Irritatingly, my G1 won't show me PDFs so I've made the Google Docs PDF viewer which will load PDFs on the web up in Google Docs. Google Docs has the useful ability to display PDFs in web browsers without any Adobe software and works (mostly) on Android.
This was very easy to put together as an Android activity. First its necessary to register the application as handling PDFs from the web. This is done via the intent-filter declaration in the manifest:
intent-filter
action android:name="android.intent.action.VIEW"/
data android:scheme="http" android:mimeType="application/pdf"/
category android:name="android.intent.category.DEFAULT"/
category android:name="android.intent.category.BROWSABLE"/
/intent-filterSecond, the activity opens up the browser to Google Docs pointing to the PDF.
Intent intent = new Intent();
intent.setAction(getIntent().getAction());
intent.setData(Uri.parse(
"http://docs.google.com/gview?embedded=true&url=" +
percentEncodeForQuery(getIntent().getData().toString())));
startActivity(intent);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.
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:
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 01Converting 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: 2009-08-28:10:18:00.000When 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.
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.
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:
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.
On the topic of made up words: I get made up words for made up things, but there's already a name for cell-phone in English: its "cell-phone". The narrator notes that the book has been translated into English so I guess I'll blame the fictional translator. Anyway, I wasn't bothered by the made up words nearly as much as some folk. Its a good thing I'm long out of college because I can easily imagine confusing the names of actual concepts and people with those from the book, like Hemn space for Hamming distance. Towards the beginning, the description of slines and the post-post-apocalyptic setting reminded me briefly of Idiocracy.
Recently, I've been reading everything of Charles Stross that I can, including about a month ago, The Jennifer Morgue from the surprisingly awesome amalgamation genre of spy thriller and Lovecraft horror. Its the second in a series set in a universe in which magic exists as a form of mathematics and follows Bob Howard programmer/hacker, cube dweller, and begrudging spy who works for a government agency tasked to suppress this knowledge and protect the world from its use. For a taste, try a short story from the series that's freely available on Tor's website, Down on the Farm.
Coincidentally, both Anathem and the Bob Howard series take an interest in the world of Platonic ideals. In the case of Anathem (without spoiling anything) the universe of Platonic ideals, under a different name of course, is debated by the characters to be either just a concept or an actual separate universe and later becomes the underpinning of major events in the book. In the Bob Howard series, magic is applied mathematics that through particular proofs or computations awakens/disturbs/provokes unnamed horrors in the universe of Platonic ideals to produce some desired effect in Bob's universe.
Microsoft isn't completely shielded from our economies issues but I still have a job and
still get free soda. While that's all still the case, I decided to test Sarah's claimed ability to differentiate between Pepsi, Coke, and their diet counterparts by taste alone. I poured the four
sodas into marked cups and Sarah and I each took two runs through the cups with the following guesses.
| Drink | Sarah | Dave | ||
|---|---|---|---|---|
| Guess 1 | Guess 2 | Guess 1 | Guess 2 | |
| Coke | Coke | Coke | Pepsi | Diet Pepsi |
| Diet Coke | Diet Coke | Diet Pepsi | Diet Coke | Diet Coke |
| Pepsi | Pepsi | Pepsi | Coke | Coke |
| Diet Pepsi | Diet Pepsi | Diet Coke | Diet Pepsi | Pepsi |
| Total (out of 8) | 6 | 3 | ||
As you can see from the results, Sarah's claimed ability to identify Coke and Pepsi by taste is confirmed. The first run through she got completely correct and on the second run only mistook Diet Pepsi for Diet Coke. Her excuse for the error on the second run was a tainted palate from the first run. I on the other hand was mostly incorrect. Surprisingly though my incorrect answers were mostly consistent between run one and two. For instance I thought Pepsi was Coke in both runs.
