🔥Don't call yourself Dev if you're still doing this.

1. "Write code without comments."

When writing, I thought that I understood it all.

But after three days...

It became the code of strangers in our past. 😭

Remember: Comment = Gift to Yourself in the Future

2. "Solve the code without understanding the problem."

See the bug → the brain refresh in time → "Try if else, add another one."

The last became the premium Spaghetti Code. 🍝

Don't solve problems with feelings. Always understand the cause first.

3. "Do not write tests because you are lazy."

"Let's test it when it's almost done." - This is the speech before Deadline's fall. 🧨

Write a test today. To not cry tomorrow.

4. "Relying on all AI without thinking of yourself."

Type "fix this bug" and paste the entire code.

Definitely through... through the hell of a 🫠 production.

AI helps, but Dev always has to understand what it does first.

5. "No health care."

Sit in the morning and eat coffee instead of water.

Got a lot of commitment, but got a pillow for free.

No matter how good the code is, if Dev doesn't have the strength to live it.

"Good Dev is not measured at the Framework, but at the temple is a problem-time habit."

What are you... still doing?

Read moreการเป็นโปรแกรมเมอร์ที่ดีคือการพัฒนานิสัยและวิธีการทำงานที่ไม่เพียงแต่เน้นโค้ดที่ถูกต้อง แต่ยังพัฒนาคุณภาพชีวิตและการแก้ไขปัญหาอย่างมีประสิทธิภาพ ในบทความนี้ได้กล่าวถึงข้อควรระวัง 5 ข้อสำคัญที่โปรแกรมเมอร์ไทยหลายคนมักทำพลาด ซึ่งมีผลกระทบต่อทั้งการพัฒนาซอฟต์แวร์และสุขภาพในระยะยาว 1. การเขียนโค้ดโดยไม่ใส่คอมเมนต์นั้นเป็นเรื่องที่หลายคนทำในช่วงแรก ๆ เพราะคิดว่าเข้าใจทุกอย่างดีแล้ว แต่หลังจากเวลาผ่านไป 3 วัน หรือมากกว่านั้น โค้ดจะกลายเป็นเหมือนภาษาของคนแปลกหน้าในอดีต ซึ่งคอมเมนต์เปรียบเสมือนของขวัญให้ตัวเองในอนาคต เพราะช่วยลดปริมาณเวลาในการทำความเข้าใจโค้ดเดิม ซึงเป็นการลงทุนเวลาที่คุ้มค่า 2. การแก้ไขบั๊กโดยไม่เข้าใจปัญหาอย่างถ่องแท้นำไปสู่ Spaghetti Code หรือโค้ดที่สลับซับซ้อนจัด การเพิ่มเงื่อนไข if else แบบไม่วางแผนอย่างรอบคอบอาจทำให้ระบบยากต่อการดูแลและแก้ไขในอนาคต สิ่งสำคัญคือการวิเคราะห์สาเหตุของบั๊กอย่างแม่นยำและออกแบบวิธีแก้ไขด้วยความรู้และเหตุผล 3. หลายคนละเลยการเขียน test เพราะรู้สึกขี้เกียจ หรือคิดว่าไว้เทสต์ตอนใกล้เสร็จ แต่นั่นอาจทำให้เจอปัญหาหนักในวันสุดท้ายก่อนกำหนดส่งงาน การเขียนเทสต์ตั้งแต่เนิ่นๆ ช่วยป้องกันข้อผิดพลาด และเพิ่มความมั่นใจในคุณภาพโค้ด ทำให้ไม่ต้องเสียเวลามานั่งแก้โค้ดรื้อหลังจากนั้น 4. ในยุค AI ที่ช่วยได้มาก ก็ยังมีข้อควรระวัง คือการพึ่งพา AI โดยไม่เข้าใจโค้ดที่ได้มา การที่จะใช้ AI ให้เป็นประโยชน์สูงสุด Dev ต้องเข้าใจสิ่งที่ AI สร้าง หรือแก้ไขให้ลึกซึ้งก่อนนำไปใช้ เพื่อป้องกันข้อผิดพลาดในระบบจริงที่อาจส่งผลร้ายแรง 5. สุขภาพของโปรแกรมเมอร์เป็นสิ่งที่หลายคนมองข้าม นั่งทำงานยันเช้า กินกาแฟแทนน้ำ ส่งผลเสียต่อร่างกาย เช่น หมอนรองกระดูกเสื่อม การรักษาสุขภาพที่ดีถือเป็นการลงทุนที่ไม่ควรมองข้าม เพราะการมีสมองและร่างกายที่แข็งแรงเป็นพื้นฐานสำคัญของการพัฒนาที่ยั่งยืนและต่อเนื่อง สุดท้ายแล้ว การเป็น "Dev ที่ดี" ไม่ได้ขึ้นอยู่กับว่าใช้ Framework อะไร หรือเครื่องมือใด แต่ขึ้นอยู่กับนิสัยในการรับมือและแก้ไขปัญหา รวมทั้งความตั้งใจดูแลตัวเองและพัฒนาความรู้ไปพร้อมกัน หากคุณยังทำข้อผิดพลาดข้างต้นอยู่ ลองย้อนกลับไปแก้ไขเพื่อก้าวสู่การเป็นนักพัฒนาที่ประสบความสำเร็จและมีสุขภาพดีไปพร้อมกัน

Your Money Is Useless If You’re Not Doing This
