I''m developing a system similar to the ForumExample (http:// wiki.rubyonrails.org/rails/pages/ForumExample), and stumbled upon the following. Let''s say I wanted to get all the categories a certain user posted in. How do I get that information withouth using a custom query through :finder_sql (and thus losing the find_in_collection ownage)? It would also be great to see how many

Hello, I am hoping someone can help me with the following multivariate issue: I have a model consisting of about 50 covariates. I would like to reduce this to about 5 covariate for the reduced model by combining cofactors that are strongly correlated. Is there a package or function that would help me with this in R? I appreciate any suggestions. Thanks, Ian

Hi All, I use dovecot (v2.3.4) with a SQL backend for user authentication, passwords are stored in CRAMMD5 format. My SMTP server uses "doveadm auth" via auth-socket to perform sender authentification. To shut down SMTP access for hacked passwords I want to have a dedicated flag in the user database to allow/disallow SMTP for a user withouth disabling his account for IMAP. So, is

Hi there! I been using samba3 with ldap for years, and now im about to move to samba4 to leave the slapd. I didnt try yet to migrate the directory from samba3 to samba4. But i did setup a new domain and everything looks ok. My doubt is related to the configuration of the computers with linux so that they can take advantage of the users and passwords of ldap. But also, groups that are unix

We have a couple of NT4 boxes I'd like to replace with a single samba box. One is a PDC (no BDC) that now does nothing but handle authentication for the other box which is just an NT4 member server with a big hard drive and a whole bunch of shares. There are also a few printers that are littered around the place connected to various Windows (2000 and XP) client machines and shared across the

Hi, I have a windows 7 machine withouth local administrator account. I need to create such an account. I can log in to the machine with a user on my samba domain. What do I need to do in order to get administrator access, or access to create an local administrator account? I have tried to do this: [root at float samba]# net rpc group addmem "Administrators" 'DOMAIN\username'

Dear R gurus. Is there an R function equivalent to octaves / (Right division) withouth forming the inverse of Y' using solve ? [snip - from octave docu] Right division. This is conceptually equivalent to the expression (inverse (y') * x')' but it is computed without forming the inverse of Y'. If the system is not square, or if the coefficient matrix

Hallo all, we are completly new to this list and also to wine, so sorry if the question is too simple. We are trying to install and work with wine, withouth results: err:win32:PELoadLibraryEXA can't load C:\WINNT\system32/comdlg32.dll although the file comdlg32.dll exists in the directory. This is one of three messages I cannot copy from the terminal Question: our Windows partition is

I have Asterisk 1.0.5-BRIstuffed-0.2.0-RC5 up and running. Everything seems to be running fine but after some time asterisk just goes crazy (even withouth any incoming or outgoing call activity perviously). If I leave the box up for some time * goes haywire and the console is flooded with this message: Ouch ... error while writing audio data: : Broken pipe At that time I can see that there

Hi Jakob, > New_MI_1:: Vreg1 = 0 ; Vreg1 and Vreg2 > are 32 bit virt. regs. > New_MI_2:: Vreg2 = COPY C:lo_sub_reg. > New_MI_3:: B= REG_SEQUENCE<Vreg1, hi_sub_reg, Vreg2, lo_sub_reg> ; B > is a > 64 bit virt reg. I used this approach and it worked find until I hit, what I believe is, a bug in the register coalescer. When the register

I'm curious if there are users of RPy on this list. I've recently created a gui front end using Tkinter for some python scripts I've written for some of our internal operations and I am quite pleased with how this program works. I wonder if it is possible to also get this gui to run R functions through the use of RPy. Going even a step further, I wonder if it is possible to get this

Thanks Duncan for the replyI can not suppress anything these are radiation pattern measurements that are typically are taken at X,Y and Z planes.

Hi all - I've been working on a lite ORM and database abstraction package for R. Formatting complex queries by hand has always been an error-prone hassle, so I've tried to do away with that as much as possible, instead, using R objects to represent elements of a database system (statements, clauses, operators, functions, fields, tables, etc.). R5 classes have made the development of this

Hello, I''m developing an app that basically, receives a 10MB or less XLSX files with +30000 rows or so, and another XLSX file with about 200rows, I have to read one row of the smallest file, look it up on the largest file and write data from both files to a new one. I just did a test reading a few rows from the largest file using ROO (Spreadsheet doesn''t support XSLX and

Hi, I'm processing a data file with the following structure: #index time distance 1 10 500 1 15 300 1 23 215 1 34 200 2 5 400 2 13 340 2 15 210 3 10 200 3 12 150 3 16 30 etc My intention was to generate line plots for the datapoints using their index to group the elements. I managed to get something to work using a for loop and some conditionals but I was wondering if
