DEV Community: Md Mijanur Molla

I Built a “Rage Click Simulator” Game… And the Button Started Roasting Me 😭😂

Md Mijanur Molla — Wed, 20 May 2026 11:58:51 +0000

We’ve all seen those buttons.

You move your cursor closer.

You’re ready.

You’re confident.

And suddenly...

👉 The button runs away.

Excuse me? 😭

So I thought:

Why not turn this frustration into a game?

That became:

👉 Rage Click Simulator

And honestly...

It became way funnier than expected 😄

🎮 The Game Idea

The goal sounds ridiculously simple:

Click the button.

That’s it.

No complex controls.

No difficult mechanics.

Just...

Click.

But there’s one problem:

👉 The button does NOT want to be clicked.

😈 Things Get Worse Quickly

As soon as your cursor gets close:

Button changes position
Button moves away
Button becomes faster
Button starts trolling you 😭

Sometimes it even changes text:

Click Me 😄
Almost 😈
Too Slow
Nope 😂
Nice Try Human

The disrespect level becomes unreal.

🧠 Difficulty Progression

At first:

Easy.

Then suddenly:

Speed increases
Fake buttons appear
Chaos mode activates
Screen starts shaking 😭

And now...

You're not playing a game anymore.

You're negotiating with a button.

💻 Challenge Rules

Build everything using:

HTML
CSS
Vanilla JavaScript

Inside:

👉 ONE single HTML file

No frameworks.

No libraries.

Pure frontend chaos.

🎨 UI Style

Fun, colorful and slightly evil 😄

Ideas:

Floating emojis
Smooth animations
Meme effects
Rage meter
Funny button messages

Because this game should feel:

👉 Annoying in the most entertaining way possible.

Some start as coding projects...

Then become emotional damage 😭

🎯 Final Thought

Some games test skill.

Some games test speed.

This one...

👉 Tests patience.

And honestly?

The button is winning 😂

I Built a “Stack Overflow Survivor” Game… And My Stress Reached 100% 😭💻

Md Mijanur Molla — Tue, 19 May 2026 12:45:45 +0000

Every developer knows this feeling.

You start fixing one bug.

Then suddenly:

👉 API breaks

👉 CSS disappears

👉 Console throws 27 errors

👉 Stack Overflow tabs become your best friends

And somehow...

Now you're debugging problems you didn’t even have before 😄

That gave me an idea:

What if coding stress became a game?

So I built:

👉 Stack Overflow Survivor

And honestly…

It feels dangerously realistic.

🎮 The Game Idea

The concept is simple:

Random coding disasters appear.

You must:

Read the problem
Pick the correct fix
Survive the chaos

Sounds manageable...

Until pressure kicks in 😈

🧠 Problem Examples

You might see:

Problem:

Button click not working

Choices:

A) Add event listener

B) Restart laptop

C) Add 500 console.logs

D) Blame CSS

Or:

Problem:

API returns undefined

Choices:

A) await response.json()

B) Refresh page 9 times

C) Pray

D) Rename variables randomly

Some options are useful.

Some are things developers secretly do 😭

⚠️ The Twist

Wrong answers don't just reduce points.

They increase:

👉 Developer Stress Level

And when stress reaches 100%...

Game Over 💀

Suddenly:

You are not fixing bugs.

You are surviving them.

⏳ Things Get Worse Over Time

As levels increase:

Timer gets shorter
Problems become harder
Fake solutions appear
Panic increases dramatically 😄

Basically:

Real-world debugging simulator.

💻 Technical Rules

Build everything using:

HTML
CSS
Vanilla JavaScript

Inside:

👉 ONE single HTML file

No frameworks.

No libraries.

Just creativity and controlled suffering 😄

🔥 Bonus Chaos Ideas

Imagine random events like:

☕ Coffee Boost

💀 Stack Overflow Down

🤖 AI gives suspicious advice

🚨 Friday Deployment Mode

Now things become dangerous.

👉 https://vibecodearena.ai/beattheheat?page=1&pageSize=10&sortBy=responses&sortOrder=desc&utm_source=external&utm_medium=vc3&utm_campaign=beattheheat

Some of them start as games...

And slowly become emotional damage 😭

🎯 Final Thought

Debugging isn't about finding bugs.

It's about staying mentally stable while finding them.

And honestly...

That might be the harder challenge 😄

Why System Design Is Slowly Becoming a Core Skill for Everyone

Md Mijanur Molla — Tue, 19 May 2026 08:52:34 +0000

For a long time, many developers believed system design was only for senior engineers.

Something you learn before big interviews.

Something only architects need.

Something that becomes important after 5 or 10 years of experience.

I used to think the same.

But recently, I started noticing something interesting.

System design is no longer a "senior-only skill."

It is slowly becoming important for almost everyone.

And not just for backend developers.

Not just for architects.

Almost every developer is starting to feel its importance.

Earlier, Writing Code Was Enough

A few years ago, many projects were smaller.

You built a feature.

Connected a database.

Created APIs.

Deployed the application.

Done.

The focus was mainly on:

• Writing working code
• Finishing tasks
• Learning frameworks
• Delivering features

And honestly, that worked.

But software systems today are different.

Applications are larger.

Users are everywhere.

Traffic grows unexpectedly.

Features depend on many services.

Things become complicated very quickly.

Modern Applications Are No Longer Simple

Think about the apps we use every day.

Food delivery apps.

Banking apps.

Shopping platforms.

Social media platforms.

Behind a simple button click, many things happen:

• APIs communicate
• Databases process data
• Services talk to each other
• Authentication systems validate users
• Notifications get triggered
• Background jobs start running

Users only see one screen.

Developers see an entire system.

That is where system design enters.

Problems Start Appearing at Scale

Most applications work fine with:

10 users

100 users

Even 1,000 users

But things become very different at:

100,000 users

1 million users

10 million users

Questions start appearing:

What happens if traffic suddenly increases?

How will data be stored?

Can servers handle the load?

How do we avoid failures?

What happens if one service crashes?

Writing code alone does not answer these questions.

System thinking does.

System Design Is Not Only About Big Diagrams

When many people hear system design, they imagine huge architecture diagrams.

Boxes.

Arrows.

Servers.

Complex terms.

Distributed systems.

Microservices.

But system design starts much earlier.

Even simple questions involve system thinking:

• Should we cache data?
• Should this process run in the background?
• How many API calls are happening?
• Can database queries be optimized?
• Can users face delays?

These decisions happen every day.

Even small projects have design choices.

AI Is Making This More Important

AI can now help generate code quickly.

It can suggest functions.

Create APIs.

Write components.

Generate documentation.

That is useful.

But AI usually focuses on local solutions.

A function.

A file.

A feature.

Humans still think about the bigger picture.

Questions like:

How does everything connect?

Will this scale?

Will this break later?

How maintainable is this?

System thinking becomes more valuable because someone still needs to understand the entire structure.

Developers Are Becoming Problem Solvers

The role of developers is changing.

Companies are not only looking for people who can write syntax.

They increasingly want people who can:

• Understand architecture
• Make design decisions
• Think about scale
• Predict problems
• Build maintainable systems

Because coding is only one part of engineering.

Understanding systems is another.

And that part keeps growing.

Final Thoughts

Maybe you do not need to become a system design expert tomorrow.

You do not need to memorize every architecture pattern.

But learning how systems work together is becoming important.

Because software is growing.

Complexity is growing.

Expectations are growing.

And system design is slowly moving from:

"A skill for senior developers"

"A skill for every developer."

What do you think?

Should developers start learning system design earlier in their journey?

I Built a “Truth or Trap” Game… And My Brain Kept Falling for It 😵‍💫🧠

Md Mijanur Molla — Sat, 16 May 2026 10:02:22 +0000

At first, I thought:

“This will be easy.”

Read a statement.

Choose TRUE or FALSE.

Move on.

Simple.

Then the game showed:

👉 A kilogram of iron is heavier than a kilogram of cotton

And suddenly…

My confidence disappeared 😭

So I built a small game called:

Truth or Trap

And honestly?

It became much more difficult than expected.

🎮 The Game Idea

The concept is simple:

A statement appears.

You decide:

👉 TRUE

or

👉 TRAP

That’s it.

But the twist is:

Some statements are intentionally designed to confuse your brain.

🧠 Examples

You might see things like:

2 + 2 + 2 = 8
A kilogram of iron is heavier than cotton
GREEN written in RED means GREEN
February has 30 days

Some look obvious.

Some look correct.

And some completely destroy your confidence 😄

⚠️ What Makes It Hard

The game mixes:

Logic traps
Visual confusion
Math tricks
Pattern illusions
Psychological misdirection

And as difficulty increases:

👉 Your brain starts trusting the wrong things

⏳ Pressure Makes It Worse

You don’t have unlimited time.

Every round includes:

Countdown timer
Score system
Limited lives
Faster progression

So now you're thinking under pressure.

And that changes everything.

💻 Challenge Rules

Build the entire game using:

HTML
CSS
Vanilla JavaScript

Everything inside:

👉 ONE single HTML file

No frameworks.

No libraries.

Just creativity + logic.

I’ve been exploring creative game-style coding challenges recently:

👉 https://vibecodearena.ai/beattheheat?page=1&pageSize=10&sortBy=responses&sortOrder=desc&utm_source=external&utm_medium=vc3&utm_campaign=beattheheat

Some look simple...

Until they completely trick your brain 😈

🎯 Final Thought

Sometimes wrong answers happen because you don't know.

And sometimes...

👉 Your brain confidently lies to you.

That second one is much scarier 😭

The Future Developer Stack: AI + Automation + Human Judgment

Md Mijanur Molla — Sat, 16 May 2026 09:30:35 +0000

A few years ago, the developer journey looked pretty simple.

Learn a programming language.

Learn a framework.

Build projects.

Deploy applications.

Get better over time.

Then things started changing.

Cloud came in.

DevOps became important.

Microservices arrived.

And now another layer has quietly entered the developer world:

AI.

Today, being a developer is not only about writing code anymore.

The future developer stack is slowly becoming:

AI + Automation + Human Judgment

And honestly, this combination might define the next generation of software engineers.

The Old Stack vs The New Stack

Earlier, many developers focused mainly on:

Programming languages
Frameworks
Databases
APIs
Deployment tools

Those things are still important.

But now the stack is growing.

Today's developers are also learning:

AI tools
Automation workflows
Prompt engineering
System thinking
Decision making
Product understanding

Because technology is changing how work gets done.

AI Makes Developers Faster

Let's be real.

AI tools today can:

Generate code
Explain complex logic
Write SQL queries
Suggest fixes
Create documentation
Help with debugging
Speed up learning

Many developers use AI daily now.

Instead of spending 30 minutes searching for an answer, developers can get help in seconds.

That is powerful.

But there is something important many people forget.

AI gives answers.

Developers still need to decide whether those answers are correct.

Because fast wrong code is still wrong code.

Automation Removes Repetitive Work

Developers spend a surprising amount of time doing repetitive tasks.

Things like:

Running tests
Deploying applications
Sending notifications
Data processing
Monitoring systems
CI/CD pipelines

Automation handles these tasks extremely well.

The goal is not replacing developers.

The goal is removing unnecessary work.

When repetitive tasks disappear, developers get more time for important things:

Thinking.

Designing.

Solving problems.

That is where real value comes from.

Human Judgment Is Becoming More Important

This might be the most underrated skill.

AI can generate code.

Automation can run workflows.

But neither truly understands:

Human emotions
Business priorities
User behavior
Tradeoffs
Real-world context

Imagine AI builds two solutions.

Both work.

Now someone needs to decide:

Which one is scalable?

Which one is secure?

Which one is easier to maintain?

Which one creates better user experience?

That decision still belongs to humans.

And that is judgment.

The Developer Role Is Quietly Changing

A lot of people ask:

"Will AI replace developers?"

Maybe that is the wrong question.

A better question is:

"How will developers change because of AI?"

Future developers may write fewer lines of code.

But they may spend more time:

Understanding problems
Making decisions
Designing systems
Connecting business needs with technology
Managing AI tools

Developers may slowly become technology decision makers instead of only code writers.

That is a huge shift.

Coding Is Becoming Easier

Thinking Is Becoming Harder

For years, coding itself was the difficult part.

Now AI helps generate code quickly.

So the difficult part is changing.

Today the challenge is:

Understanding requirements.

Understanding users.

Understanding systems.

Making smart decisions.

Because anyone can generate code.

Not everyone can build the right thing.

Final Thoughts

The future developer stack is probably not:

HTML + CSS + JavaScript + Frameworks

It may become:

AI + Automation + Human Judgment

AI can improve speed.

Automation can improve efficiency.

But human judgment gives direction.

And direction matters more than speed.

Because building software was never only about writing code.

It was always about solving problems.

What do you think?

Will future developers become coders, AI operators, or decision makers?

I would genuinely love to hear your thoughts.

Why Human Skills Are Becoming More Valuable in the AI Era

Md Mijanur Molla — Fri, 15 May 2026 09:15:56 +0000

AI is getting smarter every day.

It can write emails.
Generate code.
Create designs.
Answer questions in seconds.

So naturally, many people are asking:

"Will AI replace humans?"

But here’s something interesting...

As AI grows, human skills are becoming even more valuable. Recent workplace trends show that skills like communication, leadership, problem-solving, and adaptability are becoming more important, not less. :contentReference[oaicite:0]{index=0}

💡 Because AI can do tasks.

But humans create connection.

AI can give answers.
But humans understand emotions.

AI can process data.
But humans make difficult decisions.

AI can automate work.
But humans build trust.

That’s why companies are now looking beyond technical skills.

They want people who can:

✔️ Communicate clearly

✔️ Think creatively

✔️ Solve real problems

✔️ Work with people

✔️ Adapt to change

🌱 The future is not humans vs AI.

The real future is:

Humans + AI = Better results.

Because technology may keep changing...

But being human will always matter.

👉 Which human skill do you think will become most important in the AI era?

I Thought This Was Just a Fun Coding Challenge… Then I Saw People Competing Against AI 🔥

Md Mijanur Molla — Sat, 09 May 2026 10:59:54 +0000

At first, I expected something casual.

Maybe a few frontend mini games.

Maybe some simple browser challenges.

But after exploring VibeCode Arena’s Beat The Heat event…

👉 It became surprisingly addictive.

Because this is not just “solve and leave” coding.

It’s:

Build
Compete
Improve
Compare against AI
Climb the leaderboard

And honestly?

That changes everything.

🎮 What Makes It Different

Most coding platforms focus only on:

DSA
Algorithms
Standard interview problems

But this challenge is different.

Here you build:

Browser games
Interactive logic systems
Creative frontend experiences

Using:

HTML
CSS
Vanilla JavaScript

No heavy frameworks.

Just creativity + execution.

🧠 The Fun Part

Some challenges look simple…

Until you actually try solving them 😄

You start thinking:

👉 “Okay this is easy.”

Then suddenly:

Edge cases appear
UI logic becomes tricky
Timing breaks
AI solutions start competing too

And now you want to improve your score again.

⚔️ Human vs AI Makes It More Interesting

One thing I really liked:

You can literally compare your solution with AI-generated solutions.

That creates a different mindset.

Instead of just:

👉 “Does my code work?”

You start asking:

👉 “Can I build this cleaner than AI?”

And that’s where the challenge becomes exciting. :contentReference[oaicite:0]{index=0}

🔥 Why You Should Try It

If you enjoy:

Frontend projects
Game development
Creative coding
UI/UX challenges
Logic-heavy interactions

You’ll probably enjoy this a lot.

Especially because:

👉 The leaderboard makes everything competitive.

Once you see people scoring high…

You automatically want to improve your own build 😄

🚀 Try My Challenge Here

I’ve been exploring and creating challenges here:

👉 https://vibecodearena.ai/beattheheat?page=1&pageSize=10&sortBy=responses&sortOrder=desc&utm_source=external&utm_medium=vc3&utm_campaign=beattheheat

Try building something.

Or try beating existing solutions.

And trust me…

Some challenges look easy until they completely break your brain 😭

🎯 Final Thought

AI can generate code fast.

But creative thinking, interaction design, weird edge cases, and fun gameplay?

👉 That’s still where humans shine.

So if you want something more fun than routine coding practice…

This is genuinely worth trying 🔥

What Really Happens When You Upload File to the Cloud

Md Mijanur Molla — Wed, 06 May 2026 12:34:55 +0000

Uploading a file feels simple.

You click:

👉 Upload

Select a file…

And within seconds:

👉 It appears in the cloud.

Google Drive. Dropbox. OneDrive. Everywhere.

But behind that simple action…

A lot of engineering is happening.

Let’s break it down 👇

💡 Step 1: You Select a File

It starts with something simple:

Image
Video
PDF
Document

Your browser or app now reads the file from local storage.

At this point:

👉 The file still exists only on your device.

📦 Step 2: File Gets Prepared

Before uploading, the system often:

Checks file size
Validates file type
Compresses data (sometimes)
Splits large files into chunks

Why chunking?

Because uploading a huge file at once is risky.

If upload fails at 99%…

💀 everything would restart.

So systems upload in smaller parts.

Smart move.

🌐 Step 3: Upload Request Starts

Now your app sends a request to a server.

Usually using:

```http id="yj4f4r"
POST /upload




Along with:

* File data
* Metadata
* Authentication token

Now the internet journey begins.

---

## 🔐 Step 4: Secure Connection Happens

If using HTTPS:

* SSL/TLS encryption starts
* Data becomes secure during transfer

This prevents attackers from reading your file during upload.

Very important.

---

## 📡 Step 5: File Travels Across Networks

Your file now moves through:

* Routers
* ISPs
* Data centers
* Cloud infrastructure

All this happens surprisingly fast.

Even for large files.

---

## ☁️ Step 6: Cloud Server Receives the File

Cloud servers receive file chunks.

Then systems:

* Reassemble chunks
* Validate integrity
* Check for corruption

If something is broken:

👉 Upload may retry automatically

That’s why modern uploads feel smooth.

---

## 🗄️ Step 7: File Gets Stored

Now the file is stored in cloud storage systems like:

* Amazon S3
* Google Cloud Storage
* Microsoft Azure Blob Storage

But here’s the interesting part:

👉 Your file may not exist in just one place.

---

## 🔄 Step 8: Replication Happens

Cloud providers often create:

* Multiple copies
* Across different servers
* Sometimes across regions

Why?

Because if one server fails…

👉 Your file still survives.

That’s reliability engineering.

---

## ⚡ Step 9: CDN & Fast Access

If your file is accessed frequently:

Systems may cache it using CDNs.

This helps users worldwide download faster.

That’s why cloud files feel instant.

---

## 🧠 Step 10: Metadata & Permissions

The system also stores:

* File name
* Upload time
* Owner
* Access permissions

This controls:

👉 Who can see the file
👉 Who can edit it
👉 Who can download it

---

# 🔥 What Looks Simple Is Actually Complex

That one upload button may involve:

* Frontend logic
* APIs
* Security systems
* Distributed storage
* Replication
* Retry mechanisms
* Global infrastructure

Huge engineering.

---

## ⚠️ What Can Go Wrong?

A lot.

* Network interruption
* Corrupted chunks
* Permission issues
* Storage failures
* Large file timeout

Modern cloud systems handle all these quietly.

That’s why users rarely notice problems.

---

## 🎯 Real Engineering Insight

Cloud uploads are not just:

👉 “Send file to server”

They are carefully designed systems focused on:

* Reliability
* Scalability
* Security
* Performance

That’s modern software engineering.

---

## 🚀 Final Thought

Next time you upload a file…

Remember:

Behind that tiny progress bar,

👉 Massive distributed systems are working together in milliseconds.

And honestly…

That hidden complexity is what makes modern technology so fascinating 💙

AI vs LLM vs AI Agents vs Automation — What’s the Real Difference?

Md Mijanur Molla — Wed, 06 May 2026 06:51:08 +0000

These days, you hear these terms everywhere:

AI
LLM
AI Agents
Automation

And honestly…

👉 They often get mixed up.

So let’s clear it in a simple, practical way 👇

💡 1. What is AI?

AI (Artificial Intelligence) is the big umbrella.

👉 It means machines that can perform tasks that normally require human intelligence.

Examples:

Image recognition
Speech recognition
Recommendation systems (like YouTube, Netflix)

👉 So remember:

AI = everything smart done by machines

🧠 2. What is an LLM?

LLM = Large Language Model

This is a type of AI focused on language.

Examples:

Chatbots
Code generation
Text summarization

LLMs are trained on massive text data and can:

Understand prompts
Generate responses
Write code

👉 So:

LLM ⊂ AI (subset of AI)

⚙️ 3. What is Automation?

Automation is different.

👉 It means doing tasks automatically using predefined rules.

Examples:

Sending emails automatically
Running scheduled jobs
CI/CD pipelines

Important:

No intelligence required
No learning
Just rules + triggers

👉 So:

Automation = “Do this when that happens”

🤖 4. What are AI Agents?

AI Agents are the next level.

👉 They combine AI + decision-making + actions

An AI agent can:

Understand a goal
Plan steps
Use tools (APIs, browser, code)
Execute tasks

Example:

“Book a flight for me”

Agent will:

Search flights
Compare prices
Fill forms
Complete task

👉 That’s beyond just answering.

🔄 Simple Comparison

Concept	What It Does	Intelligence Level
AI	General smart systems	High
LLM	Works with text/language	High
Automation	Executes predefined tasks	Low
AI Agents	Think + decide + act	Very High

🧠 Easy Way to Understand

Think like this:

Automation = Robot following instructions
LLM = Smart brain for language
AI = Entire intelligence field
AI Agent = Smart assistant that can act

⚡ Real Example

Let’s say:

👉 “Send a report every day”

Automation:

Sends report at 9 AM daily

LLM:

Can generate the report text

AI Agent:

Collects data
Generates report
Sends email
Adjusts based on changes

Huge difference.

🔥 Why This Matters for Developers

Understanding this helps you:

Choose the right tools
Build smarter systems
Avoid confusion
Stay relevant in AI-driven development

Because today:

👉 Developers are not just coding
👉 They are building intelligent systems

🚀 Final Thought

Not everything is AI.

Not every AI is an agent.

Not every system needs intelligence.

👉 The real skill is knowing what to use, where.

And that’s what makes a smart developer in 2026 💙

This Game Looks Simple… But It Will Break Your Brain in Seconds 🧠⚡

Md Mijanur Molla — Tue, 05 May 2026 07:04:58 +0000

Let’s try something.

You see a challenge.

You think: “Easy.”

You start solving…

…and suddenly your brain goes:

👉 “Wait… what just happened?” 🤯

That’s exactly the kind of problem I built.

🎮 The Challenge

This is not just another coding problem.

It’s a logic + thinking + reaction challenge where:

You must understand hidden patterns
Avoid obvious assumptions
Think one step deeper than usual

Because…

👉 The first answer you think of is usually wrong.

🧠 Why This Is Interesting

Most problems test:

Syntax
Algorithms
Memory

But this one tests:

👉 How you think under confusion

And that’s a completely different skill.

⚠️ The Trap

Here’s what happens:

• You see a pattern → you trust it

• You try a solution → it almost works

• Then something breaks

That’s the trap.

Because:

👉 The logic is not where you expect it to be

🤯 What This Actually Tests

This challenge is designed to test:

• Logical reasoning

• Pattern recognition

• Attention to detail

• Ability to question assumptions

And honestly…

👉 That’s what real-world debugging feels like
