What are you working on? V10

[BAZ]

Yeah I know you could do it by only considering the whole numbers but it would be much easier for the consumer if they could just see them by eye.

You should add some kind of linear programming to it, might take a bit of reading to understand it, but it'll definitely be useful for someone.

There's a line where I have to just stop with the features or this will never get release. Linear programming is a huge topic, and it is definitely not worth it at the moment. If anything, I should add regression calculations, intersections, and stuff like that.

Also, just finished conditional plots, which you can use for piecewise plots:

I wasn't suggesting putting it in right now, it was just a suggestion for a later date. It looks more complicated than it really is.

Finished my calculator.

It's exactly 510 bytes and supports addition, subtraction, multiplication and warns on overflow.

[Dr Magnusson]

Spent the past 8 to 10 hours buried neck-deep in Assembly websites, learning it properly.

Written some handy functions for printing strings or characters, along with getting keyboard input. Without using interrupts.

My head feels weird.

[luck_or_loss]

I'm gonna sell my TI-84+ Silver Edition calculator with sweet blue case and faceplate and only use Null's when it comes out.

also Null would it be possible to render 3d volume as transparent planes layered on the x y and z axis?

[NorthernGate]

Really been trying to put a game idea of mine down. But for some reason the Release DLL version of SFML doesn't output any libs for me to connect to. I really don't want to do this on 2008, can someone tell me what's wrong? ( Using 2010 Studio )

[Blade]

Was wondering why when my dll was being unloaded it wouldn't unhook itself.

Forgot that the singleton I had was storing as a raw pointer. Changed it to a shared pointer.

The below works but is there anything that should be changed?

[cpp]template <class T>
class Singleton
{
private:
static boost::shared_ptr<T> singleton;
public:
static void New()
{
if (!singleton)
singleton.reset(new T());
}
static void Delete()
{
if (singleton)
{
singleton.reset();
}
}
static boost::shared_ptr<T> Self()
{
if (!singleton)
singleton.reset(new T());
return singleton;
}
};

boost::shared_ptr<T> Singleton<T>::singleton;[/cpp]

Make a private empty constructor and private operator new and delete. This way you ensure that other have to use Self(), New() and Delete().
Couldn't you also delete the pointer in the dlls entry-point upon DLL_PROCESS_DETACH?

Huh? New/Delete are just there because in some project I needed to manually Delete the singleton.

Yes, but it is a pain to do that for several singletons and remembering to do it.

Is it really worth it learning assembly?

[QUOTE=Dlaor;22231019]Is it really worth it learning assembly?[/QUOTE]

Depends, if you are just interested in doing funny windows apps, there is not a point in it really. Making a kernel and boot loader for fun, you need to know assembly. Really depends on what you like to do.

There are a lot more benefits to learning assembly then just being able to write it.

If you have an interface that all singletons inherit from you could keep a global list of them for deletion upon DLL_PROCESS_DETACH.
A shared_pointer is fine too though ;)

I'd still declare the stuff i mentioned private to prohibit uncontrolled instantiation.
With operator new and delete I didn't mean you New and Delete functions ;)

Is anyone still looking for the LÖVE wiki? If so, [url=http://web.ics.purdue.edu/~dcfritz/lovewiki/][u]here[/u][/url] is a copy.

[turb_]

The OS Dev wiki is insanely helpful:

[url]http://wiki.osdev.org[/url]

[editline]09:42PM[/editline]

And yeah, you should learn assembly.

These days it's rather nichey and useless to most people, but it is really fun to use and helps you understand a lot more about computers if you know assembly.

[QUOTE=luck_or_loss;22229159]also Null would it be possible to render 3d volume as transparent planes layered on the x y and z axis?[/QUOTE]

Um, technically, yes, but:
- it'll look ugly unless there's a LOT of planes
- it'll be hard to approximate the exact volume which may have a certain shape to it

Yeah, get rid of the singleton. If you didn't put it there in the first place you wouldn't have had this issue.

What's a good way to document an API (.NET)?

The documentation for an API I'm working with is horrendous, so I want to make notes as I'm going along -- notepad isn't quite cutting it any more.

[Robert64]

Got most of my UI system ported from AS3 to C#:
[img]http://i50.tinypic.com/30123vp.png[/img]

Is this a good interface?

test_frame = new UIMenu(
    32, 32, 192, 256,                // X, Y, Width, Height
    "Main Menu", "border", "large",  // Title, Frame style, Title font style
    "default", "default",            // Option border style, Option font
    Color.White, true                // Colour, autosize
);

test_child = new UITextBox(
    256, 48, 192, 128,            // X, Y, Width, Height
    "default", true               // Frame style, Typewriter effect
);

test_child.SetText( Res.GetItem<RText>("test_text").Text, "large", Color.Black );

test_frame.AddOption( "Test text box", this.GetType().GetMethod( "TestTextBox" ), this );
test_frame.AddOption( "Quit",          this.GetType().GetMethod( "Exit" ),        this );

...

public void TestTextBox()
{
    test_frame.SetChild( test_child );
}

[turb_]

No. Make all those options properties if they aren't already, so you can do shit like:

new UIMenu {
    Left = 0,
    Top = 0,
    Title = "foobar"'
};

I guess you were trying to get around the "switch expression of type 'std::string' is illegal" error with that weird char stuff, but that's generally a bad idea, you can't just circumvent the underlying problem.

You can't use strings in switch statements; a switch statement uses integer values.
