What Our Clients Say

This is the best team I've found. I've dealt with many JavaScript/HTML programmers before, they usually do a mediocre job. But this team did high quality scripting, and was very knowledgeable on the subject. I will definitely contract again in the near future for all my Javascript/HTML needs.

Is Node.JS better than PHP?

The web is a complex maze with a labyrinth of never-ending technologies, with each one of it claiming to be better than the other, which, we understand, cannot be discussed in a single blog. However, we have covered the differences between Node.js and PHP in this post for you to make an informed decision on the choice of back-end technology. Please note that understanding this concept may require prior knowledge in basic web technologies such as HTML, JavaScript, Node.js and PHP. There are scores of useful learning tutorials available online for the same purpose. Node.js and its purpose One thing to remember here is that Node.js isn’t a web server. Node.js, unlike Apache, does not do much on its own and work like it. There isn’t any config file to initialize settings in your programs.  Node.js uses event-driven, non-blocking I/O to stay efficient and lightweight in the face of DIRT (Data-Intensive Real-Time) applications that run in several distributed environments or devices. You have to write an HTTP server (using built-in libraries) if you want to implement an HTTP server. Node.js, being a JS runtime, is an alternate method to execute code on the computer. What can PHP do?  PHP, an alternative to ASP, is an interpreted programming language typically run on UNIX-based and Linux-based servers, and is built to run Windows Servers using an installed interpreter. PHP is used for accessing DBs and server-side form. Due to this feature, it can offer better processing for eCommerce sites. PHP code, like ASP, is included within the body section of the HTML page. Node.js vs PHP  No, it isn’t JS syntax that makes Node.js better than PHP, but rather its simple, understandable code. As you may know, there are several ways to build a Web App in PHP. The following is the syntax used by Node.js and PHP. Both PHP as well as Node.js have access to the command line interface through $ php -i and $ node.  Syntax for printing a statement: The below code prints ‘Hello Infinijith’ in PHP: echo 'Hello Infinijith ';  The below command in Node.js gives the same phrase as output: console.log('Hello Infinijith ');  ‘For’ loop syntax: This is how the ‘for’ loop in PHP look like:  for ($i = 1; $i <= 10; $i++) { echo $i; } The above codes are quite similar to that of Node.js: for (var i = 0; i <= 10; i++) { console.log(i); } An array syntax: This is how one creates an array in PHP: $users = array( array('name' => 'jana', 'id' => 10), array('name' => 'jerin', 'id' => 74) ); An array in Node.js will look like: var users = [ { name: 'jana', id: 2720 }, { name: 'jerin', id: 98 } ] Development Tools  Both Node.js as well as PHP has a wide array of editors, debuggers, IDEs, validators and other tools.  Node.js comes with a tool - the Node Package Manager, or NPM, which lets you set configuration variables, install and run dependencies, define scripts and many more. PHP’s Composer project, though better than Node.js in some aspects, doesn’t feature NPM, and contains a smaller active repository. PHP developers will want to install Node.js at some stage, but not vice-versa.  Both Node.js and PHP are functional languages with a pinch of OOP added to PHP later. 1. Performance: Though PHP doesn’t lag that much behind Node.js in terms of speed, Node.js, all said and done, is usually better.  2. Dependencies:  Node.js requires no dependencies, but its frameworks, such as Express, which performs the work instead. Express, a simple and minimalistic Node.js framework, offers the developers much freedom, as they can use various modules to build the app. Also, because of its flexible nature, it is best suited for large-scale apps that are planned to be extended and need long-term support. PHP runs server-side applications in a request/response cycle, routed via a web server, and the PHP interpreter usually processes the code. 3. Interpreter: Node.js is better and smaller than the PHP interpreter. It is not legacy language support dependant and there has been a lot of investment that went into V8 performance made by Google. Environments: PHP is a server-side development language and rarely outstretches itself. With Node.js, JavaScript is no longer restricted as it can be run anywhere —on the server, desktop, on the browser and embedded systems too. 4. Newer code and latest features enhance Node.js capabilities: Node.js has the advantage of new plugins, built with the newest approaches including express.js, and features, which PHP lacks, though there are several open-source PHP files. Who would want to use old plugins or lose precious time copying retro code anyways? Node.js keeps a single thread for your code and only has a single CPU with a single core. In terms of multiple computations on a multi-core server, there is some work that still remains to be done by the Node core team in cluster module form. Several Node.js server instances can also be run quite easily behind. PHP, by nature, is not single-threaded. Node apps, unlike PHP, run superbly over extended periods of time.  To sum up, Node.js is great for apps having several concurrent connections and each request requires only limited CPU cycles, as it blocks the event loop when a function is executed.

How to Secure Your Code?

The importance of a secure code has never been important today than ever before. Thus, it begs the question: why don't programmers write more secure code?  From the benefits that range from security and safety of confidential information, sound market reputation, to the risks including lawsuits, poor brand image, security code isn’t just about preventing vulnerabilities. The professionals at the Software Engineering Institute of Carnegie Mellon University came up with ten secure coding practises. As simple as it may sound, these are quite effective to secure your hard worked code: 1. Validate input: This you should do from untrusted data sources. Input validation, if properly done, can get rid of most software vulnerabilities. Be wary of most external data sources such as network interfaces, command line arguments, user controlled files and environmental variables. 2. Heed compiler warnings: Code compiling should be done with the highest warning level for the compiler; remove warning with code modification. The additional security flaws should be detected and eliminated with static and dynamic analysis tools. 3. Design & Architect for security policies: Go for software architecture and design your software to enforce and execute security policies. For instance, if your system is designed for different privileges at various times, you should consider dividing it into separate intercommunicating subsystems, each provided with a suitable privilege set. 4. A minimalist approach: Complex designs are likely to increase their error made in the configuration, implementation and use. Further, if you have a robust security mechanism, you needn’t worry about the assurance level. 5. Default deny: The access decisions should be permission-based instead of exclusion-based. This implies that, access, by default, is denied and the conditions, identified by the protection scheme, grants access to permission. 6. Stick to the principle of least privilege: Every process should entail with the least set of privileges needed to finish the job. Any elevated permission must only be accessed for the minimal amount of time needed to finish the privileged task. This can thwart any chances an attacker has to implement arbitrary code with elevated privileges. 7. Clean up data sent to other systems: Clean up and sanitize all data that is passed to complex systems including commercial off-the-shelf (COTS) components, relational databases and command shells. Attackers can invoke functionalities left unused of in these components via the use of command, SQL or several other injection attacks. And we know quite well that this isn’t essentially an input validation issue as the complex subsystem that is being invoked has no understanding of the context in which a specific call is made. As the calling process has a fair understanding of the context, it can sanitize and clean up the data before the subsystem is invoked by it. 8. Practice deep level defence: Adopt multi-layered defensive strategies; therefore, if one layer is not good enough, another layer of defence should serve as a citadel against exploitable vulnerabilities and reduce the effects of a potential exploit. For instance, a combination of secure runtime environments and secure programming methods should likely reduce the probability of the vulnerabilities found in the code level at deployment time could be exploited in the operational environments. 9. Use efficient QA techniques: Effective QA techniques can be useful for eliminating and identifying vulnerabilities. Penetrating testing, source code audits and Fuzz testing should be included as part of an effective QA program.  Secure reviews, if done independently, can result in more secure systems, because this can bring in an autonomous perspective; for instance, in determining and fixing invalid assumptions. 10. Deploy a sound and secure coding standard: Stick to a secure coding method. Create and/or apply a secure coding standard for your intended development platform and language.

Why Unit Testing to be Automated?

An automated unit test suite gives you a number of unique advantages in comparison to other testing strategies; let us take a quick look at some of the possible reasons why unit testing is to be automated: Automated unit testing fixes issues effectively as early as it can, long before the customer gets to use the software, and even before the QA team eliminates them. Most issues in new code are uncovered before now the developers/coders check code into source control. An automated unit test suite keeps watch over the code in two dimensions: space and time. In time dimension, it ensures that code written works now as well as in the future: With respect to the space dimension, the unit test that you write for some other feature guarantees the new code doesn’t infringe upon them; similarly it ensures that the coding done for other features doesn’t adversely impact the code written for this feature. Refactoring a code is altering some code without affecting its behaviour, whilst at the same time integrating new features to the software. Automated unit testing should be set up before refactoring or cleaning up the current code to achieve a clean code structure. When you run the unit tests applying the fixes, they will uncover unwanted side-effects. Releasing quick fixes is neither the solution, nor is publishing hotfixes – only an automated unit test can reduce such things, whilst without causing new problems. Automated unit testing can improve the project’s truck factor, nothing but the number of coders that if, supposing, hit by a truck would bring the project to a standstill. By improving the truck factor of the project, the developer would find it easier to take over and work on a piece of code he/she is not thoroughly familiar with. Remember if your project’s truck factor is ‘1’, then it is under higher risk. Last but not least, automated unit test brings down the need for a project’s manual testing. Though some manual testing will be required, running an automated unit testing is not only cost-effective but critical to perform the mundane testing, while the QA team can deal with the hard-to-find bugs. The combined effects of the benefits discussed above will transform the area of software engineering to be more repeatable and predictable, similar to an engineering discipline, while not putting the ‘art’ in design and coding phases completely out of context. What automated unit testing can do, at best, is to remove the shortcomings of the ad-hoc approach in software development which is the major reason for several problems that confront software projects. Importance of Writing Unit Tests Unit testing, a key area of agile software development process, is excellent for designing robust software, thereby maintaining code and eliminating the glitches in code units. The QA team should never accept any build for verification in the case of any of the failure of the unit tests. This, when made into a standard process, can help catch defects in the early project development cycle, saving valuable time. Takeaways: Testing can be conducted right at the beginning phase of the software development lifecycle. Bug fixing in unit testing can solve several other issues occurring in the testing and later development cycle. Cost involved in fixing a defect and the number of bugs is lower than of acceptance or system testing. Code coverage can be effectively measured. Code completeness can be achieved running unit tests. Robust design and developers, as coders, write test cases only by taking in the specifications first. Easy to identify who disrupted the build. Shortened development time due to reduced defect count How will you write good unit tests? A unit test should be written for the verification of a single unit of code and not the integration. Smaller chunks and isolated unit tests with well defined naming would render it easily maintainable and simple to write. If one part of the software is changed, it shouldn’t affect the unit test if those are small and isolated and developed for a particular unit of code. It should run fast and the unit test must be reusable. Myths and Truths: 1. Myth: Writing code with unit test cases is time consuming      Truth: Saves up development time , as a matter of fact. 2. Myth: Unit testing will find every single bug       Truth: It is aimed at building robust software component having less number of defects in the later phases of SDLC. 3. Myth: 100 percent code coverage means 100 percent test coverage      Truth: No guarantee for error-free code How unit testing improves manageability? Unit testing can help managers control and manage projects better. Functional managers and project managers are focussed on the core activities of the developers. Unit testing can enhance management in a gamut of areas such as reporting and visibility, control and course correction, speed and efficiency, predictability and planning, and customer satisfaction. How automated testing can help? Automated testing is an excellent way to check if the code is functional and continues to do so as intended. Here are specific objectives that must be met: The developer should be able to run the collective efforts of all the developer’s tests. The CI (continuous integration) server must run the complete range of tests sans any manual intervention. The test outcome must be iterative and unambiguous. The primary objective is a range of automated unit tests that help any coder to verify that their current set of changes don’t disrupt existing code under test, thereby eliminating undesirable or accidental outcomes. The second objective is vital in that the CI server can run these tests integrated as part of the thorough and full build cycle, thereby allowing it to verify the efficiency of the system. If you’re a developer you can run the complete automated test suite with zero configurations or setups. The third objective demands the tests be correct, consistent and clear. This means whether a change in the code necessities the tests were through before or if the tests will prove successful if tests are re-run. The Bottom Line Unit testing requires proper execution and consistency. Software projects are quite effective at offering the correct solution in a managed and predictable way. Three objectives to bear in mind when you begin to write your unit tests: Readability – Writing test code that communicates for itself and simple to understand Maintainability–Writing test code that are consistent over time and robust Automation– Writing test code that need zero to little configuration and setup
