javascript - Solving API Performance Issues with Cross Domain Ajax -


i'm in process of building out infrastructure support gaming platform intend scale out hundreds of thousands of users. since in entertainment / gaming industry, expecting heavy load each user session, therefore, performance of upmost importance.

we trying parallelize of architecture possible, meaning api, databases, , applications run off of different servers can horizontally scaled. 1 of applications web app, , we're having trouble due specific scenario involving same origin policy on legacy browsers.

this application running in web browser need speedy access models available through centralized api. while great our dedicated mobile clients, browsers unfortunately need cors support interface directly our api. problematic because of http verbs not supported on browsers (put / delete). our known workarounds are, rewrite api create more abstraction (we believe not best practice , increase development time , potentially performance) , work post using jsonp or create proxy (which add 2 leg trip , double latency performance).

bottom line is, have boiled question down to... these 2 options, or there else aren't considering, , if so, of these solutions better suited gaming platform.

another option consider jsonp. wrapping json response enable loaded script tag, can avoid problems same origin policy.

i can't speak performance issues of specific application without knowing app in detail. think see similar performance on server jsonp, since major difference on other methods concantenating string.

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...
