RAID etc

On a closed mailing list someone wrote: 2 X 120gb ide drives installed as slaves on each ide channels. … Presto. A 230’ish GB storage NAS for all my junk.

I’m not going to write a long technical response on a closed list so I’ll blog about it instead.

Firstly I wonder whether by “junk” […]

root-kits on robots

This story on 365tomorrows.com on the topic of rootkits is interesting (note the OSs involved). Also it made me wonder about the other possibilities for a root-kitted robot, the mind boggles at how it might determine whether you need an enlargement to some body part…

wasted votes

In a mailing list to which I subscribe there is currently a discussion on US politics with the inevitable discussion of wasted votes. As I don’t want to waste my writing on this topic on a closed list I’m posting to my blog.

There is ongoing discussion on the topic of wasted votes. As a […]
