I know this is quite a handwaving, stupid question, but I don't know where else to ask it and maybe somebody here can at least point me into the right direction, because I'm stuck. I have a program package that were using here (OpenFOAM for those who know it). My problem is that when I compile and link this package on CentOS 5, it won't run on CentOS 4.x-machines but stops with a

I'm running a Samba 3.0.0 server in production in security = ADS mode against a W2k ADS server. Works just fine, thanks! We're sort of under pressure to regrade to a 2003 AD server, which sent me trying stuff out a bit. Meager results. The 3.0.0 I have (linked with MIT krb5-1.2.8) refuses to verify incoming tickets: [2003/10/28 16:27:36, 3]

I've demonstrated a situation people can face right now where it can make a website unusable. Don't handwave away the cost of forcing HTTPS, it adds overhead for all involved parties. Don't get me wrong, I'm all for properly supporting HTTPS everywhere, but it is not without downsides. Joerg

Feature request: please can we have support for messages stored in mbox files, but folders containing both messages and folders. I think this could be done for a folder called e.g. dovecot-list by having an mbox file called dovecot-list and a directory called dovecot-list.folder (or whatever, says he handwaving away name clashes which can be worked around like they are in maildirs). This may

Hi, Is this method broken in R? I am using it to find roots of the following function: f(x) = 2.5*exp(-0.5*(2*0.045 - x)) + 2.5*exp(-0.045) + 2.5*exp(-1.5*x) - 100 It is giving an answer of -38.4762403 which is not even close (f(x) = 2.903809e+25 for x=-38.4762403). The answer should be around 0.01-0.1. This function should converge.. Even for a simple function like f(x) = exp(-x) * x, it gives

Hi based on some code from Thomas Petzoldt, I have a question: --- opar <- par(mfrow = c(2,4)) slices <- 8 m <- matrix(runif(100),10,10) my.list <- list() for (slice in 1:slices) { my.list[[slice]] <- m } for (slice in 1:slices) { x <- 1*(1:25) y <- 1*(1:25) z <- my.list[[slice]] image(list(x = 0:9, y = 0:9, z = z)) } par(opar) #restore device

Hi I have a table with four columns and 3 rows. I calculated the average for each columns as average (A), average (B), average (C) and average (D), then calculate the relative ratio as average (A)/average (B), and average (C)/average (D). I would like to know how can I calculate the significance between the two ratios. Thanks, Meng [[alternative HTML version deleted]]

Peter, the difference between an atomic op and *no* atomic op is huge. And Waiman posted numbers for the optimization. Why do you argue with

There's a third option: try to make virtio-mmio work everywhere (except s390), at least in the long run. This other benefits: it makes minimal hypervisors simpler, I think it'll get rid of the limits on the number of virtio devices in a system....

Hi Folks, as promised, here's what I did to get net rpc vampire working. There's a question at the bottom that someone might be able to answer for me. If the detail below is sane, I'll tidy it up some and submit it as a proper HOWTO. If not, please tell me where I'm being insane :) ====================================================================== Using 'net rpc

...rs will end up using virtio devices via IOMMU by accident? If the answers are both "yes", then x86 is going to be able to use virtio+IOMMU, so PPC looks like the odd one out. Otherwise it looks like we're really going to want to stick with the "ignore IOMMU" rule until (handwave future), and we make an exception for Xen. Cheers, Rusty.

In certain situations sftp download speed can be much less than that of scp. After many days of trying to find the cause finally I found it to be the tcp nagle algorithm, which if turned off with TCP_NODELAY eliminates the problem. Now I see it being discussed back in 2002, but it still unresolved in openssh-4.2 :( Simple solution would be to add a NoDelay option to ssh which sftp would set.
