Delta RPMs is a bandwidth saver. Instead of downloading full rpm files on updates, delta rpms (.drpm) hold only the changes in binary form. The size of the packages is now significantly reduced thus saving bandwidth. Once downloaded the drpm file get reconstructed to form the full package before they gets applied. On avg I see 70% bandwidth savings after moving to Presto.
Presto is the Fedora project to enable delta rpms on all Fedora repositories. Fedora 11 is Presto enabled.
I’ll walk you through setting presto up.
1. Search your repos to make sure the yum-presto package is available.
[root@bamboo]# yum search yum-presto
2. Install the yum-presto package.
[root@bamboo]# yum install yum-presto
3. Try running an update to see presto in action.
[root@bamboo]# yum -y update
Finishing rebuild of rpms, from deltarpms
<delta rebuild> | 79 MB 01:14
Presto reduced the updates to 33 M from 79 M which is a 59% savings.

Almost all corporate users today use notebooks at work. The “Lenovo ThinkPad” is a favorite choice. Why? I don’t know. I at my work place we are all on Lenovo ThinkPads.
Earlier this week Lenovo issued a battery recall program for it’s ThinkPad R60, R61, T60, T61, X60 and X61 series. The faulty batteries either held only minimum charge or completely stop functioning. Lenovo has come back to ensure the faulty batteries don’t pose any risk to the end users.
To check if your battery falls into the bad battery list, head on over to Lenovo’s battery recall page. Download and run the Battery Diagnostic Tool to check your battery model, if compromised you will be redirected to another page to initiate the replacement process.
The PS3 slim is almost here. I’ts coming out in September and prices at USD 299.
It’s slim, has a tough looking black finish, weighs in at 7.05lb and comes standard with a 120GB hard disk. All squeezed into the new slim form factor.
Check out the PS3 Slim intro by Sony’s Jack Tretton.
Here’s a comparison chart I pulled off engadget.
I’m not sure, I’ve go a white PS3 at home and somehow feel it looks better then slim. Well, I’ve only seen photos of the PS3 Slim so far, might just change my mind when I actually get to see one up close and personal.
Anyone know when we can expect to see the PS3 Slim in Malaysia?
