Welcome to issue 293 of the HWN, an issue covering crowd-sourced bits of information about Haskell from around the web. This issue covers from April 20 to 26, 2014
Quotes of the Week
- monochrom: linux's ulimit for main memory will not help because linux kernel's allocator is a lazy yes-man (think irrefutable pattern)
- edwardk: lens is the only library I've ever written that generates hate mail and invites to give talks in almost equal measure
- shachaf: You don't need lens to produce or consume lenses. You just need it to complain about them.
- glguy_: Reddit has shown you don't need to have used the lens package to complain about it, either
