Memorial Service for Google Wave at Google's Tokyo Office

Yusuke Kawasaki — 2010-08-24T12:39:36.221+09:00

Tokyo, Japan - Japanese developers have held the memorial service for Google Wave somberly at Google's Tokyo office. Grieving attendees held a condolence telegram and the deceased's deadee.

Google Japan respectfully provided their new Roppongi office as a venue for the memorial service and made an arrangement to style the wallpapers in monotone.

The chief mourner, Yasushi Ando (@technohippy), pensively signed his new Google Wave introductory book which is just published this week.

A Googler behaved just positively in her video message which filled our eyes with waves of tears.

Sorry, but too many jokes covered around whole of the memorial service, in fact! :)

We all attendees enjoyed the convivial event with beers, wines and laughs.

The three types of Wave T-shirts above are now rarely acquirable though.

Thank you, Google Wave, we will never forget you on the cloud.

What is the coming next service listed on Google Graveyard?

Shibuya.js won the prize at LT championship, LLTiger

Yusuke Kawasaki — 2010-08-22T23:36:20.465+09:00

July 31st, the Japan UNIX Society hosted the LL Tiger conference as a series of their annual Lightweight Language developer events. Eight teams competed at the lightening talks tournament championship held in the conference. Our team of Shibuya.js, Tokyo-based JavaScript developers group, did it to win the first prize at the hard knockout competition!

Preliminary Round

Just a day before the championship, we Shibuya.js members had an tech meetup event titled Shibuya.js beyond HTML5 as the preliminary round to pick up the presenters.

(photo by @takesako)

At the pre-round, three speakers, @gyuque, @yukoba and me was selected.

The First Round - @gyuque

On the following day, our presenter for the first round was @gyuque. He gave a talk about a software modem implemented by JavaScript. His JavaScript FSK modulator generates sound waves for data payloads. Then it plays generated .wav data encoded in base64 via data: scheme through HTML5's <audio> element.

See also @gyuque's slides on Slideshare.

The Second Round - @kawanet

At the semi-final match, I @kawanet gave a talk about 3D JavaScript. The talk was enhanced since I gave the former talk at OSDC.TW 2010 in Taipei.

See also my slides.
* Right cursor or mouse click - Proceed to the next
* Left cursor - Back to the previous
* 0 key - Return to the first slide
* 3 key - Toggle 3D mode and 2D mode
* Use red-blue glasses to see anaglyph 3D.

At the intermission after the first round, we decided to add an additional demo for the second round. Our JavaScript guru @gyuque wrote the real-time 3D demo below within just 30 minutes.

The Final Round - @yukoba vs. @takesako

At the final, our last speaker @yukoba fighted against @takesako from the Project-D Team. He is a tough rival as he is also a member of our Shibuya.js group. This means the last match is blue-on-blue.

Takesako gave a talk about an 8086 assembler implemented by JavaScript. The assembler is not normal but generates bytes covered with many ASCII arts of smileys like [^_^].

At Yukoba's turn, he gave a talk about a JVM including MIDP implemented by JavaScript. He compiles .class binary files of Java to .js source code files of JavaScript. The compiled code runs on his JS-based JVM which works on HTML5 web browsers including Google Chrome and WebKit. It means mobile phone applications for MIDP devices would run on iPhone and Android phones without any codes changed. I'm sure that his system has incredible potential for mobile game market.

See also @takesako's slides and @yukoba's video from 07:40 on Ustream.

I won an iPad!

Our team Shibuya.js won the championship at last. As the bonus prize, I got an iPad. Thanks!

Invitations for other tournaments are welcomed. ; )

#Flickr is still a-bombing on Organizr. (Workaround patch added!)

Yusuke Kawasaki — 2010-08-08T15:58:49.010+09:00

I'm sorry but this post is not in a political campaign. I just want to tell that, today, I feel really sad with the great photo sharing service of flickr.

I'm an individual flickr lover and have an Pro account of it. You can also find my bookmarklet for flickr.

Two weeks ago, I've posted a comment on the Flickr Ideas discussion group. The thread titled "Drop a A-bomb on flickr!?!" has existed since 2007.

In the Flickr Organizr, at removing operations of photos, it shows a bombing animation as below:
I feel uncomfortable whenever I see it. It just evokes the days in Hiroshima and Nagasaki. I thought, however, it would be an imagining thing as I am a Japanese.

Last month, I found I was not wrong. The bomb was not just a conventional bomb but was designed as an atomic bomb. The animation GIF file has name of nuke.gif. This unacceptable discovery makes me posting the comment.

Two weeks have passed. Today, August 6, is the 65th anniversary of the bombing on Hiroshima. Flickr is still a-bombing on Organizr. I never do the operation of removing photos on Organizr in order not to see the nuke.

I won't think the bombing is a part of spirits of Yahoo.

See also:
U.S. Envoy Attends Hiroshima Event - New York Times
Atomic bombings of Hiroshima and Nagasaki - Wikipedia
I don't know U.S. schools teach the terrible horror side of the a-bomb underneath the mushroom-shaped cloud.

Note that Yahoo Japan Corporation does NOT provide the flickr service here in Japan market.

(Updated / August 8)
I wrote a bookmarklet to patch the Flickr's Organizr.

When a photo is removed from batch area, the patched Organizr will just fade it out instead of showing the unwelcome a-bomb animation of nuke.gif.

[Organizr Patch]

Save above link (bookmarklet) to your bookmark toolbar. And click it just once after you open the Organizr.

The source code is below.

reorder_drag.prototype.frame_explode=function(){
var e=this.getDragEl();
var a=new YAHOO.util.Anim(e,{opacity:{from:1,to:0}},0.5,YAHOO.util.Easing.easeOut);
a.animate();
var f=function(){
e.style.opacity='';
e.style.display='none';
};
reorder_drag.explode_tim=setTimeout(f,1800);
}

YUI library helps this. Yahoo rocks. :)

The Korean Alphabet, iPhone app built by Flash

Yusuke Kawasaki — 2010-06-01T14:52:29.342+09:00

I've shipped the Korean Alphabet which is a paid iPhone application to study Hangul. It's now available on the iTunes Store. This was build by ActionScript with the Packagers for iPhone® under Adobe's Flash CS5 pre-release beta program.

This app represents Hangul with the Roman (Latin) alphabet to help you to read (say) Korean phrases. Enjoy this when you're traveling in Korea, studying Korean, watching Korean TV dramas, etc.

Hangul is the native phonemic character of Korean language. The system is also called as Korean romanization or latinization. In 2006, I've also released the web service version of this for PC web browsers. Note that I'm a native of Japanese language however.

Meet again at YAPC::Asia 2010 Tokyo in October

Yusuke Kawasaki — 2010-05-03T16:48:55.441+09:00

I was back to Japan from Taiwan. It's my third time to attend the OSDC.TW. I must say thank you for the Taiwanese hackers to warmly welcome us, Shibuya.pm, to have our first tech talk session abroad. More than a few of us, including me, must attend the OSDC.TW again next year.

By the way, some people there asked me when the YAPC::Asia Tokyo would be held. It's not officially announced in English.

@941-san who is the events organizing lead in the JPA, Japan Perl Association, has announced the brief schedule for the YAPC::Asia 2010 Tokyo as following:

May - the first splash website opened
July - CFP started
August - registration started
October - curtain-up!

Details about the venue and exact date don't seem fixed yet. They are planning to hold it at somewhere in/near Tokyo at October 14th-16th as their current plan noted only in Japanese. After fixed by the JPA, the details would be announced also in English as in the past years.

I hope you all friends could meet here again at Japan's beautiful season of Autumn.

3D Bookmarklet - Enjoy 3D world on the Web by CSS3

Yusuke Kawasaki — 2010-05-03T15:42:54.678+09:00

The 3D Bookmarklet is a bookmarklet which allows you to dive into the 3D-world on the Web. CSS3 capable browser is needed. Firefox 3.5 and Chrome 5 is tested.

* Get the 3D bookmarklet

Drag the link [3D] onto your browser's bookmark toolbar, etc.

* Try now on this page

Every 2D websites will come into 3D with this. You need to have a red/blue (anaglyph) 3D glasses by yourself. The CSS3 standard allows iPhone and iPad to run this. Enjoy 3D everywhere!

Gugod and I have corroborated to the code snippet as a result from the OSDC.TW Hackathon.

How this works

This sets all text's CSS color property to red, and also sets text-shadow property to blue on right. Gugod gave me an idea to hack to draw with alpha channel using rgba(). Each 3D layer, depth, is depend on sort of its element and font size. Firefox seems not to allow !important within element's style attribute. Chrome however does. Only texts are made into 3D. Images are not yet at this version.

PS.

Hualien is a city located at East Coast of Taiwan. You may know everybody in town there wears 3D glasses to enjoy 3D world. :)

CSS3 Powered 3D Presentation - OSDC.TW 2010

Yusuke Kawasaki — 2010-04-28T18:39:49.731+09:00

You're still running the classical 2D-era presentation tools, e.g. PowerPoint or Keynote? The 3D-era has just come since OSDC.TW 2010.

I gave Something Xiaolongbao talk at the most major open source developers conference in Taiwan.

This year's main theme in my talk is the 3D presentation using CSS3 techs. I wrote an HTML5/JavaScript-based presentation tool for the talk.

Usage:
Next Slide - Mouse Click, Space Key or Right Arrow Key
Prev Slide - Left Arrow key
First Slide - [0] Key
3D Mode Toggle - [3] Key

For 3D newbie, try [3] key to turn off 3D and fall back to 2D. :)

The slides are based on HTML5 / JavaScript / CSS3 and the cutting-edge 3D tech of "anaglyph." I've brought some red-blue 3D glasses for the conference from Japan.

At the OSDC.TW day 1 early morning, I wrote pptx2html53d.pl, a Perl script to convert from PowerPoint .pptx file to 3D HTML5 .html. I'll make it open later. Basically .pptx file is a ZIP file. It's pretty easy to parse .pptx using Archive::Zip and XML::TreePP Perl modules. pptx2html53d.pl generates a HTML5 source code.

At first, I also used SVG's feColorMatrix feature for 3D. It's however cancelled at this moment as not working well. And also Chrome 5 for Mac seems it could not run SVG's filter element. The slides above are updated as Gugod gave me nice advices around CSS3 usage of text-shadow.

Buy 3D glasses in town and enjoy 3D presentation now.

Shibuya Perl Mongers comes into Taipei! - OSDC.TW 2010

Yusuke Kawasaki — 2010-04-23T01:44:13.223+09:00

The Shibuya.pm comes in Taipei!
The Shibuya Perl Mongers is a community of Perl hackers based in Tokyo. The super hackers give technical talks away in the special sub-conference of the OSDC.TW 2010. You'll see the highest level in techniques and the lowest level in depth of Perl with us.
Don't miss this and enjoy.

Speakers

竹迫良範 (Yoshinori Takesako) @takesako - Polyglot Programming
石垣憲一 (Kenichi Ishigaki) @charsbar - Perl for a translator
藤吾郎 (Goro Fuji) @__gfx__ - Xslate - A high performance template engine
川崎有亮 (Yusuke Kawasaki) @kawanet - Something Xiaolongbao
檀上伸郎 (Nobuo Danjou) @lopnor - Net::Google::Spreadsheet
宮川達彦 (Tatsuhiko Miyagawa) @miyagawa - cpanminus
松野徳大 (Tokuhiro Matsuno) @tokuhirom - Perl5.12's new feature - PL_keyword_plugin *hack*
大沢和宏 (Kazuhiro Osawa) @yappo - Ajax application testing

This is the 13th tech talk conference by Shibuya.pm and the first time abroad.
At the day of the hackathon soon after the last YAPC::Asia 2009 conference was over, we had a lot to talk about foreign conferences to attend. I'm really happy that it's come true.

What's Shibuya

Shibuya is a culture heart district of Tokyo. The word Shibuya (渋谷) literally means "Bitter Valley." Like Silicon Valley, many Web/IT companies have started up from Shibuya.

That is, Shibuya is just a symbol for us. There is a fact that we've never had a tech talk conference in Shibuya district though.

RubyConf Taiwan 2010

The next day of Shibuya.pm in Taipei, three Ruby hackers from Japan will also give talks in the same venue. RubyConf Taiwan 2010 is the first regional Ruby Conference in Taiwan. Arai-san, Kakutani-san and Takahashi-san will come to speak there.

At the Spring, eight Perl guys and three Ruby guys, from Japan, will attend the conferences in Taiwan. I'm sure that we could boost the stream of the kind of international exchanges between East Asian developer communities.

Last year

This is my third time to attend the OSDC.TW.

- JSAR (JavaScript Augmented Reality) at OSDC.TW 2009 Taipei
- OSDC.TW 2008 - DOM manipulation by Wiimote/Gainer over HTTP

I've given talks about JavaScript and Flash in addition to Perl.
For this year, I had a plan of a new topic, however, it's forced to be canceled due to a sudden change of a SDK license agreement this month. orz.
I need to write new slides until the time of my slot at Saturday.

KTween 1.0.1 Released - Simple & Fast Tween Engine for AS3

Yusuke Kawasaki — 2010-04-14T10:16:19.523+09:00

KTween is now as fast as the cool tween engine of the Eaze Tween. The Eaze has jQuery-like method chain interface. Philippe Elsass has pointed that his Eaze Tween is faster than KTween, soon after my last post.
Now, here comes KTween's turn:

Running on my MacBook Pro, Mac OS X 10.6.3, Core 2 Duo 2.26GHz, Flash Player 10.1 Release Candidate, Firefox plug-in, the bench shows the KTween is a teeny bit faster than the Eaze. However, I could say it's still in the range of error.

The bench runs with the engines below:
KTween - Version 1.0.1 Revision 79
BetweenAS3 - Revision 3765.
GTween - Version 2.01 (2009/12/11)
tweener - Revision 424
TweenNano – Version 1.03 (2010/04/03)
eaze-tween - Revision 74

I guess it'd be rare that a case tweens 4,000 particles though. :-)
KTween is an open source distributed under the MIT license.

Try KTween.

Download: KTween 1.0.1 (20100413)

* The original post written in Japanese is here

* Note that the benchmark result is depend on machine, OS, flash player version and revision etc. The BetweenAS3 becomes the fastest engine in the six above in a case for instance.

Simplified and Traditional Chinese Alphabet iPhone Application Shipped!

Yusuke Kawasaki — 2010-02-27T23:56:02.329+09:00

I'm happy to announce to releasing a couple of the Chinese Alphabet iPhone application. These are Chinese version of the Korean Alphabet I've released last week.

Simplified Chinese Alphabet

This tells how to read/pronounce Chinese characters used in the mainland China. You could read Chinese characters by Latin (Roman) alphabet notated.

Traditional Chinese Alphabet

This is the traditional, complex and old-styled, Chinese characters version which are used in Taiwan and Hong Kong.

Once I've got a taxi at Beijing, the driver could not understand the Great Wall I said. I hope the app would help such scenes.

iSWF - iPhone Appearance Simulator for Flash

Yusuke Kawasaki — 2010-02-27T23:21:33.649+09:00

The iSWF is an appearance simulator for iPhone applications developed by Flash. This helps you to develop iPhone app and take its screen capture on your Mac.

Get iSWF from Google Code:
http://code.google.com/p/kawanet/downloads/detail?name=iSWF-20100227.zip

1. Install iPhone SDK

At first, get and install the iPhone SDK from Apple:
http://developer.apple.com/iphone/

"iPhone SDK 3.1.3 with Xcode 3.1.4" for 10.5 (Leopard) users,
"iPhone SDK 3.1.3 with Xcode 3.2.1" for 10.6 (Snow Leopard) users.

After installing it, try to run iPhone Simulator located at:
/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications

Important note, as you know, iPhone's Safari could not run Flash.

2. Install AIR 2.0 Beta SDK

Install AIR 2.0 Beta SDK as the next.
Note skip this step when you're already using CS5.

http://labs.adobe.com/downloads/air2.html
Click "Download for Macintosh (TBZ2, 17.9 MB)".

Unzip air2_b2_sdk_mac_020210.tbz2 and change the folder name as "AIK2.0" and move the folder to "/Applications/Adobe Flash CS4" . Check black "adl" icon at
/Applications/Adobe Flash CS4/AIK2.0/bin

3. Publish .swf

Publish your MyApp.swf using your CS4.
Flash Player 10, 320px width, 480px height and any frame rate.

4. Get iSWF package

Get the iSWF package from Google Code:
http://code.google.com/p/kawanet/downloads/detail?name=iSWF-20100227.zip

Unzip the archive and move its contents to the folder of MyApp.swf. Then double click iSWF.command to run MyApp.swf. You would see the appearance simulator running as the first picture of the post.

Copy each three files of iSWF to any other your .swf project.

5. How it works?

The iSWF runs the most recent changed .swf file in the same folder. It's quite simple. See the iSWF.html. The iSWF uses the same appearance of Apple's iPhone Simulator. This means iSWF could not run on Windows which Apple doesn't care for.

6. ActionScript for iPhone

Flash application for iPhone is based on AIR technology. The iSWF, however, runs the app in the localTrusted sandbox. And also multi-touch, GPS, File class and iPhone's native keyboard are not avaible with iSWF. Wait CS5 released for you to start such developments.

KTween - the world's fastest simple tween engine for AS3

Yusuke Kawasaki — 2010-02-16T00:02:06.695+09:00

I've released the quite new, simple, lightweight tween engine for ActionScript 3.0. This would come to be the best choice for developing mobile contents targeting smart phones. Currently, at the moment of the mid-February, the KTween is the world's fastest tween engine for the lightweight AS3 web development scene. This open source product is available on the Google Code under the MIT license.

18.9% faster than the Tweener

The benchmark tweens 2,000 objects in six seconds. I run it three times for each tween engines to take the average frame-rate below.
I run this on the standalone Flash Player 10.0.22.87, Core 2 Duo 2.26 GHz, MacBook Pro Unibody. The screen capture is:
Larger number of fps means faster. Source code of this is here.

Engine	FPS
KTween	27.19 fps
BetweenAS3	26.77 fps
TweenNano	26.70 fps
GTween	26.38 fps
Tweener	22.87 fps

Note that the KTween engine is one of the most reasonable alternative for the time-honored engine of the Tweener especially for the applications targeting a mobile device which is not allowed to run Adobe's Flash Player, as needing AS3's type declaration will soon come the must thing in case of compiling the .swf (ABC) to the native binary (ex. armv6/7).

SYNOPSIS

import net.kawa.tween.KTween;
import net.kawa.tween.easing.*;

public function run():void {
KTween.to(mySprite, 2, {alpha: 0.0}, Linear.easeOut, callback);
KTween.from(mySprite, 3, {x:320, y;480}, Quad.easeOut).round = true;
}

The syntax looks like the TweenMax series. This means the users could easily transfer to the new engine.

FEATURES

Free under the MIT license. Original. written from scratch.
ActionScript 3.0. Flash 9/10 and later.
Simple. Shorter source code. Less file bytes.
Much faster than Tweener and GTween. Bit faster than TweenNano and BetweenAS3.
AS3 type declaration checking available for the options of KTween

I like the code auto completion with the AS3's type declarations. This makes the developing more confortable.

See more detail on Google Code.

TODO

- .swc distribution in addition to .as source files.
- get the adoption on the Wonderfl!

Comments for this is fully welcome. Thanks in advance. Enjoy!

[Perl] XML::TreePP - A pure Perl implementation for parsing/writing xml file

2009-06-30T15:37:00+09:00

XML::TreePP module parses XML file and expand it for a hash tree. And also this generates XML file from a hash tree. This module is a pure Perl implementation. You can also fetch an XML file from remote web server like an XMLHttpRequest object in JavaScript language. I think that XML::TreePP is enough fast and easy to use!

LiveChromaKey + LivePointers = AR Presentation!

Yusuke Kawasaki — 2009-05-30T21:48:47.575+09:00

I am a newbie for the wonderful ActionScript world and have worked hard for these two weeks to write a couple of pure ActionScript 3.0 libraries, LiveChromaKey and LivePointers. Then I gave a talk at Spark project's SparkStudy/09 on May 28th.

SparkStudy is a monthly meeting for the cutting-edge ActionScript developers in Tokyo. It's hosted by Yoshihiro Shindo a.k.a. yossy. This was the first time for me, an ECMAScripter, to attend it but I enjoyed it.

As recently posted, LiveChromaKey is a bluescreen-less image synthesizing engine for AR.

And the new library of LivePointers is a color detection engine to handle something as the new style of human interface devices with webcam. This means, for example, fingercap would be the 3D pointing device.

Anyway, you can try my presentation:
http://www.kawa.net/text/spark/09/spark.html

Yes, I was in the live projector screen during my presentation like weather newscaster did in weather news program! It would be nice for the audiences who seated at the end of the row in the room to see me on the screen. :)

In addition, I used fingercaps to manipulate slides, ex. right hand means next page. The fingercap I used costs only JPY 105, approximately USD 1.00- for six fingers. I'm sure that the cheap cap would be definitely important user interface device of the future!

Note that you can flip to the next page by right key of your keyboard as an insurance for the live presentation. :)

If you prefer a classical style of the slides, try slideshare:

JSARToolKit / LiveChromaKey / LivePointers

LivePointers library is still under development. You can try the current snapshot on the Spark project's repository:

LiveChromaKey - Bluescreen-less augmented IN reality (AR)

Yusuke Kawasaki — 2009-05-30T20:49:11.540+09:00

I wrote a new ActionScript library LiveChromaKey which is an image synthesizing engine for AR. The key point is it does not make something augmented ON reality but also augmented IN reality. It really portable as it never need blue background screen. The key color of chroma key is automatically detected on the fly.

Demo #1

Try: Travelling In Egypt
Source: Pyramid.as

An webcam is needed to try this. Blue background screen is not needed. At first, hide out from the camera for LiveChromaKey to recognize the background view. After few seconds, the pyramid of Khafre will be shown. It's time to play it! Now you can feel free you are travelling in Egypt. :)

In case you move camera, click the screen to re-recognize background on demand. Then hide out and wait for few seconds again. You may need to turn off your camera's intelligent features like automatic white balance, automatic exposure compensation, etc. LiveChromaKey does not like such tunings.

Demo #2

Try: Minority Report-like Demo
Source: Minority.as

This demo floats some photos in your back. Finger pointing reorganization like the Minority Report movie is not implemented at this time.

Demo #3

Try: Four Sprites Of LiveChromaKey
Source: Panels.as

This demo shows the four sprites which LiveChromaKey provides.

LiveChromaKey Sample Code

var chromakey:LCK_Core = new LCK_Core();
chromakey.init();

var spLive:Sprite = chromakey.getLive();
var spBack:Sprite = chromakey.getBackground();
var spMask:Sprite = chromakey.getMask();
var spFore:Sprite = chromakey.getForeground();

this.addChild( spLive );
this.addChild( spBack );
this.addChild( spMask );
this.addChild( spFore );

The getLive() method returns a sprite which shows the live video. You can use it as a background for your app.

The getBackground() method returns a sprite which shows the stationary background image. You can use it as a background for your app as well.

The getMask() method returns a transparent sprite which shows the blue mask image. You may not use it normally.

The getForeground() method returns a transparent sprite which shows the dynamic foreground image. It would contain a person or objects in front of camera. You can use it as a foreground for your app.

LiveChromaKey Properties

Set properties below before call init() method.

chromakey.captureX = 320;
chromakey.captureY = 240;
chromakey.captureFPS = 30;

Web camera input source's resolution and frame rate

chromakey.displayX = 640;
chromakey.displayY = 480;
chromakey.smoothing = false;

Output sprites' resolution and smoothing.

chromakey.workX = 80;
chromakey.workY = 60;

Working resolution by pixel.

The following method and property is for after it started.

chromakey.runDetector()

Method to re-recognize stationary background.

chromakey.ready

Boolean value for stationary background is detected.

How To Compile It

Download LiveChromaKey source code from the Spark project.

HTML5.Audio - JavaScript MP3 Player Library (HTML5-like)

Yusuke Kawasaki — 2009-05-23T12:02:44.600+09:00

HTML5 allows <audio> element to play MP3 and other sound formats by HTML and JavaScript. But HTML5 is still not in major. So I wrote HTML5.Audio which is a JavaScript library to play MP3 music via Flash.

Demo #1: Play sound by HTML5.Audio

Demo #2: MP3 player

Before Using It

You can manipulate HTML5.Audio object like HTML5's Audio object.
To prepare it, load three JavaScript files on HTML header.

<script type="text/javascript" src="js/swfobject.js"></script> 
<script type="text/javascript" src="js/jkl-js2as.js"></script> 
<script type="text/javascript" src="js/html5-audio.js"></script>

Plat MP3

Create HTML5.Audio instance with MP3 file URL. Then, call play() method to play it. It totally simple like HTML5's Audio object.

<script type="text/javascript"><!--

music = new HTML5.Audio('sound.mp3');
music.play();

--></script>

Note that HTML5.Audio library support MP3 files at this time.
WAV file and other sound formats are not supported. ActionScript's Sound class limits it.

Properties

HTML5.Audio library supports some properties imported from HTML5's Audio object: currentTime, volume, paused, ended, loop and duration
You need to call set()/get() method to set/get properties.

var ctime = music.get('currentTime');

music.set('volume',0.8);

Note that currentTime property will be updated only when playing music is started and paused.

Events

HTML5.Audio library supports some of events callbacked: onloadstart, onload, onplay, onpause and onended
You need to call set() method to set callback function for event property.

var onended = function () {
 alert( 'sound ended' );
}

music.set( 'onended', onended );

Options

HTML5.Audio library loads html5-audio.swf flash file which was written by ActionScript 3.0.
To set path for html5-audio.swf, call getProxy() method before creating the first instance of HTML5.Audio.

<script type="text/javascript"><!--

HTML5.Audio.Proxy.getProxy({swfPath:'./html5-audio.swf',onready: init});

--></script>

Note that onready property is an event which will invoked when HTML5.Audio library was ready to play. You can call getProxy() method before window.onload event was invoked.

Files

js/html5-audio.js - HTML5.Audio library core (JS part)
js/jkl-js2as.js - JS-AS bridge (JS part)
js/swfobject.js - Library to load flash file
swf/html5-audio.swf - HTML5.Audio library Flash binary
swf/expressInstall.swf - Says install/update Flash!

JSARToolKit - AR (Augmented Reality) by JavaScript

Yusuke Kawasaki — 2009-05-23T12:02:16.792+09:00

After my talk at OSDC.TW 2009 in Taipei, I've released JSAR's source code on the Spark project's repository:
http://www.libspark.org/svn/js/JSARToolKit/trunk

JSARToolKit is a JavaScript library to run AR (augmented reality).
This is the first JavaScript project on the Spark. :)

Demo #1 - Show Logo

Try: JSAR Logo Demo
Download and print marker pdf: Maker PDF (JSAR Logo Only)

Demo #1 shows a label "JSAR" in DIV element overlayed on Flash. Red square border on marker was drawn by canvas. It means both of label and lines are controlled by JavaScript not by ActionScript.

Demo #2 - Mic Volume

Try: Mic Volume Demo
Download and print markers pdf: Makrers PDF (4 patterns)

Demo #2 shows a label for each markers and changes its font size effected by microphone volume inputed.

Sample Code

<script type="text/javascript" src="../js/swfobject.js"></script>
<script type="text/javascript" src="../js/jsar.js"></script> 
<script type="text/javascript"><!--

  var jsar;
  function init () {
    jsar = new JSAR( 'jsar_here' );
    jsar.drawMarkerRect = true;
    jsar.onDetected = function ( result ) { ... };
    jsar.onLost     = function ( result ) { ... };
    jsar.captureX   = 320;
    jsar.captureY   = 240;
    jsar.displayX   = 640;
    jsar.displayY   = 480;
    jsar.init();
    jsar.setMarker( [ '../code/jsarlogo.pat' ] );
  }
  window.onload = init;
--></script> 
<div id="jsar_here"></div>

How To Compile It

JSARToolKit uses FLARToolKit in it. This means JSAR is not pure JavaScript, but flash powered. Download JSARToolKit from the Spark project by svn command, and compile it by Flash CS4 or by FlashDevelop + Flex SDK.

svn co http://www.libspark.org/svn/js/JSARToolKit/trunk jsar
mkdir -p jsar/src/org/libspark
svn co http://www.libspark.org/svn/as3/FLARToolKit/trunk/src/org/libspark/flartoolkit jsar/src/org/libspark/flartoolkit

In fact, you can use jsar.swf pre-compiled. So you don't need to compile it by your self.

I need say thank you to Saqoosha who has developed FLARToolKit.

JSAR (JavaScript Augmented Reality) at OSDC.TW 2009 Taipei

Yusuke Kawasaki — 2009-05-23T11:09:49.669+09:00

Last weekend, I flew to Taipei to attend the OSDC.TW 2009, OpenSource Developers Conference in Taiwan. I had a talk titled "The JUI Digest Taipei" there. JUI means JavaScript User Interface:

The JUI 2008 Tokyo (first)
The 2nd JUI Conference in Adobe MAX Japan 2009

In addition to the recent topics in the 2nd JUI, I showed the JASR (JavaScript Augmented Reality) demonstration.

JSARToolKit is a library to run AR by JavaScript. It works as a proxy wrapper for a bridge application using FLARToolKit.

Try it : JSAR Demo #1
Get marker PDF : JSAR logo for print
Get marker PDF : 4 markers for print

Then, today's main dish was "AiR Xiaolongbao".
A dozen XiaoLongBao (小籠包) were shown on the table by JavaScript!

Try it : AiR Xiaolongbao Demo
Get marker PDF : XiaoLongbao markers for print (free)

This was a hommage for Air Yakiniku (Air焼肉) as a Chinese version.

Some of front-row seated attendees helped me to show that JSAR supports multiple markers. Jesse drew his improvisatorial "JSAR" marker whis was fainally recognized at the last of my talk.

See my slides on slideshare.

The JUI Digest Taipei (JSAR) - OSDC.TW 2009

This was my sencond trip to Taipei. We really enjoyed there again. Last year, I gave another talk titled DOM manipulation by Wiimote/Gainer over HTTP in OSDC.TW 2008. That was also first time for me to talk about Wii Remote. I evolved it later and talked it in some other YAPCs places. I guess I will talk the JSAR again for other conferences this year as well. See you soon!

BTW, JSARToolKit uses FLARToolKit internally. I must say thank you for Saqoosha who is one of the most cool Japanese Flash guys. And he will give a talk about FLARToolKit in the FITC Tronto 2009 conference this weekend. Don't miss it!

tdserver - An Experimental HTTP Interface for Tokyo Dystopia

Yusuke Kawasaki — 2009-05-02T02:35:57.742+09:00

I just wrote an experimental HTTP interface for Tokyo Dystopia. Tokyo Dystopia is an open source full-text search system using Tokyo Cabinet which is very fast key-value storage by Mikio Hirabayashi. Some code is derived from Tokyo Tyrant which is a network interface of Tokyo Cabinet.

tdserver is also an open source project on CodeRepose.
http://svn.coderepos.org/share/lang/c/tdserver/trunk/

1. COMPILE

Compile Tokyo Cabinet, Tyrant, Dystopia and then tdserver.
You don't need to install them at this time.

wget http://tokyocabinet.sourceforge.net/tokyocabinet-1.4.17.tar.gz
wget http://tokyocabinet.sourceforge.net/tyrantpkg/tokyotyrant-1.1.23.tar.gz
wget http://tokyocabinet.sourceforge.net/dystopiapkg/tokyodystopia-0.9.11.tar.gz

tar zxvf tokyocabinet-1.4.17.tar.gz
tar zxvf tokyotyrant-1.1.23.tar.gz
tar zxvf tokyodystopia-0.9.11.tar.gz

cd tokyocabinet-1.4.17
./configure && make
cd ..

cd tokyotyrant-1.1.23
CFLAGS=-I../tokyocabinet-1.4.17 LDFLAGS=-L../tokyocabinet-1.4.17 ./configure && make
cd ..

cd tokyodystopia-0.9.11
CFLAGS=-I../tokyocabinet-1.4.17 LDFLAGS=-L../tokyocabinet-1.4.17 ./configure && make
cd ..

svn co http://svn.coderepos.org/share/lang/c/tdserver/trunk/ tdserver
cd tdserver
make

2. USAGE

See help message by -h option.

./tdserver -h
./tdserver: A server of Tokyo Dystopia

usage:
  ./tdserver [-host name] [-port num] [-thnum num] [-tout num] [-dmn] [-pid path] [-kl] [-log path] [-ld|-le] [-sid num] [-mask expr] [-unmask expr] [dbname]

3. START DAEMON

tdserver will create td_base directory then listen port 1977 as a HTTP server.

./tdserver -port 1977 td_base

4. ACCESS RESTfully

Three HTTP methods, GET, PUT and DELETE are accepted as RESTful interface.
Try it by Perl as follows.

* Insert (PUT method)

perl -MLWP::UserAgent -MHTTP::Request::Common -e 'print LWP::UserAgent->new->request(PUT "http://localhost:1977/1",Content=>"hello world")->as_string;'

This inserts a text "hello world" as a document #1.
ID# must be a positive numeric.

* Fetch (GET method)

perl -MLWP::UserAgent -MHTTP::Request::Common -e 'print LWP::UserAgent->new->request(GET "http://localhost:1977/1")->as_string;'

This returns document #1 directly.

* Search (GET method with query string)

perl -MLWP::UserAgent -MHTTP::Request::Common -e 'print LWP::UserAgent->new->request(GET "http://localhost:1977/?q=hello")->as_string;'

This searchs documents which contain phrase "hello" and returns ID numbers comma separated.

* Remove (DELETE method)

perl -MLWP::UserAgent -MHTTP::Request::Common -e 'print LWP::UserAgent->new->request(HTTP::Request::Common::DELETE "http://localhost:1977/1")->as_string;'

This removes document #1.

Feed backs and patches on CodeRepos are really welcomed.

The First Tokyo Cloud Developers Meetup was over.

Yusuke Kawasaki — 2009-04-12T10:12:37.401+09:00

As I mentioned, we had the first Tokyo Cloud Developers Meetup this Thursday with great success. It's got 64 registrants which is over capacity for the seminar room in Amazon Japan K.K. We'd like to have the next meetup. Join the group and stay tuned.

Photo by Gui Trento "Blue sky over the monday morning"

Above was the opening slide for the event. I love the picture of the beautiful blue sky with clouds. Thanks, Gui.

Keynote

Jeff Barr (Amazon) http://www.jeff-barr.com/

He gave us a talk in English without interpretation.
I guess most of Japanese attendees could understand most of what he said with help of his slides and demos.
He talked a bit faster in last half though. :-)

The busy evangelist had other conferences in Japan, the QCon Tokyo 2009 and an ITpro Technology Conference for Amazon Cloud Services. They cost JPY 30,000 for each, approximately $300. The guys who attended the more techy meetup were lucky because it's free of charge.

After his talk, Japanese developers gave lightening talks.

Tightening Talks

1. Yamazaki Yasuhiro - slideshare
2. Yuki Namikawa
3. Takao Funami - slideshare
4. Manabu Igarashi
5. Yukio Ando - slideshare

These were more techy and interesting.

This was my first time to come into Amazon's place in Japan. Nonetheless they provide the most popular cloud services in the world, they don't provide a connection to the cloud from the conference room in due to their security policy though. :-)
Anyway, most attendees surprised and regarded Amazon's nice office.

At last, I must say again thank you to Jeff Barr.
We're longingly awaiting the news from Amazon that provides the EC2 Asia region service with Japan zone servers.
