30日でできる! OS自作入門
Some self-talking
This serial should have been written in japanese, since the book has a japanese author. However, due to my laziness, I do not grasp the language, so the language of computer —- English, will be used instead.
I know the book is newbie oriented, I may not learn much from it. The knowledge may be trivial, but I still want to get some hand-on experience with writing Operating System.

After reading
- Too many highly customized tools !
- If you are person who would like to figure out how things work rather than be told “Just believe me, do this and it works”, Don’t read this book !!! (from my own perspective)
- wiki.osdev.org is a better place for “learning” OS dev rather then “seeing” OS dev. The author of the book is undubitably a powerful and sophisticated programmer, but he decide this book to be noob-oriented ……
- And after reading Beginner Mistakes on osdev, I understand a bit more about why I feel uncomfortable reading the book. The book is trying to introduce a very very difficult topic to completely noobs and make it understandable. So it is just impossible for author to explain every thing in detail.
- If you want to learn OS, it maybe, just maybe easier to get start with LFS. Dig deeper into source code after having a higher level of view may do some good.
