I'm a software engineer in Bozeman, Montana! I'm sinking my teeth into Elixir + genAI and looking for others who are like minded! My other interests include Magic the Gathering, Improvisation, Yoga, the Cosmere, POE, Godot, and Rock Climbing.

Running llm's through each row of a csv is so powerful! Great for aggregating semantic meaning from arbitrary text!
(also a great way to spend a lot of money if your not careful 😅)

De-dupping articles when searching articles is super super important, don't want to influence the llm more than intended.

I know why we named ReAct agents (reason/action), but I can't stop thinking how funny it is we clashed names with the most popular web framework 😅

I liked the quote "Each supervision tree is a mini immune system."
It encapsulates how responsible and capable each process is in Elixir. With strong isolation and fault taulerant patterns like GenServer and Supervision trees, you can program a living piece of code.

Enum.sort([~D[2019-12-31], ~D[2020-01-01]], {:desc, Date})

This was tricky because because I'm rendering my markdown using Earmark from a file at runtime, not cached atm. To find this file I had to use this beautiful line of code.

If you are excited about what you do, your probably doing the right thing.
Always give yourself the opportunity to take a breath, minute, day, etc. to have those conversations with yourself and those around you.
But also trust your gut.

I'm really blown away by elixir's Ecto library. It looks to do so much with amazing examples. I specifically like the detail around tenant isolation, migration + schema cheat sheets, and examples based in postgreSQL 🐘

Processing data with an llm is like the blobs in a lava lamp. The data is big, then suddenly small, and magically large again.
Llms are great at summarizing lots of text into a statement. That statement can then be used for searching adjacent and relavent documents.

Monitoring LLM usage is essential for sustainable AI. Track token counts by model to find efficiencies, spending by use case to validate ROI, request latency for UX impact, and error rates to improve performance.

I made an assistant REPL which retains state! This loop updates a simple context object which stores previous assistant and user turns! The program also respects important commands like 'quit' and 'inspect' to exit and look at previous turns.

OK surely I'm not the first one to point out how jank this Python tuple syntax is for creating a tuple with one element. Use case is creating an immutable data structure.
>>> t = 1,
>>> type(t)
>>> t = (1,)
>>> type(t)
>>> i = (1)
>>> type(i)
#Python
>>> t = 1,
>>> type(t)
>>> t = (1,)
>>> type(t)
>>> i = (1)

Anthropic's brand is super clean and attracted me almost instantly. It feels soft, smart, and approachable. I set up their a Console account, bought 5$ worth of tokens, and used their Python SDK this morning to send in a prompt. I actually got an output back which feels amazing!!! ✨

OK it's official, I'm an AI Engineer starting tomorrow! I'm eager to wrap up my backend work and dive into Python and prompting best practices. On top of my list is learning the basics around Retrieval-augmented generation (RAG), prompt chaining, model comparisons, and output coherence.

Restricted Python is a great way to keep your app configurable but safe. It's a subset of your programming language, without all the security risks like deleting files, reading passwords, and writing malicious code. It also allows you to restrict imports via a whitelist feature!
