Welcome to issue 248 of the HWN, an issue covering crowd-sourced bits of information about Haskell from around the web. This issue covers the week of October 14 to October 20, 2012.
Quotes of the Week
- shachaf: Don't fixity fit ain't broken.
- shachaf: SIKP, the cheap knockoff book that uses the less-known programming language "skeem"
- shachaf: category-extras was so great until the antitrust lawsuit.
- Cale: If there was a second syntax and we named it cata' would that be a catastrophe?
- acowley: I just don't want edwardk to name them, because he'll choose a name like "x"
- cmccann: so edwardk has abstracted things to the point where you can use his libraries without even installing them
- Jafet: Agda has an evaluator?
- johnw: but probably the other package is more "idiomatic". if by that you mean "uses mathematics to such a degree that most people walk away in consternation"
- copumpkin: if I throw enough CT terms out there, one of them is bound to be right eventually
- spj: "Our imperative colleagues do a lot of reasoning about their systems. Well, they have to."
- spj: "You do the category theory, and you talk to Gordon. And he talks to Phil. And Phil talks to me."
- ciaranm: a confusion is just the categorical dual of a fusion, which is just a fusoid in the category of brainofunctors
