jvm - How to compress variables in Java using leading zero byte suppression? -

-

leading 0 byte suppression means leading 0 bytes of integer value removed , instead number of eliminated bytes stored. example: suppose have 32-bit integers, hexadecimal value 00000090 encoded binary value 01110010000, 011 means there 3 0 bytes in 00000090.

my question how implement leading 0 byte suppression in java? give me examples?

in example, suggest 0x00000090 encoded 11-bit number 0b01110010000. know, there no 11-bit data types in java, doing "the java way" impossible.

the way can think of achieve you're trying use single byte array store of data, implement 0 byte suppression algorithms on top of that. of course, remove entire point of java, object-oriented.

if you're trying implement sort of integerzerobytesuppression class, effort naught, because every object in java comes several bytes of overhead anyway, far outweighing few bits you'll save 0 byte suppression itself.

in end, if really need few bits of memory you'll save (doubtful, don't know you're working on), suggest either finding language little no overhead in object-oriented capabilities (e.g. c++) or language implements 0 byte suppression default (?).

python - No exponential form of the z-axis in matplotlib-3D-plots -

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 .
