ruby - Is iterating over a constant a best practice or not? -


in ruby script, i'm declaring constant outside of method:

syndications = %w(advanced syndication, boxee feed, player mrss, ipad mrss, iphone mrss, youtube)

and iterating in method like:

def some_method    syndications.each |syndication|       puts syndication    end end

is iterating on constant idea or not?

you aren't iterating on constant — iterating on array, happens referenced constant. constant kind of variable isn't meant reassigned. don't deal constant — deal object references.

so question becomes: ok iterate on array?

and obvious answer question is: yes.

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...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
