search for: multimethod

I'm working on implementing a simple functional language in LLVM. It's statically typed, but I'd like to a have some simple multimethods involved. Does LLVM have some intrinsics for handling something like C++ vtables? Or do I need to implement my own way of handling single-dispatch functions? Thanks, Timothy -- “One of the main causes of the fall of the Roman Empire was that–lacking zero–they had no way to indicate successful...

...ch between the (rather ambitious) Fortress type system and a virtual machine not designed to support it (that would be every currently available VM, not just JVM). In addressing these challenges, we learned a lot about the implications of the Fortress type system for the implementation of symmetric multimethod dispatch, and have concluded that we are now unlikely to learn more (in a research sense) from completing the implementation of Fortress for JVM."

I created a subversion repository on my new vps and i''m trying to setup my rails app there. However i keep getting this error: subversion/libsvn_subr/io.c:2516: (apr_err=13) svn: Can''t create directory ''/home/svnadmin/rapleaf/db/transactions/0-1.txn'': Permission denied How do i fix this? I know others have had this before, so i would appreciate some help.

I started with Ruby on Rails in the 0.13.x period, so I''m sure I missed out on a lot of history. There''s probably some good explanation for something I''ve been wondering about, but I haven''t seen it written down anywhere. Maybe someone can clue me in. I''ve always felt that one of the uglier APIs was the ActiveRecord::find() method. I call

Dear R users, I am trying to simulate some multitrait-multimethod models using the packages sem and psych but whatever I do to deal with models which do not converge I always get stuck and get error messages such as these: "Error in summary.sem(M1) : coefficient covariances cannot be computed" "Error in solve.default(res$hessian) : System ist f?...
