The fpcomplete case studies are similar to what I'm looking for. Anyone have more of them? Maybe a blog post or comparison they've written? Thanks, wrote: > Hi Nick, > > FP Complete has a lot of good resources on this topic, including some case > studies: https://www.fpcomplete.com/business/reso

[Haskell-cafe] FP Complete competition clarification

2013-09-26 Thread Mike Meyer
I got some clarification on what "unpublished" means for FP Complete competition entries. Basically, you can enter code that you've already published, providing it has an appropriate license (or can be republished with such a license). The tutorial/description/documentation that shows how to use i

Thank you, Mike. This is definitely not the answer I got when I contacted FP more than a month ago. It's good to see that they are broadening the definition :) On 26 September 2013 18:35, Mike Meyer wrote: > I got some clarification on what "unpublished" means for FP Complete > competition entr

[Haskell-cafe] Proposal: RankedInstances

2013-09-26 Thread Wvv
The main power of Haskell is on instances. But Haskell instances system work fine with lower number of instances (rare instances). But we want hight density of instances! If we wish to have more selective instances we use `OverlappingInstances` (which are desined in a poor way) and if we still hav

Hi Conal, I'm glad you're bringing this up. I am currently working on FLTK bindings ( github.com/deech/fltkhs). It's main advantage of this toolkit is that it lets the user deploy apps as a self-contained binary on all platforms. Right now the work consists of the tedium of binding Haskell to the

Hi Conal, If there is a system like you describe, I'm not aware of it. Part of the problem is the state of the underlying C libraries: gtk+ - possible, but suffers from the drawbacks you mention on OSX and is reportedly difficult to install on windows wx - somehow I've never been able to build t
