Happy April 2nd!

I’m busy this evening, heading North for home tomorrow, but at this moment early in the day it’s my own time. So! Using that time to get a massive sleep in, catch up on the hours I missed over the week. True rest day.

One note on guix: a full garbage collection (guix gc) cleared out nearly 200GB, however many of those packages were used for builds. So, updating my Guix Home profile after the GC resulted in an expensive build dependency resolution step.

LangChain provides a Pythonic framework for writing LLM powered applications, e.g. tools for asking questions re knowledge bases, personal assistants, chatbots, etc. Given it provides a toolkint to implement “smart” apps, I wanted to go through the motions of implementing something simple + useful.

I started wiring LangChain to my org files and emails but I wasn’t able to fully take it through it’s paces. While most of my organized thoughts are in the org files, there doesn’t seem to be an unstructured parser for it. This means all of the semantic structure (headings, tags, linnks, etc) is lost in raw text parsing & splitting. Solution-wise, should be easy enough to convert the org files to HTML which unstructured will devour happily. Email have their own problem, namely persisting the Chroma vectorstore index because it takes a while to index my tens of thousands of emails. Should also be easy enough with LangChain, but I’m still learning the API calls to pull it off.

Aiming for an HIIT exercise given the falling rain outside. Tomorrow’ll be a perfect day (read: not raining) for back & biceps.

LX intro’d me to two generative AI chaps, helping me feed my brain with this space. Specifically, I’d like to know:

• what are they working on? what are they excited about?
• is it just the best & biggest model (GPT-4), that works the best?
• similarly, is fine-tuning worth it?
• what is the most cost-effective path for self-hosting?

Getting a LangChain environment set up on Guix is teaching me some tricks. I was unable to install the Python hnswlib due to missing a C++ build dependency in my global / home profiles. I spun up a temporary environment with the build deps installed:

Got to see LX and RN today! Glorious fellas. Now, I am tired and go to bed.

A real reel to reel day. Well tired and headed to bed.

Yesterday’s chest workout was super feeble, maxing out way below the previous week’s. The cause seems to’ve been the few beers I led with – no free fun. Feeling back on my spinach today:
