similar to: problem with worker status

Hi. I am using BackgrounDRb to process thumbnails and upload to S3 - things are hunky-dory in development (thumbs are generated, these are uploaded to S3, the metadata is saved to trhe DB, and I get a nice status page updated by periodic calls via ask_status), but when I tried to deploy to our staging server and stop/start BackgrounDRb via Capistrano, things blew up - well, not exactly,

Hi there, I''ve been digging around trying to find some information (mostly examples) on how one would handle a progress bar upload using BackgrounDRb and File Column. I did read http://backgroundrb.rubyforge.org/ and Ezra''s blog of course, but I still have a few questions. I made a simple upload form (as a test) that is submitted to the "upload_song" action. def

Hi, Could anyone please help me understand why Clang reallocates the same memory address for different variables while their lifetime intersect? Here is an example code: #include <stdlib.h> #include <stdio.h> #include <memory.h> #include <alloca.h> /* Checking information */ static int solutions[] = { 1, 0, 0, 2, 10, /* 5 */

Hi all, Probably a simple question, but I just can't find a simple answear in the older threads or anywhere else. I've added some new vectors as columns in a data frame using cbind(). As they're all put as the last columns inte the data frame, I would like to move them to specific positions. How do you do to change the position of a column in a data frame? I know I can use

Data has the first row for variable name and the first column for sample name. I want to take "Log" for all data, but how to compute without the first column for sample name. That is, column 1: sample ID column 2-10: data I want to find an average on each column (2-10) > apply(raw_data,2,mean) Error in Math.data.frame(list(sample_id = c(1L, 2L, 3L, 4L, 5L, 6L, 7L, :

I have hundreds of humans who have undergone SNP genotyping at hundreds of loci. Some have even undergone the procedure twice or thrice (kind of an internal control). So obviously I need to find those replications, and confirm that the results are the same. If there is discordance then I need to address it. I tried to use the aggregate function nr.attempts

hi guys..please help me with this i am working on two data frames one goes like this: DF1 Sample_id RepairHours Denatured Dose ZeroMean FourtyFiveMean NinetyMean 1 SDM071 0 1 B 60.5 19.0 45.0 2 SDM071 1 1 B 46.0 23.0 42.5 3 SDM071 2 1 B 52.5 24.0 40.0 4 SDM071

Finally found a nice date chooser script (http://projects.exactlyoneturtle.com/date_picker), but am a little confused how to implement it. So I put this where I need the date picker: <a id="_name_link" href="#" onclick="DatePicker.toggleDatePicker(''name'')" class="demo_link">[ choose date ]</a> <div

I''ve been hacking on this for awhile and am not even getting close. Consider the following... results = Sample.find(:all) total_counter = results.each{|result| #Add together result.counter} I just want to simply iterate through the list and sum the counter field for each row into an aggregation. I could do it in a full for loop, but is there a nice one liner I''m missing?

I''m developing a stateful Ruby application that needs to keep data in one location where all people accessing the site can modify its contents. This data will be read-from/written to often, so I would prefer for rails to keep it in memory, rather than a database. My frist try involved global variables. After discovering that they were being "re-initialized" with each new

Howdy Folks- I''m happy to announce a new release of BackgrounDRb! I have added quite a few new features and included some nice patches from folks on the list. $ script/plugin install svn://rubyforge.org//var/svn/backgroundrb All of the code now stays within the plugin and the start and stop scripts are now just stubs. This makes it easier to tweak or figure out how it works.

I''ve been using backgroundrb since back in March 2007 or so. It''s been working mostly OK for me, but since the old version doesn''t seem to work out of the box with rails 2.0 for me, I decided to test out the latest version. So, I''m looking at the scheduling, and trying to figure out the best option for what I want to do. What I have is a set of workers that

I''m retrieving a list of tasks to display in a page using @delegatedtask_pages, @delegatedtasks = paginate :tasks, :conditions => "user_id = " + session[:user_id].to_s + " percent_complete <> 100", :order_by => ''due_on asc'' I''d like to only list the tasks which have been assigned to other people. I have a table called

Ezra, Suppose a chatroom application, a RailsApp + 2 backgroundrbs: MiddleMan1& MiddleMan2, running in 2 machines. When Chater1 login, RailsApp call MiddleMan1 to get something about Chater1 from db to memory, like his contacts or other personal settings. When Chater2 login, RailsApp call MiddleMan2 do the same thing. But who is reponsible for the Global Data? like a Online Chaters

i''m in a team that is currently developing a web 2.0 application that really needs to scale in the very near future. we are using backgroundrb for some of the server tasks. currently, we have two servers (in RubyOnRails) that connects to a single backgroundrb daemon. is there a way that we can run multiple backgroundrb and have the servers do a round robin on them to retrieve a worker

Hi, I''m having a problem where connections started through BackgrounDRb::MiddleManDRbObject.init are not stopped, resulting in an ever growing established connections between my Mongrels and remote backgroundrbs I added DRb.stop_service to my code executed after requests that init MiddleManDRbObjects but that does not help. Any ideas? Thanks, Robert Bjarnason

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I was testing oz/imagefactory on 32 bit arm, you have to have kernel-lpae installed to run kvm. while you can have the regular kernel installed also. You end up having the system booting the regular kernel and you do not get kvm. Ideally supermin will work with the lpae kernel.

So I''ve worked through Agile Web Development with Rails and I''m now trying my first little app to get into the swing of things. Its a task tracking app where people can create tasks and assign them to others, and also log time against the tasks. I''m having trouble working out the model relationships. This is what I''ve got so far, but its not right as
