mac-address in local network with (javaScript or PHP) -

-

so far know, cannot mac-address javascript or php - except ie users , if have activex.

but here 2 similar scenarios: , think these not duplicate questions...

1) can mac-address of every user (windows, android, apple, etc.) if website hosted locally , people access form via wifi? , if yes, can done php/javascript?

2) can mac-address of every user (windows, android, apple, etc.) if want track users 1 network, site hosted on linux server somewhere else? , if yes, can done php/javascript?

• in case need know why want this: online draw @ night club , track mac-addresses, can sign once every device.

can mac-address of every user (windows, android, apple, etc.) if want track users 1 network, site hosted on linux server somewhere else? , if yes, can done php/javascript?

this not possible.

can mac-address of every user (windows, android, apple, etc.) if website hosted locally , people access form via wifi? , if yes, can done php/javascript?

if the web clients on same subnet server read mappings arp table. on linux open text file /proc/net/arp using php script , lookup mac address using provided $_server['remote_addr'].

in case need know why want this: online draw @ night club , track mac-addresses, can sign once every device.

on local network, gain no security filtering on mac addresses instead of ip addresses. host's mac address trivial change on platforms.

python - Healpy: From Data to Healpix map -

Image
i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
