osx - Troubleshooting 404 received by python script -


i have python script pings 12 pages on someexamplesite.com every 3 minutes. it's been working couple months today started receiving 404 errors 6 of pages every time runs.

so tried going urls on pc script running on , load fine in chrome , safari. i've tried changing user agent string script using , didn't change anything. tried removing ['if-modified-since'] header didn't change anything.

why server sending script 404 these 6 pages on same computer can load them in chrome , safari fine? (i made sure hard refresh in chrome , safari , still loaded)

i'm using urllib2 make request.

there multiple reasons this, such server rejecting request based on missing headers, or throttling.

you try , record request header in chrome using http headers use python requests library adding browser headers in request. try either changing or removing headers see happening.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
