Hi, I have a Dell T710 with 4 X 10G ethernet interfaces (2 X Dual port Intel 82599 cards). It is running FreeBSD RELENG_8 last updated on July 13. What I see is packet loss (0 - 40%) on IPv6 packets in vlans, when the machine is not the originator of the packets. Let me try to describe a little more. If a neigbouring machine ping6 it, there will be packet loss. If it act as a router for ipv6,

Dear R'sians, Would really appreciate if you could suggest a more efficient way to order the columns of a dataset. The column names of the dataset contain indices separated by a period. Following are examples of my code and the dataset. oC <- function(tg=x2) { lth <- length(grep("T",names(tg))) thix <-

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 >

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) [1] "Component 3: Mean relative difference: 0.6863118" [2] "Component 4: Mean relative

Hi list, since we activated 10gbe on ixgbe cards + jumbo frames(9k) on 9.0 and now on 9.1 we recognize that after a random period of time, sometimes a week, sometimes only a day, the system doesn't send any packets out. The phenomenon is that you can't login via ssh, nfs and istgt is not operative. Yet you can login on the console and execute commands. A clean shutdown isn't possible

Hi Folks, Thanks to several people's suggestions and clarifications, I think I have implemented a function which computes the conditional mean and covariance matrix of a subset of the dimensions of an MV-normal variable, given the values on the other dimensions (these conditioning value can be presented as a matrix, to deal with several cases at once). The code is below, for anyone who would

hi, I have a hard time figuring this out, the kernel says: ... ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.5.15> port 0xecc0-0xecdf mem 0xd9e80000-0xd9efffff,0xd9ff8000-0xd9ffbfff irq 40 at device 0.0 on pci4 ix0: Using MSIX interrupts with 9 vectors ix0: Ethernet address: 90:e2:ba:29:c0:54 ix0: PCI Express Bus: Speed 5.0GT/s Width x8 ix1: <Intel(R) PRO/10GbE

I finally got a 10G card that is recognized by FreeBSD (9.1-stable): ... ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.4.8> port 0xecc0-0xecdf mem 0xd9e80000-0xd9efffff,0xd9ff8000-0xd9ffbfff irq 40 at device 0.0 on pci4 ix0: Using MSIX interrupts with 9 vectors ix0: RX Descriptors exceed system mbuf max, using default instead! ix0: Ethernet address: 90:e2:ba:29:c0:54

Hi, I'm trying to read a subset of a netcdf file into R, but although I'm relatively experienced using R, I'm still new to netCDF files, so this may be a very simple/stupid question! I've included an example of the type of file I'm looking at here. www.met.reading.ac.uk/~swp06hg/ccd1983_01-dk1_20.nc (~7Mb) It's a 2D array of the variable CCD along with its lat and

Hi In a dataset I have length and age for cod. The age, however, is ony given for 40-100% of the fish. What I need to do is to fill inn the NAs in a correct way, so that age has a value for each length. This is to be done for each sample seperately (there are 324 samples), meaning the NAs for sampleno 1 shall be calculated from the known values from sampleno 1. As for example length 55 cm

Hello List, I'm a very new user to the R system. I'm only beginning to learn the basics, but so far I've been able to do little more than try a few examples, and of course begin reading the documentation. My primary motivation for exploring R is the availability of tools like the 'spdep' package for calculating spatial statistics such as Geary's C and Moran's

Hi! I have made some extensions to debugfs to undelete or recover files from a damaged ext3 file system. Salvage or undelete files of damaged ext2/ext3 file systems debugfs salvage command can be used to salvage files from a damaged ext3 or ext2 file system. The code is alpha, so use at your own risk. the usage is: salvage first-block count-blocks Salvage tries to salvage files found in

I am looking for online courses to learn Spatial Statistics using R. Statistics.com is offering an online course in December on the same topic but that schedule doesn't suit mine. Are there any other similar modes for learning spatial statistics using R??? Can someone please advice??? Thank you. Ravi -- View this message in context:

Hi there We have a pair of servers running FreeBSD 9.1-RC3 that act as transparent layer 7 loadbalancer (relayd) and pop/imap proxy (dovecot). Only one of them is active at a given time, it's a failover setup. From time to time the active one gets in a state in which the 'thread taskq' thread uses up 100% of one cpu on its own, like here: ---- PID USERNAME PRI NICE SIZE

Hi, I'm having some trouble with matching. The regexp in my dovecot.sieve file should match on email addresses, but does not. # The code: if header :matches "From" "<[a-z0-9-]*@[a-z0-9-.]*>" { set "sender" "${1}"; } if not execute "grepfrom" ["${sender}"] { if envelope :matches "from" "*" { set

Hello does R support [:punct:] in regular expressions? I am trying to strip all regular expressions for a vector of strings. > x <- c("yoda-yoda","billy!") > gsub("/[:punct:]/","",x) [1] "yoda-yoda" "billy!"

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 Checking
