Tech Note For Self.

Apr. 25th, 2007 | 10:30 am

I decided to build a new computer recently, and I thought I'd throw down some notes on the little tricks to getting Debian Etch running on it.

The Motherboard is an Intel DP965LTCK. I had initially intended to pick up a SATA DVD drive, but when I ordered, I forgot about it. By some reversal of luck, the SATA controller was recognized by default and the IDE chipset was not, so I couldn't get enough of the install started from the boot iso.

The Fix:

Set the SATA controller to AHCI in the bios, and boot the install kernel with generic.all_generic_ide=1. If you don't set AHCI, the disk drives get picked up by this as well and they don't run so well. Windows XP will not boot with AHCI set, but after getting gnu/linux (take that Richard Stallman, I lower-cased your recursive acronym) installed, you can toggle it off and everything will be honky dory.

Apparently getting a really new video card means that I get to use the beta nvidia drivers and have to wait a little while for the GPGPU support to happen.

This sucker should last me 6 years, just like the last one.

Apparently Richard Stallman is giving a talk in my building at 10am next wednesday. Wacky.

I asked some of my relatives what they might want for christmas and they indicated that a donation to charity would be nice.

I just realized that the EFF meets the charity requirement, and it is something that I care about.

Thought I'd point that out to anyone else looking for charities you can donate to.

Man, I was digging around for blackbox themes on freshmeat today and sooo many of them involve naked women. I want pretty worksafe themes. It is a shame that using a geeky window manager means that other geeky people use it and therefore very few people resembling decent graphic artists are making themes.

In other news: null pointer dereferences in kernel makes baby john cry -- more specifically it reboots the machine. Time to use the magic number dance to get it initialized properly (p2m[((*store_mfn << 20) >> PAGE_SHIFT) - 1] where p2m is a map from PFN to MFN, store_mfn is a pointer to a known address, and PAGE_SHIFT is architecture dependent). Yumm.

Because laughing out loud in a room full of quiet people makes it even funnier.

Dear Lazyweb::Math,

At lunch today we were discussing the assignment of a ranking (1-10) to objects and we were trying to come up with a different system that might take into account more than a simple one dimensional scale. What we are wondering is whether, given the results of a number of queries to an individual of whether Object A is better than Object B for all of the objects, we can construct an n-dimensional space in which there is a partial order in each dimension even though we might have a non-transitive set within the queries (a > b, b > c, c > a). The difficulty being that we have no idea what the dimensions are and that the comparison operator is subjective. The main goal is to see what these dimensions might be and what we might be able to attribute to each of them.

This doesn't necessarily require dimensions, but sets with a partial-ordering.

Is this doable? Are we full of crap? Did I do a horrible job explaining?

Apologies if I butchered the math terminology.

Because you can't get on the southbound 805 down here....


If you remove the @blahblah stuff it does something more reasonable.

I got this by searching for San Remo Dr, Corona, CA 92882
then using "To Here" from 92122.
