Sass compilation using Grunt and the role of ruby -

-

we use visual studio 2013 our development , need have .sass files compiled css (and same part of build/ci). exploring options grunt/gulp.

in following urls, there mention need ruby installed on machine in order have sass (monitor and) compilation using grunt:

in following urls, there no mention of ruby achieve same task:

what ruby, , how related (if so) sass compilation using grunt? can not achieve task without ruby? if so, advantages/disadvantages.

ruby programming language; sass written ruby. must have ruby in order install , use sass. away using sass without ruby if use http://libsass.org/ (a c implementation of sass). libsass should more performant beginner may want stick regular sass because setup easier.

those 2 links don't mention ruby because assume have sass setup. explaining how setup grunt.

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/...
