Re: ext3 / ext4 on USB flash drive?
>From the little I have heard about control systems for cars, which was
some years ago, they were blockhead proprietary. The analogy would
only work if computing was customarily blackbox technology, which it

contained less than their advertised amount of storage.

(Novice-) Problem with the plot-function
Hello,
i have written this little function to draw different normal distributions:
n.Plot <- function(x,my,sigma) {
e <- exp(1)
names(x) <- x
f.x <- (1/(sigma*sqrt(2*pi)))*e^(-1*(((x-my)^2)/2*(sigma^2)))
plot(f.x,type="l",xlim=c(-5,5))
return(f.x)
}
if i define x like this:
x <- seq(-5,5,0.01)
Now
n.Plot(x,0,1)
DOES draw the correct plot, but the x-axis is labeled

Xen 4.1.1 packaging enhancement
Hi,
This email is mainly addressed at Waldi (Bastian Blank). I'm resending it
since the previous one is waiting for approval due to its size being
bigger than 40k (I compressed the .diff this time, so it should be ok).
I have worked on enhancing the current packaging of Xen 4.1.1 over the
last weeks. The main goal was to package the OCaml libraries of Xen as
separated binary packages, and
