Information
Welcome to the second iteration of the previous "jvm-manual".
I have decided to rewrite it due to it's previous format being very glued together and in general it not going very in-depth into certain concepts.
The entire point of the manual has always been to explain these concepts in a way where they are very simple to understand, because in my opinion learning from things like academic papers is hard and the layout of the information is always weird as well as the language used is often over-complicated for no reason.
I believe a lot of the concepts can be explained in a more simple fashion or in other words where even the most high-grade dummy can understand.
I have always been bad at taking information in and the way academic papers are usually constructed never helped with that, so this is for the people that have a similar problem.
This time I want to expand on the previously explained concepts as well as explore some non-JVM reverse engineering.
That means this will also include native RE (x86_64 mainly).
I will try to go more in-depth with the concepts I have previously documented but as always I am just one person and updates might take a long time so contributions are always welcome and would help a lot.
The original iteration of the manual saw a decent amount of attention from people and was pretty successful which is why I am continuing it. My main goal which I said before is ease of understanding has also been mostly achieved as I've seen a lot of readers say it is easy to understand and very straight-forward.
Now that I'm done yapping away you may continue reading. I hope you enjoy it and I hope it helps on your journey.
