similar to: dynamic languages - how to leverage/make best use?

I have a new version of Rake that I''m (almost) ready to release. But before I make an official release, I would like some Rails folk to give it it try ... Why? Because it contains a workaround for the notorious Ruby 1.8.2 test/unit bug. Using this version of rails, it should be possible to unit test a rails app without patching the Ruby 1.8.2 test/unit library. Where to get it?

I''m using Hieraki to do some documentation for RubyGems. So far I''m lovin'' it. But I have a question. I currently have three books on the site. It seems that the chapter numbers continue from one book to the next. For example, the first book has 7 chapters (numbered 1-7). The second book has three chapters, but they are numbered (8-10) rather than the (1-3) I

I''ve been doing lots of research about different languages and frameworks for a project I''m planning. Your help in deciding what to do would be of great assistance. I used to program in highschool for a couple years. I haven''t done much since then and I know i''m pretty useless as a programmer. I know that if i put my head to it, I could muddle my way

hello Friends, I am a newbie to "Ruby or Ruby on Rails". A J2EE application architect at my day job. A fairly experienced PHP web-developer as well. After reading into the many articles on Ruby/ROR, have to admit looks pretty good so far. Really serious about getting into this and possibly developing some good Web 2.0 applications. Just wondering the best way to learn Ruby on

I have some code working that lists only items from a particular user. The code in my list action finds the user and then conditionally lists only his/her items: def list user = User.find(session[:user]) user_id = user.id @product_pages, @products = paginate :products, :per_page => 10, :conditions =>[''user_id = ?'', user.id]

Hello, I want to specify a linear regression model in which the metric outcome is predicted by two factors and their interaction. glm() computes effects for each factor level and the levels of the interaction. In the case of singularities glm() displays "NA" for the corresponding coefficients. However, svyglm() aborts with an error message. Is there a possibility that svyglm()

Sanjoy, in your blog post https://www.playingwithpointers.com/problem-with-undef.html <https://www.playingwithpointers.com/problem-with-undef.html> you describe a problem with LLVM “undef”, yet in your paper http://www.cs.utah.edu/~regehr/papers/undef-pldi17.pdf <http://www.cs.utah.edu/~regehr/papers/undef-pldi17.pdf> you do not suggest fixing this problem, even though in

Hello, R users, I have two factors (treat, section) anova design experiment where there are 3 replicates. The objective of the experiment is to test if there is significant difference of yield between top (section 9 to 11) and bottom (section 9 to 11) of the fruit tree under treatment. I found that there are interaction between two factors. I wonder if I can contrast means from levels of

I''m using Jim Weirich''s Builder library. The code I want to spec is xml.video do xml.id @video_id xml.views @views xml.date(@date.to_s) if @date end I''d like to mock it, rather than asserting that the XML is the right string. I can do one spec: specify "should create a video tag" do @mock_builder.should_receive(:video)

Hello all, Would somebody be kind enough to show me how to do a KS test in R for a lognormal distribution with ESTIMATED parameters. The R function ks.test()says "the parameters specified must be prespecified and not estimated from the data" Is there a way to correct this when one uses estimated data?

The normalization of the numerator (Ch) has been done by 'N' where as I would like to do it by 'N-k'. Is there anyway in the present implementation of ACF to normalize it by 'N-k', where
