Optimize write of large file
383059 [yoann6@gm il] I have data to process and to write into files progressively. The data
+ 383062 [mbj@se ni .n] Ruby and the glibc the kernel etc are doing buffering already.
+ 383071 [jeremy@bo p.] As mentioned, the file writes are already being buffered by lower

Git configuration file: .gitconfig
383075 [kmandpjlynch] Good morning,
+ 383078 [hassan.schro] It's optional; but if you want one, create it.
| 383083 [kmandpjlynch] Thank you Hassan...

| | 383106 [kmandpjlynch] ...sorry, this was a topic in the AWDWR book - I should of posted my

|   383118 [kmandpjlynch] ...ok, will do - sorry...
|   383122 [cmdjackryan@] No need to apologize all the time. :)
+ 383095 [ibc@al ax ne] And the question about Ruby is...?
  383104 [kmandpjlynch] ...sorry, I thought Git was the preferred version control manager of Rails

Shell pipeline in Ruby?
383093 [hramrach@ce ] how do you write an equivalent of
+ 383101 [jos@ca no k.] Have you checked out Open3.pipeline?
| 383126 [hramrach@ce ] I have checked all the stuff I could find once but did not find a solution.
| 383132 [stu@ru yp og] There is also popen4 which I believe also gives you the pid with std -
| 383134 [hramrach@ce ] It provides stderr but not the pipeline which cannot be constructed in

+ 383181 [rogerpack200] Enjoy.
| + 383190 [hramrach@ce ] Unfortunately, this does not work.
| | 383204 [rogerpack200] Try it now, fixed the bug.
| + 383206 [rogerpack200] Unfortunately it appears the wiki formatting is mangled in firefox, but
|   383225 [hramrach@ce ] Changing the last line to
+ 383192 [shortcutter@] $ ri Open3.pipeline_r Open3.pipeline_start
| 383203 [hramrach@ce ] Again, like in Open3.pipeline the :err argument used in the example is
| 383208 [shortcutter@] Each cmd is a string or an array. If it is an array, the elements are passed
| 383219 [hramrach@ce ] It's not quite clear that Process.spawn description also applies to
+ 383216 [hramrach@ce ] OK, thanks for all the replies.
| 383251 [b.candler@po] Since you are doing this on a real operating system, there's no need to

Mechanize retrieve headers
383096 [rob_gar_esp@] I'm using mechanize for web inspection, when I get a URL I get a refresh
383165 [bbxx789_05ss] The Mechanize docs follow the ruby tradition: they suck.  So I would

Jruby -v failing with possible Java version issue
383098 [ruby.student] I installed jruby 1.6.1, as fully described below.

  383108 [ruby.student] root@myserver # which java
  383115 [matt@ha ps a] 1.4.2 won't work.  You need java 1.6.  FWiW, Java 1.4 was sunsetted a
  383125 [ruby.student] But I have 1.6, I installed it.
  + 383129 [cmdjackryan@] Yes, you can. Just make sure to install OpenJRE/OpenJDK to its own
  + 383136 [matt@ha ps a] That may be the case, however, when you ran java -version, it says 1.4.2
    383221 [ruby.student] OK gents, I installed Java 1.6 and pointed to it via the JAVA_HOME
    383264 [headius@he d] Just saw this thread today...

Email Parsing
383140 [piratej74@li] How would I only pull links from the email's body and not the full
+ 383143 [b.candler@po] "Links" to me implies that this is an HTML email. In that case, just
+ 383152 [piratej74@li] That worked out well thank you very much.
+ 383159 [ryand-ruby@z] BTW... we're discussing stabbing you in the 'indenting "end"' thread. :)
  + 383167 [cmdjackryan@] def stab
  + 383174 [code@ap th o] I, for one, would really rather not be stabbed in the indenting end.

| | 383148 [code@ap th o] Oh, good -- I'm not the only one.
| | 383155 [shortcutter@] LOL
| | 383157 [code@ap th o] Maybe I'm just lucky.
| + 383149 [sduncan@we a] I find this indenting gets best results, and more groupies.
|   383154 [code@ap th o] That's perverse.
+ 383150 [johnf@bi sb ] I've never seen this even once except when it was a mistake, but maybe

Re: rubygems-update 1.8.2 Released
383169 [rogerpack200] As an interesting note,
383193 [ryand-ruby@z] Unfortunately, that's a rails gem-hack issue... (I suspect).
383298 [rogerpack200] I've noticed that the "gem which" command seems to have changed.
383299 [ryand-ruby@z] 3006 % gem unpack ruby-prof
383396 [rogerpack200] Ok that makes sense, though causes a bit of confusion.

Any working translation framework available for Ruby

Counting how many times the same elements occurs in an array?
