Cross-Domain requests in Javascript
Too Good
If you are developing a modern web-based application, chances are you:
- Are using javascript on the client side.
- Need to integrate with services that are not completely under your control (or that reside in a different “origin”).
- Have been confronted by this error message in your browser’s console:
XMLHttpRequest cannot load http://external.service/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://my.app' is therefore not allowed access.
Every time I need to integrate a web app with some external service or some server-side API I have no complete control over, I bump into this error. Google has not yet provided me with a concise description of the problem or an overview of alternatives to perform Cross-Domain requests, so this post will serve as a personal future reference.

Renaming a Local GitHub branch and applying the change to its corresponding Remote branch
Hola!!!
So, this is a ‘Tutorialeto’ to help you rename your GitHub branches when suddenly your Program Manager asks you to change the names as per her standards(I know you hate that 😛 ).
git branch -m old_branch new_branch # Rename branch locally
git push origin :old_branch # Delete the old branch
git push --set-upstream origin new_branch # Push the new branch, set local branch to track the new remote
The following commands will help you accomplish the same. Enjoy!
