Creating/Protecting a Subnet
I have an admin machine, and a backup server which does backups. The backup server has IPMI so I can do lights-out admin, and I want to allow this from the admin machine only. IPMI is completely unfirewalled, and so it must have a different class C than working networks.... this is just how it is. I''ve set the IPMI IP on the backup server to 192.168.10.4, and created a virtual

force b/w printing
Has anyone an idea, how to force users to print b/w on a color printer. We are in the process to deploy color printers to some of our offices where they use centos 5.5 as their OS. They need the printers to print some advertisement material. But for everything else, they don't need it. And because of the costs of the color printing we would like to force them to use B/W where not explicitly

7110 questions
Hi all, (down to the wire here on EDU grant pricing :) i''m looking at buying a pair of 7110''s in the EDU grant sale. The price is sure right. I''d use them in a mirrored, cold-failover config. I''d primarily be using them to serve a vmware cluster; the current config is two standalone ESX servers with local storage, 450G of SAS RAID10 each. the 7110 price

Change Function based on ifelse() condtion
The reason that it works for Apply_MC=TRUE is that in that case you call mclapply(X,FUN,...) and the mclapply() function strips off the mc.cores argument from the "..." list before calling FUN, so FUN is being called with zero arguments, exactly as it is declared. A quick workaround is to change the line Lapply_me(as.list(1:4), function(xx) { to Lapply_me(as.list(1:4),

A question on Programming
Dear all. Let say I have a group of codes which will be used in many places in my overall R-code files. These group of codes will be used within a for-loop (with a big length, like 10000 times) and also many other places outside of that for loop. As this group of codes are being used in many places, I thought to put them within a user-defined function. Here my question is, is there any speed

Question on Round function
I happened to see these: > round(.5, 0) [1] 0 > round(1.5, 0) [1] 2 > round(2.5, 0) [1] 2 > round(3.5, 0) [1] 4 > round(4.5, 0) [1] 4 What is the rule here? Should not round(.5, 0) = 1, round(2.5, 0) = 3 etc? Thanks and regards,
