Running GUI apps locally as root in a non-root session

There are instances when you need to run an X Window application. For me this is often running a terminator instance as root so that I can create tabs and split the window as still be root in each of those terminals.

In order for the root user to be able to connect to the X server you need to provide it with “credentials”. In this case it is on the same box and not over the network so the → Continue reading “Running GUI apps locally as root in a non-root session”

VS Code “Test result not found for:” When Running Tests for a Python Project [SOLVED]

I finally was able to get Visual Studio Code set-up correctly to run and debug unit and integration tests for a Python 3.8 project that I am working on (I’ll add a link to that post here once it is up).

After making some changes to the code and adding a test I got the following error when trying to debug the test:

Test result not found for: ./mylibs/integration_tests/myclient_integration_test.py::MyClientIntegrationTest::test_happy_path

? An odd error message, to be sure.

List the Roles for a User or Service Account in a Specific GCP Project

If you do not have web console permissions to do so, but have the ability to activate a service account that has the viewer permissions or IAM permissons to list IAM roles in a given project, the following is how you can list the roles for a given user or service account.

gcloud projects get-iam-policy <gcp-project\
--filter="bindings.members:<email-address" \
--flatten="bindings[].members" --format="table(bindings.role)"

Compiling Python 3.8.x Under Linux

Yes, I know. 3.8.x? That’s an older version of Python but there are still a number of current applications and libs that require 3.8 as well as a number of distros that still have 3.8 as the most recent easily installable version. With that being said, the following is a quick how to on getting it compiled under both RedHat/CentOS/Almalinux and Debian based systems.

Install Dependencies

This assumes that you already have the “build-essentials” and kernel headers installed on the → Continue reading “Compiling Python 3.8.x Under Linux”

Using fc to Edit and Re-execute Bash Commands

I recently learned about the Bash built-in fc. It is a great tool that enables you to edit and re-execute commands from your bash history.

Oftentimes there is a command in your history that instead of just grepping through the history and then re-executing as-is you’ll want to make a modification or two. With fc you can first edit it in your favorite editor and then when closing the editor fc will execute the command.

For me, vim is my → Continue reading “Using fc to Edit and Re-execute Bash Commands”

Creating a Launch Config in VSCode to Debug a Python Invoke Script

I regularly use Python Invoke and Fabric for the automation of various tasks; from deploying code to developing my own set of tools for various projects. Following is an example on how to write a launch.json launch configuration for vscode so that you can step through the tasks.py code and debug it.

Assuming that you have created a virtual environment and pip installed invoke into it. And, assuming that you have defined a task in your tasks.py file as follows:→ Continue reading “Creating a Launch Config in VSCode to Debug a Python Invoke Script”
