Cheap Multiplayer Tricks for New Super Mario Bros. Wii

The New Super Mario Bros. Wii is a great game. Its the fun of old school Mario with the addition of great graphics and the kind of multiplayer I've wanted for Mario since playing the original as a child: its got up to four player simultaneous cooperative multiplayer. I recommend it to anyone who has enjoyed Mario in the past. Watch this amazing video of level 1-3 you can unlock in the game.

As noted elsewhere, multiple players attempting to navigate platforms, grab power ups, and throw turtle shells creates new challenges but along with that there's new ways to be incredibly cheap.

Jumping Higher

A second player means a head one can jump on to reach higher locations. Jump on your friend's head at the apex of their jump while holding down the jump button yourself for maximum jumping. In the game you can also grab other players and hold them over your head. This is useful for reaching the top of the flagpole at the end of levels. On that same line, if the player you grab has a flying cap you can now use them to fly in the same manner you would use a flying block which makes it easy to get two players to the top of the finish flagpole if only one of you has a flying cap.

Power-Ups

Normal power-up blocks now spawn enough power-ups for everyone. A mushroom is spawned for each small player and full power-ups for the rest, except in the case everyone is small: then one of the power-ups is a full power-up. If there's two players and you're both small, the full power-up always jumps out of the block to the right. Some hidden power-up blocks only give out one power-up and in that case its a mushroom or not based on the player who hits the block - so be sure that a big player hits that if you have one.

Death & Bubbles

When a player dies but at least one other player lives the dead player comes back in a limbo bubble from which they must be released before they may play again. Because of this, in a tough spot you can send one player in and leave a second behind. If the first dies you don't lose your place in the level and the first comes back in a bubble ready to try again. For instance, if you're trying to get the last star coin in 2-1 which sits just above the abyss, one player can just jump to their death for it and as long as another player lives you've collected the coin. However you need not sacrifice your life to do this: you can press down and 'a' to force yourself into a bubble saving yourself from death. This is true in general as long as you have enough time to see your death coming. This is also useful if one player runs ahead to the right. The screen will expand a bit but then it will just move to the right following the player in the lead. Players left behind walls or now forced into lava pits will die unless they use the bubble.

Misc.

• If all players hit the ground at the same time from a ground pound it acts like hitting a pow block, killing the enemies on the screen.
• If you hold a player who has a projectile power over your head they can still use their power.
• Bubbles can be popped by hitting them with your fire or ice projectiles as well as thrown shells or blocks.
• All players get the extra lives from anyone collecting 100 coins or finishing a level with more than 7 enemies on the screen.

A Brief History of Microsoft's Live Search's New Domain Bing

• 2003 July: The first archived version of bing.com features "bing! is a small device (e.g., possibly even a small Band-Aid(R)-like sticker!) that vibrates when a person's cell phone rings." I can't recall 2003 cell phones, were they big enough to require this device?
• 2004 August: Site for the same device is rewritten and looks much better, IMHO.
• 2006 June: The domain is now parked by easyDNS. I guess the "bing!" device didn't work out?
• 2006 November: Its now "BING*" and they won't say what they're working on ("we're still in stealth mode") but they are hiring C#/.NET developers.
• 2007 January: And they're gone. Without even exiting stealth mode. Too bad, I liked their logo. Their domain is now for sale...
• 2007 February: Looks like EasyMail buys the domain and offers a physical mailing service in Australia: "By simply clicking a button on your computer, mail is beamed electronically to a bing post office. Your mail is automatically printed, folded, enveloped and dispatched into the Australia Post network the very same day."
• Present: Now its the new home for Live Search of course.

The new name reminds me of the show Friends. Also, I hope they get a new favicon - I don't enjoy the stretched 'b' nor its color scheme.

Thoughts on registerProtocolHandler in HTML 5

I'm a big fan of the concept of registerProtocolHandler in HTML 5 and in FireFox 3, but not quite the implementation. From a high level, it allows web apps to register themselves as handlers of an URL scheme so for (the canonical) example, GMail can register for the mailto URL scheme. I like the concept:

• Better integration of web apps with your system.
• Its easy for web apps to do.
• Links to URNs can now take the user to the sites the user prefers for the sort of thing identified by the URN. For example, if I have a physical address in HTML, instead of making that an http link to Yahoo Maps, I can make the link a geo scheme URI and those who follow the link will get their preferred mapping site that has registered for that scheme. Actually, looking at the geo scheme's RFC, maybe I'd rather use some other URN scheme to represent the physical location, but you get the point.

• There's no way to know if you are the handler for a particular URL scheme which is an important question for web app URL protocol handler authors.
• There's no way to fallback to an http URL in the case that a particular URL scheme isn't registered. A suggested solution to testing the registration of a scheme is for browsers to provide an additional script method to check if a scheme is registered. I don't like the idea of writing script that walks over all my page's links and rewrites them based on that method. I'd much rather see a declarative and backwards compatible fallback mechanism, although I don't know what that would look like.
• There's no way to register for a namespace within the urn scheme URI, the info scheme URI, or the tag scheme URI. I want to register info:lccn/... (Library of Congress Card Number identifiers) to LibraryThing or Amazon and I want to register urn:duri:... (dated URIs) to the Web Archive, among other things.


• Will this result in a proliferation of unregistered URL schemes with clashing namespaces? The ESW Wiki notes why this would be bad.
• And last, although this is nitpickier than the rest, I don't like the '%s' syntax used in the registration method. I'd much rather pass in an URL template, like the URL template used in OpenSearch. If an URL template is used for matching rather than registering against a particular URL scheme, this could also allow for registering a namespace within a URN. For example something along the lines of: registerProtocolHandler("info:lccn/{lccnID}", "htttp://www.librarything.com/search_works.php?q={lccnID}", "LibraryThing LCCN")

Back from California

Sarah and I are back from a short Christmas visit to California. We spent the days around Christmas with much of my extended family in Sacramento many of whom I had not seen in quite a while. It was nice to see everybody again. I ended up taking a few pictures on Christmas in order to add to the digital photo frame I gave Grandma.

We flew in and out of San Francisco on Virgin America which was really nice. The staff is trying their best to be hip but accessible, the safety instructional video is entertaining, there's mood lighting, and all seats have entertainment systems as well as power outlets and USB ports to charge your electronic devices. They don't have many flights which appears to mean shorter lines. And it was cheaper to fly with them and then rent a car and drive to Sacramento then to fly in to Sacramento. I'll for sure be flying with them again given the opportunity. Before flying back Sarah and I spent a day in San Francisco, where we decided that if we don't go back to Fisherman's Wharf again in this lifetime that would be acceptable, saw the Golden Gate Park and met up with my friend Jake who I haven't seen in at least four years. Next up, happy new year!

Danger to Life

The English portions of the signs read "dangerous. Climbing on and over the balustrades and railings stictly prohibited. Daner to Life! Any violation will result in criminal prosecution!"
