##How To Reset Your Github Fork

Let’s say I want to contribute to a project on github. The project repository is at wp-cli/wp-cli. First I fork it, and then clone the resulting repository, scribu/wp-cli:

git clone --recursive git@github.com:scribu/wp-cli.git
cd wp-cli

Now, I make some commits to master, push them to my fork and open a pull request. Piece of cake:

git commit -m "awesome new feature"

##O que fazer quando o vagrant perde a referência da VM

Normalmente, quando o Vagrant perde a referência a uma máquina virtual, ele cria uma segunda máquina e começa a utilizar esta.

A solução fica fácil: simplesmente remova o disco virtual da nova máquina e configure para apontar para o disco da máquina anterior.

The trick was to open the Command Prompt as administrator and start the Device Manager from the same command prompt.

1. Right-click “Command Prompt” in Accessories and choose “Run as Administrator”
2. Enter “set devmgr_show_nonpresent_devices=1″ – without the quotes obviously
3. Enter “start devmgmt.msc”
4. In the box that opens, select “Show hidden devices” in the ‘view’ menu.

Now if you expand the section on COM ports, all the COM ports that have ever
been created will be displayed, the non present ones being in grey. You can
uninstall away anything that you don’t want (right click, select uninstall).
