1. Get node binary (node.exe) from http://nodejs.org/download/
2. Create the folder where node will reside and move node.exe to it
3. Download the last zip version of npm from http://nodejs.org/dist/npm
4. Unpack the zip inside the node folder
5. Download the last tgz version of npm from http://nodejs.org/dist/npm
6. Open the tgz file and unpack only the file bin/npm (without extension) directly on the node folder.
7. Add the the node folder and the packages/bin folder to PATH
8. On a command prompt execute npm install -g npm to update npm to the latest version

Now you can use npm and node from windows cmd or from bash shell like Git Bash of msysgit.

# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName

#GNU Screen Cheat Sheet

##Basics

• ctrl a c -> cre­ate new win­dow
• ctrl a A -> set win­dow name
• ctrl a w -> show all win­dow
• ctrl a 1|2|3|… -> switch to win­dow n
• ctrl a " -> choose win­dow
• ctrl a ctrl a -> switch between win­dow
• ctrl a d -> detach win­dow

// Simple example, but the idea holds for more complex objects.


/* 1) Start with OO */

// user.js
class User {

    this.firstName = firstName
    this.lastName = lastName

// Finally wrapped your head around Promises? Time to toss out all that knowledge and learn the functional alternative!

// Here's a super simple implementation of a Task "type" 
const __Task = fork => ({fork})

// Absurdly simple! All we're doing is using a function that returns some unknown value, by name, in an object. 
// At this point "fork" is just a cute name though: what matters is how we use it.
// What makes Task a "Task" is that is that the "fork" value here... will be a higher-order function.

// Here's a usage example, already fully functional, already nearly as powerful as Promise!
