Praising MJD

Mark Jason Dominus is one of those guys that is worth following everywhere in the net.

• Web: His site is quite old school. It reminds me of c2, or norvig.com, that have really old look but is full of insights and no-bullshit content. Also, loads instantly.
• Blog: Wide range of topics. From systems programming to functional programming, haskell, monads, git, books, alien codes, mathematics.... 
• Book: Higher Order Perl is a great book on functional programming. It uses Perl, but the concepts are really language agnostic. It clearly follows a similar approach to SICP, maybe with a more practical approach.  Higher Order Perl is on my top 10 list of tech books. Top5 if we exclude lisp books.
• Talks: He excels at giving talks also. There are very nice talks about. 
• Systems programming (also, unix process model, unix history, )
• Hash tables
• Parsing combinators
• Programming red flags
• Perl pseudohashes. Nice story of an un-feature 
• Giving talks tips
