Some basics for Indian companies

0 comments
It's quite obvious that when you have large customer base, it's difficult to manage it. But the same large customer base is what feeds you and your employees. 'Customer first' shouldn't be just a punchline, cutomers should feel it. When you launch a service or product, the care should be taken to minimise the complaints and at least the commonsense errors from service/product should be removed. "We value our customer and we will look in to matter soon...." is not the proper way. And if you don't care about proper way or the customer satisfaction, at least you must care about your revenues and existence!

The recent airtel (many other service providers) document verification might have cost customers at least one corore (approximate) and that too just because of the miscommunication and wrong ways of administering the things.
They should improve!

GIT installation on ubuntu basics

0 comments
GIT is a free & open source, distributed version control system and it is identified as the most fast version control system in comparison to the other VCS like SVN. Also git is distributed and so you can use it off-line  also. 'Distributed' here turns out to be every development machine being a git repository of it's own. So you have to install git on every development machine.

I haven't used SVN or other system before so don't exactly know how they work but for git the basic things you do is:
Start a Project
initiate the git for it
write your code
add those files to git
Commit 
Write comment for 'this' commit
and the changes are deposited on local/'your development machine'. Now you have to 'push' those changes  to another repository i.e. another server in case you are doing it on multiple machines

Installation of git on Ubuntu (9.04):
It can be done through 'apt-get install git-core' but that installs the older version. The current version is 1.7.2.3. So download it and install as described below:

Steps:
1. Download git from http://kernel.org/pub/software/scm/git/git-1.7.2.3.tar.gz
2. Unzip the above download
3. cd to unziped directory
4. do
sudo ./configure
Will probably happen successfully :)
5. then do 
sudo make
This should o/p the lines below :)

    CC fast-import.o
    CC abspath.o
    CC advice.o
    CC alias.o
    CC alloc.o
    CC archive.o
    CC archive-tar.o
    CC archive-zip.o
    CC attr.o
    CC base85.o
....
....
...


This shows everything is okay,
if that is not the O/p follow the suggestion given by the installation script might be something is missing probably, xlib1g-dev, do it as below 

sudo apt-get install zlib1g-dev
And redo
sudo make

6. then do
 sudo make install
Some thing like
    INSTALL 644 tclIndex
    INSTALL 644 about.tcl
    INSTALL 644 blame.tcl
    INSTALL 644 branch_checkout.tcl
    INSTALL 644 branch_create.tcl
    INSTALL 644 branch_delete.tcl
    INSTALL 644 branch_rename.tcl
    INSTALL 644 branch.tcl
    INSTALL 644 browser.tcl
    INSTALL 644 checkout_op.tcl
    INSTALL 644 choose_font.tcl
    INSTALL 644 choose_repository.tcl
    INSTALL 644 choose_rev.tcl

shows you have to relax now, git is successfully being installed..

And that's it.

Using GIT:

1) Now create a project or go to your project directory  Ex. mkdir newpro and CD newpro and write your file now or those might already be present if it's old project
2) do initiate the git for it by  git init
3) add all the files from project to  git i.e. by git add .
4) and now commit the changes or in new project case initial commit by git commit
 you will be taken to a file where you can enter a comment so that you remember what was the reason for commit, like in this case we can say "Initial commit"
Then our git repository is perfectly ready.

Now you are free to do changes to  your files and save them as we usually do.
Now add the changed files to git by
git add nameofchnagedfile
and then commit
git commit

other typical uses are well documented here: http://www.spheredev.org/wiki/Git_for_the_lazy , http://www.kernel.org/pub/software/scm/git/docs/user-manual.html#manipulating-branches ,   and one can be more comfortable  with them as he start using it.

To do it on different machines say m1 and m2, first we install git on both machines. Say m1 is central repository and initially our project is there, what we do is initiate git for that project (on m1) and get a clone of it as below (described here: http://danielmiessler.com/blog/using-git-to-maintain-your-website)

cd newpro
git init
git add .
git commit


and then come out of our directory i.e

cd ..
and then clone it
git clone newpro/  newpro.git

so the repository clone is ready on m1

now let's go to m2 and get the clone there and work on it and as you do changes push them to m1 and pull the recent code from the same. Haven't tried this yet, will post it times later.
