By GitHub around Black Lives Matter, due to a possible ludicrous relationship with slavery of black people:For the love of God, the word "master" is much more general than black slavery. If you are going to ban it, you might as well ban the word "evil".

Several software projects followed the purge from their codebases, maybe GitHub followed someone else's lead, it's hard to say.

The words "whitelist" and "blacklist" were also targeted.

pastebin.com/CTXnhjeS dated mega early on Sep 30th, 2012 by CYBERTAZIEX.

This source was found by Oleg Shakirov.

Holy fuck the type of data source that we get in this area of work!

This pastebin contained a few new hits, in addition to some pre-existing ones. Most of the hits them seem to be linked to the IP 72.34.53.174, which presumably is a major part of the fingerprint found by CYBERTAZIEX, though unsurprisingly methodology is unclear. As documented, the domains appear to be linked to a "Condor hosting" provider, but it is hard to find any information about it online.

From the title, it would seem that someone hacked into Condor and defaced all of its sites, including unknowingly some CIA ones which is LOL.

Ciro Santilli checked every single non-subdomain domain in the list.

Other files under the same account: pastebin.com/u/cybertaziex did not seem of interest.

The author's real name appears to be Deni Suwandi: twitter.com/denz_999 from Indonesia, but all accounts appear to be inactive, otherwise we'd ping him to ask for more info about the list.

www.zone-h.com lists some of the domains. They also seem to have intended to have snapshots of the defaces but we can't see them which is sad:

A theorem that is not very important on its own, often an intermediate step to proving something that the author feels deserves the name "theorem".

A polynomial of degree 1, i.e. of form $ax+b$.

A form is a function from a vector space to elements of the underlying field of the vector space.

Examples:

When it distributes it inverts the order of the matrix multiplication:

Easily classified as the direct product of cyclic groups of prime order.

Directly modelled by group.

For continuous symmetries, see: Lie group.

Some sources say that this is just the part that says that the norm of a $L^2$ function is the same as the norm of its Fourier transform.

Others say that this theorem actually says that the Fourier transform is bijective.

The comment at math.stackexchange.com/questions/446870/bijectiveness-injectiveness-and-surjectiveness-of-fourier-transformation-define/1235725#1235725 may be of interest, it says that the bijection statement is an easy consequence from the norm one, thus the confusion.

TODO does it require it to be in $l^1$ as well? Wikipedia en.wikipedia.org/w/index.php?title=Plancherel_theorem&oldid=987110841 says yes, but courses.maths.ox.ac.uk/node/view_material/53981 does not mention it.

A member of a tangent space.

Good ultra quick visual non-mathematical introduction to the Riemann hypothesis and analytic continuation.
