This talk was presented at LambdaConf 2017. It is based on my presentation of the same name, initially a lightning talk at ILC'2009, then grown into a presentation at Bay Area Lispers 2009, < http://fare.tunes.org/computing/bal2009.pdf > then made part of a presentation at LispNYC in October 2014: < https://vimeo.com/152109286 >
I also wrote an article that I submitted to SNAPL 2015, but it was rejected, having offended a reviewer by presenting free software as an improvement over proprietary software without qualification: http://snapl.org/2015/cfp.html
