"Quick Start Chat" to Google Code Hosting for newbies {#qsc #google}

Hi, I normally avoid chatting on Linux topic. and I hate when someone ask his/her problem on chat. I hate because It is one to one communication. I redirect such newbies to mailing list so that other can participate into it. Google index mailing list thread so that other can read such thread after google search. But I found one useful thing in one to one chat system. one of one chat system can be useful for guiding the procedure to newbies.
Today when Abhishek Indoria (A 14 year old school boy, OLPC contributor) asked me how he can put his source code to some hosting site, I immediately got idea of "Quick Start Chat". In this system I have explained him each and every steps and he followed all steps. I always wanted to make a tutorial on how to get started with google code hosting but now I have spent 2-3 hour teaching on chat to produce "quick start chat". You can also blog such "quick start chat" as tutorial.

11:22 AM Abhishek: Dude, I know you may be you know about GIT? or subversion?
11:23 AM me: I have used only svn
but git is something which is better to learn
Abhishek: erm...I need to set up my whole project source code online...
how do I do that?
11:24 AM me: you can do it using sourceforge or Google code hosting
google code hosting use SVG
you can use github too
github use GIT
11:25 AM Abhishek: seems good...But, I need to upload the Source in zip or rar or .tar format instead of editing version like GIT or SVN?
me: no no ,, do not upload tar or zip file
11:26 AM first create a project on these site
and then make a checkout
Abhishek: I have created the project...Checkout?
me: yes,,, checkout the empty project
Abhishek: You know, I feel like stupid as I am only 14 and have loads to learn;)
me: then put your files into it
11:27 AM seee, I learn these things at the age of 24,,,
after making a empty checkout ,, you need to paste files into it
then add files using
11:28 AM svn add filename.cpp
after that you need to comit the files
using "svn ci" command
Abhishek: Ohh..Okay, I am logging into sourceforge...I'll see what I can do, thanks;) Did you read The Lost Symbol by Dan Brown or Code to Zero by Ken Follet?
11:29 AM me: I suggest to use google code hosting,,
I have used it ,, and it has cool features
Abhishek: Erm.. The thing is...
whenever I try Google Code, I can't upload a damn single file.. Dunno why:(
11:30 AM me: Let me guide you,,
Do you have svn installed ??
Abhishek: yup.
11:31 AM I reinstalled Ubuntu yesterday,,, SVN Not installed...
me: ok,, just install svn command,,
it wont take much time
11:32 AM mean while go to google code hosting
and create a new project
Abhishek: okay...

11:33 AM Abhishek: No..but I have already created a project..whats google wave?
11:34 AM me: leave google wave,,, Give me link to google project

4) tag
Abhishek: oh..

11:40 AM just delete it and create new project
Abhishek: okay..
11:43 AM me: Now go to source code and give me the checkout command

never share password
Abhishek: okay.

me: ok,
now create a new file
or you can directly paste your code file here
11:52 AM Abhishek: I have folders too...
