Electronic money Updated +Created
Our minimal definition of "electronic money" is the following.
Instead of creating legal tender such as Dollars as banknotes or transactions in some complex obscure banking system, the government offers an official simple centralized API that represents it instead.
Each citizen or legal entity has an account there, and transfers between registered users are just simple API calls.
So for example you would e able to put all your money in the government account instead of using useless banks. And then you would invest it as you want with the investment company of your choice, without tying the "my money is here" with "this is the best investment" aspects of banks.

Dynamic linking sections Updated +Created
This program did not have certain dynamic linking related sections because we linked it minimally with ld.
However, if you compile a C hello world with GCC 8.2:
gcc -o main.out main.c
some other interesting sections would appear.
Sections Updated +Created
Isomorphism Updated +Created
Something analogous to a group isomorphism, but that preserves whatever properties the given algebraic object has. E.g. for a field, we also have to preserve multiplication in addition to addition.
Other common examples include isomorphisms of vector spaces and field. But since both of those two are much simpler than groups in classification, as they are both determined by number of elements/dimension alone, see:we tend to not talk about isomorphisms so much in those contexts.
University of São Paulo Updated +Created
Ciro Santilli studied there for a few years starting in 2007.
In retrospect, doing electrical engineering (and likey the other engineering degrees) felt like taking a trip to the 60s in the United States, due to both the subject matter, and how old the concrete buildings were!
This does not need to be a bad thing. It is in that era (and earlier) that much of the exciting foundations of the field were set, and there is great value in there is value in tutorials written by early pioneers of the field. Not that they were amazing at excting history lessons as they should be. But the course outline suggested that intent.
But that point of view must also be accompanied by the excitement of the great ongoing advances of technology (and impact they had in the past). And on that, they failed.
One day, one day, we will fix that.

So we see that cl_from encodes the parent categories:
  • parent categories of categories:
    • en.wikipedia.org/wiki/Category:Computer_data_storage, which has ID 711721, has parent categories: "Computer hardware by type", "Computer data", "Data storage", "Computer architecture". This matches exactly on the database. These are all encoded on the source code of the page:
      {{DEFAULTSORT:Storage}}
      [[Category:Computer hardware by type]]
      [[Category:Computer data|Storage]]
      [[Category:Data storage|Computer]]
      [[Category:Computer architecture]]
    • en.wikipedia.org/wiki/Category:Computer_storage_devices has parent categories: "Computer data storage", "Recording devices", "Computer peripherals". This matches exactly on the database.
  • parent categories of pages:
    • en.wikipedia.org/wiki/Computer_storage_devices whish is a redirect gets the magic category "Redirects_from_alternative_names", a humongous placeholder with many thousands of pages: en.wikipedia.org/wiki/Category:Redirects_from_alternative_names
    • en.wikipedia.org/wiki/Computer_data_storage shows only two categories onthe web UI: "Computer data storage" and "Computer architecture". Both of these are present on the database and at the end of the source code:
      {{DEFAULTSORT:Computer Data Storage}}
      [[Category:Computer data storage| ]]
      [[Category:Computer architecture]]
      The others appear to be more magic. Two of them we can guess from the templates:
      {{short description|Storage of digital data readable by computers}}
      {{Use dmy dates|date=June 2020}}
      are likely Use_dmy_dates_from_June_2020 and Articles_with_short_description but the rest is more magic and not necessarily present in-source.
So to find all articls and categories under a given category title, say en.wikipedia.org/wiki/Category:Mathematics we can run:
mariadb enwiki -e "select cl_from, cl_to, page_namespace, page_title from categorylinks inner join page on page_namespace in (0, 14) and cl_from = page_id and cl_to = 'Mathematics'"
