It's dead code. I'm reading the RDTSC, I'm storing it. Later I'm reading RDTSC again and calculating something I don't use.
It's plainly dead code.
Would you expect your compiler to not eliminate dead code? It's as dead as code gets. It's this:int x=a; //a is declared elsewhere
//cycles pass
int b=x-a; //a has been/can have been altered
Note how b isn't being used and x is only used in calculating b.
This is exactly what's going on in my case except it's done inside a constructor/destructor. Would you expect a declared unused std::vector to just stick around when it's not used?

I've been to Islamic countries and I know for a fact that they are not forced to wear the hijab. The fact that they choose to wear it is just used to perpetrate the myth that they're not free not to wear it created by the islamophobic right.

Anon, please!
The funniest part is how you take issue with a radical Muslim minority forcing women to dress in a certain way but you don't say a word about the large majority of our hypocritical Western society shaming women into shaving their armpits or face social stigma.
It's almost as if you're not really worried about freedom, almost as if freedom's just a facade and a pretense and your real motives are racist and xenophobic.

It's the armpit shaving guy again. No one is coercing you into shaving your armpits, but it's the toll you pay to get your ass fucked.
When you're being intimidated into hijab, that's a little different. Not to mention hijab reduces women to chattel. You're not being turned into a sex slave by shaving your armpits, no matter how much you want to be one.

>I've been to Islamic countries
Which ones? Are they run by the Qur'an as we see in Iran and Saudi Arabia, or are they merely majority Islam like Turkey? Is there a culture of secularism, or is there a de-facto Islamism? Even if it's not illegal per se, it might be the case that your father or husband will beat you if you go out of the house without a hijab on. In some countries, notably Saudi Arabia, women cannot leave the house without permission of a male guardian, which may be her brother, father, or husband. Those men will almost always enforce the hijab requirement.

It's the most trivial shit anon.
Why are you curious? Because you're too stupid to understand it before despite my super concise explanation?struct ScopeTimer
{
unsigned long long startTime;
void endAction(unsigned long long){
//printf("FrameTime:%f\n",time);
};
ScopeTimer(){
unsigned int dummy;
startTime=__rdtscp(&dummy);
}
~ScopeTimer(){
unsigned int dummy;
unsigned long long endTime=__rdtscp(&dummy)-startTime;
endAction(endTime);
}
};
//Usage
ScopeTimer scopeTimer;
//Inside a block you wish to time
Maybe you'll learn something.
Now if I wanted to use this construct I have to make a macro, something like#ifndef _DEBUG
#define TIMERBLOCK(x) ScopeTimer (x);
#else
#define TIMERBLOCK(x)
#endif
And this is probably the most trivial case where RAII can be removed by the compiler. Can't imagine how much it shits up your code if you use that shit normally. It optimized away the call but it left in the instructions.

Let me ask you something: if you Google "Turkish women", how many of them are wearing a hijab? Not a ton. Probably about 1 in 10. Turkey has no Sharia law (although Erdogan is worrying, and they need another coup, preferably one that succeeds), but most of its population are Muslims. Of course the problem is separation of Church and State (or Mosque and State as it may be). The problem is that a lot of the middle east likes that idea of Islamic law.

Yeah, reading more about it it turns out that idiv uses a 64bit register combining EDX:EAX(apparently this is the notation for combined registers wew lad) so one has to extend the sign to the edx part using cdq(which I was missing).
It works now, fucking x86 documentation mang.
>>
>>61444288
Mostly.
If the type T is deduced, then the && is deduced either to an rvalue or lvalue ref as appropriate. Similarly, std::forward will pick rvalue or lvalue as appropriate rather than std::move which gives an rvalue

Right, and you expect a developer is going to be capable of producing a program that can do his job better than himself?

Managers don't know shit about programs, so the job of the developer is to fill in the blanks and ask questions. We suck at this, but an AI will be worse for quite a while.

I have a little more code on top of that because I prefer using lists instead of vectors, but yeah, bind is great. The one restriction is you can't pass struts, but instead pointers to struts.

If I were you, I'd do further abstraction. I can also tell just by looking at your methods that your program would run like shit.
If you have 1 million sprites on the screen, making 1 million calls to render per frame is going to commit a jihad on your performance. Hell your program would probably struggle with 10,000 sprites. Your program needs to do batched rendering, there's no point in using VBOs and in that case you should just use OpenGL 1.0.
Write your program to have a "client-server" relationship between the renderer and the high level code driving it, so that the renderer doesn't need to have information and instructions fed to it every frame, but the instructions just change what it is rendering.
Also what the fuck is a Texture*? Textures are just GLuints in OpenGL.
>>
>>61445844
>Your program needs to do batched rendering, there's no point in using VBOs and in that case you should just use OpenGL 1.0.
Left out an otherwise after batched rendering. Please don't use OpenGL 1.0 and write your program properly using techniques that aren't from the 90s.

It doesn't though. Sprites are instanced. Only draw() does the call. Notice how there's a single VBO.

render is a weird name for a method which registers a sprite to the vbo. How do you unregister sprites form the vbo.renderer->unrender(sprite);???
Texture management aren't really the duty of the renderer though. The renderer doesn't own textures just as it doesn't own sprites. The thread that create those sprites with those textures owns them.

So how do the sprites get updated in the VBO? glBufferData every frame? Persistent map? A persistent map leaves you very vulnerable to synchronization problems if you try to do the natural way OOP taught you to.
If the rendercomponents are the ones who copy the sprites to the vbo with glBufferSubData or non-persistent maps, then why are you registering the sprites to your renderer? And when do the rendercomponents update their data? When the actor updates them, or after all the actors have ticked? If it's when the actor updates them, then you're going to get fucked by synchronization.

Each RenderComponent knows its index (or rather the first of the 4 vertice).

The renderer was the one who knew where the corresponding texture was for the sprite and set the correct one. If I put the textures somewhere else it's no longer needed.

>>
>>61446673
Emacs is literally unusable without constant and unending fiddling with the emacs config, though. That's because of the core design of emacs: everything is ad-hoc. Making a plugin work with other plugins cannot happen without ungodly amounts of manual configuration. That's why bigger plugins have 30 subpackages specifically designed to adapt config for compatibility with other packages. But they understandably can't keep up with all the packages that exist, let alone tweaks to them, nor to updates to emacs.
For example, pop-win mode still doesn't know about a lot of core emacs *windows* which need to be manually added to its handling list, and it gets worse if you have any plugin that creates or modifies windows (think org-mode).

I have been studying http://higherorderfun.com/blog/2012/05/20/the-guide-to-implementing-2d-platformers/
I have been able to incorporate this code:float t = float(centerX - tileX) / tileSize;
float floorY = lerp( leftFloorY, rightFloorY, t );
float ceilY = lerp( leftCeilY, rightCeilY, t );
I think I understand it now that I have played around with it. However, this only resolves the y-axis, I still have a problem with the x-axis. I am not sure what the appropriate formula would be to use with the formula I have for vertical collision.

I'd just like to interject for moment. What you're referring to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!

>Can't run X program on it
That's not Redox's fault. If your program has a port for Redox, I don't see why won't they run on it.
This is like saying "Steam has no port for Linux so Linux can't run steam" in 2010

Why did Redox rip icons from iOS?

I believe these icons are called something like numix square or something. Redox being TRUE *nix, it does not have a de-facto icon theme

Erlang solves a very narrow domain of problems related to requiring separate processes that may fail, and how to recover.
Look at how you have to deal with strings and shit like that (math too) in erlang, and you'll realise that you're better off picking a language that better targets your problem space.
You'll be able to find examples of people implementing stuff they shouldn't in erlang, but there are always those kind of dipshits (on HN yesterday there was someone who'd built a neural net in erlang, i.e. they were multiplying matrices in a language that is known to be shit at that).

I never understand why someone would do something like that, or e.g. building a terminal emulator in js

For bash, take any shell scripting tutorial until you're somewhat comfortable.
Then forget %90 of it, take up the wooledge to tell you what you're doing wrong
http://mywiki.wooledge.org/BashPitfalls
And then pick up the GNU bash manual.
https://www.gnu.org/software/bash/manual/
Although I've never read it, Greg has a bash tutorial. It may or may not save the first 2 steps.
From what I can tell this guy is either a bash maintainer or just somebody who interjects too often on the bash mailing list, either way he knows bourne shells.

I watched the video few months back. He actually is pretty good. Apperently he works in system76 too. A true open source guy.
Too bad he's not edgy enough for /g/ so /g/ chooses to worship an autistic basement dweller that calls people nigger because it appeals to their mindset.

>>61447302
>He doesn't know that systemd follows the unix philosophy
And it's still shit.
The unix philosophy is a mistake.
Separating programs and piping data from program to program, with all the overhead that comes with it is a stupid fucking idea.
Running drivers in userspace is an even stupider fucking idea and offers NO advantage whatsoever. No seriously, there are only downsides, no upsides.
Having small and composable programs is wrong.
Having small and composable libraries is correct.
>Your kernelspace driver crashes
Your system is fucked
>Your userspace driver crashes
Your system is fucked
>Your kernelspace driver has not crashed
Your system runs fast, and is less complex
>Your userspace driver has not crashed
Your system runs slow, and is more complex (and therefore buggy).
Go back to sucking Tanenbaums microdick.

>>61447431
>Your userspace driver crashes

wtf!? Userspace drivers will reload without having to reload the fucking kernel.
>>
>>61447453
Yeah, and your system is still fucked regardless.

Nah, its mostly because Rust already has an infamous rep so most anyone associated with it will get written off.

I don't know what the meme with rust community is. There's the SJW subset of course but the actual useful part of the community produces generally pretty good content and doesn't seem to care about the coc bullshit, for instance.
>>
>>61447471
Yes, it is.
It doesn't matter if your disk driver is in userspace, your system is still fucked if it crashes and reloads.

Are microkernels the OOP of operating systems?
That is to say, fucking shit.
