php - How can I check a 0-confirmation Bitcoin transaction without having the private key in my wallet? -


i programming site accepts bitcoin payments, not want hold private keys on server. using so-called "lazy api" method create private keys , addresses ahead of time off-line, , customers send them, , want notified when transaction happens, fast possible, 0 confirmations.

i can't figure out how programmatically, unless add private key bitcoind's wallet, don't want security reasons. i'd prefer in php, i'll settle whatever.

on lazy api page, suggests using blockexplorer.com check confirmations.

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).
