File/Folder Ownership - Cygwin/Rsync - Is it possible to get around rsync taking file ownership?
Case point: 2 Servers (both with Windows Server 2k3 & cygwin). Running ssh on the destination server. Problem: The rsync user will take ownership over any files copied over from the source server. This takes ownership away from the administrators group, thus disallowing inherited permissions. Is there any way around not taking ownership away from the administrators group and giving it to the rsync user? I''ve seen this done with the cwRsync package, but unfortunately our security group will a...

Jobs running too slow
Say I have a job that runs every minute, but it takes longer than a minute to execute. Will it start a new job every minute? If it does, then how would I make a job that sleeps for a certain amount of time, then restarts? I have a job that could take an hour or two to complete, and I don''t want to have multiple copies of that job running a...

Mirror Mirror on the wall, who is the slowest of them all? CentOS
Some of the other RHEL rebuilds take one or two days, while CentOS takes 2 weeks. While i can''t say if they have more than a hundred users, their speed in releasing quarterly updates is commendable. Technically CentOS is not the slowest, as Whitebox takes the wooden spoon but you get the general idea. :) __________________________________________________ Do...

Taking Integral and Optimization using Integrate, Optim and maxNR
Dear All, Hello! I have some questoins in R programming as follows: Question 1- How to take the integral of this function with respect to y, such that x would appear in the output after taking integral. f(x,y)=(0.1766*exp(-exp(y+lnx))*-exp(y+lnx))/(1-exp(-exp(y+lnx))) y in (-6.907,-1.246) It is doable in maple but not in R. At least I could not find the way. p.s: result from maple is:

Why does error_messages_for take string as param?
Hi, I wonder why error_messages_for take strings as params instead of instance variables. error_messages_for ''user'' instead of error_messages_for @user ''user'' is translated into @user eventually. If so, who not take the instance variables directly? Is there any reason for that? Thanks in advance. Sam -- Posted via

Handling Events that don''t take an ID
Hey Kevin, Am I correct in assuming that if I want a particular widget to respond to an event which doesn''t take an ID as an argument (like evt_size or evt_left_down), that I have to inherit a new widget and define the event handler within the inherited class? Here''s a little contrived code example to illustrate what I mean: class MyCtrl < Wx::TextCtrl def

ocfs2console is slow
Ever since we have installed OCFS2, we have had extremely slow performance in the ocfs2console. It can take us over 30 minutes to do the simplest tasks. We do not have this type of performance with other xwindows applications on our server. Does anyone have any performance improvement suggestions for the ocfs2console? Thanks, Reid

Gluster machines slowing down over time
I have 2 gluster servers in replicated mode on EC2 with ~4G RAM CPU and RAM look fine but over time the system becomes sluggish, particularly networking. I notice when sshing into the machine takes ages and running remote commands with capistrano takes longer and longer. Any kernel settings people typically use?

Polychor() - why does it take that long?
Hello. Using the polychor function > polychor(data[c(s1,s2)] ) for polychoric correlations of two ordinal variables in R takes a long time for N=7000 (20 minutes+) and significantly slows down my computer. Now, I have a pretty old computer, but it takes about 20 seconds for MPLUS to print out the complete polychoric correlation matrix for all 16 variables, while I am running the R function only for 2 of the 16 variables....
