Hi there! I have become a big fan of the 'foreach' package allowing me to do a lot of stuff in parallel. For example, evaluating the function f on all elements in a vector x is easily accomplished: foreach(i=1:length(x),.combine=c) %dopar% f(x[i]) Here the .combine=c option tells foreach to combine output using the c()-function. That is, to return it as a vector. Today I discovered the

Dear all, I would like to ask your help understand the subsequent steps for making my program faster. The following code: Gauslist<-array(data=NA,dim=c(dimx,dimy,dimz)) for (i in c(1:dimz)){ print(sprintf('Creating the %d map',i)); Gauslist[,,i]<-f <- GaussRF(x=x, y=y, model=model, grid=TRUE,param=c(mean,variance,nugget,scale,Whit.alpha)) } creates 100 GaussMaps (each

Hi, I'm using the Umax Astra 610p scanner (parallel port scanner). Unfortunately, it is not supported by sane as Umax is not publishing specs. Searching on google I found out that some people got it working using vmware but nobody could get it working with wine. That is surprising me because people seem to get lots of complicated windows applications working but not a small scanner

Hi, I'm looking for a firewall (preferably on Linux / UNIX) that could automatically block bandwidth abusers as soon as a connection goes over a certain speed, or limit - i.e. either more than say 3Mb/s or 10GB in a giving period (like weekly / monthly). But, I need it to block the IP to, or where the traffic comes from, or goes to. i.e. a user logs into a web server and upload a LOT of

Hi all, I'm just curios and would like some input from the community on this one. We're busy budgeting for a couple of new servers and I thought it would be good to try out the Core i7 CPU's, but see the majority of them don't offer VT-d, but just VT-x. Looking at the LGA1366 range, only the "Intel lga1366 i7 980XE" (from the list of what our suppliers stock) have VT-d,

Hi, 2 websites, hosted on 2 different CentOS 5.7 servers (one being very new, about 3 weeks old) keeps loosing data - but it's more like it's corrupted than being deleted. For example, a photo would be uploaded last night and today when we checked it, it doesn't show on the website. So we check if the file is on the server, and exists but is 0KB in size. Last night it still worked

Hi all I hope anyone can help me with this. I'm trying to get vmware to play along nicely on CentOS 5.1 x64, but I get errors when I try and start a vmx image, or list them.

Hi all I have a CentOS 5.1 x64 server, running Xen version 3.1.0-53.1.21.el5 & Windows 2003 VM. After doing a software update in Windows (via Remote Desktop), I rebooted windows, but it never came back up. So, I logged into the server via SSH, and destoyed the VM, and recrated it. Yet it doesn''t boot up ( I can''t connect to it via RDP). So, how do I debug it to see

Sorry about the previous post, I see the subject had a typo. So here's the correct one :) Does anyone know how to configure Postfix to use SMTP authentication on a relay host? i.e. I have a Linux server, running PostFix on an ADSL line with a dynamic IP. Thus I can't just send out emails from this server but need to relay it via our ISP's SMTP server, which is very unreliable. Now

Hi all If I do a "dig mydomain.co.za" from a Linux server, how do I know which DNS nameserver returns the queries?
