how pass array of bytes c# windows application sql server via stored procedure? code in sql :

        insert pers_usermachine (userid,nboftemplates,fingerprint1,fingerprint2,fingerchecksum1,fingerchecksum2)          values(             @userid,                         @nboftemplates,             convert(varbinary(max),@fingerprint1),             convert(varbinary(max),@fingerprint2),             @fingerchecksum1,             @fingerchecksum2                 )

and code in c#:

    public int saveuser(int id, string userid, int nboftemplates, byte [] fingerprint1, byte [] fingerprint2, int32 fingerchecksum1, int32 fingerchecksum2)     {         try         {             hybriddictionary paramsdictionary = new hybriddictionary();              paramsdictionary.add("@id", id);             paramsdictionary.add("@userid", userid);             paramsdictionary.add("@nboftemplates", nboftemplates);             paramsdictionary.add("@fingerprint1", fingerprint1);             paramsdictionary.add("@fingerprint2", fingerprint2);             paramsdictionary.add("@fingerchecksum1", fingerchecksum1);             paramsdictionary.add("@fingerchecksum2", fingerchecksum2);              dabase da = new dabase();             return int.parse(da.getscalar("punchmachinesaveuser", paramsdictionary).tostring());         }         catch (exception ex)         {             return -1;         }     }

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 .
