Google has shrink-wrapped the way it delivers updates to its Google Chrome browser by releasing a new system dubbed Courgette. Mountain View wonks decided to tweak the way it automatically sends out code to Chrome, after finding that some of the updates were slowing down Windows-based computers, as well as making them more open …
Could this courgette perchance be used maliciously to inject some ownage into the shiny Chrome? It all sounds a bit low-level for my liking. On the other hand, if I just don't know what I'm talking about, then top marks for use of brains.
Are you listening, Sun? I mean, Oracle.
Well, that seems like a pretty self-evident and also pretty good idea. I hope they also though about checking the hashsums of the re-generated binaries after the fact and we are on a roll.
Courgette? WTF do these people smoke. Been using to much Humping Hippo OS's if you ask me...
Are you listening, Apple?
Stop making me redownload iTunes and the entire iPhone OS every time you update them!
The principle of Delta files isn't new
SuSE Linux began this method of updates back in version 9.3: post-update checksums, the works. I haven't used a SuSE server in about a year, but I'd like to know how this approach reduces the overhead on the machine doing the update. Using Delta RPMs in YaST actually increased the load on the CPUs quite considerably during an update. The use of Deltas was actually set as a user-definable option for this reason. Even so, I'd guess a brief increase in workload is preferable to an increase in bandwidth, since the ability of machines to handle workload is still expanding a lot faster than our badwidth is.
Maybe it'll start that way but introduce the possbility of your machine becoming "Like a cat tied to a stick that's driven into frozen winter shit"
As found in Firefox
That is all.
AMD/ATI please take note...
When I decide to update my video drivers I would like a way to download the drivers and the control centre without the Microsoft C++ runtime environment stuff! I got that last time, it hasn't changed!
And no I don't want the freebie apps from one of your partners, I never choose to install them, I just wish I didn't have to download them in the first place!
The new age of naming
I bet you (the author, not the internet at large that may cost a lot of money.) £0.50 that in 10 years names like "microsoft live office 3000" are back in fashion.
Take note MS
Another reason to love Google.
Re: Take note MS
I think they already have. They've been only patching the bit wot needs it since Jesus was a lad, but then they designed their patch update system when the world was on dialup and keeping traffic to a minimum was bloody important upfront, rather than something you could tack on as an afterthought.
Re: Take note MS
The generic term for this is differential compression, only sending the differences between a file and the updated version. Microsoft (Windows Update) and Novell/SuSE (delta RPMs) have been doing it for years.
What Google have discovered is a better differential compression algorythm, not the technique itself. Now if only Ubuntu, Red Hat and Debian would take note.
