 # Random Weird Things - Part Ⅳ

 Every so often I stumble upon random, weird, and completely unexpected things on the internet. I thought it would be neat to share them here from time to time. This is the fourth run.

 ## 36. LLM Rescuer 🤖💰
 
-LLM Rescuer is a tiny Ruby wrapper that retries, sanitizes outputs, handles errors, and has some token-saving logic so you don't burn through your budget. It interprets nil references automatically based on the context. Examples:
+LLM Rescuer is a tiny Ruby gem that hooks into Ruby's method dispatch so that calling a method on `nil` doesn't crash — it asks an LLM what the return value should be instead. When a `NoMethodError` would normally explode, the gem catches it, packages up the context (what method was called, what the variable name suggests, maybe the surrounding code), fires that off to an actual LLM API, and returns whatever the model hallucinates as sensible.
+
+So `user.email` on a nil `user` doesn't die. It asks the LLM "someone called `.email` on a `user` that turned out to be nil, what should I return?" and the model says "probably `'no-reply@example.com'`". The gem swallows the error and hands you that string.
+
+It tries to keep API costs down by sending only minimal context — just the method name and variable name rather than your whole codebase — but every nil-hit still costs tokens and adds latency.
+
+This is runtime monkey-patching powered by a remote AI. Your nil bugs don't crash, they silently return AI-guessed values. In production this would be a debugging nightmare.

 ## 37. Filesystem Backed by an LLM
 
-Mount a folder, and every time you read or write a file, an LLM decides what the contents should be. Want a config file? Ask the LLM. Need a todo list that rewrites itself when you look at it? There you go. There's a working FUSE implementation. Equal parts brilliant and terrifying.
+Mount a folder via FUSE, and every time you read or write a file, an LLM decides what the contents should be. There's a real working implementation. You literally `cat` a file and the LLM generates the output on the fly.
+
+Example usage:
+
+```sh
+$ echo "a nginx config for a reverse proxy to localhost:8080" > /mnt/llmfs/nginx.conf
+$ cat /mnt/llmfs/nginx.conf
+server {
+    listen 80;
+    location / {
+        proxy_pass http://localhost:8080;
+    }
+}
+
+$ echo "my todo list for today" > /mnt/llmfs/todo.txt
+$ cat /mnt/llmfs/todo.txt
+- Write blog post
+- Fix that bug in prod
+- Drink coffee
+
+$ cat /mnt/llmfs/todo.txt
+- Write blog post (done?)
+- Fix that bug in prod
+- Drink more coffee
+```
+
+The LLM hallucinates the file contents every single read. Your todo list literally mutates when you look at it. Want a config file? Just describe it in the filename or write a prompt into it. Equal parts brilliant and terrifying.
