Talk:Discrete Fourier transform

I have been waffling back and forth on whether the 1/N term belongs in the fourier transform or in the inverse fourier transform.

Recently, I have been focusing on the issue of adding non-fourier terms to a fourier series. (Should this be accomplished by adding to the first term, or by adding to all terms? Each approach favors the opposite placement for that 1/N term.)

It doesn't help that currently, we're having problems displaying updates involving LaTeX... --Rdm (talk) 02:09, 28 April 2021 (UTC)


Failed to parse (http://mathoid.testme.wmflabs.org server response is invalid JSON.)

Currently, this page is littered with error messages of the form "Failed to parse (http://mathoid.testme.wmflabs.org server response is invalid JSON.)".

I believe what's happening is that server redirects from http to https and we get a certificate error on the https response, because the certificate is for wmflabs.org and not mathoid.testme.wmflabs.org

Possibly relevant here is https://wikitech.wikimedia.org/wiki/Help:Using_a_web_proxy_to_reach_Cloud_VPS_servers_from_the_internet which is about administering wmflabs.org proxy servers (which I think the mathoid server is an example of), and which explains that this is an old domain and needs to be updated.

I don't know enough to recommend a solution here, but this smells like something someone set up a long time ago, then moved on, and someone else needs to rebuild that part of the wikimedia system. --Rdm (talk) 19:41, 12 June 2021 (UTC)

Oh, good.   I thought it was just my old and outdated FireFox software that was being bitched about   (or because of).   Glad somebody else took the time to express was is going wrong.
