2011 - SMS authentication in Google Apps is available for all. SharePoint keeps calm

Google Apps SMS

Two-factor authentication, which has been available for users of paid Google Apps account since September 2010 is now available in all free GMail and Google Apps accounts. Recall that unlike the usual authorization the two-factor authentication includes the second step - entering the secret code received via SMS or generated by mobile application (for Android, iPhone or BlackBerry). This authentication method is often used in online payment systems and Internet banking services, because it ensures a high level of security. If you are working on one computer you won't enter the code very often because authorization will be done automatically. So you won't feel any inconvenience, but will considerably improve your data security. You can activate the two-factor authentication on this page.

2009 - Hacker team will help to push Google Apps - a new advantage over SharePoint

Google Apps

Google opened a new front in the war for business users. At that time Google pushes the idea that companies appreciate openness of business applications, i.e. the possibility to import/export their data to/from these apps. At the same time the leading business software vendors (IBM, Microsoft) use to lock user data and don't provide easy tools to export it in the needed format. The new Google's project Data Liberation Front contains information about how to export data from Google applications. For example it gives guidelines of how to use GMail over POP3 and IMAP protocols, or how to export Google Calendar in ICAL format.

When introducing the project in the company blog, Google representative gave some details of the nearest liberation efforts: Google Sites export to HTML, and bulk Google Docs export to OpenOffice and MS Office formats.

But the Data Liberation Front team will not only "liberate" the data stored inside Google applications. Their mission - is also to liberate data that is (still) stored in the competitive systems. For example, recently Google introduced tools that enable to import data from Hotmail, Yahoo, MS Exchange, Lotus Domino. So the Google developers will "crack" the third-party applications to help users move their data to Google Apps.
