I'm a Data Scientist. For some time, I've been working on a library for feature engineering.
• GitHub: https://github.com/feature-express/feature-express
• Website: https://feature.express
It isn't yet complete, and I wouldn't consider it ready for production use or handling larger datasets. Here are some of its characteristics:
• Event-based workflows: Initially, everything is converted to an event format, ingested into an event store, and processed from there.
• In-memory: Both the event store and evaluation have been built from scratch.
• Written in Rust, but there's a Python package available.
• A DSL (Domain Specific Language) for defining aggregations, similar to SQL.
Why am I developing this? I've always found it challenging to build models based on time. These models can be surprisingly tricky, and there's a high risk of accidentally using future data, which can lead to data leakage. FeatureExpress is designed to nearly eliminate such mistakes. Moreover, I believe that representing data as events is an intuitive approach.

#192I'm working on a todo list that uses 'j' and 'k' to navigate, and a hot bar of tools to manipulate the list. It's a local-first so the data is in your browser. I'll have to sync to a server soon.

#193explicable.ai
The frontpage is done, demonstrating the product. ML pipeline is ready. It lacks the CRUD backend though.
-- please review the site before comparing to my goals below, to see if it matches --
It brings insights (with nice pixels) by clustering together wrt the reason an ML model "reasons about" predicting a column in the dataset.
UX is simple: upload a CSV/excel, select a goal column and you are set.
I haven't spent much time marketing it if at all, and have gotten little feedback; and none wanting to pay for it.
If you see some interest in it, I'd love to talk about it. Or even integrate it in another product, for a fee

#194I’m working on a personal monitor mixer - a device musicians use the tailor their own mixes whilst recording, reducing cognitive load on the recording engineer - that integrates natively into modern AoIP deployments. I don’t know much about electronics beyond Ohm’s Law so it’s a massive learning curve. But it’s the most fun I’ve had in a long time.
Low budget embedded systems are what I'm all about, and I've done lots of audio stuff(And plenty of wondering why audio is still so analog, even though to am extern there's good reasons), always happy to help with something like that!

#195Back before Apollo the client for Reddit announced that it was going to disappeared, i started working on a client with the same dark scheme and ui feel as Apollo but for HN.
I did this as a way to play around with iPod development and swift and i made it pretty far, more than expected, using the hn api powered by fire ase.
I eventually got into an issue with hn stories with too many comments. I need to rethink my approach on how to handle these cases, otherwise the app crashes when it tries to render 800 comments or so.
Overall it was a fun learning experience.

#197AIPL is an "Array-Inspired Pipeline Language", a tiny DSL in Python to make it easier to explore and experiment with AI pipelines.
https://github.com/saulpw/aipl
When you want to run some prompts through an LLM over a dataset, with some preprocessing and/or chaining prompts together, AIPL makes it much easier than writing a Python script.

#198* Shell script replacement language that will also be useful as a production language. * Build system that people will actually love. (I hope.) * Init system that is easier to use than systemd, while also building distributed systems. * All-in-one VCS, like Fossil, but it can track changes to binary files.
I think you should definitely get some feedback on the details and specifics of the language before going further if you want it to make it to real production use.
Will you have a GitHub equivalent? Git is dominant I think because it's the standard all the tools are built for, no matter how good a competing system is, I'd probably choose on ecosystem. What's the use case list for binary file tracking? That seems pretty interesting!

#199I'm still building a low code system with an easy to use component marketplace where you can edit components within the low code tool. Still a work in progress: https://github.com/yazz/yazz

#200Homer Draft is fantasy baseball light that Jomboy used to play with his co-hosts on his podcast. I adjusted the rules slightly so that I could play w my family and friends more asynchronously (we just make picks and don't have to draft in order)
The two week "season" and then break makes it really fun. It gives importance to games that otherwise would just be one of 162. My wife who isn't into baseball now knows all the sluggers, can rank stadiums in order of HRs, and checks weather on game days at ballparks w/o roofs.
Next feature I need to add is separate leagues so other groups can play w friends.
