Nix Language
To broaden my knowledge of nix, I'm working through an Overview of the Nix Language.
Thought Eddies
Zero to Nix
I started working through the Zero to Nix guide. This is a light introduction that touch on a few of the command line tools that come with nix and how they can be used to build local and remote projects and enter developer environments. While many of the examples are high level concept you'd...
Using Marvin for Structured Data Extraction
I've been following the "AI engineering framework" marvin for several months now. In addition to openaifunctioncall, it's currently one of my favorite abstractions built on top of a language model. The docs are quite good, but as a quick demo, I've ported over a simplified version of an example...
Migrating to Modules in Hugo
Go introduced modules several years ago as part of a dependency management system. My Hugo site is still using git submodules to manage its theme. I attempted to migrate to Go's submodules but eventually ran into a snag when trying to deploy the site.
Threading Macros
The threading macro in Clojure provides a more readable way to compose functions together. It's a bit like a Bash pipeline. The following function takes a string, splits on a : and trims the whitespace from the result. The threading macro denoted by -> passes the threaded value as the first...
OpenAI Function Calling
This past week, OpenAI added function calling to their SDK. This addition is exciting because it now incorporates schema as a first-class citizen in making calls to OpenAI chat models. As the example code and naming suggest, you can define a list of functions and schema of the parameters required...
Cloudflare D1
I was interested to learn more about the developer experience of Cloudflare's D1 serverless SQL database offering. I started with this tutorial. Using wrangler you can scaffold a Worker and create a D1 database. The docs were straightforward up until the Write queries within your Worker...
Trying out Jsonformer
I tried out jsonformer to see how it would perform with some of structured data use cases I've been exploring.
Tradeoffs of Using a Cache at Scale
Imagine we have a query to an application that has become slow under load demands. We have several options to remedy this issue. If we settle on using a cache, consider the following failure domain when we design an architecture to determine whether using a cache actually is a good fit for the use...
Protobuf contracts with LLMs
I've written several posts on using JSON and Pydantic schemas to structure LLM responses. Recently, I've done some work using a similar approach with protobuf message schemas as the data contract. Here's an example to show what that looks like.
