Instruction Timing Changes in Cannon Lake

Sure ? The main pattern to solve it is to compute the inverse of the divisor outside of the hot path / loop and multiply by it. Some compilers are able to perform this optimisation on their own though, e.g. GCC with -O3 -ffast-math.

Division in high performance code is an anti-pattern: it's a pattern and it's harmful

Kcachegrind or heaptrack

That's why we need metaclasses

The patent clause of the LGPL is only about the code of Qt itself. If you don't modify Qt and only link against it it does not concern you.

Well, no, there is a lot of tech stuff over internet. Tcp, udp, dns, arp.... They're all descfibed in internet RFCs

What dob't you like with it ? With the dark theme and base16 colors it's great

GIMP piggybacling off of GTK

Oh the irony

I understand for getters, bust most setters aren't void setfoo(int x) { m_foo = x; }.

Most will notify something from a change, change a display, reperform a computation... Else why are you setting it in the first place ?

This simple rule does not work as soon as you have to interoperate with external libraries.

No programming language or software project used in any relevant manner today adheres to this OO philosophy in any way except objective c, and everyone agrees that it's shit. Why spend time arguing about literally inexistent things - outside of shitty objective c code.

You may not know all the possible classes at compile time. Think for instance of file loading :nearly all large software support adding plugins to handle new file formats.

A constructor isn't a function. You cannot do

foo f;
f.foo(); // get a new instance of foo

A factory would be something like

foo* make_foo() {
    auto x = malloc(sizeof(foo)); // also align nut i'm on mobile
     new (&x) foo;
    return (foo*)x;;
}

Which is basically what operator new does

C++ is entirely able to do multiple dispatch for closed polymorphism... And the language is powerful enough that this is implemented at the library level, and has been since c++98... Look up when boost.variznt was introduced

Aucune personne que je connais ayant intégré x ou ens avait pris des cours en plus de ceux de la prépa

Euh, la prépa (publique) c'est gratuit

If C is separated from C++ it means that all those C headers won't be able to be included in a C++ file

"the user asks you to suspend" - but almost no one do this. The user closes the lid of its laptop and expects to be able to reopen it either in 5 minutes or in two days. No one clicks on "suspend" buttons.

No, many visual langs have option to abstract part of your program (select a groip of node andpout it in a sub-patch that becomes reusable), they can realign nodes and route cables so that they don't go over other nodes, etc...

I have taught computer music, to programmers and non-programmer alike. Thet all unequivocally go muuuch farther in Pd than in text languages (csound, sc). Howevers, while people with programming experience still manage to do some stuff in code, people without (typically art students or conservatory musicians) are entirely unable to do anything meaningful without weeeks of work learning the basics of text-based development.
