ruby - jRuby and Rubinius support parallel computing, but what about gems that don't support this? -


what i'm trying understand is, practically speaking, how benefit parallel computing support in jruby / rubinius? lot of ruby libraries keep track of global internal state. there way deal these libraries, or become unusable if decide parallelize ruby script? maybe rubinius automatically puts mutex in front of usage of unsafe libraries?

whenever want use jruby or rubinius, you'll forced use gems compatible.
many gems has been implemented using c extensions , can not use them along jruby e.g.
regarding others, states thread safety status.

so choosing jruby or rubinius narrow down options regarding gems. huge opportunity exposed, you'd able use many mature java libraries(in jruby case).

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
