Hi, Dear all, I am just starting using R in my work and got some trouble to figure out some of the errors. Can anybody help me? The following is the script: read.csv('pupil.txt',header=TRUE,sep='\t')->pupil samp<-c(1:50, 112:162, 171:220, 228:278) pupil.nn2 <- nnet(Type ~ ., data = pupil, subset = samp, size = 2, rang = 0.1, decay = 5e-4, maxit = 200)

Hi. I thought that BackgrounDrb was the perfect solution for my long running report production tasks. But I can''t seem to get anything useful back out of it. I set up a simple test worker that just does class TestWorker < BackgrounDRb::Rails attr_reader :pupil def do_work(args) @progress=0 @pupil=Pupil.find(3) sleep rand*10 @progress=100 end when I try to

In my tests, I use fixtures, eg pupils.yml might be: jimmy: id: 100003 known_as: Jimmy surname: Page academic_year_id: 1 gender: m In the test, @jimmy (the referencing style referred to in Agile Web Dev....) is nil, whereas pupil(:jimmy) returns the expected Pupil object. What gives? Robert

...ing to accomplish Say that I have a Pupil model . Perhaps also a Teacher, Course models. Teachers will have things called Course_Offerings. To keep track of a pupil’s performance in a course there will be a separate model called Course_performances. These course_performances will belong to both Pupils and to Course_offerings. In addition to foreign keys, I’d like the course_performance records to have their own copy of the Pupils "full_name" for easy access in views. Given a list of Pupils, is the code below an efficient way of creating a course_performance instance and associating...

Doea anyone know how to compute components of variance analysis? For example, I have the score of pupils on a test. Each pupil belongs to a school and within each school I may have several classes? How can I estimate the variance of the pupils, schools, classes and the errror variance? Any examples? Any help will be appreciated.

Hallo, i've got a little question: is it possible to query the domain controller which user is loggid in from which workstation. I'm writing an webapp for teachers; it would be nice to know which pupil logged on from which workstation to shutdown the correkt workstation in order to kick the pupil (force logoff) or is there an other way to

.../etc/samba/smb.conf. Obviously some tweaks were made to the Samba config to deal with changes in the LDAP DB organisation (users in a different OU, etc.), but share definitions were kept intact. What's going wrong is this: shares that *should* be being automapped for members of the "CSSG Pupils" and "Technology" groups are not being automapped. Other shares, that all users get via logon.kix, are mapped. the logon script is definitely being run - one can watch it execute when a user logs on. It's not a rights issue - members of "CSSG Pupils" can use "net u...

Hi All, Can somebody help me set this up. I'm trying to set up a public folder on my SAMBA server which will let my users create their own folders to store their files. And not let everyone delete them. Following are the problems I'm having: 1) If I set the directory rights to 755 on /exports and share the /exports/public directory with ~/public set to 755 Users can't create

Hi all, Just a quick question about login scripts for a large number of users who change rooms a lot. I have several rooms each with a printer, and nearly a thousand users divided into two main groups - pupils and teachers who change rooms on a routine basis. Is it possible to set up multiple login scripts that would be executed in sequence i.e. run by user is %u, and machine is %m is it possible to say run %u to set up shares followed by %m to set up the right printers for the room their in? Thank...

...ation into dbcheck (4.1.17) and some "human powered" valgrind like evalution using pudb, I came to the conclusion that it was the computation of the memberof attribute that was to blame. Disabling that attribute check in the dbcheck code did solve the issue. Actually there was a "pupils" group where all new pupils were automaticaly added (and which had in fact no real usage). So that was a group with about 10k members. Deleting the group resolved the dbcheck performance issue and the join at the same time. The dbcheck went for a few hours of run to just 6 minutes. I think...

...group both return full lists of users and groups from the UNIX/LDAP side suggesting that nss and pam and successfully communicating with smb5. The problems start when trying to access shares configured on the member server. If the ownership of the file is set to testuser who is a member of the pupils group, testuser can access it. If the owner is set to admin and the file is grouped to pupils, no-one in the pupils group can access it even with the group perms set to rwx. I suspect that as owner/users can access shares but groups can't that group mapping is stuffed. My questions are ther...

(yes, our nt4 usernames have whitespace in them, and yes, it's a headache - but that's another story) This is for a network of 600 pupils and teachers, who cannot remember if they logged in lowercase, uppercase or both. How can I either (i) enforce lowercase only, or (ii) have winbind treat "John" and "john" the same? Thanks -- Matt ___________________________________________________________ ALL-NEW Y...

...only = No I have also tried additional option: browseable = no (the home drive won't show up at all after login) valid users = %u (the folder can't be created from ADUC because the administrator doesn't have the right to do that) The server is running at school and there are several pupils who have the ability to misuse this situation.
