💾 A Complete Comparison of cPanel Backup vs WordPress Backup – Which One is Right for Your Site?

2026년 02월 16일 by 노퇴근

When running a WordPress site, you've probably wondered at least once: "What happens
to my data if the server goes down?" "When switching
hosts, can I transfer all my settings and posts intact?"

This is precisely when you need a backup.
But there's one thing that can be confusing here.

It's the difference between cPanel backups and WordPress backups.

Today, we'll clearly distinguish these two backup methods and outline when to use each, focusing on practical applications.

1️⃣ cPanel Backup vs WordPress Backup Comparison Chart

Category	cPanel Backup	WordPress Backup
Execution Location	Server management tool (cPanel)	WordPress Admin Page
Permissions	Full Server Access (Files, DB, Email, etc.)	Access to WordPress internal data only
Included Scope	✅ WordPress files + ✅ DB + ✅ Email + ✅ DNS settings + ✅ SSL	✅ WordPress files + ✅ DB (only certain settings)
Restore Method	Execute "Restore Full Backup" in cPanel	Restore using the plugin's Restore button
Applicable Hosting	cPanel-based hosting (Gabia, Cafe24, Bluehost, etc.)	All WordPress sites
File Format	.tar.gz (server-wide compressed archive)	.zip or .wpress (plugin-only)

In other words, cPanel backups are full server copies, while WordPress backups are site content-focused copies.

2️⃣ To summarize for easy understanding

Many people think, "Isn't backing up just WordPress enough?" But in reality, a site isn't composed solely of WordPress.

🖥 cPanel Backup: Full server replica (includes FTP, email, DNS, SSL)
🌐 WordPress Backup: Content-focused copy (Focuses on files + database)

WordPress is like the 'furniture inside the house,' while cPanel is the 'entire house' that holds that furniture. So, if you only back up WordPress, you might end up with just the furniture left behind while the house is gone.

cPanel backup handles everything at once—including invisible settings like email, secure server (SSL), FTP accounts, and domain connection info (DNS)—making it ideal for "moving your site and server 100% as-is."

In other words, on hosting with cPanel installed, you can back up the entire server. To back up WordPress themes, posts, pages, etc., you use a WordPress plugin instead.

Situation	Which backup should I use?	Reason
Full Site Migration (Hosting Change)	✅ cPanel Full Backup	Allows transferring all server settings and data as-is
Lightweight storage of posts and images only	✅ WordPress Plugin Backup	Daily content protection with automatic backups
For frequently updated blogs	✅ Plugin backup + occasional cPanel backup	Prepared for frequent post edits + Ensures overall stability
Prepared for hacking / outages	✅ Periodic cPanel backups	Full environment restoration capability

3️⃣ Features of cPanel Backups

Full server-level copy Includes all server settings—not just WordPress files, but also email, DNS, SSL, etc.
Restores an identical environment If the cPanel environment is the same, you can restore it immediately using 'Restore Full Backup'.
Backup file location Stored in the format /home/username/backup-date.tar.gz.
Not automatic backups You must manually download backups; server cron settings are required for automation.

A cPanel backup is not simply a "WordPress copy";

but rather a full server backup.

Therefore, it serves as the safest and most reliable restoration method during hosting migration or hacking/failure recovery.

For example, when moving from Gabia to Cafe24, if both are cPanel-based, a single Full Backup file enables complete replication.

4️⃣ Features of WordPress Backup

Plugin-Centric Can be done with various plugins like UpdraftPlus, Duplicator, All-in-One WP Migration
Only files + DB are backed up; server settings, email, and SSL are not included
Automatic Scheduling Supported: Plugins allow setting automatic backups at regular intervals
Simple restoration: Restore instantly with a single button click

WordPress backup works on all hosting environments, regardless of server setup.

For example, you can easily restore even in cloud environments like AWS Lightsail, Cloudflare Pages, and Vercel.

5️⃣ Recommended Backup Plugins

Plugin	Features	Backup Location
UpdraftPlus	Most popular backup plugin, supports automatic scheduling	Google Drive, Dropbox, FTP
All-in-One WP Migration	One-click full site migration	.wpress file (local or server)
Duplicator	Professional tool for duplication and migration	Local / Remote Server
WPvivid Backup	Free automatic backup + one-click restore	Cloud / Local Storage

Most of these plugins are perfectly usable even in their free versions, while the paid versions support automatic scheduling and cloud upload features.

6️⃣ Which backup should you use?

Situation	Recommended Backup Method
When moving hosting while using cPanel (Gabia, Cafe24, etc.)	✅ cPanel Full Backup
When you only need to clone or migrate a WordPress site	✅ WordPress Plugin Backup
Development / Local Testing Environment	✅ FTP + DB Export in parallel

⚙️ If you want to move the entire server (DB + Email +) as-is → cPanel Backup
🧩 If you only want to safely store content + theme → WordPress backup plugin
☁️ For cloud environments like AWS or Lightsail → Plugin + automated script combination

7️⃣ Conclusion: Tailor Your Backup Strategy to Your Situation

Let's summarize what we've discussed so far very simply.

A cPanel backup is literally "copying and storing the entire server as-is."

The server here is the house where WordPress lives.

Inside it are

WordPress program,
images, files,
email accounts,
domain settings,
and even the security certificate (SSL).

So a cPanel backup is like packing your entire house into moving boxes. If the server crashes, gets hacked, or your site suddenly vanishes, you can restore everything perfectly from that single box.

On the other hand, a WordPress backup is like "packing only the contents inside the house—furniture, notebooks, photo albums—separately."

In other words, it's content-centric.

The posts I wrote,
pages,
images,
themes (site design),
plugin settings, and so on are included here.

While it doesn't cover the entire server, you can manage it directly within WordPress and even set it to automatically back up daily, making it much lighter and simpler to handle. So these two backups aren't competing with each other.

They can be seen as partners who help each other.

cPanel backup acts as the guardian protecting the house (server)
WordPress backups safeguard the life records within (posts, images, design, etc.)

In other words, from a server management perspective: If you're a website development agency, use cPanel backups.

while if you're just running the site yourself, you should use backups via the WordPress plugin.

One protects the big picture, while the other safeguards the details.

Summary

cPanel backup → Entire server copy, only possible on hosting with cPanel
WordPress backup → Content copy, possible on all hosting platforms
Using both together ensures complete restoration and a safety net

Ultimately, backup is the 'power to get back up even when problems arise'.

Just one click now can protect everything later.

The Best Immersion Methods for ADHD Escape: There’s a Time for Focus Bursts

2026년 02월 16일 by 노퇴근

Every time I'd think to myself, "Why can't I focus like this?" I started learning a little about ADHD. Then, on some social media channel, I happened to see a method called "The Best Way to Immerse Yourself" and decided to try it.

Especially for those with ADHD tendencies or easily distracted attention, the word "immersion" might feel like a distant dream. But don't worry. Our brains can transform into immersion monsters if we just get the 'timing' and 'routine' right.

I'm genuinely easily distracted and have ADHD tendencies, so I've always been prone to jumping from one thing to another. But using the optimal immersion method routine chart described in this article has boosted my work efficiency.

I'm amazed that I saw results in just three days of implementation, with a dramatic increase in work efficiency. You can explore the brain science behind it, the execution routines, and how to implement them, all based on my personal experience.

🧬 Brain Science-Based Focus Timing

When are you most focused? While it varies by person, neuroscience strongly emphasizes one point:

The first 3 hours after waking up: "The Golden Time for Immersion"

Professor Andrew Huberman, a renowned neuroscientist at Stanford University, states, "The first 1 to 3 hours after waking are a time when arousal hormones like cortisol and norepinephrine surge, making it a period of high concentration."

What if you fail to utilize this period of heightened focus driven by surging arousal hormones?

Your brain falls into a stimulation addiction loop, becoming even more distracted
SNS → Shorts → Messenger → Staring blankly… = Focus depletion

This situation causes the morning's 3-hour window—the prime time for deep focus—to evaporate. It evaporates.

🛠️ The Ultimate Immersion Routine for ADHD Brains (It really works)

Initially, I thought focusing mornings on daily must-dos (content creation), afternoons on one-off tasks (outsourcing, client consultations), and consistent growth activities (development study, coding, reading) would be too complex. But after creating a routine chart and reviewing it once in the morning and once in the evening, my routine started to solidify within just three days.

I think this could be somewhat effective not just for ADHD, but also for anyone wanting to boost their work efficiency.

My actual routine chart

Time Slot	Things to do	Description	ADHD Brain Care Points
The night before	Write a 3-line plan for tomorrow	Keep it simple, not overly detailed	Complex plans lower execution rates
0-3 hours after waking	Focused work without distractions	Frontal lobe focus peak period🗓️	No phones! Prevent dopamine overload
3 hours later	Cold shower, cleaning, walking, etc. – 'Action Meditation'	Sensory Reorganization + Reawakening	TV and YouTube have no reset effect
Before/after lunch	Boring rest (meditation, nap, zoning out)	Dopamine boost + Brain fatigue recovery	Stimulating content actually causes exhaustion
Afternoon to evening	Short task refocus + wrap up plans	Utilize focus one more time	After meals, reset with light movement

The most crucial elements of the ultimate immersion routine are "organizing tasks the night before" and "executing those tasks in the morning"—whether you can or cannot do this is paramount.

📌 Key: Grind through the tasks you organized the night before immediately after waking up

My current routine:
- Before bed: Plan tomorrow's content in advance and list 3 tasks
- Morning: Produce content
- Afternoon: Outsourced work & content creation if no outsourced work
- Evening: Development, study & reading

Before bed: Plan tomorrow's content creation -> Organize 3 tasks for tomorrow -> Morning: Content creation -> Exercise after creation -> Light meal -> Start afternoon work -> After dinner -> Development, study, reading (used for content creation) -> Briefly plan tomorrow's content + organize 3 tasks

Following this sequence exactly led to a sudden, surprising boost in focus and work efficiency within just 3 days.

Previously, my mind was disorganized, so while writing, I'd end up searching for information, scrolling through threads, or watching Instagram shorts. It was hard to even finish one article or one thread post per day. But following this routine, I could write two articles and two threads in the morning, do development work in the afternoon, and even study development in the evening.

💡 Practical Tips for Deep Focus That an ADHD Brain Loves

ADHD brains are easily distracted, yet capable of intense focus on one thing.

"Lower the starting threshold": If you start by saying "just 5 minutes," you'll go 30 minutes.
"Write tasks as a manual": Decide how to do it to boost execution
"Ban multitasking": When focus is scattered, dopamine reserves go negative
"Practice intentional boredom": Challenge yourself to just sit still while waiting for the bus
"SNS only after lunch": If you burn through all your dopamine in the morning, you're screwed lol

🧠 Flow Routine for Optimized Immersion

1. Design the next day the night before

Why? To avoid wasting the golden morning hours.
How? Before sleeping, jot down just 1-3 'core tasks' you must do. (e.g., write a proposal, draft code, write an article)
Why: Reduces decision fatigue. Allows you to enter a state of immersion immediately in the morning without hesitation.

2. Focus intensely for 1-3 hours immediately after waking

Why? Because your brain is most clear and there are fewer distractions.
Conditions: No checking smartphones, no conversations, no social media/news.
Method: Sit at your desk immediately upon waking and immerse yourself in the 'single task' you set the previous day. Using a timer (e.g., 90 minutes) is recommended.

3. Post-Immersion 'Reboot Routine'

Goal: Physically and mentally reset for the next task.
Example execution routine :
- Cold shower → Simple breakfast → Light cleaning → 20-minute run
- Meditation, stretching, listening to favorite music

⚡ Dopamine Recovery and Focus Maintenance

To sustain focus, consciously deplete → recover → recharge your brain's dopamine through a routine.

1. Take boring breaks

Why? SNS/short-form content is a stimulating dopamine bomb. It doesn't rest your brain; it actually tires it out.
How to practice :
- Close your eyes and do absolutely nothing for 10 minutes
- Sit quietly and gaze out the window, water plants, or do light meditation
- Simple actions like taking a walk, napping, or organizing belongings

2. Stay in the present

Why? Focusing on the present helps your brain break free from dopamine addiction and restore balance.
How?
- Stand quietly without looking at your phone while waiting for the bus or subway
- Stare blankly at your surroundings when arriving somewhere early
- Focus on your breathing / Add 'mindful concentration' to daily routines like washing hands or eating

3. Follow the single-activity principle

No multitasking! → It overstimulates the dopamine system and distracts the brain.
The formula for immersion: Eat only when eating → Talk only when talking → Work only when working → Rest properly when resting

3 Tips to Boost Your Brain's Immersion

"Write down your tasks as a manual": Your brain feels less burdened when you decide "how to do it" in advance.
"Dopamine surges from anticipation, not craving": Immersion finds those who endure boredom.
"If you mess up your morning focus, you can recover with an 'afternoon reboot routine'."

While meditating

The first 2-3 hours after waking = Don't miss the golden time for focus
Review yesterday's mission → Work immediately after waking → Maintain the reboot routine
Turn boring breaks → dopamine reset → into a concentration explosion
No multitasking, focus on single tasks

Immersion is the art of arranging the brain's clearest moments and the body's rhythm with 'appropriate stimulation and rest'. Reduce dopamine, gather focus, awaken the body, and quiet the mind. This is 'the best daily design for immersion'.

Find the right AI model for your work environment: ChatGPT (GPT-4o) vs Claude ai (Claude 4 Sonnet) comparison analysis

2026년 02월 16일 by 노퇴근

I create content to resonate with people's hearts.
That's why when choosing AI, what matters more than simply "Which one is smarter?" is "Does it understand my language and remember the texture of my emotions?"

In other words, I need a tool that "understands my language and remembers the texture of my emotions."

Of course, you might be skeptical about AI remembering emotional nuances. To be precise, AI doesn't directly understand emotions. However, it can 'infer and respond' to emotional undertones through the context and flow of conversation. And this subtle difference makes a huge difference when creating emotional services and content.

🤝 The two AI models most commonly used for writing today are

ChatGPT (GPT-4o) – by OpenAI
Claude (Claude 4 sonnet) – by Anthropic

Both models boast outstanding performance, but they can become entirely different partners depending on the user's philosophy, goals, and workflow.

By understanding the unique characteristics of ChatGPT and Claude, two leading AI models, and strategically
combining them step-by-step in content creation, you can craft content that truly resonates with people's hearts.

✍️ Many people ask:

"Which is smarter, GPT or Claude?"

But the truly important question is this:

"Which AI can follow the flow of my emotions, remember my philosophy, and collaborate to create content that moves a person's heart?"

By understanding the unique characteristics of ChatGPT and Claude and strategically combining them at each stage of the creative process, AI can become a powerful partner that goes beyond a simple tool to create 'content that leaves a lasting impression on people'.

"As an emotion-driven brand & developer,
which AI can remember the flow of my emotions, build brand language
based on my philosophy, and
ultimately co-create content that moves a person's heart?"

That's the question I ask myself. I repeatedly train GPT and Claude on my philosophy, my intent, and my ideas, embedding this context into their learning.

So today, from the perspective of an emotion service developer & creator, I'll explore how combining ChatGPT and Claude strategically can be advantageous for content creation.

💡 Comparison Method

I posed the same question to both models (GPT-4o and Claude 4 Sonnet). As of May 23,
2025, GPT-4o could not compare itself to Claude 4 Sonnet. It appears to only recognize the Sonnet 3 version so far.
Therefore, I created a comparative analysis table based on Claude 4 Sonnet.

First, review the comparison table below, then we'll proceed to discuss strategic usage methods.👇

🔥 ChatGPT vs Claude: Which is better for which tasks?

Tasks where ChatGPT has an advantage

Scenario	Reason and Explanation
Long-term projects, brand language, content series creation	Excels at accumulating context through memory function and maintaining brand consistency
Emotion-based content philosophy/systematization/continuous dialogue	Maintaining consistent creative flow and style
Tasks requiring real-time information	Web search functionality available (depending on plan)
Rapid brainstorming and idea meetings	Immediate responsiveness and creative responses
Draft creation and iterative feedback/revisions	Ability to create fast and flexible feedback loops

Tasks where Claude excels

Situation	Reason and explanation
Thesis, literary analysis, long-form summaries/reviews/conversation analysis	Strength in interpreting and structuring analysis of long texts
Logical review/interpretation of a single lengthy text	Exceptional at analyzing complex sentence structures and emotional flow
Deep philosophical thinking, ethical judgment	Tendency toward insightful and contemplative responses
Meticulous document review and precise analysis	Meticulously examines structure, tone, and emotional trajectory
Content planning with strong philosophical purpose	Emotion-centered yet capable of deepening reflection

🎯 How to Optimize ChatGPT

"Use it like a creative partner with memory"

Build context into prompts for brand consistency
Store creative philosophy using the memory function
Use for instant feedback and iterative refinement

ChatGPT's greatest strength lies in its ability to consistently maintain a brand's philosophy, tone, and language style.

For example, based on the philosophy "Move people's hearts with emotion-driven content," you can repeatedly input this context to ChatGPT and have it generate content using similar sentence structures and tone. When a brand's voice, sentence length, and emotional flow remain consistent, it builds 'your own language'.

ChatGPT's persistent context memory function allows it to reflect your creative philosophy

as if internalized. "I create emotion-based content. I aim to convey 'resonance,' not just 'information.'" By setting this as a memory, you'll receive feedback and suggestions reflecting this philosophy in all subsequent content.

It's most efficient for quickly drafting content and then iteratively revising and polishing it.

Example: "This sentence lacks emotional impact—rewrite it to resonate more," "Rewrite this in Gen Z slang"
→ Enables rapid application, quick reflection, and swift improvement. ChatGPT also excels at summarizing content for series or Reels/Shorts.

🎯 Optimal Use of Claude

Use it "like a deep-thinking content philosopher"

Provide context at the start of every conversation (like your emotion-based content philosophy)
Prioritize it for analyzing complex documents or lengthy texts
When deep thinking or philosophical discussion is needed

Since Claude starts fresh each session, it's best to briefly and powerfully reintroduce your philosophy as an opening statement every time.
Example: "
I am an emotion-based content creator. I want to write pieces that stir people's emotions and leave a lasting impression." With just this
one sentence, Claude will empathize like an expert and provide deep, thoughtful responses.

Claude can analyze long-form writing for overall tone, emotional arc, and logical flow. It's ideal for receiving feedback on
the logic + emotional structure of long blog posts or essay drafts where emotional flow matters.
"Tell me where this piece lacks resonance," "Analyze what emotion readers might feel here" → Claude excels at this.

🤝 How to Use ChatGPT + Claude Hybrid

"Hybrid Flow: Achieving Both Depth and Consistency"

Brand Language Development & Series Expansion with ChatGPT
Mutually Complementary Review: Validate one side's results with the other
Derive deep analysis and insights with Claude

Claude excels at defining content direction, emotional structure, and distilling the philosophical message you want to convey.
Example: "Summarize philosophically why this article is needed," "What is the emotional core of this topic?"

Based on insights Claude provides, ChatGPT excels at refining them to match the brand's tone and expanding them into series content.
Example: "Summarize the core insights Claude mentioned in an emotion-based brand tone."

Draft with Claude
Refine the draft with ChatGPT,
Then request Claude to philosophically review ChatGPT's output

Cross-feedback between the two AIs ensures consistent brand philosophy and tone while elevating content quality.

In conclusion

AI-generated content is abundant, but content that truly resonates with human emotions remains scarce.

We choose AI not merely for "efficiency," but to select a "
colleague who understands our language and emotions and can co-create with us."
ChatGPT and Claude can be 'two lights' walking alongside the journey of emotional creators.

Optimizing the cost of AI training: A step-by-step guide for the early, mid, and long term

2026년 02월 16일 by 노퇴근

After the ChatGPT craze, every developer wants to build an AI model. But the reality? It ends up costing way too much money.

Especially for individual developers or startups:

Cloud: Unpredictable billing bombs 💸
On-premises: Heavy initial investment burden 💰
Just giving up: Falling behind in AI innovation 📉

But is this really the only way? So I've put together a summary.

2025: A New Turning Point in AI Development

1. HuggingFace + AWS combo

I fine-tuned one sentiment analysis model, then nearly had a heart attack seeing the AWS bill the next day

You might set a monthly budget of around 1 million won, but when billing day rolls around, you could get hit with an unexpectedly huge charge.

2. On-Premises vs. Cloud: Reality Check

Is on-premises really the answer? Dell EMC server racks + a knowledge industry center (with low electricity rates) could be far more efficient.

Dell EMC server rack configuration:

4 GPU servers (RTX 4090 x 4 per server)
Total Purchase Cost: 80 million KRW (one-time)
Knowledge Industry Center electricity cost: 500,000 KRW/month

Equivalent performance on AWS p3.8xlarge:

$14.688 per hour (approx. 20,000 KRW)
Assuming 720 hours per month: 14.4 million KRW
Over 170 million won per year 💸

Conclusion: Running it for just 6 months shows that on-premises can be more profitable when viewed as a long-term investment.

3. But the hidden costs of on-premises

bash# 예상 vs 현실
초기구매비: 8,000만원 → 1억 2천만원 (UPS, 쿨링시스템 추가)
전기세: 월 50만원 → 월 120만원 (에어컨 24시간 가동)
관리비: 0원 → 월 200만원 (시스템 관리자 필요)

4. Ultimately, the developer's dilemma

Cloud: Flexible but a cost bomb
On-premises: High upfront costs but profitable long-term?

But the real problem is… both cost a lot of money 😭

5. So the real solution we found: NPU

Neural Processing Unit = AI-dedicated chip

Over 10x more power-efficient than GPUs
High initial cost but long-term benefits
Predictable fixed costs

NPU + Knowledge Industry Center Combination:

Initial: 30-80 million KRW
Monthly operation: 500,000–1,500,000 KRW (electricity + management)
After 6 months: Becomes cheaper than AWS

6/ But the real game changer is this

Pre-trained model + Fine-tuning

Training from scratch ❌ Utilizing existing models ⭕
Reduces development time by 1 year
Saves hundreds of thousands of dollars
Only 100,000-500,000 KRW per month

🧠 AI Training Cost Strategy at a Glance

Strategy	Recommended For	Key Benefits	Emotion-Based Criteria	Budget	Risk
🔹 Pre-trained model + Fine-tuning	Short-term results, MVP launchers	Time + Cost Savings, Flexibility	Suitable for MVP implementation	💸 100,000~500,000 KRW/month	Limited customization
🔹 NPU + On-Premises	Companies building their own AI OS	Lower power costs, reduced long-term expenses, increased independence	Capable of building large-scale architectures	💸 Initial investment: 30–80 million	Initial capital burden
🔹 Small Language Models (sLM)	Personal creators, prototypes	Laptop-compatible, lightweight	Optimal for UX experimentation	💸 0~100,000 KRW	Difficulty with complex logic processing
🔹 Cloud NPU (KT ATOM)	Startups seeking GPU alternatives	Stability↑, Operational Ease	Backend for server processing	💸 300,000~700,000 KRW/month	Dependencies, complex setup

1. Pre-trained models + Fine-tuning (Highly recommended)

Leveraging pre-trained AI models can reduce AI application development time by up to one year and save hundreds of thousands of dollars.

Reference: What Are Pre-trained AI Models? : NVIDIA Blog

Cost: 100,000–500,000 KRW/month

HuggingFace models + AWS/Google Cloud Spot Instances
Fine-tune existing models for specific use cases

2. NPU + On-Premises Combination (Long-Term Optimal)

🚨 What to watch out for when using GitHub (Security – Hacking prevention)

2026년 02월 16일 by 노퇴근

🚨 Important Considerations When Using GitHub (Security and Hacking Prevention)

1. Be cautious with files containing sensitive information

Never upload important information like passwords, API keys (authentication keys), or personal information!
Information uploaded to GitHub can be easily viewed by others.

🪄 Analogy:

It's like leaving your house key in front of your door—anyone can walk right in.

💡 Example solution:

# 잘못된 예 (민감한 정보 직접 포함 ❌)
API_KEY = "123456789abcdef"

# 올바른 예 (별도 파일로 관리 ✅)
.env 파일에 저장 후, .gitignore로 관리

2. Always use the ``.gitignore`` file

Specify files that should not be uploaded to Git to prevent accidental uploads.

🪄 Analogy:

It's like hiding important items in a safe so others can't see them!

💡 Usage Example:

# .gitignore
.env
password.txt
node_modules/
__pycache__/

3. Always verify before committing and pushing

Don't commit or push hastily—always double-check your file contents!

🪄 Analogy:

It's like the habit of rereading a message before sending it to a friend to avoid sending the wrong content!

💡 Good Habit Example:

git status         # 변경된 파일 목록 보기
git diff 파일명    # 파일 내 변경 내용 확인

4. Be especially careful with public repositories

Public repositories are visible to anyone on the internet.
Always store sensitive information in private repositories or manage it separately.

🪄 Analogy:

Wouldn't it be risky to post your personal information on a bulletin board anyone can see?

5. Beware of hacking risks when forking or cloning

When forking or cloning a project created by someone else Forkor Clonemay contain hacking code or malicious code.

🪄 Analogy:

Wouldn't it be risky to just plug a USB drive given by a stranger into your computer?

💡 Prevention method:

Only use official and trustworthy projects.
After downloading code, always verify the file contents!

Points to note when using Git commands (commit, branch, merge, push, pull, etc.)

1. Commit Precautions

Write meaningful commit messages. (This makes it easy to understand what changes were made later!)

Good example ✅

git commit -m "feat(login): 로그인 버튼 추가"

Bad example ❌

git commit -m "수정"

📌 2. Branch Precautions

Do not work directly on the main branch. It's better to work on a separate branch and then merge it.

Example of creating a branch

git checkout -b feat/login-page

🪄 Analogy:

Think of it like drafting (on a separate branch) and then moving it to the original (main branch) once complete!

📌 3. Merge Precautions

Always check for and resolve conflicts before merging.

Example of resolving conflicts

# 브랜치 전환 및 머지
git checkout main
git merge feat/login-page

🪄 Analogy:

Imagine two different people writing on the same note at the same time—you'd need to neatly organize the overlapping content, right?

📌 4. Push Precautions

Always double-check file contents before pushing, and correct any incorrect commits before pushing.

Push Command Example

git push origin main

🪄 Analogy:

Like double-checking before sending an email or message!

📌 5. Pull Precautions

Always update to the latest state before starting work (git pull) to incorporate others' changes.

Pull command example

git pull origin main

🪄 Analogy:

When writing a shared note with a friend, if they added content first, it's best to review their changes before starting your work!

✅ Must-remember one-line summary tip!

Never upload sensitive information to GitHub, and always double-check your file contents! 📌🔐

By carefully following these basic security and precautionary measures, you can use Git and GitHub safely and effectively.

AI Services Go Global, GDPR-CCPA Preparedness in a Nutshell

2026년 02월 16일 by 노퇴근

If you're preparing an AI service, you absolutely cannot overlook international privacy laws, especially GDPR (Europe) and CCPA (California, USA). You might think, "It was made in Korea, so why should I care about foreign laws?" But GDPR and CCPA apply based on the location of the user. In this article, we'll cover the applicability criteria, fines, and preparation strategies for GDPR and CCPA all at once.

💥 Helpful Tip

AI services are governed by the user's location, not the service's country of origin. Even a single user in Europe or the US can make your service subject to GDPR and CCPA.

Problem: Skipping initial preparation leads to skyrocketing development, legal, and marketing costs when fixing issues later.
Solution: Prepare from the start using a GDPR/CCPA readiness checklist. This article covers the essentials, so read it through to the end!

🇺🇸 CCPA (California Consumer Privacy Act)

CCPA is California's personal information protection law, effective since January 2020. It is considered the strongest personal information protection law in the U.S. and is a regulation that companies operating global services must strictly adhere to.

CCPA Application Criteria

Annual revenue of $25 million (approx. 34 billion KRW) or more: Based on global revenue; includes any entity with annual revenue exceeding $25 million, regardless of location (Korea, US, Japan, etc.).
However, final applicability requires meeting one of the following additional conditions:
- Possession of data on 50,000 or more California residents
- Data sales revenue constitutes 50% or more of total revenue

The applicability criteria are: global annual revenue of $25 million (approximately KRW 34 billion) or more, holding data on 50,000 or more California residents, or data sales revenue constituting 50% or more of total revenue. If any one of these applies, the entity is subject to the CCPA.

CCPA Application Example

Korean SaaS company, global revenue $30 million, 50,000 California users → ✅ CCPA applies
Same revenue, 10 California users → ❌ CCPA does not apply

Simply having high revenue isn't enough; the key is the connection to California residents' data. A defining feature of the CCPA is its 'opt-out' approach, granting consumers the right to refuse data sales, access their collection and sharing history, and request deletion.

🌍 GDPR (General Data Protection Regulation, European General Data Protection Regulation)

GDPR is the European Union (EU) and European Economic Area (EEA) personal data protection law implemented since May 2018. It is one of the world's strongest personal data protection regulations, centered on "user consent" and "personal data sovereignty."

GDPR Applicability Criteria

No revenue threshold! What
matters is:
- Services targeting EU/EEA residents
- Providing 'goods or services' within the EU or 'targeting users'

Notably, regardless of revenue scale, GDPR applies unconditionally if EU users utilize your service or if you track user behavior within the EU. For example, an AI app developed in Korea becomes subject to GDPR if European users download and use it.

Korean startup, 1 European sign-up → ✅ GDPR applies
Korean influencer sends DM to 1 EU fan → ✅ GDPR likely applies

It applies if even one European user signs up or their behavior is analyzed. Small startups, even with zero revenue, are subject without exception.

GDPR·CCPA Violation Fines

🌍 GDPR Fines

The reason GDPR is so daunting is the scale of its fines. Violations can incur a maximum fine of 20 million euros (approx. 29 billion KRW) or 4% of global annual revenue, whichever is greater.

Up to €20 million (approx. ₩29 billion)
or 4% of global revenue → whichever is greater
GDPR Fine Example:
- Annual revenue 10 billion KRW → 10 billion × 4% = 400 million → Maximum 400 million KRW fine
- Annual revenue 1 trillion won → 1 trillion × 4% = 40 billion → capped at 20 million euros (29 billion)

Applies equally to small startups and large corporations, with fines increasing exponentially as revenue grows. It particularly guarantees strong user rights like the right to access, delete, and transfer data, as well as the right to be forgotten. Processing data without consent can lead to serious legal risks.

The higher the revenue, the higher the fines.

🇺🇸 CCPA Fines

$2,500 per violation (approx. 3.4 million KRW) → General violations
$7,500 (approx. 10.2 million KRW) for intentional violations
Individual/class action lawsuits possible → Bankruptcy risk if cases accumulate

Approximately 3.4 million won per violation, with intentional violations incurring fines of about 10.2 million won. As individual and class action lawsuits accumulate, the total litigation costs increase exponentially.

CCPA Fine Example:
1,000 instances of personal data breach, intentional violation → 1,000 × $7,500 = $7.5M (approx. 10.2 billion KRW)

Fines range from a maximum of $2,500 (approx. 3.4 million won) per violation to $7,500 (approx. 10.2 million won) for intentional violations. As violations accumulate, they can lead to class action lawsuits, posing significant risk. For example, if 1,000 pieces of personal information are leaked, the total fine could soar to approximately 10.2 billion won if it's an intentional violation.

👉 CCPA is scary because of the 'number of cases', while GDPR is scary because of 'revenue'.

GDPR vs CCPA Key Comparison

Item	GDPR	CCPA
Applicability Criteria	No revenue threshold; applies to EU/EEA users	Global revenue ≥ $25M + Relevance to CA residents required
User Rights	Right to access, delete, and transfer data; right to be forgotten	Right to access, delete, or refuse sale of data
Fines	Up to €20 million or 4% of global revenue (whichever is greater)	$2,500 per violation (general), $7,500 (intentional)
The scary part	The higher the revenue, the bigger the fine bomb	Accumulating violations leads to lawsuits + massive fines

GDPR is scary because it's "user-based, regardless of revenue," while CCPA's scary point is "large corporations + California resident data."

In conclusion

GDPR: Prepare if you have even one European user!
CCPA: Global corporations + California user data, take note!

If violations occur involving tens of thousands of users, fines will be imposed at an unimaginable scale. Preparing early can reduce future risks and costs by 99%.

3 Reasons to Pay Attention to ‘Digital Biology’ as a Key Field for the AI Era
