Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

From slow to SIMD: A Go optimization story
I did a similar optimization via https://github.com/viterin/vek as the SIMD version. Some somewhat unscientific calculations showed a 10x improvement staying in float32: https://github.com/stillmatic/gollum/blob/07a9aa35d2517af8cf...
TBH my takeaway was that it was more useful to use smaller vectors as a representation

Agency: Pure Go LangChain Alternative
I like Go a lot for working with OpenAI etc, it's 'just' API calls and Go is great at that. I've opensourced some bits here: https://github.com/stillmatic/gollum -- in particular, function dispatch (given a prompt, return an arbitrary Go struct) is really nice, as is a very fast in-memory KNN index.

FANN: Vector Search in 200 Lines of Rust
I have gotten 10x speedups with SIMD on modern hardware. Goroutines make this actually fairly tricky, as you essentially have to process all the events and then sort the entire array, which is usually the bottleneck. The heap adds a small amount of complexity but is significantly more efficient, feels like good ROI.

Looking for help with transpiling TypeScript to Golang and Python using LLMs
For a auth product, you probably should go with traditional code generation, not LLMs (re: all the unsolvable problems they have (hallucinations, incomplete code answers). For an auth product, you want something definite and reproducible, or you are asking for trouble.
If you are interested in a flexible code gen framework, I built one that had this very use case in mind. (https://github.com/hofstadter-io/hof)
I'd be happy to think / talk this through with you

Ask HN: Interesting TUIs (text user interfaces), maybe forgotten ones?
I recently built a TUI for exploring and developing CUE, JSON, Yaml.
Large inspiration for the overall UX comes from the Bloomberg terminal, where every function is reachable with four letter shortcut from the command box. It was really the command box that I liked. I've also built a sort of "flex" panel component for the layout so you can create as many panels as you like.

Ask HN: Are SQL developers generally familiar with JSON, VSCode and Docker?
Many business analysts use SQL, have for a long time. They are probably not your target audience. With the problem being JAVA specific, you'd likely want to start there
This sounds similar to the goals of my hof tool (https://github.com/hofstadter-io/hof), lift type definitions out of code so they can be defined in one place, then generate the code for all the places. Is that sounding like what you are after?

Show HN: Open SaaS – An open-source alternative to paid boilerplate starters
Having built something similar, the biggest challenge for users is that they have to use a bespoke language, like WASP here. I suspect that it is also your biggest challenge as well.
Mine is built on CUE, which at least has the potential to become a more widely used language. CUE hasn't reached sufficient maturity for broader adoption yet, so I continue to face this same problem.

OpenAI: Prompt Engineering
Here's a big one I needed to get ChatGPT to do something more sophisticated with a JSON object response (predates functions and all that)
https://github.com/hofstadter-io/hof/blob/_dev/flow/chat/pro...
It no longer worked after a model update some time ago, haven't tried recently.
I found codellama to be much better for this and require fewer instructions, an anecdotal validation for smaller, focussed models

Ask HN: What's the most compelling AI prompt result you've seen?
I was surprised out how you can define arbitrary grammars using arbitrary formulation and it would follow it. Of course you have to redo the prompt every time there is an update... such a pain

HTTPie Desktop: cross-platform API testing client for humans
CUE is indeed a beautiful language, will get those mind juices flowing for sure!
There is more work to be done on the codec implementation, but if you just want to split yaml/json across files, CUE is a great option
You might also like my project, built on CUE: https://github.com/hofstadter-io/hof We have a TUI where you can explore and work with CUE, JSON, Yaml

Show HN: A tool to Convert JSON schemas into TypeScript classes
You can pretty much make up any pseudo grammar like this one, which is a reduced JSON object that is close to CUE: https://github.com/hofstadter-io/hof/blob/_dev/flow/chat/pro...
No need to be formal or use a standard format

Guidance: A guidance language for controlling large language models
Yea, in particular for this project, they have created a bespoke templating system.
You can get the same thing with Go text/templates by adding chat function(s) as custom a helper: https://github.com/hofstadter-io/hof/blob/_dev/lib/templates...

Textual Web: TUIs for the Web
100% one of the best things about building a TUI is not having the pain of modern web development. I do think there is a way to have a CLI & TUI come from the same code, so you can get the best of both, or pick the best for the task at hand.
