URL polling as a simple streaming mechanism in Matlab (or in general) -


i stream images between 2 computers storing images on 1 computer , reading them on internet url on computer using matlabs imread function.

i doing creating stream of png images webcam on 1 of computers. connected network drive available through public webadress.

on other computer running loop such:

while 1  = imread('http://mywebaddress.blah/image.png');  imshow(i);  drawnow end

the problem works 3 or 4 frames , crashes matlab. doesnt throw exception, crashes.

im guessing because there synchronization error isnt being accounted in matlab's imread code url based images. guess if image half available when being streamed , stops being available because been overwritten on other side matlab hasnt accounted , bombs.

i need simple mechanism synchronization. second computer can read information. cannot send information. synchronization wont perfect id method result in absolutely minimal crashing... have ideas?

i think need solve problem @ server side. see how can have, say, 10 recent images named image00.png through image09.png. instead of overwriting image that's being served up, instead serve "currentimage.png" link points recent image. update link whenever new image created, , have 10x longer read image before gets overwritten. can create deeper 'buffer' depending on frequency updating images, , latency of reading.

if isn't clear let me know , can try elaborate.

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...
