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.

Irritatingly out of line with what their commercials say, in my area Comcast, under the covers of the national broadcast digital switch, is sneaking in their own switch to digital, moving channels above 30 to their own digital format. Previously, I had Windows 7 Media Center running on a PC with a Hauppauge PVR500 which can decode two television signals at once setup to record shows I like. The XBox 360 works great as a Media Center client letting me easily watch the recorded shows over my home network on my normal TV.

Unfortunately with Comcast's change, now one needs a cable box or a Comcast digital to analog converter in order to view their signal, but Comcast is offering up to two free converters for those who'd like them. The second of my two free converters I hooked up to the Media Center PC and I got the IR Blaster that came with my Hauppauge out of the garage. I plugged in the USB IR Blaster to my PC, connected one of the IR transmitters to the 1st port on the IR Blaster, and sat the IR transmitter next to the converter's IR receiver. I went through the Media Center TV setup again and happily it was able to figure out how to correctly change the channel on the converter. So I can record now, however:

1. I can only record one thing at a time now
2. Changing the channel is slow taking many seconds (no flipping through channels for me)
3. The Hauppauge card can't know if the channel change worked. So if it tries to change to HBO (I get it for free with one of the Comcast packages) which is encrypted and the converted won't show, the channel doesn't change but the PC doesn't know it and ends up recording some other channel.

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.

My parents visited this past weekend, met Sarah's parents, saw our house, and met our bunny. On Friday we went to BluWater in Kirkland which was pretty busy and the service was slower and slightly worse than we usually find. Saturday my parents helped us with our yard quite a bit and for dinner we went to the Icon Grill with Sarah's parents. I had forgotten how much I enjoy the food at the Icon Grill - I had the very tasty meat loaf. Dinner went well and afterward we stopped at the Three Lions pub in Redmond. On all previous occasions I had tried to go in there the place was packed for a soccer game. This night however there was a man with a guitar, singing and it wasn't nearly as packed. I also found that near the bathrooms on the wall is what looks to be James Bond's jetpack.

On Sunday we went out to see Jeannie and Carl and see the renovations to Jeannie's place. We met up with them at the Fremont Market to which I hadn't been previously, and had a look around there before going back to Jeannie's to see the lovely work they'd done to her place. For dinner my parents took us out to the Melting Pot for my approaching birthday. It was fun having my parents up and I look forward to the next time they're here.

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".

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.

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.

I've redone my blog's layout to remind myself how terrible CSS is -- err I mean to play with the more advanced features of CSS 2.1 which are all now available in IE8. As part of the new layout I've included my Delicious links by default but at a smaller size and I've replaced the navigation list options with Technical, Personal and Everything as I've heard from folks that that would actually be useful. Besides the layout I've also updated the back-end, switching from my handmade PHP+XSLT+RSS/Atom monster to a slightly less horrible PHP+DB solution. As a result everything should be much much faster including search which, incidentally, is so much easier to implement outside of XSLT.

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!

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.

I've hooked up the printer/scanner to the Media Center PC since I leave that on all the time anyway so we can have a networked printer. I wanted to hook up the scanner in a somewhat similar fashion but I didn't want to install HP's software (other than the drivers of course). So I've written my own script for scanning in PowerShell that does the following:

1. Scans using the Windows Image Acquisition APIs via COM
2. Runs OCR on the image using Microsoft Office Document Imaging via COM (which may already be on your PC if you have Office installed)
3. Converts the image to JPEG using .NET Image APIs
4. Stores the OCR text into the EXIF comment field using .NET Image APIs (which means Windows Search can index the image by the text in the image)
5. Moves the image to the public share

Here's the actual code from my scan.ps1 file:

param([Switch] $ShowProgress, [switch] $OpenCompletedResult)

$filePathTemplate = "C:\users\public\pictures\scanned\scan {0} {1}.{2}";
$time = get-date -uformat "%Y-%m-%d";

[void]([reflection.assembly]::loadfile( "C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll"))

$deviceManager = new-object -ComObject WIA.DeviceManager
$device = $deviceManager.DeviceInfos.Item(1).Connect();

foreach ($item in $device.Items) {
	$fileIdx = 0;
	while (test-path ($filePathTemplate -f $time,$fileIdx,"*")) {
		[void](  $fileIdx);
	}

	if ($ShowProgress) { "Scanning..." }

	$image = $item.Transfer();
	$fileName = ($filePathTemplate -f $time,$fileIdx,$image.FileExtension);
	$image.SaveFile($fileName);
	clear-variable image

	if ($ShowProgress) { "Running OCR..." }

	$modiDocument = new-object -comobject modi.document;
	$modiDocument.Create($fileName);
	$modiDocument.OCR();
	if ($modiDocument.Images.Count -gt 0) {
		$ocrText = $modiDocument.Images.Item(0).Layout.Text.ToString().Trim();
		$modiDocument.Close();
		clear-variable modiDocument

		if (!($ocrText.Equals(""))) {
			$fileAsImage = New-Object -TypeName system.drawing.bitmap -ArgumentList $fileName
			if (!($fileName.EndsWith(".jpg") -or $fileName.EndsWith(".jpeg"))) {
				if ($ShowProgress) { "Converting to JPEG..." }

				$newFileName = ($filePathTemplate -f $time,$fileIdx,"jpg");
				$fileAsImage.Save($newFileName, [System.Drawing.Imaging.ImageFormat]::Jpeg);
				$fileAsImage.Dispose();
				del $fileName;

				$fileAsImage = New-Object -TypeName system.drawing.bitmap -ArgumentList $newFileName 
				$fileName = $newFileName
			}

			if ($ShowProgress) { "Saving OCR Text..." }

			$property = $fileAsImage.PropertyItems[0];
			$property.Id = 40092;
			$property.Type = 1;
			$property.Value = [system.text.encoding]::Unicode.GetBytes($ocrText);
			$property.Len = $property.Value.Count;
			$fileAsImage.SetPropertyItem($property);
			$fileAsImage.Save(($fileName   ".new"));
			$fileAsImage.Dispose();
			del $fileName;
			ren ($fileName   ".new") $fileName
		}
	}
	else {
		$modiDocument.Close();
		clear-variable modiDocument
	}

	if ($ShowProgress) { "Done." }

	if ($OpenCompletedResult) {
		. $fileName;
	}
	else {
		$result = dir $fileName;
		$result | add-member -membertype noteproperty -name OCRText -value $ocrText
		$result
	}
}

I ran into a few issues:

• MODI doesn't seem to be in the Office 2010 Technical Preview I installed first. Installing Office 2007 fixed that.
• The MODI.Document class, at least via PowerShell, can't be instantiated in a 64bit environment. To run the script on my 64bit OS I had to start powershell from the 32bit cmd.exe (C:\windows\syswow64\cmd.exe).
• I was planning to hook up my script to the scanner's 'Scan' button, but HP didn't get the button working for their Vista driver. Their workaround is "don't do that!".
• You must call Image.Dispose() to get .NET to release its reference to the corresponding image file.
• In trying to figure out how to store the text in the files comment, I ran into a dead-end trying to find the corresponding setter for GetDetailsOf which folks like James O'Neil use in PowerShell for interesting ends.

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.

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.

I've made an OpenSearchDescriptionToHTML XSLT that given an OpenSearch description file produces HTML that describes that file, lets you install it, or search with it. For example, here's a Google OpenSearch description that uses my OpenSearchDescriptionToHTML XSLT.

I had just created an OpenSearch description for WolframAlpha at work and was going about the process of adding another install link to my search provider page so that I could install it. Thinking about it, I realized I could apply an XSLT to the OpenSearch description XML to produce the HTML automatically so I wouldn't have to modify additional documents everytime I create and want to install a new OpenSearch description. While I was in there writing the XSLT I figure why not let the user try out searching with the OpenSearch description file too. And lastly I made the XSLT apply to itself to produce HTML describing its own usage.

Incidentally, I added WolframAlpha at work to replace my FileInfo search provider for the purposes of searching for information about particular Unicode characters. For instance, look at WolframAlpha's lovely output for this search for "Bopomofo zh".

• 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.

I like the idea of QR codes, encoding URLs and placing them on real world objects, but the QR codes themselves are kind of ugly. To make them less obvious I thought I could spray QR codes on to an object with an infrared reflective paint and shine infrared light on the QR codes, since most cameras, for instance the camera in my G1 phone, pick up infrared that our eyes do not.

In my search for infrared paint I've found a seller of IR ink (via programming forum) and an Infrared Paint Recipe (via IR FAQ).

In looking for this paint I've found that it comes up a lot in relation to the military for things like paint markers that are visible at night with proper equipment, and paint that absorbs IR light to make vehicles less obvious to night vision goggles. Even though the first reflects infrared light and the second absorbs it websites end up refering to both as infrared paint which made it difficult to search.

Additionally I found links to some other geeky infrared projects:

• Infrared goggles that block out all light except for the edge of infrared light that humans can perceive.
• A project to make infrared patterns and paint to screw with tourist video/photos.

Checking out at a grocery store to which I rarely go, the cashier asks me if I want an Albertson's card. I respond sure and she hands me the form on which I give up my personal information. I ask if I need to fill this out now, and she says yeah and it will only take two minutes, which surprised me because at QFC they just hand me a new card and send me on my way. I fill in my phone number as the first ten digits of pi so I don't have to worry about getting phone calls but its something I can remember next time I'm there and don't bring the card.

I turn to leave and the cashier asks me is that a '759' or '159' in my phone number. I stop for a second because I only know the digits as a sequence from the start and pause long enough reciting it in my head that its clear its not my phone number. And she calls me out on it: "Is that your real phone number?" I sigh, "No, does it have to be? Are you going to call me?" "Yeah," she says, "I'll call you." (ha ha) "Well I'll try entering this number," she says doubting the computer will accept the fake phone number. "On the number's already registered," she says, "So you already had a card." "No," says the manager who had walked up during for this exchange, "It means someone else used that same number." So the moral of the story is, try your fake phone number before trying to use it to get a new card.

In honor of Google Chrome's recent v2 release and because I read they don't make too big a deal about version numbers, I thought to create a graph of browser major version numbers over time.

Yeah that's not too useful of a graph. I got the release dates from Wikipedia of course.

As you can see from the graph, Netscape and Opera are leading all other browsers in terms of major version number. The other browsers really need to get on that.

Sarah and I have a new place in Redmond and we'll be moving there in a few weeks. Exciting! Incidentally, when researching the place on the Internet I found that the nearby park used to be a radar site for the Project Nike missile system in the fifties. Fun!

I watched the new Star Trek movie Thursday morning, along with many others who work on Windows. Microsoft rented out a theater and played the movie on all screens. I greatly enjoyed the movie!

Spoilers follow... I'm obviously not the biggest Star Trek nerd (or at least TOS nerd) since I didn't even pick up on the fact that Kirk's dad being dead was a discrepancy from the TV series. I only figured out the alternate time-line stuff when they killed most of the Vulcans. I was just surprised they didn't set right what once went wrong by the end of the movie with some more time travel magic to bring back Vulcan. On that note, I'm pretty sure the Spock-Spock conversation at the end, is Nimoy Spock sending Sylar Spock off to school so that Nimoy Spock can get freaky repopulating the Vulcan race. Although at first after his 'two places at once' comment I thought he was saying... something else. Also, was the main evil guy a random miner turned psycho? And his crazy looking spaceship that destroys the Federation fleet was just a mining vessel from the future? Once they invent time travel anybody can get drunk, go back in time, and conquer Earth.
