lisp macros, Racket define syntax rule and pattern matching

racket named lisp defmacro as define-syntax-rule. A step forward. Even better is “define-form-rule”, as lisp macro can't change syntax. that how it calls macros as pattern matching and or syntax my 20+ of computing career, the Common Lisp fanatics, are the most persistent idiotic bunch.racket, now i've read most of its doc, clearly tried to fix many of Common lisp's bad persistent notions, and scheme too.scheme lisp lot is a unfortunate sorry lot. Cult result is obsession with tail recursion, like haskell's monad. Going nowhere, forever.the most idiotic feature in comp lang, is call-with-current-continuation of scheme fame. This, rivets scheme in lala-land forever.

language popularity ranking sites

there's many language popularity ranking sites. The most well-known, is tiobe. think TIOBE index is stupid. Their approach is not good. Mostly because, they tried to be general, as if they know what “popularity” means.another one,, is worse. And badly maintained.the following is better, because they are specific on what they measure. language popularity is a lose concept. Is it more talked about? is it more used? more used by companies or by loud amature programers? Is it more existing code? How do you count code? What about quality code, but are not public?

Google Puts All 9 Million Source Code Files in One Repo

The Motivation for a Monolithic Codebase Why Google Stores Billions of LinesPublished on Sep 14, 2015 This talk will outline the scale of Google’s codebase, describe Google’s custom-built monolithic source repository, and discuss the reasons behind choosing this model of source control management. It will include background on the systems and workflows used at Google that make managing and working productively with a large repository feasible, in addition to a discussion of the advantages and trade-offs of this approach.Presenter: Rachel PotvinGoogle Puts All 9 Million Source Code Files in One Repo. Its own custom source management system called piper.for context, linux kernel has 15M lines. Google repo has 2G lines. Google human makes 15M lines of code change per week.Rachel Potvin explains why. But, i'm rather not convinced. Are you?
