How to create TGZ archive with TAR

First of all: extension *.tar is the as tar.gz

Create tgz Archive with this command:

What is -cvzf:
c - "create" it means you want to create this archive
v - "verbose" if you want to see the process... it shows details about the results of running tar.
z - "zip" it means you want to compress file. tar will use the `compress' program.
f - "filename" it means you  want to name archive with the specific name.

If you want to read the TAR manual in Terminal type in Terminal man tar

Everything was great until I changed workspace in Eclipse for other directory. When I opened th project I've got a bunche of errors "unbound classpath variable m2_repo". In this case do this:

1. Go to Preferences/Java/Build PAth/Classpath Variables

How to login to the new Dynamic view of Blogger

I've changed view of my blog iPaniov.blogspot.com for a new dynamic view which I really like it, but there is no way to login. I spent some time until I understood that this view is for READERS only, so this why there is no login form. So in order to login to your blog on bloodspot.com you should go to the Blogger.com and do login there. Only this way you will be able administrate your blog.

I think there is the lack of clarification about this from the part of Google.
