Hi,

Any good read or watch on how specifically the cpu retrieves data? Stack or heap and why buffer overflows *can* occur.

Hi,

look for the px8s2 but can be a month of saving up compared to pi8, what do we pick and why? purely on sound, not really interested in wear and other points

Hi,

I'm writing an app but kernel space restricts sys calls able to make but don't want stall time when flushing for a new security level, so is there a way to run a userspace app forced on the vlsi level to not switch. a usual 50-300 cycle penalty per switch is expensive when polling network and manipulating it in userspace, rinse and repeat?

Hi,

I have a conf file with reference of array names, is there a way for c to read conf file at runtime and find the arrays when stripped?

Hi,

If a cpu runs a program in userspace contrary to kernel space how much of execution time is penalized on context switching and cpu modes? there are two forces: cpu mode itself bit vector being flipped (eg. el0 - el3) and then the kernel switching.

nothing specific, just wet finger in air

Hi,

I wanted to ask how psychologically it will benefit or hurt you if you followed Jesus from the bible:

- don't steal

- dont hold grudges/vengence etc etc

Is there any benefit to it or just a lot of empty words from 200 years ago, if we subtract social disposability in a modern world, all having zero sum thinking which is what this in the end elliminates.

Hi,

How does bound checking and such work on a lower level?

Why is snprintf needed when a normal say normal signed ints don't need bound checking?

Today i got a reality check on stack is also not bound checked, how does it actually work, heap or stack?

Any books, videos and other material specifically on the asm level of it all the compilers story on it?

Hi,

I recently had an issue with clang complaining and giving an error when made a char array but when added a pointer (asterics) to it at the start the issue went away?

like this, with the second version of the char array won for the compiler.

char id[] = {"a", "baah", "raah"};
char *id[] = {"a", "baah", "raah"};
[...]
strcat(buffer, id[1]);
[...]

Hi,

To say the least my high school grades are....

If you have a good public portfolio could you get a job in HFT or is that dream closed permanently then?

Hi,

code:

\begin{tikzpicture}
    \draw -- (0,0)     
        -- (-6, 0)
        (-6,4)
        -- (0,4)
        (0,0)
        -- (4,2)
        -- (0,4);
        %-- cycle;
    \draw (-6,2) ellipse (1cm and 2cm)[rotate=90];
    \draw (0,2) ellipse (1cm and 2cm)[rotate=90];
    \end{tikzpicture}

Any survival tips?

hi,

how to combine strings and int with say two vars like:

strings1 = "monkeys"

int1 = "420"

combinedtoastring = "monkeys420"

Hi,

I had this question about what would happen if we say initiated a int at 17 bits, how will the cpu react? 17 bits flows from memory, now what
