Cybernetic Programming

cybernetics

I’d like to make a proposal for a new kind of programming (at least new to me, LOL). When I was studying back in the nineties I became interested in something called ‘sociocratic organization‘. This is a form of organization based on Cybernetics. Cybernetics is the study of systems with feedback loops. When you think of a thermostat in the room, it has a feedback loop. When it gets too hot, it cools, when it gets too cool, it warms up, and that way it keeps the system in balance. In computer programming we don’t deploy such features normally. We pray that all goes well, and that we didn’t forget anything, and if it does go wrong, the whole system usually crumbles apart. In web programming that’s usually a minor glitch, since just one page of our whole system breaks. In desktop computing it’s much worse. And in embedded programming it’s disastrous. Now instead of writing numerous unit tests, or mathematically proving our program, perhaps it would be possible to use this idea of a feedback loop in many aspects of our programming.

Consider you have to write a program that is to determine the best results for a search, similar to Google (but not as vast, so let’s say a small web site). We need to display what’s relevant to the user, but we don’t know what is relevant. So you just do a simple text search to find a record within a table. Now you check which of the results is clicked for this particular search result, and then you log the search term, and with it the clicked result.

Then a new user shows up and does the same search, and clicks the same result. You increment the counter for this result on this search in the log. After a while we should see our statistics in the table represent what people were searching for, and which records were ‘successful’ to them (at least they clicked it). Depending on these results you can now decide to alter the order of the search results, where the highest scoring record is put on top of the search results page.

Pretty nifty. I Googled it and found that Microsoft Research has written a paper on something similar. So expect this to Bing us soon.
