android - Countdown timer not working properly -

-

i trying use timer...when call countdowntimer.start()

i can see in debugger timeleft variable updated value=120000 want timer doesn't execute ontick method. jumps straight onfinish. if give timeleft literal works. 

    volatile long timeleft=0;     countdowntimer countdowntimer=new countdowntimer( timeleft,1000) {     @override     public void ontick(long timeleft) {             textview timeview= (textview)findviewbyid(r.id.timer);     long longtime=(timeleft / 1000);     integer inttime=(int)longtime;// convert long int     timeview.settext(string.valueof(inttime));}      @override     public void onfinish() {correctdialog("sorry,time up!!");}};}       (timeleft not fixed)

here first parameter in countdowntimer() constructor millisinfuture . giving value 0. finish whenever start timer. give value how time want execute times 10000 or 20000 etc...

so initialize timeleft

volatile long timeleft=10000;

check documentation countdowntimer

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 .
