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.

How to fit a polynomial P of degree D to a vector of roots?
Here's how to do it with Grassmann.jl

Grassmann.jl now has SimplexComplex{V,B,T} wrapper for Complex{T}
Surprise announcement: the next version of Grassmann.jl has a new algebra type SimplexComplex{V,B,T} (yes, that's right SimplexComplex) which is a wrapper for Julia's native Base.Complex{T} type. This allows you to work with the performance of the base language complex numbers while retaining the Grassmann algebra interface and additional products. The new type is not limited to only regular complex numbers, it supports the creation of a SimplexComplex using any basis element B by simply taking the sum of a scalar with that basis element. ```Julia julia> using Grassmann

Einstein award going to Paul Ginsberg for creating arXiv.org
I still have never been able to post my paper about my Grassmann.jl geometric algebra foundations research on arxiv.
https://github.com/chakravala/Grassmann.jl
Seems like a useless overrated website.
I was able to post my article on my own website instead.
Arxiv is really a useless website.

What Is the Inverse of a Vector?
This article is really about geometric algebra, check out my geometric algebra software https://github.com/chakravala/Grassmann.jl
- Stop what you're doing and look up Geometric Algebra on yt right now
- Ask HN: What are some tools / libraries you built yourself?

Ask HN: What under-the-radar technology are you super excited about?
https://github.com/chakravala/Grassmann.jl
In the future, geometric algebra will likely be part of everything we do, but it is still very unknown as of now.

My advanced math skills are going down the drain
I heart your Grassman gradient vector field representations: https://github.com/chakravala/Grassmann.jl. They, heh heh, point the way toward representing aspects of physics and math that should be used far more frequently than they are now. They display the quirks that you could never apprehend looking at an equation. Your representations could eviscerate the representations of data base on paper-like metaphors.
Sadly our leaders, the John Baez and Scott Aronson and people like that, prefer to think in Euler notation and WordPress posts. As Kurt Vonnegut said: So it goes.
The world of representation of difficult concepts using interactive 3D and elegant code is still in its infancy. You are not yet at the ground floor of the construction of a future elegant structure. You - and a few others - are in at the second basement.
Fortunately, the only way out is to look up!

Pkl, a Programming Language for Configuration
I'm really enjoying reading through the docs and the tutorial. We've created Lowdefy, a config web-stack which makes it really simple to build quite advanced web apps. We're writing everything in YAML, but it has it's limitations, specifically when doing config type checking and IDE extensions that go beyond just YAML.
I've been looking for a way to have typed objects in the config to do config suggestions and type checking.. PKL looks like it can do this for us. And with the JSON output we might even be able to get there with minimal effort.
Is there anyone here with some PKL experience that would be willing to answer some technical questions re the use of PKL for more advanced, nested config?

Show HN: Retool AI
Awsome! With Lowdefy we tried to build a low-code framework that works like code. We’ve developed a schema in which to define applications and we’ve built all kinds of apps for enterprise customers. Massive, advanced CRM systems, call centre solutions, ticketing systems, a light MRP, all kinds of survey apps and so many dashboards. Even our docs and our website are Lowdefy apps!
Give Lowdefy a try and reach out it you have any questions or want to see what is possible :) (We need to invest a lot more into content and examples, bootstapping is a grind!)

The Surprising Power of Documentation
100% this. And yes, good documentation takes a lot of investment but it pays off like compound interest. But with that done, it becomes even more important not to pull the carpet for no good reason, you are building a tower and documentation is at the foundation.
We’ve built Lowdefy [1] as an open source project and documented it with all effort, 200 pages of docs. I often forget why or how something works and then jump to the docs. This investment keeps on paying of as we use Lowdefy to build customer apps, new devs in the team typically take less than two week to get up to speed and start making contributions, the sharp ones, just a two or three days.
This year, we’re extended our documentation onto customer apps aswell, with flow diagrams, state machine definitions, detailed field level explication schema definitions, and end user test procedures. The key here for this documentation is detail. It should be easier to reach for the docs and the the answer, than to dive in the code and interpret it.

AG Grid Community Roundup July 2022
Lowdefy is a low code tool that uses AG Grid as a block component, allowing you to create apps which render data in AG Grid without a lot of coding knowledge. There is a Lowdefy example using AG Grid here.

Show HN: ToolJet 1.2 OSS Retool alternative with realtime multiplayer editing
I’m also going to jump in here and say try Lowdefy https://github.com/lowdefy/lowdefy - co-founder here.
We take a different angle and believe that low code should still work like code. We focus on a developer first approach.
