I came across a race condition in lightdm greeter setup phase before the login screen is displayed (at boot time or after logout). I reported this also on Launchpad with more details (https://bugs.launchpad.net/lightdm/+bug/1172752), but to work on a proper fix, ideas on how to fix this would be welcome. During greeter setup "lightdm --session-child" is spawned twice. The first call to

Hello-- There must be a better way to do this. I have a class method in my model that finds averages and does a few calculations using find_by_sql. The problem I¹m encountering is that all computed columns from MySQL come back as type string. E.g., def self.find_averages(domain_id) if @@domain_average return @@domain_average else @@domain_average =

I am trying to mirror a file system using rsync. The command I am using is of the form: rsync -a /fs/home/6/ /usr/fs/home/6 /fs/home/6/ is an NFS file system, /usr/fs/home/6 is a local disk. With versions 2.4.6 and 2.4.7pre1, rsync hangs at random places during the building file list phase. I tried with and without -v option(s) and tried breaking the file system down into smaller chunks with no

Hello all, I have been using R for about 3 weeks and I am frustrated by a problem. I have read R in a nutshell, scoured the internet for help but I either am not understanding examples or am missing something completely basic. Here is the problem: I want to plot data that contains dates on the x axis. Then I want to fit a line to the data. I have been unable to do it. This is an example of

I'm trying to create a new column in my data.frame where subjects are categorized depending on values on four other columns. In any other case I would just nest a few ifelse statements, however, in this case i have 4*6*2*3=144 combinations and i get weird 'context overflow' errors. So I wonder if there is a more efficient way of doing this. For illustrational purposes, let's say

ng, I have a matrix (x) with binary content. Each row of the matrix holds exactly one 1, and the rest of the row is zeros. The thing is that I need to 'collapse' the matrix to one column where each row holds the original column index of the 1's (y). Sometimes, the matrix is quite large, so I have a perfomance problem. x <- matrix(c(1,0,0, 0,0,1, 0,1,0, 0,0,1, 0,1,0,

Hi. I''ve been, fruitlessly, trying to extend the login code from the Agile book. What I''m trying to do, is create a list of logged in users. My idea is to the list of sessions. However, many sessions seem to be outdated. I believe the best way would be to get a list of sessions that have been active in, say, the last 15 minutes. Question is: how can I do this? Any hints

CentOS team... as is already bug reported and marked solved... as we await the upstream repair for this. It was reported that this was happening on CentOS 5.

Hi, A small (but annoying) problem with RMySQL library. When a connection is closed, it echoes 'TRUE' to the console. Like this: R> mysqlCloseConnection(con) [1] TRUE The real problem comes when I use RMySQL with Sweave, since the TRUE echo gets into my final Sweave document. Even when I explicitly state <<include=FALSE, echo=FALSE>>= in the header of the R code chunk.

Hi, I've set up a very simple R repository. Just a single source library. Everything works fine. I can install the package on my client using: install.packages(repos='http://www.myServer.se/myRepo/', pkgs='myLib', dep=TRUE) However, I want to protect the repo, so I use a .htaccess, placed directly under 'myRepo' on the server. I use 'Authentication Basic' and

I'm trying to dynamically build variable names to use on a list. Let's say I have a list like this one: l <- list(V1_1=c(1,2,3), V1_2=c('One','Two','Three')) And I succesfully build my variable name like this: paste('l$', 'V1_1', sep='') Why can't I just run a mean call with the pasted variable name? mean(paste('l$',
