Nu (letter) Updated +Created
Why would physicists use a letter such that:
  • the upper case version looks exactly like an upper case N. At least that is the correct pronunciation/name/historical successor of .
  • the lower case version looks exactly like a lower case V
Why? Why?????????
Ordered pair Updated +Created
Sets are unordered, but we can use them to create ordered objects, which are of fundamental importance. Notably, they are used in the definition of functions.

Ciro's call hierarchy notation Updated +Created
This is a simple hierarchical plaintext notation Ciro Santilli created to explain programs to himself.
It is usuall created by doing searches in an IDE, and then manually selecting the information of interest.
It attempts to capture intuitive information not only of the call graph itself, including callbacks, but of when things get called or not, by the addition of some context code.
For example, consider the following pseudocode:
f1() {
}

f2(i) {
  if (i > 5) {
    f1()
  }
}

f3() {
  f1()
  f2_2()
}

f2_2() {
  for (i = 0; i < 10; i++) {

    f2(i)
  }
}

main() {
  f2_2()
  f3()
}
Supose that we are interested in determining what calls f1.
Then a reasonable call hierarchy for f1 would be:
f2(i)
  if (i > 5) {
    f1()

  f2_2()
    for (i = 0; i < 10; i++) {
      f2(i)

    main
    f3
f3()
  main()
Some general principles:
  • start with a regular call tree
  • to include context:
    • remove any blank lines from the snippet of interest
    • add it indented below the function
    • and then follow it up with a blank line
    • and then finally add any callers at the same indentation level
