|   354308 [b.candler po] Oh, and there is also IO.pipe, which is unidirectional under most Unix
|   354309 [gohegdeh com] I've tried pipes, but it seems to always think there's data to be read.
|   354311 [vikkous gmai] My recollection is that on windows, select only works on sockets. It

|     | | 354415 [gohegdeh com] # Required support, go to process dir
|     | | 354429 [b.candler po] But that message never appears in the output you showed - and this line

^ Rounding float in ruby via .round
354268 [shevegen lin] .round does not want arguments. Is there a reason why not?
354270 [pg thimian.c] Hmmm..

354284 [rupert peakl] I have this array...
+ 354286 [marnen marne] That array contains one entry, a Yahoo::GeoPlanet::Place object.
| 354290 [anoiaque gma] You should have an accessor , try  : geo_planet_object.woe_id .
