Well, it looks like Cemetech has a new template (or theme if you prefer). It's a retro theme and it looks you have both the OS mouse and a 84+ SE mouse!

Here's a picture of it:



I'd check it myself if I were you to see the 84+ SE mouse effect.


I first thought this was just an experiment, but it seems like it is somewhat permanent:

<KermOffc> back at the office
<KermOffc> TechNOM76, , Scout , it's not temporary
<KermOffc> I'm sorry to hear you guys don't like it

It also seems like it's not an April Fools Day joke:

Edit: And yes, I know that it's April 1st; it's an unfortunate coincidence, but I assure you no less real.

To sum up, it's nice to see both TI Freakware and Cemetech are getting new themes and changing their forums, I hope this helps keeping the TI Community young.

Last night, I installed wxWidgets 2.9.1 on my Ubuntu 10.04. It all went well, and it works:

david@DavidPC:~$ wx-config --version
2.9.1
david@DavidPC:~$

It was installed. Now I want to make my first GUI program, and used this code:

/*
 * hworld.cpp
 */

#include "wx/wx.h"

class MyApp: public wxApp
{
    virtual bool OnInit();
};

class MyFrame: public wxFrame
{
public:

    MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size);

    void OnQuit(wxCommandEvent& event);
    void OnAbout(wxCommandEvent& event);

    DECLARE_EVENT_TABLE()
};

enum
{
    ID_Quit = 1,
    ID_About,
};

BEGIN_EVENT_TABLE(MyFrame, wxFrame)
    EVT_MENU(ID_Quit, MyFrame::OnQuit)
    EVT_MENU(ID_About, MyFrame::OnAbout)
END_EVENT_TABLE()

IMPLEMENT_APP(MyApp)

bool MyApp::OnInit()
{
    MyFrame *frame = new MyFrame( _("Hello World"), wxPoint(50, 50),
                                  wxSize(450,340) );
    frame->Show(true);
    SetTopWindow(frame);
    return true;
}

MyFrame::MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size)
: wxFrame( NULL, -1, title, pos, size )
{
    wxMenu *menuFile = new wxMenu;

    menuFile->Append( ID_About, _("&About...") );
    menuFile->AppendSeparator();
    menuFile->Append( ID_Quit, _("E&xit") );

    wxMenuBar *menuBar = new wxMenuBar;
    menuBar->Append( menuFile, _("&File") );

    SetMenuBar( menuBar );

    CreateStatusBar();
    SetStatusText( _("Welcome to wxWidgets!") );
}

void MyFrame::OnQuit(wxCommandEvent& WXUNUSED(event))
{
    Close(TRUE);
}

void MyFrame::OnAbout(wxCommandEvent& WXUNUSED(event))
{
    wxMessageBox( _("This is a wxWidgets Hello world sample"),
                  _("About Hello World"),
                  wxOK | wxICON_INFORMATION, this);
}
My question being, how to compile it?

When I go to the console and type g++ helloWorld.cpp I get:

No idea why though

A pitagoric triplet is, as most of you know, a group of numbers a,b,c that solve the following rule:

a²+b²=c²

The most common example is 3²+4²=5².

The challenge is the following:

a²+b²=c²
a,b,c are all natural numbers
a+b+c=200

You can easily find the answer on the Net, but I want the mathematical (by hand) proof of your work.

Good Luck! If you find the answer like some already did, post it in spoiler tags please.

I just saw on the news, France shot a tank on Libya due to Khadafi's refuse of a reserved air space.

I'm afraid this might mean war :S

What do you think?

Introductions
Gamers, programmers, and a lot of internet users recently found out about nDoom and everybody wants to play it.

Setting up nDoom on a TI-NSpire can be difficult, hence I decided to write this article/tutorial on how to install and set up nDoom for the TI-NSpire Touchpad (and Clickpad, but I'm focusing on the Touchpad).

What do you need
To run Assembly/C programs like nDoom on the NSpire you need a TI-NSpire, NDless, TI-Nspire™ Computer Link Software, a USB cable to connect your NSpire to your computer and nDoom.

Setting up NDless
I didn't mention one thing you need in the previous paragraph, on purpose, because I want to explain it in separate. nDoom only works with NDless 2.0, which only works with TI-NSpire Operative Systems 2.x. This is, the Operative Systems that will work are all the ones that are of the type 2.x. I recommend 2.0.1, since it worked perfectly for me in my Touchpad, but I think the others will work as fine.

The first thing you need to install (and I can't help you with it) is the TI-Nspire™ Computer Link Software. Anyone who has ever installed a program on their computer will make it through easily (press 'Next' a hundred times).
Note: This software is only available for Windows and Macintosh.

After installing TI-Nspire™ Computer Link Software, connect your calculator to your computer and turn it on. Then open the software and, hopefully, a dialog will show up asking you to confirm which calculator you want to connect to. Connect.

Now you need the OS 2.0.1 (if you don't have it already, and you can check which OS you have by, in your calculator, going to the definitions menu and pressing State, this shouldn't be too hard). In case you don't have the OS you need, you can get it here. More OSs can be found here.

Now browse to the folder where your .tno file is, and drag and drop it to the Computer Link Software:



A popup will ask you if you really want to install the OS, do not disconnect your calculator until it is installed. The progress bar starts on the computer but will keep on to the calculator later.

Now that you have the proper OS you can install NDless. The version I used can be found here. It worked for me, but if you want the latest version of Ndless, you have to go here and download the 'latest' folder.

Whichever version you use, transfer the following files to your calculator (the same way you transferred the OS):
ndless_resources.tns;
ndless_installer_os-2.0.1.tns; //This may depend on your OS, but if you did just as I said in this tutorial, this is the one

Setting up nDoom

While it is true that nDoomis still beta, an 'executable' and very stable version of it is available. You can find it here.

Transfer all of the files in the folder downloaded (after extracting them of out of the .zip) to your calculator, the same way you did with the OS and NDless.

Now you have to unplug your calculator from the computer, but check if you have the ndoom_b1.tns and doom1.wad files on it. Recheck if you have the ndless installer and resources files.

Don't forget to unplug.


Really.

Now, hopefully, you have everything you need. Open your calculator, find the ndless_installer_os-2.0.1.tns file and open it. If everything is OK, a 'Sucess' message will show up and you can then open ndoom_b1.tns and play nDoom!

If the screen goes crazy, check if you have ndless_resources.tns on it (it happened to me).
If still not working, retry the tutorial or respond to this topic, since me or someone else can help you.

Thanks to...

Thanks to the NDless development team for creating NDless and making an awesome readme.txt (I read it!) which thought me how to do this.
Thanks to Mrakoplaz for creating nDoom.

In the 8x Series I can:
Y1= (2.5X)(X>10)
Y2 = (5X)(X<=10)
This meaning:
If x>10, y=2.5x
If x<=10, y=5x

How can I do this on the nspire?

<!DOCTYPE html>
<head>
<script language="javascript" type="text/javascript">
function addtext() {
var newtext = document.myform.inputtext.value;
document.myform.outputtext.value += newtext;
}
</script>
</head>
<body>
<form name="myform">
<input type="inputtext" size="25" />
<input type ="outputtext" size = 25" />
<p></p>
<input type="button" value="Convert" onClick="addtext();">

</form>
</body>
</html>
I have this code which is supposed to pick the text from the inputtext textbox and put it in the outputtext box. It is not working though, any ideas?

I think that in OmnomIRC our link to the rules is bit.ly and I am in favour of having links in that super cool omniurl.tk

I think it looks better, what do you think?
