PDFZilla overrides PDF's copy protection

Giveaway Of The Day recently offered a FREE licensed copy of PDFZilla. PDFZilla has a option to convert a PDF to Word, RTF or text file format.

I was a little surprised to discover that it can even convert PDFs with copy protection and as a result text can be copied from the converted file. I (naively?) believed that the a PDFs copy protection property was unbreakable. In fact there seem to be other tools as well that can bypass a PDF's copy protection.

I wanted to share this finding so that others wanting to protect their PDFs are not under the mistaken belief that the protection mechanism is reliable.

GitHub Copilot Q&A - 1

Key takeaways from the talk in Q&A format - What is GitHub Copilot and how does it work? GitHub Copilot is a suite of tools designed for code completion. It works by analysing the code and comments you type in your IDE and sending that context to GitHub. Copilot then uses OpenAI's language model (in December 2024, it is GPT 4o by default and you can also choose the preview versions of o1-mini & o1-preview if you like) to understand your intent and generate suggestions for code completion. You can then accept, reject, or modify these suggestions. What context does GitHub Copilot consider when making suggestions? Copilot considers the entirety of the file you are currently working on, not just the code from your cursor position upwards. It also analyses the content of other open tabs in your IDE, starting with those closest to the current tab. This helps Copilot focus on the most relevant information. Is it necessary to meticulously manage open tabs for Copilot to work effect...
