Re: [Chicken-users] endian-port

Hello, Actually, the endian-blob egg in Chicken 4 is meant to take over the functionality of endian-port. Your port of endian-port would probably have to rely on the wrappers generated by swig, which are not especially readable or maintainable. Unfortunately, I don't have Chicken 3 installed

Re: [Chicken-users] Computational geometry for chicken?

Hello, Are you really sure that you need a library that is as general as CGAL? Perhaps you should start by defining the exact requirements of the application you are interested in, and that should guide you in determining what kind of data structures and algorithms you need. For example, if

Re: [Chicken-users] How to report a bug?

Hi Jeronimo, Just before where it says you must fill in your name and e-mail address, it says that you must email me to register a username and password on the Chicken Trac instance. So send me your preferred username and password encoded with htpasswd (or in plain text), and I will set up the

Re: [Chicken-users] Computational geometry for chicken?

Hi Matt, I am not an expert in the field, and I am not at work, so my access to scientific journals is limited, but a quick and careless Google search reveals several papers that discuss efficient set operations on polygons using quad trees: _Using quadtrees to represent spatial data_

Re: [Chicken-users] Was crunch really discontinued? Is there an alternative?

Hello, If matrix multiplication is what you are interested in, then you could consider using the Chicken bindings for the BLAS and ATLAS libraries: http://chicken.wiki.br/eggref/4/blas http://chicken.wiki.br/eggref/4/atlas-lapack -Ivan Jeronimo Pellegrini j...@aleph0.info writes:

Re: [Chicken-users] Re: chicken-install should use sudo -v

I agree that chicken-install should not use sudo. The implicit invocation of sudo violates the principle of least astonishment, and presents a potential risk for users who do not understand the security implications of this approach. I opposed the inclusion of the sudo mis-feature in

Re: [Chicken-users] Bignums in core

I agree that bignums do not automatically equal slower (fixnum) performance. For example, see here: http://people.csail.mit.edu/jaffer/CNS/interpreter-branch Also, the Glasgow Haskell Compiler wiki has some notes on replacing GMP: http://hackage.haskell.org/trac/ghc/wiki/ReplacingGMPNotes

[Chicken-users] Chicken pre-release 4.2.0

Hi all, I have merged Chicken trunk with the prerelease branch in the SVN repository, and I plan on making release 4.2.0 of Chicken within a week from today. This release will be based on development snapshot 4.1.9, but including the topological-sort procedure and some bug fixes to

Re: [Chicken-users] Proposed procedure movement in Chicken 4

Hi Kon, Good idea in principle. Unit extras and utils should be dissolved altogether, if possible. Can I ask you to wait until Chicken 4.2.0 is released? I will merge trunk into the prerelease branch this weekend, and start testing it, so if you can start making your changes to trunk after

Re: [Chicken-users] Scheme Steering Committee Questions

Hi Kon, I would be curious to know what their position is on the SRFI process with respect to the Scheme standard. R6RS is deliberately incompatible with SRFI-1, and I see this as an attempt to subvert the SRFI process. Does the current Scheme Steering Committee consider it necessary to

Re: [Chicken-users] Chicken 4 development snapshots

I don't know enough about how the RSS feeds are constructed to answer this question. I will have to discuss with Mario and see what we can do. I can only say that there will have to be a separate run of Salmonella for Chicken 3 and 4, respectively, but I have no idea how the build logs are
