We need more standard special purpose interfaces. Not unstructured RPC protocols, but very specific "Every plugin of this type has this function that does exactly this" kinds of things. Linux people seem to tolerate bash partly because they DO have a special purpose modular system. They algorithmically manipulate text in batch rather than realtime mode to produce an output on a regular basis(I'm not sure for what, besides compiling and building, but they all say they have use cases). Apparently it works great if you process lots of text files. Perhaps a GitHub awesome list. I've been meaning to start one for very common standards in general(18650 batteries, tripod thread, etc). We have LADSPA and LV2 for audio, shell commands for text, etc, What else do we have, and what should we have?
