javascript - Resizing and compressing AJAX images in Node/AngularJS application -


i'm building app in angularjs, built on node/expressjs. have list of images hosted externally (and have no access them compress them @ source).

the issue is, these images quite large - ~200kb 600x600 image. don't want serve such large files users, on mobile data caps , whatnot.

is there service (or node module) allow middleman-style way of compressing images angularjs serves user? google pagespeed service (a surprising number of people haven't heard of this, check out, it's awesome) absolutely perfect, except doesn't work ajax images/angularjs.

you have services http://kraken.io/ - matter of hooking url pattern api call optimized image. problem such services aren't scalable (at least cheaply), since using third party bandwidth , processing power.

i advice caching files somehow, on side of things, though. or other way around - hook optimizing changes image list, , serve optimized files end.

doing angular doing each user's computer: limit of 50 files/day lasting (apparently) 1 hour on server, you'll run out of api calls.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...
