I have found an interesting video about the xz backdoor, which got discovered on Easter 2024: https://youtu.be/aoag03mSuXQ The video starts with a jammed printer, but it is not my fault ... I had also

The video, with its thumbnail telling that it is all about the XZ problem, started right away with that it all started with a jamming printer, so not knowing in these first seconds that they also explain the origin of FOSS, my first thought got "Was it me?" ... but seconds later I saw that it was about Richard Stallman.
Both Richard and me, our work was triggered by printers, Richard created the concept of FOSS and I created OpenPrinting ...

@Daojoan@mastodon.social I am posting news about my work at #OpenPrinting regularly and did already for more than 5 years.
I intentionally do this as a written blog and not as videos, as on the blog you can search text, easily navigate, you can copy example code and paste, auto translators work better on written than on spoken text, same for accessibility tools ...
Or do you prefer watching an old graybeard talking, and for those who want video, I get interviewed here and then.

... mirrored carbon copy on the front side of the "matrice".
This "matrice" you put into the alcohol duplicator to make the actual copies onto special sheets for alcohol duplication.
Note that to create the carbon copy on the "matrice" you NEED an impact printer (dot matrix "pin" printer, daisy wheel printer, line printer, typewriter, hand drawing/writing with pressure), as non-impact printers (inkjet, laser) will not produce the carbon copy.
