MBP: Distorted Video Problem

MBP: Distorted Video Problem

[18 July 2009]

And so it happened to me… On a Saturday morning, I am the latest victim of the Macbook Pro Early 2008 bug. Apparently, according to Apple, it is a problem with NVIDIA GeForce 8600M GT graphics processor. In my case, it is more than a distorted video. Upon bootup, it shows these distorted lines at first, tries to load the OS, then stops with Apple’s own version ofย  BSD (Black Screen of Death i call it) [see screenshots below]. Logic board fail.

The Apple Support website has THIS explanation:

Symptoms
In July 2008, NVIDIA publicly acknowledged a higher than normal failure rate for some of their graphics processors due to a packaging defect. At that same time, NVIDIA assured Apple that Mac computers with these graphics processors were not affected. However, after an Apple-led investigation, Apple has determined that some MacBook Pro computers with the NVIDIA GeForce 8600M GT graphics processor may be affected. If the NVIDIA graphics processor in your MacBook Pro has failed, or fails within three years of the original date of purchase, a repair will be done free of charge, even if your MacBook Pro is out of warranty.

Resolution
Apple is issuing refunds to customers who may have paid for repairs related to this issue. Please contact Apple for details on the refund process.

IPv6 in 30 Minutes

IPv6 in 30 Minutes

If you were inspired to implement DNSSEC through the presentation “DNSSEC in 6 Minutes” by Alan Kegg (ISC), today I found the IPv6 version!

As I was running through the archives of the latest NANOG meeting, I chanced upon this catchy topic.ย  The title of the presentation Deploy a Production IPv6 Network in 30 Minutes or less (or it’s free) by Richard A Steenbergen looks very promising…

Forgive the premature post. I have to go watch the talk first (then maybe implement on a test environment) before I can really say anything. I’m hoping it can convince more people to migrate to IPv6 soon. ๐Ÿ™‚

It uses NSEC3, which is only fully-supported in Bind 9.6.1 and up.
