i set up my visual studio c# project on git by putting it in the folder with the .csproj, but any nuget packages i have are in the parent folder to this directory

Not really. I rarely need anything from nuget, C# comes with a pretty massive library. Maybe my projects just aren't cool enough though.

I know it's bait and you are mad because you got BTFO by C again, and your ass hurts because you will never be able to do anything more than a python script to fix your arch config
but I'm bored so I'll explain where you are wrong
someone else might find this information useful, eventhough it was explained about 10 times in this and the last thread already
>int avg = a + b / 2;
firstly you only divide b by two
not the sum of a and b
that's just a dumb error and I guess that's part of your ebic troll
so let's correct that
>int avg = (a+b) / 2;
now you still have the problem that the sum of those two integers inside the parenthesis has to be between −2147483648 and 2147483647, otherwise you get an overflow/underflow
alternatively you could divide the ints directly
>int avg = a/2 + b/2;
but in case a and/or b are not evenly divisible by 2 they get rounded and you lose that information and the result will be wrong
you could do something like
>int avg = (int) ((long double) a / 2.0 + (long double) b / 2.0)
that would work but you could still lose information due to the cast to a floating point number
I'm happy I could help
the solution posted above also only needs one cycle so it won't get any more efficient
What's the best way to store a cookie that will show the last 5 searches?
I think the best way to do it using an array, and appending to the array. This way I can keep it at a length of 5, and iterate through it easily.
I tried creating an array, then pushing the search ID to the array, then setting the array to the value of the cookie, but obviously the array will reset on refresh.
I then tried setting the array to the value of the array on load. But what if the cookie doesn't exist yet? So I added anif not nullcheck. Surely there's a better way though?

It would not be any problem adding a signed version, sign tests in hardware are basically free, you just route the sign bit into the next gate input.

The only reason they haven't added it is because it's not a useful operation so it would waste opcode and die space, but doing it in 1 cycle is no problem.

TIL matlab classes are immutable by default. I don't like that..

>>52965003
Adding new instruction typically has to be motivated by some use case.
But sure, you could do prime tests in one cycle, but it would be a very long cycle and everything else would be scaled back to it, or you'd need an insanely deep pipeline to get conventional throughput out of it at that clockrate.

what i want is the user to enter rain values for each month, and then he will have a list of options to choose from like the total amount of rain, least, average.....and the last one update.
on the update option, he can update the value of rain on the month he chooses. But he has to choose months 1-12. If he chooses 0, thats wrong and he has to choose again.

It can though (unsigned 16 bits).
And here's a patent describing exactly how to do a signed version in one cycle:
http://www.google.com/patents/US6007232?hl=de&dq=6007232
What about it is it your're having trouble understanding?
And I don't even understand why you think doing an integer average in one cycle is such an amazing feat, it can do other more intrinsically complicated things in half a cycle like fmas.

Right now you're inserting a double in the string-list.

You could just doif (o && o->update) o->update(o);
In general it seems that you are overusing continue.
What is o->update usually?
Are you sure that objects_size and o->ro_size are small enough to not cause lag?

Because I might add more things that would need to execute regardless if the object has an update function.
>In general it seems that you are overusing continue.
I don't think so.
>What is o->update usually?
Right now? updating coordinates and randomizing a texture.
>Are you sure that objects_size and o->ro_size are small enough to not cause lag?
If it was, it would be lagging at all times.
I think we've gone a bit off topic here, the problem is not in my code, the problem is SDL2 is delaying window resize events, I've confirmed this by putting a puts statement in theif (e.window.event == SDL_WINDOWEVENT_RESIZED)block and it never prints during resizing, only 1 or 2 seconds after i let go of the mouse button.
I have noticed that SDL_WINDOWEVENT_EXPOSED happens continuously during window resize and i tried using that to update window dimensions, and it works, but SDL2 still blocks keyboard input until the SDL_WINDOWEVENT_RESIZED event comes in.

>Because I might add more things that would need to execute regardless if the object has an update function.
And I might come into your house and rape your grandmother, but I am not doing that.

If you use continue at all, it is overuse. You kike nigger.
>>52966271
>And I might come into your house and rape your grandmother, but I am not doing that.
Except I probably will add more things to that function, nigger.

You sound like one of those HURR DURR GOTO IS BAD XD retards.
Fuck off.
>>52966283
Except that goto is actually useful as it might make your life easier in certain cases, continue is not.

>>52963012
Well Duke Nukem Forever finally released. Have faith.
>>52966300
Continue is more useful than goto.
How do you propose i skip the loop iteration if o is null huh faggot?
Enclosing everything in a dumb if block is not a solution.
>I doubt that you know how to do that.
If I see that I need to do something else in that function, I will do it and I'm sure I won't have much of a problem doing it dicknugget.
Is there any Java framework Rest which doesn't suck. With Jersey when I get to write the authentification filters it breaks. Spring documentation is a mess between the version changes.

I left them separate because there could possibly be some error handling or other code snippet that would only run if a particular branch failed.
Even then, your shitty "le goto is bad" solution still indents it one further than it should.

Okay now do it withclass Dog { }
I have code that I want to put on GitHub, why can't I just copy and paste it onto there? Instead you have to screw around with scripts. No this is not bait.
>>52966425
>le goto is bad
I think you are confusing me with the other person that claims that continue is better than goto. I never claimed that goto was bad.
>>52966362
Depending on task, I'd use the null-conditional operator. There's probably a better way to write that code anyway, you omitted too much.
>>52966426
>if you aren't going to use its features?
Features like continue?
>>52966432
git good.
No, really.
>>52966434
>other person that claims that continue is better than goto.
I think you're refering to me, I never said goto is bad, goto is fine, I'm just saying that continue is usually more useful than goto.
>>52966362
Not familiar with the language but couldn't you do this?String[] s;
/* ... */
for (int i = 0; (s && i < s.Length); i++) {
if (s == null) continue;
/* ... */
}
>>52966450
>I'm just saying that continue is usually more useful than goto.
This is exactly what I said that you said.
>>52966451
Nah if you check for s there you fall out of the loop on the first s that's null. You want to keep going through the loop but skip over all s'es that are null.
>>52966413
It actually compiles to je, jne, etc.
nice try.
>>52966460
You implied that I implied that goto was bad.
>>52966468
That's true, I misunderstood the question.
>>52966362
I just noticed that you're checking whether the whole array is null. Why having it in loop at all then? Write two loops.
>>52966479
You are right my bad, it's late here. I meant s[i]...
>>52966474
No, I didn't. Are you hallucinating?
C++ is the best programming language for the vast majority of non-trivial tasks. Prove me wrong... or... right.
String[] s;
/* ... */
for (int i = 0; (s[i] && i < s.Length); i++) {
/* ... */
}
Would this through an error if s is null? Would this work?
As expected /g/ gets carried away by stupid shit like continue instead of actually answering the question.
Isn't time you kids advance past fizzbuzz already and pick up a more complex project already?
It would be a good learning experience.

It will end the loop as soon as it encounters a null value.

Virtual machines are not easy, anon. In fact it's one of the hardest things to do.
Emulators are absolutely trivial.
But proper VMs that use VT-x/AMD-v? Ha, good luck with that. The simplest hello world example code is hundreds of lines.

>I didn't say x86 virtual machine, i just said virtual machine, it can be as simple as you want.
What you're thinking of is called an emulator. A virtual machine is the next level (running user code directly on the metal), and almost always involves hardware support.
>>52966570#include <stdio.h>
enum op
{
op_halt,
op_add,
op_load
};
unsigned char mem[0x100] = {op_load, 10, 1};
int
main (void)
{
for (size_t pc = 0; i < sizeof mem; i++)
switch (program)
{
case op_halt:
return 0;
case op_add:
mem[mem[++i]] += mem[mem[++i]]; /* I know, this is UB but whatever, fix it yourself */
break;
case op_load:
mem[++i] = mem[++i]; /* see above */
break;
}
return 0;
}

You can ask a legitimate question and still be a shitposting faggot.
>>52966626
>A virtual machine is the next level (running user code directly on the metal), and almost always involves hardware support.
Wrong.
Virtual machine and emulator are interchangeable terms.
I think the term you're looking for is hardware accelerated virtual machine.
Most people just use virtual machine as short term for hardware accelerated virtual machine, but that doesn't make them the same thing.
