Hiya!! I am taking a coding course at a University. While it's excellent for learning how to use a lot of complicated concepts in programming, we don't really get to do any projects or create anything yet. I was wondering how to get into that. Are there any resources you might recommend?

Hiya!! 💞

Goodie, you want to build your own projects! That's so good, I love project building! Now, it depends what you're coding (the languages + specific area) e.g. are you learning HTML/CSS/JavaScript (Website building) or is it like Python/Java/C# idk but you get what I'm asking for here, the projects you want to learn and build depends on what you're learning in the first place! But I will give some general advice!

🎥 YouTube

I love YouTube so much, there are thousands of videos on that site for any programming language to building pretty much anything! What I did when I started off was the simple search of "[The coding language] beginner project" and then I get to see what I can build. Now if you get stuck on a snippet of code, Google it and there are sites that will explain it for you. Now, don't fall for tutorial hell where you're watching tutorial after tutorial videos but watching them will give you a good foundation!

🔍 Google

Similar to what I said for the YouTube way, you can Google the same question and it will give you a bunch of project ideas, how to even do them and all you can do also is add more on top, what I mean is don't just watch or read about a project idea, see how you can twist it your own style e.g. recently I watched a React.js tutorial on how to make a to-do app! My twist was I styled it different by adding a frog theme. So the tutorial was my foundation and I just added on top of that to further exercise my skills!

🌐 GitHub

Have a hub for all your projects! After creating your projects, you don't just want it sitting on your computer, you can put it online! I use GitHub - it's a place where you can store all your projects, have a save history so you can go back on old code, even share the static webpages you make (using HTML/CSS/JavaScript) with other people online! The Site | How to use GitHub | Check out my GitHub for reference

📚 Online Courses

Many online platforms offer project-based courses. Websites like Udemy, Coursera, Codecademy and FreeCodeCamp can guide you through creating practical projects step by step. I use Udemy for learning and there are courses that are like "Build 9 web development projects blah blah blah" they're actually really good! BUT you do have to pay for them but if you can't find a good project on YouTube to follow or you can visualise or understand the articles online on how to build one, I suggest getting a course because someone teaches you how to make the project. Udemy is fairly cheap during their sales, going down from £59.99 to £10.99!

🤗 Collaboration

Reach out to classmates to build together, someone is bound to have an idea for something! Collaborative projects not only expand your skill set but also let you learn from others. Great skill to have! You can even collab on GitHub projects - which I am doing right now with people I've met through Tumblr (checkout our project)!

Remember, Rome wasn't built in a day! Start with small projects, gradually challenging yourself with larger ones. The journey of creating is just as exciting as the finished project itself. Happy coding! 😎🙌🏾💻💗

Days 47-50 of coding everyday for a year... It's been stressful

So I worked on with the image on top a game in Unity. I made a reverse murder mystery visual novel for Brackeys game jam. The bottom was me getting a feel for C++ still. Tbh I'm still kind of lost with it, but I'm trying. (it's just so different from C# in some ways). I'm also doing a small coding challenge every morning after I've had my coffee with C# since that's the language I'm going to base most of my career off of (I can do Java/Kotlin, and C++ but C# is special)

Here's a link to the game...

The next few days I'll be working on more C++, and my .Net Maui project. I also might be practicing some coding interview questions/tests since the summer is coming up soon (I did make an impressive fizzbuzz with a twist)

How to Prepare for a Coding Interview

Coding interviews are a crucial part of the tech hiring process. As a candidate, you'll need to showcase your technical skills, problem-solving abilities, and understanding of data structures and algorithms. To succeed, it's essential to be well-prepared. In this article, we'll discuss the steps you can take to prepare effectively and increase your chances of getting hired.

Understanding the Coding Interview Process

Before diving into the preparation, it's important to understand the coding interview process. 

These interviews are not just about writing code; they also test your ability to think critically under pressure and explain your reasoning behind the solutions you propose. Interviewers are interested in understanding your approach to problem solving and how you handle challenges in a real-time setting.

The Role of Coding Interviews in Tech Hiring for Candidates

By evaluating your coding abilities, interviewers can determine if you're the right fit for the job and the company culture. However, it's not just a one-sided test. It's also an opportunity for the candidate to learn more about the company and its work environment.

Developers will only be successful in a role if the environment is one that is conducive to how they like to work, collaborate, and engage. It’s a win-win benefit for both candidates and employers if both sides are equally excited at the prospect of working together.

Different Types of Coding Interviews

Coding interviews can vary in format and structure. Some companies may conduct coding interviews in-person, while others prefer remote interviews. Additionally, coding interviews can be divided into different types, such as whiteboard coding exercises, take-home assignments, or pair programming sessions.

Each type of coding interview has its own unique challenges and requirements. Whiteboard coding exercises, for example, test your ability to write code on a whiteboard while explaining your thought process out loud. Take-home assignments, on the other hand, give you the opportunity to work on a coding problem at your own pace and showcase your problem-solving skills in a more relaxed environment. Pair programming sessions involve collaborating with an interviewer to solve a problem together, demonstrating your ability to work effectively in a team setting.

Essential Skills for Coding Interviews

Preparing for a coding interview requires mastering several essential skills. Let's explore these skills in detail.

Programming Languages to Master

Individuals should be proficient  in at least one programming language commonly used in the industry, such as Python, Java, C++, or JavaScript. Understanding the syntax, data types, control structures, and libraries of your chosen language will help you solve coding problems efficiently.

Problem-Solving Skills

Problem-solving skills are an integral part of a coding interview. Being able to approach a problem strategically, break it down into smaller subproblems, and devise an efficient solution is highly valued. Practice solving coding challenges and algorithms to sharpen your problem-solving abilities.

Understanding Data Structures and Algorithms

Data structures and algorithms are the building blocks of computer science. Familiarize yourself with various data structures like arrays, linked lists, stacks, queues, trees, and graphs. Additionally, learn popular algorithms for searching, sorting, and optimization. Understanding these concepts will help you analyze problems and devise optimal solutions.

Pre-Interview Preparation

Embarking on the journey of pre-interview preparation is akin to laying the foundation for a successful career in the tech industry. The diligence and effort you put into honing your skills now will pave the way for future opportunities and growth. Here are a few steps you should take before the interview.

Review Common Coding Questions

Start by researching and reviewing common coding questions asked in interviews. Online platforms like LeetCode or HackerRank offer a vast collection of coding problems categorized by difficulty levels. Spend time solving these problems to familiarize yourself with the question patterns and potential solutions.

Practice on Coding Platforms

Practicing on coding platforms simulates the interview environment and helps improve your coding skills. These platforms often offer interactive coding challenges, enabling you to practice solving problems under time constraints. Engage in coding competitions or take part in mock interviews to get a real feel for the interview process.

Brush Up on Technical Knowledge

Aside from coding skills, brush up on your technical knowledge. Review key concepts related to your preferred programming language, data structures, algorithms, and system design. Understanding these concepts in-depth will help you during technical discussions and coding challenges.

During the Interview

Now let's focus on what to do during the coding interview to maximize your chances of getting hired.

When you enter the interview room, remember that your body language and demeanor also play a significant role in making a positive impression. A firm handshake, good posture, and maintaining eye contact can convey confidence and professionalism. These non-verbal cues can complement your technical skills and create a well-rounded image for the interviewer.

Effective Communication During Coding Interviews

During the interview, effective communication is crucial. Clearly explain your thought process, rationale, and any assumptions you make while solving a problem. Communicating effectively helps the interviewer understand your approach and evaluate your problem-solving abilities.

Moreover, active listening is equally important during coding interviews. Pay close attention to the interviewer's prompts and questions. This demonstrates your ability to process information in real time and adapt your problem-solving strategy accordingly. Engaging in a dialogue rather than a monologue can showcase your collaborative skills and willingness to take feedback.

Demonstrating Your Thought Process

Interviewers are interested in how you approach problems and arrive at solutions, rather than just the end result. Be vocal about your thought process throughout the interview. Explain the steps you're taking, potential optimizations or trade-offs, and any ideas that come to mind. This demonstrates your ability to analyze problems and think critically.

Also, don't hesitate to ask clarifying questions if you encounter ambiguity in the problem statement. Seeking clarification shows your attention to detail and ensures that you and the interviewer are on the same page. It's better to take a moment to clarify the problem than to proceed with a misunderstanding that could lead you down the wrong path.

Handling Unknown Problems

Not all problems presented in coding interviews are familiar or straightforward. Interviewers often assess candidates' ability to handle unknown problems and think on their feet. When faced with unfamiliar problems, stay calm and logical. Break down the problem, identify patterns or similarities to other problems you've solved, and come up with a step-by-step approach.

Remember, the interviewer is not just evaluating your technical skills but also your problem-solving methodology. Demonstrating resilience in the face of uncertainty and showcasing adaptability can leave a lasting impression. Embrace the challenge of unknown problems as an opportunity to showcase your creativity and resourcefulness in problem solving.

In Conclusion

Preparing for a coding interview requires a combination of technical skills, problem-solving abilities, and effective communication. Understanding the coding interview process, mastering essential skills, and thorough preparation will increase your chances of getting hired. Remember, practice makes perfect, so devote enough time to solving coding problems, reviewing concepts, and gaining confidence.

Addendum: Game Engines

The post about Unity I wrote yesterday was the longest one I’ve published so far, and even then I feel like I left out about a hundred things. One of the most important ones I wanted to talk about was complexity.

When I first moved away from Game Maker in 2018, I really couldn’t imagine actually writing my own games without using a premade engine. I mean, Game Maker is a massive tool that’s been developed for decades, and the source must have thousands of lines of code, right?

Well, yes. But you don’t need to recreate Game Maker. You can make a lot happen with something called MVP; Minimum Viable Product. Let’s look at a practical example.

Super Mario Bros.. Released in 1985, for the Nintendo Entertainment System. Somehow I doubt it ran on Unity.

Objects!

Let’s start with the most important part: the stuff that moves around and does things.

Now, I’ve looked at SMB1’s engine code, and it actually kind of sucks, so I’ll instead focus on a high-level version of a system that matches what SMB1 has, but doesn’t recreate it one to one. Remember, I want to encourage you to get something made yourself, in your own chosen language and framework, instead of getting stuck looking at hex and memory address behaviour.

We can define an object as something that’s interactable, and can change its state. This locks out stuff like the background bushes, clouds, mountains and also the ground (since it remains constant). However, this means that something like brick blocks and question mark blocks are objects.

In its simplest form, an object base would have a few parameters that every object in the game have: X and Y coordinates, current object state, and whether the object is active or not.

Most of the objects in SMB1 are either very boxy or actually just boxes, so for collision we’ll simply use an axis-aligned bounding box.

How you make the object do, you know, object things, probably depends on what language you’re using. In C I’d use some sort of overcomplicated function pointer array to point to object state functions. In more modern (and reasonable) languages like C#, Java and even C++ you’d probably just inherit the class and make the language figure out what to do with the object.

As for actually managing the objects, well that’s quite simple. The camera in SMB1 moves to the right, and never backtracks, so in essence you just have to worry about objects that appear from the right side of the screen. If you spawn objects only as they’d appear on the screen, and despawn them as soon as they disappear off the left side of the screen, you can easily get away with just a fixed-size array of say, 32 indices, and a for loop to update the active objects.

My very first game was quite literally just this. It’s as basic as it gets, and it totally works!

Level creation!

Generally speaking, one of the most frustrating parts in game development are level creation tools. Without a level, you don’t really have a game, and if your tools suck ass and level creation is a pain, your game won’t turn out so good. As of writing this, I’ve spent about 3 months writing a pretty comprehensive level editor for Radium. However, your first game (super mario) won’t be as complicated. We’ll use something tangible as an example again!

Let’s look at world 1-4, the first Bowser castle. At first glance it looks rather complicated, there’s floor, a ceiling, both change height at several points, there’s pits, all sorts of traps. It looks like a cohesive place.

But remember, video games are all smoke and mirrors. Ultimately all of this is just numbers in memory.

With that in mind, if you stare at the stage for a while, you might start noticing some strange details. Ignoring all enemies and simply looking at the ground, you might notice that the level never features any overlapping geometry. Bricks and question mark blocks may occasionally form platforms, but as far as the ground and ceiling goes, there are never any overhangs, tunnels, multi-layered passthroughs… it’s simply all solid blocks.

SMB1 constructs its worlds by defining a floor and ceiling height. The level itself is constructed by placing markers along the stage that change the floor and ceiling height from that point onward. If the floor is 0 grid units high, it’s a bottomless pit. Therefore, if you simply wanted to make a clone of the world generator and Mario’s player controller, the collision detection would at its simplest be whether or not Mario’s feet are below the ground level. For walls, you can scan the stage forward by Mario’s width and see if the ground level changes at all. If it does, you can check if it’s again higher than Mario’s feet level.

Thus, we have a level creation toolset that doesn’t even require tiles. It might not be suitable for a WYSIWYG approach to level design (for that I’d recommend Tiled or similar), but for a starting position you can quite literally just hardcode a list of ceiling/floor height change instructions separated by N amounts of tiles. Level design without an editor.

Conclusion

That’s not all I could talk about, but I already feel like this is a lot to swallow. Stuff like sprite batching, tile rendering, texture atlases etc. are all topics you'll probably encounter sooner or later. I'd really love to go on about stuff like this, but I'm trying to avoid writing a book. My hopes with this post are to showcase that making games outside of the carefully curated toolsets of modern engines isn’t always as difficult as you’d imagine. The likes of Unity and Unreal have made us believe that game engines are gigantic, unscalable mountains of code. In truth, a game engine is simply something that runs a game.

When I started my engine journey in 2018, I hadn't really realized this. I jumped to MonoGame because I thought custom engines were rad, but I didn’t really know how to actually make an engine, let along a game in one. It didn’t take long to figure just how many corners you can cut to just make something work in the most basic of senses. For every challenge, you have infinite solutions, far beyond the templatized ones provided to you by online Unity tutorials.

I made the source code for my first ever custom game open when I finished the game. It was written in about 2 weeks, and during the production I learned MonoGame, C# and engine design philosophies, all for the first time in my life. You can take a gander at it here and witness it in all its hacky glory. Despite that, it’s a game that you can play.

I’ve also opened up the questions page on my Tumblr, so maybe I can assist with some issues you may have when starting out. I hope I’ve at least inspired you to give a shot for outside the box thinking. The game you want to make may be a lot simpler than you initially imagined.

Happy carefree programming!

Unlock Java Interview Success: OOP Concepts Every Candidate Must Know

Why OOP Matters in Java Modular, scalable design: OOP's emphasis on encapsulation, inheritance, and polymorphism enables well-structured, reusable code—it’s what makes Java maintainable and extensible. Industry alignment: Major companies use OOP principles to design systems that evolve gracefully over time, making OOP fluency a professional imperative. Read For More Info : Java OOPs Concepts The 4 Pillars of Java OOP Master these foundational concepts: Abstraction Focuses on exposing what an object does while hiding how it does it. For example, using methods without worrying about internal logic exemplifies abstraction. Encapsulation Bundles data (fields) and behavior (methods) while enforcing privacy via access modifiers. This mechanism promotes data integrity and prevents external misuse . Inheritance Enables a class (subclass) to inherit attributes and behaviors from a parent class, reflecting an "is-a" relationship. It promotes code reuse and logical hierarchy. Polymorphism Allows objects of different classes to respond differently to the same method call. Supports both: Compile-time (overloading): Same method name, different parameters. Runtime (overriding): Subclass provides its specific version of a method    Read For More Info : Java Frameworks   Bonus: Advanced OOP Insights Composition vs Inheritance: Favor composition ("has-a") over inheritance to reduce tight coupling. Access modifiers: Understand private, protected, default, public, and when each is appropriate. Abstract classes & interfaces: Know when to use each—abstract classes for shared code, interfaces for contract separation. Final Prep Checklist 1.      Review definitions and examples for each OOP pillar. 2.      Write and test sample classes demonstrating each principle. 3.      Prepare clear analogies to explain your thought process. 4.      Practice common OOP interview questions along with polished answers.

How do you handle session management in Java for web applications?

1. Intro to Java Session Management 

So, how do you manage sessions in Java for web apps? This is a key question for developers who want to create safe and scalable applications. Session management is all about keeping track of a user's activity on a web app over time. Java has built-in tools for this using HttpSession, cookies, and URL rewriting. Learning how to handle sessions well is an important skill, and taking a Java course in Coimbatore can provide you with hands-on experience. Whether you're just starting out or looking to be a full-stack developer, getting the hang of session concepts is essential for building secure and efficient apps.

2. Understanding HttpSession in Java

So, what about HttpSession? It’s the go-to API for managing sessions in Java. It keeps track of a user's info across several HTTP requests, created by the servlet container. You can access it using request.getSession(). With it, you can store user-specific data like login details or shopping cart items. If you enroll in Java training in Coimbatore, you will learn to create and manage sessions the right way. HttpSession also has methods to end sessions and track them, making it a key part of Java web development.

3. Session Tracking Techniques  

When it comes to tracking sessions, there are some common methods: cookies, URL rewriting, and hidden form fields. Cookies are small bits of data saved on the client side, while URL rewriting adds session IDs to URLs. Hidden fields are less used but are still an option. These methods are thoroughly covered in a Java Full Stack Developer Course in Coimbatore. Knowing these options helps you pick the right one for your project. Each method has its benefits based on your app's security and scalability needs.

4. Importance of Session Timeout  

Managing session timeout is super important for security and user experience. You can set up timeouts in the web.xml file or by using session.setMaxInactiveInterval(). This helps avoid unused sessions from taking up server resources and lowers the risk of hijacking. Sessions automatically end after a certain time without activity. In a Java course in Coimbatore, you’ll learn how to set timeout values that fit your app's needs. Proper timeout handling is part of building secure Java applications.

5. Secure Session Management Practices  

How do you ensure session management is secure in your Java web applications? Always use HTTPS, create new session IDs when a user logs in, and end sessions when they log out. Avoid keeping sensitive info in sessions. Developers taking Java training in Coimbatore learn to apply these practices in real-life projects. Good session management isn't just about saving data; it's about protecting it, which helps safeguard against threats like session fixation.

6. Storing Complex Data in Sessions  

When it comes to more complex data, Java sessions can handle that too. You can store objects using session.setAttribute(), which is great for keeping user profiles and cart items. Just remember that the objects need to be serializable and avoid making the session too big. Practical lessons in a Java Full Stack Developer Course in Coimbatore often touch on these points. Good data storage practices can improve performance and keep your code clean.

7. Session Persistence and Scalability  

In cases where applications are spread across multiple servers, you have to think about sharing sessions. This can be done with persistent sessions or clustering. Tools like Redis and Memcached help manage state across servers. These ideas are often covered in advanced modules of Java courses in Coimbatore. Learning about session replication and load balancing is key to scaling your app while keeping the state intact.

8. Invalidating and Cleaning Sessions  

Another important part of session management is cleaning up. Properly ending sessions is crucial. You can use session.invalidate() when a user logs out to terminate a session. Also, make sure to remove unnecessary attributes to save memory. Good session cleanup is important to prevent memory leaks and keep your app running smoothly. These topics are usually explained in Java training in Coimbatore, teaching students how to manage sessions responsibly.

9. Real-world Applications of Session Management  

Understanding the theory is just one part. How does session management play out in the real world? Examples include e-commerce carts, user logins, and personalized dashboards. Sessions are essential for adding a personal touch. The Java Full Stack Developer Course in Coimbatore includes practical projects where session management is used in real web apps. Learning through practical examples helps solidify the concept and prepares developers for actual job roles.

10. Conclusion with Career Opportunities  

Getting a handle on session management in Java can really open up job opportunities in backend or full-stack roles. With a solid grasp of HttpSession, tracking methods, and security measures, you'll be able to build secure applications. Whether you’re taking a Java course in Coimbatore or pursuing a full-stack course, this is a key topic you shouldn't overlook. At Xplore IT Corp, we focus on making sure our students are ready for the industry with practical session handling skills and more.
