I just started working with Ruby. Anyways I can''t seem to figure out how to have this message disappear. I was reading a tutorial and based on it, when I type in http://localhost:3000/MyTest/ it should say whatever I have written down on my my_test_controller.rb file. I first ran: ruby script\generate controller MyTest then I edited the my_test_controller.rb file It currently says:

mytest<-function(x,f){ sum(x*f)/sum(f) } cat(mytest,file="c:/mytest.R") Error in cat(list(...), file, sep, fill, labels, append) : argument 1 (type 'closure') cannot be handled by 'cat' how can i write the mytest function into a file c:/mytest.R with cat function?

Hi all, i was using bdrb a while ago and it wasn''t stable enough in version 0.2.1 for doing the job - it loss jobs or did execute only the first one invoked and so on. Now i gave the new version a try and i found a bug at playing around. When i start a worker_method over the normal Unix scheduler bdrb will start as much as possible the worker_method after the :end-time is reached.

I''m playing around with the Practical Rails Projects code, and was attempting to make a change for graphing data differently using groupings. Basically the code went from: total_weight = @exercise.activities.collect {|e| e.repetitions * e.resistance} workout_dates = @exercise.activities.collect {|e| e.workout.date.to_s} To: total_weight =

I am using Prototype 1.6.0.2 on Firefox 3.0b4. The following does not work when I enter it in Firebug: $A([1,2,3,4]).each(function(n) {alert(n);}); The above is just an example.

When using the ARM cross compiler we've run into an issue with LTO and optimized libraries. Consider you have an optimized library opt.a, which contains a version of memcpy.

The linker looks through the bitcode (via
