I''m a newbie attempting to get a custom fact distributed to clients. I''ve followed the instructions at http://reductivelabs.com/trac/puppet/wiki/AddingFacts and based my first fact on a simple recipe. I''m having at least one problem and possibly more. 1) Puppet/facter fails to load the custom fact, complaining that "non- sh interpreters are not currently

hi, I rewrote escape, unescape, and query_parse in a C extension. http://s3.amazonaws.com/four.livejournal/20070922/http_helpers.tar.bz2 Here are some sample benchmarks (the benchmark script is included in the package) user system total real escape: Single long Mongrel: 1.680000 0.020000 1.700000 ( 1.837793) HttpHlp: 0.030000 0.010000 0.040000 ( 0.036590)

Hey all, here is a less hacky version of the query string C extension I posted before. http://s3.amazonaws.com/four.livejournal/20070927/qsp.tar.bz2 It uses an http11-like interface to the state machine. the escape/unescape functions are also slightly more libraryish. again, here is the about benchmark results. it seems to be about 10 times faster than the ruby functions. i''ve seen

Hi all, Looking at the IO.readlines source in io.c, it looks to me like they grab 8k chunks, split on the input record separator, and buffer accordingly. Since it looks like ReadFileScatter() does some of that work automatically (in page file sized chunks), I thought I''d give it a try. Here''s what I''ve got, but it doesn''t work. I have an incorrect parameter

I recently had the chance to read a book explaining how to use ChatGPT with a certain programming language. (I'm not going to describe the book any more than that because I don't want to embarrass whoever wrote it.) They have appendix material showing three queries to ChatGPT and the answers. Paraphrased, the queries are "if I throw 2 (3, 4) fair dice, what is the probability I get

I have a model object that acts as a list. The position of each object is determined by two factors: number of votes ascending and age of object descending. When a user adds or deletes a vote I need to quickly update the associated model object''s position. Right now this is done with the following method: def update_position position = nil Bug.find(:all, :order =>

Fellow R Users: I'm not extremely familiar with lda or R programming, but a recent editorial review of a manuscript submission has prompted a crash cousre. I am on this forum hoping I could solicit some much needed advice for deriving a classification equation. I have used three basic measurements in lda to predict two groups: male and female. I have a working model, low Wilk's lambda,

Hi. Im exploring `opt -reg2mem` output for a simple C program (actually, that is this snippet: http://rosettacode.org/wiki/Dining_philosophers#C - compiled with clang -O1) and got two questions regarding this pass. 1. How would I tell which memory locations were introduced by the pass, and which memory locations were present in the original program? After a brief diffing of .ll files, I'd

Hello, all. I released AjpRails 0.1.0. AjpRails is a script for running Ruby on Rails. Rails this script runs uses AJP13(Apache JServ Protocol 1.3) instead of CGI or FastCGI, to cooperate with your HTTPd. Its RubyForge project is: http://rubyforge.org/projects/ruby-ajp/ Project home page is: http://ruby-ajp.rubyforge.org/wiki/wiki.pl Now, AjpRails is slower and much more unstable than

I am trying to add data from a form, and the rails doesn''t appear to be making any effort at all. I''ve put deliberately erroneous data, but still nothing. All the development log shows is this. This is the code in use - based on the example from Rails book def add_customer_admin if request.get? @login = CustomerAdmin.new else @login =

Hi R experts, I have the following timeseries data: #example data structure a <- c(NA,1,NA,5,NA,NA,NA,10,NA,NA) c <- c(1:10) df <- data.frame(timestamp=a, sequence=c) print(df) where i would like to linearly interpolate between the points 1,5, and 10 in 'timestamp'. Original timestamps should not be modified. Here the code I use to run the interpolation (so far): # linear

Dear R-help list, I'm trying to overlay a number of data objects in a plot. Following an earlier example on the list I've created an empty plot as follows > xlim <- range(as.numeric(c("0","10000"))) > ylim <- range(as.numeric(c("0","25")) ) > plot(NA, xlim=xlim, ylim=ylim, xlab="distance", ylab="semivariance")

Hello! Someone know what are the difference between R and S-PLUS in the density() function? For example, I would like to reply this simple S-PLUS code in R, but I don't understand which parameter I should modify to get the same results. S-PLUS CODE: density(1:1000, width = 4) R-CODE: density(1:1000, bw = 4, window = "g", n = 50, cut = 0.75) I obtain the same x values, but
