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 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!

Sudo for Windows
This smells like when PowerShell aliased curl and wget to a completely different command, with incompatible arguments.

Gooey: Turn almost any Python command line program into a full GUI application
PowerShell is available on macOS and Linux as well (source on Github: https://github.com/PowerShell/PowerShell). It may not be as well-integrated with things like system services management, but the language still works well. You can still use all the command line tools you're used to on Linux, of course.
nushell does look interesting, though the lack of a .deb repository does put it pretty low on my to-do list.

Just messing around with arrays and efficiency in PS, thought I'd share
Note: This can be problematic as it prevents upstream commands from running their end {} block. See here. The new clean {} block introduced in PowerShell v7.3 does not suffer from this issue.

Jaq – A jq clone focused on correctness, speed, and simplicity
Can you give an example of something that PS can do that is built-in for text processing, instead of a proprietary symbolic query language?

The bash book to rule them all
https://github.com/PowerShell/PowerShell/blob/master/LICENSE... is the MIT license. (Microsoft supplies debs directly which may reduce the motivation for Debian to do so.)
Oh, heh, also https://github.com/PowerShell/PowerShell/blob/master/docs/bu... the build script is written in PowerShell, so there's a bootstrapping problem :-) (Debian has solved those before of course, but with community sentiment like the above maybe noone is motivated to bother.)

Register-ArgumentCompleter: how to fall back to file completion when completing a flag such as "--foo="
According to https://github.com/PowerShell/PowerShell/issues/19628, the default behaviour is invoked whenever the completion script returns no output. To attempt to do so, I tried exiting the script via returning an empty string, or using the return keyword to exit the script completely, unfortunately with no avail. Is there a technique to achieve what I want, and is there any documentation about it other than the official one? Thank you in advance.
