Issue 61 :: Haskell Weekly

\/\/ Issue 62
<https://haskellweekly.news/issues/62.html>

Welcome to another issue of Haskell Weekly! Haskell is a purely
functional programming language that focuses on robustness, concision,
and correctness. This is a weekly summary of what's going on in its
community.

## Featured ##

- YOW! Lambda Jam 2017
  <https://www.youtube.com/playlist?list=PLIpl4GKFQR6dqCNb2J0eQFR21Lwnk4I86>
  Videos of 23 talks by Edward Kmett, John Hughes, Conal Elliott, Brian
  McKenna, Bodil Stokke, and others.

- Perhaps not the answer you were expecting but you asked for it
  <https://personal.cis.strath.ac.uk/conor.mcbride/so-pigworker.pdf>
  A collection of Conor McBride's Stack Overflow answers.

- Unit testing effectful Haskell with monad-mock

  > While monad-mock might not be anything drastically different from

  > complex interactions with other services and systems.

- Front Row is hiring a senior backend Haskell engineer (ad)
  <https://frontrow.workable.com/j/463B843754>
  > Come change how 6.5+ million K-12 US students learn Math, Language

- A major upgrade to Megaparsec: more speed, more power
  <https://markkarpov.com/post/megaparsec-more-speed-more-power.html>

- Derive instances of representationally equal types
  <https://gist.github.com/Icelandjack/d258b88a0e0b3be2c0b3711fdd833045/fe806ce795006be545833742dd1bdcdc31738ca5>

- New version of FLTKHS with much better error messages and OpenGL
integration

  <https://www.athiemann.net/2017/07/02/superrecord.html>

Despite the fact that this is just a loose collection of answers without a
lot of context (e.g. the questions which were answered are missing), I very
much enjoyed reading it. I like the way in which Conor manages to discuss
beginner-level questions as well as more advanced topics using simple
language but without sacrificing correctness.

Maybe he could be bribed into writing a book in this theme, various assorted
topics much as in the style of Scott Meyers' "Effective C++" books? I'd
certainly benefit and buy it. :-)
