Replacing a stub with a redirect.[edit]

There is a virtually empty stub for Puerto Pollensa and a slightly more developed stub for Port de Pollença. The former is Castellano, and the latter is Catalan, for exactly the same town. The page Puerto Pollensa should be replaced by a redirect to Port de Pollença. Is this something I can do (if yes, how?), or must one be an administrator? --NorwegianBlue^talk 19:26, 16 June 2006 (UTC)[reply]

I've done it in this case with http://en.wikipedia.org/w/index.php?title=Puerto_Pollensa&diff=58994624&oldid=52731902 this edit]. All you need to do is delete the content of the page and replace it with #REDIRECT [[Port de Pollença]]. --Cherry blossom tree 20:03, 16 June 2006 (UTC)[reply]

New section tab[edit]

How do I add a "new section" tab to a subpage of my userpage? Thanks. --NorwegianBlue^talk 18:34, 17 November 2008 (UTC)[reply]

If I understand correctly, "new section" is available on talk pages, but not user pages. If anyone else has a more specific answer though, that would be great. TN‑X-Man 18:38, 17 November 2008 (UTC)[reply]

Well, the reference desk pages have such tabs, and they're not talk pages...(?) --NorwegianBlue^talk 18:40, 17 November 2008 (UTC)[reply]

Use the magic word __NEWSECTIONLINK__ (note double underscores). Algebraist 18:41, 17 November 2008 (UTC)[reply]

Collapsing template[edit]

Folks, what's the wikipedia template for collapsing a big run of stuff (that might not be of interest to everyone) with a show/hide thing? I'm going to post some code in reply to the css menu question at the bottom, but I'm concerned that this'll make the quesion and answer sprawl annoyingly for folks who're just skipping over to something they care about. Thanks. 87.112.81.29 (talk) 14:26, 14 February 2009 (UTC)[reply]

The simplest way is this:

Title
Content

Better version with width 100%[edit]

Some C++ code I used when answering a question.

double question1()
{
	std::vector<double> p; // Probabilities in previous iteration
	std::vector<double> q; // Probabilities in current iteration
	p.resize(100);
	q.resize(100);

	int i;
	for (i = 0; i < 100; ++i)
	{
		p[i] = 0.0;
	}

	// Situation after two throws
	p[0] = 1.0/100.0;
	p[1] = 99.0/100.0;

	for (i = 2; i < 100; ++i)
	{
		int j;
		for (j = 0; j < 100; ++j)
		{
			q[j] = 0.0; // Reset
		}

		q[0] = p[0]/100.0;
		for (j = 1; j <= i; ++j)
		{
			q[j] = p[j]*(j+1)/100.0 + p[j-1]*(100.0-j)/100;

		}

		// Verify that total probability is 1.
		double tot_prob = 0.0;
		for (j = 0; j < 100; ++j)
		{
			tot_prob += q[j];
		}
		std::cout << "Iteration: " << i+1 << ", Total probability: " << tot_prob << '\n';

		p.swap(q); // Prepare for next iteration
	}

	// Calculate expectation (of number of numbers that have appeared)
	double u = 0.0;
	for (i = 0; i < 100; ++i)
	{
		u += (i+1.0)*p[i];
	}
	return 100.0 - u;
}
