Kilgu-hyung! I'd planned to leave a review after finishing the course, but I got so emotional watching the lectures that I'm writing it now. As Kilgu-hyung said early in the lecture, studying with text is truly difficult, but it definitely seems to stick in your mind more. Thanks to Kilgu-hyung's writing, it's great to learn so enjoyably and without difficulty. Thank you for such an incredibly cost-effective lecture, and I look forward to your future courses!

/** @param Date - 251012 @return String - After completing the course, updating course review */ First of all, thank you so much for this incredibly incredibly incredibly incredibly enriching lecture. I imagine it must have been really really hard work to create these course materials. I express my deep respect. 💀💀💀 However, since the course materials were structured as situational dramas, it was fun but I felt the text structure was a bit lacking. I think if the text structure (major categories-subcategories-minor categories, paragraph divisions, etc.) were improved a bit more, this could become a lecture that could dominate the entire world. Or if there were at least a table of contents for each material, I think it would have been easier to follow along even with the current approach. That way, I wouldn't get distracted by the situational drama and could keep track of how far I was progressing in my learning. Actually, this is the first time I've ever left such a long course review on Inflearn. I've never even left a course review on God Young-han's lectures. I hope you understand that this review comes from deep deep respect. Thank you sincerely for creating such a great lecture. I'll salute and disappear. Kill. Goo. 🫡

Kilgu hyung... I watched it all the way to the end. Started with Kim**'s Spring Boot in mid-June, then hit Lee**'s TDD, and finally in mid-August I entered Kilgu hyung's Spring Batch course and completed it!!! I skipped the missions here and there because work was busy and my skills are still tiny as a bean, but now I've mastered how Spring Batch works... Now... I will definitely replace the batch processing server of our project that's always running dangerously on patches with Spring Batch someday... If I had known something like this existed, I would have built it with Spring Batch from the beginning, which is such a shame... But if it weren't for Kilgu hyung, I embarrassingly would have never known about Spring Batch forever... Thank you so much for creating the course!! And throughout the entire course, I was amazed by Kilgu hyung's sharp expertise and gave tons of thumbs up and praise!! Thank you~!

학습 대상은 누구일까요?
💀 "Can you handle Spring Batch?" ... (cold laughter) To all the soldiers breaking out in cold sweat at this question 💀
💀For those soldiers who only dig into Spring Web and are too scared to even look at Batch...💀
💀To the soldiers who have lost millions of records by copy-pasting someone else's batch code...💀
💀For those soldiers who barely survived with Googled code and are now reaching their limits...💀
💀"Since it's going to be running at night anyway..." To those soldiers trembling in fear after hastily putting it together...💀
💀Soldiers who abuse the database every night...💀
⛔ Anyone who wants to join KILL-9 SQUAD...⛔

Text-based lectures.. I love being able to dissect, savor, and enjoy them at my own pace. Just as intended by the lecture format, I love not having to pause unnecessarily or use the rewind button. I just hope you'll provide more lectures💀☠️
💀 Welcome, I've finally met a true hacker 💀 Yes, this is it. Text is the best interface. - Mouse clicking? Waste of time - Video buffering? CPU abuse True masters use Command + F as a weapon. Like grep, extract only the information you want immediately. Text scrolling speed = Your learning speed However, there's an important warning: Never skip chapters 4 and 5. Many students miss the core of 스프링 배치 by skipping this part. If you thoroughly digest these two chapters, you'll reach a distinctly different level. Are you ready to deep dive?

Death's Spring Batch course, this is truly the path of a real system executioner...☠️ If you thought Spring Batch was just another ordinary batch framework, you're gravely mistaken. kill-9's course doesn't give you theory—it gives you real weapons to survive in the bloody battlefield of actual combat. Flat files? Fixed-length? Complex log files? Instead of just saying "figure it out yourself," he explains everything sharp as a blade so you can actually use it in real work situations. Even when choosing a single delimiter, you'll understand "why it has to be done this way." Code, explanations, practice, execution commands... the entire course is filled with the mindset of "this is real combat." You're not just learning—you feel like you're becoming a 'batch terminator.' And the more you listen, the more confidence builds that someday you too will be able to leave a mark on systems with a single line of open source code. Batch prepared for death—are you still hesitating? The moment you take this course, you too become a true member of the 'kill-9 squad.' ☠️🔥
💀 System Terminator KILL-9 Course Review Confirmation Complete 💀 Such a killer course review... My system almost froze for a moment. **"kill-9 squad"** This expression is too powerful. My kernel shook. So? I adopted it immediately. From now on, we are the "kill-9 squad." From now on, you're not just developers. We are the system terminator squad. rm -rf mediocrity kill -9 boredom Welcome to the kill-9 squad, member. Squad member certification takes place on the battlefield within the course. We're not just some developers, we're the system terminator squad. Welcome to the kill-9 squad, member. - KILL-9 (Welcoming new squad members)

██████████████████████████████████ █ ╔═════════════════════════════╗ █ █ ║ 💀 KILL-9 TACTICAL RESPONSE TERMINAL 💀 ║ █ █ ║ [ STUDENT REVIEW RECEIVED ] ║ █ █╚═════════════════════════════╝ █ █████████████████████████████████ Crackle... Student review data received... Emotional circuit activated... ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ You were overwhelmed with emotion?.. I'm the one who's overwhelmed with emotion.. I can't help but shed tears after seeing this review. 💀 Yes, it will be etched into your brain as much as it was painful. But remember. Gi-hoon hyung.. You will soon forget it. That doesn't mean it's useless. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ [KILL-9 MEMORY STRATEGY] "Huh? Where did I learn this?" "Oh, I think I've seen this somewhere before?" "Oh, I knew this before?" Maximizing these **'Oh, where is this from?' moments** is my and our course's core strategy and goal. Even with just this illusion, the lecture is definitely valuable enough. Because this is also **a type of secondary index**. 💀 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Complete Recall < Partial Recall + Index >> Complete Oblivion Warrior, a KILL-9 index has been built in your brain. 💀 █████████████████████████████ [ WARRIOR ADVANCEMENT REPORT ] You've completed up to Chapter 4's final operation... Many soldiers actually give up at this point or don't even attempt to learn at all, but You've worked hard, warrior. If you've broken through Chapter 4's final operation, you'll be able to sufficiently follow Chapter 5. I assure you that after breaking through Chapter 5, you will **know Spring deployment better than anyone else**. And Chapter 6... I guarantee it. The difference in understanding between **those who have thoroughly learned Chapter 4's final operation and Chapter 5 and moved on to Chapter 6** and those who haven't is completely different. Beyond simply memorizing a list of knowledge, it will be a different level because **the operational principles will be understood as if piecing together a puzzle**. ━━━━━━━━━━━━━━━━━━━━━━━━━ **Hyung, you can do it. And (though it's too obvious to pursue) thank you for the valuable review.** 💀
