I''m misunderstanding how stubs works
We''re still just starting out with Mocha/Stubba, so please forgive any
newbie errors.
I''m using "stubs" to test some realtime functions, to control exactly which
time is returned from Time.now. I would expect the following test to pass:
def test_two_stubs
t = Time.now - 60
Time.stubs(:now).returns(t)
start_time = Time.now
t += 20

Need advice - which version to use?
Greetings!

slightly OT - Ruby division
Hey all,
In my code, it seems that when I divide two integers, the result is an
integer. Is there any way to make it such that when I divide two integers,
the result is a double?
Any help appreciated,

[LLVMdev] interesting LLVM code optimization issue regarding timer registers
This problem was reported to me by a friend who has an LLVM port that is
not put back to open source.
Essentially, there is an intrinsic call _lr which is a load register.
so then user code has something like:
start_time = _lr(TIMER_REGISTER)
.....
some_code_to_time
....
end_time = _lr(TIMER_REGISTER)
So what happens is that LLVM moves the code as follows:
start_time = _lr(TIMER_REGISTER)

Hi Xiph.org Team.
We are using opusfile library <https://github.com/xiph/opusfile> for

Mini_Magick Problem
I can''t for the life of me figure this out. Been banging my head on
this since the weekend, and can''t see what I''m doing wrong.
This code works:
image.resize("640x480")
image.write(path)
I run this and I get the resized file just fine.
This doesnt work at all:
width = 200
height = 100
dimensions = "#{width}x#{height}"

find_by_sql column types
Hello--
There must be a better way to do this. I have a class method in my model
that finds averages and does a few calculations using find_by_sql. The
problem I¹m encountering is that all computed columns from MySQL come back
as type string. E.g.,
def self.find_averages(domain_id)
if @@domain_average
return @@domain_average
else

backgrounDRb problems with results and MiddleMan
Hi there,
I''ve been experimenting with implementing BackgroundDRb in my rails app but
am running into some problems.
The primary problem I''m getting is in cleaning up worker threads, or getting
any kind of response out of worker threads.
If try using the response function/hash in my Worker the worker will not
execute reporting that response is an unknown variable or function.

Double and single quote usage in AWDWR
Hello everyone!
I''ve noticed, that the book uses double quotes almost everywhere. It is like
<%= javascript_include_tag "prototype" %>
I''ve checked the "programming ruby, 2ed" book and found that double
quotes are most suited when escape sequences and substitutions are
required. Isn''t it more semantically correct to write this code like

compounding precipitation based on whether falls within a day
Using the small reproducible example below, I'm wondering how best to
complete the following task:
In the small reproducible example below, the 3D array prec has indexes that
correspond to time, x, y (i.e., prec[time, x, y]). In this case, the time
index is hours since some predefined start time. I'd like to add up all
the time indexes in 'prec' based on whether or not the

Can Win32 service more than one rails request at a time?
Hi,
I am trying to run Mongrel on win32 to serve an internal rails application.
We are accessing legacy data, and some transactions can take 5 to 10 seconds. This is holding up every other request. The -n does not seem to be supported on Win32.
Am I missing something, or should I look elsewhere to serve my Rails app on win32?
Thanks,
Walt

how do I validate currency format if I am storing in cents?
Hi all -
To avoid floating point issues, I''ve decided to store monetary values in
cents in the database. However, the user will enter these in dollars
and cents. Two questions:
1) How do I do the validation for the currency format? It looks like
ActiveRecord truncates the cents since it thinks the field type is a
Fixnum. Am I forced to do validation in the controller?
2) Where
