Hello! I'm collecting data on a refrigerator that I'm using to cure meat. Specifically I am collection humidity and temperature readings. The temperature readings look sinusoidal (due to the refrigerator turning on and off). I'd like to calculate the frequency and period of the wave so that I can determine if modifications I make to the equipment are increasing or decreasing

Hello, I have got a cluster sample using an election dataset where I already had the final results of a county-specific election. I am trying to figure out what would be the best sampling design for my data. The structure of the dataset is: 1) polling station (in general schools where people vote, for a county, for example, there are 15 polling stations) 2) inside each polling station, there

Hi all, I''ve been playing around with Arel this week (actually outside of Rails) and found an issue with the clone implementation. I''ve added a patch and a testcase here: https://github.com/codders/arel/commit/660f706491ac012cb133554cffeaa6b9ae6046e9 and made a pull request against the rails/arel repo. I''ve also been playing around with support for ordering on

Hey, We hit a bug today because Arel::Visitors::ToSql is not threadsafe. Here is what is happening: Arel::Visitors::ENGINE_VISITORS is a cache of visitors instances. These instances are not inherently threadsafe because it contains state ''@last_column'', ''@connection'' that is shared between threads. The other variables ''@pool'',

Hello, Arel::SelectManager (arel 2.0.9) uses following statement to insert a new record: @engine.connection.insert im.to_sql, ''AREL'', primary_key_name, primary_key_value But in DatabaseStatements insert ist defined as: insert(sql, name = nil, pk = nil, id_value = nil, sequence_name = nil) Actually, Arel::SelectManager does not use the sequence name. This leads to issues

Dear R-colleagues, I am quite a newbie to R fighting my stupidity to solve a probably quite simple problem of generating artificial data with defined features. I am conducting a study of inter-observer-agreement in child-bronchoscopy. One of the most important measures is Kappa according to Fleiss, which is very comfortable available in R through the irr-package. Unfortunately medical doctors

Cucumberists (and RSpec Classic users ;): How can we convert a Cucumber feature file into HTML with syntax highlighting? Not the test-runner output; that''s preprocessed so it does not match the input file... Tx! -- Phlip

im a begginer in RoR and am using rails 3.2.3 and ruby 1.8.7 This forum has helped me to progress but I''m confused by one thing. My app is supposed to allow seaching for results depending on the check boxes that are checked.

I''m a graduating student of IT right now and in a couple of months, we''ll be starting on a new project in the University.

I''ve got a table of events, and each event has a boolean attribute is_ten_event. On each row of the table is a chekbox to edit the value of is_ten_event, so that multiple rows can be edited with one submit. In order to allow boxes to be un-checked as well, the logic in the controller works like this get array of events from checkboxes that are ticked. make all events.is_ten_event =

I''m 99% certain that this is what''s being discussed in https://github.com/tenderlove/mechanize/issues/168 But I''m not sure what the remedy is. My production app is running on Heroku, so I need a fix that I can push there. Can someone post instructions that this neophyte can follow? (I gather I''m supposed to fork and add the current master version from

I have a form that allows me to search a hotel by city or name and by rating through radio buttons. It all works. However, my hotel model has_one :facility, this facility model is composed by several boolean fields (for example, roomservice:boolean restaurant:boolean and so on) The question is, I want to add checkbox fields for each facility I have and in the search form, when the user selects

I trying to create a select using Arel but I''m passing three parameters, I want to include the parameters only if they are different to nil or blank.

Pinging @tenderlove Some questions on how best to move forward with this: 1.) AC::Live is making use of the stream object on ActionDispatch::Response. Should the rack.hijack_io object be used instead of this in AC::Live or should ActionDispatch::Response be changed to use rack.hijack_io? 2.) What do you think about changing AC::Live to work with adapters? I suspect the primary use case for

Hello rubyonrails-core, I’ve been looking into possible changes to ActiveRecord / Arel to make it easier to write Rails applications that are free of SQL injection vulnerabilities, and in particular do so in a way that makes it easy for a code reviewer to verify that the app is safe from such bugs. The concern: ----------------- With the ActiveRecord API as is, it’s relatively easy to write
