By Stuart Gill, sfntly Architect

Today we’re releasing the sfntly font programming library as open source. Created by the Google Internationalization Engineering team, the sfntly Java and C++ library makes it easy for programmers to build high performance font manipulation applications and services. sfntly is really, really fast: Raph Levien, Google Web Fonts Engineer, says, "Using sfntly we can subset a large font in a millisecond. It’s faster than gzip'ing the result."

Starting today, both Java and C++ programmers can use sfntly to quickly and easily develop code to read, edit, and subset OpenType and TrueType fonts. The Google Web Fonts team uses the Java version to dynamically subset fonts, and the Chrome/Chromium browser uses the C++ version to subset fonts for PDF printing.

sfntly (\s-’font-lē\) was built from the ground up to provide high performance, an easy to use API, and both high-level and low-level access to font data. Font objects are both thread safe and high performance while still providing access for editing. After about a year of internal development sfntly is stable enough to move it into open source and share with others.

Currently, sfntly has editing support for most core TrueType and OpenType tables, with support for more tables being added. Using sfntly’s basic sfnt table read and write capability, programmers can do basic manipulation of any of the many font formats that use the sfnt container, including TrueType, OpenType, AAT/GX, and Graphite. Tables that aren’t specifically supported can still be handled and round-tripped by the library without risk of corruption.

sfntly is already capable of allowing many really exciting things to be done with fonts, but there is much more planned: expanding support for the rest of the OpenType spec and other sfnt-container font formats, other serialization forms, better higher level abstractions, and more.

I encourage you to you join us on our journey as a user or a contributor.

Seo Master present to you: By Itai Raz, Google Visualization API Team

Today, we're publicly documenting the Google Visualization API's open-wire protocol, thus dramatically expanding the capabilities of this API beyond what had been available since we first launched in March of this year. Organizations can now expose their server-side data, such as in SQL databases and even in Excel spreadsheets, and display this data through visualizations from our growing directory. This flexibility makes it possible to connect easily almost any data source to a wealth of 40+ visualizations, including standard pie and line charts and complex heat maps and motion charts.

To make it even easier for developers to get started, we have documented an open-source Python library that enables any Python developer to quickly start using the API. What we find particularly cool about this library is that it also runs on Google's AppEngine. You don't even need to be an owner of your own servers to expose your data: You can place it on AppEngine and use the Visualization API to expose your data in meaningful, insightful ways in dashboards and reports. Expect to see additional server-side tools for the Visualization API in the near future.

Moreover, this week at the Dreamforce conference, Salesforce announced they've created tools, including code snippets and API harnesses, to make the Google Visualization API even easier to use. Salesforce customers can now quickly and easily add dashboards and custom reporting applications over their Salesforce data and publish these on any webpage. ISVs and BI firms such as Panorama and Conceptual Clarity, who are already marketing their powerful reporting tools over Google Spreadsheets using the Visualization API, now have access to Salesforce customers. The icing on the cake: since they use the Visualization API, they can address this new market without adding new code to their existing applications.

Seo Master present to you: Google has recently added three important enhancements to our OAuth support:

1. The ability to use OAuth without registration
   
2. Support for software apps installed on a computer or mobile phone
3. Additional controls for our Google Apps Premier and Education customers which allows administrators to give another web application access to a subset of the data Google stores for that organization

Below is an overview of each enhancement, or you can refer to our updated OAuth documentation.

1. The ability to use OAuth without registration

Based on consistent feedback from our developers, we added the ability to use OAuth without having to register the website ahead of time. This change is especially helpful for developers working on test servers that cannot be accessed directly from the Internet.

2. Support for software apps installed on a computer or mobile phone

Many of the larger enterprises that use the Google Apps service choose to run their own login system. They accomplish this by leveraging our support for the SAML protocol which defines a way for Google to redirect the user to the company's login system to be authenticated before accessing their mailbox at Google.  However, in this situation Google normally does not have a password for the user — especially if the enterprise authenticates the user with a password and with a second factor of authentication (such as a token generator they carry on a keychain). Unfortunately, there are many installed software applications created by both Google and ISV developers that use Google's APIs, and those applications are hardcoded to ask a user for their email and password using Google's ClientLogin API. With this new OAuth feature, the software application can now launch a web browser and start a process that both logs the user in through their central SAML login system, and that also gets the user's consent to access their data hosted at Google. Because the user authentication is done in the web browser, it will work with the enterprise's existing login system.  Google is encouraging any ISV that uses the ClientLogin API to add support for this new OAuth flow, enabling usage by the large enterprise customers described above. Google is also planning to enhance our Google Apps Sync for Microsoft Outlook to support this feature such that Outlook can be used with both Google Apps and an enterprise's central login system.

3. Additional controls for our Google Apps Premier and Education customers which allows administrators to give another web application access to a subset of the data Google stores for that organization

This feature for our Google Apps Premier customers enhances our existing OAuth for Google Apps domain administrators, also known as 2-legged OAuth. This feature enables domain administrators to allow specific IT apps or third party web services limited access to user accounts via a centralized permissions system under the control of the  domain administrator. For example, with this new system, an administrator can use the Google Documents API to configure every user in the domain to have a Google Docs folder named "Human Resources" that is automatically populated with common employee forms.  The company might also sign up with an Enterprise SaaS vendor such as Manymoon and specify that Manymoon can access the Google Calendars of all of their users, providing tighter integration with Manymoon's project scheduling features. Previously, this feature required giving the third party vendor access to all of the data that Google stored for that organization, but with this new feature, administrators can limit access to particular data sources (Calendar, Documents, etc). Refer to our documentation for more information.
