How to paste signatures into PDFs using Okular Document Viewer
Okular is a very versatile document viewer found on many Linux distros but one of its shortcomings is not being able to just paste a transparent PNG format signature in. Pasting signatures into a PDF is often the commonly used method as most businesses want a plain 'signed' PDF that they can print and view. Although digital signing is more secure and legally accepted, most businesses are not geared to understand how to use these (much like with encrypted e-mails).
The workaround I show in this video, using custom stamps, is actually better than other document viewers in that you do not need to attach the file every time you want to paste a signature. You set up the custom stamp one, and just re-use that every time.

This sort of view gives a far more realistic feel for what the actual changes will look like.

Matrix is an open source project that publishes the Matrix open standard for secure, decentralised, real-time communication. You can self-host and federate, or join existing servers, to enable instant messaging, text chat in chatrooms, voice and video chat, file transfer, and even bridging between many other networks such as IRC, XMPP, Signal, Telegram, WhatsApp, RSS, Facebook Messenger, Discord, Slack, and many more.
End-to-End-Encryption, device verification and trust, replication of chatrooms for redundancy, are all hallmarks of Matrix. It can serve as a secure communications platform for governments with roving diplomats, or for end users be an alternative to Signal, Telegram and WhatsApp.
It is the opposite of a walled garden, with its vision of acting as a generic HTTP messaging and data synchronisation system for the whole web - allowing people, services and devices to easily communicate with each other, empowering users to own and control their data, and select the services and vendors they want to use.
