Rubicon Failure

34522 [Dave@Pr gm t] Which version of rubicon are you running? It looks like TestDir is

| 34527 [Dave@Pr gm t] I'm not sure - I just refreshed both the ruby 1.7 tree and the rubicon
| 34537 [ruby-lists@w] Did the same, but didn't help.

  34568 [Dave@Pr gm t] Full of hard-coded paths, but, for what it's worth... :)

Windows Installer Ruby 166-0 available
34517 [andy@to ls e] The first version of the MSVC version of the Ruby installer

| | + 34564 [bobx@li ux a] Great job Andy!

| + 34559 [ljohnson@re ] Both ;) The installer doesn't require Cygwin, and the Ruby it installs
+ 34596 [pcs3@ma lh s] Superb.  But do the installations really need to include an editor?
| + 34628 [Stephan.Kaem] Well it's not absolutely neccessary, but it's a nice to have...

dispatching and class references
34554 [probertm@no ] Thank you for everyone for helping me with my dispatch
34556 [paul@at es .] Returning by value is almost the same as returning a reference to a
34561 [probertm@no ] Now I -am- confused! :-)
34562 [paul@at es .] It looks like you've frozen your container but not the objects inside.
+ 34563 [probertm@no ] Got it!
+ 34575 [rokosm@kl ka] But objects inside are not frozen.
  34576 [paul@at es .] Sounds like something out of a bad movie :)
  34600 [pcs3@ma lh s] It does, but there's also an issue here about where does it end that all
  34607 [rokosm@kl ka] You can do this, if you set appropriates $SAFE level.
  34781 [paul@at es .] I think there is some use for such a method, but I'm not sure how it

  34598 [elanthis@aw ] I've only got two of the three, only one of which is still functional
  34603 [matz@ru y- a] I wanted to see the API, if you can't release the whole code.
  34604 [elanthis@aw ] The link to the code I provided has an API like the other two languages

  34583 [tobiasreif@p] No doubt. I didn't mean Win is $0; but when I buy some prebuilt

overriding operator 'or'
34571 [ptkwt@sh ll ] According to "Ruby in a Nutshell" pg 18, 'or' is a nonmethod operator

rdoc/xml questions
34597 [Dave@Pr gm t] I'm wondering about having rdoc generate xml output, and have a couple

| | | 34630 [tobiasreif@p] (the example is bogus, but that's probably what RDF would look like +/-)
| | + 34629 [tobiasreif@p] XMI may be verbose, UXF usable, and XTM cool.

| |   | 34640 [james@ru yx ] None. Never said there was. I came to my opinion after reviewing existing markup schemas.
| |   | 34642 [tobiasreif@p] This is going nowhere. So I misunderstood you, and you reviewed all

Using DBI with Mysql problem
34615 [beripome@ya ] Win 2000, Ruby Installer 1.66-0.
34622 [520079130762] The Mysql.rb file (MySQL DBD) is missing!
34663 [beripome@ya ] I thought so (duh). Installed and works great now. Thanks for the link
34686 [Dave@Pr gm t] Nope - probably just something got left out.

|   | 34774 [gehlker@fa t] In the context of the conversation, he clearly meant the latter.
|   | 34795 [cjack@cj ck ] My take is this is more due to the current development stage of RubyCocoa
|   | 34814 [gehlker@fa t] You could be right here. I'll have to play with some Ruby Tc apps and see if
|   + 34749 [benoit.cerri] Yes but both (recent jvm and clr) use advance generational collectors
+ 34654 [ysantoso@je ] Why? Depending on what you do and how you do it, GC can be much faster
