Re: [Haskell-cafe] haskellonline.org, a web frontend for ghc
That´s very good. What tecnology, libraries etc did you use? 2012/5/3 Gintautas Miliauskas gintau...@miliauskas.lt: Hello, check out http://haskellonline.org, an online Haskell typechecker. It is essentially a thin web wrapper over ghc, but it takes some friction out of learning Haskell, if only because no local setup is required. It is a weekend's work, so do not be too harsh, but feedback is welcome! I have also written up an accompanying blog post [1].

Re: [Haskell-cafe] Haskell and arrays
Well actually, unless you _really_ need paramterizable indexes (i.e. not only Ints) I don't see reasons to prefer array to vector now. 2012/5/4 Johan Tibell johan.tib...@gmail.com Hi Morten, If speed is really important I would go with the vector package. It has a more modern API and better performance. -- Johan ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Dear Kazu, Could you please answer my concerns about the license under which LYAH is distributed?

Re: [Haskell-cafe] MonadError vs Control.Exception
On 12-05-04 07:03 PM, Станислав Черничкин wrote: Hi, guys, I'm interested in best practices in using of each approach. Personally I like MonadError because it is more explicit and Control.Exception-s becomes really ugly in complex scenarios. [...] User has to deal with both, but have no evidence on none of them from type signatures or documentation. My opinion is largely recorded in my sarcastic http://www.vex.net/~trebla/haskell/exception.xhtml Be sure to click the click me if you can button and read again. My sarcastic article focuses on control flow and doesn't comment on types. I agree about seeing exception possibilities in types. But that was done 8 years ago: http://www.haskell.org/pipermail/haskell/2004-June/014271.html So, I hate exceptions, I blame it, I think exceptions is junk came from OO-world and horrible languages like C# or even more horrible like Java, and it should be wiped out from Haskell with fire. But it is only my humble opinion. While you are entitled to have opinions, and I am fine with those parts about I hate exceptions, exceptions is junk, it is irresponsible and unreasonable to use that right on objective, verifiable, historical facts. Yes, I really hate it when people do that. I think Oleg is from Vulcus without even asking anyone. I think everyone uses Java without hard data. Programmers' habit of subsituting thinking for empirical facts is one of many reasons why the software profession has not yet earned the engineering status. The only two responsible, reasonable positions are: 1. find the answer or 2. hold the position that you just don't know Exceptions appeared as early as in ML and Ada in the 1980s, before many people knew OO, before ML or Ada got OO stuff, before Java or C# existed (or when Java was an internal project under two old names at Sun), even before C++ got exceptions. Exceptions first appeared under another name in the paper of David Parnas and Harald Würges response to undesired events in software systems in ICSE 1976. Exceptions did not come from OO or languages you mentioned, and this is not about opinion. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Re: [Haskell-cafe] Learn you
Hello, Could you please answer my concerns about the license under which LYAH is distributed? (see my initial reply to the thread) Additionally, under what license is your translation work re-distributed? What I know is: - The Japanese publisher bought the translation license from the publisher of the original. - The original author knows this. - Translation is based on the original published book, not on the online version. They are different because editors modified much. - I don't think the Japanese publisher open the translated book on line. P.S. I'm not a translater of this book. I'm the translator of Programming in Haskell. :-) --Kazu ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
