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:
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:
I've made a QR Encode accelerator around Google Chart's QR code generator. QR codes are 2D bar-codes that can store (among other things) URLs and have good support on mobile
phones. The accelerator I've written lets you generate a QR code for a selected link and view it in the preview window. In combination with the ZXing
bar-code scanner app for my Android cellphone, its easy for me to right click on a link in IE8 on my desktop PC, hover over the QR Encode accelerator to have the link's associated QR code
displayed, and then with my phone read that QR code to open my phone's browser to the URL contained inside. Its much easier to browse around in the comfort of my desktop and only send particular
URLs to my cellphone as necessary.
A while ago I promised to say how an xsltproc Meddler script would be useful and the general answer is
its useful for hooking up a client application that wants data from the web in a particular XML format and the data is available on the web but in another XML format. The specific case for this
post is a Flickr Search service that includes IE8 Visual Search Suggestions. IE8
wants the Visual Search Suggestions XML format and Flickr gives out search data in their Flickr web API XML format.
So I wrote an XSLT to convert from Flickr Search XML to Visual Suggestions XML and used my xsltproc Meddler script to actually apply this xslt.
After getting this all working I've placed the result in two places: (1) I've updated the xsltproc Meddler script to include this XSLT and an XML file to install it as a search provider - although you'll need to edit the XML to include your own Flickr API key. (2) I've created a service for this so you can just install the Flickr search provider if you're interested in having the functionality and don't care about the implementation. Additionally, to the search provider I've added accelerator preview support to show the Flickr slideshow which I think looks snazzy.
Doing a quick search for this it looks like there's at least one other such implementation, but mine has the distinction of being done through XSLT which I provide, updated XML namespaces to work with the released version of IE8, and I made it so you know its good.
I finally replaced my old regular cell-phone which was literally being held together by a rubber band with a fancy new G1, my first Internet accessible phone.
I had to call the T-Mobile support line to get data added to my plan and the person helping me was disconcertingly friendly. She asked about my weekend plans and so I felt compelled to ask her the same. Her plans involved replacing her video card so she could get back to World of Warcraft and do I enjoy computer gaming? I couldn't tell if she was genuine or if she was signing me up for magazines.
I was with Sarah in her new car, trying out the phone's GPS functionality via Google Maps while she drove. I switched to Street View and happened to find my car. It was a weird feeling, kind of like those Google conspiracy videos.
The phone runs Google's open source OS and I really enjoy the application API. Its all in Java and URIs and mime-types are sort of basics. Rather than invoking the builtin item picker control directly you invoke an 'intent' specifying the URI of your list of items, a mime-type describing the type of items in the list, and an action 'PICK' and whatever is registered as the picker on the system pops up and lets the user pick from that list. The same goes if you want to 'EDIT' an image, or 'VIEW' an mp3.
I wanted to replace the Google search box gadget that appears on the home screen with my own search box widget that uses OpenSearch descriptors but apparently in the current API you can't make home screen gadgets without changing parts of the OS. My other desired application is something to replace this GPS photo tracker device by recording my location to a file and an additional program on my computer to apply those locations to photos.
I recently finished Braid, the Xbox Live game, and a comparison with Portal is helpful. From a screen shot Braid
looks like a normal 2D platformer, but that's like looking at a screen shot of Portal and saying its a first person shooter. While the scaffolding of the game-play may sort of fall into that
category, the games are actually about exploring the character's ability and solving puzzles. In Portal the ability is bending space and in Braid its bending time. However, whereas in Portal there
is one space bending mechanism, the portal gun, Braid's protagonist explores several different time bending techniques including, most prominently, reversing time, but also time dilation, multiple
time-lines, and other odd things.
Similar to the difference in game-play, while Portal has a strict simplicity to its visual style, Braid is much more ornate, like you're playing in an oil painting. Without seeing video of the game, or playing the demo (which is available for free on Xbox Live) its difficult to convey, but it is quite lovely and the animation adds quite a bit. Both games too are rather short leaving you just a bit hungry for more and have an interesting plot and an ending that I'd hate to spoil although Braid replaces Portal's humor with melancholy. If you enjoyed Portal and Twelve Monkeys then I'd recommend Braid.
The weekend before last I saw Dark Knight with some friends from work and then we all ate at Z'Tejas after. Like everyone has said and as the name implies Dark Knight is... dark. Dark Knight was a little over the top at times as compared to Batman Begins but I really enjoyed it. Two times during the movie I thought it had ended but I was wrong. The Joker is both frightening (Cringe inducing line "Wanna know how I got these scars?") and humorous ("Where is Harvey Dent? ... You know where Harvey is? You know who he is?", as well as the pencil magic trick). I can certainly recommend it to anyone who enjoyed Batman Begins. The previews included Burn After Reading a new Coen Brother's comedy that I look forward to, and Quantum of Solace which hopefully does the same thing Dark Knight has, keep up the new direction on the refreshed franchise.
This past
weekend Sarah and I went to a Mariners baseball game. I think this is the first MLB baseball game I've seen in person. Sarah's company gave out tickets for the game and the use of a suite. Its a
room half way up the stadium with comfortable chairs, a mini-fridge built-in to the marble counter-topped center table, and a big flat screen television with the game on it. I suppose that's in
case you don't want to turn to the right and sit at the window, or walk out onto the balcony which features three rows of comfy chairs overlooking the field. Anyway there was free food and drinks
and I met some of the people Sarah works with.
I ordered a ThinkGeek Bluetooth Retro Handset to use at home. When I come home I plug my phone in to charge in my room, but then I can't hear it ring
elsewhere in the hosue. The idea was to take this handset which wirelessly connects to cellphones via bluetooth and place it in another part of the house so that I can tell I'm getting an incoming
call. The only issue I have with that setup is that it ringing isn't any louder than conversations held over the phone, that is, the ringing is a little quiet.
The handset pairs with cellphones in the same manner as any other handset over bluetooth. It has an internal rechargeable battery which is charged via a standard USB port built into the base of the handset and it comes with a USB cable. Next to the USB port is the only button on the phone which is pressed to answer a call, hang up a call, or begin voice dial, held down to turn the handset on and off, and held down longer to begin pairing with a cellphone. There's a blue LED in one of the holes in the microphone portion of the phone which blinks to indicate if its on or trying to pair. Transitioning between on, off, and pairing produces a cute sound and a change to the LED.
Overal I'm pleased with its simplicity and use of common parts although I wish there was a way to adjust the volume of the ring.
Internet Explorer 8 Beta 1 is available now. I can finally talk about some of the stuff I've been working on for the past year or so: activities. Activities let you select a document, some text on a document, or a link to a document and run that selection through a web service. For example, you could select a word on a webpage and look it up in Wikipedia, select an address and map it on Yahoo Maps, select a webpage and translate it into English with Windows Live Translator, or select a link and add it to Digg.
IE8 comes installed with some activities based on Microsoft web services but there's a page you can go to to
install other activities. However, that page is missing some of my favorites that I use all the time, like del.icio.us.
Accordingly, I've put together a page of the activities I use. MSDN has all the info on creating Activities.
Activities are very similar to other existing features in other browsers including the ability to add context menu items to IE. There's two important differences which make activities better. Activities have a preview window that pops out when you hover over an activity, which is useful to get in place information easily provided by developers. The other is that the interface is explicit and takes after HTML FORMs and OpenSearch descriptions. Because the interface is explicitly described in XML (unlike the context menu additions described above which run arbitrary script) we have the ability to use activities in places other than on a webpage in the future. And because activity definitions are similar to HTML FORMs, if your webservice has an HTML FORM describing it you can easily create an activity.
I signed up for the pre-release beta and purchased a Chumby last year. Chumby looks like a cousin to a GPS
unit. Its similar in size with a touch screen, but has WiFi, accelerometers, and is pillow like on the sides that aren't a screen. In practice its like an Internet alarm clock that shows you photos
and videos off the Web. Its hackable in that Chumby Industries tells you about the various ways to run your own stuff on the Chumby, modifying the boot sequence (it runs Linux), turning on sshd,
etc, etc. The Chumby forum too has lots of info from folks who have found interesting hacks for the device.
When you turn on the Chumby it downloads and runs the latest version of the Chumby software which lets you set alarms, play music, and display Flash widgets. The Chumby website lets anyone upload their own Flash widgets to share with the community. I tried my hand at creating one using Adobe's free Flash creation SDK but I don't know Flash and didn't have the patience to learn.
Currently my Chumby is set to wake me up at 8am on weekdays with music from ShoutCast and then displays traffic and weather. At 10am everyday it switches to showing me a slide-show of LolCats. At 11pm it switches to night mode where it displays the time in dark grey text on a black background at a reduced light level so as not to disturb me while I sleep.
I like the Chumby but I have two complaints. The first is that it forces me to learn flash in order to create anything cool rather than having a built-in Web browser or depending on a more Web friendly technology. The second complaint is about its name. At first I thought the name was stupid in a kind of silly way, but now that I'm used to the name it sounds vaguely dirty.
