A Quick Guide to Developer’s Software Security Checklist

Developer’s Software Security Checklist

Modern software development involves multiple distributed teams with remote developers in different networks. This makes remote networks vulnerable to cyberattacks. A software security checklist is crucial to secure remote developers from potential cyber risks.

But why invest in a software security checklist?

Software cybersecurity is not just about installing an antivirus on a developer’s system anymore. The advent of generative AI for code generation has opened a new potential threat. AI-driven software development can expose sensitive information, and Samsung’s ban on ChatGPT is one example.

Besides AI-driven software development, ensuring robust code is also crucial for developers. One vulnerability can impact your operations. As stated by Deloitte, 48.8% of C-suite executives anticipate higher cybersecurity attacks on their systems. Increased software security threats require an extensive strategy. This article provides a definite software security checklist for your projects.

Why Do You Need a Software Security Checklist?

A software security checklist is like a guideline that ensures you check all the right boxes for better website protection against cybersecurity. A security checklist offers a structured approach to mitigating risks and ensuring cost-effective data protection.

It helps identify vulnerabilities in your website, acts as a roadmap for risk mitigation, ensures compliance with global data protection standards, and prevents cyber-attacks. By following a checklist, you can develop a more secure website while maintaining data protection standards and guidelines.

A Security Checklist for Web Developers:

A software security checklist lists the necessary steps and measures to protect websites from cyber threats.

1. Choose a Secure Web Host

Web developers must opt for secure hosting services to ensure data protection and compliance with essential security guidelines. A hosting service allows you to store website files and resources. There are many different types of hosting services, but choosing the right one can make or break a website’s security. Some types of hosting you can choose from are: 

●  Shared hosting: This is a type of hosting where many websites share the same server for hosting resources. Shared hosting is not an ideal choice if you want to secure a website because the vulnerability of any site sharing your resources can affect security.

●   Virtual private server (VPS) hosting is one of the most secure options for any web developer because of the dedicated server. VPS hosting offers a setup where each instance is independent and does not have the impact of any other website.

●    Cloud hosting: Cloud hosting distributes resources and data of your website across multiple virtual servers, ensuring there is no disruption in case of a cyberattack. It offers a failsafe option among all the other hosting options.

You need to choose the type of hosting suitable to your software security goals as a web developer.

2. Secure Web Apps & Software Applications With Digital Certificates

Digital certificates are your guardians against attacks like a man in the middle (MITM), where attackers target data transitioning between server and browser. SSL/TLS  certificates help you secure a website through cryptographic encryption, where the data between the browser and server is scrambled. Such data is unreadable for hackers, making it secure.

This is a crucial aspect of your software security checklist because it allows you to secure multiple domains and apps. For example, you can choose a wildcard SSL certificate to secure various subdomains with a single certificate. Similarly, multi-domain certificates help secure several websites at the same time. 

While choosing a digital certificate for your website, ensure it has a SHA256-like robust encryption algorithm. Also, check if the certificate authority is trustworthy with a proven track record.

You can purchase an SSL certificate from CA by submitting a certificate signing request (CSR) containing critical details regarding your organization. CA will verify it and issue a certificate you can install to secure a website.

3. Securing Software Applications

Web developers must consider different attack strategies that hackers can use while designing their applications. Considering backdoors and vulnerabilities that hackers can exploit, developers can create codes with better traceability.

If your application has third-party integrations or open-source services, scan for vulnerabilities. Because many open-source services have vulnerabilities that can expose your software applications.

4. Encrypt All Connections and Secure User Logins

Securing the connections to your website requires strong encryption. Use SSL/TLS certification to secure all the connections for your website. To secure user logins, you can use authentication policies that mandate verification of users beyond passwords.

For example, Google uses two-factor authentication for users to access their apps like Gmail, and YouTube. Similarly, you can design your login page to include such an approach to secure user logins.

5. Use a Web Application Firewall (WAF).

Web application firewalls filter malicious traffic to your website. WAF allows your website to secure sensitive data from malicious traffic. At the same time, it helps your website comply with search engine ranking guidelines.

For example, Google penalizes websites with spammy traffic and content. So, as a web developer, you must ensure malicious traffic from unknown sources does not impact your website’s search engine rankings.

6. Keep Your Database Secure

Ensuring higher database security is indeed a fundamental approach to securing websites. Regular system vulnerability scans and penetration tests for databases can help mitigate the risks of data leakages.

Having a data recovery plan with automatic backups can significantly reduce the time to recovery in case of any mishap.

7. Try to Hack Yourself

Securing your websites and software applications and developing a thorough security incident response plan are important. Conduct security assessments by attempting to hack into your own websites. Target the websites in controlled environments with specific malware attacks to evaluate how resilient your system is against attacks and identify vulnerabilities.

Key takeaways

Securing your websites and software applications requires a planned effort. A software security checklist ensures you have every security measure organized in a step-by-step process to ensure enhanced security.

It allows you to assess systems, monitor errors, and identify vulnerabilities. Based on the identified issues, you can design security measures and secure websites. You can use the above-given checklist to secure sites and improve the user experience. However, what to include and omit from the checklist depends on your software security needs.

Beginner’s Guide to Building GraphQL APIs with ASP.Net Core

Beginner’s Guide to Building GraphQL APIs

Facebook made GraphQL available as open source in 2015. It is housed at The Linux Foundation and functions as an unbiased, nonpartisan repository for the GraphQL assets and ongoing cooperation. The GraphQL Foundation serves as the completely impartial home for the GraphQL trademark and offers a mechanism for membership dues collection and distribution in support of essential community infrastructure and initiatives.

GraphQL is an enhanced and more flexible query language for APIs than REST. It is now open-sourced and has a large community behind it.

In the last few years, the industry standard for creating web APIs has been restful architecture. However, it has been shown that REST APIs are too inflexible to adjust to the constantly shifting needs of the clients that use them. Employ.Net core developers to integrate and implement dotNet core GraphQl. Let’s now explore what GraphQL is and how to build GraphQL APIs with ASP.NET Core in this blog post.

What is GraphQL?

Facebook created GraphQL, an open-source query language for APIs. Customers may request exactly what they need and nothing more with GraphQL because of its syntax, which allows it to request particular data and provide that data from many sources.

The flexibility of GraphQL is its greatest asset. Suppose you are in a restaurant and would like to order food, but you would prefer a customized dish where you may select the elements you want and don’t want. GraphQL functions similarly to a customized menu, allowing you to select the precise foods and ingredients you desire without having to settle for the house specialty at a restaurant.

With a typical API, you receive whatever information the server chooses to offer you, which can include data that you don’t need right now. By using GraphQL, you may reduce bandwidth usage and enhance the efficiency of your application by only requesting the precise fields that you require.

When To Apply GraphQL?

A query language and runtime for obtaining and modifying data in APIs is called GraphQL. It is advised to use GraphQL when there are requirements such as these:

  • Flexibility of queries: GraphQL allows users to request just the precise data they require, preventing the data overload that frequently happens with conventional RESTful APIs.
  • Decrease in the number of API calls: Often, all the information required for a particular capability or visualization may be found in a single GraphQL call, negating the necessity for additional API calls.
  • Complex data modeling: GraphQL can be a wonderful choice if the system has a complex data model with relationships between various object kinds. Customers can effectively navigate these interactions thanks to it.
  • Modernizing the API without disrupting client apps: You can expand your API by adding new fields and types using GraphQL without interfering with already-running clients. If and when they require the updated data, they merely need to request it.
  • Applications needing multiple sets of data: GraphQL enables you to give each client the precise data they require without having to create versions apart from the API, which is useful if you have different customers, such as web and mobile applications that require distinct sets of data.

Build GraphQL APIs with ASP.Net Core: A Detailed Guide

A strong query language for your API, GraphQL offers a more effective and adaptable substitute for REST. Customers can request exactly the data they need in the format they need. A cross-platform, high-performance framework for creating contemporary, cloud-based, and internet-connected apps is called ASP.Net Core. ASP.Net Core and GraphQL together can be used to build dependable and adaptable APIs.

Here are the steps to Build GraphQL APIs with ASP.Net Core

Step 1: Organizing Your Workspace for Development

You must first set up your development environment before you can begin using ASP.Net Core to create GraphQL APIs. Make that your computer is running the most recent version of the.NET Core SDK. You will also require a coding editor, like Visual Studio coding or Visual Studio.

Step 2: Starting a New Project for ASP.Net Core

Make a new ASP.Net Core project to get started. Visual Studio or the.NET Core CLI can be used for this. To create a project structure scaffold, select a Web API template. The structure and dependencies needed to create APIs are included in this template.

Step 3: Installing NuGet Packages That Are Needed

It is necessary to install multiple NuGet packages to incorporate GraphQL into your ASP.Net Core project. GraphQL, GraphQL.Server.Transports.AspNetCore, and GraphQL.Server. Ui.Playgrounds are some of these packages. These libraries offer a UI for testing your GraphQL queries along with the server transports and fundamental functionality required for GraphQL.

Step 4: Configuring Types and Schemas in GraphQL

Schemas are used by GraphQL to specify the organization of the data that is made accessible via the API. Make a new folder for files related to GraphQL in your project. Define your GraphQL types and schema inside this folder. Your data is shaped by types, and the schema specifies the queries and changes that can be used.

Step 5: Formulating Inquiries and Variants

While mutations are used to change data, queries are used to retrieve it. In the schema, specify your queries and changes. Each mutation and query should correspond to a certain resolver technique. Classes called resolvers are equipped with the functionality needed to retrieve or alter data.

Step 6: Setting Up Dependency Injection

Dependency injection is a key component of ASP.Net Core’s dependency management system. Set up the services in the Startup.cs file that GraphQL needs. This involves establishing middleware to handle GraphQL requests, adding GraphQL services, and setting up the schema.

Step 7: GraphQL Middleware Configuration

The request pipeline is managed by middleware in ASP.Net Core. To manage incoming GraphQL requests, include the GraphQL middleware in your project. The relevant answers are returned by this middleware after processing the GraphQL queries.

Step 8: Checking the GraphQL API You Use

It’s time to test your GraphQL API now that it’s configured. Utilize resources like as Postman or GraphQL Playground to communicate changes and queries to your API. Check to make sure your API is functioning as intended and that the responses correspond to the expected output.

Step 9: Securing Your GraphQL API

Any API must have security measures in place, including GraphQL API security. Give your GraphQL API authorization and authentication to safeguard critical data. For API endpoint security, leverage the integrated permission and authentication features of ASP.Net Core.

Step 10: Developing and Implementing Your API

After your GraphQL API is secure and operational, concentrate on optimization. To boost performance, use batching, pagination, and caching. Lastly, make sure your API is reachable by customers by deploying it to a cloud provider such as Azure or AWS.

Final Thoughts and Conclusion

We learned about how to Build GraphQL APIs with ASP.Net Core in this article, including its key metrics and how flexible it is in comparison to more conventional REST APIs.

In addition, we developed an ASP.NET Core project and used the NuGet libraries to link it with GraphQL. After that, we started the project and observed how to retrieve data using the GraphQL interface.

It’s crucial to emphasize that even with GraphQL’s benefits, it’s always a good idea to Hire ASP.net developers. After all, GraphQL might not be the best option in situations where there isn’t a lot of data and relationships between them.

GraphQL is simply an additional choice when working with large-scale online applications; it is neither better nor worse than conventional REST APIs.

Below are some of the most common ways AI and robotics are being used today to transform factory settings.

Smart Automation

Again, AI-powered systems are embedded with deep learning programs and neural networks that enable them to work optimally with little to no human intervention. This allows human workers to focus their attention on other more important tasks that do require a human touch, while the robots take care of everything else. This allows for numerous factory operations to be automated, which can reduce human error and cycle times, and speed up production processes. 

Quality Control

Consistency is key to success in the manufacturing industry. This means machines and equipment that are consistently working as they should to help produce consistent and high-quality products. This is where AI steps in. 

AI-powered computer systems can monitor input from various factory robots and equipment, keeping an eye out for any anomalies or issues that could impact production. For example, many AI-powered systems in manufacturing settings now use analysis for predictive maintenance, which helps avoid breakdowns and malfunctions that could lead to delays or shutdowns.  

Layout Optimization

The way the factory floor is laid out and organized can also play a role in production output and efficiency. If things are not laid out as optimally as possible, for example, it can make it harder for a worker to do their job. 

AI-powered tools and sensors, however, can analyze layouts and suggest a better plan to improve efficiency and reduce issues with safety, space, and materials. If a short-run project arises, these systems can also suggest a temporary reconfiguration to better suit the needs of the project. 

Even after the factory is set up, sensors can continuously monitor and make suggestions to improve process flow based on how things are running. 

Generative Design

Generative design using AI allows engineers to input a set of requirements for a product, such as the parameters and design goals, and then the AI uses that information to test out hundreds, even thousands, of different iterations until the best option is found. This is something that could normally take months or years for a person to do themselves, but AI can do it much faster, which allows companies to create the most optimally designed product in a shorter amount of time. 

Current Case Studies for AI and Robotics

Already, hundreds of companies around the globe are using AI and robotics to improve manufacturing processes. 

Siemens’ (SIEGY) has adopted Microsoft’s OpenAI Service to harness generative AI design to help a number of industrial companies drive efficiency and innovation across their manufacturing processes.  

DHL is deploying Boston Dynamic’s Stretch Robot to optimize its supply chain, using it to help grab and move packages. 

Rockwell Automation’s Smart Manufacturing software uses AI to equip factories with the insights needed to optimize risk management, quality, productivity, and sustainability. 

Walmart recently built a 1.4 million-square-foot facility in Florida, their first automated distribution center powered by AI supply chain technology from the company, Symbiotic. 

NVIDIA provides a number of AI solutions to the industrial sector, including IGX Origin, a platform that provides predictive maintenance, robotics, and industrial inspection solutions. 

In the United States alone, manufacturing companies have heavily invested in smart automation installations in recent years, including 44,303 robotic units in 2023. These numbers are expected to continue growing as more companies look to these technologies to upgrade their factories and improve efficiencies. 

Challenges to Consider

While smart automation technologies have the power to positively transform the manufacturing industry, using AI and robotics still comes with challenges. The ethical implications of AI are important to consider, for example. 

In any setting where you have human-robot collaborations or human-AI collaborations, it’s necessary to understand the ethical challenges, such as safety, communication, and job displacement. 

While robots are often used to make factory settings safer, if workers do not understand how to properly interact with these systems, it can end up causing more safety problems. This is where thorough training plays an important role. If companies intend to integrate robots, they must first make sure their workers fully understand how to use and interact with these advanced systems. 

For example, many robots have user interfaces that workers can use to access and adjust settings, however, if workers don’t have any programming knowledge, they could struggle without proper training. Additionally, factory robots can also sometimes be controlled using voice commands, but if workers don’t adapt to these voice controls, it will make it difficult for them to work in the same area as the robots.  

Another challenge that can arise is low morale due to fear of job displacement. When integrating AI-powered systems and robots, it’s crucial that companies alleviate these fears by assuring their workers that these systems are meant to help them do their jobs better as opposed to replacing them entirely. 

Cybersecurity Concerns

Another challenge worth noting is potential cybersecurity issues. As processes and systems become more digitally connected and intertwined, it makes them more susceptible to cyberattacks. For example, while rare, industrial robots can be hacked as can other AI-powered systems. 

To avoid these risks, manufacturers must take steps to increase cybersecurity awareness among workers and implement advanced cybersecurity protocols. This means training workers on how to use these systems without putting any sensitive data at risk and even limiting who has access to controls. It also means using device-hardening protocols and end-to-end encryption to protect data. 

Keeping up with the latest software updates and firmware patches is also important to reduce system attacks, as well as conducting regular cybersecurity risk assessments. If manufacturers don’t want to handle this themselves, they can hire vendors who can monitor cybersecurity threats for them and distribute updates and patches as needed.   

Final Thoughts

While there are risks associated with the adoption of any new advanced system, the pros generally outweigh the cons. So long as companies are smart about how they integrate AI and robotic systems, these technologies have the power to lead to greater efficiency and production output. It will also help companies stay competitive in an evolving digital landscape.

How to Leverage Software Development Lifecycle Diagram

Whether for the commercial or games market, software development is a complicated process. With over 26.3 million developers around the world, there are many tried and proven methods that can help make the development process easier. One main methodology is the Software Development Life Cycle (SDLC) which allows development teams to make high-quality software in the quickest time possible. 

As with any proven process, following the various steps can help people avoid mistakes that could delay deployment or create errors in the software. One helping hand that can be useful with the SDLC is the Software Development Lifecycle Diagram (SDLD). Just what are the SDLC and SDLD? And how can using them help ensure that your software is deployed on time and of the highest quality?

What is the Software Development Life Cycle (SDLC)?

As mentioned, the SDLC is a methodology with well-defined processes that allows developers and DevOps teams to create quality software (usually within a short timeframe). To make things easier for developers, the SDLC breaks the development process into six main phases:

  • Requirement analysis.
  • Planning phase.
  • Software design incorporating features like architectural design.
  • Software development.
  • Testing.
  • Deployment.

As well as the six phases outlined above, there are various SDLC models such as the waterfall model, spiral model, iterative model, or the agile model. Developers will utilize different models according to their needs and the type of software they are developing. For example, the model used to develop software for a hosted VoIP service might be different from that used for inventory management software. 

In cases like eCommerce platforms, incorporating eCommerce analytics into the development process can enhance user experience and provide valuable business insights. This flexibility allows developers to choose the most effective approach for the specific requirements of their project.

What is a Software Development Lifecycle Diagram?

A software development lifecycle diagram is simply a pictorial representation of the particular SDLC that may apply to the software you are developing. It breaks the cycle down into the steps you need to take to successfully develop a product and can act as a checklist; complete one step before moving on to the next. 

The stages of your SDLC/SDLD

If you’re developing a new piece of software, there are many things to consider before you even move to designing and coding it. Is the software standalone or will it be added to a suite of existing applications? If so, does it need to fit with an application portfolio management APM system that’s already in place? 

Your starting point is always going to be purpose. What will the software be used for and what are the users’ requirements?

1. Analyze user requirements

Before you even start planning the software, you need to understand what it’s for and what features it needs to have. Is it to solve problems or fulfill wants? You need to get input from all relevant stakeholders and that can include everyone from customers to programmers.

For example, a business may be migrating legacy applications and some of the apps or software may not be compatible with the new system. You will need to be aware of any improvements that need to be made as well as any security risks the software may face. 

2. Planning

Once you know what is required from the software in the previous phase, you can move to creating a detailed plan. In this step, your DevOps team is going to look at various factors such as cost estimates for developing the software and what resources will be required. 

One major consideration at this stage is security. What sort of data will the software be handling, are there any regulatory requirements such as the CCPA, and what vulnerabilities may exist? 

In this stage, it is also crucial to consider the database concepts that will underpin the software, ensuring data integrity, scalability, and performance meet the anticipated needs.

A comprehensive security assessment should be conducted to identify and mitigate potential security risks before proceeding further in the development process. You need to be sure that every base is covered in the planning stage to prevent issues from arising later. 

3. Design phase

Now that you know that the plan is feasible and what resources are needed, you can start designing the software. You should be letting all stakeholders review your design specification to ensure it’s ticking all their boxes and so that they can give you feedback and offer any suggestions as to changes that may be needed. 

It’s essential that you have this feedback – and that you listen to it – as failure to do so could lead to exceeding planned costs or even project failure. If a stakeholder identifies that you are missing something from lead enrichment software, for example, not taking that feedback on board and rectifying any omission could mean the project is doomed. 

Ensuring all necessary features and functionalities are included and aligned with stakeholder requirements is critical for the success of the project.

4. Build it and they shall come

You have a roadmap of the software you are developing so can now move on to the actual building of the product. If your DevOps team is working from the same location, it should be fairly easy to stick to the blueprint and follow any guidelines you have established. If some of the team are working remotely, then you will need to ensure you have good communication tools that will foster collaboration. 

You will need to establish guidelines as to what code style you will use and what practices to follow. Have a set (or variable) naming practice for your files so that every member of your team can write code that is consistent and well-organized and will be easier for you to test during the next stage. 

5. Testing one two

Before you even think about deployment, you need to be sure that everything works as intended. Testing at this stage should also be looking for any defects and any potential security vulnerabilities as well as integration testing. You may operate a test-driven environment and do all your testing in-house or, especially for larger projects, you may choose to have external beta testers.

There are various types of beta testing that can allow you to focus on special features such as headless CMS or test the product’s overall functionality. Testing different aspects of your software is essential as identifying and fixing any problems prior to deployment can save a lot of headaches later. 

6. Ready, steady, go

Once the testing process is complete – and any problems rectified – you’re ready to deploy the software. During the deployment phase, utilizing a cloud computer can be crucial for ensuring the scalability and reliability of the software. This allows for seamless access by end users from various locations, enhancing the overall deployment strategy and user experience

This could be to consumers as a purchasable software product or as part of the apps supporting a business capabilities model. Even with the most rigorous testing, your DevOps team should be monitoring use and any feedback that comes from end users as to whether the product met customer expectations or not. 

The thing to remember here is that while testing may have a small pool of testers, actual deployment will have a pool of thousands of users if not more. In an ideal scenario, your software will be deployed with no problems but the reality is that you will probably expect some issues that are hopefully only minor ones. 

Software development lifecycle security

Security is always going to be a primary concern when developing and deploying software. You need to be aware of the answers to several questions such as ‘What sort of data will the software be handling’ or ‘What is enterprise architecture management and what role will the software play in it?’

With SDLC, and your SDLD, security should not be seen as a separate stage but as an integral part of the process that is involved in every stage through DevSecOps practices. This methodology assesses security throughout the development process and looks at how secure the various features of the software are and how well it can stand up to potential threats once deployed.

These assessments can include tasks such as analysis of the architecture, automated detection, penetration testing, and code review. Your assessments should be part of the integrated development environment (IDE), servers used for the build, and code repositories. You should be looking to integrate DevSecOps into your SDLC in the following ways:

  • Planning analysis: In this stage, you should be identifying any security needs, mitigation plans, and potential threats the software may face.
  • Design. During the design stage, think about what features will meet your security needs. You could utilize threat modeling and a risk analysis of your planned architecture. You could also consider features such as encryption mechanisms and access control. 
  • Development and testing. You should be carrying out code reviews to ensure that any code meets your standards and that the security measures are implemented. During the testing phase, carry out tests such as penetration testing to identify any vulnerabilities. 
  • Deployment. There are automated DevSecOps tools that can help ensure and improve app security. You should also be looking at other factors such as access controls, firewalls, and security settings. 
  • Maintenance. Cybercriminals are constantly looking for new ways to infiltrate software and systems. Cybersecurity experts need to be just as proactive in finding ways to stop attacks. If any new risks or vulnerabilities arise, have your team look at any required updates or patches. 

The takeaway

Every software project is important, whether it’s for a gaming app or a commercial application. Both simple and complex projects should follow the SDLC and SDLD process. Your end goal is always customer satisfaction and to avoid as many errors as possible, especially when it comes to security. 

Having a software development lifecycle diagram to guide you through every development project can ensure that you follow all required steps and adhere to the relevant best practices. You should always be aware of the most common errors and be aiming for consistency from all of your development team. Keep to the plan and you’ll have a quality product and happy customers.

Developing AI-Assisted Software with TensorFlow and Keras

AI-Assisted Software with TensorFlow and Keras

In very simple words, AI-assisted software uses artificial intelligence to perform tasks that normally require human intelligence. You might be wondering what human skills can be replaced with AI, so here is the answer to your questions. AI-assisted software can recognize speech, make decisions really fast, and understand natural language.

From all this, you can guess why it’s such an important innovation. It fundamentally changes how we operate in different fields, making our work smooth and more efficient. AI also improves accuracy and decision-making in various fields. For example, one can apply it in healthcare for diagnosing diseases, in finance for fraud detection, and in customer service for chatbots.

You Main Helpers: TensorFlow and Keras

If you want to dig deeper into the topic, then check out two powerful tools for AI development: TensorFlow and Keras. We’ll talk about them below, but for starters TensorFlow is an open-source platform for machine learning and  Keras is a user-friendly neural networks API that runs on top of TensorFlow. What’s so great about them for developers? These two frameworks make it easier for tech specialists to build and train AI models, which are so helpful.

Getting Started with TensorFlow and Keras

Before you reap all the benefits of these tools, you have to understand how to install them properly. We are not going to leave you alone with it, let us guide through this complicated process. 

1. Install Python

You might not understand what’s the point of this step but it’s very important. Here is why: TensorFlow and Keras are libraries built for Python, which is a programming language commonly used for AI and machine learning. That’s why you can’t use these great tools without installing Python on your computer first. Basically, it is an essential component to run these libraries and write your AI programs.

2. Install pip

The next step is also related to Python. You have to make sure that you have pip on your laptop as it simplifies the process of managing and installing Python packages. Thanks to pip, you can be calm knowing that you have the latest versions of essential packages and all the required dependencies. So, don’t skip this stage even if you feel tempted to do it.

3. Create a Virtual Environment

Unlike the previous necessary step, this one is optional. You can skip it if you want even though we don’t recommend doing it. To give you a deeper insight into this stage, let’s define a virtual environment. In short, it’s a space where you can install Python packages without affecting your system-wide Python setup. Why is this so important? 

Because this helps to manage dependencies and avoid conflicts between different projects. If it sounds too theoretical for you, let’s consider an example. Imagine that you have multiple projects at the same time and each of them requires  different versions of the same library. Virtual environment can come in handy in this case it ensures each of your projects has its own dependencies and versions.

4. Install TensorFlow

Now, let’s move to the most interesting part and the essence of this section, which is installing TensorFlow. Among the benefits of this tool, you get access to its powerful features for building and training machine learning models needed for your software. If you don’t want to handle all the  heavy lifting of complex mathematical computations, then go for this solution. All the experts say that it provides an extensive library of pre-built models and algorithms needed for their professional purposes. 

5. Install Keras

Now it’s time for Keras. This is a high-level neural networks API that runs on top of TensorFlow and simplifies processes. The point of Keras is that it builds and trains neural network models with  an intuitive and user-friendly interface. Obviously, this is one of the main things when it comes to user experience, so you can greatly benefit from Keras, no matter whether you are an experienced developer or a beginner. 

6. Verify the Installation

Verifying the installation ensures that TensorFlow and Keras have been installed correctly and are ready to use. By importing these libraries and checking their versions, you confirm that your setup is complete and functional. This step helps to catch any installation issues early on, ensuring a smooth start to your AI development journey.

Building Your First AI Model with TensorFlow and Keras

You must be scared to even think about such a big task ahead. But trust us, it’s going to be a fun and rewarding journey. And remember, there is only one way to eat an elephant: one bite at a time.

1. Setting Up Your Environment

Logically, you’ll need to set up your environment first. You should check if TensorFlow and Keras are installed properly and ready to use. 

2. Understanding Key Concepts

If you don’t understand basic concepts, you’ll be helpless. So let’s make sure you know what we are talking about. 

– Layers: Layers can be perceived as building blocks of your neural network. To dig deeper into the structure, each layer has neurons (or nodes) that process the input data and pass it along. If it’s still not clear enough, you can think of layers like a conveyor belt in a factory, where each station does something different with the product (your data) as it passes through.

– Neurons: If we continue to expand this metaphor, neurons are the workers at each station on our conveyor belt. As you may guess, their function is to receive input, apply a weight to it, and then pass it through an activation function to produce output.

– Activation Functions: Here is where things become more complicated. These kinds of functions introduce some complexity to our model because it’s their job to decide which neurons to activate based on the input they receive. Common ones are ReLU, sigmoid, and tanh. 

– Training: Please, don’t be fooled by the familiarity of this word because now, this is where the magic happens. Training is when your model learns from the data. It works the following way: you feed the data into the model, it calculates the error (the difference between what it predicted and the actual answer), and then it adjusts its weights to get better. This process is repeated many times (called epochs) until the model performs well enough to be functional.

3. Building the Model

Alright, now let’s end with terms and build our model. As a first step in this exciting process, you need to start by defining the structure of your neural network. And now it must become clear why we mentioned Keras. By using it, you stack layers and specify the type and number of neurons in each layer. If we were to provide a metaphor again, it’s like sketching out a blueprint for a building.

4. Compiling the Model

The next step brings you much closer to a ready software. Here, you have to compile the model so that it’s ready for training. To add details, this is where you specify:

  • the loss function (to measure error)
  • the optimizer (to adjust weights)
  • metrics (to evaluate performance).

5. Training the Model

Now it’s time to train the model you’ve carefully created in the previous steps! You’ll use your dataset, splitting it into training and validation sets. What is happening during training? In simple words, the model adjusts its weights to minimize the loss function. You might think that it’s the end of your developing journey, but it’s not true. There is one more important step left.

6. Evaluating the Model

Finally, you evaluate your model’s performance using test data. Otherwise, you never know if the model generalizes well and performs accurately on new, unseen data. 

Conclusion

AI-assisted software development with TensorFlow and Keras can deeply transform human experiences. This way, we can create intuitive, engaging, and accessible applications that truly resonate with users. As you venture into AI development, remember that you’re making the digital world a more connected and inclusive place. So, dive in with enthusiasm!

How to Optimize CSS and JS to Speed up your site?

Optimize CSS and JS to Speed up your site

Suppose you’ve noticed that your site is taking a bit too long to load. More often than not, the problem lies in its code. Whether it’s Cascading Style Sheets (CSS) or JavaScript (JS), it has to be optimized so the code can be processed faster. 

Doing so will instantly give a boost to your site’s speed and improve its performance as well. Having said that, there are many ways to go about this. 

In this article, we’ll cover most of them so if you want to learn how to optimize CSS and JS for speeding up your site, read on. 

Ways for Optimizing CSS and JS to Give a Boost to Your Site Speed

Optimize CSS and JS to Speed up your site

Below, we’re going to discuss the different ways in detail so you can understand better. An example will also be provided for each one. 

1. Minification

Minification is the process of removing all the unnecessary things from a code without changing its functionality. These things mainly include the characters, whitespaces, and comments.

This reduces the size of your website code and the servers take less time processing it, resulting in faster load speeds. Having said that, you can minify your code manually by removing the aforementioned things. However, the manual process is only recommended when the original code isn’t too long. 

Website codes, whether CSS or JS are usually quite long, and manual minification isn’t suggested for them. This is because there are huge chances of errors and it’ll just take a lot of your time. Therefore, it’s best if you just run your site’s code through a tool like Minifier.org to automate the process. We personally do this as well whenever the need arises. 

To exemplify minification, below are examples for both CSS and JS. It is worth mentioning that we used the said tool to generate these examples. 

CSS Minification Example

Original CSS Code:

/* This is a comment */
body {
    background-color: white;
    font-size: 16px;
}

Minified CSS:

body{background-color:white;font-size:16px;}

JavaScript Minification Example

Original JavaScript:

// This is a comment
function add(a, b) {
    return a + b;
}

Minified JavaScript:

function add(a,b){return a+b;}

2. Concatenation

Concatenation is to attach two strings to make a single long one. Combining multiple CSS and JS files into one file each can reduce the number of HTTP requests. 

The fewer number of HTTP requests are received, the better the site speed will be. While concatenation can be done manually using the “concat()” method, it is not recommended on large codes. This is simply because too much time will be required and you’ll be frustrated by the end. 

A better way is to use a tool like Gulp that can automate this process. That said, here’s what a concatenated JS code looks like using Gulp.

Example with Gulp

const gulp = require('gulp');
const concat = require('gulp-concat');

gulp.task('concat-css', function() {
    return gulp.src('src/css/*.css')
        .pipe(concat('styles.css'))
        .pipe(gulp.dest('dist/css'));
});

gulp.task('concat-js', function() {
    return gulp.src('src/js/*.js')
        .pipe(concat('scripts.js'))
        .pipe(gulp.dest('dist/js'));
});

3. Asynchronous Loading

Asynchronous loading allows certain things like images or scripts of a webpage to be loaded in the background while the rest of the elements continue to load as well. This way, the rendering of the page won’t be hindered and the overall speed of your site will improve. 

To load JavaScript asynchronously, use ‘async’ or ‘defer’ attributes. What these attributes will do is the first one will signal the browser to download the script while the page is rendering without waiting for the download to be completed. 

The second attribute we mentioned instructs the browser to download the script in the background after some delay or wait until the page has finished rendering before executing the script and user has interacted with the page.

Below is an example JS code that showcases the use of both attributes for asynchronous loading. 

Async JavaScript

<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

This code is an example of loading a Google AdSense script asynchronously.

Defer JavaScript

<script defer src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

This code is an example of loading a Google AdSense script deferred.

4. Inline Small CSS and JS

Inlining small CSS and JavaScript means including the code directly within your HTML file instead of linking to external files. This is done by placing CSS code within the relevant HTML tag as an attribute.

Having said that, if you inline small CSS and JS snippets that are essential for rendering above-the-fold content into your site’s HTML, its loading speed and performance can be increased since the number of HTTP requests and additional round trips will be lowered.

To exemplify this, an inlined CSS code is provided below. 

Inlined CSS

<h1 style="size:48px; color:#fff; margin: 10px;"> HELLO WORLD </h1>

5. Remove Unused CSS and JS

JavaScript and CSS files usually include the scripts and styling of the whole website. It can just so happen that the page the user is trying to load uses only a small portion of that file. To ensure maximum speed, it is important to remove all the unnecessary scripts needed to load a particular page. This is because the unused snippets of code won’t have to be executed in the background. 

Having said that, for CSS, a tool like PurgeCSS can work well and automate the process of removing unused strings. Conversely, for JavaScript, Webpacks’ tree-shaking feature is great. 

To install and configure the plugins of these two tools, enter the following codes and your site’s unused CSS and JS will be removed. 

Unused CSS Removal with PurgeCSS

Installation:

npm install @fullhuman/postcss-purgecss

Configuration:

// postcss.config.js
const purgecss = require('@fullhuman/postcss-purgecss')({
  content: ['./**/*.html'],
  defaultExtractor: content => content.match(/[\w-/:]+(?<!:)/g) || []
});

module.exports = {
  plugins: [
    purgecss,
    require('autoprefixer'),
  ]
};

Unused JS Removal with Webpack

Configuration File:

// webpack.config.js
module.exports = {
  mode: 'production',
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: __dirname + '/dist'
  },
  optimization: {
    usedExports: true,
  },
};

These are the ways to optimize CSS and JS to give a boost to your site’s speed. With everything discussed, our post comes to an end. 

Final Words

When the need for website speed-up arises, you might have to optimize its code. Whether it’s in JavaScript or Cascading Style Sheets, optimizing isn’t an easy task. There are many ways to do it and in this article, we have discussed each one in detail so you can do it yourself easily. We’ve also mentioned some tools that can automate each way for assistance.
