i quite new nginx, , seems confusing. have server setup perfectly, problem is, since server protected using http proxy; instead of logging real users ip's, it's logging proxy server ip. what tried doing setting $_server['remote_addr']; $_server['x-forwarded-for']; i'm getting undefined index error, i'm guessing have define x-forwarded-for in nginx? not aware how so, have simple setup, it's nginx php. nothing more, nothing less. i've searched on web, can't find information friendly understand. i have access source code, if helps. i've tried many solutions, no avail. the correct way of doing setting real_ip_header configuration in nginx. example trusted http proxy ip: set_real_ip_from 127.0.0.1/32; real_ip_header x-forwarded-for; this way, $_server['remote_addr'] correctly filled in php fastcgi. documentation link - nginx.org

i've been struggling understand best possible running time of this: for t = 1 n sum = 0 = 1 t sum = sum + x[i] i understand first loop go n times. it's inside loop struggle with. inside loop go n(n+1)/2 first time n(n+1)/2 -1 next time. i'm not sure how translate best running time. i use push in right direction if possible. thank you! in order visualize this, take approach of imagining area filled squares or volume filled dice in more complex cases. each square represents atomic step. steps of iteration of the outer loop put on same row. case, looks this: t=1 # t=2 ## t=3 ### t=4 #### t=5 ##### as can see, these form triangle, who's height n , who's width n. if count squares (n * (n + 1) / 2) have number of iterations of inner loop. multiplying , dropping irrelevant terms gives complexity θ(n*n).

i want create simple python script let's me create image file , place word dead-center on canvas. however, while can word align horizontally, can't center vertically. on macos btw. have tried far: import os pil import image, imagedraw, imagefont font_path = os.path.join(os.path.dirname(os.path.dirname(__file__)), 'fonts') font = imagefont.truetype(os.path.join(font_path, "verdana.ttf"), 80) w, h = (1200,200) msg = "hola" im = image.new("rgb",(w,h),(255,255,255)) draw = imagedraw.draw(im) w, h = draw.textsize(msg, font) draw.text(((w-w)/2,(h-h)/2), msg, font=font, fill="black") im.save("output_script.png", "png") i considered font in textsize calculation. word still appears 5-10% below middle. ideas? textsize seems return size of actual text , not of line. it's smaller ooo xxx ! i think should use 80 — size gave pil — height, although can't guarantee it's correct.
