第1回 そもそもGoogle Gearsって何?:ITpro - 0 views

  • 公式ページには,とても少ない説明の中にGoogle Gearsの特徴3点が紹介されています。対訳をつけてみます。 Store and serve application resources locally ローカルにアプリケーション・リソースとデータを保持して実行します Store data locally in a fully-searchable relational database ローカル・データは完全な検索機能を持つリレーショナル・データベースに保存されます Run asynchronous JavaScript to improve application responsiveness Javascriptは非同期に実行され,更新の必要に応じてアプリケーションと通信します  この解説は今までの説明で述べてきたものと変わりありません。特に詳説は必要ないでしょう。この三つの概念が以下のように,それぞれAPIグループとして実装されています。 ローカル・サーバー(LocalServer) データベース(Database) ワーカープール(WorkerPool)
  • アプリケーションがデータの入出力を必要とする場合,データはデータベースに格納されます。Google Gearsを導入した段階で,ローカルマシンの中にデータベースが作成されるわけです。このデータベースを操作するのが「Database」API群になります。データベースが導入されるといっても,MySQLやPostgreSQLのように巨大な物がインストールされるわけではありません。  このデータベースの実体は,SQLiteです。SQLiteはアプリケーションに組み込んで使用されるのを目的とした軽量なデータベース・エンジンです。データベース・サーバーにつきもののユーザーのような概念がなく,データの出し入れを主眼としてシンプルに設計されています。SQLiteは日本語2バイト文字も通ります。
  • 最後の「WorkerPool」は,インターネット上のコンテンツをローカルにキャッシュするコントロールを担当します。ローカル側サーバー機能という言い方もできそうです。Poolの名前の通り,まさに貯め込んでおくという感じです。言葉で説明することは難しいので,WorkerPoolについては後半のサンプルも眺めながら確認してください。  なお上記の三つのAPI群のほかにいくつかのAPI群があります。一つは「Factory」です。FactoryはGoogle GearsのコアとなるAPIで,LocalServer,Database,WorkerPoolのインスタンスを作成するのに使用されます。
  • ...2 more annotations...
  • 2007年8月末にGoogle Gearsはバージョンが0.2に上がり,「Timer」と「HttpRequest」が追加されました。Timerは文字通りタイマー管理をするAPI群です。一定間隔で処理を行いたい場合に使用します。タイマー機能そのものはJavaScript本体にもあります。Google GearsのTimer機能も書式はJavaScriptのタイマーと同じになっています。Google GearsのTimerはローカルにキャッシュしたコンテンツ(WorkerPool)に対しても,メインのHTMLに対しても利用可能だと説明されています。  「HttpRequest」は自身以外のコンテンツに対してHTTPヘッダ,あるいはデータを送信し結果を受信することができるAPI群です。機能と名前からも想像できるようにDOM/AjaxのサンプルとしてよくでてくるXMLHttpRequestのGoogle Gears版といえます。HttpRequestもTimer同様にベースになったXMLHttpRequestと書式,関数,プロパティがほぼ共通です。
  •  Google Gearsはオフラインで動作しなくてはならないため,サーバー側の処理には頼れません。そこで,処理動作をローカルのブラウザだけで完結できるようにするために,処理言語としてJava Scriptを使用します。Java ScriptはローカルのPC側に処理エンジンがあり,オフラインであっても動作します。  このシステム全体をGoogleはBSDライセンスとして公開すると宣言しました。私たちは「このシステムはGoogle Gearsを使っている。著作権はGoogleにある」と著作権明記さえすれば,自由に使用できます。業務か趣味かを問わず,Webアプリケーションを作成しているプログラマにとって,Google Gearsは何かしらの意識革命を引き起こしえる存在に感じられます。つまりGoogle Gearsはそれ自体がGoogleマップやYoutubeのように直接ユーザーに何か便利なサービスを与えるというサービスではなく,ユーザー向けにWebアプリケーションを作成しているプログラマに対しての技術サービスだというわけです。

A-NOTE - 『Googleドキュメント』やめて『Zoho』にしようかな - 0 views

  • オンラインでワードプロセッサ、表計算ソフト、プレゼンテーションツール、プロジェクトやタスクの管理ツール、CRMサービス、データベース構築などなどが無料で使える『Zoho』ですが、Googleアカウントや米Yahoo!アカウントで利用可能になったようなので、早速使ってみました。 私の個人用PCにはMicrosoftオフィス関連ソフトが一切入ってません。(ほとんど使わないので) いざとなったら、Google ドキュメントでもあるし。 …と思ってましたがZohoはGoogle ドキュメントより使いやすい。 Google ドキュメントで表を作ろうとしたものの使いづらくて(わかりにくい)、あっさり断念した私ですが、 Zoho Sheet(オンライン表計算)だとさくっと作れちゃいました。

Cloud security: Feds on cusp of change -- Federal Computer Week - 0 views

  • Virtualization has been setting the stage for many of these issues for years, he said, but “what cloud computing is forcing us to look at is the survivability of systems…and protecting the data,” Hoff said. “While I hear the perimeter is going away [as a security approach], I disagree; it’s multiplying and the diameter is contracting,” Hoff said. “You’re going to outsource responsibility, but not accountability. So we need open standards and better visibility.”
  •  
    Interesting view on depermeterisation. Hoff's view is that the protected assets are in smaller clumps and still have a perimeter.

  •  
    Informational self-determination refers to the ability of individuals to exercise personal control over the collection, use and disclosure of their personal information by others. It forms the basis of modern privacy laws and practices around the world. [...] At the Office of the Information and Privacy Commissioner of Ontario (IPC), we have long advocated a strong role for individuals in managing their personal information, not just by exercising their privacy rights under Ontario law, but also by becoming better informed and using privacy-enhancing technologies (PETs). [...] This paper explores what will be possible if proper digital identity services are deployed and the full power of Cloud computing is realized.

Hyper-Scale your Microsoft Azure Business - 0 views

  •  
    Service providers need to realize that the Cloud business is different than their earlier offerings - traditional hardware or solution and infrastructure managed services. They must transform quickly and direct their focus on modern applications, platform-as-a-service (PaaS), or containers and PaaS rather than just on infrastructure management. The only way forward is to incorporate agility in operations, leverage new-age toolset, establish governance, increase optimization, and invest in security as an integral part of managed services.
