Thoughts about the command line

Posted 03-29-2009 at 02:36 AM by bitpicker (Bitpicker's Blog: Random musings and rants)

The following started out as a comment to this blog entry by Carla Schroder on But it quickly became too long so I decided to simply post it here.

Any interface is a metaphor for what you're really doing: shifting zeroes and ones around. Absolutely everything you ever do on the computer is just a metaphor, whether it's using a GUI, the CLI or even programming.

I have a pc clone with an lfs version6.3 os that was builded from a live CD. It got on the internet
today with Lynx (27mar09). Surprise! Surprise! Thanks to all involved from various time periods and
various places on the internet. Large and small this and thats from HoWTO's and tutorials and forums
and e-books. lfs is very cool.

A few years ago my computer quit booting from it's non-linux system and has been in disuse. Almost
gave it away once. Glad...

Dell has historically had a pretty low-end line of RAID cards (the PowerEdge Expandable RAID Controller, or PERC for short) that have required tons of time and care to get them operating at a reasonable level. This blog post will cover my experiences with the PERC6/E line of cards (which aren't that bad, especially compared to previous versions) and how to get optimal performance out of them on Dell 1950/2950 machines, as well as PostgreSQL general configuration.
