As for as the amount of messages, who cares. Right. So the question is, what is (or should be) the contents of the messages that are posted only to haskell@, but *not* crossposted to café? Because I think this set of messages is (or should be) empty, which suggests that we 1) remove the people subscribed to haskell-cafe@ from haskell@ 2) automatically post all messages to haskell@ to -cafe as well 3) post announcements to haskell@ without any crossposting. This way, most people will subscribe to -cafe and get a single copy of each message, not miss out on any important stuff, and as an added benefit discussion will mostly go to that list. People who only want low-bandwith subscription to announcements, HWN, and the like, may subscribe to haskell@ only. -k -- If I haven't seen further, it is by standing in the footprints of giants ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Incidentally, I've always wondered about the politically correct way of referring to this programming language (and related implementation in the above-mentioned type system) in academic circles; Is this a question of politically correctness? Since there's no discrimination or prejudice involved, I think it's more of a question of social rules. If you are using a word where it's going to be indexed, like article titles, I vote for beeing accurate. But outside that, it's difficult to answer this in a way that extends beyond one's own circle of friends. Censoring a bad word may be polite for some, and offensive for others, what could we do about that? Regarding brainfuck itself, I think beeing censored is part of the joke. In general, if a programming language-related term contains what is generally regarded as a profane word as a component, for what kinds of written material should I prioritize accuracy vs. propriety? If we decide to allow * inside conids and varids in Haskell, and have a rule that names clash when they differ only by a letter replaced by a *, we have gone too far.

I censored it because I intend the HWN to be a PG rated article. I figure -- while I am not under any delusion that kids these days have mouths fouler than mine, which is a feat for sure -- that some young programmer with strict speaking morals may stumble upon the HWN and say, Hey self! This is a fantastically written weekly newsletter concerning recent developments in this community, and did I mention how wonderfully written it is? I should want said programmer to not feel any offense that can be easily avoided by a single * here or !...@#$ there. Generally I'm opposed to censorship -- but that generally entails an authority censoring against the will of the author, I think that in this case -- as I am the author/editor (not of the post proper, but rather the conduit to the post) -- that censorship-self-inflicted doesn't really count. I guess my view is that such a paper with an unintentionally foul- mouthed name -- like Brainf*ck -- ought not be the reason for which your paper is rejected from a journal or other publication source, but rather it should be understood that it might be mildly censored (as I did) if it is publish, in accordance with the intended audience of the publication source. /Joe On Nov 23, 2009, at 9:35 PM, Benjamin L.Russell wrote: On Sat, 21 Nov 2009 12:14:29 -0800 (PST), jfred...@gmail.com wrote: Typef*ck: Brainf*ck in the type system.

In addition (just to be pedantic, but this issue could conceivably arise with certain library names in the future), if the library were announced on, say, the main Haskell mailing list, then for that intended audience of the publication source, should the subject line of the announcement read ANN: Monadam*: A Library for Translating Those Dam* Monads into Non-monad-syntax Form, or would it be more appropriate to leave the library name intact? Normally, this issue does not arise, but with certain programming language names that contain profane terms within, there is a possibility that somebody could potentially name a library similarly, leading to this referencing issue. Presumably, the Library of Congress citation would include the full name, regardless of any profane terms within; if the name were censored to be politically correct, and then some researcher wanted to look up the Library of Congress citation, couldn't the censoring potentially lead to referencing difficulties? For a researcher potentially wishing to look up a publication, this could become an issue. How should this issue be resolved? -- Benjamin L. Russell -- Benjamin L.

Inaccuracy in the title can potentially lead to cross-referencing difficulties if a search is performed. As long as the title is in quotation, it would seem that accuracy should probably be prioritized over the political incorrectness of portions of the title, so that someone who wishes, say, to perform a search need not search for both versions of the title.

If someone were, say, a functional programming researcher and wanted to look up related discussions in archived mailing lists and newsgroups on a term that included a politically incorrect subterm within, then it would then be necessary to perform a search on all the following variants (taking Monadam* (with the asterisk replaced by the the correct letter) as an example): 1) the uncensored version 2) Monadam* 3) Monada** 4) Monad*** 5) Mona Wow. Unfortunately, the automated filtering software is likely to mark a message of an uncensored title as spam.

Take for example the IRC bot example ( http://www.haskell.org/haskellwiki/Roll_your_own_IRC_bot) listed below. Is there any insight to be gained by theorem proofs (as in COQ) into the app? Yes. Basically, if you can prove that the program is correct, then you don't need to test it. While proofs can become very tedious for huge programs with many different kinds of control flow involving very complicated logic, if the program size can be shortened to a reasonable size, then proofs can help shorten development time. This was actually part of the motivation for developing Haskell as a pure functional programming language (i.e., one that prohibits side effects -- see http://www.haskell.org/haskellwiki/Functional_programming). It is generally easier to write proofs for pure functional programming languages than for impure ones. Theorem provers help to automate the process of writing proofs for programs. Djinn (see http://lambda-the-ultimate.org/node/1178) is an example of a theorem prover for Haskell. Given a (Haskell function), it returns a function of that type if one exists. Here is a sample Djinn session (courtesy of http://lambda-the-ultimate.org/node/1178): calvin% djinn Welcome to Djinn version 2005-12-11. Type :h to get help. # Djinn is interactive if not given any arguments. # Let's see if it can find the identity function. Djinn f ? a-a f :: a - a f x1 = x1 # Yes, that was easy. Let's try some tuple munging. Djinn sel ? ((a,b),(c,d)) - (b,c) sel :: ((a, b), (c, d)) - (b, c) sel ((_, v5), (v6, _)) = (v5, v6) # We can ask for the impossible, but then we get what we # deserve. Djinn cast ? a-b -- cast cannot be realized. # OK, let's be bold and try some functions that are tricky to write: # return, bind, and callCC in the continuation monad Djinn type C a = (a - r) - r Djinn returnC ? a - C a returnC :: a - C a returnC x1 x2 = x2 x1 Djinn bindC ? C a - (a - C b) - C b bindC :: C a - (a - C b) - C b bindC x1 x2 x3 = x1 (\ c15 - x2 c15 (\ c17 - x3 c17)) Djinn callCC ?

Djinn :q Bye. Other theorem provers include COQ (see http://coq.inria.fr/) and Sparkle (see http://www.cs.ru.nl/Sparkle/) (a theorem prover for the alternative non-strict, purely function programming language Clean (see http://clean.cs.ru.nl/)). -- Benjamin L.

A more difficult question is: how do I know that the formal specification I've written for my program is the right one? Tools can fairly easily check that your programs conform to a given specification, but they cannot (to my knowledge) check that your specification says exactly what you want it to say. The key is *redundancy*: as long as your property is sufficiently different (in structure, in authorship, etc...) you can hope that if the spec has a bug, the code will not have a corresponding bug and vice versa. It's only a hope, tho. Stefan ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

It's only a hope, tho. There are other meta-level properties one might desire in a specification, too, such as: * Simplicity - if a specification is too long-winded, you might not spot a bug in it because it's too hard to read. * Definite description - if a specification is a definite description, it is satisfied by one and only one value (up to functional equivalence). For example, if I say that a list sorting function must preserve the length of its input, that's not a definite description, because it is satisfied by the identity function, as well as a correct sorting function. However, if I say (in a suitably formal way) that a sorting function must output a list where every element in the input occurs the same number of times in the output as it occurs in the input, and vice-versa, and the output is ordered according to the specified order - then that *is* a definite description, because any two functions that follow that specification must be equivalent. * Reusable (and perhaps reused!) - As in ordinary programming, reuse of specifications can help avoid errors. -- Robin ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I have been reluctant to subscribe to the café due to the volume of messages. Instead I tend to occasionally browse the archives. Needless to say your questions eluded me until now. The same is true for Mike Gunter's message[1] which I will respond to presently. How is it related to this one: http://www.haskell.org/haskellwiki/Dimensionalized_numbers ? I ashamedly admit that I am guilty of inventing my own wheel. I haven't looked too closely at Aaron's code but I believe there are some conceptual similarities. Regarding completeness user my library supports all seven base dimensions while Aaron's library currently supports only length and time (I believe it is meant as a proof of concept (toy example in his own words) rather than a complete library). My ambition is to provide a reasonably complete library. It should certainly be mentioned on http://www.haskell.org/haskellwiki/Physical_units http://www.haskell.org/haskellwiki/Libraries_and_tools/Mathematics#Physical_units I have added it to the above pages.
