Color the Solitaire board as follows, abc bca abcabca bcabcab bca cab Let A, B, and C be the number of pegs that have color a, b, and c, respectively. Every move replaces a peg of two of the colors by a peg of the third color. So no move changes the parities of A+B, B+C or C+A. Now for your example, A+B, B+C and C+A are initially even. It's easy to see that with a single peg left two of these numbers must be odd, and therefore there is no solution.

Hi again,
I'm thinking: if this all is about a small file, addtags.idl which is
generated in some unusual way, I might just add it to the
distributable source tree, and then nobody would have had problems
with ${var:m:n} substitution.
Thanks.

Re: [Haskell-cafe] An interesting monad: "Prompt"
Also, I didn't realize this at first, but in order to use any of the MonadTrans instances, like having StateT s (Prompt p) automatically be a MonadPrompt, you sadly also need "-fallow-overlapping-instances". This is because MonadTrans monads looks a lot like Prompt. arbitrary MonadTrans monad: t (m :: * -> *) (a :: *) Prompt: Prompt (p :: * -> *) (a :: *) Since you can substitute "Prompt" for t and rename m to p, they look like they match the some of the same types to the compiler. However, since Prompt won't ever be declared as an instance of MonadTrans, the overlap is safe. The alternative is to declare all the instances you need manually: instance MonadPrompt p (StateT s (Prompt p)) where prompt = lift . prompt -- etc. -- ryan ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Re: [Haskell-cafe] problems building ycr2js
Thanks Brandon. I'm on ubuntu feisty.
This breakage is a manifestation of
https://bugs.launchpad.net/ubuntu/+source/dash/+bug/61463
Basically, feisty switched the default shell to "dash" (which I'd
never heard of) from bash, because dash runs faster. But it's not 100%
compatible.
This was very controversial, but it appears that the feisty devs are
not amenable to switching /bin/sh back to bash, despite massive script
breakage, because using dash as default saves them tim. I must say, I
disagree with this move; and feel a bit let down by a distro that
overall has been very good to me.
Feisty devs suggest people fix the underlying problem, which is that
/bin/sh should not assume bash as default, but specify bash
explicitly. So I guess this is what should be done in the case of
building ycr2js; either that or make it dash compatible.
I will try to fix this myself by editing the makefile. I'll also
volunteer to the buildbot.
FWIW, this shouldn't affect ubuntu dapper (long term support) as they
still do the expected thing with sh.

[Haskell-cafe] Libraries need a new owner
Hello Folks, As some of you will be aware, I have been working on various Map implementations that currently live here.. http://code.haskell.org/collections/collections-ghc6.8 The libs in question being Data.Tree.AVL, Data.Trie.General and a few other bits like Data.COrdering and the AVL based Data.Map/Set clones. Well, I have decided to stop work on these. So they need a new owner if they're going to go anywhere. If anyone is interested in the job then I suggest they contact myself or Jean-Philippe Bernardy. Of course I will be happy to provide any help or advise anyone who takes over these libs may feel they need from me. I might even contribute a few patches from time to time myself :-) Thanks -- Adrian Hey ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
