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.

Grocery Shopper Data Use

QFC, the grocery store closest to me, has those irritating shoppers cards. They try to motivate me to use it with discounts, but that just makes me want to use a card, I don't care whose card and I don't care if the data is accurate. They should let me have my data or make it useful to me so that I actually care.

I can imagine several useful tools based on this: automatic grocery lists, recipes using the food you purchased, cheaper alternatives to your purchases, other things you might like based on what you purchased, or integration with dieting websites or software. At any rate, right now all I care about is getting the discount from using a card, but if they made the data available to me then the grocery store could align our interests and I'd want to ensure the data's accuracy.

Time/Date Conversion Tool

I built timestamp.exe, a Windows command line tool to convert between computer and human readable date/time formats mostly for working on the first run wizard for IE8. We commonly write out our dates in binary form to the registry and in order to test and debug my work it became useful to be able to determine to what date the binary value of a FILETIME or SYSTEMTIME corresponded or to produce my own binary value of a FILETIME and insert it into the registry.

For instance, to convert to a binary value:

[PS C:\] timestamp -inString 2009/08/28:10:18 -outHexValue -convert filetime
2009/08/28:10:18 as FILETIME: 00 7c c8 d1 c8 27 ca 01

Converting in the other direction, if you don't know what format the bytes are in, just feed them in and timestamp will try all conversions and list only the valid ones:

[PS C:\] timestamp -inHexValue  "40 52 1c 3b"
40 52 1c 3b as FILETIME: 1601-01-01:00:01:39.171
40 52 1c 3b as Unix Time: 2001-06-05:03:30:08.000
40 52 1c 3b as DOS Time: 2009-08-28:10:18:00.000

[PS C:\] timestamp -inHexValue  "40 52 1c 3b" -convert guess
40 52 1c 3b as DOS Time: 2009-08-28:10:18:00.000

When I first wrote this I had a bug in my function that parses the date-time value string in which I could parse 2009-07-02:10:18 just fine, but I wouldn't be able to parse 2009-09-02:10:18 correctly. This was my code:

success = swscanf_s(timeString, L"%hi%*[\\/- ,]%hi%*[\\/- ,]%hi%*[\\/- ,Tt:.]%hi%*[:.]%hi%*[:.]%hi%*[:.]%hi", 
&systemTime->wYear,
&systemTime->wMonth,
&systemTime->wDay,
&systemTime->wHour,
&systemTime->wMinute,
&systemTime->wSecond,
&systemTime->wMilliseconds) > 1;

To convert between these various forms yourself read The Old New Thing date conversion article or Josh Poley's date time article. I previously wrote about date formats I like and dislike.

Creating Accelerators for Other People's Web Services

Before we shipped IE8 there were no Accelerators, so we had some fun making our own for our favorite web services. I've got a small set of tips for creating Accelerators for other people's web services. I was planning on writing this up as an IE blog post, but Jon wrote a post covering a similar area so rather than write a full and coherent blog post I'll just list a few points:

• The first thing to try is looking for developer help for the web service, specifically if there's a REST-ful URL based API. For example, Bing Maps has great URL API documentation that would be enough to create an Accelerator.
• The Accelerator XML is very similar to HTML forms. If you can find an HTML form for the web service for which you want to create an Accelerator, you can view the HTML source and create an Accelerator based on that.
• I created the FormToAccelerator extension based on the previous idea. You can use the extension to create an Accelerator from an HTML form, or just use it to create the start of one and edit it manually after.
• If the page doesn't use an HTML form, you can start up an HTTP debugger like Fiddler, use the web service from the normal web page, and then in Fiddler see if you can find a REST-ful looking URL you can use.
• When looking to create a preview for your Accelerator, see if the web page for the web service has a mobile version or a version that's intended to embed in other web pages via an iframe. On this same line, iPhone apps make great Accelerators usually with lovely previews.
• If there's no mobile or embeddable version and the only thing wrong with the normal web page for the web service is that the useful information doesn't fit in the preview window then see if you can find an HTML tag with a name or id near the useful information, and stick a '#' fragment pointing to that tag onto the preview URL template.
• Without a reasonable REST-ful API you can use a combination of Google's "site:" and "I'm Feeling Lucky" to find the most relevant page on a particular site.
• The value of a name and value pair need not consist of only a single Accelerator variable. You can get creative and put other text in there. For instance, I implemented a Google currency conversion by setting the query to "{selection} in US Dollars".

IE8 Search Providers, Accelerators, and Local Applications Hack

There's no easy way to use local applications on a PC as the result of an accelerator or a search provider in IE8 but there is a hack-y/obvious way, that I'll describe here. Both accelerators and search providers in IE8 fill in URL templates and navigate to the resulting URL when an accelerator or search provider is executed by the user. These URLs are limited in scheme to http and https but those pages may do anything any other webpage may do. If your local application has an ActiveX control you could use that, or (as I will provide examples for) if the local application has registered for an application protocol you can redirect to that URL. In any case, unfortunately this means that you must put a webpage on the Internet in order to get an accelerator or search provider to use a local application.

For examples of the app protocol case, I've created a callto accelerator that uses whatever application is registered for the callto scheme on your system, and a Windows Search search provider that opens Explorer's search with your search query. The callto accelerator navigates to my redirection page with 'callto:' followed by the selected text in the fragment and the redirection page redirects to that callto URL. In the Windows Search search provider case the same thing happens except the fragment contains 'search-ms:query=' followed by the selected text, which starts Windows Search on your system with the selected text as the query. I've looked into app protocols previously.

Dave's Blog Entries Last Year

Inspired by one of Penn's (of Penn & Teller) articles in which he mentions he has his computer tell him what he wrote in his journal that day the previous year, I've wanted to implement a similar thing with my blog. Now that, as I mentioned previously, I've updated my blog such that its much easier to implement search and such, I've added date range filtering to my site's search. So now I can easily see what on Delicious and my blog I was doing last year.

I've also otherwise updated search on this site. You can now quote terms to match an entire string, stick 'tag:' in front of a term to only match that term against tags as opposed to the title and body of the entry as well, and you can stick '-' in front of a term to indicate that it must not be found in the entry.

Baseball Game Friday, House Things Previously

On Friday Sarah and I went to the Mariners vs Rangers game at Safeco Field with Eric and Jane. The Mariners lost but then before the game the announcement made outside the stadium guaranteed the best service and a good time, not a winning game -- and they were right about the good time.

The night before, we saw The Hangover which was very funny and included Zach Galifianakis who was great. Incidentally, take a look at some of Zach's Between Two Ferns.

Last weekend Sarah and I mounted the TV to the wall which was exciting and we saw a mouse in the house!

Eat Pants - Interactive Fiction Sessions from my Server Logs

I've looked at my web server logs previously to see if anyone had used my Web Frotz Interpreter and until recently didn't realize that awstats (the web server log report generator) was truncating the query from my URL, so I couldn't tell that anyone was actually using it. But after grepping the logs manually I've pulled out the URLs of visitor's text adventure sessions. If you'll recall, my Web Frotz Interpreter stores the game state in the URL so its easy to see user's game states in the web server logs.

I've put some of the links up on the Web Frotz Interpreter page. Some of the interesting ones:

• Apparently you can eat pants in Lost Pig.
• Someone teaches me that in Zork the egg goes in the display case.
• There's a creepy exchange in Galatea.

Linking to or Embedding a Portion of a Video

I'm excited by HTML5's video tag as are plenty of other people. Once that comes about and once media fragments are adopted, linking to or embedding a portion of a video will be as easy as using the correct fragment on your URL thanks to the Media Fragments WG who has been hard at work since the last time I looked at fragments.

However, until that work is embraced by browsers, embedding portions of videos will continue to require work specific to the site from which you are embedding the video. On the YouTube blog they wrote about how to "link to the best parts in your videos", using a fragment syntax like '#t=1m15s' to start playback of the associated video at 1 minute and 15 seconds. Of course if you want to embed part of a Hulu video it will be different. Although I haven't found an authoritative source describing the URL syntax to use, you can follow Hulu's video guide on linking to part of a video and note how the URL changes as you adjust the slider on the time-line. It looks like their syntax for linking to a Hulu page is to add '?c=[start time in seconds](:[end time in seconds])' with the colon and end time optional in order to link to a portion of a video. And the syntax for embedding appears to be "http://www.hulu.com/embed/.../[start time in seconds](/[end time in seconds])" again with the end time optional.

For more sites, check out the Media Fragments WG's list of existing applications' proprietary fragmenting schemes.

Mostly Moved Into New House

The weekend before the previous, Sarah and I moved our belongings into the new house and spent a lot of time packing and unpacking, and now we're officially living there (interested Facebook friends can find my new address or just ask me). The Saturday of the previous weekend Sarah's family came over for a half house warming and half Sarah's birthday celebration which was fun and served to force us to do more unpacking and forced me to take trips to Home Depot, Bed Bath and Beyond, etc. On Sunday, Sarah and I went out to her favorite restaurant and she opened her gifts that I had to hide to keep her from opening before her birthday. Happy Birthday Sarah!

While at Home Depot I had trouble finding what I was actually looking for, but I did find everything I needed to terminate the Cat5e cables that are wired in the house. Each room has a wall plate with two RJ45 sockets, both sockets wired to Cat5e cable. One of the cables per plate was already hooked up to a standard phone service punchdown board and the other cables per plate were all hanging unterminated next to the punchdown board. So now I've terminated them all with RJ45 connectors and hooked them up to my hub, wireless router, cable modem, etc. I had the same sort of fun setting all that up as I did playing with model train sets as a child. Hopefully no therapy will be required to figure out why that is.

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.
