It’s most likely an error with the nozzle height. The PEI plate not heating up enough shouldn’t cause the adhesion in the photo above (and this is not a first layer problem, as the error is not at a uniform height). Additionally, a few lines are very faintly visible on the plate where they shouldn’t be, indicating nozzle height. Make sure that it is easy to move a piece of paper between the nozzle and the PEI plate when adjusting the height, feeling only a very small amount of pressure as you do so.

That data might be easily accessible, but that was a choice Root made. I think that it is a safe assumption that Root knew most vigilantes keep their identity secret and, assuming a German background, had read Section 202 of the StGB and other relevant laws and court rulings. As such, Root most likely did this despite knowing their identity is at risk. It is likely they did this publicly specifically to inspire others, though I haven’t looked at all the details and there might be a different reason.

Nothing in this comment constitutes legal advice.

ASCII was interpreted as UTF because the function that checked whether the given text was Unicode checked the difference between bytes at even and odd positions. Many of the common phrases used to trigger this were in the 4-3-3-5 format (by letters), e.g., Bush hid the facts However, there was never any reason that this format of character placement was necessary for the bug (though even length was necessary)

Orca works great on Debian 13 for me (I installed it as a Flatpak)

The DKTB is a personal app. It is therefore assumed, that the User will not share it with other people, and that only the User can access and control their personal DKTB. Ultimately, this means that all attestations in a DKTB are expected to pertain to and only be presented by the same User. This is enforced by requiring the user to authenticate using biometry or PIN-code when using the app and only allowing the DKTB application to be installed on one device per user. (from the PDF)

This is a false assumption: PIN codes can be bypassed by sharing them with others. Devices can be faked unless using hardware attestation, which prohibits any modifications to the device which may be undertaken by those interested in rooting or installing a custom OS.

Users can initially acquire a DKTB on their smartphone or tablet via Google Play or the Apple App store. (from the PDF)

This method requires the use of a vanilla, unmodified device, effectively prohibiting modifications to devices that one might wish to alter.
