Negative overhead abstraction
Ariana
Ohhhhh
Ariana
Wow i didn’t know that
qsort whyyy
Ludovic 'Archivist'
I think Linux often have dedicated sorting algorithms per type to leverage that
Ludovic 'Archivist'
Because Cr. Torvalds likes his code duplication
Ludovic 'Archivist'
Hopefully, a kernel doesn't sort much stuff
Ludovic 'Archivist'
Which reminds me I have to find out a good way to do async on openbsd
Ariana
tbh im just more comfortable with C cuz i use too much assembly though C++ does seem a lot easier&better

Well, some test showed me that sometimes, assembly was strangely slower than C++
Ludovic 'Archivist'
Since then I do mostly C++
Ariana
Cuz optimizations is lit
Ariana
Compiler can optimise an insane amount
Ludovic 'Archivist'
That is because you may have some assembly instructions you may never think of using
Ariana
Also that
Ludovic 'Archivist'
My test case was the memcpy of glibc
Ariana
And also out of order computing
Ludovic 'Archivist'
Which is implemented as a sse2 memory copy
Ariana
In assembly human would do like
mov ax, 0
mov bx, 1
mov cx, 0
while its faster cuz outoforder to
xor ax,ax
mov bx,1
xor cx,cx

Also, by doing C++ (or C for that matter) I can use gcc's -march=native on my servers
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )
Ariana
how i that difficult?
Ariana
as in like what difficulties do you face
Ariana
Also, by doing C++ (or C for that matter) I can use gcc's -march=native on my servers
+c++ code is usually a lot neater
Ludovic 'Archivist'
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )
Ludovic 'Archivist'
Ludovic 'Archivist'
Will be a pain tho
Ariana
doable in a few mins tho
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )
But i not get this tree
Ludovic 'Archivist'
So much ifs
Ludovic 'Archivist'
But i not get this tree
fork, if you get 0 you are P, else you are 1.
if you are P, fork, if you get 0, you are P, else, you are 2
if you are P, fork, if you get 0,you are P, else you are 3
if you are 1, fork, if you get 0 you are 1, if you get 1 you are 4
Ludovic 'Archivist'
Go on until you have your whole graph
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )
Ludovic 'Archivist'
It is P for parent
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )
Yes
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )
Okay, i'm going try again
Ludovic 'Archivist'
Ludovic 'Archivist'
Go on to make the whole graph
Ludovic 'Archivist'
Just walk the graph left to right
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )
Just walk the graph left to right
It's like that the process create
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )
Left to right
Ludovic 'Archivist'
It's like that the process create
Organisation is key, do things one step at a time
Ludovic 'Archivist'
If you want help, you can try to pm me but my internet is scarce at the moment, will be better in a few hours
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )
Okay
Ludovic 'Archivist'
Also, I am a native French speaker if you have doubts on your english
#define CLEAR_BUFFER while ( getchar ( ) != ’ \n ’ )

A naitve march sounds like something hitler would do

show me your code

pm me the link

i haven't just deleted it. Clion don't suggest me class-members in code complete
BinaryByter
maybe its confused

Hello guys

How do I start building projects in c++
BinaryByter
Like you start building a house
BinaryByter
start with one line of code
BinaryByter
then add another one
BinaryByter
and one more
BinaryByter
and after you do that a few (or many) thousand times you are done
Anonymous
But I didn't get an idea of what to make and how to
BinaryByter
But I didn't get an idea of what to make and how to
if you don't know what to build, don't build anything
BinaryByter
If you want or need to build something, start with finding ideas
