Grassmann.jl VS Nullboard

Here's how to do it with Grassmann.jl

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

I still have never been able to post my paper about my Grassmann.jl geometric algebra foundations research on arxiv.

Seems like a useless overrated website.

I was able to post my article on my own website instead.

Arxiv is really a useless website.

This article is really about geometric algebra, check out my geometric algebra software 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.

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!

Hello, HN! I'd like to introduce you to nbagent[0], an open-source alternative backup agent for Nullboard[1] for Unix systems. If you, like me, are a fan of Nullboard's simplicity and you've been looking for an easy way to have your data backed up, check it out.

I'd love to hear your feedback on nbagent. Please feel free to leave comments, suggestions, or questions below.

Surprisingly no one has mentioned nullboard (https://nullboard.io/preview) yet. Just a single file JSON to carry around the entire board.

Nullboard maybe?

minimalist kanban board, without fancy tagging/time tracking/... features. Every game has a column, and notes are player names. nullboard would be perfect if it wasn't local only;

Nullboard - cool simple project, no bug tracking

Nullboard - Kanban board with dark mode, localStorage, and thoughtful UI

I use and like https://nullboard.io/preview nullboard which runs in the browser. Because it uses local data, you need to save it or the data is lost when you close the browser window.
