I edit text with PyCharm and check it in with GitHub.

I almost like Markdown and almost like Restructured Text. What kills the deal for me is that every dual-mode editor is slow. (e.g. like driving nails with a hammer which has a 4 to 6 second delay between the strike and the recoil)

I have a hobby of printing cards on an inkjet printer and I've written a "book" that gives step my step instructions for the whole process from image selection to installation.

I have a bunch of other things like that too.

My cards have a front and back side and often there is a QR code on the back which points to either an existing web site (a Type 1 card) or to a site managed by my system (Type 2 card.)

It's the thin edge of a very long wedge: it's a new take on the idea of "content management" because the "digital twin" of a card could be a photo shell like this

or a blog post or a small web application. Alternately a digital object has a "physical twin" I can share with people outside social media.
