I love your description of "the dive". I am happy to see I am not the only one experiencing these recurring devouring interests that bring me much much deeper than I would like to go until I am starting to fork a github repo at 2am wondering "what the hell am I doing?"

And that article is tangentially related to a recurring interest of mine (shared editable 3d universe in which you can code collaboratively). If you happened to have an article comparing the merit of several server architectures/algorithms for collaborative text edition, I think many things can be related. I am now reading about CRDT (What the hell am I doing?) and that's something I may use to edit a scene graph collaboratively!

Hey thanks for that. :) Diving is super fun but also exceptionally exhausting. But often it's impossible to 'load' a complex problem in your head if you don't dive in for hours. Would be nice if there was a less stressful way.

In terms of editable 3d universes (whoah!), have you considered chucking together Three.js's JSON scene description (https://github.com/mrdoob/three.js/wiki/JSON-Object-Scene-fo...) with https://github.com/automerge/automerge, a CRDT for JSON? What could possibly go wrong?!

ShareJS has a JSON editor example https://github.com/josephg/ShareJS/tree/master/examples/publ...

Thanks! But a big part of my obsession is to be able to modify a 3d universe from within.

I won't claim it is practical or a good idea in any way, just an obsessive thing I want to try.

Right I understood that. I was replying to the other guy who suggested putting the scene in a JSON Three.js thing. So the idea was that the thing I suggested was just a possibly easy way to get a collaborative JSON editor into your program.

Diving usually happens to me when I resume coffee consumption after going dry for a few days :-)

Right now I am staying in the python world, that I know well, and appreciate its introspection capabilities. I play with OpenGL and PyQt to display in 3d the code of objects loaded in memory. It was surprisingly easy to do. When I first tried, 15 years ago, that was more of a mess.

Now I mentioned CRDT but I was not thinking on raw text but using nodes of the scene graph as characters. I like the idea of insertions and deletions that keep invisible tombstones available.

You've probably heard of it already, but if not you should check out the game Cube/Sauerbraten. It's an open source quake-style fps game, with its level editor integrated right into the game itself, and you can edit levels collaboratively with other players at the same time.
