Speaker Rider

Last updated 14 April 2021

What is a speaker rider?

As speaking comes with immense privilege, I have crafted a speaker rider to set expectations and boundaries around my engagement. I am grateful to all the conference organisers who have brilliantly hosted me. I would love to continue to exercise this privilege to speak at conferences, and use this privilege to make the landscape more accessible and beneficial to tech's most historically excluded and marginalised communities.

Considerations

😫 I provide a lot of explanations for those of you who never had to consider these things. Most thoughtful conferences I've attended check most of these boxes intrinsically, particularly when conference runners are experienced speakers. They get it.

	decompose <- function(expr) {
	expr <- substitute(expr)
	funs <- setdiff(all.names(expr), all.vars(expr))
	wrapped <- list()
	for (fun in funs) {
	fun_env <- environment(get(fun, envir = parent.frame()))
	if(is.null(fun_env))
	namespace <- "base"
	else
	namespace <- getNamespaceName(fun_env)

	# Run as awk -v x=xyz ... or env variables for stuff?
	# Assumptions: the data is evenly spaced along the x-axis
