Why Everyone Uses localhost:3000 - The History of Dev Ports (3000, 8000, 8080, 5173) Ever wondered why your dev servers always run on localhost:3000 or localhost:5173? These ports have fascinating histories that trace back through decades of developer habits, from Java and Python to Node.js and Vite. Let’s unpack the stories behind them in your own words 😉. #webdev #programming #node #python

GitHub’s 2025 Octoverse report crowns TypeScript as the platform’s top language for the first time, topping Python by ~42,000 contributors. JavaScript takes third, while Java, C#, and PHP remain rock-solid in fourth through sixth. #coding #github

Ever wanted to try C# as quickly as Python or JavaScript. .NET 10 introduces file-based apps so you can run a single .cs file directly from the CLI. This makes C# perfect for tiny tools, quick tests, and script-style automation. You can also add package references directly inside the file with simple directives. Try creating a small one file program today and experience how much quicker C sharp development feels. #dotnet #dotnet10 #csharp #developerexperience #coding #programming #softwaredevelopment

Use your favorite tools — Python, Java, JavaScript, or even GraphQL APIs — to bring graph power into your applications 🚀 Take a look at how in our Intro to Graph database videos and use Neo4j with your apps: https://lnkd.in/daE8r-WV

🚀 Accessing Static Members Using the Class Name in Java (Oop Concepts) In Java, static members are associated with the class itself, not with instances of the class. Consequently, you should always access static members using the class name, rather than an instance of the class or the `this` keyword. Using the class name clarifies that you are accessing a shared, class-level property or method. This promotes code clarity and avoids confusion about the scope of the variable or method.

Day after day, I've been thinking about how to handle high traffic and millions of data loads for inter-service (microservice) communication with maximum performance. The goal: 5x faster than JSON. Finally, I've created a high-performance library for Go and Java, which I've tested and is ready to use.

🌳 Day 68 of Posting on LinkedIn LeetCode 112. Path Sum — Java Solution Today’s problem checks whether a root-to-leaf path exists in a binary tree such that the sum of the node values equals a target sum. This is a classic DFS (Depth-First Search) problem. We recursively explore left and right subtrees, subtracting the node’s value from the target at each step. When we reach a leaf node, we simply verify if the remaining sum matches the leaf’s value. ✅ Approach Use DFS recursion. At each node, subtract its value from the target sum. When a leaf node is reached, check if the remaining sum is zero. Return true if any path satisfies the condition. 🧠 Key Takeaways Classic DFS problem on binary trees Base case: checking leaf nodes Use subtraction to track required remaining sum #leetcode #leetcode112 #dsa #coding #java #binarytrees #programming #tech #interviewprep #softwareengineering #100daysofcode

🚀 Exploring Java Fundamentals with a Practical Twist! Just shared a simple yet powerful Java program that identifies numbers divisible by both 3 and 5 within a user-defined range. It’s a great example of how object-oriented design and basic control structures come together to solve real-world problems. 🔍 What it does: Prompts the user for a range Iterates through numbers from 0 to that range Prints numbers divisible by both 3 and 5 💡 Whether you're just starting out or brushing up on your Java skills, this snippet is a great reminder of how clarity and logic go hand in hand in programming. #Java #Programming #ObjectOrientedDesign #CodingJourney #TechLearning #LinkedInLearning #SoftwareDevelopment
