Donald Knuth once said, “Premature Optimisation is the root of all evil!”
But that message has obviously not yet reached the Racket community.Because how else do you explain this madness: they spent three years developing a new version of Racket that et the end turned slower than the original! [1]Meanwhile, for example, we can still count the number of web applications written in Racket on the fingers of one hand, and the number of Racket users in the racket group is rapidly decreasing from day to day.Turns out the only users of Racket are people who live off Racket in a way that writes scientific articles that nobody cares about.Very rare are those who use Racket for any practical purposes.I wonder if it would have been better if this huge effort had been made to write clear documentation on how to use the Racket Web Library in a practical way? The current documentation for the web framework doesn't understand, I mean, even its creator, Jay McCarthy. I've never seen worse documentation on any software product than this for racket web library in my entire life.On the other hand, we have this guy, Jess Alama [2], who, like, wrote something about it. But there's literally not a single thing this guy published that he didn't charge her fattly. All his books and tutorials cost a lot and their quality is questionable.But, unfortunately, these topics are a taboo in Racket community...[1]
