I found your post on SO Best way to follow a log and execute a command when some text appears in the log



You are at the very bottom of the post where you made it readable and that makes sense (to some degree) I get it as a concept...



I have a PHP form processor. It's integrated into a few hundred websites and multiple forms on websites. I have done a lot of user-friendly spam catching etc for these forms but as we all know it's painful.



How can I use the post above to say count the number of times a certain IP Address filled out a form. ie. this IP has filled out Xnum forms in X seconds, it's a robot, ban this IP via iptables and record this to a different log so we can expire them based on a date-time in that log. Sort of a general idea and I'm sure there are many solutions, but I don't have one. Any suggestions would be very much appreciated. - Thanks in Advance

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
