I have been using browsercam.com for CSS testing, but it is rather expensive. Recently, I discovered others using funadable.org to purchase a yearly membership as a group. A year long membership at browsercam.com costs $480.00. This gives us 25 user accounts. I am proposing that 25 people throw in $19.20 for their 1/25th share of the membership cost. Once I have raised $479.40 I will

Does has_and_belongs_to_many know to delete an object when the last reference to it is removed? In my case I have Receiver <<->> Message (with a join table of course), but have noticed that when the last receiver removes a message from the association the message still exists. Before adding code to manage this situation I want to check to see if I am missing something? --

Other than doing a raw SQL update the only way to update join attributes is to remove an object and then push_with_attributes correct? -- Lon

Hello I am a new user of R . and I ve problem with R and netcdf . I succed installation , I could use all examples . But when I take my netcf it is different . I want to do statistic on this kind of file . 1) first calculate mean . my data is like that through ncdump -h test.nc netcdf test { dimensions: lat = 301 ; lon = 401 ; time = UNLIMITED ; // (80 currently)

I am having a devil of a time with some runner actions. I can not seem to call any instance methods on found records. Even when I strip is down to the basics: def self.deliver self.find(:all, :conditions => ["#{Message.table_name}.status = ?", ''pending''], :include => [:site, :template]).each {|m| logger.info m.is_recurring? # my method logger.info

Awhile ago, I posted some information about SMS Aggregators, this is just a follow-up, based on changes in the US market. As of January 31st, any commercial application, sending to US networks, is required to lease a CSC (short code) from CTIA. A CSC runs $6000/year for a random code, and $12,000/year for a vanity code. These charges are on top of the normal per message fees. This does

This more of a best practices question. I''m implementing group functionality in a couple of applications. The typical method, using HABTM, where you create a group and add members, is typical. For example, Users, Groups and Messages. Does anyone prefer tagging instead? Any advice would be great! -- Lon Baker http://www.speedymac.com AIM: spdemac

I seem to have come to a strange problem getting started on rails. I had everything working in a virtual machine and then set up a seperate machine just for rails developement. It now seems something is broken a little. ruby 1.8.2, rails 0.10.1, postgres, using webrick: i created a table "users", then "generate scaffold User" view localhost/users works fine, shows the

Hola, Carlos. A mí también me resulta raro, porque no me pasa siempre. Es un poco aleatorio. Imagino que habrá alguna razón, y que el código de la página estará relacionado, claro, pero no consigo averiguar a qué se debe. Además las pruebas que hago me dejan todavía más perplejo.

Hi, I am using the package ncdf to create netCDF files and I want to mimic the the header of an exiting netCDF file created outside of R. Below is what the existing header looks like (part of it that is different): netcdf ccd1984_05_08 { dimensions: lat = 1974 ; lon = 1894 ; time = UNLIMITED ; // (1 currently) variables: int time(time) ;

Hope one of you could help with the following question/problem: We would like to explain the spatial distribution of juvenile fish. We have 2135 records, from 75 vessels (code_tripnr) and 7 to 39 observations for each vessel, hence the random effect for code_tripnr. The offset (‘offsetter’) accounts for the haul duration and sub sampling factor. There are no extreme outliers in lat/lon. The model

Hi lily, It's not too hard to do it using dataframes. Getting the indexing right is usually that hardest part: # these values are the centers of the black cells lat<-rep(28:38,11) lon<-rep(98:108,each=11) pop<-sample(80:200,121) # just use the data.frame function blackcells<-data.frame(lat=lat,lon=lon,pop=pop) plot(0,type="n",xlim=c(97.5,108.5),ylim=c(27.5,38.5),

Hi Jim, Thanks. It works. I now have more complex problems. If at each blackcell, there are two variables such as pop and mood. For each variable, there are daily records in one year, so 365 records for pop and 365 records for mood. The averaged values for the redcells should be daily records too. What kind of format do you recommend for this problem? Right now, I just get the latitudes and

a) you need to read the help pages on the paste function... more likely you are looking for the paste0 function because extra spaces will most likely break the GET request format. b) quotes do not become "stuck" as \" ... that is a visual representation intended to clarify that that quote is not terminating the string but is actually part of it. If you want to see the contents

Hi lily, You could also create "blackcells" as a dataframe (which is itself a type of list). I used a list as I thought it would be a more general solution if there were different numbers of values for different grid cells. The use of 1 for the comparison was due to the grid increments being 1. If you had larger or smaller grid increments, you would use the grid increment size for the

Hi, everyone I got some problems when trying to subscript the value of vector and list, by using calculated indices. Here is the vector I am generated lon<-rep(0,886);lat<-rep(0,691) for (i in 1:886){ lon[i]<-112+0.05*(i-1) } for (i in 691:1){ lat[i]<--44.5+0.05*(691-i) } For a given location of lon(xp) and lat(yp), I would like to calculate the position of them,

Hi, I'm trying to read a subset of a netcdf file into R, but although I'm relatively experienced using R, I'm still new to netCDF files, so this may be a very simple/stupid question! I've included an example of the type of file I'm looking at here. www.met.reading.ac.uk/~swp06hg/ccd1983_01-dk1_20.nc (~7Mb) It's a 2D array of the variable CCD along with its lat and
