And of course there's always the old standby in /etc/passwd (obviously change the account name) secretshutdown:x:0:0:root:/root:/sbin/shutdown And it presupposes that root logins are allowed (which is asking for trouble). >>>Ericw

Howdy, I''m new to rails and I''m learning form Agile Web Dev with Rails. It seems all of the examples that use form_tag use it in situations where the action first creates a new object before doing a request.post... If I''m in a situation where I''m managing Roles, Rights, and assignments of rights to roles, I may want to have one little form with a text field and

Dear all, I am looking at habituation of dogs trotting on a treadmill. I record the ground reaction force and I analyze it with several discrete variables (maximum, minimum,...) For each variable, I get between 40 and 50 data per sample. I record data at time 1 min, 2 min, and 4 min a day, and I have 4 days of measurement (one day a week). That means I have 12 samples : Day1_Min1, Day1_Min2,

...tistics (creating distance matrices, manipulating graphs for pretty figures, etc). I'm working through Bolker's Ecological Models and Data in R (which is a great book for ecologists/life sciences types who want to learn how to just barely get by in R, with know previous knowledge of R code presupposed). My advisor wants me to explore odfWeave to stream-line my notes. This is important because I will inevitably be his TA in his R stat course, and I will need to be proficient with the software. So far I have been copy-pasting my codes into a word processor (both open office and word) and inserting...

Hi, I was thinking about the difficulties and complexities of using chroot in scp or sftp-server, in order to limit the user in which files they can access. I've seen a lot of arguments about how it is pointless to try and secure scp or sftp (also from a logging perspective) because if we allow SSH access, the user can simply provide their own scp or sftp binary, that does not do the

Hi Justin, Thanks for bringing this up, I think it's important to discuss these issues here.

Great, just looking to confirm that there is no "official" support site; Has anyone one tried using digital rapids hardware(cards appliances) to feed live video / audio to an icecast server?

I am still trying to get used to R, and apparently haven't found the right place in the documentation to see how to do what I want in R. If I were to do this in C++, there'd be no problem: I'd write it all myself, but I want to learn R well enough it can save me a lot of coding time. Here is the first task I set for myself. I have a datasource (a vector of values). I want to

Hi there, Just wondering if anyone has any tips for using arrays? I am trying to convert the following SAS code to R: data A2; set A1; by subject_id; retain BX1-BX10 i; array b(1:10) BX1-BX10 ; if first.subject_id then do ; do j=1 to 10; b(j) = .; end; i=1; end; b(i) = BX; i = i+1; if last.subject_id then

There is a new updated kernel for centos 3.1 that fixes a security issue. As I have not had time to test this build I am releasing it for testing for 24 hours to pick up any problems before general release. It is available at :- http://caos2.caosity.org:/centos/3.1/updates/i386/RPMS/ The version is 2.4.21-15.0.2.el.c0 Please install and test these packages, they are as yet unsigned and not

I have a need to use the unsupported kernel for one feature only (AFP/Appletalk support). Never having had to use it before, I''m unsure of what''s all in it other than reading it''s config file. From those that do use it -- is it considered stable enough to use in lightweight production? I''m debating the use of it versus wasting my time rebuilding the normal

Hepp! I am sitting in a remote country trying to reboot my server at home. Services are running, but the filesystem seems to be unreachable. I can ssh into the system, but when entering interactive mode, nothing happens and the session is terminated. Then I thought - what if sshd had builtins like bash, so that i could send a "reboot" command to the ssh daemon instead "ssh system

I am trying to install the rgdal package on my Mac OS X 3.9. I downloaded and installed the GDAL libraries from Fink and then tried to install rgdal and got the following message. I tried to determine if the GDAL libraries were in my path but I'm not sure how to do that. Any ideas? Thanks. trying URL 'http://www.biometrics.mtu.edu/CRAN/src/contrib/rgdal_0.4-10.tar.gz'

There is a warning in the documentation for ?factor (R version 2.3.0) as follows: " The interpretation of a factor depends on both the codes and the '"levels"' attribute. Be careful only to compare factors with the same set of levels (in the same order). In particular, 'as.numeric' applied to a factor is meaningless, and may happen by implicit coercion.

Hi, I have matrix of sea bottom depths that I am plotting in R with the function 'image'. I am particularly interested in the 200m depth contour (I'm using 'distance from this feature' as a covariate in a model) and would like to extract the data at evenly spaced points along it. I can easily superimpose a line at 200m using the function 'contour'. What I want to

Probability <- function(N, f, m, b, x, t) { #N is the number of lymph nodes #f is the fraction of Dendritic cells (in the correct node) that have the antigen #m is the number of time steps #b is the starting position (somewhere in the node or somewhere in the gap between nodes.
