c# - Show binary code of external files/program -

-

one way or another, digital data stored in 0 , 1. that's principle of binary data, guess.

is there method or package can show binary code of file/single-exe-program of how being stored in 0/1 format??

i see like: - import certain, random file - convert it's 0/1 format - store the 1/0-data in txt (streamwriter/binarywriter)

if yes, available in .net language (pref: c#)?

essentially need break 2 steps:

  1. convert file bytes
  2. convert byte binary string

the first step easy:

var filebytes = file.readallbytes(somefilename);

the second step less straightforward, but still pretty easy:

var bytestring = string.concat(filebytes.select(x => convert.tostring(x, 2).padleft(8, '0')))

the idea here select each byte individually, converting each 1 binary string (pad left each 1 8 characters, since many bytes have leading zeroes), , concatenate of single string. (courtesy in part of @xanatos' comment below.)

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 .
