Moving to the Bay Area

2012-01-15T08:51:00.000+09:00

Hello 2012,

For these 5 years, I have been working at the Media Technology Labs (MTL) which is a R&D department of Recruit Co., Ltd., one of the most largest information media publishing companies in Japan. The company is spreading its business field to the global market. At January of 2012, I'll soon fly to the Bay Area of the center of universe to launch our new R&D branch focusing the cutting-edge technologies of the Internet.

"Wisdom of Earthquakes" Released at TechCrunch Disrupt Hackathon SF 2011

2011-09-13T03:31:00.001+09:00

I'm attending the TechCrunch Disrupt SF 2011 held in San Francisco. Prior to the conference, I've hacked here at the huge hackathon filled with more than 700 hackers. It's a really exciting experience. I started hacking the "Wisdom of Earthquakes" web application and released it at the hackathon.

The hackathon started at Saturday noon and ended at the Sunday noon. Each team of hackers must finish their hack in 24 hours.

I've also posted articles about the event and food for hackers on my Japanese blogs in detail. TechCrunch's official report is here.

Wisdom of Earthquakes

After the lunch, the time has came for me to give a talk about my hack on the stage.

I've hacked "Wisdom of Earthquakes" which is a web application with a calendar and a map to tell the wisdom we can learn from earthquakes.

This calendar shows 500+ memorial days of earthquakes hit in the history of the globe. The oldest one listed is the 62 Pompeii earthquake in Italy. We could see almost every day on the calendar has had one or more earthquakes. The wisdom helps us do something to survive at the next coming disaster.

The app is shipped as an open source at:

iPad 2 JavaScript Benchmark Results 37% Faster Than iPad 1

2011-04-06T22:43:00.003+09:00

SunSpider JavaScript Benchmark marks 37% faster score on iPad 2 / iOS 4.3.1 / Mobile Safari 5.0 compared to iPad 1st gen.

Also note that iPad 1 could get significant peformance improvement by updating iOS from 4.2.1 to 4.3.1. This means Mobile Safari 5.0's "Nitro" Engine enabled on iOS 4.3 runs JavaScript quite fast.

Benchmark results captured are below:

iPad 2 - 4.3.1 and 4.3

iPad 1 - 4.3.1 and 4.2.1

PS.
My Mac results 344ms on Chrome and 360ms on Safari.
iPads are still nothing compared to Mac. :-<

KDrawSprite: Get GPU power without cacheAsBitmapMatrix on AIR for iOS

2011-02-14T23:20:00.001+09:00

KDrawSprite is an ActionScript library for mobile AIR applications using Packager for iPhone, AIR for iOS and AIR for Android to get more power of GPU. My iPhone app Korean Alphabet 1.2.2 is using this to get more than 30 fps on older devices, ex. iPod Touch 1st gen. A4 chip powered latest devices, such as iPad and iPhone 4, will performs 100 fps over with KDrawSprite.

Source on github:
https://github.com/kawanet/as3kawalib/raw/master/src/net/kawa/display/KDrawSprite.as
Document:
http://www.kawa.net/works/as/as3kawalib/docs/net/kawa/display/KDrawSprite.html

KDrawSprite draws your vector image onto a bitmap image. You don't need to manipulate cacheAsBitmapMatrix and cacheAsBitmap properties. These are powerful, however, sometimes make our app crashed erratically. You need take more care for iPad which has larger screen but has less memory.

How To Use This

Simply call KDrawSprite.getSprite() instead of setting cacheAsBitmapMatrix and cacheAsBitmap properties.

var sprite:Sprite = new Sprite();
sprite.graphics.beginFill(0x336699);
sprite.graphics.drawCircle(50, 50, 50);

// sprite.cacheAsBitmapMatrix = new Matrix(); // BEFORE
// sprite.cacheAsBitmap = true;

sprite = KDrawSprite.getSprite(sprite); // AFTER

addChild(sprite);
sprite.x = 100;
sprite.y = 100;
sprite.scaleX = 0.5;
sprite.height = 50;
sprite.rotation = 1;

Bitmap operations such as moving, scaling and rotation will be GPU enabled.
KDrawSprite will also free memory of image rendered when it comes out of the Stage.

You need call getSprite() or draw() method whenever you make changes on the vector source image. This also means any other needless re-rendering will not be invoked. Learn more on document.

Super Sampling Anti-Aliasing (2x SSAA)

KDrawSprite supports 2x SSAA, super sampling anti-aliasing, in addition to NoAA per default.

Note

To get better performance and rendering quality, you MUST set stage.quality as StageQuality.LOW. Also use 2x SSAA when needed.

stage.quality = StageQuality.LOW; // must

YAPC::Asia Tokyo 2010 - Japan's Perl Week

2010-11-01T01:04:00.015+09:00

Autumn is the best season for Perl hackers to come to Japan as we have the YAPC::Asia in Tokyo. This year, at September 15-16, I attended the great conference held at the Tokyo Institute of Technology Univ.

Thursday, September 14 - Pre-Conference Meetup

One day before the conference, we had the PerlCasual#4 developer meetup event organized by @yusukebe. The event was born as the antithesis of Shibuya.pm's technical talk events which were filled by too deep talks, such like x86, XS, binary etc., by super-guru hackers. Casual developers need another place.

At the event, I gave at a lightening talk "Reporting OSDC.TW - Shibuya.pm in Taipei." This April, we went the OSDC.TW 2010 conference in Taiwan. Shibuya.pm people, including me, gave talks there.

The first half of my talk reports the event and the reason we went there.
And the second is about my 3D JavaScript talks.
Try my slide here and push [3] key on your keyboard to view slides in 3D mode.

Photo (left): @obra's T-shirt shows he is a "Strange Alien."

(right): the Acmencyclopedia 2010 at the after-party of day #0.

Friday, September 15 - Conference Day #1

At the first day of the conference, I and my colleague @iandeth gave a talk. His slides are here. My part is about the Mashup Awards 6 (MA6), Japan's largest web application development contest. My slides are here.

The day #1's after-party was the official party held in the venue.
@clkao's T-shirt shows "Taiwanese." It's easy for us to see his nationality.

My ex-colleague @tsuyoshikawa is a Ruby guy but now working at a large PHP company. The company ordered him to give a talk at the Perl conference. It seems he is drunken from the stresses. :)

Saturday, September 16 - Conference Day #2

Day #2 was Saturday and sunny. Some speakers went down to a BoF looked like a picnic to have a beer under the sun.

On the other hand, as the closing keynote, @miyagawa gave us the great talk filled with many of suggestions and encouragements for developers. The talk was this year's best talk in my opinion.

He showed us the "Secret of success" that he found during his work for Plack and his other projects.

Secret of success

* Good artists borrow, Great artists steal
* Better late than too early
* JFDI (Just f* do it)
* STFUAWSC (Shut the f* up and write some code)
* TIMTOWTDI (There is more than one way to do it.)
BSCINABTE (But sometimes consistency is not a bad thing either)
* KISS (Keep it simple, stupid)
* glue language
* Naming

Thank you so much, the YAPC organizers and volunteers.

Sunday, September 17 - Hackathon

Sunday, we had the post-conference-hackathon at @hidek's.

After the hackathon, we went to a Chankonabe restaurant near @hidek's as the 4th after-patry. We had too many after-parties this week with a lot of fun!

Encode::JP::Emoji 0.60 Supports Unicode 6.0 Emoji!

2010-10-24T21:47:00.005+09:00

October 11, Unicode Consortium released Unicode Version 6.0 including Emoji code points and the mapping table. Then, today, I've just shipped Encode::JP::Emoji version 0.60 which supports encoding conversion for variant emojis between Unicode 6.0 and Japanese mobile phone carriers as a fast pure Perl module.

use Encode;
use Encode::JP::Emoji;

my $sun = "\xF8\x9F";
Encode::from_to($sun, 'x-sjis-e4u-docomo', 'x-utf8-e4u-unicode');
# U+2600

my $watch = encode_utf8 "\x{231A}";
Encode::from_to($watch, 'x-utf8-e4u-unicode', 'x-utf8-e4u-kddiapp');
# U+E57A

The code above means:

$sun: from DoCoMo's F8F9 (Shift_JIS) to Unicode 6.0's U+2600.

$watch: from Unicode 6.0's U+231A to KDDI's U+E57A (UTF-8).

Encode::JP::Emoji's Encodings

Encode::JP::Emoji modules provides numbers of encodings.

Check the figures below to see which encoding to fit for your use.

Group #1 uses each carrier's private code points as Perl's internal string which has UTF-8 flag on.

Group #2 uses Googles's private code points internaly. This means Google's encoding could be the interchange encoding for others.

Group #3 also uses Google's internal.
See Unicode 6.0's emojis are supported here.

Tha last group #4 rejects any emojis above.
Use this group with FB_EMOJI_TEXT fallback function.

For more detail, see POD documents on CPAN.

Shibuya.js won the prize at LT championship, LLTiger

2010-08-22T23:02:00.010+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. ; )

Memorial Service for Google Wave at Google's Tokyo Office

2010-08-22T18:25:00.005+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?

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

2010-08-07T00:48:00.011+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. :)

Meet again at YAPC::Asia 2010 Tokyo in October

2010-05-03T16:29:00.007+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

2010-05-03T15:09:00.007+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

2010-04-28T18:25:00.003+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.

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

2010-04-14T00:59:00.010+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!

2010-02-27T23:34:00.004+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

2010-02-27T22:23:00.003+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.

The Korean Alphabet, iPhone app built by Flash

2010-02-17T02:16:00.007+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.

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

2010-02-15T13:15:00.006+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!

LiveChromaKey + LivePointers = AR Presentation!

2009-05-30T21:27:00.004+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)

2009-05-23T13:54:00.003+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)

2009-05-23T11:55:00.003+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!

Download

Check out files from the Spark project repository:

JSARToolKit - AR (Augmented Reality) by JavaScript

2009-05-23T11:10:00.004+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.

tdserver - An Experimental HTTP Interface for Tokyo Dystopia

2009-05-02T02:23:00.005+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.

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

2009-04-26T04:39:00.005+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!

The First Tokyo Cloud Developers Meetup was over.

2009-04-12T10:03:00.004+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

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.

The history of JavaScript's 3D tech development

2009-03-17T10:47:00.011+09:00

Before most of popular browsers start to support canvas "3d" context, we JavaScript developers have struggled how to implement to enable 3D by JavaScript without any extensions like Java, Flash, etc. Here is a part of the history of JavaScript's 3D tech development.

Animation.Cube - April 2006

Three years ago, I wrote a library named Animation.Cube which slices images into many vertical lines to show rotating cube. I demonstrated this at the first technical talks of Shibuya.js community. The code is on JSAN. See also digg.

Triangles by Border of Div - October 2006

Useless Pickles (Jeff Lau) shows polygons drawn by many triangles made by <div> elements using trick of borders. It means we could develop Virtua Fighter (1) by JavaScript.

3D by Canvas - March 2008

Again, I wrote a new demo using <canvas> element to draw wireframe image and polygons as well. The code was written for another demo to manipulate Wii Remote controllers, I had sessions talked at OSDC.TW 2008 (Taipei), YAPC::Asia 2008 (Tokyo), YAPC::NA 2008 (Chicago), and YAPC::Europe 2008 (Copenhagen) conferences.

3D Renderer with Textures - March 2008

At just about the same time, Jacob Seidelin gave a great demo with texture mapped polygons using <canvas> element.

Triangle Texture Mapping on Wii - April 2008

Daniel Gump released Wii Opera SDK which had triangle texture-mapping feature. It is a SDK for Nintendo Wii's Internet Channel. He said it could show 500 textured triangles per second on Wii.

Motion Blur - May (maybe) 2008

Kaarel Lumi represented a beautiful motion blur using alpha blending tech by fillStyle. Thanks, @moriyoshi.

Projective Texturing - November 2008

Steven Wittens also wrote projective transform renderer. I'm interested in the tech which make an adjustment on size of the image cutted. It makes many cuts for front pieces.

Sphere Environment Mapping - February 2009

Satoshi Ueyama reported that Chrome had extremely fast canvas rendering engine named Skia by demonstrating his demos and benchmarks. He also described in detail how to implement texture mapping by canvas in his post. He also implemented physical computing and sphere environment mapping feature on it. His demos showed us that now we could run JavaScript 3D by real-time / daily-usable performance on Chrome. And I guess rest of popular browsers will soon come to the stage. See also my post.

Tweet this - a bookmarklet to post URL to Twitter

2009-02-26T18:26:00.003+09:00

This is my first bookmarklet.
The bookmarklet posts the current page's title and URL to Twitter. I guess many of similar bookmarklets would be found somewhere though.

Thanks, delicious!
I don't know the license type of the code snippet, however. ;-)

Incredible JavaScript+Canvas 3D demos from Japan!

2009-02-24T02:26:00.010+09:00

Mr. Satoshi Ueyama hacked out the new era of JavaScript 3D tech by unveiling the real of Google Chrome's power. Satoshi is one of the great JavaScript hackers in Japan, and also known as gyuque listed on the article of 30 Japanese geeks you should follow on Twitter. (cached)

He has introduced the brand new JavaScript technique using Canvas for 3D on his post. Browsing with Google Chrome is strongly recommended for all demos below.

I'm sure this could be one giant leap for JavaScript user interface technologies.

Demo #1: 3D texture mapped with physical computing

This is his first demo which shows 3D textured by Canvas. You can click on the cloth to make it waved.

http://gyu.que.jp/jscloth/

Demo #2: Hatsune Miku 3D with OOP

The 3D Miku is OO-style implemented as an object which has swing() method. This means she swings green onion in her hand when swing() method is called. Click on her.

http://gyu.que.jp/jscloth/miku.html
She wears hundreds of polygons. The demo was created for Paul Bakaus, jQuery UI lib's lead, visiting Japan.

Demo #3: 3D iPod touch with environment mapping

You may find the all demos above have the same width as 480px. Yes, it is definitely same as the horizontal viewport size which iPhone and iPod touch have. Now you can see iPod touch displayed on your iPod touch by the demo #3!

It could be slightly slow on ITSELF, however, it's still cool. These demos show us that we rarely need Flash anymore on the mobile platform, right? ;)

http://gyu.que.jp/jscloth/touch.html
But the most important point of the demo is not its width. You need to see behind of it. He also implemented the reflection mapping feature on his lib.

http://gyu.que.jp/jscloth/touch.html
The all demos above are coded only by pure JavaScript using Canvas. Here are no Java, Flash, ActionScript etc. but just the Web standards.

You can see Google Chrome runs all demos much faster than any other browsers. It has a great rendering engine named Skia. CPUs are already enough fast to calculate most things, you know, and now JITs are implemented as well. But canvas renderers admit of their performance. Skia is special. Safari is also fine. Firefox, 3.0 and 3.1 JIT-ed, are seem to be slower, unfortunately. We don't have to say that IE have no capability to run these.

Gyuque runs several benchmarks to describe Skia has significant advantage on its canvas rendering engine.

http://d.hatena.ne.jp/gyuque/20090211#1234364019
The 3D JavaScript tech could be one of the killer applications of Chrome now. I guess the next generation of browsers will soon compete on Canvas performance.

Original of this post was written for my Japanese blog.
You must see more detail on gyuque's post.

The 2nd JUI Conference in Adobe MAX Japan 2009

2009-02-15T04:18:00.002+09:00

Almost one year has been past since we held the 1st JUI conference in Tokyo. The JUI is a conference forcused into user interface techs using JavaScript. At he end of this January, we held the JUI again in Adobe MAX Japan 2009 conference as a sub conference. I think it's definitely true that Adobe is really big-hearted company. Five of JavaScript guys could talked only about JavaScript at the session which has the sub-title of "we don't need FLash any more!" in Japanese.

At first, I gave an introduction talk.

http://www.slideshare.net/kawa0117/jui-flash

JavaScript Hot Topics 2008 (Adobe MAX Edition)
#10 - 10th Anniversary of MM_SwapImage()
#9 - Shibuya.js comes to Kyoto
#8 - ECMAScript 4 failed. Now 3.1 instead.
#7 - Adobe launches Flash 10
#6 - iPhone 3G integrated with JavaScript
#5 - Many companies switching to JavaScript
#4 - Microsoft follows web standards by IE8
#3 - Varieties of JavaScript libraries
#2 - Playing .swf by JavaScript on the scene
#1 - Too Rapid JavaScript. No JIT, No Life.

The 2nd speaker was Yu Kobayashi a.k.a. yukoba who was the author of HotRuby virtual machine. His talk was about "How to implement a Flash Player."

http://www.slideshare.net/yukoba/flash-player

The next was Satoshi Ueyama a.k.a. gyuque. He also implemented another Flash Player named "JSplash" which had a trick to translate ActionScript code to JavaScript code. This pre-compiling feature gave it enough performance compared to Adobe's native Flash Player. That means we don't need flash player any more.

http://www.slideshare.net/gyuque/jsplash-adobe-max-2009

The 4th was Moriyoshi Koizumi who was one of Japanese PHP committers. He gave a talk about "JavaScript's Sound Generation" using data scheme.

http://www.slideshare.net/moriyoshi/adobe-max-japan-2009-jui-javascript

The last was Hotoshi Amano a.k.a. amachang. He always starts to develop new presentation tool before he writes slides for each conferences. Now he made it in 3D. Note that only nightly build of WebKits - at that time, now Safari 4 is available - could show his slides. His talk itself was about "DOM Performance Tuning."

http://amachang.sakura.ne.jp/misc/max/

Anyway, in the Adobe's conference, we're happy to let them know these crazy JavaScript guys're existing and working hard for the high level of techniques and user experience.

YAPC::NA 2008 in Chicago

2008-06-23T01:55:00.007+09:00

I have proudly attended YAPC::NA 2008 in Chicago and enjoyed that.
YAPC::NA is original yet another Perl conference since 1999.
You can see more my photos in Chicago on flickr.

YAPC::NA 2008 Pre-Conference Dinner

Ingy bring me to the restaurant by his motorcycle. ingy++

YAPC::NA 2008 (Day 1) Get it started

I attended every YAPC::Asias which were exciting and held three times in Tokyo. However, this is my first time to come to YAPC::NA.

YAPC::NA 2008 (Day 2) Just two seconds to generate .pm by WSST

I gave my first talk titled:
WSS - WebService Specification Schema and LL libraries
I still used JavaScript-powered S6 presentation tool with one-click translation feature for my slides.

YAPC::NA 2008 (Day 2) "Moose" by Stevan Little

Stevan Little gave a general talk about Moose:
Moose - A post modern object system for Perl 5
Moose is getting much popular also in Japan this year.

YAPC::NA 2008 (Day 2) "use the Moose;" by Ingy

Ingy döt Net gave an interesting talk about:
Perl and JavaScript
I like teh incredible the.pm module.

YAPC::NA 2008 (Day 3) Lightning Talks!

I gave another talk titled:
DOM manipulation by Gainer/Wiimote over HTTP.
Before starting presentation, I had a technical trouble with my real device gadgets, however I made it.
I'll give this talk again at YAPC::Europe 2008 in Copenhagen, Denmark.

YAPC::NA 2008 (Day 3) Improvised Lightning Talks

This is a brand-new style of lightning talk.
It's absolutely fantastic that Ingy's one thing which he'd never do in Perl.
He's true entertainer!

YAPC::NA 2008 is over

I appreciate the organizer Josh McAdams's hospitality. jmcada++

Differences between YAPC::NA and YAPC::Asia

I could find some of interesting differences between the conference and other conferences in Japan including YAPC::Asia.

* More foods and drinks
YAPC::Asia started to provide lunch and snacks this year.
Here are free drinks and delightful fruits provided in YAPC::NA.

* More interruptions
I think it's not common for Japanese audiences to interrupt speaker's talk to ask something. Dan-san could be probably only Japanese hacker who can do that? ;-)

* More chats in hall
Not only few people here prefer to stay at entrance to chat with another perl hackers rather than just listen presentations.

* More BOFs
I don't see such concurrent meetings which occur naturally in Japan.

* More women
Josh said that there were 17 women in second day's conference dinner.
It's definitely rare that we could have two-digit numbers of women attend such technical conference in Japan.

* Less technological previews, more productive solutions
Personally, I love talks about cutting-edge technologies, future glances, ingenious topics etc. We can see such "I-Made-It!"-styled talks in Japan.
Here, more speakers provide solutions for attendees' daily production.

* Few Japanese attendees
I was only Japanese attendee come from Japan.
I hope more Japanese hackers could come to give their techs out for global.

My slides using S6 again is below. (written in Japanese)
http://www.kawa.net/text/google/gdd2008/japan.html

The conference was completely for developers who love Google. I am not Google's employee, you know, but I have surprised that more than 100 attendees have nevertheless come to my room.

In addition to my talk above, I took the platform of keynote to demonstrate in favor for OpenSocial.
We provides a trial service which uses an OpenSocial's container of Shindig.

YAPC::Asia 2008 Tokyo - DOM manipulation by Wiimote/Gainer over HTTP

2008-05-17T16:28:00.006+09:00

I love YAPC::Asia which is really exciting Perl conference.
At YAPC::Asia 2008 Tokyo of this week, I got first chance to give a talk in the conference.

My talk was titled DOM manipulation by Wiimote/Gainer over HTTP.
Some slides are updated from OSDC.TW 2008's one.
I'll give this talk again for YAPC::NA 2008 in Chicago next month.

The room was almost full and had some standees at last!
Thank you for coming to listen my talk.

The venue of the conference was Tokyo Institute of Technology at Ookayama, Tokyo.
It had many trees in the campus and was really nice venue.
The number of attendees was counted as more than 500 people.
The committee announced that the conference cost about three million yen (about USD 30,000) in total.
I'd love to say thank you for organizers and volunteers.

As an aside, RECRUIT Co., Ltd. was one of the gold sponsors of the conference. It was honor of us. The Media Technology Labs have a plan to back up such open source related conference and projects.

Translatable presentation with the S6 JavaScript library

2008-05-03T03:08:00.008+09:00

For my talk at OSDC.TW 2008 in Taiwan, I have added a couple of features to the S6. The S6 is a great presentation tool developed by amachang, based on HTML/Web standards and implemented in pure JavaScript. (demo)

Writing a slide with the lib is entirely easy:

<div class="s6_fadeScale">
    <h3>page title here</h3>
    <p>page body here</p>
</div>

class="s6_fadeScale" means the fading/scaling effect on paging.

And the most noteworthy feature of this special version of the S6 is automatic translation feature which is powered by Google AJAX Language API.

Just clicking a text node on the slide, it's translated into Japanese or another language in a moment. This is efficient for I18N, M17N and native language support. (demo)

13 languages, Japanese, Korean, Traditional Chinese, Simplified Chinese, Arabic, Russian, Greek, German, Italian, Dutch, French, Spanish and Portuguese, are supported to be translated into. The number of languages is depend on it of the Google Translate. Reverse translation, ex. translating from Japanese to English, is also supported for granted.

This means, with the lib, your presentation would get more familiar for the people who could not read the language of it.
I'll welcome you giving cool talks in Japan with the lib. We Japanese don't need to be afraid of slides written in English anymore! :-)

Download it now and enjoy!

OSDC.TW 2008 - DOM manipulation by Wiimote/Gainer over HTTP

2008-05-03T00:58:00.010+09:00

12th April, I gave a new talk titled "DOM manipulation by Wiimote/Gainer over HTTP" for the OSDC.TW 2008 at Taipei.

I think manipulating DOM is a bother. That is why I have developed the JKL.ParseXML and XML.ObjTree libraries for my use. And I was involved in kinds of real device web service techs in these days. The presentation could be an answer from me about DOM manipulation. ;-)

The same titled talk will be soon made again in both of the YAPC::Asia 2008 Tokyo and the YAPC::NA 2008 at Chicago.

Special thanks:
* Hiroshi Nemoto - Wiimote HTTPd's co-author
* Hitoshi Amano (a.k.a. amachang) - S6 presentation tool's author
* Shuhei Terai (a.k.a. trick7) - Gainer's maestro

Anyway, this was my first time to get to Taiwan. I must say that the Formosa was the great island of good foods and kind full people.

After the conference, I moved to gugod's office in the Jhubei City which is next to Hsinchu. I love 小籠包 (Xiaolongbao) above, however, 潤餅 (Taiwanese crepe) at a street stand was really tasty.

I'd love to back to Taiwan again next year. More photos...

[Event] OpenSocial - Google JAPAN's developer roundtable #5

2008-04-13T15:54:00.004+09:00

At 14th March, I have participated in the Google JAPAN's developer roundtable as a panel member.

The the great venue was the Aoyama Diamond Hall, Omote-Sando.

The official report from Google is out:
Google JAPAN's developer roundtable #5 - OpenSocial

I introduced the Dokoiku's experimental OpenSocial container implemented with Shindig.

"Gainer over HTTP" and the Device::Gainer module for Perl

2008-02-09T21:57:00.000+09:00

Gainer is one of the hottest gadgets now.
This weekend, I got the module lent by Shuhei Terai, my colleague and a great Flash/ActionScript developer a.k.a. Trick7.

Gainer is an environment for user interfaces and media installations. By using the Gainer environment, the user can handle sensors and/or actuators with a PC on various programming environments such as Flash, Max/MSP, Processing and so on.
http://gainer.cc/Main/HomePage?userlang=en

Gainer supports some of LLs, ActionScript and Ruby (with Funnel).
Perl is not supported yet unfortunately.

So I wrote a Perl module named Device::Gainer and submitted on CodeRepos:
http://svn.coderepos.org/share/lang/perl/Device-Gainer/trunk/lib/Device/Gainer.pm

SYNOPSIS:

use Device::Gainer;
my $gainer = Device::Gainer->new( host => '192.168.1.xx' );
$gainer->on_pressed( sub { print "PRESS\n"; } );
$gainer->on_released( sub { print "RELEASE\n"; } );
$gainer->turn_on_led();
$gainer->turn_off_led();

The module has enough functionality for my purpose, however,
it's not completed especially for documents and tests.
The following methods are supported currently:

Method	Command
`turn_on_led`	h*
`turn_off_led`	l*
`digital_output`	D____*
`set_high`	H_*
`set_low`	L_*
`peek_digital_input`	R*
`analog_output`	a___*
`peek_analog_input`	I*
`on_pressed`	N*
`on_released`	F*

Anyway, I wrote a proxy server for "Gainer over HTTP" using the Device::Gainer and POE::Component::Server::HTTP module.

Now we can use the Gainer through the Internet!
This means the Gainer Ajax tech can be the hot topics in the Ajax/JavaScript developers as well...

I failed to use Win32::SerialPort module to connect to Gainer module directly.

[JSONP-SE] JSONP Static Emulation

2008-01-26T03:44:00.000+09:00

JSONP, JSON with Padding, is available not only with dynamic contents from server-side CGI etc., but also with static contents, just static files.

However, such static JSONP files do NOT allow to change Padding, name of callback function.
JSON with FIXED padding is a kind of JSONP? It's just a mere JavaScript file?

callback(
    { foo: 'HOGE', bar: 'POMU' } // JSON content
);

You may need to manage a queue when you handle multiple JSONP calls.

Now, the JSONP-SE is the solution for this.
JSON-SE means JSON Static Emulation.
Change the padding, "callback" in code above, to the six lines below:

( function (data) {
    var list = document.getElementsByTagName( 'script' );
    var temp = list[list.length-1].src.match( /[\?\&]callback=([A-Za-z0-9\_\.\[\]]*)/ );
    var func = temp ? temp[1] : 'callback';
    eval( func+"(data)" );
})(
    { foo: 'HOGE', bar: 'POMU' } // JSON content
);

This is still a static file, however, you could specify any callback function name you like.
The JSON content in JSON-SE is exactly the same as it in JSON.

You could load JSONP-SE file via <script> element in <body> element.

<script type="text/javascript" src="test.js?callback=hello"></script>

The callback function "hello" would be called.

<script type="text/javascript" src="test.js"></script>

Without ?callback=... argument is not specified, the default function "callback" would be called instead.

You could generate <script> element via DOM.

    var script = document.createElement( 'script' );
    script.charset = 'utf-8';
    script.type = 'text/javascript';
    script.src = 'test.js?callback=hello';
    document.lastChild.appendChild( script );

JSONP-SE must be loaded in the bottom of the dom tree.

Such trick, fetching argument from the src attribute of the script element loaded, is used in script.aculo.us as well.

[Event] Tokyo ActionScript Meetup 2008 F/ Colin Moock

2008-01-17T11:57:00.000+09:00

When I heard that Colin Moock would come to Japan to make a talk in a seminar event sponsored by Adobe Systems Inc., it hit me that we could welcome and counter him with top ActionScript engineers in Japan!
I'd like to show him the cutting-edge ActionScript techs developed in Japan, are not introduced yet to the world in English, unfortunately.

As the result, at the day of January 16, the Tokyo ActionScript Meetup 2008 F/ Colin Moock was taken a place in Adobe Japan.
Very deep tech talks about ActionScript 2, 3 & also 4(!) were told.

Colin (left) and Ota-san.

The last of all, I asked him some of questions invited by the audiences on ahead.

I think the most of audiences including me would surprised that he could speak Japanese much fluently.
As Larry Wall could speak JavaScript as well, such great programmers would be good at speaking multiple natural languages as well as programming languages.

Hatsumode at the Sanno Hie Shrine

[Event] Web 2.0 EXPO Tokyo "JavaScript Labs"

2007-11-17T21:31:00.000+09:00

I gave a presentation on Web 2.0 EXPO Tokyo (day 1) with TAKESAKO and amachang. This talk was titled as "JavaScript Labs" and introduced the cutting-edge JavaScript technical topics and what we had interest for now.

At my part of the session, I talked about JavaScript's today and its future. And also I focused into my attending to Facebook and OpenSocial.
I'm wanting to see them. FBJS is early days, and OpenSocial is still version 0.5 and full of uncertainty at this time though.
I showed tiny demo application for OpenSocial:

The room we made a talk was soon fulled with about 100 audiences.

Thank you all very much for attending our session and see you soon again!

[Perl] I18N Date Representations with DateTime module

2006-08-28T04:52:00.000+09:00

DateTime module makes easy to get an I18N date representaion.
The code below displays date strings in some languages.

use Encode;
use DateTime;
foreach my $lang (qw( de el en es fr ja nl no pl pt sv tr vi )) {
  my $fmt = DateTime::Locale->load($lang)->full_date_format();
  my $date = DateTime->now(locale => $lang)->strftime($fmt);
  my $line = "$lang : $date\n";
  print encode_utf8($line);
}

The result of today is following:

de : Sonntag, 27. August 2006
el : Κυριακή, 27 Αυγούστου 2006
en : Sunday, August 27, 2006
es : domingo 27 de agosto de 2006
