For now, I wrote a little class that generates wav files when fed morse code. I've set up a page that will simply return the result based on the url parameters. Change 'morse' and 'speed' (wpm) to whatever you want them to be. It accepts . for dit, - for dah, and spaces for a dit-length delay.

http://innerdvations.com/demos/morser/audio.php?speed=30&morse=.. -. -. . .-. -.. ...- .- - .. --- -. ... .-.-.- -.-. --- --

I'll post the source code later this week once I clean it up a bit and release some other morse code related stuff.

Some of the problems:

1. long lines are cut off when javascript is disabled
2. unpredictable behavior (depending on css) using <pre> without <code>
3. no syntax highlighting
4. no line numbers
5. pixel font sizes should be ems
6. widths shouldn't be hard-coded javascript
7. should be an optional max width property
8. able to set tab size somewhere
9. no source code available (other than the tutorial itself)

So, I took a bit of the original code and then rewrote most of it to do all of the above. jQuery is required (though with javascript disabled, #1 and #2 have still been fixed). #3 requires Google Code Prettify, but that's totally optional.

Here are some examples with the different options:

// really long block with just <pre><code></pre></code>
	wp_register_style(self::$plugin_stylesheet_id, WP_PLUGIN_URL . '/' . dirname(plugin_basename(__FILE__)) . '/admin-styles.css' );
	wp_enqueue_style(self::$plugin_stylesheet_id);
	wp_register_script(self::$plugin_script_id, WP_PLUGIN_URL . '/' . dirname(plugin_basename(__FILE__)) . '/admin-scripts.js' );
	wp_enqueue_script(self::$plugin_script_id);

// uses max-width
	wp_register_style(self::$plugin_stylesheet_id, WP_PLUGIN_URL . '/' . dirname(plugin_basename(__FILE__)) . '/admin-styles.css' );
	wp_enqueue_style(self::$plugin_stylesheet_id);
	wp_register_script(self::$plugin_script_id, WP_PLUGIN_URL . '/' . dirname(plugin_basename(__FILE__)) . '/admin-scripts.js' );
	wp_enqueue_script(self::$plugin_script_id);

// with class noprettyprint
	wp_register_style(self::$plugin_stylesheet_id, WP_PLUGIN_URL . '/' . dirname(plugin_basename(__FILE__)) . '/admin-styles.css' );
	wp_enqueue_style(self::$plugin_stylesheet_id);
	wp_register_script(self::$plugin_script_id, WP_PLUGIN_URL . '/' . dirname(plugin_basename(__FILE__)) . '/admin-scripts.js' );
	wp_enqueue_script(self::$plugin_script_id);

// with class nolinenums
	wp_register_style(self::$plugin_stylesheet_id, WP_PLUGIN_URL . '/' . dirname(plugin_basename(__FILE__)) . '/admin-styles.css' );
	wp_enqueue_style(self::$plugin_stylesheet_id);
	wp_register_script(self::$plugin_script_id, WP_PLUGIN_URL . '/' . dirname(plugin_basename(__FILE__)) . '/admin-scripts.js' );
	wp_enqueue_script(self::$plugin_script_id);

Since what you're seeing on this site at the moment is an old hacked together version,
here's a demo page I've set up where you can see all the different options and download the source.

To get the translated role names that are already included in WordPress, use translate_user_role() on that full English name rather than translate_with_context().

I don't know why it's virtually undocumented, so it's possible there's a negative to doing it this way, but that's actually the function used by core to get the translated dropdown menu.

I had an idea for a dumb game so I made it.

Now, I realize that even assuming someone would want to actually read YouTube comments is a stretch. That's probably why nobody has ever noticed this bug before -- I'm probably the first person to actually read a comment on YouTube. So that you don't have to do so as well, I've taken a screenshot of the issue:

YouTube comments as displayed by Opera

If you want to see how your own browser renders an inline BOM, I've put them in brackets here:
[] (using &#65279;)
[] (the actual character itself)

If you use Firefox or Chrome, you probably don't see anything. In fact, the second one is probably even completely missing when you view source. I'm guessing that rather than treat it as a "zero-width non-breaking space" they assume there's an out-of-place BOM and trash it altogether.

YouTube comments as displayed by Lynx, proving I'm not imagining things

So, whose fault is this? As I understand it, it's Opera's fault, because it should be displayed as a zero-width space, but YouTube should share a good portion of blame for sticking a BOM, which is only supposed to appear as the first character in a document, in the middle of content. I can't think of a single reason for any of them to be there... they're not joining words, they're not doing any sort of strange character set handling. Additionally, Opera could have a security argument for visibly rendering it, since it's one of those characters that phishers like to use to make something appear legit when it's not.

Anyway, here's how to fix it (if you're like me and you use Opera and are driven crazy by insignificant little details). All you need to do is go to Site Preferences, Scripts, set a user-script directory, and then put this file or create a .js file with this in it:

last_clean = new Date().getTime();
function clean_youtube_comments() {
	// if the element we're cleaning doesn't exist, don't try cleaning it
	if (!document.getElementById('comments-view')) {
		return;
	}

	original = document.getElementById('comments-view').innerHTML;
	cleaned = document.getElementById('comments-view').innerHTML.replace(/[]*/gi,'');
	// make sure we should actually replace it
	if(original != cleaned && original.length >= cleaned.length && cleaned.length) {
		document.getElementById('comments-view').innerHTML = cleaned;
		last_clean = new Date().getTime();
	}
}

function yt_DOMNodeInserted() {
	// if we cleaned less than 50ms ago, skip it. this prevents cleaning
	// multiple times on paging, because DOMNodeInserted gets called for
	// each node inserted, which amounts to about 5 times in a row in
	// this case.
	now = new Date().getTime();
	if(now - last_clean < 50) {
		return;
	}
	clean_youtube_comments();
}

addEventListener('load', function (e) {
  // clean on page load
  clean_youtube_comments();
  // clean on DOMNodeInserted (listener for the ajax paging of comments)
  document.getElementById("watch-discussion").addEventListener("DOMNodeInserted", yt_DOMNodeInserted, false);
}, false);

Updated 2011-08-27: It took a week before I had the urge to view a second page of comments and realized it didn't catch those, so I've had to add a listener for YouTube AJAX paging.
