Git newbie: Fatal : Cannot use user as an exclude file

So I started using Github. Since everyone is using it I thought, well just go ahead and use it. Should not be that hard right? Oh well, I guess people forgot to mention that you will loose some hair first before you can upload things - specially if it is related to iphone / xcode.

So after initial git commit etc, I have happily created a new xcode and tried to upload. Terminal says, sorry cant upload some items. So I Googled and found that you got to put .gitignore for iphone / xcode things.

But the problem is, I dont know where to add the ignore file. And to make it worse, I have NO IDEA how to create it. After many many search I found, to create - I got to use

nano .gitignore

And vola, now I can create a gitignore file. So I added those and saved it and then I tried to git it and there you go, a new error popped up.

fatal : cannot use /users/avi/ as an exclude file

I searched high and low what might have caused it. Tried all sorts of command only to find more and more errors. Here are a few : 

1.  fatal: bad revision 'HEAD'

2.

After many many tries, I finally found the solution 

nano ~/.gitconfig

This will bring you to the main config file which has these 

[user]

your user details

[core]

exclude users/avi/

Once I deleted those lines, I could commit and upload it right away. 

fixing repeat export error in imovie or any other i-things

One of the most annoying thing of built in i-things (iphoto, imovie etc) that once you want to do more than what is there, it is very hard. However, what makes it worse is, when you export it and you got it wrong, you just keep getting it wrong.

Yesterday while exporting a video from imovie found the solution - duplicate the project and change the settings in that duplicated project. If you do that, you can export again. Else - oh well!!
