  _No_ Ruby Weekly News 20th - 26th February 2006

   Tim S. announced a week without Ruby Weekly News.
   (Hey, that was last week.)

   Did you know that anyone can contribute to the next newsletter,
simply by
   going to, clicking the "contribute" button,
   then summarising a few threads?

   It's especially helpful now that there are SO MANY threads every week


   A question was asked about "Capistrano", which provides this
   with an excuse to note that this is the new name of SwitchTower.

   The renaming is due to an unpleasant company sending a Cease & Desist
   letter to Jamis B., saying they have a trademark on "SwitchTower"
   (apparently they have a product relating to web conferencing that
   what they call a "SwitchTower Network").

  AJAX Patterns Blog

   Pat Eyler:
   > Christian Gross, the author of AJAX and Best Practices, runs a blog
   > and has started a poll asking which
language he
   > should port his AJAX patterns to next. (They are currently
available for

   > If anyone's interested in seeing Ruby up next, you might head over
   > the blog and cast your vote.

   Three days later there was a new post on Christian's blog, wondering
   was going on. The poll went from 10 votes total, with PHP leading, to
   than 150 votes, 91% of which were for Ruby.

  dirty ranges

   You dirty, _dirty_ ranges.

   Dirk van Deun came across some interesting behaviour when he modified

 >> range = "a".."z"
 >> range.min[0] = "b"
 >> range.max[0] = "y"
 >> range

 # Editor note: All irb session outputs in this summary have been
 # and tweaked.
 # If you're confused by the [0], then observe that
 #   s = "hello"; s[0] = "j"; puts(s)
 #  results in "jello".
 # The examples could be rewritten to use foo.replace("xxx") instead of
 # foo[0] = "xxx".

   George O. said that the correct way to modify endpoints (if you
   is with Range#begin and Range#end.

   > #begin and #end are direct accessors to the endpoint objects,
   > #max is calculated, taking into account end-closedness. It should
not be
   > surprising, then, that #max and #end return different objects.

   Regarding the common feeling of Don't Do That (George: "Ranges
   are immutable, so changing their value indirectly like that is kinda
   against the grain"), Dirk van Deun said that it's more subtle than

 >> range = "a".."z"
 >> ary = range.to_a
 ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m",
 "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]
 >> ary[0][0] = "z"
 >> range

   There were a couple more posts pondering having range clone the

  Current Temperature (#68)

   Caleb T. came up with the week's Ruby Q..

 >  Write a Ruby program such that given a certain argument to the
program it

 >  the United States may be interested in temperature by ZIP code:
 >          $ ruby current_temp.rb 47201

 >  Other locales may want to use their own mailing codes, or city
 >          $ ruby current_temp.rb madrid
 >          The temperature in Madrid, Spain is 12 degrees C.

New Releases

  Second drop of RubyCLR bridge

   John L. released the second version of his RubyCLR bridge, which
   for Ruby integration with .NET 2.0 (other bridges out there only use
