linux - Find fails to find files below 1M but works fine with 'k' units -

-

i have created file named 1.txt , 9kb in size:

stat 1.txt   file: `1.txt'   size: 9322            blocks: 24         io block: 4096   regular file access: (0600/-rw-------)  uid: (    0/    root)   gid: (    0/    root) access: 2015-06-26 10:12:47.000000000 +0100 modify: 2015-06-26 10:12:47.000000000 +0100 change: 2015-06-26 10:12:47.000000000 +0100

when run find command option -size -100k k units, file found:

#find . -type f -size -100k #./1.txt

when use m units , -size -10m file still found:

#find . -type f -size -10m #./1.txt

but when try find files less 1m in size, find doesnt find file:

#find . -type f -size -1m #

and yes, version of find (find (gnu findutils) 4.4.0) supports m unit.

i believe because units represented integers, , "less 1" 0, searches files 0megs in size.

counter intuitive sure, retained backward compatibility distant past.

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 .
