ruby - Rails application notify changes in local embedded system -

-

i need display status of embedded system on webpage updates automatically.
idea use thread in infinite loop looking changes on system 

loop   old_status = status   status = board.request_status()   if old_status != status     # notify change connected browsers   end   sleep 1 end

and notify users faye in episode 260 of railscast.

i've tried using simple thread inside model , sidekiq, need run independent rails application yet still being able communicate it.

does have idea on how can it? i've been researching past week without success

useful information:

rails version

%> rails -v   rails 4.2.3

ruby version

%> ruby -v ruby 2.2.2p95 (2015-04-13 revision 50295)

uname -a

%> uname -a     linux server 4.0.8-2-arch #1 preempt tue jul 14 18:45:50 mdt 2015 armv6l gnu/linux

i'm pretty new rails.
in advance

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/...
