For those of you new here, hello! My name is Ethan! I am a Research Software Engineer that is looking to build better infrastructure for molecular software. In my free time, I like building obscure parsers and writing Rust or Zig. If you want to see some of what I have done, checkout ethanholz.com!

Closed my account and haven't looked back. I find that there are a lot of people that are doing really cool stuff here and the conversations are just monumentally better and more respectful.

I think that a lot of that has to do with the fact that smart home tech has been poor to begin with. Even with user interaction, smart homes are still clunky. Projects like Home Assistant help here, but they still fail to deliver a good user experience. Smart home tech is flawed, and AI won’t help.

Pretty much! I was playing around with it when I was considering building a server rendered version of my blog, using the DID removed some complexity

Ethan Holz @ethanholz.com · 10d

Glad to hear it helped! Admittedly, I have been looking to use dids instead of handles for my own site!

Fighting the urge to build an open source inkjet printer again

I find my LLM usage is way down from what it was a few months ago. When I started to spend more time debugging code from an LLM rather than debugging my own code, I realized I wasn't actually building as much as it seemed. More importantly I wasn't building maintainable code.

Time for me to officially announce a passion project I have been working on for the last couple of months, directory.omsf.io! It is a directory of computational chemistry tools and workflows that is easy on the eyes! Read more about it here: blog.omsf.io/introducing-...!

are you a neovim user who knows how to best set up OCaml editor support in neovim?

We have editor Setup instructions for VSCode, Emacs, and Vim. However we keep encountering Neovim users who tell us how it was not obvious how to set up OCaml support (too many choices?). It would ...

This is for my UXG Max, which to get a bit hot in the rack so I wanted something that could handle the heat a bit better so PLA was out (at least with what I currently have). As for ASA, I don't have a good enough way to ventilate the space to print ASA yet, so I need something a little easier.
