If you’re planning on running Oracle VM with Amazon EC2, there are some important limitations you should know about. As part of my work getting the Oracle Linux Unbreakable Enterprise Kernel 2 working (yeah that’s a mouthful) I tried using the Oracle-supplied Oracle Linux 6 AMI images that are listed as community AMIs by Amazon: [...]

As announced a few days ago, Oracle’s core database product is now supported on Oracle Linux 6. Coming a full 13 months after Oracle Linux 6′s launch, and 16 months after Red Hat Enterprise Linux 6, it’s a much anticipated announcement. Update 28-Mar-12: the official certification information has come out on My Oracle Support. So [...]

The official Debian kernel building tools are a thing of wonder. But, it didn’t do what I wanted, which was to build the exact version of the kernel that I’m running. I guess it is only ever used to build the latest version.
Here is the best documentation I found for this task. It refers to this which is also pretty good.
Also, reportbug failed (it was unable to get the list of open bugs for this package from the Bug Tracking System) — I used debian-bug in debian-el package (as noted at the bottom of this page). To actually send the mail, use ctrl-c ctrl-s in the mail buffer (or ctrl-c ctrl-c if you want to send the email and exit emacs).
UPDATE:
Maybe I misunderstood … maybe the -5 is not the patch level I’m aiming for. We shall see.
UPDATE:
No, the -5 is the “ABI” level, and has nothing to do with the Debian patch level. So there was no bug. I was supposed to build with all the patches. Live and learn …

If you're trying to do post-mortem analysis on a crashed river, or trying to find kernel-level
bottlenecks with oprofile, you need the decompressed kernel w/ debug symbols. This comes in a
form of a vmlinux file. Some distributions ship debuginfo packages, namely RHEL. On Ubuntu
this seems lacking.

I will be running another Linux Kernel Walkthrough for OCLUG at TheCodeFactory next week. This time the topic is "booting".
I am frantically preparing slides using (slightly modified) Rusty's svg to png presentation scripts. The svg's are naturally created in Inkscape, and the png's are useful because I can display them in a regular image viewer like gqview. I'll write more on this later.

Here is the same video on google/video... it's a lot lower rez :(

I will be kicking off a new series of talks at OCLUG later this month. The idea is not mine, but a copy of a similar series ran by Silicon Valley Linux Users Group. Kudos to them!
Here is the info on the first Kernel Walkthrough: Source Tree Layout. I will start off by covering the tree structure and talk a bit about the components, before handing control of the talk over to the audience and let them drive the types of things they would like to explore.
We are being hosted by the TheCodeFactory, which is a very cool concept. From the website:
"TheCodeFactory is a collaborative work space located in downtown Ottawa at 246 Queen Street, between Bank and Kent, above the Green Papaya Restaurant. TheCodeFactory is a clubhouse or water cooler for the Start-up community in Ottawa."
In short they are a place where startups can meet and collaborate way before they have any office space of their own. Ottawa being such a hotspot for startups, this is clearly a good idea.
