invalid_nameon Reverse engineering the Intel FSP: A Primer

because the compiler knows that the structure is located exactly 0x1AB bytes before the current function

This should be 0xF bytes before the current function, shouldn't it? I liked it.

invalid_nameon Saying Goodbye to Firebug

I expected a similar article when it was time to say goodbye to Internet Explorer as well.

invalid_nameon Benchmarking shared memory vs message passing on OS X

Yes, I got what you meant, and I know that some parts, especially those which cover measuring, should perhaps be investigated deeper. I'll outline the objectives better next time.

invalid_nameon Benchmarking shared memory vs message passing on OS X

What kind of work would it need sorry? Anyway I can understand this may not seem to be real benchmarking, while writing it eventually became almost an excuse, the very original purpose was to kinda verify my Prof's thesis, whether was really right or not. My intention was not even about to utterly speak about benchmarking nor shared memory (which I both tried to cover though).

invalid_nameon Benchmarking shared memory vs message passing on OS X

Wanted to just note down the numbers I got by timing, as then I said, I wanted to remark that was interesting how they are being used complementarily and had fun to implement them.

invalid_nameon Benchmarking shared memory vs message passing on OS X

I haven't even thought about graphs, I just called 'benchmark' the output of time(1).

Indeed I'm not merely speaking about shared memory, you can find anything anywhere about it. If you had really taken the time to read it, you would have just figured it out.

invalid_nameon Dreaming in Reverse Engineering

Mind asking a few things? What's the purpose of this line

  void *call_addr = (void *)CHECKSUM_CALL_ADDR;

to then casting the rvalue to a double void pointer here:

  void **target = (void **)CHECKSUM_CALL_ADDR;

(why not just void*) ? Also, even though mprotect() succeeds, I got a segfault.

invalid_nameon Basic Mach-O binary parser

Surely I'm gonna look on it :)

Yeah, problem is I messed up with links.
