Hi all, I try to use kernel 2.6.36.1 in HVM but building the drivers xen-blkfront, xenfs, platform-pci. I used Xen 4.0.2-rc1-pre and a DomU is a ubuntu 10.04 and I try with ubuntu 10.10. In boot I receive error "Cannot find a root partition /dev/xvda2" and a prompt (initramfs) appear. In dmesg (initramfs) appear: blkfront: xvda: barriers enabled (tag) xvda: xvda1 vbd vbd-51712: 16

Sorry for the contents not relating to R. Assume there are N i.i.d zero-mean complex gaussian random variables(RVs),as w(i),0<=i<N} with known variance,from which one can generate another N RVs,as R(0)=sum over i {w(i)*w'(i)} R(1)=sum over i {w(i+1)*w'(i)} ... up to R(N-1)= w(N-1)w'(i) where w'(i) is the complex conjugate of w(i). (from viewpoint of signal processing, R(i) a...

...vice with RCAPI Support. There are some devices (most of them isdn routers, like the famous Cisco 800 family) that support this protocol. It basically is an ISDN to IP gateway. There used to be software that used this technology to send and receive faxes, act as voicemail and even ISDN softphone. RVS-Com is such an example. This allowed you to have a single ISDN router shared between many computers running the software. Since the full ISDN functionality was available thru IP, it seems logic that the conversion to sip/IAX/whatever should be relatively simple (without having to deal with hardwa...

Dear R people, This is a possibly silly question, but the rgamma function takes the shape and scale arguments and simulates gamma rvs corresponding to those values, right? But the shape and scale parameters have to be positive, right? However, rgamma quite happily returns to me values for negative values of shape and scale, and in some cases returns negative values eg. > rgamma(1, 1, -1) [1] -1.011081 > rgamma(1, -1, -1) [...

Hi Folks, Given k RVs with MVN distribution N(mu,S) (S a kxk covariance matrix), let (w.l.o.g.) X1 denote the first r of them, and X2 the last (k-r). Likewise, let mu1 and mu2 denote their respective expectations. Then, of course, the expectation of X2 given X1=x1 is mu2 + S21*inv(S22)*(x1 - mu1) and the covariance...

I have seen people say both that rsync can efficiently copy truecrypt volumes. I got it working once with deltacopy but as I'm trying to get it to work from the command line, I cannot. It just transfers the whole file. I am using -rvs -inplace switches.

Full_Name: Uffe H?gsbro Thygesen Version: 2.2.0 OS: linux Submission from: (NULL) (130.226.135.250) Hello all. pbinom(q=0,size=0,prob=0.5) returns the value NaN. I had expected the result 1. In fact any value for q seems to give an NaN. Note that dbinom(x=0,size=0,prob=0.5) returns the value 1. Cheers, Uffe

(This is an extension of an email I sent earlier, but I'm not sure if it made it to the list or not.... I never saw it!) We seem to be accumulating Cisco 8XX series ISDN routers as DSL becomes more and more available in Australia and our clients upgrade. Does anyone know if those routers can make the ISDN channels available in a way that can be used by Asterisk? Preferably in a fairly raw

This is Off-Topic for Asterisk, but I wanted to get some feedback on headsets for Cisco 7940/7960 phones. We have about 10-20 people who wants/needs a headset for their phone & was hoping to collect some real-world input. Thanks!!

Hi, I have to draw samples from an asymmetric-Laplace-Normal distribution: f(u|y, x, beta, phi, sigma, tau) \propto exp( - sum( ( abs(lo) + (2*tau-1)*lo )/(2*sigma) ) - 0.5/phi*u^2), where lo = (y - x*beta) and y=(y_1, ..., y_n), x=(x_1, ..., x_n) -- sorry for this huge formula -- A WinBUGS Gibbs sampler and the HI package arms sampler were used with the same initial data for all parameters.

How does one define PDFs as yet undefined in R, such as the ex- gaussian, the sum of two RVs, one exponential, one Gaussian? The PDF would then be the convolution of an exponential PDF, dexp(), and a normal, dnorm(). Kindly cc me in your reply to r-help.

...related to R, and the only reason I am posting it to this list is that my implementation is using R. Let me describe my problem by giving an example, that is close to what I am trying to do. Suppose we are given a stream of pseudo-random numbers, U_1, U_2... intended to simulate a sequence of iid rvs from Unif[0,1], and a probability distribution (specified as a pdf f or cdf F), and are required to obtain a sequence of rvs X_1, X_2... such that X_i is a deterministic function of U_i. Let us further suppose that F^{-1} is difficult to calculate, so one does not simply do X_i = F^{-1}(U_i). Now...
