competition for new jobs, the BLS predicts, will be stiff. In all, 17,400 new openings in the profession are anticipated over the projection decade.

PHP vs Java: Which is the Code for Developing a Bright Future?

Are you  thinking about really getting to know the ins and outs of a web development language, trying to decide between PHP and Java? While comprehensive web programming knowledge will serve you well, many developers become specialists, and their expertise can go a long way toward securing work, particularly with development teams.

But you might be trying to figure out which language will give you the best long-term return on your learning investment. What will best support the intricate development needs of large companies?  Which will help startups and small businesses get the most bang for their limited bucks? And ultimately, which will be in the greatest demand?

Both PHP and Java are pervasive and integral to the modern web. And since they can be used to accomplish some of the same tasks, possibly no two languages prompt as much debate over relative strengths and weaknesses. Both have serious credentials, supporting some of the world’s largest and most profitable sites. And this likely means that both will have a long and promising future in web development.

So how do you choose?  Well, if you haven’t already, you might start with a comprehesive survey course in web development to get a good overview of how the languages work within a larger context. But as you begin to explore these languages, here are some ideas about them and their differences, drawing from the experience of developers who use them regularly.

One of the primary structural differences between PHP and Java is the difference between strongly- and weakly-typed languages. Java is a strongly-typed language, meaning it requires explicit statements of intent to function and that it is backed by a compiler. At the highest level, you can think of this as meaning it has strict expectations on how you express inputs and outputs. If these exact expectations are not met, the compiler will fail and the program will not work until errors are resolved.

PHP, in contrast, is weakly typed, essentially meaning it is more flexible and reliant on “common sense programming” in how a task is accomplished.  While this may sound more attractive because it requires less formal knowledge, some contend that it complicates certain tasks, particularly in object oriented programming, with its lack of standards.

Ultimately, these characteristics imply that java can be a good choice when development is complicated and relies on teams of professional developers. Rather than making work more challenging, the precisely defined standards allow for easier understanding and greater efficiency among teams. On the other hand, PHP is more accessible to inexperienced programmers. If a web product intends to allow users to work with the code (such as web and blog creation software or small business sites) PHP can fit the bill nicely. It can also be a nice economical and nimble choice for small teams using agreed coding standards and when dealing with simple functions.

You have likely taken away, thus far, that PHP can be characterized as fast, flexible, and free.  Unless, of course, it leads to jam-ups caused by a lack of coding standards, this is a fair statement. And there a few other facts about PHP that further define these traits.

First, an advantage of PHP is that, aside from being free in terms of coding standards, it is free of cost. The open-source language is available on virtually every Web-hosting platform for anyone to use.  It is the programming language of the people!

Then, to further define PHP’s flexibility is the fact that it works universally, across platforms. The reason for this is that the code is processed entirely on the server side and delivered as dynamic content to the viewer. For large scale operations that need to work on every system architecture, PHP can be the way to go.  It can provide an easy method to ensure people are seeing what they should, wherever they are.

Importance of Web Developers in present days and DOCC Kolkata, building Web Developer Career.

Web Developers create web pages and web-based applications.

Web developers build the web pages and web-based applications that comprise the Internet. A basic web development work-flow includes collecting or creating web content (copy, images, videos, etc.), planning web site layout and navigation, coding the actual web pages, then testing and optimizing the website for superior user experience and optimum performance.

Successful web developers are fluent in the programming languages that fuel the World Wide Web. All web developers need a command of HTML, Java script & CSS. It’s also helpful to know a server-side programming language, such as PHP, Microsoft .Net Visual Basic, or Java 2 Enterprise Edition (J2EE) to develop more complex applications. Web developers can further distinguish themselves and increase their earning potential by learning and certifying in one or more of the leading database systems, such as My Sql, Microsoft SQL Server, IBM DB2 or Oracle to write web apps that interact with databases. Learn more about web developer education requirements and compare the top-rated web development training program in the India.

Web development projects require frequent revisions and enhancements, so web developers need patience as well as strong communication skills to interact with team members and clients. Creativity and an understanding of color theory and design concepts will also increase your value as a web developer. Web development jobs exist in all settings, including enterprises and government agencies, small to medium businesses or working alone as a freelance web developer.

Graphic Design vs. Web Design: Which Career is Right for You?

Are you naturally creative? Do you have a knack for thinking outside the box? Do your friends often come to you for tips on color palettes or accessorizing outfits?

If so, working in the design industry may be one way to turn your imagination and originality into a career. Because what could be better than earning a paycheck for something you’re already passionate about?

There are many specialties that fall under the umbrella of the design industry. For example, a fashion designer is different from  a  textile designer, which are both very different from an interior designer.

While they all share similarities, there are distinct differences in these fields. Understanding these distinctions is an important part of determining what type of career you’d like to pursue.

If you’re looking for an opportunity to combine your love of technology with your passion for design, you’ll probably find yourself faced with a tough choice: GRAPHIC DESIGN  versus WEB DESIGN.

It’s important to have a comprehensive understanding of each field in order to determine which best suits you and your personality. Conducting a little extra research now can help prepare you for success in the long run.

We created an infographic that outlines these two common—and commonly misunderstood—career paths.

Opinions from the experts …

Although aspects like job growth and salary potential are definitely important, they shouldn’t be the determining factors in your quest for the perfect career. After all, if you’re going to be investing 40-plus hours per week into this job, you might as well enjoy what you’re doing, right?

We got in touch with some professionals in both fields to hear their thoughts on the debate over graphic design versus web design. These thoughts came straight from industry experts, so consider them insider perspectives.

After gathering their thoughts, we broke them down into bite-sized chunks to make them easy to digest. These tidbits should help give you a better idea of which career suits you best.

Graphic designers …

1)Put the art first

2)Have a one-way relationship with their audience

3)More artistic (i.e., sketch with a pen and paper)

4)Emphasize visual theory in their designs

5)Must focus on how a design communicates a message to its audience

6)Need to know how each element of a design translates to print

7)Have one shot to get a design right once it’s printed

Web designers …

1)See the art as a way to leverage technology

2)Have a mutual interaction with their audience

3)More technical (i.e., coding and programming)

4)Employ an engineering approach to their designs

5)Must predict how a design will make its audience feel and react

6)Need to know how to design for versatile mediums (i.e, laptop, tablet, smartphone)

7)Can develop and enhance their work over time
So after comparing graphic design versus web design on multiple levels, you should be able to confidently determine the field in which you’ll excel. Once you decide which creative path you’re interested in traveling, take a moment to learn more about the education that can jumpstart your journey.
