Hi *, In an attempt to go back to the drawing board and learn RoR some more - I have built the depot application from the agile book. After finishing I tried to create a user for the admin section, however when ever I go to: http://localhost:3000/login/add_user It redirects to the login action, I don''t see the [add user] submit button?? I am sure this is connected to the

Hi ! I''m using daemontools[1] to manage a few processes on my Debian box. Among other things, I use it to manage svnserve, because it uses less memory than Apache. My /service/svnserve/run looks like this: #!/bin/sh su svn -c "/usr/local/bin/svnserve --foreground --daemon --root /var/svn" Is it safe for me to run like that ? If an attacker cracks svnserve, what will they

Hi, Can I use DTrace to determine memory status? 1.Total Physical Memory, Used Memory. 2.Total Swap Space and Used Swap Space. I did find few DTrace scripts but had too much in them and I am unable to chop off unwanted lines of code due to lack of knowledge. It will be very helpful if some one can share the piece of code that serves my purpose as mentioned above. Regards, Ramesh. Ramesh

Having fought my PXE config and eventually getting it to work (had to comment out the group { } statments ? I now come across another issue I cannot resolve and would appreciate some help. in my /tftpboot/pxelinux.cfg/default file I have cause to use the APPEND statement to pass options to the kernel being used. Unfortunately this line has now become longer than 255 characters and appears to be

Hi. I''m trying to monkey patch the rails_admin gem. First, I tried to add a file in config/initializers containing: RailsAdmin::MainController.class_eval do def get_sort_hash CODE HERE... end end It was only loaded once, and then the method from the gem was always executed instead of mine. I also tried to add the code in lib/ with the correct line in config/application.rb to load

I really would like to know how people are using the Story and Example runner to write their software.It would be great to get some direction on it, because I think I''m missing some points. Taking the outside-in approach in thought: At first we write a high-level customer-facing story, this story fails. Then we start using mocks at object level to use them as a design tool, and so we

Hello again! I''ve another "what would you do in this situation" question. You''ve got 6 controllers, one named base. The other 5 controllers extend base. Currently they share one layout. Your layout displays navigation. However, there are two actions inside base for which you do not want navigation displayed (index, new). Do you... a) Add logic to your layout telling

Hey, Rapid web development is all when and good but when it takes 4 months to rise anywhere in google it certainly takes off the shine. You hear of zero to hero.. crashed the server.. minted before toilet break.. I was wondering if any heros would share their marketing strategies.. or prehaps an amazon link to "Post-Agile Web development". Does anyone plug an app purely based on its

Hi, I am working thru the Ruby for rails book. On page 30 David Black talks about running erb from the command line i.e. $ erb erbdemo.rb just as you would a normal ruby prog ($ ruby erbdemo.rb) but when I try to do this I get command not found. How do I make this work? I am running Linux (Ubuntu Breezy) Regards, Paul

Hi *, I have been using radrails as an IDE for awhile now and we were getting along just fine - but recently it has just gone totally postal?!?? I created a new rails app - when I click to expand the folders there is no framework in place, just the root folder of the app. To add insult to injury two weeks of work also just disapeered - I kid you not just gone without any deletion on my part.

MainController implies main.rhtml, which will automatically have access to the methods inside MainHelper (in \app\helpers\main_helper.rb). Should not the partial templates called from main.rhtml via <%= render :partial => ''partial'' %> also have access to the methods in main_helper ? I have tried <% display_dates = create_display_dates(@events) %> and <%

Hi All I can''t for the life of me see what is wrong with this. Maybe it''s cause it''s midnight... I want to put some data in a session and I have some code like this: class ApplicationController < ActionController::Base model :mything def ApplicationController.chosen_thing session[:chosen_thing] ||= MyThing.defaultThing end end So whenever I try to

I am interested in studying the binary representation of numerics (doubles) in R, so am looking for possibilities of output of the internal binary representations. sprintf() with format "a" or "A" is halfway there: sprintf("%A",pi) # [1] "0X1.921FB54442D18P+1" but it is in hex. The following illustrate the sort of thing I want: 1.1001 0010 0001 1111

Hi, I have a samba 3.0 current CVS from 01/08 running with ldap as the backend. It been working fine for the past few week until late last week. I can join a machine to the domain and I get an entry in ldap one in ou=computers and one in ou=users (as normal). Everything looks fine until you try to login to the win2k box. When you hit enter after typing in username + passwd you get an error

Hi, I have a legacy web site based on ruby on rails 3.0.9 which works just fine with Firefox, chrome and IE 8, but I receive an HTTP 406 error every time when I check the web site with Internet Explorer 9. I narrowed down the problem to the respond_to + format.js + render :update trio, but I did not manage to solve the problem until now. I created a small example for reproduction: The action

I'd like to get a measure of goodness of fit for a heirarchical clustering result from hclust. Something that would indicate the extent to which the dendrogram accurately represents the original dissimilarity matrix. Is there an easy way to do this? Or, does anyone have code for computing distances between nodes given an hclust structure? So far, my searches have come up dry. -- David

Hi, I just installed ROracle and RDBI. The connection to the database seems to work also. My problem is when I am selection rows that really exist in the database, it is returning nothing. Where should I look to see what could be my problem? Thank you very much, Mathieu > drv <- dbDriver("Oracle") > summary(drv, verbose=TRUE) <OraDriver:(6721)> Driver name:

Take the following example: a <- rnorm(100) b <- trunc(3*runif(100)) g <- factor(trunc(4*runif(100)),labels=c('A','B','C','D')) y <- rnorm(100) + a + (b+1) * (unclass(g)+2) m <- lm(y~a+b*g) summary(m) Here b is discrete but not treated as a factor. I am interested in computing the effect of b within groups defined by the
