Hi guys, I am trying to extract the class name of a parameter to a method call in objective-C. The code I am parsing is: - (void)testAddConcreteDataModel:(DFDemoDataModelOne*)helpmeh { [self.dataModels addObject:helpmeh]; } And the result I need is the type of class of helpmeh, which is "DFDemoDataModelOne". So far I have the following code, which outputs: "[(DFDataModelContainer).dataModels addObject:helpmeh]" if (cursor.kind == CXCursor_ObjCMessageExpr) { _...

Hi I''m struggling to find a neat way to spec this. The Sequel ORM doesn''t support automatically destroying dependent models. It''s easy enough to do in a callback though: class Changeset < Sequel::Model has_many :migrations, :class => DataModel::Migration before_destroy do migrations.each { |m| m.destroy } end # ... end

Hello, I am trying to estimate 4 parameters of a non-linear model using nls. My model function is a Fourier integral and is very expensive to calculate. I get the following error: > theta0 <- c(0.045, 1.02*10^(-4), 0.00169, 5.67*10^(-4)) > res <- nls(log(y) ~ log(model(theta,r,t)), data=dataModel, + start=list(theta=theta0), trace=TRUE, + control=nls.control(tol=1e-2))

Hi All I have downloaded the opensource xapi source code. I am not sure what the functins of the follow modules: 1 block_device_io 2 datamodel 3 xiu (I am puzzled by the name "xiu") 4 stats 5 rpc-light 6 rss 7 xb (I think the xapi needs not to talk to xenbus directly) 8 xsrpc (why it writes some "rpc" keys to path of "domain/<domid>" in the

Hi All, I''ve been trying to figure out what''s wrong here for a little over a day and figured i''d reach out to the ROR list. A pastie explains the code a bit better than directly in email: http://pastie.org/private/mvu0zr1xm18bsk6nfbyama Basically i have an Artist, and he has many Songs through a join model called Releases. An artist can be "featured" on a

Data frames are lists of columns. The names() function is appropriate for lists. It doesn't pay to fall into the trap of thinking that data frames are truly symmetric between columns and rows, because there is a performance penalty for accessing rows that is greater than the cost of accessing columns. With that in mind, thinking of data frames as lists is preferred, so names is preferred

hey, i''ve created a basic content management system using rails and scriptaculous. I posted a first version last week, but I heavily extended it since then. Features: Pages are arranged in a sortable tree (sortable by drag and drop) Pages have "nice" URLS (no /index?articleid=97361496 or something) Cacheing on page basis every page has a layout with a number of columns page

The help text for row+colnames {base} states: "For a data frame, rownames and colnames eventually call row.names and names respectively, but the latter are preferred." Why are they "preferred"? Why is it names(), not col.names()? I have only ever used names() for vectors - I'm surprised it works on data.frames... IMO this is not great for code readability, thus

Hi all, After working on my first rails app and having handed over some very sophisticated coding from a lot of you guys. My app does what I want it to do, but I''m no where near the end yet, and it seems that the KISS and DRY objectives already went down the drain. It could be lack of knowledge, only doing Ruby on (and) Rails for a month, but I''m stuck on the following:

In an migration file there is one up and one down method. Below is from Agile Web Development with Rails: class CreateOrderHistories < ActiveRecord::Migration def self.up create_table :order_histories do |t| t.column :order_id, :integer, :null => false t.column :created_at, :timestamp t.column :notes, :text end end def self.down drop_table :order_histories end end Why is there a drop

Hi guys, Does anyone know if mongrel has a built-in timeout for requests that take too long? If so, how do you increase it? I''ve found that some server requests are timing out. Complicated requests are already being farmed out to asynchronous processes. But some of the more basic requests are timing out when we have our peak server load in the mornings (the bottleneck is the

You can walk around, and everything just

Hi, We've got a fairly simple samba setup (no ldap/winbind etc) and until recently everything worked fine (using samba-2.2.5). But after switching to samba-2.2.6 w2k-clients fail to run the netlogon-scripts. When i look at the client it says: logonserver=\\<workstationname> BTW. The output of "nmblookup -S CPB" (to me) seems to say that CPB is the logonserver. querying CPB
