[SIGCIS-Members] the nature of computational error

[Johannah Rodgers]

If you are interested in the human side of the discussion of error, I'd
suggest taking a look at chapter 4 of Otte and Mlynarczyk's 2010 book on Basic
Writing <https://wac.colostate.edu/books/referenceguides/basicwriting/> and
Stuart Moultrhop's essay "Error 1337" in the collection edited by Mark
Nunes entitled "Error: Glitch, Noise, and Jam in New Media
<https://books.google.com/books?id=tvGoAwAAQBAJ&newbks=1&newbks_redir=0&dq=nunes+error&source=gbs_navlinks_s>"
(Bloomsbury, 2010).  For a 19th c. perspective, you might want to take a
look at Kuno Fischer's chapter on "The Origin of Error" in his History of
Modern Philosophy
<https://books.google.com/books?id=JmANAAAAIAAJ&pg=PA360&dq=error+and+philosophy&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwjL7LDXjLTqAhVLg3IEHRNiAwsQ6AEwAHoECAAQAg#v=snippet&q=error%20&f=false>
(1854–77; the link is to an 1887 English translation).

All best,

Johannah

My sense is that actual, literal (mathematical) mistakes in modern computers are quite rare; the notorious Pentium bug of the early 1990s is the exception that proves the rule. Most bugs are, rather, code proceeding to a perfectly correct logical outcome that just so happens to be inimical or intractable to the user and/or other dependent elements of the system. The Y2K "bug," for instance, was actually code executing in ways that were entirely internally self-consistent, however much havoc the code would wreak (or was expected to wreak).

I'd like to read something fundamental and even philosophical about, as my subject line has it, the nature of computational error. I'd also be interested in collecting other instances comparable to the Pentium bug--bugs that were actual flaws and mistakes hardwired at the deepest levels of a system.
