Ask HN: Can you help me find a blog that has been linked here before?

It is a machine learning blog that has been posted here before, and possibly referenced in a comment as well.

There were a few posts of note:

* A post that broke down the training costs of a human vs a LLM in terms of the information density of experiences that humans have to have to match an LLM.

* a post about his deep learning rig, which was a massive 8 gpu behemoth in an open case.

Some other things I remember:

* he recently accepted a position at openAI working as a machine learning engineer on their audio team.

* he lives in Colorado.

If you can help find it, I would appreciate it immensely!
