java - JSONObject inside JSONArray -

-

i'm trying put jsonobject inside jsonarray in java. here 2 objects:

jsonarray:

[{     "url": null,     "flag": "0",     "read": "0",     "time": 2000,     "exp": null,     "population": 10 }]

jsonobject:

{ "events": [     {         "color": "green",         "event": "restart"     },     {         "color": "black",         "event": "shutdown"     },     {         "color": "white",         "event": "read"     }        ] }

expected result:

[ {     "url": null,     "flag": "0",     "read": "0",     "time": 2000,     "exp": null,     "population": 10,     "events": [         {             "color": "green",             "event": "restart"         },         {             "color": "black",             "event": "shutdown"         },         {             "color": "white",             "event": "read"         }     ] } ]

i tried use code, result not ok:

jsonarray.put(jsonobject);

unexpected result:

[ {     "url": null,     "flag": "0",     "read": "0",     "time": 2000,     "exp": null,     "population": 10 }, {     "events": [         {             "color": "green",             "event": "restart"         },         {             "color": "black",             "event": "shutdown"         },         {             "color": "white",             "event": "read"         }     ] } ]

the "events" key-value inside unique element in jsonarray, not element.

the jsonarray contains 1 jsonobject. when jsonarray.put(jsonobject); adding jsonarray, not jsonobject in jsonarray.

this add jsonobject first jsonobject in jsonarray

jsonarray.getjsonobject(0).put("events",jsonobject.get("events"));

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 .
