As the question suggests I would like to know what all the differences in the way unix systems and windows systems see and format paths. I write a lot of code that needs to run on both platforms and problems with paths crop up often. Just out of interest I am also planning on writing my own converter.
I realize this question: Difference between windows and unix paths exists but its been solved and the focus was solving the dudes actual problem.
This wiki link will help you figure out the differences: https://en.wikipedia.org/wiki/PATH_(variable)
In short the Paths on both Unix and Windows are used for locating executables with two notable difference among these two:
Superuser on Unix systems don't add current directory as a rule, this is as mentioned to stop accidental execution of commands from current directory.
On Windows some graphical programs don't show up on command line as they are supposed to be run from a GUI.

I tried simpless, but is not supported now for linux. I tried with wine, and later another alternatives. I don't want to type: lessc file.less > file.less each time I modify a file.
Any good compiler, confortable, automatically, for less CSS?
What is the linux tool that has same functionality as WinLESS i.e. that compiles less files whenever they change taking into account which less files include which?
The most obvious way is to run the javascript implementation on Node.
For Ubuntu, start by installing nodejs and npm, then see e.g. these instructions for compiling LESS to CSS with Node. You should get it going with something like
npm install -g less
lessc mystyle.less

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 was just wanting to go ahead and make an OS. Because working on projects makes one's knowledge quite good enough. I know I will have to study OS inside-out before actually trying to implement one on my own. I also know I wouldn't be able to implement something right from square one. So I searched the internet for something to work upon. The most common option that I found was to work upon existing Linux distro and contribute to it.
But I found some more interesting options. Would like your suggestions on what to choose for and work upon.

PintOS: http://www.scs.stanford.edu/10wi-cs140/pintos/pintos_1.html#SEC1
Cosmos: http://www.gocosmos.org/index.en.aspx
I would get around 6 months time to work upon it. But before I start off with it, I want to do my research work properly and finalize what and how to work.
Drop in your suggestions on what should I use to work on. :)

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.

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).
