javascript - node js websock process -

i trying process data got in port. code :

var websocketserver = require('ws').server, wss = new websocketserver({ port: 5678 });  wss.on('connection', function connection(ws) {     ws.on('message', function incoming(message) {          function time_m() {             var my_month=new date()             var month_name=new array(12);             month_name[0]="jan"             month_name[1]="feb"             month_name[2]="mar"             month_name[3]="apr"             month_name[4]="may"             month_name[5]="jun"             month_name[6]="jul"             month_name[7]="aug"             month_name[8]="sep"             month_name[9]="oct"             month_name[10]="nov"             month_name[11]="dec"             return month_name[my_month.getmonth()];               }         function acc_array (n) {             var arr_acc = new array ("xaxis", "yaxis", "zaxis");             return arr_acc[n];         }         function sosjson() {              function formatdate(d) {                 return d.getdate() + '-' + (time_m()) + "-" + d.getfullyear() + " " + d.gethours() + ":" + d.getminutes() + ":" + d.getseconds() + ":" + d.getmilliseconds() +" ist";             }              var sosjsonobj = {};             var observations = [];             var record = [];             var output = [];             var version = "1.0.1";             var sensor = "mysensor";             var starttime;             var name;             var value;             sosjsonobj.version = version;             sosjsonobj.observations = observations;             observations[0] = {sensor, record};             var i;             var msg = [];             msg = message;             console.log("reading array value of messgae");             console.log(msg[0]);              (i = 0; < 3; i++) {                 //sleep(100);                 name = acc_array (i);                 value = msg;                 output.push({name, value});                 starttime = formatdate(new date());                 record.push({starttime, output});             }              return json.stringify(sosjsonobj);         }             console.log('received: %s', message);     });     sosjson();     ws.send('something'); });

but showed :

/home/root/node_modules/ws/websock_01.js:43             observations[0] = {sensor, record};                                      ^     syntaxerror: unexpected token ,         @ module._compile (module.js:439:25)         @ object.module._extensions..js (module.js:474:10)         @ module.load (module.js:356:32)         @ function.module._load (module.js:312:12)         @ function.module.runmain (module.js:497:10)         @ startup (node.js:119:16)         @ node.js:906:3

i not able find the issue having. node js not processing data. function calling guess not working properly. or else declaration may not correct.

the string observations[0] = {sensor, record}; not correct, if want object, should this: observations[0] = {sensor : sensor, record : record}; or array : observations[0] = [sensor, record]; in case better use object

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 .
