Tutorials, Errors and Exceptions

Its a journey to understand things better. It will have tutorials, any error/exceptions encountered, its resolutions and lots of learning.

🔐 Java is Growing Up!

🔁 Carry Context Seamlessly in Java 25!
With Scoped Values you no longer need messy ThreadLocal hacks.
Bind a value once, execute tasks (even threads), and access the context everywhere inside.

Clean. Safe. Modern. 💼✨

It’s not the loudest update…
But it’s the kind that keeps Java stable, scalable & future-ready 💪

Small change. Big impact. 🌍✨

🚀 Java 25 Level-Up Alert!

Say hello to StructuredTaskScope 👋 — a new way to handle concurrency that actually makes sense!

Instead of messy threads running wild 🕸️
You simply:
✅ Open a scope
✅ Fork tasks
✅ Join results
✅ Close the scope — everything cleaned up ✨

No more orphan threads… no chaos… just structured concurrency 🤝
Perfect for microservices calling multiple APIs at once!

Java devs, it’s time to simplify the complicated 💡
NOTE: Its a java preview feature, which requires enabling it, before use.

Enable it using
> javac --release 25 --enable-preview MyApp.java
> java --enable-preview MyApp

Or include --enable-preview in maven compiler/exec plugin.

Since it uses virtual threads typically (Project Loom), benefits are greatest when you leverage virtual threads / threaded concurrency.

☕ Ever been asked “Write a custom iterator that returns every 2nd element in a list”… and you froze?

Here’s how you don’t stay stuck:
• Build a custom Iterable
• Implement Iterator with your own hasNext() & next()
• Skip ahead (2 at a time) like a pro

Learning the internals of iteration isn’t just geeky — it’s interview-gold.

🚀 From Java Beans to React Components!
If you’ve mastered the backend world of Spring, it’s time to light up the frontend.

Here’s your Roadmap to Learn React — specially crafted for Java & Spring developers 💻✨

From understanding JSX (it’s like templating on steroids) to building fullstack apps with Spring Boot — this guide will take you from “API wizard” to “UI magician.” ⚡

🔥 Swipe through to see how backend brains can master the frontend game!

🚀 Serverless Architecture – the minimalist diet your backend didn’t know it needed!

Gone are the days of managing bulky servers. Just write code, deploy, and let the cloud handle the heavy lifting.

⚡ Pay-as-you-run
☁️ Automatic scaling
😴 No 3 a.m. on-call panic

But hey… remember, “serverless” doesn’t mean “problem-less.” 😉

Which side are you on – Team Cloud ☁️ or Team Server 🖥️?

🚨 When the cloud takes a nap, the internet throws a tantrum.

On Oct 20 2025, AWS’s US-EAST-1 region had a major outage… and suddenly games, streaming, banking, shopping — you name it — locked up.

Root cause: internal plumbing (DNS / load balancers) got wonky.

🛠️ Lesson: Even the biggest platforms can fall. Your architecture? Shouldn’t.

💬 Tell us — did you see the outage? What went down on your side? 👇

Diwali ki hardik subhkamnaye 🪔🪔

#HappyDiwali #diwali2025 #techcontent #DeveloperCommunity

💻✨ When the world celebrates Diwali, backend devs are out here debugging in festive mode.

May your logs glow, your servers stay stable, and your deployment pipelines sparkle brighter than the diyas! 🪔

Tag your favorite dev teammate who deserves paid downtime this Diwali 💥

🤖 “AI will take our jobs!” — said the dev who still can’t find the right Docker container. 😂

AI isn’t your replacement… it’s your teammate who doesn’t sleep.

💡 Reality Check:
• AI helps, doesn’t replace.
• It’s not always right (ask it to explain your code, you’ll see).
• The future belongs to devs who know how to use it smartly.

🔥 So stop fearing it — start prompting like a pro.

💬 Drop a “🤖” if AI already helps you at work, and tag your skeptical coworker!

💔 When Monolith met Microservices… things got complicated.

They started as one big happy codebase.

But soon came long deployments, scaling nightmares, and team conflicts. 😅

So they broke apart — into smaller, faster, independent pieces.

💡 Lesson: Don’t rush the breakup.

Start monolithic, evolve only when scale demands it.
Because sometimes, the grass is only greener because there’s more YAML on the other side. 🌱😂

⚔️ SQL vs NoSQL — The Ultimate Dev Showdown

SQL was built like a strict librarian.
NoSQL was born like a rebellious startup kid.

Both store your data… they just don’t agree on how. 😅

💡 SQL: perfect for structured, relational, and transactional systems.
💡 NoSQL: ideal for fast, scalable, flexible systems with unstructured data.

The real winner? 👉 The one that solves your use case.

💬 Drop a “💾” if you’ve argued about this at least once with your teammates!

True story: Kafka was born because LinkedIn’s data pipelines were a total nightmare.

Their engineers were drowning in logs, queues, and failed cron jobs — until they built something better.

They called it Kafka, because handling distributed logs felt like a Kafka novel.

Today, it’s the backbone of real-time data for Uber, Netflix, and thousands of systems you use every day.

Moral?
Sometimes frustration builds the future. 💪

🐳 Ever had your Spring Boot app work only on your laptop?
Docker fixes that faster than you can say “microservices”

Wrap your app → build → run anywhere.

Stop saying “it works on my machine” and start saying “it works everywhere.” 💪

Trying to configure Spring Actuator endpoints so they’re ‘just right’ is basically the tech version of Goldilocks: too open and you’re leaking secrets, too closed and you can’t even health-check your own app! 😂🔧

Nothing like spending hours on config, finally hitting /actuator/health… and getting a 404.
At least my errors are highly available!

Note to self: double-check those exposure.include settings before exposing my app to the Wild Web. 🚨

Configuring Spring Actuator: Where exposing too little gets you “404 Not Found,” and exposing too much gets you “Plz Stop Hacking Me!” 😂

Health checks are great until your own config gives you a stress test.

When your Spring scheduler updates cron jobs on the fly... it’s basically the DevOps version of “I’ll do it when I feel like it.” 😎⏰

Dynamic schedulers: because restarting the app every time you change a cron is so 2010. 💻😂

Keep your tasks flexible, your coffee constant, and your threads... preferably synchronized. ☕🧠

Ever seen a race condition? It’s like two threads running toward chaos yelling “I got it!” at the same time. 🏃‍♂️🏃‍♀️💥

Turns out synchronized isn’t a vibe—it's survival. 💻

Debugging this mess made me feel like a time traveler in my own code, watching my past self ruin everything in real time. 😂

Lesson learned: code atoms aren’t atomic unless you make them! ⚛️

Sometimes the threads need couples counseling, not debugging. 😅
