Haskell Weekly News: Issue 316

Welcome to issue 316 of the HWN, an issue covering crowd-sourced bits of information about Haskell from around the web. This issue covers from January 18 to 31, 2015

After doing more than 150 of these, I have come to the conclusion that it is time for me to take a permanent break from HWN. I realize that "we could do better", and have something a bit more edited than a collection of links, and some quotes. I wish I had more time to devote to such endeavor, but my time is currently being taken up by trying to help my 1 year old explore her little world.

If you'd like to be the one to continue the long tradition of HWN, drop me a line.

Thanks for following along for the last 3 years!

Quotes of the Week

• spopejoy: That [Spineless Tagless G Machine] will always sound like the villian in an upcoming Ghostbusters sequel to me :)
• pigworker: When you can make data out of potatoes, why would you want to encode them as functions?
• fishcorn: When someone mentions lens on freenode... zeus-lens!
• neelk: So constructively we know this style can be used to meet hard performance deadlines in domains where the penalty for failure is literally radioactive flaming death.
• edwardkmett: At one point we had a type in lens where one of its arguments started taking parameters of the form i m a s t a b u. Upon reflection, we let it win the argument and decided not to implement the function.
• Ivan Appel: ... while the popular opinion says that the main reason to pick Haskell is "to have fun hacking," in fact it's not so fun to hack in Haskell because there's not such much hacking to do at the first place. For instance, you don't need to spend lots of effort tracing and fixing obscure bugs, so if your definition of "hacking" includes heroic bugfixing, you'd be better off with JavaScript or Perl.
