YAPC::NA 2008 in Chicago

Yusuke Kawasaki — 2008-06-23T02:39:00.880+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 (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.

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

Yusuke Kawasaki — 2008-05-17T17:37:54.907+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.

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

Yusuke Kawasaki — 2008-05-17T16:28:18.908+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...

Translatable presentation with the S6 JavaScript library

Yusuke Kawasaki — 2008-05-03T06:02:00.335+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!

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

Yusuke Kawasaki — 2008-04-13T17:17:46.931+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

Yusuke Kawasaki — 2008-02-09T22:45:56.435+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.

[Event] Web 2.0 EXPO Tokyo "JavaScript Labs"

Yusuke Kawasaki — 2008-02-05T01:07:02.844+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.

(photo taken by TAKESAKO)

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!

Re: Multiple category documentation in XML::FeedPP misleading

Kawasaki Yusuke — 2008-02-02T06:26:17Z

Antti and all, Hello from Japan. Thanks for your mail and suggestions. About the enclosure element for podcasting, I wrote an example only in the page below

[JSONP-SE] JSONP Static Emulation

Yusuke Kawasaki — 2008-01-26T03:48:41.099+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.

Lingua::JA::Romanize::Japanese module parses Japanese characters, both of Kanji and Kana. Lingua::KO::Romanize::Hangul module parses Korean characters, Hangul.

[Event] Tokyo ActionScript Meetup 2008 F/ Colin Moock

Yusuke Kawasaki — 2008-01-17T13:47:24.146+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.
