Google Courgette. Faster, smaller updates for Chrome
If you're a Google Chrome user (on Windows), than you've got googleupdate.exe running - providing silent continuous updates to Chrome as Google releases them (*update* - Google Update actually now works with the Windows Update scheduler - ThnX P Kasting for commenting!).
The only problem is sometimes an update can be a bit large, which is where the new Courgette system comes in. With Courgette, Google is going to pushing down a compressed 'diff' to users. That is instead of an entire new application the diff is the difference between old and new (the delta).
"It is an anathema to us to push out a whole new 10MB update to give you
a ten line security fix," Stephen Adams, Google software engineer wrote in a blog post. "We want smaller updates because it narrows the
window of vulnerability. If the update is a tenth of the size, we can
push ten times as many per unit of bandwidth."
Adams added that means that users can be protected earlier and the smaller update will also work better for users on slower network connections.
That is an astounding level of difference.
