I know I abuse these gifs but goddammit the idea of someone legit freaking out over a wrinkle underneath their eyebrow has made me lose it so hard that a worded reaction isn't enough

People typically say that IQ isn't a measure of intelligence because black people do so poorly on IQ tests. It's liberal propaganda.
Indeed, with the whole Mrz "Fail Hack, Dog sucked him off" fest that's been going on, we forgot about ole Peppers for awhile.
I'm still working on implementing a timing attack, it's more complicated than I originally thought but I will stick with it. Primarily it is complicated because so many things are getting in the way of accurate/precise timing measurements. I found an academic paper that discusses the implementation of accurate enough clocks to do this sort of attack though, and now I'm making frequent reference to it in furtherance of implementing my own, which will help a lot. It's already helped, because at first I was using a microtime function to get microseconds elapsed, but then I started reading this paper and learned that I should be counting CPU cycles with assembly instead, and then I found out how to do that.
//Using this for time as it is more accurate than the clock function I was using before
//as I learned in Opportunities and Limits of Remote Timing Attacks SCOTT A. CROSBY, DAN S. WALLACH and //RUDOLF H. RIEDI Rice University
__inline__ unsigned long long getCpuCycle(void)
{
unsigned long long int x;
__asm__ volatile (".byte 0x0f, 0x31" : "=A" (x));
return x;
}
I plan to stick it through though. So far I can't even predict an unknown string in a C program itself though, I need to get around some problems I'm running into, mainly interference in timing measurements from optimizations and cache in particular (cache makes earlier timing measurements more latent than subsequent ones). So far in a C program itself, with no jitter from the network or anything, this is my best timing differential attempt
guess for ""qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq" is "qqqqqqqqqqqqqqqqqqqqqqqbdrtdivx"
Once I get it accurately guessing the string in the C program itself I will work on increasing the precision by following this paper which explains the best way to go about it, I know I will need to disable cache and various other things that are introducing noise. Then I will add networking code to it and have it spoof cookies. It's turned out to be significantly more of a challenge than I thought it would be at first, but I'm confident I can do it, particularly since I started reading that paper that discusses the topic.

why are you running away you faggot
also you can't computer for shit
This is definitely taking me to a lower level than I've gone before, for example it required assembly to get the most precise timer measurements, and it's likely going to require assembly again + writing a kernel module to be able to disable cache. In the past I've not gone lower level than C, and didn't need to directly interact with more than RAM.
Actually I corrected my first post on this topic, I said I was using a microtime function, but I was actually using a nanotime function, but now I'm counting CPU cycles with assembly, which according to the paper I'm reading is the most precise way to measure time.

And you call yourself a chronophile.
Yeah I really screwed the pooch on that one.
Do you ever get sleep in your mom's basement?Yeah I really screwed the pooch on that one.
when u hackin the forums when should we be scurred. you have a low iq. is it tru u can't hack the forums bc your a dipshit?
Well I'm still developing the timing measurement code and everything, I admit it's more complicated than I originally thought it would be, but I'm sure I can do it eventually. I'm not sure if it will actually work against the forum, but theoretically I believe it should, though in any case I'm just doing this for fun and practice and such. One of the big problems I'm running into right now is cache distorting the timing measurements, and it looks like this will require me to write a kernel module in assembly to set a value in a register of the CPU to disable to cache. I also need to finish reading this paper, but as I mentioned it already has assisted me, as now rather than using a nanotime function I'm counting CPU cycles.
we need to have odds for each mrz visit.
what will his reply be?

3 should probably actually be drugs. My three favorite topics are drugs, JBs, and security.
