Chrome OS news of GPU acceleration!

email post

GPU acceleration + old drivers = :(

Over the last few months, we’ve made a lot of progress using graphics hardware (commonly referred to as the GPU) to make Chrome faster and more power-efficient. However, as we’ve rolled out features like WebGL and GPU-accelerated HTML5 video, we noticed a troubling trend: users with old graphics drivers experienced a significant increase in crashes when using these features. Because stability is one of Google Chrome’s core principles, we’ve recently become stricter about requiring up-to-date drivers and graphics hardware by adding ranges of old drivers to Google Chrome’s software rendering list.

Developers should continue to ensure that the software-rendered version of their sites work properly for users without GPU-accelerated browsers, so we expect most content to continue to function normally for Google Chrome users with out-of-date drivers -- albeit, without the same performance you might expect from Chrome. WebGL content on out-of-date systems will currently not display, but we are working to provide a software path so that these systems can run basic 3D applications.
As our ability to determine whether a machine can reliably use GPU features improves, we hope to extend hardware acceleration support to more and more users. Here are some steps you can take to maximize the chances that Chrome will run fully hardware-accelerated on your computer:
  1. Use the latest major version of your operating system (such as Windows 7 or Mac OS 10.6)
  2. Install all system updates and driver updates that are available for your system.

Jquery 1.51 is released!

email post

About The Code(Jquery 1.51)

The code itself is written rather cleanly in an attempt to self-document. If you've spotted some areas of code that could be improved, please feel free to discuss it on the Development mailing list. All input is gladly appreciated!
All of the code is available in two formats:

  • Compressed (which allows you to have a significantly smaller file size) and
  • Uncompressed (good for debugging and to understand what is behind the magic).
If you're interested in downloading Plugins developed by jQuery contributors, please visit the Plugins page.
jQuery is provided under the following MIT and GPL licenses.

CDN Hosted jQuery

A number of large enterprises provide hosted copies of jQuery on existing CDN networks that are available for public use. Below are links to the CDN-hosted copies of jQuery that you may hotlink to.

Download jQuery

This is the recommended version of jQuery to use for your application. The code in here should be stable and usable in all modern browsers.
The minified versions, while having a larger file size than the packed versions (note: packed version is not available in current release), are generally the best versions to use on production deployments. The packed versions require non-trivial client-side processing time to uncompress (unpack) the code whereas the minified versions do not. The packed versions of jQuery will take less time to download than the minified or uncompressed versions; however, each time the library is loaded (initially or from the browser cache) it will need to be uncompressed which will cause a non-trivial delay in the execution of any jQuery code each time it is loaded.
