Dino Mummy

When you read that title, you probably either thought of a jurassic mother or the next Brendan Fraser movie. No, I’m talking about non-bone remains of dinosaurs. Maybe I just haven’t been paying hard enough attention but it seemed like the sort of news-worthyish item that would blip on my radars. Of course, I’d heard of dino skin impressions but … those were “probable” last time I heard them mentioned.

Images and links …

So here’s a really bad idea…

Build a PC for Linux development work, install two IDE drives and a SCSI controller with one drive and one CD/R. Choose reiserfs for your SCSI drive, to protect your work. You can significantly improve performance by using the entire, raw disk – partition table and all – as a solid reiserfs file system, so make the entire raw disk a solid file system. Bootsector, partition table, everything. Filesystem.

This works, because your Linux calls IDE drives “hdX” and scans them first, and SCSI drives “sdX” because it scans them second.

Now let your Linux update itself to a version that sees all drives as “sdX”. Notice this, and follow the wiki instructions to go on ahead and run grub-install before rebooting. Because, that’ll write a boot loader to the relevant boot drive. You booted of hda, hda becomes sda, so the boot drive should become sda. Read that particular bit of¬†documentation¬†again and be reassured that The Right Thing Will Happen based on the confidence expressed in the wording.

Where will grub write itself? To the bootsector. Where will the bootsector be? Oh, right about the same place your superblock is for the disk-wide filesystem that was previously on sda.

Postscript: Turns out that this bad idea was not so terrible; the reiserfs filesystem recovered, and it was part of a series of careful planning of my filesystems that allowed me to upgrade my box with a minimal disruption. Still. I think in future I’ll take the extra little performance loss and go with a partitioned disk: the performance hit isn’t really that big – an order of magnitude less than, say, running antivirus software.

Uhm, Sofari, So Oddly

I find I’m using Safari on most of my boxes now. I’m not sure why: I am quite happy with IE, I never clicked with Opera and I have a variety of reasons for disliking Firebox.

With Safari under Vista, XP and OS X … I was quite baffled to find there’s no Safari for Linux. Way to reel ’em in, Apple.
