• user:mine or user:me (or any user id) returns only your posts (or only the posts from whichever user whose id you entered)
• infavorites:mine (or any user id) returns only questions that you (or the user whose id you entered) have favorited.
• intags:mine returns only posts that appear in tags you have marked as favorite. (If you don't have any tags, this operator does nothing. For better results, update your preferences.)

HTTP

• get the HTTP header
• wget -S http://www.cnn.com

github

• git config --global user.email "whatever@yahoo.com"   (your github email, used to identified the committer)
• git config --global user.name "blah blah"
• git add toto.txt
• git commit -am"my test"
• git push

• to see commit graph
• "insight" / "network"

• [old way] About keys: generate keys on each machine from which you want to clone, and add them in gitlab

ssh-keygen -t rsa -C "an.lfl@sony.com"
cat ~/.ssh/id_rsa.pub
add the output of the cat as a new machine key in gitlab in: gitlab.leguide.com/profile/keys 

then you will need to do this on the client machine:
l@al:~/l/catalogs$ git config --global user.email "toto@toto.com"
l@al:~/l/catalogs$ git config --global user.name "Bob Doe"

l@al:~/l/catalogs$ git config  -l       (to check what's in)
