How to create maintainable and scalable software systems? 🧩

Proxify for Developers — Wed, 25 Oct 2023 12:00:00 +0000

Can you create a software system that is easier to maintain and scale?

Creating maintainable and scalable software systems is a key challenge many software developers face. One solution to this challenge is following certain design principles and patterns, such as the SOLID principles and Model-View-Controller (MVC).

Explore SOLID principles and the Model-View-Controller (MVC) to demonstrate how to design modular, flexible, and robust software systems with this newsletter. Using a game model example, understand each principle and pattern and confidently apply them in your projects.

Continue reading for a better understanding of how to create software systems that are maintainable and scalable.

SOLID Principles

SOLID helps you to avoid bad software design patterns, engineering mistakes or technical debts. With SOLID, you can make your code more readable, cleaner, and easier to understand.

Let's use a game as an example to explain each of these principles:

Suppose you are building a simple game where the player controls a character that can move around a 2D platform. Here's how you can apply the SOLID principles:

(S)Single responsibility: a class/module should have a single responsibility or reason to change. This principle helps to keep classes small and focused, making them easier to understand and maintain.

Example: a Player class might be responsible for handling just the movement and actions of the character.

You can create a separate class for each responsibility, such as a Player class for handling the movement and actions of the player character, rather than bundling unrelated tasks in one class like collision detection or sound effects.

(O)Open-closed: to add extensibility and avoid modifying existing code, classes should be designed to be open for extension but closed for modification. In this principle, new functionality can be added without altering the existing codebase. It also helps to prevent code rot by discouraging the modification of working code.

Example: you can add a new type of 'enemy' to the game.
Instead of modifying the existing Enemy class, you could create a new class that extends Enemy and adds the new behavior. This way, you can add new functionality without modifying the existing code.

(L)Liskov substitution: derived classes should be substitutable for their base classes. This principle helps to ensure that derived classes behave as expected when used in place of their base classes. It also makes it easier to refactor code without breaking existing functionality.

Example: a 'GameObject' class may represent any object in the game world. You could create a subclass called player that extends GameObject. Since the player is a subclass of GameObject, you should be able to use Player objects anywhere that GameObject objects are expected without causing any issues.

(I)Interface segregation: classes should not be forced to implement interfaces they do not use. This principle helps to keep interfaces small and focused, making them easier to understand and maintain.

Example: a SoundEffect class can play different sound effects in the game.

You could create an interface called SoundPlayable that has a playSound method. Then, you could create separate classes for each type of sound effects, such as JumpSound, that implement the SoundPlayable interface. This way, you can avoid forcing clients to depend on methods they don't need.

(D)Dependency inversion: High-level modules should not depend on low-level modules. This principle helps to ensure that code is loosely coupled and easier to maintain. It also makes it easier to switch out components without breaking existing functionality.

Example: a GameManager class can manage the game's overall state. This class might depend on lower-level classes such as Player or Enemy. However, you can apply the 'Dependency inversion principle' by defining interfaces for these lower-level classes and having GameManager depend on those interfaces instead. This way, you can swap out different implementations of these interfaces without affecting GameManager.

Model View Controller (MVC) Pattern

A software design pattern separates an application into three main components: the model, the view, and the controller. In addition to defining the roles of objects in an application, the MVC pattern also defines how objects should communicate with each other. This involves creating abstract boundaries between the three types of objects (model, view, and controller) to ensure they interact with objects of other types only across those boundaries.

Let's go into detail for our game example. Imagine your game also allows the player to collect coins. To create this game, you would need to separate the game logic into three components, as follows:

(M)Model: the model component would represent the data and logic of the game. It would be responsible for tracking the player character's location, the coins' positions, and the player's score. It would also implement the game rules, such as collision detection between the player and the coins and updating the score when a coin is collected.

(V)View: the view component would represent the game's user interface. It would be responsible for displaying the game world to the player, including the player's character, the coins, and the score. It would also handle user input, such as keyboard or mouse events, and send them to the controller for processing.

(C)Controller: the controller component would act as the intermediary between the model and view components. It would be responsible for processing user input and updating the model and view accordingly. For example, when the player presses the arrow keys to move the character, the controller updates the character's position in the model and then notifies the view to update the display of the game world.

You can create a more modular and maintainable codebase by separating the game logic into these three components. For example, if you wanted to change how the game world is displayed, you could modify the view component without affecting the model or controller. Similarly, you could modify the model component without affecting the view or controller to add a new game rule, such as a timer.

MVC pattern in Apple's and facebook's software system

Many web development frameworks, including Ruby on Rails, Django, and Spring MVC, have widely adopted the MVC pattern. However, it has also been used in desktop GUI applications like Apple's Cocoa framework.

Facebook's React framework uses the Flux architecture variant of the MVC pattern. Flux introduces the concept of a "store" to manage the application state, which is separate from the model. React components act as the view and controller, updating the store based on user input.

Writing secure code for web applications🔓

Proxify for Developers — Tue, 24 Oct 2023 09:00:00 +0000

Are you putting your web applications at risk by overlooking security in your code? A single leak can lead to devastating consequences, including data loss, financial damage, and harm to your reputation.

With this post, you'll discover the ways and tips for protecting your web app from various attacks. Continue reading to gain the insights you need to make informed decisions. Let's get started and secure your web app.

Security Risks of Web Applications

Web applications face various security risks, including injection attacks, XSS, poor authentication/session management, CSRF, broken access control, misconfigured systems, insufficient logging, and use of vulnerable components.

Injection attacks involve sending malicious code via user input.
XSS involves introducing malicious scripts into web pages.
Poor authentication and session management lead to stolen credentials/hijacked sessions.
Cross Site Request Forgery (CSRF) tricks users into performing actions without knowledge.
Broken access control vulnerabilities can result in unauthorized access to sensitive data/functionality.
Misconfigured systems leave the application open to attack.
Insufficient logging and monitoring make detecting and responding to security incidents hard.
Using outdated/vulnerable components, such as libraries or frameworks, puts the application at risk.

How to write secure code for web applications

Input validation: Use this technique to validate all user inputs to ensure they meet the expected format, length, and type.

Why it's useful: Input validation helps prevent malicious user input from being processed by the application, reducing the risk of security vulnerabilities such as SQL injection and cross-site scripting.
Example: Google uses input validation to prevent malicious user input from being processed by their applications. For example, when a user searches for a term on Google, the input is validated to ensure that it meets the expected format and length, and Google discards any malicious input. It helps protect the users and the systems from potential security threats.

Parameterized Queries: In order to protect the system against SQL injection attacks and keep user inputs separate from the query, use placeholders instead of directly inserting user inputs in a query.

Why it's useful: It prevents attackers from altering the structure of the query and executing malicious actions on the database.
It improves the maintainability of the code and reduces the chance of introducing security vulnerabilities.
Example: Google uses parameterized queries in their applications for better security.

Escape output: Escape output is a technique used to prevent malicious code from being executed when data is displayed on a web page. Escaping special characters ensures that any code included in the data will be treated as plain text instead of executed.

Why it's useful: With this technique, developers can ensure that user-generated data is displayed safely and securely, protecting their web applications and users from potential security threats.
Example: Amazon uses escape output to protect against XSS attacks on its website. This helps to keep customer data and information secure and prevent attackers from injecting malicious scripts into Amazon's pages.

Encryption: Use this technique of converting sensitive data into a code to protect it from unauthorized access.

Why it's useful: Protects sensitive information, such as passwords and financial data, from being viewed or used by unauthorized individuals.
Example: Microsoft uses encryption to protect sensitive customer data, such as payment information, stored in their systems. They use a combination of encryption algorithms and key lengths to ensure that customer data is kept secure.

Access controls: Restrict access to admin pages and only give users the permissions they need to do their job.

Why it's useful: Access controls are important for Implementing controls to prevent unauthorized access to confidential information and functions.
Example: Uber uses access controls to ensure that only authorized employees can access sensitive customer and financial information. It helps prevent data breaches and ensures that sensitive information is only used for legitimate purposes.

Session management: Implement a secure mechanism to manage user sessions in a web application.

Why it's useful: Improper session management can lead to a range of security vulnerabilities, such as session hijacking, where an attacker takes over a user's session, and session fixation, where an attacker can set or predict the value of a user's session ID.
Example: Bank of America uses a combination of secure cookies and encryption to ensure that sessions are safe and protected from attacks.

Third-party components: Carefully evaluate and keep up-to-date with third-party components and libraries used in your application.

Why it's useful: By using well-vetted third-party components and libraries, you can save time, mitigate the risk of security weaknesses, and focus on other areas of development.
Example: Airbnb is a perfect example of a company adopting this best practice. Airbnb extensively relies on open-source software and regularly updates its third-party components to minimize security risks.

Follow these tips to write secure code:

Keep your software up to date: Keep your programming language, frameworks, libraries and dependencies updated to avoid security vulnerabilities.
Use Secure Coding Practices: Follow best coding practices and pay attention to security concerns. Refer to OWASP Secure Coding Guidelines and SANS Institute's Secure Coding Practices Quick Reference Guide.
Know Common Vulnerabilities: Familiarize yourself with common security threats. Start with the OWASP Top 10.
Perform regular security audits: Periodically check for new security issues and perform regular security audits to keep your app secure over time.

But what if you accidentally add too much sugar or forget a necessary ingredient? That's where version control comes in! It's like a recipe book that keeps track of every single ingredient you add or take out and who did it. This way, if you ever run into trouble with the cake, you can just flip through the recipe book, find the exact spot where things went wrong and fix it.

3 most commonly used version control systems

1. AWS CodeCommit

CodeCommit is a fully-managed version control system hosted on AWS. CodeCommit is easy to use and integrates with other AWS services.

To use CodeCommit, you first need to create a repository to store your project files.
You can make the repository accessible to everyone or keep it private.
You must first clone the repository onto your local machine to add files to the repository.
Once you have made changes on your local machine, you can push the changes to the CodeCommit repository.
Other team members will be able to pull the changes and incorporate them into their workflows.

2. Azure DevOps Server

Azure DevOps Server is a powerful and flexible tool for managing software development projects. You can choose a source control system like Git when creating a new project.

Create a remote repository in the Azure DevOps Server interface to set up your project's source code.
You can add your project's files to the repository by clicking "Add Files" in the interface.
Commit changes directly in Azure DevOps Server by selecting the file and clicking "Commit" with a commit message describing the changes.
Once all changes are committed, you can push them to the remote server by clicking "Push" in the interface.

3. GIT

GIT is a powerful version control system that helps to keep track of the codebase and ensure that you are always working with the most up-to-date version.

To use GIT, first create a GIT repository using a command line or GUI tool like SourceTree.
Add files to the repository using the "git add" command, e.g. "git add ." to add all files in the project.
Commit changes using the "git commit" command and enter a message describing the changes made.
Once changes are committed, they are available in the local repository.
Share changes with others by pushing them to a remote repository using the "git push" command.
GIT helps developers keep track of the codebase and work together on projects more effectively.

The best uses of version control systems in top tech companies

Keep a log of revisions or updates: A version control system enables developers to record all modifications made to the codebase, including who made the changes, when they were made, and why they were made. It's essential for debugging and troubleshooting as it allows developers to quickly identify and fix errors and understand how the code has evolved.

Streamline teamwork and collaboration: A VCS makes it easier for team members to collaborate on a project by providing a central repository where everyone can share their changes. That allows team members to work on different parts of the codebase simultaneously without interfering with each other's work.

Rollback changes: If there are any problems with a new change, a VCS makes it easy to roll back that change without having to undo all the other changes that have been made since then. That allows developers to quickly revert to a previous version of the codebase, without losing any of the previous changes.

Save time and keep the code stable: A VCS can save developers a lot of time by automatically tracking and managing dependencies between different code versions. That allows developers to easily switch between different codebase versions and ensure that the code is always stable.

How to choose the best version control system for your project?

Many options are available when choosing a version control system (VCS) for your project. To help you make the best decision, here are some critical questions to keep in mind:

1. Do you need a centralized or decentralized system?

Centralized VCSs store all project files in a central repository, which all team members can access. This setup is simple and easy to use but can be susceptible to data loss if the central server goes down.
Decentralized VCSs allow each team member to have their local copy of the repository. That is more robust since there is no single point of failure, but it can be more challenging to manage since changes must be manually synchronized between repositories.

2. What kind of workflow do you need?

Choose a VCS with a workflow that fits your team's needs. Git supports a linear workflow with separate branches, while
Subversion uses a centralized workflow with a single branch

3. What platform do you need?

Ensure the VCS you pick supports your team's operating system, some VCSs only work on Windows or Mac, and others are cross-platform.

4. How much do you need to customize?

Choose a VCS that fits your project's needs. Some like Git have advanced customization options while others like Subversion, have more limited capabilities.

With so many options and features available, it's essential to find the right one that fits your team's workflow and project requirements. I hope this article has given you helpful information on how to use version control systems and provided some insights into choosing the best tool for you.

Troubleshooting and debugging strategies for software developers ⌨️

Proxify for Developers — Wed, 18 Oct 2023 08:09:00 +0000

Even the most seasoned software developers will sometimes encounter challenges that seem impossible to solve. But it's not the challenge that matters; your ability to solve it effectively and fast matters the most. That's why it's crucial to have a systematic approach to debugging and troubleshooting, so you can swiftly resolve any issues that arise. You can save valuable time with the right tools and strategies for identifying and solving bugs. Don't let tricky bugs slow you down - teach yourself a proven process to problem-solving, and you'll be able to solve any bug issue that comes your way.

As a software developer, you can use different tools and strategies when debugging software development issues. Keep reading and learn about some of the strategies and methods you can use to speed up the troubleshooting and debugging process:

Debugger:

A debugger is a tool that helps you identify and fix errors in your code by allowing you to execute it line by line and examine its behavior at each step.
Debuggers allow you to examine variable values by hovering over them, which can help you understand why the code is not working as expected.
Fusion Reactor, Data Display Debugger, Lightrun, GBD, Ghidra, and PurifyPlus are some debugger tools you can try and test.

Logging:

Logging is a way of tracking what is happening in your code.
Logging is a helpful tool for debugging software applications, as it provides information about what went wrong and why.
There are different levels of logging, including debug, info, warn, and error, which can instruct the printing of different messages.
Warnings indicate potential problems that might occur in the future.
Information contained in each level of the message can help you effectively use logging for debugging.

Zooming in and out:

It can be helpful to take a step back and look at code from a high-level perspective to debug it more effectively.
Zooming in on the problem area and then zooming out to see how it fits into the larger context can help find the root cause of the problem.
When zooming in, look at individual lines of code and trace the execution to identify where the problem is occurring.
When zooming out, consider other functions that may be affected by the problem, the data being passed around, and any other potential issues.

The XY problem

The XY problem is a way of approaching problems that can be effective for debugging.
There are two approaches to fixing a bug: starting with the code causing the bug or starting with the symptoms of the bug.
Starting with the symptoms of the bug can often be quicker and easier, as it allows you to systematically test different parts of your code to identify the root cause of the problem.

Asking for the right context:

It is important to ask for the right context when communicating about a bug to have all the necessary information to debug it effectively.
Make sure to ask the following:
What exactly is the problem, and provide a specific example?
What steps preceded the problem?
What version of the software is being used?
What operating system is being used?
Any other information about the environment that may be relevant
Asking for all necessary details upfront can save time in the long run and prevent going in circles without all the required context.

Reproduce:

Isolating the bug by removing unnecessary code and dependencies can help simplify the test case and make tracking the root cause easier.
Having a clear and concise description of the bug before starting to debug can help you focus on fixing the problem.
Constructing a test case that always reproduces the bug can be more efficient in the long run.
Effectively reproducing the bug can lead to a faster and smoother development process overall.

Read error messages:

Error messages contain important clues about what's wrong with your code.
Reading error messages and using Google effectively can help you fix your code.
Look for the line number where the error occurred and the type of error.
Google can be a helpful resource for finding solutions, be specific in your search terms and include the programming language you are using.
Stack Overflow can be helpful for finding discussions and solutions to common errors.
Testing out various approaches and determining the most suitable one for your situation can be helpful.

Profilers:

If your software is slow or lagging. Using a profiler can help you identify the slow parts to investigate the issue or what part you need to optimize your code.
Different types of profilers can help identify issues with CPU usage, memory usage, and I/O operations.
Choosing the right profiler for your needs is important.
CPU profilers can be a good starting point for optimization.
Using profilers effectively may require patience and trial and error but can lead to more efficient and less buggy code.

Documentation:

Documentation can be a valuable resource for debugging; reading through language, environment, and library documentation can help you understand available features and capabilities.
Documenting your own code as you write it can save time when debugging or making changes later.
Clear and concise comments can make it easier to understand the purpose and behavior of your code.

As you evolve and work on more complex problems as a developer, chances are you will encounter new bugs and challenges. Sometimes it can take quite a bit of trial and error before you finally figure out the issue. However, if you keep these troubleshooting tips in mind, you should be able to identify and fix most errors quickly.

What approach have you found to be the most helpful and practical for quickly solving bugs as a software developer? Please share it with other software developers by leaving a comment in the comments section.
