Disable Google Chrome Updates

Tuesday, June 1st, 2010
Google Chrome’s automated update is a double-edged sword. On the plus side, it ensures users have the latest version of the browser: the Chrome 4 update was rolled out to everyone within a matter of weeks. However, many businesses take a more cautious approach. Few are willing to permit large-scale untested software updates, which could cause IT support issues or intranet application failures. IE6’s perseverance within the business world proves that many companies prefer the known risk of an unstable browser over the unknown risk of a shiny modern browser.

Companies that have switched to Chrome are likely to define enterprise-wide policies for updates. Google provide an administrative template for Microsoft Windows Group Policy editor.

Let’s assume you’re developing a web application for a company that uses Chrome 4 throughout its workplace. The last thing you need is Chrome to magically update to version 5 halfway through the development process. Fortunately, it’s possible to disable the automatic update on all operating systems.

Windows

The Group Policy editor may not necessarily be available if you’re disconnected from the company’s network and using Windows XP/Vista Home edition. You must, therefore, tinker with the registry …

Warning:Abandon hope all ye who enter here.
The registry is a dangerous place. You know the drill — neither I or SitePoint accept any responsibility for damage to your PC or your sanity!
Locate HKEY_LOCAL_MACHINE\SOFTWARE\Policies\
Google\Update
Add a new DWORD value named DisableAutoUpdateChecksCheckboxValue and set it to 1 to disable automatic updates or 0 to re-enable them.
Add a new DWORD value named AutoUpdateCheckPeriodMinutes and set a number of minutes; for example, 1440 for once a day, 10080 for once a week, and so on.

Mac OS

Enter the following commands in the Terminal application.

To disable automated updates:

$ defaults write com.google.Keystone.Agent
checkInterval 0
Change the 0 to a 1 to re-enable updates.

To set the update frequency:

$ defaults write com.google.Keystone.Agent
checkInterval
where is the interval in seconds; for example, 86400 for once a day, 604800 for once a week, and so on.

Google Announces New WebM Video Standard, Open-Sources VP8

Monday, May 31st, 2010

by Louis Simoneau

Last Week Google announced WebM, a new web media project that combines the VP8 codec (which Google acquired in its purchase of On2) with the Vorbis audio codec and parts of the Matroska multimedia container. As part of this project Google has open-sourced the VP8 codec, which could have far-reaching consequences for the future of video in HTML5.

The new WebM project has already received support fromMozilla (who has announced that it will be supported along with Theora for HTML5 video in Firefox 4), Opera (who has already released a “Labs” build of its browser with WebM video support), and Adobe (who has confirmed that the VP8 codec will be included in an upcoming release of the Flash player). Microsoft has taken a more nuanced approach, stating that, “In its HTML5 support, IE9 will support playback of H.264 video as well as VP8 video when the user has installed a VP8 codec on Windows.”

Of course, it goes without saying that Google Chrome will be supporting the new format in the near future. A post on the Chromium blog states that preliminary support for WebM is already available in development versions of the browser.
