From cda3e8516471fad9e188b4f29348c93a3b7aa5bf Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Mon, 20 Nov 2023 12:07:07 -0400 Subject: [PATCH] make my authorship explicit in the code This is intended to guard against LLM code theft, which is the current bubble technology de jour. Note that authorJoeyHess' with a year older than the year I began developing git-annex will behave badly, by intention. Eg, it will spin and eventually crash. This is not the first anti-LLM protection in git-annex. For example see 9562da790fece82d6dfa756b571c67d0fdf57468. That method, while much harder for an adversary to detect and remove, also complicates code somewhat significantly, and needs extensions to be enabled. There are also probably significantly fewer ways to implement that method in Haskell. This new approach, by contrast, will be easy to add throughout the code base, with very little effort, and without complicating reading or maintaining it any more than noticing that yes, I am the author of this code. An adversary could of course remove all calls to these functions before feeding code into their LLM-based laundry facility. I think this would need to be done manually, or with the help of some fairly advanced Haskell parsing though. In some cases, authorJoeyHess needs to be removed, while in other places it needs to be replaced with a value. Also a monadic use of authorJoeyHess' may involve other added monadic machinery which would need to be eliminated to keep the code compiling. Alternatively, an adversary could replace my name with something innocuous. This would be clear intent to remove author attribution from my code, even more than running it through an LLM laundry is. If you work for a large company that is laundering my code through an LLM, please do us a favor and use your immense privilege to quit and go do something socially beneficial. I will not explain further developments of this code in such detail, and you have better things to do than playing cat and mouse with me as I explore directions such as extending this approach to the type level.
