defining r audio connections
...ude/R_ext/Connections.h
I'm not sure of a good pedagogic example; people who want to write their own connections usually want to do so for complicated reasons!
This is my own abandoned attempt https://github.com/mtmorgan/socketeer/blob/b0a1448191fe5f79a3f09d1f939e1e235a22cf11/src/connection.c#L169-L192 where connection_local_client() is called from R and _connection_local() creates and populates the appropriate structure. Probably I have done things totally wrong (e.g., by not checking the version of the API, as advised in the header file!)

defining r audio connections
Dear R Devel,
Since Linux moved away from using a file-system interface for audio, I think it is necessary to write special libraries to interface with audio hardware from various languages on Linux.
In R, it seems like the appropriate datatype for a `snd_pcm_t` handle pointing to an open ALSA source or sink would be a "connection". Connection types are already defined in R for

default min-v/nsize parameters
Just wanted to start a discussion on whether R could ship with more
appropriate GC parameters. Right now, loading the recommended package
Matrix leads to:
> library(Matrix)
> gc()
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 1076796 57.6 1368491 73.1 1198505 64.1
Vcells 1671329 12.8 2685683 20.5 1932418 14.8
Results may vary, but here R needed 64MB of N cells and 15MB

to_json performance
Originally posted on github, reported to the right place.
I would like to open a discussion about how `to_json` and `as_json`
operates in Rails from a performance standpoint.
I''m using Rails 3.2 but this issue applies to almost all versions of
Rails.
Our use case presents the challenge in sending out potentially large
JSON (or XML, but we''ll focus on JSON rendering here)
