i work on app send image android nodejs via socket io , got error when send data has size 700,00 kb in node js , don't know how can me work better ??? java code

file myfile = new file (selectedimagepath);             int ficher = (int) myfile.length();             system.out.println(""+size(ficher));             int file_size = integer.parseint(string.valueof(myfile.length()/1024));             system.out.println(""+file_size);             size(ficher);                 fileinputstream imageinfile = null;                 try {                     imageinfile = new fileinputstream(myfile);                 } catch (filenotfoundexception e) {                     // todo auto-generated catch block                     e.printstacktrace();                 }                   byte imagedata[] = new byte[(int) myfile.length()];                 try {                     imageinfile.read(imagedata);                 } catch (ioexception e) {                     // todo auto-generated catch block                     e.printstacktrace();                 }                 // convert base64;                 string imagedatastring = base64.encodetostring(imagedata, select_picture);             socket.emit("img", imagedatastring, "mak", "mak");

and javascript code (node js) here

socket.on('img', function(msg, usr, username){ console.log(' message : '+username+' \n message : '+msg+"\n : "+usr) console.log(usernames[usr]) console.log(usernames) io.sockets.socket(usernames[usr]).emit('event', msg, username);        fs.writefile(username+ "- -"+usr+'.png', msg, "base64", function(err){if(err){console.log(err)}})

});

this error got

aaal9woagfzc2v0cy9z\nzxr0aw5nc2nyzwvulnbuz1blbqyaaaaamqczamgnaacf/w4aaaa\n","243 810840505","apk","23:10"]} debug - emitting heartbeat client ig4qpjbtaegr20jos6ia assertion failed: end <= source_len, file src\smalloc.cc, line 280 c:\xampp\htdocs\socketio_android-master\socketio_android-master>

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
