javascript - Dynamically injecting code in Twitter Bootstrap carousel -


so, i've built responsive site twitter bootstrap. problem i've done using visible-phone, visible-tablet, , visible-desktop. means when views source code, have whole sections included twice or 3 times, in order around problems differences in span amounts, or, instance, because carousel on tablet should have 2 items, while on desktop should have 4.

i'm wondering if i'm doing right. should injecting (or adding? not sure of right name) code dom dynamically using javascript, based on screen size? or should editing around custom, simple .php files based on screen size? don't know, , can't find answer practice anywhere. i've tried looking @ sites this, never find javascript script adds stuff in situation. given, i'm not sure i'd looking for.

any pointers?

i avoid using script dynamically add content; fellow developer makes less intuitive (in opinion) , aim produce intuitive code chap after me.

if requirements state carousel should have 4 items on desktop , 2 on mobile, think solution valid.

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).
