![]() can tell the right moment to “steal” the keyboard and switch roles.can tell the right moment to give up the keyboard and switch roles.able to participate as driver, in particular to explain code while writing it.able to participate as navigator, in particular to intervene appropriately.This variant can be used purely for pedagogic purposes, or by already experienced programmers as a playful variant. When used simultaneously with test-driven development, one variant called “ping-pong programming” encourages more frequent switching of roles: one programmer writes a failing unit test, then passes the keyboard to the other who writes the corresponding code, then goes on to a new test. 2015: James Coplien publishes Two Heads are Better Than One which provides an overview of the history of Pair Programming that traces its origins back to the mid 1980’s if not before.Īs suggested above one of the major issues preventing effective pairing is passivity.2003: an anonymous article on the C2 Wiki describes Ping-Pong Programming, a moderately popular variant which marries pairing with test-driven development.2002: “ Pair Programming Illuminated“, by Laurie Williams and Robert Kessler, is the first book devoted exclusively to the practice and discusses its theory, practice and the various studies up to that date. ![]() 2000: (or earlier) – the roles of Driver and Navigator are introduced to help explain pair programming the earliest known reference is a mailing list posting note however that the reality of these roles has been disputed, for instance Sallyann Bryant’s article “ Pair programming and the mysterious role of the navigator“.1998: in “Chrysler goes to Extremes”, the earliest article about Extreme Programming, pair programming is presented as one of the core practices of the C3 team it is later described formally as one of XP’s original “twelve practices”.1995: the pattern “Developing in Pairs” is given a brief description, in Alexandrian pattern form, in Jim Coplien’s chapter “A Generative Development-Process Pattern Language” from the first patterns book, “Pattern Languages of Program Design”.Posterior studies are more abundant and driven by the desire to “validate” pair programming after it had already gained popularity through Extreme Programming. is one early empirical study indicating benefits of pairing for programming tasks specifically. 1993: “The benefits of collaboration for student programmers” by Wilson et al.Plauger, one of the implementors of C: “At each terminal were two programmers! Of course, only one programmer was actually cutting code at each keyboard, but the others were peering over their shoulders.” Whitesmiths existed from 1978 to 1988. 1992: “Dynamic Duo” is the term coined by Larry Constantine, reporting on a visit to Whitesmiths Inc., a compiler vendor started by P.J.However, the following timeline of verifiable sources does suggest that pair programming, in its modern form, has been around since well before the Agile movement: The names of various celebrities have been invoked in an attempt to imbue pair programming with an aura of necessity if not sanctity anecdotes of John Von Neummann, Fred Brooks, Jerry Weinberg, Richard Gabriel or Edsger Dijkstra using the practice are fascinating but sometimes hard to substantiate. pair programming cannot be fruitfully forced upon people, especially if relationship issues, including the most mundane (such as personal hygiene), are getting in the way solve these first!.at least the driver, and possibly both programmers, are expected to keep up a running commentary pair programming is also “programming out loud” – if the driver is silent, the navigator should intervene.a simplistic but often raised objection is that pairing “doubles costs” that is a misconception based on equating programming with typing – however, one should be aware that this is the worst-case outcome of poorly applied pairing.both programmers must be actively engaging with the task throughout a paired session, otherwise no benefit can be expected.More simply “pairing” the phrases “paired programming” and “programming in pairs” are also used, less frequently. The programmer at the keyboard is usually called the “driver”, the other, also actively involved in the programming task but focusing more on overall direction is the “navigator” it is expected that the programmers swap roles every few minutes or so. * Defines all of the ANSI terminal escape codes that modify the color of text.Pair programming consists of two programmers sharing a single workstation (one screen, keyboard and mouse among the pair). Here is how it would be used: fprintf(stdout, "Recognized text: %s\n", text ?: RED_TEXT("No text recognized.")) I have the following header included in some of my projects so that I can add a little color to the terminal output.
