similar to: (koans) another problem (syntax error)

hello, Im still working on ruby koans. Now I have to do some sandwhich code. The exercise looks like this : require File.expand_path(File.dirname(__FILE__) + ''/edgecase'') class AboutSandwichCode < EdgeCase::Koan def count_lines(file_name) file = open(file_name) count = 0 while line = file.gets count += 1 end count ensure file.close if

Hi, I just encountered what I thought was strange behavior in MDS. However, it turned out that the mistake was mine. The lesson learned from my mistake is that one should plot on a square pane when plotting results of an MDS. Not doing so can be very misleading. Follow the example of an equilateral triangle below to see what I mean. I hope this helps others to avoid this kind of headache.

For those not familiar Ruby Koans is a fantastic platform for teaching many of the basics of programming in the Ruby language. It uses unit tests written for methods each of which describe a component of the Ruby programming language. http://rubykoans.com/ The koans platform has become popular enough that it has been translated to a few other popular languages.

Suppose I have three numbers p1, p2, p3 with 0 <= p1,p2,p3 <= 1 and p1+p2+p3=1, and a function f=f(p1,p2,p3) = f(p1,p2,1-p1-p2). How to draw a contour plot of f() on the p1+p2+p3=1 plane, that is, an equilateral triangle? Functions triplot(), triangle.plot(), and ternaryplot() give only scatterplots, AFAICS -- Robin Hankin Uncertainty Analyst National Oceanography Centre,

I have a function for plotting soil texture that I am having a problem with. The function is: plot.psd <- function(sand, clay, ...) { conv.ter <- function(x, y) { x.con <- 100 - x - y*cos(1/3*pi) y.con <- y*sin(1/3*pi) data.frame(x=x.con, y=y.con) } plot(conv.ter(sand, clay), xlim = c(0,100), ylim = c(0,100*sin(1/3*pi)), axes = FALSE, xlab="",

Hi all, I am working on a filled contour plot which shows a triangular matrix data set (as shown below). Is there a possibilty to draw a triangular filled contour in a equilateral triangle (like a ternary plot)?

Hi All, Does anybody have any tips or suggestions for migrating from a CentOS + Xen setup and using cobbler/koan [1] for VM provisioning to an XCP setup using XCP templates (or similar) to provision VMs? cobbler/koan make use of kickstart, which It looks like XCP can do as well. Mainly, I am wondering if converting the cobbler profiles could be done automatically and reliably? Any comments,

Hi, We are trying to use clang as a drop-in replacement for the gcc come with Android NDK. I found that MC/ELF doesn't not handle Thumb functions properly, e.g., bit 0 of the function name in the .symtab is not set to 1, and some thumb instructions are not generated correctly, e.g., the addresses for tBL/tBLX are not calculated right. With that attached patch, we can compile and run some

Hi Koan, Have you tried to run Intel and other platform tests? I feel uncomfortable with so many changes in generic MC/ELF regarding specific ARM support... not to mention the magic variables on shifts... ;)

Hi, Simple question that I can't track down any notable discussion about, let alone an answer... Is it possible to define what the "default" nic and storage types are? I am deploying images out of cobbler using koan and all of them are running virtio wherever applicable, but this is not the default, and at present there is no way within koan or cobbler to define what type of

Hi Koan, In general, this looks OK to me. Please split the patch into separate pieces, one for each issue you're addressing, though. From your description, it sounds like this should be 4 patches. That way we have a cleaner revision history in svn. -Jim On May 12, 2011, at 10:42 PM, Koan-Sin Tan wrote: > Hi, > > We are trying to use clang as a drop-in replacement for the gcc come

Renato, The result of running 'llvm-lit $LLVM/TEST/MC" is: Expected Passes : 330 Expected Failures : 20 Actually it passed "make check", no unexpected result.

Using the koan command, a VM can essentially request that it be reprovisioned. Is there any way for a VM to request that it reboot from a snapshot taken with virsh?
