00:47 <JesseChavezGitte> Hi @headius

00:54 <JesseChavezGitte> the encoding of the `w` variable are different in CRuby and JRuby, is there any reason for that ?

03:12 <headius[m]> Jesse Chavez (Gitter) hmm you should open an issue for that

03:12 <headius[m]> Could be something wrong with how irb gets input. Does it work properly as a script?

12:37 <aqd> how does jruby handle string internally, since java string is immutable/shared and ruby string is not? copy-on-write? but is there no method to reference a part of string (not copy like slice)?

12:38 <aqd> or it's just bytes internally and conversion happens every time from jruby to java and vice versa?

13:17 <kares[m]> aqd: second option is correct

13:17 <kares[m]> org.jruby.RubyString has a ByteList container (stores a byte[])

13:18 <kares[m]> but some ruby strings might end up being shared under the hood e.g. if you take a sub-string

13:19 <aqd> OH! is there an optimization/performance guide for jruby apps, things to avoid etc?

13:33 <headius[m]> There's a few good articles on the wiki for sure

13:33 <headius[m]> Could be better

15:33 <aqd> thanks! :)
