Want to create a Gist from your editor, the command line, or the Services menu? Here's how.
function encrypt(text){ | |
var cipher = crypto.createCipher('aes-256-cbc','d6F3Efeq') | |
var crypted = cipher.update(text,'utf8','hex') | |
crypted += cipher.final('hex'); | |
return crypted; | |
} | |
function decrypt(text){ | |
var decipher = crypto.createDecipher('aes-256-cbc','d6F3Efeq') | |
var dec = decipher.update(text,'hex','utf8') |
When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:
const Article = require('../../../../app/models/article');
Those suck for maintenance and they're ugly.
When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com
, example2.com
, and example1.com/images
on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers

-
brew install gnupg, pinentry-mac
(this includes gpg-agent and pinentry) -
Generate a key:
$ gpg --gen-key
-
Take the defaults. Whatevs

Tell gpg-agent to use pinentry-mac:
$ vim ~/.gnupg/gpg-agent.conf
