FUCK

OFF

>t. discord employee on unpaid internship

What the fuck makes you think I'm shilling for discord?
I'm saying FUCK OFF with any and all chat shit including discord, IRC, or whatever the fuck.
Just fucking post in this thread for fucks sake. Or better, fuck off and kill yourselves instead so we don't have to deal with you fucks in our thread.

There has never been any sort of official "chatroom" or anything for these threads, no matter if it's gaymur shit like discord or even IRC.
Fuck off and stop posting extra stupid shit in the OP.

>contribute to the FOSS project meme

I agree with this guy.
any doings on the side kills these threads because ego's in chat.

>replying no normalfags
just stop you dweebs.

>Just ignore them and let them shit up the thread and OP
How about you fuck off and kill yourself alongside them

IRC and discordfags are the worst

It's such a shame. I like atom on an interface level but everything else about it sucks.

Why the fuck is geany not on this list?
Fuck off and stop posting it. It's shit.

try VSCode, its better

show me how you actually use geany with some project that's not fizzbuzz and it will be in next poll

call me when Geany has extensions for every language, built-in github, a built-in shell, a built in debugger, extensive marcos, binds, emacs-like key combos with optional vim-input styles. And easy ricing and config via hot-loaded json values.

So I've been looking to get into 3D graphics in C++ with opengl/vulkan but I've been thinking whether I should do that or just learn how to 3D model?

Those a private methods. The reason the underscores are there is because there are already public methods with those names which wrap them.
_set is used in multiple locations which need access to the underlying cell which is why I factored that logic into a private method with such an ugly interface.

Abusing delegates is my choice to be honest. I think it keeps your function stack clean. You can easily use free functions instead. But Gtk event handling (like that of Java Swing) is heavily dependent on function pointers or delegates.

When I log into my Xenix system with my 110 baud teletype, both vi and Emacs are just too damn slow. They print useless messages like, ‘C-h for help’ and ‘“foo” File is read only’. So I use the editor that doesn't waste my VALUABLE time.

Ed, man! !man ed

ED(1) Unix Programmer's Manual ED(1)

NAME
ed - text editor

SYNOPSIS
ed [ - ] [ -x ] [ name ]
DESCRIPTION
Ed is the standard text editor.

---

Computer Scientists love ed, not just because it comes first alphabetically, but because it's the standard. Everyone else loves ed because it's ED!

“Ed is the standard text editor.”

And ed doesn't waste space on my Timex Sinclair. Just look:

-rwxr-xr-x 1 root 24 Oct 29 1929 /bin/ed
-rwxr-xr-t 4 root 1310720 Jan 1 1970 /usr/ucb/vi
-rwxr-xr-x 1 root 5.89824e37 Oct 22 1990 /usr/bin/emacs

Of course, on the system I administrate, vi is symlinked to ed. Emacs has been replaced by a shell script which 1) Generates a syslog message at level LOG_EMERG; 2) reduces the user's disk quota by 100K; and 3) RUNS ED!!!!!!

“Ed is the standard text editor.”

Let's look at a typical novice's session with the mighty ed:

golem$ ed

?
help
?
?
?
quit
?
exit
?
bye
?
hello?
?
eat flaming death
?
^C
?
^C
?
^D
?

---

Note the consistent user interface and error reportage. Ed is generous enough to flag errors, yet prudent enough not to overwhelm the novice with verbosity.

“Ed is the standard text editor.”

Ed, the greatest WYGIWYG editor of all.

ED IS THE TRUE PATH TO NIRVANA! ED HAS BEEN THE CHOICE OF EDUCATED AND IGNORANT ALIKE FOR CENTURIES! ED WILL NOT CORRUPT YOUR PRECIOUS BODILY FLUIDS!! ED IS THE STANDARD TEXT EDITOR! ED MAKES THE SUN SHINE AND THE BIRDS SING AND THE GRASS GREEN!!

When I use an editor, I don't want eight extra KILOBYTES of worthless help screens and cursor positioning code! I just want an EDitor!! Not a “viitor”. Not a “emacsitor”. Those aren't even WORDS!!!! ED! ED! ED IS THE STANDARD!!!

TEXT EDITOR.

When IBM, in its ever-present omnipotence, needed to base their “edlin” on a Unix standard, did they mimic vi? No. Emacs? Surely you jest. They chose the most karmic editor of all. The standard.

Ed is for those who can remember what they are working on. If you are an idiot, you should use Emacs. If you are an Emacs, you should not be vi. If you use ED, you are on THE PATH TO REDEMPTION. THE SO-CALLED “VISUAL” EDITORS HAVE BEEN PLACED HERE BY ED TO TEMPT THE FAITHLESS. DO NOT GIVE IN!!! THE MIGHTY ED HAS SPOKEN!!!

Fuck off

What possible use does contracts have when it's not even zero cost?
Why would the committee add this?

Contracts are just asserts with different syntax. The cost is the same either way - you turn them on while you debug and turn them off when you don't.

>Contracts are just asserts with different syntax.
no

Prove they aren't.

contracts are either executed before entering or after exiting a procedure. they are not part of the definition but of the declaration.

In C++20, that's what they are.
If a given predicate is not satisfied, the program raises an error - and whether this predicate is checked depends on a compile time flag. That's what an assert is.

See? asserts.
Just with different syntax and restrictions

You mean they're a part of function types?
std::is_same_v 0]]> == false?

IRC is quite dead. Would agree

Don't think so, otherwise it would be ambiguous which to call.
It's probably just the same situation as with noexcept before C++17. Not actually part of the type.

i mean that a contract shall not be part of the implementation.

int (*sort)(array *foo)
pre { foo != null }
post { isSorted(foo) == true };

That's not how shadows work

Attached: nice_dick.png (540x172, 106K)

You can put an [[assert]] in the implementation though

It's an approximation of global illumination.
It just has hard edges instead of soft edges.
The real question here is, what the fuck is Akari doing?

sort is a pointer, fuck tard. Contracts takes all their power when the implementation is unknown. UNKNOWN.

Wait, is what you posted valid C++20 syntax?
What does it do?

i am talking about the concept of programming with contracts in general. i don't know about c++ and i don't want to know.

Then stop talking about things you don't know about.

C++20 contracts don't use that syntax but roughly have those semantics.

Cppreference describes how they work nicely.

But can you use contracts with function pointers? That's what I wanted to know.

Doesn't look like it.

en.cppreference.com/w/cpp/language/attributes/contract

precondition: A precondition is checked by evaluating its predicate immediately before starting evaluation of the function body
postcondition: A postcondition is checked by evaluating its predicate immediately before returning control to the caller of the function
assertion: a condition that should be satisfied where it appears in a function body.

see, even without knowing c++, i was right. this is why it is important to learn programming techniques and concepts by reading PLT literature instead of how a specific programming language implement them.

>i was right
No you weren't. You can't use it with UNKNOWN implementations like you said.

Contracts are visible at the declaration site of a function.

Yeah and?
You can't use it with function pointers.

they are not dynamic but this is a limitation of C++. you can still do

... foo(...) ...;

and let someone else implement f

why?

no one cared about the Turing machine, his paper remained unnoticed for a long time.

turing was a fag
lambda calculus on the other hand was divinely inspired

Fuck off wrong thread.

Until it got noticed and became huge.
Face it, turing machines are just better and lend themselves well to being implemented as CPUs.
Lambda calculus is USELESS.

Agreed.

Fuck off still wrong thread.
