Hello all, I would like to read the specific line number row of a direct access file (which is stored as a n_row*n_col matrix of elements kind=p) without reading all the preceding lines (i.e 1,2,..,row-1). Is there a function in R that can perform this task? To solve my issue, I tried without to call Fortran from R by doing the following steps: I) I wrote a subroutine in fortran called

Hello! Sometime ago I ran across a webpage where someone had identified the full callback sequence for an object lifecycle including AASM with it''s :enter and :exit and whatnot callbacks. Unfortunately, I can''t find it and searches don''t seem to help. Does anyone have a reference to a page that shows the callback sequence with Acts As State Machine (the gem)? I think

Hi all, I''m trying to link to the "Next Entry >>" from the current entry page (in show.html.erb).

I''m sending plain text and html emails by having multiple files for each email I send. For example, for my registration email I have a registration.text.plain.erb file and a registration.text.html.erb file. I want to use a layout for the html version of my emails. In my mailer I put: class AccountsMailer < ActionMailer::Base layout ''email'' ... end

So I''m happy to see that ActionMailer supports layouts now (it may have for a while, but I just now realized it). But I don''t see a way to turn them off selectively or by multipart type. For example, if I have a layout that''s really simple in "layouts/ email.html.erb": <div style="border:1px solid gray"> <%= yield %> </div> I

Acts_as_soft_deletable is a rails plugin that provides the ability to soft delete or disable models. When models are destroyed, they will be archived so that they can later be restored easily. Its similar to acts_as_paranoid but uses a different approach that should make it a little more foolproof. See the README at the following url for a better description. github url:

Hi, I''m announcing Hirb, a mini view framework which enables script/ console to provide custom views. Out of the box your activerecord objects come back as ascii tables. You can also configure your tree-based models to return as ascii trees: Numeric |-- Float |-- Integer | |-- Bignum | `-- Fixnum |-- Date::Infinity `-- Rational I''ve written two tutorials on

Hi all: For example I have: class Color < ActiveRecord::Base belongs_to :ball end class Ball < ActiveRecord::Base has_many :colors end What I want to do is to write a method that: 1. takes the result of Ball#colors, which is an array of Color objects 2. do something with the array 3. return the result but I want to name my method Ball#colors, i.e. I want to overload the generated

Considering an object with several has_many :through => associations, what is the ''best'' way to handle validations? As an example: class Student < ActiveRecord::Base # some attrbutes like # :name # :grade # relationships has_many :students_assignment, :dependent => :destroy has_many :assignments, :through => :students_assignment has_many

I have a situation in which I want to validate a number is not zero. Both positive and negative values are acceptable, just not zero. validates_numericality_of has an :equal_to attribute, but I don''t see a :not_equal_to. I have not yet been able to find anyone who has discussed this. I did find information about custom validators, so I am now using a custom validator to check the field

There''s got to be an easier way... I am building an event manager and as part of it, the user selects the time zone of the event from a drop-down list using the time_zone_select helper. This is stored in the events table as a string. Because of legacy data which is stored in UTC, I want to keep the dates and times in the table as UTC but when I display it, I want to show the abbreviated

I am currently using a copy of Asterisk checked out as the code of 10 days ago from Asterisk and the: sip show inuse reports that I have 3 incoming connections to one of the Grandstream phones, even though that isn't the case.

Hello all! I have a conundrum that I''m _sure_ someone else has already thought of and solved. How does one best handle the scenario of association object changes and data integrity? For example, if I have a standard ecommerce site that sells Products and people can have Orders and an Order has_many Products... then, what happens if Product #3 is part of Order #2 but at some point, the

We''re developing a system that''s used for tracking company IPO data and we''re running into a few number storage issues. For large numbers, i.e. numbers greater than 100 million, MySQL insists on storing these as scientific notation. I don''t really have a problem with that but when we want to edit these fields using something like: <% form_for(@company) do

I am new to asterisk and have been playing with it for just a few days. The GrandStream BudgeTone-102 equipment I have allows me to do a blind transfer, but I am interested to know how to do something which isn't blind. I have managed to enable the call parking which allows me to send a call to extension 700 for somebody to collect, but it still seems rather awkward. I also have

Does anybody know how to do an international call using NuFone. I realise this isn't really the place to ask, but NuFone appears to be closed for the weekend and would like to have a try at this before tomorrow. I assumed it would be '011' for an international line followed by country code but that doesn't seem to work. I am getting: -- Executing

When you look at 'show translation' you see: Translation times between formats (in milliseconds) but is this the number of milliseconds required to convert 1 packet of data, or the amount of time required to translate 1 second of data? I am assuming it is the time for 1 second. Thanks, Michael -- Michael T Farnworth Maxima Systems Ltd (http://www.maximasystems.com) 16 Woodbourne Sq

I had a working configuration whereby an incoming call on an ISDN line would be sent out on the second ISDN line, but since I updated to the latest version of Asterisk I get this error message: WARNING[311315]: File res_parking.c, Line 226 (ast_bridge_call): Bridge failed on channels CAPI[contr1/s]/0 and CAPI[contr1/01624619052]/1 The message comes up as soon as the outgoing call is answered
