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.

PHP Programmer: Career Profile

Learn about the education and preparation needed to become a PHP programmer. Get a quick view of the requirements as well as details about degree programs, job duties and necessary skills to find out if this is the career for you.

PHP programmers design, build, test and debug database-driven, Web-based applications in the PHP scripting language. These applications are dynamic, and users can interact with them. PHP programmers usually need a bachelor’s degree in a computer science field, and they should also know how to code in other programming languages and work with database packages. Individuals may opt for certification in a variety of programming languages.

PHP Programmer Overview

PHP is a server-side scripting language that enables users to interact with databases underlying web pages. Most PHP programmers supplement their skills with knowledge of software that PHP works with to make Web pages dynamic. This software includes HTML code, other scripting languages and some of the essential programming languages. Working mostly with database and storage applications, accomplished PHP programmers are also familiar with database packages such as MySQL and Oracle.

Job Duties

A PHP programmer is responsible for designing and implementing website functions by writing PHP script code and templates. The programmer combines PHP with other programming protocols to design, build and manage such application packages as report generating protocols, games or e-commerce shopping carts. The PHP programmer uses testing and debugging skills to ensure that these and other Web applications are running smoothly.

Job Outlook

The BLS reported that job growth for software developers should be excellent from 2012-2022, with a projected job growth rate of 22%. The field of computer programming will experience more modest growth, with a projected rate of 8%. By expanding their knowledge base of newer technologies, such as cloud computing and programming languages, PHP programmers may become software engineers with careers that could advance into managerial positions. If you want to learn Web development very easily then PHP is the language you must seek to master.

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.

UI VS UX DESIGN: WHAT’S THE DIFFERENCE?

Learn UI/UX Design from DOCC kolkata

UI is the saddle, the stirrups, and the reigns.

UX is the feeling you get being able to ride the horse, and rope your cattle.

At least that’s what they used to say in the olden days. Rather, that is what I wished they’d say. Despite how simple that may have sounded, there are many complications and misconceptions when it comes to the differences between UI and UX design, and they cause the design community to go into quite a stir whenever they are brought up.

An interesting note to that is that I’ve found the people who work at jobs with titles such as Interaction Designer to get paid more simply because they know and act on the differences between those two fields (typically harnessing a little of both). And in fact, I think there are more differences in the people behind these roles than the ideas behind UI and UX design.

Let’s jump right into a standardized definition that we will try to metaphorically elaborate on. Defined very simply a User Interface design is the part of the product that faces the user when he looks at the site, and the User Experience is how they feel when they look at the site, aka the broad scope.

More pointedly, good user experience is the art of a drill going through wood, or a surfboard gliding through water effortlessly. The feelings those give you is unparalleled because they just work, simple as that. Though, in contrast, the shape of that board that helps it make those turns on the wave is good UI, and the surfwax on the top so you don’t slip off is also good UI. In short, the ENTIRE package is what makes it good UX, whereas good UI is always a very important inner-element of that.

Just look at that image; that is such a glorious illustration of exactly how much is incorporated in User Experience design. Now you can tell why the people in these roles have to be able to think critically and creatively on an almost constant basis. Though, don’t be thrown off if you are a bit confused thus-far, because we have indeed mainly related UX and UI design to physical products like the surfboard, or animals like the horse.

The reason for that is, this is obviously a bit of a confusing topic, and it is mainly that way because it is heavily fractured. That is, little pieces of one make up the larger view of the other, and that can be sort of confusing or challenging to a lot of people. But even designers have a hard time with it, so don’t feel let down.

Let’s imagine that we convert those ideas we already spoke about into the web or mobile spaces. The UI would be a series of buttons and how they look, and the UX would say that button should physically press down when you click it. The responsiveness of being clicked, and then having the button pressed down on a 2D website is so satisfying after all, how could a designer not do it? Well, it happens all the time, and I think we get spoiled by the ones that do.

For instance, I have been to tons of sites that have nice big beautiful buttons with shadows under them like they are just itching to be clicked on, and then when you do, they don’t inset into the page. No responsive animation, and all I know is that it makes me feel disappointed in the design or designer of that product.

Now, I don’t believe that is because I am some sort of weird button elitist, but instead I think it is because that is how powerful good user experience is. I believe that when we come into contact with user experience that is so over the top, and so amazing (as the buttons that inset are, for some reason) then we literally feel like all things should be that awesome. Of course, I wouldn’t judge an entire product because some buttons don’t press down, but that is a big part of how I feel in that given moment going to press that button.

There are tons of outside factors that influence how we feel on a website at any given time, and we need to do all we can to make sure that website presents itself in such a way that we curb all those outside influences into not being as apparent as the inner-influences of our UX is. In general, always think of UX as an umbrella that houses all the points that make up your product’s experience, in the now, in the future (though that’s some strategy), and in the past.

When everyone decided that true beauty online meant a lot, it really took a lot of us by the reigns (horses again, I know), but it actually did. We all took notice, we all started to become obsessed with these products that were designed with these amazing little UI facets that sort of have become overly worn by now. jQuery has had an effect, responsive media queries in CSS have had an effect, so too has the actual design.

It has been argued time and time again, based on all this talk regarding UX and Interaction, is how someone feels on a 2D website actually important at all? Well, if you are trying to get conversions it is; if you are trying to get people to be fascinated by your product or blog it is; if you are trying to get people to understand you it is; if you are trying to get people to listen to you it is; if you are trying to get people to spread your message it is; if you are trying to get people to do pretty much anything then yes, it is very important.

I’m sure you can tell that yourselves, but the reason we often have this seemingly unnecessary debate is that designers who are in one field really don’t know how to define themselves. And for good reason. Designers often end up doing a number of different jobs within the design realm, and that is why it is actually even more important to find someone who knows exactly what they do best and how they fit into the team – unless of course you are looking for a jack of all trades.

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.
