n JavaScript, what will happen if you send an object directly as body in a fetch() POST request without using JSON.stringify() and without setting "Content-Type": "application/json"? A) The request will automatically convert the object to JSON B) The request will fail before reaching the server C) The server may receive [object Object] or unexpected data D) The data will be sent correctly as form-data ✅ Answer: C) The server may receive [object Object] or unexpected data . . . . . . . . #java #python #programming #javascript #coding #programmer #html #developer #css #coder #php #computerscience #software #code #indonesia #webdevelopment #webdeveloper #softwaredeveloper #technology #codinglife #linux #webdesign #development #tech #programmingmemes #softwareengineer #pythonprogramming #programmers #javaprogramming #c #hackforge

🚀 Python Falcon – Waitress Server When building APIs with Falcon, the default development server should not be used in production because it is not efficient, stable, or secure. 🔹 Waitress Server is a production-quality pure-Python WSGI server that delivers reliable performance and works on both Unix and Windows systems. 📌 Why Use Waitress? • Production-ready WSGI server • No external dependencies outside Python standard library • Stable and efficient for deploying Python web applications ⚙ Basic Usage Use the serve() function to run the Falcon application: serve(app, host, port) 🌐 After running the application, open: http://localhost:8000/hello You can also launch the server from the command line: 💡 Using Waitress with Falcon is a simple way to deploy Python APIs in a production environment. #Python #Falcon #Waitress #PythonDeveloper #WebDevelopment #APIDevelopment #Programming #Coding #BackendDevelopment #TechLearning

#Day_03 #Libraries: A library is a set of re-usable functionalities, and every programming language has built-in libraries to it like Header Files in C & CPP Languages and Packages in Java Language same as that .NET Languages are also provided with built-in libraries and we call them “FCL (Framework Class Libraries)” in .NET Framework and “CORE FX” in .NET Core and .NET.

Virtual Threads are a game-changer in Java — but there's a silent performance killer you need to know about: the Pinning Problem. With Project Loom (Java 21+), virtual threads allow you to run millions of lightweight threads without exhausting your OS thread pool. Sounds perfect, right? Not so fast. ⚠️ 𝗪𝗵𝗮𝘁 𝗶𝘀 𝗣𝗶𝗻𝗻𝗶𝗻𝗴? A virtual thread gets "pinned" to its carrier (OS) thread when: → It runs inside a synchronized block or method → It calls native methods or foreign functions When pinned, the carrier thread is blocked — defeating the entire purpose of virtual threads and bringing you back to the old-school thread-per-request bottleneck. 𝗛𝗼𝘄 𝘁𝗼 𝗱𝗲𝘁𝗲𝗰𝘁 𝗶𝘁? Run your app with: -Djdk.tracePinnedThreads=full This logs every pinning event so you can track down the culprit. 𝗛𝗼𝘄 𝘁𝗼 𝗳𝗶𝘅 𝗶𝘁? ✅ Replace synchronized with ReentrantLock ✅ Audit third-party libraries for synchronized usage ✅ Use JDK 24+ where many JDK internals have been migrated away from synchronized Virtual threads are powerful — but only if you avoid the traps. Pinning is one of the most overlooked issues when migrating to Loom-based concurrency. #Java #ProjectLoom #VirtualThreads #Concurrency #SoftwareEngineering #Backend #Java21 #PerformanceTuning

Day 29 — LeetCode Progress (Java) Problem: Valid Palindrome Required: Given a string, determine whether it is a palindrome after converting all uppercase letters to lowercase and removing all non-alphanumeric characters. Idea A palindrome reads the same forward and backward. Instead of creating a cleaned string, we can directly compare characters from both ends while skipping invalid characters. This avoids extra space usage. Approach (Two Pointer) Initialize two pointers: left at start right at end Move left forward until it points to an alphanumeric character. Move right backward similarly. Compare characters ignoring case. If mismatch occurs → return false. Continue until pointers meet. If all checks pass → palindrome. Time Complexity: O(n) Space Complexity: O(1) Pattern Learned Two Pointers + String Filtering (in-place validation) #LeetCode #DSA #Java #TwoPointers #Strings #CodingJourney
