Developed a cross-platform desktop launcher that integrates Python (Tkinter) with a Node.js backend to run classic console emulators through a clean and unified interface. The application scans ROM folders, organizes titles by console and launches games via SameBoy, mGBA and melonDS. The structure already supports persistent settings, control mapping and future UI customization. Below is a preview of the current version running Pokémon Red: More improvements are planned, including a full keybinding editor and multi-platform packaging. #python #nodejs #softwaredevelopment #desktopapps #fullstack #gamedev #emulation #opensource #programming #techproject #developer

I’ve been refining my PyQt framework — a system built around modular widget creation, layout verification, and dynamic UI assembly using factory and verifier patterns. The idea is simple but powerful: instead of manually wiring every widget and layout, the framework handles structure and validation automatically. Every component — from a single label to the main window — is created through consistent, reusable logic that enforces alignment, geometry, and style at construction. It’s taken a lot of iteration to balance abstraction with practicality, especially around layout handling and central widget management. But each debugging session pushes the architecture closer to something scalable, maintainable, and adaptable for any PyQt-based project. Next milestone: expanding the factory to handle stateful page management (multiple windows and transitions). #Python #PyQt #SoftwareEngineering #Programming #FrameworkDesign #CleanCode #ProgressUpdate

Learn in Public: Make the Smallest Possible Palindrome Problem We are given a string. Our goal is to turn it into a palindrome using the fewest character changes. If several palindromes use the same number of changes, we choose the one that is smallest in dictionary order. Example Input: "egcfe" Output: "efcfe" Only one change was needed: g → f. Approach : Two-Pointer && Greedy Method Why I used two pointers Approach A palindrome is symmetric. So we compare the left and right characters and move inward step by step. Why use a char array Java strings cannot be changed directly. Using a char[] makes updates simple. Why choose the smaller character If the characters do not match, at least one must be changed. Setting both to the smaller one: Keeps changes minimal Produces the smallest possible palindrome Does not affect other pairs This makes the greedy method correct. Time Complexity: O(n) Space Complexity: O(n) Code Link : https://ideone.com/X9OL7m What I Learned Two pointers make symmetric problems easy. Choosing the smaller character gives the best smallest palindrome. #LearnInPublic #Java #CodingPractice #Algorithms #TwoPointers #Greedy #Programming #DSA #ProblemSolving #Palindrome #JavaDeveloper #LeetCode #CodingJourney

🚀 Excited to share my latest open-source contribution! I’ve developed Robot Framework ADB Library, a Python library that lets you interact with Android devices directly from your Robot Framework tests using ADB commands. This library is built using the Proxy Design Pattern, so all ADB interactions are handled through a clean, structured interface without exposing the low-level adb complexities to the user. 📦 Available on PyPI: https://lnkd.in/gHDbYt4Q Open-source testers, give it a try and share your feedback! #robotframework #python #adb #automationtesting #opensource #android #designpatterns #proxy

💻 Developed an In-App Keystroke Recorder (Safe) using Python and Tkinter that captures and displays keystrokes typed only within the app’s text box. The tool features a simple GUI that shows a live key log and automatically saves all entries with timestamps to a text file. ✨ Designed with ethics and privacy in mind, it’s ideal for usability testing, accessibility research, and debugging. Includes start/stop control, file selection, and clear log options — all within a clean and user-friendly interface. #Python #Tkinter #MiniProject #Programming #EthicalAI #SoftwareDevelopment #GUI #StudentProject #Innovation

Mastering loops is crucial for building a strong foundation in DSA. Today, I learned how to use loops pattern-wise, and here are the key techniques: Single Index: For simple iteration and element processing Adjacent Elements: For working with pairs (i, i+1) Triplets: For 3-element operations (i, i+1, i+2) Two Pointers: For optimized pair checks in sorted arrays Sliding Window: For dynamic subarray/substring problems Nested Loops: For full pairwise or brute-force comparisons Understanding these patterns helps you identify problem types faster and write cleaner, more efficient solutions. #code #tech #DSA #leetcode #javascript #programming #webdevelopment

🚀 Problem 3: Palindrome Number 💡 Leetcode problem no:9 Today I explored another classic coding challenge — checking if a number is a palindrome 🔁 ✨ Challenge: Determine whether an integer x reads the same forward and backward. If x is a palindrome, return true, otherwise return false. 💻 My Java Approach: 🔹 Stored the original number for comparison 🔹 Used modulus (%) and division (/) to reverse digits 🔹 Compared the reversed number with the original one 🔹 Added a quick check to handle negative numbers efficiently 💙 Tip: Palindrome logic is simple yet powerful — it’s all about understanding digit manipulation and integer handling in Java. #Java #Coding #LeetCode #ProblemSolving #CodingJourney #JavaDeveloper #LeetcodeCoding

✅Modern calculator App with MIPS in backend and GUI with python Ever wondered what happens when you mix the simplicity of Python with the raw fundamentals of MIPS Assembly? I was curious too, so I built a scientific calculator to find out! 😄 It's been a fascinating learning journey creating this full-stack application: 🧠 The Engine (Backend): The core logic is written in MIPS Assembly, handling everything from basic arithmetic and logical operations to more complex scientific functions and even signal convolution. Writing a DSP operation like convolution directly in assembly was quite a challenge! 🎨 The Interface (Frontend): A clean Python GUI that talks to the MIPS backend, featuring plotting capabilities with Matplotlib to visualize results, especially useful for seeing signal operations in action. This project taught me so much about: • Bridging high-level and low-level programming • System architecture and inter-process communication • The beauty (and challenges!) of working close to the hardware It's amazing how understanding fundamental concepts can change your perspective on modern software development. I've open-sourced the project and would love your feedback! Check out the code on GitHub (link in comments) - any suggestions for improvement are most welcome! What's the most educational project you've built recently? #Applied #MIPS #Assembly #Python #LearningJourney #Programming #SoftwareDevelopment #ComputerScience #LowLevelProgramming #OpenSource #DSP #Signals #CalculatorProject#COA#amaad khalil
