Allow Docker Container Access to Host's Postgres Database on linux (ubuntu)

You have to do 2 things in order to allow your container to access your host's postgresql database

  1. Make your postgresql listen to an external ip address
  2. Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Make your postgresql listen to an external ip address

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf

Chrome/Gmail attack received 11/03/2016. Not sure if the Chrome meta refresh + data:text,html technique is novel.

The following attack will display a "you've been signed out" page for GMail, and attempt to steal your account credentials.

DO NOT PUT ANY ACCOUNT CREDENTIALS INTO ANY TABS CREATED AFTER VISITING THESE LINKS :)

I received an email in my GMail inbox with a fake attachment image, styled to look like the real GMail attachment UI:

fake

This linked to a page that ended up displaying a fake "you've been signed out" link, via the data:text/html... URL feature of Chrome:

Using multiple github accounts with ssh keys

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

  1. Generate ssh key pairs for accounts and add them to GitHub accounts.

Using react-motion with react-router

/**
* One example of using react-motion (0.3.0) within react-router (v1.0.0-rc3).

* Usage is simple, and really only requires two things–both of which are
