Software Designs Anti-Patterns That You Need To Know About!

Software Designs

There is no denying that good and efficient software design is important for making a scalable software system.

We know that developing software is no easy feat; so a good design gives a proper structure and lets you move in a proper direction. The approaches driven by design are quite effective, but there are chances when you understate a project by using some counterproductive techniques or anti-patterns.

But what is an anti-pattern? According to Wikipedia, it is a solution a problem that is ineffective and comes with the risks of being counterproductive.

So, if you are designing software, here are the anti-patterns that you need to know about—

Software designs

Making Your In-House Generic Framework

There are many developers who want to create their own build and make a framework from scratch. Some of them even make libraries using threading, scheduling, and data structures, while some start to use hashing and more.

But do you really think that you will do a better job than the one who is already working in the top-notch and high-end technologies? The best approach is to take help from a professional and avoid this anti-pattern.

Usage Of Numerous Instance Variable In Java

One of the anti-patterns that are used by the software designers is the usage of some instance variables. But what happens when you follow this approach?

Your every variable will lack unit testing from the core.

To avoid this anti-pattern, make sure that you use less instance variables so that each one of them can be tested individually.

Software Designs

Introduction of The Blob

The Blob occurs during a software design part when an object with a massive share of tasks tries to execute the simple processes.

Whenever you are designing software, make sure that there are no blobs in it. Instead, refactor the entire process and distribute the changes by isolating its overall effect.

Availability Of Dead Code

As you start designing the code, there are instances when the forgotten design parts, i.e. dead code are left in it.

This code starts to accumulate and then leads to becoming dead code. To prevent the dead code, use the refactoring procedure that will eliminate the code and will give you a highly optimized structure.

Bottom Line

Whether you are going for a website designing or developing one, make sure you avoid the above anti-patterns. You can also use the tools like SiteSonic that allow you to launch a hassle free website will ready to use templates and more.

Content Security Policy (CSP) Explained

Content security policy

Content Security Policy is a standard of computer security that came into existence for preventing the cross-site scripting or XSS, code injection attacks and click-jacking. It is an added security layer that assists in detecting and mitigating the several attacks types. The use of attacks is for everything that is from the theft of data to the defacement of the site to the malware distribution.

Content Security Policy

Content security policy is the candidate recommendation of W3C which is a group working on the security of web application. CSP offers the standard method for the owners of the website for declaring the content origins that are approved.

Another aspect of CSP is a way for selectively specifying that which content needs to be loaded in the applications of a web. One can do this with the use of hashes, nonces and whitelisting.

How does Content Security Policy work?

The specifying of a Content Security Policy is workable through the website of the HTTP response header by the developer. A browser of a web that supports the content security policy like Firefox, Chrome is something that leads to parsing the information.

The noteworthy element is an approach that is whitelist that includes the instructions such as particular domains, hashes, nonces, and inline scripts that needs to be present and valid for the loading of content.

What kinds of Web Application Vulnerabilities can Customer Security Policy Prevent?

Content Security Policy can efficiently prevent the vulnerabilities like cross-site, issues of mixed content security, click-jacking, the downgrading of protocol and any other form of injection of code. Thus, it is the result of content injection that is not trustworthy into the resource that is trustworthy.

Here are the examples of methods that are different for implementing the Content Security Policy in the web applications:

Domains whitelisting

It is an instance of whitelisting that allow inline scripts and loading of the scripts from Content-Security-Policy: script-src ‘self’ https://www.netsparker.com.

Use of hashes

The activation is through the use of nonce-$random_value in the header response of HTTP. See below:

Content-Security-Policy: script-src ‘self’ ‘nonce-bmV0c3BhcmtlciBydWxlcyA7KQ==’

Certainly, it is vital that the nonce is strong with the cryptographically secure functionality for ensuring as it is not predictable.

Hashes

Furthermore, CSP is configurable for loading resources if they match the defining hashes. It is maybe not probable for executing the resources easily and for setting such as the use of the following header of CSP is usable also:

Content-Security-Policy: script-src ‘self’ ‘sha256-78iKLlw3hSqddlf6qm/PGs1MvBzpvIEWioaoNxXIZwk=’

Put it all together

Hence, Content Security Policy is becoming one of the well-known policies that helps in removing the susceptibilities of cross-site. It helps the developers in ensuring that there are no injection attacks for the website. Therefore, if you intend to integrate the policy, then don’t wait.

 

Everything You Need To Know About System Programming

System Programming Language

To understand system programming, we must first understand what exactly a system is?  System software entails a platform for other software, and it is of the type that includes system software and application software

A few examples of system software include computational science software, game engines, industrial automation, operating systems and software as service applications. Moreover, system software comprises of the operating system (OS) programs and services, including settings and applications. It consists of device drivers that can run basic computer hardware and peripherals.

However, if you work with development, here is how system programming can help-

System Programming Language


The Importance of System Programming

System programming lays the foundation for a computer application development and keeps changing itself to make way for computer hardware. If you need to work with the system program, you need to have some amount of hardware knowledge.

System Programming Language

Any software is written in a low-level programming language capable of operating with efficiency in a resource environment. This low-level language allows direct control over the memory access and also permits the program to be written in an assembly language. Most of the program and software are written in C, C+ and C#.

System Programming Language

Computer System Software Development

System programming eventually leads to the development of computer system software. The latter is for controlling and managing the computer programs completely. The low-level codes are extremely close to the hardware level and account for memory applications and registers.

The system software synchronizes data transfer over different components and also takes care of linking, compiling, starting and stopping programs, reading from the files as well as writing to the files.

Issues and Drawbacks

The system programming has more software engineering issues than low-level performance language. Whether you are a developing an application or a program, the chances are that you might face issues when you are working on it.

We cannot say that it is a low-level language, but functional languages like OCaml and Haskell depend upon the systems.

In summary

So, irrespective of what you are developing, it is important to understand the concept. It is also essential that you have clarity of the programming language design. It also opens the horizons of designing the system around the machine or vice versa.

However, you can also turn to SiteSonic as it allows you to launch a hassle-free website with free templates and more.

Front End Developer? Here Is How To Be The ‘Best’ One!

Front End Developer

Have you ever looked at a website and thought how did it actually happen? Or have you just wondered, how did the design came up; what made the buttons clickable or will I ever able to do this?

Well, there is no denying that the world of front-end development is growing every day. There are days when you doubt that if you could use a plugin or code. If this situation seems familiar to you, here is how you can become a better and best developer.

Front End Developer

Get Experience with CSS Preprocessors

A Website doesn’t work without CSS.

Preprocessors are known as the element that speeds up your CSS coding. It adds a bit of extra functionality to your cascading style sheets and makes them easier to work with.

These processors process your entire code before you send it to be live on the web. The two most famous preprocessors that you can use are-LESS and SASS.

Code Skills

Did you know that HTML and CSS are the building blocks of coding? There is no way around it. But when we say about code, the developers focus on maintaining optimum code quality. However, if the site will not work, it will not matter, if your code is clean or not.

So, if you want to be a good front developer, don’t write code. We are not saying that leave the file blank. Instead, write an HTML file with no CSS or JS in it.

Front End Developer

Learn Cross-Browser Development

Modern browsers are known to display almost every type of website. But the main issues lie in their interpretation of the code.

As the best front-end developer, you have to ensure that your browsers work seamlessly with all the web standards.

Enhance Your Communication Skills

Developers are known to sit behind their computers for regular hours. They code all day and don’t even prefer to interact.

However, before you code, the best approach is to work out with other developers, designers, and testers. Proper communication will not only get you contacts but will also allow you to make the most of your skills.

Bottom Line

Becoming best at front-end development is no easy feat, but you can follow the above tips and take the lead in the process. However, if you are looking to make an excellent website in no time, turn to tools like SiteSonic. With the free templates, editing features and more, it allows you to launch a hassle-free website.

How To Design An Interactive Website Through Scalable Vector Graphics

SVG's

So, what do you do when it comes to adding images to a website?

It’s simple! You will either choose a raster or a vector. A raster graphic is the one that has a set solution and is made up of pixels. While a vector image (scalable vector graphics) has their points, lines, and shapes.

They are commonly known as SVG’s and are an XML based graphic format scriptable, independent and animatable.

If you are want to develop your site responsive as well as interactive, nothing can beat the versatility of SVG’s.

Here is how you can design a website with them-

Create Graphs and Charts

With scalable vector graphics, you can create charts, graphs and display your data through them. SVG’s can be used for any form of data, and are also perfect for impressing your audience.

Morph Various Shapes

Shape Morphing means animating the SVG images using Cascading Style Sheets.  All you need is some code skills, and you can morph one object into another. Moreover, it also gives you a property that can be used to define how the starting and ending points will move and perform.

Scalable Vector Graphics

Draw The Lines To Explain A Context

Lines is one of the powerful mediums in SVG’s as they are scalable, functional, and can be used to illustrate diagrams and more.

Consider Making SVG Icons

Icons are universally understood, and websites all over the world make full use of them. Although the icons are built into the browsers, you can implement SVG icon and enhance its appeal in no time.

Moreover, the SVG icons have good control of CSS and can also match the size of content that is published there.

Animate The Interfaces and Connect Various Processes

Animation of the interfaces is one the easiest ways to make your site interactive as the animations let our brains to connect with the processes easily.

However, by animations, we don’t mean to move every graphic. Instead just animate the load screen icon so that the user knows that your website is loading.

The Bottom Line:

The best part about SVG is that they are equipped with own coordinate system and use their own points to recreate the vector images. So if you are designing a website, use scalable vector graphics or just head to tools like SiteSonic that offer you a free template, editing options and more to launch a website.

5 Tips To Show Your Code On Screen

Code on screen

Are you not able to decipher the code on screen? Well, whether you are building an application or getting it developed, a developer will eventually show you some code.

The display of code includes showcasing different commands on the programming terminal. There are chances that the viewer will sit at a distance, the viewing conditions are different or don’t know about the language. Irrespective of what the viewing scenario is, here is how you can show your code on the screen.

Code on screen

Use A Simple Syntax Highlighting Style

If you want the viewer to get an understanding of the code, use a highlighting syntax style that will let him recognize at one go.

To make the code more viewable, use black text on a bright background. But make sure that you don’t use dark fonts on a dark backdrop, bright shades on white background and dark on a dark background.

After all, it is better not having a highlight than having a good one.

Highlight The Current Code

The code is a collection of parameters and can wobble a person who has little or no understanding of same.

One of the best approaches to show code highlights the line that is being displayed. And in case, if you are live coding on screen, this approach will help you to keep viewers on the track.

Consider The Code Presentation As A Presentation

When you are presenting a code, you will have to prepare for a proper presentation. You cannot make slides or using different media, but make sure you prepare well enough with your color schemes, font size, and more.

Use A Block Cursor

To enhance the visibility of code, use a block cursor with a low blink rate. So, whether you are refactoring during the code or not, a block cursor will keep you and the viewer on the same page.

Code on screen

Use The Line Numbers

Every programming terminal comes with the line numbers. You can use them and keep the viewers along with you, as show your code on screen.

In case, if they lose the track, all you need to tell them is a line number to get back.

But make sure you remember that the code viewing conditions are not the same when you are viewing alone or looking at someone’s code. However, if you don’t prefer to code, you can use the various tools such as SiteSonic and use their free templates to launch a hassle-free website.

System Design Principles That You Need To Learn

System Design Principles

Before we head on to the principles, what is System Design?

According to Wikipedia– it is known as the process of defining the modules, data, interfaces, and architecture of a system to cater the specified requirements of a product.

These systems keep the entire product consistent, enhance the workflow efficiency, and also improve the user experience with the proven patterns. And if you are a product engineer, your main role is to build and design products.

However, when you design the products, there are various design problems and solutions to them, which you can use and implement as an end product. If you are also pondering over them, read here:

SystemDesign

How Can You Make A Feature Robust and Reliable?

When you are making a design, you should choose a specific feature. Once the feature is designed, you need to focus on making it reliable and robust.

To make it excellent, you need to learn about the set of people and their scenarios that are going to use it.

What Is The First Iteration?

When it comes to system design principles, the iterations occur when you are building a system from scratch or the final product is large in size. The repetitive iterations help you to solve the issues so that the end product is excellent.

System design principle

System Designs Need To Integrate Accessibility

Whenever you design a product, you should apply the accessibility design constraints. For example- if your users are screen readers, you can use alt-text for it. However, there are chances that the users may have sightedness issues; you can use resized type for it.

These features allow you to integrate accessibility so that users can use product features with ease.

 What Is The Captured Data?

There is some amount of data capturing required, which includes- action logs, event logs, failures, metrics, and anomalies.

However, when it comes to the data usage, you can store the data in structure as it makes the process easy and convenient.

Scale A System Design Properly

To scale the system design, start with using the “defined primitives”. The primitives include text style, color schemes, grids, and more. You can build your system with these primitives and ensure proper consistency in the process. But you need to be flexible and make a product that is platform friendly.

Along with the system design principles, you can use other tools like SiteSonic that offers you auto-sync content feature, lets you explore many free templates, and also allows you to launch a hassle-free website.

Tips for Fixing Website Bloat and Readability Problem

Fixing Website

We cannot deny that websites downtime issues cost your business hundred and thousand dollars per minute. Are you also facing issues like- website is not available, error 404, URL not found? Or you website simply does not load!

Well, these issues occur when your website is bloated, has readability issues, and is not maintained properly.

Bloating occurs when the website has unnecessary pages in the Index and is costing search engine more processing time than required. The readability issues come when the content is irrelevant and hard to read.

If you also have a hard time dealing, here is how to fix them:

Fixing website readability

Lets Users Use Their Preferred Settings

The developer should create a settings page that can allow users to use their preferred font, font color, line dimensions and position. Moreover, allow the settings for the HTML tags that are relevant for the text.

Use Robots.txt File

For fixing website bloat issues, block the URL parameters in the “robots.txt” file. This file does not let search engine to crawl a page, but it will still index the page if it is linked to the internal or external website.

Fixing website bloat

Get Rid Of Radical Components

The radical components include extra CSS and JavaScript.

Well, it is impossible to make an audio, video, or a chat application without JavaScript, so it does not come as a possible solution. However, we can use Semantic HTML instead of CSS, but it cannot provide the functionalities required for modern usage.

We cannot get rid of JS and CSS, but you can definitely minify the unessential elements.

Fix The Bloat With Meta Robots

The Meta Robot method can be done if it is implemented from a server level across multiple pages.

These robots also remove the URL that has the parameters caused by the product filters, internal search functions, and navigations. Moreover, Google agents can see the parameters that can negatively impact your search campaigns.

Use Canonical Tags

Self-referencing canonicalization is also considered as the best practice to resolve these issues.

Just add a canonical tag to the header of the unnecessary product and URL’s, and Google will understand which page to index and which not to. However, you need to remember that canonical tag is just a directive.

So, whether you are fixing the issues or building a new website, you can also use tools like SiteSonic that gives you free templates, allows to auto-sync content, and launch the website effortlessly.
