java - Dictionary: hard-coded vs. external file -


i have java application started , stopped multiple times per second on hundreds of millions of items (called external script).

input: string key output: int value

the purpose of application key in never ever ever changing map (~30k keys) , return value. easy.

question: more efficient when used multiple times per second:

  1. hard-coded dictionary in map
  2. read external file bufferedreader
  3. ...amaze me other ideas

i know hard-coding evil sometimes, need evil efficient :-)

read in dictionary file. store in map. set java application service runs continuously (since said gets called many times per second). map cached in ram.

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).
