When somebody asks me about how strong you are in unix/linux internals ? What do they really mean ?
Though i have some idea, i would like to hear from some experts that, what is really meant by unix/linux internals.
My ideas are, i have to be strong in,
linux boot process
user creation
how does a command executes
filesystem related details
process details
I would like to know, whether this is sufficient or something else there ?
Update: I edited this question to add more details, if possible reopen the questions for answers?!
The internal design of the components of the Linux operating system (i.e. the kernel).

I know that I need to know at least C and Assembly. In your own opinion what else does one need to know apart from knowing how to program in C and Assembly efficiently? Are there any books you can suggest to get me started? I also read that you need to know about the hardware architecture of the platform you are emulating. Would you also recommend the books listed here?
For experts only
You would have to know all the inner workings and hardware details of PSP, which are business secrets of Sony and therefore not published. The way most emulators are made is reverse engineering, a process in which the device itself is disassembled and its inner workings are studied. That includes analyzing the chips thoroughly, reading the contents of ROM chips and sometimes even deciphering encrypted data. Full analysis usually requires specialized equipment and years of engineering experience.

Due to security requirements, I need to keep a log file of whenever any file on the system is read or written. The log file would look like this:
file - time - user
How would this be done?
See if auditd works for you - http://linux.die.net/man/8/auditd
You could also consider using inotify

I am using the extension library addressbook dialog. The search is pretty horrible for a large company like ours. Is there a better addressbook dialog out there? I'd like to avoid writing my own right now.
Bruce you might need to code it yourself. It seems development doesn't see a need for being mores creative or they feel enhanced dialogues are to specific. Check this idea for inspiration.

I want to write a simple applet to put in a tray. Let's say it will be for gnome taskbar or tint2. My applet should show system temperature or any other simple information by probing at a fixed amount of time /proc or maybe providing this info by clicking on the applet itself, I still have not decided.
My knowledge is limited, since I don't know where to start. What I need is some little info, on the difficulty of the matter, provided I'm fairly ok with bash, but that's it.
Where do I start and what should I read first? There should be gui, then is it gtk, qt or something else? Maybe somebody got a good link or just your opinion will be a good start for me.
Assuming you mean GNOME 2, you could start reading the document Gnome applets with Python. You will get the idea behind applets and how to do it with Python. For tin2 the API might be totally different.

I want to write a program in Linux which by getting a session id could print all processes and process groups in that session in a tree view structure!?
How can I extract such information!? Should I resort to proc file system?
Most (all?) Linux programs read /proc to know about running processes.
If you are using Perl, then may be Proc::ProcessTable cpan module may save you some work.
Edit: Since you are using C, then you can look at pstree source code to get inspiration.
