undefined method `'' for #<DRb::DRbUnknown:0x2501bd4>
I tried installing BackgrounDRb today. Followed the readme, made a
little worker for myself and executed it within the code. But I keep
getting this error. I must''ve gone over the README a zillion times.
Any idea what it is?

Testing worker classes
Hi,
Does it make sense to test a worker class by calling
Middleman.new_worker? Or should I just be testing the functionality in
the do_work method, with, say, a mock object. This seems like a really
ugly DRY violation: you''d need to keep the code in the mock and the
real worker in sync.
That''s the philosophical half of my question. In fact, until someone
tells me why I

Problems with ActiveRecord in workers
Hi *,
are there some special settings except of "load_rails: true" to make
ActiveRecord models accessible within my workers?
I''ve just installed the latest version of this great plugin, but I keep
getting
undefined method [] for #<DRb::DRbUnknown:0x12345> (line 105 in
backgroundrb.rb)
when one of the arguments for the worker is an ActiveRecord object.

''m having trouble with BackgrounDrb
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

strange issue with backgroundrb behind apache/lighttpd
I''m getting strange data back from my worker whenever I run our rails
app with more than one dispatcher under lighttpd.

user submits data to rails app. rails app hands off data to worker,
which goes and does it''s thing, storing results in an array of
response objects (the array is an attribute of the worker). the

how to present a table in powerpoint?
Hi,
I have a nicely printed table of results generated by R's
> print(myresult)
where myresult is a "data frame".
I am trying to put this table into a powerpoint slide for presentation without re-typing and re-formating, i.e.,
present it as it is in the R window. This saves time when there are a lot of tables to be presented.
I tried

Dots argument in apply method
Hello everyone,
I'm working on a package using S4 classes and methods and I ran into the
following "problem" when I tried to create an "apply" method for objects
of one of my new classes. I've found a way around the problem but I
wonder if I did not paint myself into the corner. I'd like your opinion
about that.

How to get 'R' to talk BACK to other languages / scripts??
Hey everyone,
I know that I can call 'R' from other scripts, and that I can make
command calls from 'R' (e.g., using system() ). But how can I get 'R' to
RETURN values to the script that called it. E.g., I would like to be able
to do something like the following (as a simpler example) from a bash
script:

objects and environments
Dear list,
I have two functions created in the same environment, fun1 and fun2.
fun2 is called by fun1, but fun2 should use an object which is created in fun1
fun1 <- function(x) {
ifelse(somecondition, bb <- "o", bb <- "*")
## mymatrix is created, then
myresult <- apply(mymatrix, 1, fun2)
}

BackgrounDRb background task runner and Application Wide Context Store
Friends-
I''m happy to annouce the first alpa release of BackgrounDRb. This is
a small framework for managing long running background tasks that
allows for ajax progress bars and more. It also serves as an
Application wide cache and context store for when you need something
like sessions but shared between users and multiple backend processes
like fcgi''s or mongrels.

I am getting my hands on trying the cool BackgrounDrb plugin.
Following various discussions and suggestsion, I included "include DRbUndumped"

after I tried this and hit the page that uses this model. Does anyone
know why this is so? Is it possible that an object cannot be

Question about acls
Hi,
I''m not much of a developer but I''ve been using backgroundrb for a
while now and with the release of 0.2.1 it looks like I can finally
upgrade from the old version (0.2.0 had some weird issues when jobs
just wouldn''t run, seems to have cleared up now - Thanks!).
Anyhow, while I''m doing this, I would like to tackle this problem.

Versioning the contents of a table as a set
I am looking at using acts_as_versioned to manage revisions of data in
several tables in my application. However, the default behavior of
acts_as_versioned appears to apply to individual rows within a table. The
tables I want to version are complicated lookup tables and what I really
want is to version the entire contents of each table as a single set.

Instantiating middleman and worker from inside a model?
In short: how (if possible) would i go about arranging it so that i
can instantiate a middleman and set a worker going from within a
method in one of my models? or is this a weird thing to be wanting to
do? (
My specific situation: I have an ''Image'' model in my application. An
actual image file associated with the model is being stored on
amazons s3 system.
