Hi all, I''m working on a sport game that needs a timing system with the following needs: - The game works on a Season basis. So players will be able to see which day of the season today is. - Games will be scheduled according to this Season''s time. - Length of day can be customized. Not necessarily 24h as a normal day. - Administrator can start and restart seasons by specifying

Hi people, Ever since RC 5 (including 1.0) my unit tests that test for inserting duplicate entries fail and throw errors. Each of them implements validate_uniqueness_of to prevent duplicates. While I also put in a ticket for this, I''m wondering if this is actually a defect or maybe intended behaviour afterall. If so, I won''t apply the patch again and look for another

Hi, validate_uniqueness_of has the option :case_sensitive, this option is true by default, there are tests to check that :case_sensitive => false is working, but there isn''t any test to check that, when set to true (the default!), is working, in fact it doesn''t work at. There isn''t a database agnostic way to do a case sensitive search, there is in myql (binary like)

All, Sometimes when I do an rsync, it times out and leaves on orphaned process on the remote machine. I am running rsync over ssh using public key authentication. I synchronize about twenty-five machines, and this problem only appears on one of them. It worked until recently on this machine. I don't know what changed or what is different. I run rsync with a command line like this

To Whomever can assist, I am looking for anyone who has gotten OpenSsh 3.7.1p2 to build under HP-UX 10.20. I am working with the latest gcc (v. 3.3.1), gmake (v. 3.80), and Openssl (0.9.7c) and I still can not get OpenSsh to build properly. It errors out on the build process with a: loginrec.c:1405: dereferencing pointer to incomplete type cing pointer to incomplete type loginrec.c:1514:

I''ve looked at the validates documentation and it appears that validates_uniqueness_of works on only one field at a time. So I can, for example, validate that "sam" is unique to the record set, and that "smith" is unique to the record set. My problem is that each record includes two fields, the _combination_ of which must be unique to the record set, but each of

I have seen several queries about parameterizing the negative binomial scale parameter. This is called the heterogeneous negative binomial. I have written a function called "nbinomial" which is in the msme package on CRAN. Type ?nbinomial to see the help file. The default model is a negative binomial for which the dispersion parameter is directly related to mu, which is how Stata,

Hmmm... I've sent a couple of questions to the list recently, with no responses. Are my messages getting out? Since upgrading to 2.0.2, our Win95 boxes are having problems accessing shares. WinNT works perfectly. Win95 worked fine with 1.whatever, but now it can only see files that are actually in the share directory. It can see subdirectories of the share, but they appear as empty

Hi, I need to install Rmagick to get re-sizing working with Paperclip. My dev machine is on Mac OSX Leopard and the server is on Ubuntu Intrepid 8.1 I dint have Macports or wget at first. I was following this article - http://onrails.org/articles/2007/11/03/installing-rmagick-on-leopard-without-macports-or-fink. Ive done this before too. But some dependency always failed. I want to start with a

Hi I''m trying to create a basic test management tool to organise the manual testing I have to do. I''m working on the results recording module and have a problem. Basically, I want each test result to belong to a test case, a test environment and a build. I want to make sure there''s no duplication of results with these 3 properties. If someone tries to enter a new test

Hello, I am using sm.density() to find the bivariate joint PDFof events: For eg, x<-cbind(rnorm(30),rnorm(30)) den<-sm.density(x) Then I get the joint pdf from den$estimate in order to constructthe joint cumulative PDF. However, summing up all the values from den$estimateisnot equal to 1(have multipliedby the grid size). Anyone could help? Thanks. mc [[alternative HTML version

Hello list. I need help (e.g., a reference, code, package, etc.) in calculating the joint entropy of many variables (some sure highly mutually-informative and some not). Is there anyone here who knows a computationally-efficient solution (such as an R package)? I appreciate you help ... Best, Reza [[alternative HTML version deleted]]

Strange. Both systems are Linux. I compiled the LDAP slave Samba with CFLAGS="-O2 -march=i686" and SuSE's GCC 3.3.1. The fine working master got the same CFLAGS but SuSE's GCC 2.95.3. Without CFLAGS the GCC 3.3.1 works fine too. Didn't know that optimization (and GCC>3) is that dangerous.... Thanks anyway Daniel ------ Hi! We have a replicated LDAP Samba network. I

Dear R-helpers, I have dist class objects for 10 individuals rating the dissimilarities (on a 100-point scale) of the same 10 faces (analogous to the bread data). I would like to get an individual differences scaling jointly for the individual judges and the faces, and plot them on the same axes. This is the example: library(smacof) data(breakfast) res.rect<-smacofRect(breakfast,

Hi I'm trying to maximize a joint likelihood of 2 likelihoods (Likelihood 1 and Likelihood 2) in mle2, where the parameters I estimate in Likelihood 2 go into the likelihood 1. In Likelihood 1 I estimate the vector logN with length 37, and for the Likelihood 2 I measure a vector s of length 8. The values of s in Lieklihood 2 are used in the Likelihood 1. I have 2 questions: ##1 I manage

Dear R users >From what I understand, the joint maximum likelihood procedure for Rasch (availabe in the package MiscPsycho) in R can only be used on binary data. I was wondering if the code is currently being adapted for application to ordinal data? I'm trying to replicate results obtained from Winsteps in R. Best wishes denn -- View this message in context:
