We don't like to use Github anymore because of the politics there. Example: We had a project involving software filters that included this sentence in the description:
> Phase is related to time, but a pure time delay does not involve any phase shift. A pure time delay or "group delay" is constant with frequency. Phase shift varies with frequency and can advance or retard as the frequency changes.
We got a note from a woman who works at github who was apparently scanning open source projects for "offensive" words. Our project was flagged for the use of the word "retard".
We removed our project and never used github again.
