🥁🥁 You can now use EdDSA in #pdf signatures! ...well, at least we have an #ISO spec for it now. Quick write-up (+DIY demo) here: mvalvekens.be/blog/2022/iso-…
While I use a MacBook when travelling, I've used a Linux box as my main dev machine for most of the past decade :). You're right that the "PDF on the Linux desktop" experience is lagging behind, though. TL;DR: I use arch btw

I just wrote normal Japanese and Visual Studio Code warned like "oh, it is confusing character and you may want to use slash instead." shut up.
