Hi, for those of you who haven''t read: http://meyerweb.com/eric/thoughts/2006/05/08/flummoxed-by-frameworks/ ""Oh", they gush, "you should absolutely try Ruby on Rails! It''s so easy! It''s almost like writing regular English!" Which means they''re clearly on crack, because Ruby on Rails is so very different from a human-written language

Hello, I want to fit a Gompertz model for tree diameter growth that depends on a 4 levels edaphic factor (?Drain?) and I don?t manage to introduce the factor variable in the formula.

Hi, people! This is my first babble on this list, please be kind! :-) Last Tuesday, I wrote to the (likely) Webmaster of the R site to report a little problem, but also to ask for advice about how to get a bulk copy of the mailing list archives, from 2002 to now. While I quite understand that from Tuesday to now, there has been little time, and it is only normal that I did not receive a reply

What is the rails idiom for submit buttons on forms? All other field types have helpers, but button_to creates its own form, so should not be used. I''ve looked in "Agile Web Dev. with Rails" but can''t see what I should do instead. Is this "difficult" because it runs counter to AJAX type forms? And, related, is there a way to ensure that hitting return in

Hi, I''ve got a public\images\DownArrow.jpg and app\views\expenses\new.html.erb that want to present this image in the following context: <p> <%= f.label :vendor %><br /> <%= f.text_field :vendor %> <%= f.image "DownArrow.jpg" %> <br> <%= select_tag "test", options_for_select(@current_vendors.collect {

Agile Web Development with Rails doesn''t seem to have NULL in the index [or my eyes have failed me again], and web searching turns up lots of SQL statements containing NOT NULL. I have a table of loans, and I want to record when something was loaned and returned. The loan date can''t be null, or there''d be no entry in the table. The return date must be something

Hello, I have recently downloaded Sorcerer GNU Linux (http://sorcerer.wox.org/) which uses ISOLINUX for booting the installation CD-ROM. Problem is, I can not get the CD-ROM to boot. I have tested it on another computer, and it works fine (The CD-ROM has been written correctly). When I boot it on my home system, it gives me this error message: ISOLINUX 1.66 2002-01-01 isolinux: Disk error 00,

I read the 13th recipe in the book "Rails Recipes" from Chad Fowler. I install with gem the gruff-library (gem install gruff). After the installation, I download the "rmagick-win32-1.13.0_IM-6.2.9-3.zip" file and install it on my win32-machine. It was successfully! So, I create a controller with script/generate. In a method, which I wrote after the creation, I''ll make

Hi, I just got a comment from one of my IBM support engineeres that there is a problem with auth-passwd.c only calling authenticate() once. He claims it should potentially be called several times, in case several authetication methods are defined in /etc/security/user. F.ex.: SYSTEM = "NIS and DCE" Suggested (untested) patch should look like: ----------------- cut

I''m attempting to use the example given in the Rails Recipes book chapter 2, to create a select drop-down using the InPlaceEditor function (modified to be InPlaceSelectEditor. The example given works (a country list drop-down), but I''m attempting to use it to display a list of items generated from an object in another table that is linked to the table that I''m editing.

I create my rails app, with modifications to the default from a script. Having had to upgrade rails once, and knowing that this is likely to happen again because of the rapid updating of rails, it seems the most sensible way to do it. As a result, I often do /bin/rm -rf csestore and then run my script from another window to repopulate it. So naturally, to save having to cd into csestore, and

Hey all, Here''s where I post my mightly plea for a developer; also where I gush the wonders of these two educational, open-community youth projects. --- They''re both the product of some wonderful minds and have attracted the attention of interesting and unique organizations. A RoR developer would gain stardom as well, the lead web developer involved. Maybe not the same

The wine concept--a compatibility layer that allows running executables compiled for Windows on a Linux or Unix host--is a very useful concept that could reasonably be used to adapt between other platforms. It's somewhere between running a virtual machine and cross-compiling the application. Is there anything similar for other (non-Windows) guest platforms? Right now, I'm specifically

I would like to teach some scientific/statistical computing to my 13 year old nephew and was considering using R for this. He has a Mac G3 OS 9.1. I am looking for ideas for problems that would be interesting and motivating for someone that age. I recently taught him the basics of HTML and noticed that he particularly was intrigued by the ability to change colors; thus, perhaps problems

Hi all, I was wondering if anyone could point me to a good (ideally simple) example of RoR design. I am rather new to this subject, and I am playing with https://rubyforge.org/projects/mystic/ as an simple example to understand how stuff works, but I am not entirely convinced that it has been properly written in terms of locating html code, javascript code, etc. (e.g. There is a fragment of html

We are looking at implementing a Linux box running samba in the near future with about 1TB of disk online. The purpose of this box will be for basic file and printer sharing needs. I am doing research on the different journaling file systems avaible in RH 7.3 and up (ext3, reiserFS, and JFS) and was wondering if anyone has had any real world experience with them (mostly reiserFS and JFS) and

I'm trying (for a while now) to upgrade to 3.3.x my samba PDC, but I've troubles with the trusting PDC. While using samba > 3.2.4 on the trusted side, the trusting side can no more enumerate users and groups from the trusted PDC. Winbind raises the error NETWORK_ACCESS_DENIED while trying to connect with NTLMMSP. I saw this behaviour with 3.2.6, 3.3.0 and now 3.3.2 on the trusted

For reasons which escape me, my VMWare Server, which was working perfectly a week ago when I shut down my machine for vacation, no loner comes up with the formerly working Windows XP system - it just stays in the small window where it normally boots and does nothing. The vmware serverd log shows nothing particularly interesting, and I have reconfigured the vmware twice to try and fix this (which
