integrate with large parameters
Dear R-users,
i have to integrate the following function
`fun1` <- function (a, l1, l2)
{
exp(log(l1) * (a - 1) - l2 * lgamma(a))
}
but if l1 is large, i get the "non-finite function value" error, so my
idea is to rescale with exp(-l1)
`fun2` <- function (a, l1, l2)
{
exp(log(l1) * (a - 1) - l2 * lgamma(a) - l1)
}
but it seems this doesn't solve the problem,...

Y <- lapply(X,function(x) sample(x, round(runif(1, min=10, max=50))))
X and Y are both lists, and I've made the following function to work on that data as part of a simulation I'm building:
Mutate<-function(x){
l<-0
for(i in x){
l2<-0
l<-l+1
for(i in x[[l]]){
l2<-l2+1
if(runif(1) < 0.9) ifelse(runif(1) <0.5, x[[l]][l2] <- x[[l]][l2]+1, x[[l]][l2] <- x[[l]][l2]-1)
}
}

}
I call this with Effectors<-Mutate(X)

nut-2.2.1-pre2
Shamelessly reusing the announcement Arnaud sent about three months ago
for nut-2.2.1:
"We're preparing to release 2.2.1-pre2, so if you have some fixes to
backport on Testing, consider announcing it and doing asap.
As always, compatibilities update and bugfixes only!"

How to set QEMU qcow2 l2-cache-size using libvirt xml?
QEMU's default qcow2 L2 cache size is too small for large images (and small cluster sizes), resulting in very bad performance.

Because .L3 and .L2 are in different sections.

[LLVMdev] indirectbr and phi instructions
Hi,
How does the requirement that phi instructions have one value per
predecessor basic block interact with indirectbr instructions? For
instance, take the following code:
L1:
br i1 %somevalue, label %L2, label %L3
L2:
%ret1 = i8* blockaddress(@myfunction, %L5)
br label %L4
L3:
%ret2 = i8* blockaddress(@myfunction, %L6)
br label %L4
L4:
%ret = phi i8* [%ret1, L2], [%ret2, L3]
indirectbr i8* %ret, [label %L5, label %L6]
L5:
%myval = phi i32 [0, %L2], [1, %L3] ; are both of these...

Layer 3 switching...
Is it even possible or even worth while to do layer 3 switching
(bridging) on a Linux system?
Or would this be considered routing even though everything is done on
OSI Layer 2?
Which would be faster, Layer 3 switching (bridging) on OSI Layer 2 or
routing on OSI Layer 3?

I haven't done any v2v conversions in L2 (or at any other level).

that wasn't intended. Rich, you bounce them here, if you prefer (instead

Re: Double fault panic in L2 upon v2v conversion
Hi,
We all agree that it's not specific to virt-v2v.
I managed to reproduce the same double fault on "normal" L2 boot - without
libguestfs interference.
And as Paolo wrote already, he will take a look at it.
Thanks,
