javascript - Adding a counter ID to a setInterval loop -

-

i'm working 3 functions:

  • startbubblemachine() starts process of making bubbles
  • makebubble() makes bubble bubbleid identify it. appends div.
  • killbubble() removes bubble

the timings creation of bubbles randomised using function randomint generates random int within range.

i'm struggling incrementing of bubbleid, needed create new bubble , ensure correct bubble destroyed. cannot work out @ stage increment. 

function startbubblemachine(){         console.log('starting bubble machine');         var bubbleid = 1;         setinterval(makebubble(bubbleid), randomint(6000, 1000));     }

this function pretty simple. initialises bubbleidand sets interval between 1s , 6s call makebubble(), passing bubbleid

this stuck

function makebubble(bubbleid){         console.log('making bubble number '+bubbleid);         $('.wrapper').append('<div class="db-bubble db-bubble-'+bubbleid+'></div>');         killbubble(bubbleid); // kill bubble current id         bubbleid++; // increment current id     }

the bubble made, killbubble() function called immediately. passes bubbleid ensure correct bubble murdered.

and increments bubbleid ready next bubble creation. but bit wrong, i'm sure.

finally, killbubble() has received bubbleid must murder. waits 2s, removes. 

function killbubble(bubbleid){         settimeout(function(){             // murder time             $(".db-bubble-"+bubbleid).remove();         }, 2000);         // kills bubble     }

my issue the process runs once. bubble 1 created, bubble 1 removed. bubble 2 never gets created.

jsfiddle

as using setinterval, bubbleid being passed value (only objects passed reference) makebubble funnction. use different name global counter parameter name in makebubble function.

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 .
