The number and duration of queries per-page is killing us. So we're thinking of using a caching layer like memcached. Except we'd like something more sophisticated than memcached. Allow me to explain. memcached is like an object, with a very limited API: basically #get_value_by_key and #set_value_by_key. One thing we need, that is not supported by memcached, is to be able to store a large set of very large objects, ...http://www.sagewire.org/ruby-programming/memcachedlike-server-in-Ruby-feasible-1998879.aspxrss@sagewire.orgSun, 28 Oct 2007 22:07:16 GMThttp://www.sagewire.org/ruby-programming/Duplicate-elements-in-array-1999424.aspxHello I am trying to output the duplicate elements in an array.

Everyone relates it to smalltalk, and that seems mostly true. Being a Certified Old Dude (and sometimes a quant-heavy economist), it does remind me of the pleasurable experience of learning serious programming tripping along with smalltalk on one end and various lisp incarnations on the other, circa xerox/parc days.

The tools I'm familiar with are mkmf.rb and setup.rb. I have gotten the sense that mkmf.rb may still be used, but that setup.rb may have been replaced by some more powerful rake-based automatic gem building solution? Anyway, any tips, hints, or links'd be appreciated!Thanks, Billhttp://www.sagewire.org/ruby-programming/State-of-the-art-in-setuprb-land-1997067.aspxrss@sagewire.orgFri, 26 Oct 2007 06:32:49 GMT
