virgenherrera / function stringWeight
Created September 12, 2017 23:13
this function receives a string, encoding, and decimals; and returns the weight if that string in bytes
function stringWeight(str,encoding,decimals) {
var bytes = Buffer.byteLength( str , encoding || 'utf8' );
if(bytes == 0) return '0 Bytes';
var k = 1024,
dm = decimals || 2,
sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'],
i = Math.floor(Math.log(bytes) / Math.log(k));
return parseFloat((bytes / Math.pow(k, i)).toFixed(dm)) + ' ' + sizes[i];

my git workflow, and easy but usefull tricks
#common workflow
clone, make branch, commit, return to origin branch, pull, rebase and push.
#For a list of files to be pushed (between git commit and git push)
git diff --stat --cached origin/master
