Terrell rotation by Ciro Santilli 35 Updated +Created
What you would see the moving rod look like on a photo of a length contraction experiment, as opposed as using two locally measured separate spacetime events to measure its length.
Great doubt by Ciro Santilli 35 Updated +Created
The type of feeling of confusion and distrut for your sense that some Koans attempt to instill.
Ciro Santilli's preferred version of it is physics and the illusion of life.

Universal Module Definition by Ciro Santilli 35 Updated +Created
Since JavaScript devs are incapable of defining an unified import standard, this design pattern emerged where you just check every magic global one by one. Here's a demo where a Js library works on both the browser and from Node.js:

There's a tiny little crosshair that you can drag around to set the center of rotation.
Definition of the indefinite orthogonal group by Ciro Santilli 35 Updated +Created
Given a matrix with metric signature containing positive and negative entries, the indefinite orthogonal group is the set of all matrices that preserve the associated bilinear form, i.e.:
Note that if , we just have the standard dot product, and that subcase corresponds to the following definition of the orthogonal group: Section "The orthogonal group is the group of all matrices that preserve the dot product".
As shown at all indefinite orthogonal groups of matrices of equal metric signature are isomorphic, due to the Sylvester's law of inertia, only the metric signature of matters. E.g., if we take two different matrices with the same metric signature such as:
and:
both produce isomorphic spaces. So it is customary to just always pick the matrix with only +1 and -1 as entries.

BitcoinStrings.com by Ciro Santilli 35 Updated +Created
bitcoinstrings.com has all strings -n20 strings, we can obtain the whole thing and clean it up a bit with:
wget -O all.html https://bitcoinstrings.com/all
cp all.html all-recode.html
recode html..ascii all-recode.html
awk '!seen[$0]++' all-recode.html > all-uniq.html
awk to skip the gazillion "mined by message" repeats.
A lot of in that website stuff appears to be cut up at the 20 mark. As shown in Force of Will, this is possibly because they didn't use -w in strings -n20, and the text after the newlines was less than 20 characters.
That website can be replicated by downloading the Bitcoin blockchain locally, then:
cd .bitcoin/blocks
for f in blk*.dat; do strings -n20 -w $f | awk '!seen[$0]++' > ${f%.dat}.txt; done
tail +n1 *.txt
Remove most of the binary crap:
head -n-1 *.txt | grep -e '[. ]' | grep -iv 'mined by' | less
