Rhetorical Ontologies of Code Kevin Brock University of South Carolina [email protected] / @brockoleur http://www.brockoleur.com Object-Oriented Rhetoric • Barnett: is rhetoric a ‘human art’ ? (2010, n.p.) • Brown: ‘attitudinal worlds’ constructed by ‘all relations’ between humans & objects (2012, n.p.) Kevin Brock / University of South Carolina / [email protected] / @brockoleur Network / Software Theory • Galloway & Thacker: protocol as a way to understand ‘tendencies’ of network agents to operate via interrelations (2007, p. 28) • Protocol, as method of control & influence to facilitate particular relations, must be inherently rhetorical Kevin Brock / University of South Carolina / [email protected] / @brockoleur Ken Thompson’s C Compiler Hack • Thompson: code is inherently untrustworthy as one cannot, or will not, create all of his or her code (1984, p. 763) • Thompson supports this claim by hacking the C compiler (a program to turn source code into executable files) Kevin Brock / University of South Carolina / [email protected] / @brockoleur The C Compiler Hack ... c = next( ); if(c != '\\') return(c); c = next( ); if(c == '\\') return('\\'); if(c == 'n') return('\n'); if(c == 'v') return('\v'); ... ... c = next( ); if(c != '\\') return(c); c = next( ); if(c == '\\') return('\\'); if(c == 'n') return('\n'); if(c == 'v') return(11); ... compile(s) char *s; { if(match(s, "pattern1")) { compile("bug1"); return; } if(match(s, "pattern2")) { compile("bug2"); return; } ... } (Thompson, Figure 2.2) (Thompson, Figure 2.3) (Thompson, Figure 3.3) Kevin Brock / University of South Carolina / [email protected] / @brockoleur The C Compiler Hack Clean Code Clean Compiler Clean Executable (processing code normally before Thompson’s hack is implemented) Unclean Code Clean Compiler Infected Executable (inserting Thompson’s Trojan Horse) Clean Code Infected Compiler ‘Clean’ Executable (incorporating the infected compiler into the normal process) Clean Code ‘Clean’ Compiler ‘Clean’ Executable (replacing the infected compiler with a cleansource compiler) Kevin Brock / University of South Carolina / [email protected] / @brockoleur Who or What Has Agency Here? • Latour: technology is ‘an interchange between what humans inscribe in it and what it prescribes to them’ (1996, p. 213) • Being emerges from rhetorical activity for Trojan Horse author, code languages, physical computer, electrical flows/digitizations, etc. Kevin Brock / University of South Carolina / [email protected] / @brockoleur DNA (Codon) Reprogramming • Lajoie et al. reprogram three-nucleotide sequences (codons) to facilitate new types of chemical reactions between amino acids & proteins (2013) • Potential applications include new adhesives, medications, disease-resistant foods Codon Reprogramming Lajoie et al. (2013, Figure 1) Chemical Programming with DNA • Chen et al. construct a new programming language for consensus-based calculation using ‘complex signal processing’ from biological & chemical inputs (2013, p. 755) Kevin Brock / University of South Carolina / [email protected] / @brockoleur Chemical Programming X = majority species signal Y = minority species signal B = buffer signal Solid lines = consensus results Dashed lines = anticipated (computed) results Kevin Brock / University of South Carolina / [email protected] / @brockoleur Chen et al. (2013, from Figure 5) Agency in DNA Programming • Rhetorical agency and being exist in DNA nucleotides, protocols of combination, chemical reaction responses, generated proteins, human researchers, modified organic and inorganic entities Kevin Brock / University of South Carolina / [email protected] / @brockoleur Programmatic Persuasion • Code, biological and technological, serves to ‘program’ (rhetorically persuade) agents to act – Facilitating novel means of invention in response to emerging situations / contexts • How can we recognize this rhetorical activity as it takes place in numerous iterations daily?
