+It's almost my graduation.
+Hence, something need to be noted for my whole Ph.D. period.
+I planned to start this writing when I was first notified of the acceptance of the second paper.
+Same location, 4 years passed.
+    
+It was the first time I had a first author publication and it all came at the second months I formally start my program.
+You can imagine how much graceful when I heard the news.
+However, after that, time froze.
+And the consequence is no more throughput in the later 4 years.

+This will be a series regarding lab I gave during the spring 2022 semester.
+  
+The reason why I am writing this down is because it has been a week and no students ask for the solution of the last Lab.
+I realise that learning gap between students are huge, especially when a non-profit university is admitting more and more students.
+To help all students in understanding concepts of modern OS, I decided to write this post.
+  
+It starts with the past lab content I have (as the skelton), and will be amended with extra materials I think it helps.
+Remember, it's for helping in learning. DON'T COPY & PASTE CODE!
