ChatGPT Resources

Context

ChatGPT appeared like an explosion on all my social media timelines in early December 2022. While I keep up with machine learning as an industry, I wasn't focused so much on this particular corner, and all the screenshots seemed like they came out of nowhere. What was this model? How did the chat prompting work? What was the context of OpenAI doing this work and collecting my prompts for training data?

I decided to do a quick investigation. Here's all the information I've found so far. I'm aggregating and synthesizing it as I go, so it's currently changing pretty frequently.

Model Architecture

Upgrade systemd on Ubuntu 18.04

In this document, I will explain how to upgrade the default systemd version from 237 to 242.

The main reason why I needed this was related to the DNS-over-TLS that was not supported in the version 237 but available from version 242.

Later, when playing with Lynis, the security auditing tool, I then discovered that the version 242 was also providing the command systemd-analyze that is used by lynis to detect if existing systemd services are configured correctly in the security context, meaning that the existing services can run as expected but needs few or several changes in their configuration to make them safe without any exploitable attack surfaces.

You can try it once you've installed the version 242 of systemd that way:

How to create Apple PKPass .p12 certificate using Linux

You don't need a Mac to do this :-)

For generating PKPass files, you'll need 4 things after this tutorial:

Certificate Identifier (pass.com.example.www)
Team Identified (Organizational Unit (OU) in the cert generated by Apple)
The .p12 file
The password for the .p12 file
