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.

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!

Ask HN: What are some tools / libraries you built yourself?
tabula-java [0], a library for extracting tables from PDF files. It started as a monolithic webapp written in JRuby, and we later extracted the table detection and segmentation logic into a Java library.
