Googleカレンダーで予定を作る(第44回):深川岳志「Google探検隊」 - 0 views

  • 前回を参照していただければ、だいたいの使い方は分かると思う。すでにGmailを使っている方なら、画面左上に表示される「カレンダー」という文字をクリックするだけで自分のカレンダー画面にジャンプすることができる。Gmailアカウントを取得した辞典で環境は用意されているのだ。  あとは予定を携帯電話で確認できるようにするとか、iGoogleのガジェットを使ってカレンダー画面に行かなくても予定がわかるようにするといった工夫をすれば、紙の手帳並の使いやすさが実現する。  今週は、紙を超えてしまおう。  紙の手帳の長所は携帯性で、短所は共有性だ。手帳は良くも悪くも自分だけのもの。予定のほとんどは他人との関係性のなかで生まれるから、電話やメールといったツールを使って、自分でコツコツと作り上げていくほかない。  自分の都合はわかっても、他人の都合まで勝手に決めるわけにはいかないからだ。  Googleカレンダーには共有という強力な武器がある。

Cloud Computing Poses E-Discovery, Legal Risks - 0 views

  • Cloud Computing Poses E-Discovery, Legal Risks April 10, 2009By Marty Foltyn ORLANDO, Fla. — Cloud computing was a hot topic at this week's Storage Networking World show, but one attorney sounded a warning note about the rush to the cloud. In a presentation titled "Computing (strike that — Litigation) in the Cloud," Steven Teppler, senior counsel at KamberEdelson in New York, said cloud computing and services are a corporate counsel's nightmare. The 2006 e-discovery amendments to the Federal Rules of Civil Procedure (FRCP) changed the legal and corporate information landscape, putting custody and control at top of mind. "Cloud computing means that data may always be in transit," said Teppler, "never anywhere, always somewhere." And that creates a big challenge for corporate counsel. How can they identify "who, when and where" in the cloud? How can organizations handle document retention? And to add another layer of worry, information targeted for the cloud may also be subject to laws requiring privacy and persistent data integrity, and other requirements that the storage manager may not even be aware of. Teppler spelled out the top cloud computing shortcomings: no native security attributes; inadequate or no security provisioning by providers; the lack of understanding of cloud legal issues (a real problem for not only cloud computing providers, but also corporate counsel and IT consultants); and the failure to recognize potential liability from either legal issues or a lack of security. Teppler told the audience that litigation in the cloud is already here. Users of cloud services will need to insist on service level agreement (SLA) terms with their providers to ensure legal and regulatory compliance, searchability, demonstrable customer care (security), provably persistent data integrity and reliability, and demonstrable storage security and integrity for electronically stored information in the cloud.

OpenSocial in the Cloud - OpenSocial - 0 views

  • Apps can grow especially fast on social networks, so before you launch your next social app, you should think about how to scale up quickly if your app takes off.
  • Unfortunately, scaling is a complex problem that's hard to solve quickly and expensive to implement.
  • If this app grows to serve millions of users and photos, shared hosting or even a dedicated server won't have the bandwidth or CPU cycles to handle all of the requests. We could invest in more servers and network infrastructure, shard the database, and load-balance requests, but that takes time, money, and expertise. If you'd rather work on the new features of the app, it's time to move into the cloud.
  • ...9 more annotations...
  • It's important to focus on the interactions between the app and your server when designing an application that will run in the cloud. If we standardize the communication protocol and data format, we can easily change the server side implementation without modifying the OpenSocial app.
  • You can configure the makeRequest method to digitally sign the requests your app makes to your server using OAuth's algorithm for parameter signing. This means that when your server receives a request, it can verify that the request came from your application hosted in a specific container. To implement this, the calls to makeRequest in the OpenSocial app spec XML specify that the request should be signed, and the code that handles requests on the server side verifies that a signature is included and valid
  • When our server receives a request, we can verify that it came from our application by checking that the digital signature was signed by a valid container and that the application ID is correct.
  • Since our server isn't storing any relationship data, the app will need to send us a list of user IDs so we can fetch the appropriate photos.
  • Although it's outside the scope of this article, we could provide a mechanism for our OpenSocial app to request a one-time-use token that it would include in the request to upload a photo.
  • Note that the post data is URL-encoded in the request so the post method uses urllib.unquote before splitting the comma-separated list of person IDs.
  • Since the server doesn't store any relationship data, the PhotosHandler class checks the post data of the request for a list of IDs from the container.
  • A common misconception when coding in the cloud is that storage space, CPU cycles, and bandwidth are unlimited. While the cloud hosting provider can, in theory, provide all the resources your app needs, hosting in the cloud ain't free so these resources are limited by your budget. Luckily, OpenSocial provides several mechanisms to cache images and data that will reduce the load on your server.
  • In addition to reducing traffic to our server, this technique has the added benefit of being fast—requesting data from the Persistence API is much faster than making the round trip to your server.
  •  
    Some OpenSocial apps can be written entirely with client-side JavaScript and HTML, leveraging the container to serve the page and store application data. In this case, the app can scale effortlessly because the only request hitting your server is for the gadget specification which is typically cached by the container anyway. However, there are lots of reasons to consider using your own server: * Allows you to write code in the programing language of your choice. * Puts you in control of how much application data you can store. * Lets you combine data from users on multiple social networks. * Enables interaction with the OpenSocial REST API. Setting up an OpenSocial app that uses a third party server is fairly simple. There are a few gotchas and caveats, but the real issues come up when your app becomes successful - serving millions of users and sending thousands of requests per second. Apps can grow especially fast on social networks, so before you launch your next social app, you should think about how to scale up quickly if your app takes off. Unfortunately, scaling is a complex problem that's hard to solve quickly and expensive to implement. Luckily, there are several companies that provide cloud computing resources-places you can store data or run processes on virtual machines. These computing solutions manage huge infrastructures so you can focus on your applications and let the "cloud" handle all the requests and data at scale. This tutorial focuses on a simple photo-sharing app that uses a third-party server to host photos and associated metadata. If this app is going to host millions of images and support many requests per second, we won't be able to run it on a single dedicated host. We'll break the app down and analyze the interactions between the OpenSocial App and the back end server. Then we'll implement the app in the cloud, first using Google App Engine, then leveraging Amazon's S3 data storage service. Finally, we'll look at s
