It is cool that it exists but in EU we use qualified electronic signatures eIDAS that has cryptographic identification verification and national governments provides ability to sign documents using that protocol.

Signing pieces of paper is still a thing but emulating it digitally looks a little strange to me.

I got hooked by Youtube videos from TechnoTim Christian Lempa and others. Videos include screen capture what they are doing so it bridges some things that may be missing from text guide because it may be ‘obvious’ if you are doing it all the time.

I keep to principal that I have two ‘sections’ in my lab ‘production’ and ‘testing’ Testing I am mucking about testing stuff it works and production has some stuff that I rely on.
