How to run a GUI application as a different user:

Suppose you are logged into your Linux box as user1 using some X window system already (with GNOME/Unity/..). Now you want to run some gui app as another user, user2.

Run:

1. xhost + - Run as the user1. This enables access to user1's X window system from other users. You should see following output: 'access control disabled, clients can connect from any host'
2. sudo su - user2 - Using your favorite terminal, log-in to second user.
3. export DISPLAY=:0.0 - optional for some apps.

TypeScript supports Pick to allow you to get a "subset" object type of a given type, but there is no built-in Pick for deeper nested fields.

If you have a function that takes a large object as argument, but you don't use all of its fields, you can use Pick, Pick2, Pick3, etc to narrow down the input type to be only just what you need. This will make it easier to test your function, because when mocking the input object, you don't need to pass all fields of the "large" object.

HOW-TO enable MarkDown support in RobotFramework

You want to execute robot test which are inside fenced code blocks of a markdown file (.md) like any normal robot test? Follow the steps below then you can run your tests as simple as robot your_test_suite.md with all robot command line execution options.

This will add support for .md files to RF

1. Clone [RobotFramework][4] repository
2. Save the code below as 'mdreader.py' in parsing folder of your local clone. It's based on [restreader.py][1]
3. Add this from .mdreader import MarkDownReader [here][2] to your local clone.
