ruby on rails - difference between running rake command with and without bundle exec -


what major difference between running rake command , without bundle exec?

i have seen few posts stated when run command bundle exec run on scope of gems version defined in gem file. if case, should mandatory run rake command 'bundle exec' ??

bundle exec rake some:task runs rake task within context of bundle.

you didn't explicitly mention rails see you're post tagged rails contrived example of in action might following:

you have version 2.0 of fictitious whateva-whateva gem installed on system valid reason.

you decide want pull down old rails project somewhere check out , run bundle install within cloned project's root folder. command install of gems rails app requires , 1 of them happens verison 1.0 of fictitious whateva-whateva gem.

so current state this: old rails app has gem bundle includes older version of whateva-whateva , systemwide gems include newer version of whateva-whateva gem.

when run rake tasks associated rails app, version want loaded? older 1 of course.

in order can use bundle exec rake the:task , runs rake command within context of bundle -- older version of gem plus whatever other stuff specified in old rails app's gemfile.

so yeah after that, think it's safe best practice should prepend bundle exec honest i'm pretty lazy , unless see problems.

in other news, if use bundler's binstubs don't need add it. here's link setting up: http://robots.thoughtbot.com/post/15346721484/use-bundlers-binstubs

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
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
