Project mention: Ladder: Self-Improving LLMs Through Recursive Problem Decomposition | news.ycombinator.com | 2025-03-07There is https://www.rwkv.com/ which is an LLM based on RNN's, thus having "infinite" context length, it comes with its own tradebacks though. (Notably that its impossible to actually store infinite information in the network, so it prunes based on which information it finds more important.)

wj-config
JavaScript configuration module for browser and server projects that works like .Net configuration where any number of data sources are merged and environment variables can contribute/overwrite values by following a naming convention.
Project mention: How to Use TypeScript to Accumulate Types: Typing ALL possible fetch() Results | dev.to | 2024-11-30I also created wj-config, a package that aims towards the complete elimination of the obsolete .env files and dotenv. This package also uses the TypeScript trick taught here, but it joins types with &, not |. If you want to try it out, install v3.0.0-beta.1. The typings are much more complex, though. Making dr-fetch after wj-config was a walk in the park.
