Problem with decoding number of codebooks
Hello,
I'm trying to write a Vorbis decoder (just as a hobby) but I've got a
problem with reading the setup header. According to the Vorbis
documentation the first data that should be read after the initial
'vorbis' string is an eight bit integer which when incremented by one,
contains the number of codebooks in the header. My problem is that
whenever I read this number it seems

Problems running virtual machines after an upgrade
Hi all,
I upgraded qemu-kvm and libvirt to the new versions

read codebook function
Anexed is my function for reading codebooks and the Vq Table. My problem is:
I read a codeBook number of 41, so i called this function above 41 times.
The firtst time, the sync patterns (BCV) is alligned correctly, so it reads correctly. the sencond time it is executed, the patter is not there anymore and there are only 8 BCV in my file.
function fReadBits1 is the same as the ogg's read bit

Bandwidth selection for ksmooth( )
Dear R Users,
Before running ksmooth( ), a suitable bandwidth selection is needed. I use some functions for this task and receive these results for my data:
width.SJ(y,nb=100,method="ste") : 40.25
bcv(y,nb=100) : 40.53
ucv(y) : 41.26
bandwidth.nrd(y) : 45.43
After implementing the function ksmooth(x,y, bandwidth= each of abovementioned bandwidths), I have some NAs

Multiple OCFS intances in the same LAN
Hi,
is it possible and safe to use more than one RAC-Cluster using OCFS in the same LAN?
I'm considering to following setup: a 2-node production and a 2-node test system, the production data is stored in an EMC Symmetrix and for the test-system the production data is copied once to a BCV disk internally. This will give me an new independant copy of the production disk with the same contents,

Clone a disk, need to change pool_guid
Hi folks,
I use an iSCSI disk mounted onto a Solaris 10 server. I installed a ZFS file system into s2 of the disk. I exported the disk and cloned it on the iSCSI target. The clone is a perfect copy of the iSCSI LUN and therefore has the same zpool name and guid.
My question is: is there any way to change the ZFS guid (and the zpool name, but that''s easy) on the clone so that I can

loop on list levels and names
Hi everybody!
To use some functions, I have to transform my dataset into a list, where
each element contains one group, and I have to prepare a list for each
variable I have (altogether I have 15 variables, and many entries per
factor level)
Here is some part of my dataset:

density estimation: compute sum(value * probability) for given distribution
Dear R users,
This is a KDE beginner's question.
I have this distribution:
> length(cap)
[1] 200
> summary(cap)
Min. 1st Qu. Median Mean 3rd Qu. Max.
459.9 802.3 991.6 1066.0 1242.0 2382.0
I need to compute the sum of the values times their probability of
occurence.
The graph is fine,
den <- density(cap, from=min(cap),
to=max(cap), give.Rkern=F)

using contrasts on matrix regressions (using gmodels, perhaps)
Hi,
I want to test for a contrast from a regression where I am regressing the columns of a matrix. In short, the following.
X <- matrix(rnorm(50),10,5)
Y <- matrix(rnorm(50),10,5)
lm(Y~X)
Call:
lm(formula = Y ~ X)
Coefficients:
[,1] [,2] [,3] [,4] [,5]
(Intercept) 0.3350 -0.1989 -0.1932 0.7528 0.0727

OCF2 and LVM
Does anybody knows if is there a certified procedure in to
backup a RAC DB 10.2.0.3 based on OCFS2 ,
via split mirror or snaphots technology ?
Using Linux LVM and OCFS2, does anybody knows if is
possible to dinamically extend an OCFS filesystem,
once the underlying LVM Volume has been extended ?
Thanks in advance

Unwanted behaviour of bw.nrd: sometimes, zero is returned as a valid bandwidth
Dear all,
Sorry if I am posting to the wrong place, but I could not find the link for
registration on the bug tracker, that?s why I am writing here.
I think there is inconsistency between two R functions from the stats
package, bw.nrd0 and bw.nrd.
Consider the following vector:
D <- c(0, 1, 1, 1, 1)
bw.nrd(D) returns zero bandwidth for this object even without a warning.

Help w/ density() usage
Dear All,

I'm trying to implement a modern-version of a (classic) "several-step protocol" in Fishery Biology (due to Bhattacharya, 1967): analysis of length-frequency distribution of fish larvae to id cohorts and later estimate growh rates!

kernel density estimates
Dear All,
I have a variable q which is a vector of 1000 simulated positive values; that is I generated 1000 samples from the pareto distribution, from each sample I calculated the value of q ( a certain fn in the sample observations), and thus I was left with 1000 values of q and I don't know the distribution of q.
Hence, I used the given code for kernel density estimation to estimate the
