Setting up LangChain


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:

Not Lone LA Tuesday


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

Sunday from MoHo to Culver


I’m headed down to Culver City in a few hours, working from LA this week. Looking forward to it, even with the rain.

CO is playing with Meta’s VR screen pass-through using Immersed: I’m hearing impressed ooo’s and aaa’s as she sits on the floor with her laptop en-Quested. And, the technology itself is super impressed, allowing your laptop to use the VR goggles as multiple screens. VR is a bit low-res, the inputs are touchy, and the Quest is bulky, but! considering this is basically v1 I’m quite impressed. I would like to replace my laptop with a light pair of glasses / goggles some day.
