"Dummy" IO object to push and pull data?
354265 [gohegdeh@co ] I'm relatively new to advanced Ruby programming, and I seem to be in
+ 354266 [ryand-ruby@z] ri StringIO
| 354273 [gohegdeh@co ] objectA = StringIO.new("")
| + 354276 [sophrinix@gm] Depending on your application, fakefs might be worth while.
| + 354291 [shortcutter@] If your scenario is such that for any particular thread you are always
| + 354303 [b.candler@po] Ah, then you want something with a real underlying O/S file descriptor.
|   354308 [b.candler@po] Oh, and there is also IO.pipe, which is unidirectional under most Unix
|   354309 [gohegdeh@co ] I've tried pipes, but it seems to always think there's data to be read.
|   354311 [vikkous@gm i] My recollection is that on windows, select only works on sockets. It
|   354352 [gohegdeh@co ] To make sure that I've been using it right, select is supposed to check
|   + 354353 [vikkous@gm i] It returns an _array_ of arrays of ready file handles.
|   + 354354 [tony@me io .] I'd again ask if you're trying to do I/O or thread synchronization here.  It
|     354358 [gohegdeh@co ] Well, it seems the problem is primarily occuring with Open3.popen3
|     + 354383 [b.candler@po] Sorry, I've read that several times and I still don't understand. Can
|     | 354402 [gohegdeh@co ] My apologies: I'll see if I can elaborate a bit...
|     | + 354403 [gohegdeh@co ] Hm, let me give an example of what this would output. The process that
|     | + 354404 [b.candler@po] Perhaps it would be helpful to distinguish symptoms from your assumed
|     | | 354408 [gohegdeh@co ] I've actually tried these myself; it doesn't get past the stdin.puts
|     | | 354415 [gohegdeh@co ] # Required support, go to process dir
|     | | 354429 [b.candler@po] But that message never appears in the output you showed - and this line

|     | | 354431 [vikkous@gm i] Except when I actually read the msdn link above, I see it only works
|     | + 354454 [shortcutter@] That can't normally be, because the thread runs independently of the

Rounding float in ruby via .round
354268 [shevegen@li ] .round does not want arguments. Is there a reason why not?
354270 [pg@th mi n. ] Hmmm..
