It is said, that once upon a time, programmers used CSV and collaborated on SourceForge, and that everyone was happy.
These days, are however, long gone in the mists of time as of 2020, and beyond Ciro Santilli's programming birth.
Except for hardware developers of course. The are still happily using Perforce and Tcl, and shall never lose their innocence. Blessed be their souls. Amen.

They do have some really good ones.
It is interesting that in different episodes they often switch the dominant/passive roles, so it's not fixed as in Laurel and Hardy.

Every mammal except the weird monotremes, i.e. marsupials and the placentalia.
The name is completely random, "wild beast". Are platypuses not "wild beasts"? They have a freaking poison!!
X-ray crystallography Updated +Created
One of its main applications is to determine the 3D structure of proteins.
Sometimes you are not able to crystallize the proteins however, and the method cannot be used.
Crystallizing is not simple because:
  • you need a considerable amount of the protein
  • sometimes it only crystallizes if you add some extra small chemical that stabilizes it
Cryogenic electron microscopy can sometimes determine the structures of proteins that failed crystallization.
CIA 2010 covert communication websites / 2013 DNS census SOA records Updated +Created

CIA 2010 covert communication websites / 2013 DNS Census virtual host cleanup Updated +Created
We've noticed that often when there is a hit range:
  • there is only one IP for each domain
  • there is a range of about 20-30 of those
and that this does not seem to be that common. Let's see if that is a reasonable fingerprint or not.
Note that although this is the most common case, we have found multiple hits that viewdns.info maps to the same IP.
First we create a table u (unique) that only have domains which are the only domain for an IP, let's see by how much that lowers the 191 M total unique domains:
time sqlite3 u.sqlite 'create table t (d text, i text)'
time sqlite3 av.sqlite -cmd "attach 'u.sqlite' as u" "insert into u.t select min(d) as d, min(i) as i from t where d not like '%.%.%' group by i having count(distinct d) = 1"
The not like '%.%.%' removes subdomains from the counts so that CGI comms are still included, and distinct in count(distinct is because we have multiple entries at different timestamps for some of the hits.
Let's start with the 208 subset to see how it goes:
time sqlite3 av.sqlite -cmd "attach 'u.sqlite' as u" "insert into u.t select min(d) as d, min(i) as i from t where i glob '208.*' and d not like '%.%.%' and (d like '%.com' or d like '%.net') group by i having count(distinct d) = 1"
OK, after we fixed bugs with the above we are down to 4 million lines with unique domain/IP pairs and which contains all of the original hits! Almost certainly more are to be found!
This data is so valuable that we've decided to upload it to: archive.org/details/2013-dns-census-a-novirt.csv Format:
8,chrisjmcgregor.com
11,80end.com
28,fine5.net
38,bestarabictv.com
49,xy005.com
50,cmsasoccer.com
80,museemontpellier.net
100,newtiger.com
108,lps-promptservice.com

The numbers of the first column are the IPs as a 32-bit integer representation, which is more useful to search for ranges in.
To make a histogram with the distribution of the single hostname IPs:
#!/usr/bin/env bash
bin=$((2**24))
sqlite3 2013-dns-census-a-novirt.sqlite -cmd '.mode csv' >2013-dns-census-a-novirt-hist.csv <<EOF
select i, sum(cnt) from (
  select floor(i/${bin}) as i,
         count(*) as cnt
    from t
    group by 1
  union
  select *, 0 as cnt from generate_series(0, 255)
)
group by i
EOF
gnuplot \
  -e 'set terminal svg size 1200, 800' \
  -e 'set output "2013-dns-census-a-novirt-hist.svg"' \
  -e 'set datafile separator ","' \
  -e 'set tics scale 0' \
  -e 'unset key' \
  -e 'set xrange[0:255]' \
  -e 'set title "Counts of IPs with a single hostname"' \
  -e 'set xlabel "IPv4 first byte"' \
  -e 'set ylabel "count"' \
  -e 'plot "2013-dns-census-a-novirt-hist.csv" using 1:2:1 with labels' \
;
Which gives the following useless noise, there is basically no pattern:

AI alignment Updated +Created
As highlighted e.g. at Human Compatible by Stuart J. Russell (2019), this AI alignment intrinsically linked to the idea of utility in economy.
Semiconductor device fabrication Updated +Created
This is the lowest level of abstraction computer, at which the basic gates and power are described.
At this level, you are basically thinking about the 3D layered structure of a chip, and how to make machines that will allow you to create better, usually smaller, gates.
The ideal university Updated +Created
This is a version of free gifted education but more focused on university.
This is Ciro Santilli's ideal university system. It is a system that actually lives up to the name "Open University":

So far as of the early 2020's, the university that comes closest to some but not all of these principles is the University of the People. It's sad that it's such a crappy unknown thing, but it is what it is.
