packet loss on ixgbe using vlans and ipv6
...ny packets loss. If
I do not use vlans, I don't see packet loss with ipv6 either.

Logic with regexps
...ch match
## rex1 AND do not match rex1:
X <- c(
"abcdefg", # Yes
"abchijk", # No
"mnopqrs", # No
"ijkpqrs", # No
"abcpqrs" ) # Yes
rex1 <- "abc"
rex2 <- "ijk"
ix1<- grep(rex1,X)
ix2<- grep(rex2,X)
X[ix1[!(ix1 %in% ix2)]]
## [1] "abcdefg" "abcpqrs"
Question: is there a way to construct 'rex' from 'rex1' and 'rex2'
such that
X[grep(rex,X)]
would given the same result?
I've not managed to find anything helpful in desciption...

efficiently diff two data frames
Dear all,
What is the quickest and most efficient way to diff two data frames,
so as to obtain a vector of indices (or logical) for rows/columns that
differ in the two data frames? For example,
> Xe <- head(mtcars)
> Xf <- head(mtcars)
> Xf[2:4,3:5] <- 55
> all.equal(Xe, Xf)

Subsetting a matrix
I'd welcome some comments or advice regarding the situation described
below.
The following illustrates what seems to me to be an inconsistency
in the behaviour of matrix subsetting:
> Z<-matrix(c(1.1,2.1,3.1,1.2,2.2,3.2,1.3,2.3,3.3),nrow=3)
> Z
[,1] [,2] [,3]
[1,] 1.1 1.2 1.3
[2,] 2.1 2.2 2.3
[3,] 3.1 3.2 3.3
> dim(Z)
[1] 3 3

Salvage or undelete files of damaged ext2/ext3 file systems
...be useful if you have accidently remoded a lot of files in
a ext2/ext3 file system like with a "rm -rf /" command, or if you
accidently reformatted the file system via an mkfs/mke2fs command, or if
your harddisk had severe hardware problems. The filenames will be "ix1-"
or "ix2-" followed by the block number of the indirect or double
indirect block number that defined the main part of the file. In this
way salvage may be used to repair, rescue, recover or undelete files.
If a file already exists in the current directory, and is not writable,
salvage will skip writin...

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL
