Programming is NOT meditative even the old way. Yes you can get into a flow state but that's not really meditation. In fact you're really just disassociating in a way and is easy to end stuck in your head too much. In fact, without balance, long periods of coding can leave some people feeling mentally over-identified with abstract thinking and less connected to their body or immediate experience.
It is also worth saying that you don't need to sit still to meditate. You can do yoga or go for a walk. Walking meditation is very underrated IMHO.
I'm sorry but I just find this slightly ridiculous. Create a 'frictionless' environment as much as you want but it is never going to make you write. If you want to write then just write and overcome the internal resistance. It's NOT a tools problem.
This is how LiveJournal was back in the day. I have some really fond memories of people just honestly writing about their life. It seemed more pure and less performative. Then of course the whole Six Apart thing happened but I know many Russians for whom LJ still serves the same purpose.
