☆ 02.10.2023 ☆

Today was the first day of school; we officially started.

I had 2 lectures.

The first one was about operating systems, and we talked about all that happens when you turn on your computer and then turn it off, which was so interesting. The teacher was amazing; honestly, I really liked him. I'll study later today and make a post about it on @codingquill.

The second one was just a little introduction: the professor, again, seemed so cool and well-educated. In this class, we're going to study JAVA JEE for creating web applications. He already gave us an assignment to make the little snake game to check our JAVA skills.

Normally, this evening we would have 2 labs for these exact same classes, but the teachers decided not to do them because we just started.

How was I feeling today?

I honestly did not feel good leaving home. I've been having a depressive episode lately, and once I got to school, I saw my friends, laughed with them, had a nice time, liked the lectures I had, and felt SO MUCH better coming back home.

Which gave the conclusion that uni is actually a place that makes me really happy, and I am so excited for this year to be a good one.

Things I am grateful for?

My good health,

my intelligent mind,

my not giving up mindset,

my friends,

the privilege to study in this field, and the school I am in.

Dev Log Feb 7 2025 - The Stack

Ahoy. This is JFrame of 16Naughts in the first of what I hope will turn out to be a weekly series of developer logs surrounding some of our activities here in the office. Not quite so focused on individual games most of the time, but more on some of the more interesting parts of development as a whole. Or really, just an excuse for me to geek out a little into the void. With introductions out of the way, the first public version of our game Crescent Roll (https://store.steampowered.com/app/3325680/Crescent_Roll juuuust as a quick plug) is due out here at the end of the month, and has a very interesting/unorthodox tech stack that might be of interest to certain devs wanting to cut down on their application install size. The game itself is actually written in Javascript - you know, the scripting language used by your web browser for the interactive stuff everywhere, including here. If you've been on Newgrounds or any other site, they might call games that use it "HTML5" games like they used to call "Flash" games (RIP in peace). Unfortunately, Javascript still has a bit of a sour reputation in most developer circles, and "web game" doesn't really instill much confidence in the gamer either. However, it's turning more and more into the de-facto standard for like, everything. And I do mean everything. 99% of applications on your phone are just websites wrapped in the system view (including, if you're currently using it, the Tumblr app), and it's bleeding more and more into the desktop and other device spaces. Both Android and iOS have calls available to utilize their native web browsers in applications. Windows and Mac support the same thing with WebView2 and WebKit respectively. Heck, even Xbox and Nintendo have a web framework available too (even goes back as far as Flash support for the Wii). So, if you're not using an existing game engine like we aren't and you want to go multi-platform, your choices are either A) Do it in something C/C++ -ish, or now B) Write it in JS. So great - JS runs everywhere. Except, it's not exactly a first-class citizen in any of these scenarios. Every platform has a different SDK for a different low-level language, and none of them have a one-click "bundle this website into an exe" option. So there is some additional work that needs to be done to get it into that nice little executable package.

Enter C#. Everyone calls it Microsoft Java, but their support for it has been absolutely spectacular that it has surpassed Java in pretty much every single possible way. And that includes the number and types of machines that it runs on. The DotNet Core initiative has Mac, Windows, and Linux covered (plus Xbox), Xamarin has Android, and the new stuff for Maui brought iOS into the fold. Write once, run everywhere. Very nice. Except those itty bitty little application lifetime quirks completely change how you do the initialization on each platform, and the system calls are different for getting the different web views set up, and Microsoft is pushing Maui so hard that actually finding the calls and libraries to do the stuff instead of using their own (very strange) UI toolkit is a jungle, but I mean, I only had to write our stream decompression stuff once and everything works with the same compilation options. So yeah - good enough. And fortunately, only getting better. Just recently, they added Web Views directly into Maui itself so we can now skip a lot of the bootstrapping we had to do (I'm not re-writing it until we have to, but you know- it's there for everyone else). So, there you have it. Crescent Roll is a Javascript HTML5 Web Game that uses the platform native Web View through C#. It's a super tiny 50-100MB (depending on the platform) from not having to bundle the JS engine with it, compiles in seconds, and is fast and lean when running and only getting faster and leaner as it benefits from any performance improvements made anywhere in any of those pipeline. And that's it for today's log. Once this thing is actually, you know, released, I can hopefully start doing some more recent forward-looking progress things rather than a kind of vague abstract retrospective ramblings. Maybe some shader stuff next week, who knows.

Lemme know if you have any questions on anything. I know it's kind of dry, but I can grab some links for stuff to get started with, or point to some additional reading if you want it.

if pet hotel had little games and activities like neopets or club penguin puffle games, what would they be?

whatever would be within my skill level to program i guess

i think i would start out with a game where the pet is holding a basket beneath some trees and you have to catch falling fruit by moving the pet left and right. sounds nice and simple enough, and once i had enough of a variety of simple games i would then feel free to try and experiment with something more complex and take as much time as i need since the simple games are able to fill that space where something needs to be right now

if i made this a website-based virtual pet game like neopets and flight rising are, something that's gonna be tricky and would probably take me a long time is i would have to learn how to make an html5 application (which is what these games would be if this was the case, since flash is dead) that would be able to read pet information and user information from a database so the pet could appear in the minigame, be able to modify values like the amount of money the player has so the player can earn money by playing these games, and this database needs to be able to be read and written to by both these minigames and by regular pages like a player's profile page where you'd be able to see your current money balance, for instance. The only experience I have in regards to creating an html5 application is running the html dist Gradle command that libGDX has, which just converts all of your java code into javascript as its own contained thing when for this I would need to make something that actually has the ability to talk to other things. I would have to learn a ton of php in order to make this a thing as well, which I don't have a lot of experience with either.

If I were to turn the pet hotel into a fully-fledged automated and programmable game with my current knowledge and skillset, I think I'd have an easier time using libGDX and Java Swing to make it, and then people would have to download a jar file for it off of itch.io in order to play it. I feel like more people would play it if the game was entirely website-based because people don't really like to download things, which is kind of understandable, but learning web development is really hard and from what little I do know about it I'm kind of bad at it. I took a class where I learned how web sockets work in Java so I think I could be able to make something that connects online like this, but I would have to rent some server space in order to do this so the pet hotel would become something that starts actually costing me money to run if I did this. Also I already have a full-time job so the progress I would make on this would be pretty slow, and sometimes I struggle to muster up the motivation to even just make regular art during the time that I'm not working because my brain just kind of sucks like that. So for now i just run this thing that pretends to be a video game but is actually not because my brain prefers the instant gratification of watching youtube videos and playing video games that other people have already made instead of using that time to learn how to make a video game myself

OS commands injection testing & defense

OS command injection is a technique used via a web interface in order to execute OS commands on a web server.

How to test for the issue

During code review

Check if any command execute methods are called and in unvalidated user input are taken as data for that command.

Besides, appending a semicolon to the end of a URL query parameter followed by an operating system command, will execute the command. %3B is URL encoded and decodes to semicolon. This is because the ; is interpreted as a command separator.

Example: 

http://sensitive/something.php?dir=%3Bcat%20/etc/passwd

If the application responds with the output of the /etc/passwd file then you know the attack has been successful. Many web application scanners can be used to test for this attack as they inject variations of command injections and test the response.

Equally Static Code Analysis tools check the data flow of untrusted user input into a web application and check if the data is then entered into a dangerous method which executes the user input as a command.

Remediation

If it is considered unavoidable the call to a system command incorporated with user-supplied, the following two layers of defense should be used within software in order to prevent attacks

Parameterization - If available, use structured mechanisms that automatically enforce the separation between data and command. These mechanisms can help to provide the relevant quoting, encoding.

Input validation - the values for commands and the relevant arguments should be both validated. There are different degrees of validation for the actual command and its arguments:

When it comes to the commands used, these must be validated against a list of allowed commands.

In regards to the arguments used for these commands, they should be validated using the following options:

Positive or allowlist input validation - where are the arguments allowed explicitly defined

Allow-list Regular Expression - where is explicitly defined a list of good characters allowed and the maximum length of the string. Ensure that metacharacters like & | ; $ > < \ \ !` and whitespaces are not part of the Regular Expression. For example, the following regular expression only allows lowercase letters and numbers, and does not contain metacharacters. The length is also being limited to 3-10 characters:

^[a-z0-9]{3,10}$

Example code - Java

Incorrect Usage

ProcessBuilder b = new ProcessBuilder("C:\DoStuff.exe -arg1 -arg2");

the command together with the arguments are passed as a one string, making easy to manipulate that expression and inject malicious strings.

Correct Usage

ProcessBuilder pb = new ProcessBuilder("TrustedCmd", "TrustedArg1", "TrustedArg2"); Map<String, String> env = pb.environment(); pb.directory(new File("TrustedDir")); Process p = pb.start();

starts a process with a modified working directory

The command and each of the arguments are passed separately which makes it easy to validate each term and reduces the risk to insert malicious strings

The History of Java Programming: From Its Humble Beginnings to Dominance in Software Development

Java is one of the most influential programming languages in the modern era, known for its versatility, portability, and robustness. Developed in the early 1990s, it has left a lasting impact on the software industry, helping build countless applications, from mobile games to enterprise-level software. In this blog, we'll explore Java’s fascinating history, its motivations, its growth, and its influence on today’s technology landscape.

The Genesis of Java

Java originated in the early 1990s as part of a project at Sun Microsystems. The project, initially called the "Green Project," was led by James Gosling, alongside Mike Sheridan and Patrick Naughton. The team's goal was to develop a language for embedded systems, specifically for appliances like televisions, which were beginning to incorporate smart technology.

The language was initially called "Oak," named after an oak tree outside Gosling's office. However, due to a trademark conflict, it was eventually renamed Java. The name "Java" was inspired by a type of coffee popular with the developers, signifying their relentless energy and drive.

Motivation Behind Java's Creation

Java was developed to address several key challenges in software development at the time:

Portability: Most languages of the day, such as C and C++, were platform-dependent. This meant that software needed significant modification to run on different operating systems. Gosling and his team envisioned a language that could be executed anywhere without alteration. This led to the now-famous slogan, "Write Once, Run Anywhere" (WORA).

Reliability: C and C++ were powerful, but they had pitfalls like manual memory management and complex pointers, which often led to errors. Java aimed to eliminate these issues by offering features like automatic memory management through garbage collection.

Internet Revolution: As the internet began to take shape, Java was positioned to take advantage of this growing technology. Java’s platform independence and security made it an ideal choice for internet-based applications.

The Birth of Java (1995)

The Green Project initially produced a device called Star7, an interactive television set-top box. While innovative, it didn't achieve widespread success. However, by the mid-1990s, the internet was gaining traction, and Sun Microsystems realized Java’s true potential as a programming language for web applications.

In 1995, Java was officially launched with the release of the Java Development Kit (JDK) 1.0. At the same time, Netscape Navigator, a popular web browser, announced that it would support Java applets. This gave Java immense exposure and set the stage for its rapid adoption in the software development community.

Key Features that Set Java Apart

From the beginning, Java had several features that distinguished it from its contemporaries:

Platform Independence: Java programs are compiled into an intermediate form called bytecode, which runs on the Java Virtual Machine (JVM). The JVM acts as a mediator between the bytecode and the underlying system, allowing Java programs to be executed on any platform without modification.

Object-Oriented: Java was designed from the ground up as an object-oriented language, emphasizing modularity, reusability, and scalability. This feature made Java particularly attractive for building complex and large-scale applications.

Automatic Memory Management: Java's garbage collector automatically handles memory deallocation, reducing the risk of memory leaks and other errors that plagued languages like C and C++.

Security: Java was designed with a focus on security, particularly given its intended use for internet applications. The JVM serves as a secure sandbox, and Java’s bytecode verification process ensures that malicious code cannot be executed.

Evolution of Java Versions

Since its release in 1995, Java has undergone several iterations, each bringing new features and improvements to enhance the developer experience and address the evolving needs of software applications.

Java 1.0 (1996): The first version of Java was mainly used for applets on web browsers. It came with basic tools, libraries, and APIs, establishing Java as a mainstream programming language.

Java 2 (1998): With the release of J2SE (Java 2 Platform, Standard Edition), Java evolved from a simple web language to a complete, general-purpose development platform. Java 2 introduced the Swing library, which provided advanced tools for building graphical user interfaces (GUIs). This release also marked the beginning of Java Enterprise Edition (J2EE), which extended Java for server-side applications.

Java 5 (2004): Java 5, initially called Java 1.5, was a significant update. It introduced Generics, Annotations, Enumerations, and Autoboxing/Unboxing. The updated version also brought improved syntax and functionality, which simplified writing and reading code.

Java SE 7 (2011) and Java SE 8 (2014): Java SE 7 brought features like try-with-resources, simplifying exception handling. Java SE 8 was a transformative release, introducing Lambda expressions and Stream APIs. This version brought functional programming aspects to Java, allowing developers to write more concise and expressive code.

Java 9 to Java 17 (2017-2021): Java 9 introduced the module system to help organize large applications. Java 11 and later versions moved towards a more rapid release cadence, with new features appearing every six months. Java 17, released in 2021, became a long-term support (LTS) version, offering several advancements like improved garbage collection, pattern matching, and record classes.

The Java Community and OpenJDK

Java's development has always been characterized by a strong community influence. Initially controlled by Sun Microsystems, Java's fate changed when Oracle Corporation acquired Sun in 2010. After the acquisition, Oracle made significant strides towards making Java more open and community-driven.

OpenJDK, an open-source implementation of Java, became the reference implementation starting from Java 7. This move encouraged greater collaboration, transparency, and diversity within the Java ecosystem. OpenJDK allowed more organizations to contribute to Java’s development and ensure its continued growth.

Java in the Enterprise and Beyond

Java has become synonymous with enterprise-level software development, thanks in part to the introduction of Java EE (now known as Jakarta EE). Java EE provides a set of specifications and tools for building large-scale, distributed, and highly reliable applications. The Java ecosystem, including frameworks like Spring, Hibernate, and Apache Struts, has contributed to its popularity in enterprise environments.

Java also became a key player in the development of Android applications. Android Studio, Google's official IDE for Android development, is powered by Java, which contributed significantly to its widespread adoption. Although Kotlin, another JVM language, is now gaining popularity, Java remains a core language for Android.

The Challenges Java Faced

Despite its success, Java faced competition and challenges over the years. Languages like C#, developed by Microsoft, and Python have gained traction due to their developer-friendly features. Java has been criticized for its verbosity compared to more modern languages. However, the Java community’s active contributions and Oracle’s improvements, including adding modern programming paradigms, have kept it relevant.

Another significant challenge was the rise of JavaScript for web development. While Java was initially popular for web applets, JavaScript became the dominant language for front-end development. Java's relevance in web applications decreased, but it found its niche in server-side applications, enterprise systems, and Android.

Java Today and Its Future

Today, Java is one of the most popular programming languages globally, powering applications across various sectors, including finance, healthcare, telecommunications, and education. Java’s strength lies in its mature ecosystem, robust performance, and scalability.

The new six-month release cycle initiated by Oracle has brought excitement back into the Java world, with new features being added frequently, keeping the language modern and in line with developer needs. Java 17, as an LTS version, is a stable platform for enterprises looking for reliable updates and support over the long term.

Looking forward, Java’s evolution focuses on improving developer productivity, adding more concise language features, and optimizing performance. Java's adaptability and continuous evolution ensure its place as a leading language for both new projects and legacy systems.

Conclusion

Java’s journey from a language for set-top boxes to becoming a foundational tool in enterprise computing, Android applications, and beyond is nothing short of remarkable. Its creation was driven by a need for portability, reliability, and ease of use. Over nearly three decades, Java has evolved to remain relevant, keeping pace with technological advancements while preserving its core values of reliability and platform independence.

The language’s robust community, open-source development model, and wide adoption in critical applications guarantee that Java will remain a force in software development for many years to come. It has not only withstood the test of time but continues to thrive in a constantly changing technology landscape—an enduring testament to the vision of its creators and the collective effort of its global community.

This is a fundamental question that often appears in Spring Boot interviews. Spring Boot is an extension of the Spring Framework to simplify the development process. It eliminates the need for extensive XML configuration and provides default configurations to facilitate rapid application development. Spring Framework requires developers to configure components manually, while Spring Boot auto-configures them.

By understanding this, you can highlight how Spring Boot training in Electronic City Bangalore at eMexo Technologies helps developers focus more on writing business logic rather than dealing with complex configurations.

2. What are the main features of Spring Boot?

Spring Boot stands out due to several features:

Auto-Configuration: Automatically configures your application based on the libraries on the classpath.

Embedded Servers: It allows the deployment of web applications on embedded servers like Tomcat, Jetty, and Undertow.

Spring Boot Starters: Pre-configured templates that simplify dependency management.

Spring Boot CLI: A command-line interface that allows you to develop Spring applications quickly.

Actuator: Monitors and manages application performance.

These features make Spring Boot an attractive option for developers, which is why the best Spring Boot training institute in Electronic City Bangalore emphasizes hands-on experience with these functionalities.

3. What is the role of @SpringBootApplication in Spring Boot?

The @SpringBootApplication annotation is a core part of Spring Boot, often referred to as the ‘meta-annotation.’ It is a combination of three annotations:

@Configuration: Marks the class as a configuration class for Spring Beans.

@EnableAutoConfiguration: Enables Spring Boot’s auto-configuration feature.

@ComponentScan: Scans the components within the specified package.

This annotation is crucial to understanding Spring Boot’s internal architecture and its ability to simplify configuration.

4. What is Spring Boot Starter, and how is it useful?

A Spring Boot Starter is a set of pre-configured dependencies that simplify the inclusion of libraries in your project. For instance, spring-boot-starter-web includes everything you need for web development, like Spring MVC, embedded Tomcat, and validation support.

Starters save a lot of time, as they eliminate the need to find and include individual dependencies manually. When studying at eMexo Technologies, you’ll get an in-depth look at the variety of Spring Boot Starters available and their importance in building scalable applications.

5. What is a Spring Boot Actuator, and how is it used?

Spring Boot Actuator provides production-ready features to help monitor and manage your Spring Boot application. It offers a wide array of tools like health checks, metrics, and auditing endpoints. The actuator allows you to easily monitor application performance, which is a crucial aspect of microservices-based applications.

6. What are Microservices, and how does Spring Boot help in building them?

Microservices are small, independent services that work together in a larger application. Each service is responsible for a specific business functionality and can be developed, deployed, and maintained independently. Spring Boot simplifies the development of microservices by providing tools like Spring Cloud and Spring Boot Actuator.

7. How does Spring Boot handle dependency injection?

Dependency Injection (DI) is a key feature of the Spring Framework, and Spring Boot uses it to manage object creation and relationships between objects automatically. In Spring Boot, DI is usually handled through annotations like @Autowired, @Component, and @Service.

8. How can you configure a Spring Boot application?

Spring Boot applications can be configured in multiple ways:

application.properties or application.yml files.

Using the @Configuration classes.

Via command-line arguments.

Environment variables.

9. What are profiles in Spring Boot, and how are they used?

Profiles in Spring Boot allow developers to create different configurations for different environments. For example, you can have one profile for development, one for testing, and one for production. You can specify which profile to use by setting it in the application.properties file or as a command-line argument.

10. What are the limitations of Spring Boot?

Despite its many benefits, Spring Boot has some limitations:

Lack of control over auto-configuration can sometimes lead to unexpected behaviors.

Increased memory usage due to embedded servers.

Limited flexibility in large-scale applications that require extensive custom configuration.

Addressing these limitations demonstrates that you have a well-rounded understanding of the framework and can make informed decisions about when and where to use it.

11. How does Spring Boot handle security?

Spring Boot simplifies security through Spring Security, which can be easily integrated into your application. By adding the spring-boot-starter-security dependency, you can configure authentication and authorization in a few lines of code. You can also customize login, registration, and session management features.

12. What is the role of the Spring Initializr in Spring Boot?

The Spring Initializr is an online tool used to generate Spring Boot projects. It allows developers to choose the dependencies and configuration options before downloading the skeleton code. This tool speeds up the initial setup phase, saving time and effort.

In conclusion, being well-prepared for Spring Boot interviews is crucial, especially in a competitive job market. Whether you're taking a Spring Boot course in Electronic City Bangalore or aiming for Spring Boot Certification Training, knowing these key concepts will give you the edge you need. At eMexo Technologies, you’ll receive hands-on training, not just theory, preparing you to answer interview questions and excel in your career confidently.
