there issues in code. move following code onpostexecute method

de     = (textview) findviewbyid(r.id.dd);                     lt      = (textview) findviewbyid(r.id.ltd);                     le    = (textview) findviewbyid(r.id.lted);                     me = (textview) findviewbyid(r.id.mad);                     @      = (textview) findviewbyid(r.id.ad);                     lo    = (textview) findviewbyid(r.id.tvr);                      pe          = (textview) findviewbyid(r.id.pd);                               = (textview) findviewbyid(r.id.id);                     pe        = (textview) findviewbyid(r.id.pd);                     re             = (textview) findviewbyid(r.id.rd);                     tt      = (textview) findviewbyid(r.id.td);                      runonuithread(new runnable() {                           @override                         public void run()                          {                             de.settext(trnsdate);                             lt.settext(pledamt);                             le.settext(ltradate);                             me.settext(matdate);                             at.settext(stat);                             lo.settext(pledno);                              pe.settext(pi);                             it.settext(ir);                             pe.settext(ph);                             re.settext(rt);                             tt.settext(tt);                           }                     });

reason: don't use ui widgets in doinbackground method

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 .
