Be sure to read the comments – Sam Aaron makes some important corrective points… The below left as documentation of thinking-in-progress.
There is now an exciting resurgence of interest in live programming languages within certain parts of the software engineering and programming language theory community. In general the concerns of liveness from “programming experience design” and psychology of programming perspectives, and the decade-old view of live coding and live programming languages from arts research/practice perspective are identical, with some researchers working across all these contexts. However I think there is one clear difference which is emerging. This is the assumption of code being live in terms of transience — code which exists only to serve the purposes of a particular moment in time. This goes directly against an underlying assumption of software engineering in general, that we are building code, towards an ideal end-game, which will be re-used many times by other programmers and end-users.
I tried injecting a simple spot of satire into my previous post, by deleting the code at the end of all the video examples. I’m very curious about how people thought about that, although I don’t currently have the methods at my fingertips to find out. Introspections very welcome, though. Does it seem strange to write live code one moment, and delete it the next? Is there a sense of loss, or does it feel natural that the code fades with the short-term memory of its output?
For me transient code is important, it switches focus from end-products and authorship, to activity. Programming becomes a way to experience and interact the world right now, by using language which expands experience into the semiotic in strange ways, but stays grounded in live perception of music, video, and (in the case of algorave) bodily movement in social environments. It would be a fine thing to relate this beyond performance arts — creative manipulation of code during business meetings and in school classrooms is already commonplace, through live programming environments such as spreadsheets and Scratch. I think we do need to understand more about this kind of activity, and support its development into new areas of life. We’re constantly using (and being used by) software, why not open it up more, so we can modify it through use?
Sam Aaron recently shared a great talk he gave about his reflections on live programming to FP days, including on the ephemeral nature of code. It’s a great talk, excellently communicated, but from the video I got the occasional impression that was is dragging the crowd somewhere they might not want to go. I don’t doubt that programming code for the fleeting moment could enrich many people’s lives, perhaps it would worthwhile to also give consideration to “non-programmers” or end-user programmers (who I earlier glibly called real programmers) to change the world through live coding. [This is not meant to be advice to Sam, who no doubt has thought about this in depth, and actively engages all sorts of young people in programming through his work]
In any case, my wish isn’t to define two separate strands of research — as I say, they are interwoven, and I certainly enjoy engineering non-transient code as well. But, I think the focus on transience and the ephemeral nature of code naturally requires such perspectives as philosophy, phenomenology and a general approach grounded in culture and practice. To embrace wider notions of liveness and code then, we need to create an interdisciplinary field that works across any boundaries between the humanities and sciences.
