There are two keywords that are killers: "news" and "world" and their translations or closely related words. Everything else is hard. So a good start is:

grep -e news -e noticias -e nouvelles -e world -e global

iran + football:

3 easy hits with "noticias" (news in Portuguese or Spanish"), uncovering two brand new ip ranges:

Let's see some French "nouvelles/actualites" for those tumultuous Maghrebis:

news + world:

news + global:

OK, I've decided to do a complete Wayback Machine CDX scanning of news... Searching for .JAR or https.*cgi-bin.*\.cgi are killers, particularly the .jar hits, here's what came out:

Wayback Machine CDX scanning of "world":

"headline": only 140 matches in 2013-dns-census-a-novirt.csv and 3 hits out of 269 hits. Full inspection without CDX led to no new hits.

"today": only 3.5k matches in 2013-dns-census-a-novirt.csv and 12 hits out of 269 hits, TODO how many on those on 2013-dns-census-a-novirt? No new hits.

"world", "global", "international", and spanish/portuguese/French versions like "mondo", "mundo", "mondi": 15k matches in 2013-dns-census-a-novirt.csv. No new hits.

Edit: Carson was found Oleg Shakirov's findingsby Oleg Shakirov: alljohnny.com, communicated at: twitter.com/shakirov2036/status/1746729471778988499, earliest archive from 2004 (!): web.archive.org/web/20040113025122/http://alljohnny.com/, The domain was hidden in plain sight, it was present in a not very visible watermark visible in the Reuters article screenshot! The watermark was added to the CIA to the background image, it is actually present on the website. In retrospect, it was actually present at on the expired domain trackers dataset, but the mega discrete all second word made Ciro Santilli miss it: github.com/cirosantilli/expired-domain-names-by-day-2015/blob/9d504f3b85364a64f7db93311e70011344cff788/07/05/02#L1572

What follows is the previous

The fact that the Reuters article has a screenshot of it, and therefore a Wayback Machine link, plus the specificity of the website topic, will likely keep Ciro awake at night for a while until someone finds that domain.

Some text visible on the Reuters screenshot:It is unclear however if this text is plaintext or part of a an image.

Some failed attempts, either dry guesses or from DNS grepping dataset searches:

Searching the Wayback Machine proved fruitless. There is no full text search: Wayback Machine full text search, and a heuristic web.archive.org/web/20230000000000*/Johnny%20Carson search has relevant hits but not the one we want.

Another attempt was to search for "carson" on webmasterhome.cn which lists expired domains in bulk by expiration day, and it search engine friendly. It contains most of the domains we've found so far. Google either doesn't support partial word search or requires you to be a God to find itso we settle for DuckDuckGo which supports it: duckduckgo.com/?q=site%3Awebmasterhome.cn+%22carson%22&t=h_&ia=web Adding years also helps: duckduckgo.com/?q=site%3Awebmasterhome.cn+%22carson%22+2011&ia=web with this we might be getting all possible results. Ciro went through all in 2011, 2012 and 2013 but no luck. Also fuck en.wikipedia.org/wiki/Carson_City,_Nevada and en.wikipedia.org/wiki/Carson,_California :-)

Let's search tools.whoisxmlapi.com/reverse-whois-search for "carson" contained in any historic domain name. 10,001 lines. Grepping those, no good Wayback machine hits for those that also contain "johnny" or "show". Data at: raw.githubusercontent.com/cirosantilli/media/master/cia-2010-covert-communication-websites/tools.whoisxmlapi.com_reverse-whois-search_carson.csv in case anyone want to try and dig...

Let's also search the fortuitously timed 2013 DNS Census.

If there is one thing that makes Ciro Santilli learn German, this is it (the Romance language are all the same, so reading them is basically covered for Ciro already).

Much of this section will be dumped at Section "Website front-end for a mathematical formal proof system" instead.

A more verbose description of this at: Section "Website front-end for a mathematical formal proof system".

Their status is a mess as of 2020s, with several systems ongoing. Long live the "original" collegiate university!

The Taylor series expansion is the most direct definition of the expontial as it obviously satisfies the exponential function differential equation:

The orthogonal group has 2 connected components:

It is instructive to visualize how the $\pm 1$ looks like in $SO(3)$:

As a result it is isomorphic to the direct product of the special orthogonal group by the cyclic group of order 2:

A low dimensional example:because you can only do two things: to flip or not to flip the line around zero.

Note that having the determinant plus or minus 1 is not a definition: there are non-orthogonal groups with determinant plus or minus 1. This is just a property. E.g.:has determinant 1, but:so $M$ is not orthogonal.

Some specific examples:

symmetric bilinear maps that is also a bilinear form.

The complex number analogue of a symmetric bilinear form.

The prototypical example of it is the complex dot product.

Note that this form is neither strictly symmetric, it satisfies:where the over bar indicates the complex conjugate, nor is it linear for complex scalar multiplication on the second argument.
