I just wanted to say I agree to everything you just said. I don't feel like I've heard this viewpoint expressed better before.

To ease your Haskell experience consider using LTS Haskell or Stackage to avoid Cabal hell: https://www.fpcomplete.com/blog/2015/01/announcing-lts-haske... http://www.stackage.org/

Not the parent, but I made the same transition a couple of years ago. I emailed you something I've wrote in Haskell that might be relevant to you but didn't want to publicize too much yet.

This can be true, but with discipline you can use superior technologies that may not quite be as popular as Java/C/Javascript/PHP but have all the libs needed for your use case.

I actually did the exact same thing a couple years ago. > cabal hell can really suck Agreed, prepare to be happy: https://www.fpcomplete.com/blog/2015/01/announcing-lts-haske... > Haskell takes much lon

Think about how that would have changed if they had a simple text editor with parenthesis highlighting.

Xmonad is buggy? I've been using it for 4 years and never had a problem. I actually also use it on multiple displays.

Good point.

Thanks, I forgot about the warnings. It's been a while since I've used Go.

by codygman 12y ago
In the rust example error handling is enforced via the type system whereas with Go it depends on your (and others) discipline.

I don't think I'd call the IO monad "dirty" since it's still pure. Also "dirty" make it sounds like a hack.

You'd probably enjoy Haskell more than Go as a Rubyist imo. Most Rubyist I've known seem to really like Haskell.

I wonder how long it will be until Rob Pike decides that "Handling error values should be enforced by the type system".

What about this Haskell example doing the same tasks? https://news.ycombinator.com/item?id=8878421

I linked a Haskell version above as well: https://news.ycombinator.com/item?id=8878421

Here's the Haskell equivalent for anyone curious (Beware of curry[0]!): data Article = Article { title :: String , author :: String , tags :: [String]

Python is being hurt by Python 3.0 changing so much.

spacemacs looks amazing, thanks for that!

by codygman 12y ago
That sounds like something you'd use the state monad for if I understand correctly. Can you provide an example of semi unification where Haskell would be not so great?
744.
by codygman 12y ago
I believe spacecowboy_lon is referring to functions opposed to methods. For those that don't know the difference a method is basically a function that has access to the state of an object (correct me if my definition is wrong or sucks)

by codygman 12y ago
In at least two of your examples you could pass in an error handling function (or class) and it would still be a net win. Analyzing this further would require having a more fleshed out example.

by codygman 12y ago
That would be very interesting to see!

by codygman 12y ago
For me: I can hack something together quickly cutting corners if needed, then refactoring is easy and almost always works on compile when you get around to fixing things up.

by codygman 12y ago
It would most likely be in the IO monad since IO would be happening. As for whether monads would help your code (and I still think they would) I'll need a larger example. In a small example abstraction and reuse aren't really appa

Yeah, a bsd-licensed Shen is something I'd be interested in as well.

Cool, now we have something to work with. However at such a high level no paradigm's differences (much less pros/cons) would be apparent. Would you mind implementing those individual functions? Actually it might be easier to use s
