Reverse a program, found that the program was setuid (0), Setgid (0) thus causing the program to run in root mode (specifically can be searched in iosre), so I would like to take this instruction to nop off.I looked up some methods on the Internet, such as:1, xx A0 E1 NOPI tried the next, in 32 bits, that ARM7 seems to be MOV r0 r0 (two weeks ago tried, remember not very clear.) Well, this also works. But under 64 bits, it becomes garbled, and Ida is all changed.2, with

Problem Description
Background
Professor Hopper is researching the sexual behavior of a rare species of bugs. He assumes this they feature two different genders and that they only interact with bugs of the opposite. In he experiment, individual bugs and their interactions were easy to identify, because numbers-were on printed BAC Ks.

Given A list of bugs interactions, dec
The space used for blog sites is usually very small. If there are too many local images, the space may be used up all of a sudden. Many bloggers have begun to favor external album albums, this saves space. I heard that external images have an impact on seo, but they are not well indexed locally. Here I think of a solution to this problem: disguise the link address of external images as a cost-effective image link, in this way, the search engine considers this image as a local image and solves th
