precision - Fast, arbitrary floating points in Python -


so i'm trying compute mandelbrot set @ large magnifications, , have run bit of brick wall.

using pythons own float paired jit gave me plenty of speed.

but after having switched on use decimal instead, function started returning 0 fields. turning off numba's jit solved problem, performance of software has plummetted unusable(~30 seconds 100 iterations on 64x64 field floating point precision of 6).

my code:

def mandelbrot_point(creal, cimag, maxiter):     real=creal     imag=cimag     n in range(maxiter):         real2=real*real         imag2=imag*imag         if real2+imag2>4.0:             return n         imag=2*real*imag+cimag         real=real2-imag2+creal     return 0

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
