Seven months have passed since I changed my broken HDD, last December, to SSD on my Black Intel-based MacBook, the SSD was broken down again. SSD has done great jobs in terms of performance. Its speed of Reading and Writing was incredibly fast.

Today, my SSD is fixed and back to my Mac. He looks smiling with SSD in his brain.

WordPress 3.0, the thirteenth major release of WordPress is now out.

Major new features in this release include a sexy new default theme called Twenty Ten. Theme developers have new APIs that allow them to easily implement custom backgrounds, headers, shortlinks, menus (no more file editing), post types, and taxonomies. (Twenty Ten theme shows all of that off.)

Developers and network admins will appreciate the long-awaited merge of MU and WordPress, creating the new multi-site functionality which makes it possible to run one blog or ten million from the same installation.

WordPressの設定中に、memory sizeのエラーがでました。BlueOnyxのデフォルトでは16Mになっており、これでは足りないとのこと。
Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 233472 bytes) in /home/.sites/**/site*/web/blog/wp-admin/menu.php on line 214

設定方法は次のとおり。BlueOnyx上で、[サイトの管理] - [仮想サイト名] - [サービス] - [PHP]より、[Memory limit]をデフォルトの約2倍の30Mに増加させて、[保存]する。BlueOnyx上で設定を[保存]した場合、Apacheの再起動は必要ない模様です。

設定自体は、一般的には、/etc/php.ini上の「memory_limit」にて可能ですが、.htaccess上で「php_value memory_limit **M」とすることもできます。

open_basedirとは、PHPを実行できるディレクトリを指定したものに制限するための設定です。

phpinfo()で設定を確認してみると、以下のようにデフォルトで設定されています。
open_basedir /tmp/:/var/lib/php/session/:/home/.sites/28/site1/ /tmp/:/var/lib/php/session/

このWarningを無効にするには、</etc/httpd/conf/vhosts/site1>(仮想サイトsite1の設定)で定義されているopen_basedirを無効にします。

#php_admin_value open_basedir /tmp/:/var/lib/php/session/:/home/.sites/28/site1/
php_admin_value open_basedir none

apacheを再起動するのをお忘れなく。
/etc/init.d/httpd restart

なお、BlueOnyx上でも、open_basedirのLocal Value(仮想サイト特有の設定)を確認できます。

[サイトの管理] - [該当する仮想サイト名] - [サービス] - [PHP] - [Open basedir]

DTIのServersMan@VPS(エンジニアセット)を試しています。最近やっと開通。

このVPS上には、BlueOnyxというサーバ管理ツールがインストールされていますが、WordPressのインストール後のパーマリンクの設定についてメモしておきます。

蛇足ですが、OSはCentOSですが、BlueOnyxが動いているためウェブサイトのドキュメントルートが/var/www/htmlではなく、/home/sites/仮想サイト名/webにあったりして、慣れるまで少しわかりにくい。

パーマリンクの設定を変更し、.htaccessを手動で更新しましたが、更新後ブラウザで新しいパーマリンクにアクセスすると、エラーとなってアクセスできなくなってしまいます。

これは、BlueOnyx用の設定(/etc/httpd/conf.d/blueonyx.conf)で/home/.sites以下で有効なApacheの設定やAllowOverrideのディレクティブが定義されており、/home/sites/仮想サイト名/web以下での.htaccessがセキュリティ上の理由によりデフォルトでは禁止されています。

.htaccessを簡単に有効にするには、BlueOnyx上で、[サーバの管理] - [ネットワークサービス] - [ウェブ](ウェブの設定)でAllowOverrideのAllをチェック(有効に)します。

これで、WordPressのパーマリンク設定が有効になります。

iPadでのVGA出力についてのメモです(2010年6月1日現在)。

iPadは、Apple iPad Dock Connector - VGAアダプタを用いることで、プロジェクタやTVモニタ等上に画面を表示することができます。


ただし、iPad上の画面がすべて出力されるわけではなく、使用中のアプリがVGA信号を出力する場合のみ可能です。

以下、VGA出力対応状況です(2010年6月1日現在)。

Keynote(\1,200)

プレゼンテーション再生中のみVGA信号を出力

Photos

スライドショー再生中のみVGA信号を出力

Videos

再生中にVGA信号を出力

YouTube

再生中にVGA信号を出力

Safari

Web ページのビデオコンテンツのみ、VGA信号を出力

VGA出力対応のブラウザ

  • Web Brouser Presenter(\115)
  • web2vga(\115)
  • iDemoWeb(\230)
  • WebProjector(\600)
  • Expedition - VGA, Composite, Component Out Web Brouser(\230)
  • Infonet Presenter(\1,200)
  • Just PDF(\115) * PDFファイルを出力

これ、便利です。OmnigraffleやVISIOと同等のことが、ブラウザ上で利用できて、インストール不要。しかも無料。当然ですが、オンラインで図表を編集して、更新すると、埋め込んだ先の画像も更新されます。

本日、Twitterがツイートをブログ記事やウェブサイトに簡単に埋め込めるツールを発表した。

http://media.twitter.com/blackbird-pie/

ブラックバード・パイ(Blackbird Pie)と呼ばれるサービスで、使い方はとても簡単。引用したいツイートのURLをコピー&ペーストしてから「Bake it」ボタンをクリックすれば、プレビューが表示されるとともに、ブログやウェブサイトに貼り付けるソースコードが表示される。たったこれだけ。

個別のツイート自体が日に日に発言力を増している中で、重要なツイートを外部に簡単に張り付けられるため、重宝しそうだ。

tweet URL(個別のツイートのURL)を取得する方法は、各ツイートの下に表示されている更新日時(例えば「1 munute ago」)に貼られたリンクがこれになる。

例えば、次のように表示される。

RT @cinefugue @peterhchang Our first co-production "blink" is released on DVD today! http://bit.ly/9cju3M http://amzn.to/a15B7sless than a minute ago via web



自動生成されるソースコードは、とっても冗長だ。

また、更新日時が正確に表示されず、なぜか、上記の例の場合、「7:28 PM May 3rd via web」が「less than a minute ago via web」と表示されてしまう。なぜか、絶対的な日時を表示したり、生成されたソースコードから相対的な時間を計算したりしていない。なぜ?ツイッターは「リアルタイムメディアだー!」というのを、更新日時を偽ってでも伝えたいのだろうか?みんな知っているのに。

It is nothing new to say that Twitter's @anywhere is useful and essential.

Recently, Socialization of websites cannot be stopped. I have been thinking of what we are required to release next. That is a kind of easy-to-add API of socialization with, such as, adding just 1 line of JavaScript code.

Facebook's Social Plugin and Twitter's @anywhere are this kind of cloud solutions. Every kind of existing, old-styled website can integrate social functions without any efforts.

Recently, I had several conversations over email and social networking services with old friends of mine. It's been long since we met last and I haven't known what they have been doing so far.

Knowing that they are well and going ahead on their ways gives me spurs for boosting the morale. Things changes as time passes by. Something never changes.

Thanks great friends!

最近、大学時代の後輩の紹介で、異業種での勉強会に参加させて頂いています。

昨日は、参加し始めて2回目。内容は、IFRS(国際財務報告基準)の基礎や上場に向けた対応、日本での導入に関する国際的な位置づけなどでした。前回は、IPOの動向についてでした。



僕が参加させていただいている理由は、2つ。1つ目の理由は、現段階で自分自身に直接関わってくる内容ばかりではありませんが、近い将来、確実に意識しなければならない内容と確信しているからです。大学時代に「企業会計論」のような授業を履修して以来のことで、術語や基本的な概念の理解は深くないながらも、非常に丁寧に説明していただいているので、大切なエッセンスはつかむことができたように思います。IFRSに関しては、ソフトウェア産業、関連情報端末メーカ等には、IFRS完全移行に向けて、特需がありそうな予感です。

もうひとつの理由は、参加されている皆さん、講師の皆さんの人格が素晴らしいことです。今のところ、数回しかお会いしていませんが、ご経験や肩書やスキルや知識はさることながら、何よりも、謙虚で、温かいのです。僕にとっては、毎回、色々なことを教えて頂ける場であり、生きていく上で、仕事をしていく上で、一番大切なものが何かを教えていただけているように思います。

Tomorrow, I have my first race in this 2010 season, that is called "The Challenge Cycle Road Race." It is the biggest domestic clasic race in Japan.

Though I don't think I have prepared enough, I will do my best! I am pretty much excited to have a race!!
