Debootstrapping a rootfs for Xen on FastModels A15
Hi,
I''ve tried several different approaches to debootstrap a working
rootfs for with a Cortex A15 model ( FastModels ) and Xen but still
face some issues.
Some information on my setup.
For a Dom0 kernel I''m using the latest version from
git://github.com/torvalds/linux.git, I attached my config as it might
be of some use for others. I''m using the latest Xen unstable

help - Theora/Vorbis/Ogg, ogmmerge and ffmpeg2theora
Hi,
I'm probably being fairly stupid. But I did the following, starting with
the following two files:
# tcprobe -i vts_01.m2v
[tcprobe] MPEG elementary stream (ES)
[tcprobe] summary for vts_01.m2v, (*) = not default, 0 = not detected
import frame size: -g 720x576 [720x576]
aspect ratio: 16:9 (*)
frame rate: -f 25.000 [25.000] frc=3
# tcprobe -i vts_01.m2a

TS from DVB-T to Theora + Vorbis
Hello,
Could you kindly point me to some instruction, how to encode demuxed
files (.m2v and .mp2) to .ogg (Theora + Vorbis)? I was trying to use
ffmpeg2theora, but I don't know, how to put two files to ffmpeg2theora
(one audio an one video) and did not found, how to mux them into one
file?
Exist a way, how to do two pass encoding?
I'm using Ubuntu Fiesty Linux.
Thank you,

For Loop performance
Hello,
Newbie question and hope you can help .
I have two vector V1 and V2, where length(V2) = length of (V1) * 2;
length(V1) ~ 16,000.
For each member in V1, I need to compare 2 element of V2 for equality
i.e.
for (I in 1:length (V1)) {
if ( v2[i] == v1[i] & v2[i+1]==v1[i] ){
statement_1
statement_2
.
}
}
This for-loop is too slow

ASUS M2V mobo issues
We have 4 systems supported by ASUS M2V mobos with AMD2 cpus on board. No
we haven't gotten CentOS of any flavor to work yet. Yes, we did load Fedora
Core 6 and it worked, with respect to the SATA driver only. There is a
RAID, Audio and LAN driver for Linux that comes on the M2V mobo CD. The
audio driver installs and works fine on FC6. I've read many of the messages

[PATCH v2] arm: introduce a DTS for Xen unprivileged virtual machines
Given that the xenvm machine is based on vexpress but with an extremely
limited selection of peripherals (the guest is supposed to use virtual
devices instead), add "xen,xenvm" to the list of compatible machines in
mach-vexpress.
Changes in v2:
- remove include skeleton;
- use #address-cells = <2> and #size-cells = <2>;
- remove the debug bootargs;
- use memory@80000000

ASUS M2V?
Anyone use the ASUS M2V motherboard. This is the current board I am
looking at for AM2/HVM because of the number of slots.
Thanks,

xen does not work with amd64 kernel but works with 686
Hello,
I have problems running Xen (from Debian 7, i386 userspace) on Asus P3-AE5
system (M2V-TVM board) with Athlon 64 3000+ CPU (AM2, 1.8GHz).
In short, Xen is not accessible from amd64 Linux kernels but works fine with
686 kernels.
Long version:
xen-system-i386 (4.1.4-3+deb7u1) works fine with linux-image-3.2.0-4-686-pae

loading libraries on MPI cluster
Dear R-users,
we are using library(snow) for computation on a linux cluster with RMPI.
We have a problem with clusterEvalQ: after launching clusterEvalQ it seems
loading the required library on each node but if we type a function
belonging to the loaded package R doesn't find it.

new version of abind()
There is a new version of the abind package on CRAN (abind_1.1-0). abind()
is a multi-dimensional generalization of cbind() and rbind() -- it can bind
multiple 2-d matrices into a 3-d array, or bind 3-d arrays together, etc.
In this new version the behavior of the function abind() has been enhanced
slightly (it can now accept a list as the first argument, removing the need
to use do.call()

Installing packages from source code
Hi everybody,
I have trouble in installing packages from source code by following Section
5.1 in manual R-admin.pdf . I am using R 2.1.0 and Win NT.
Following the Windows toolset section in the manual, I download the tool
set package from: http://www.murdoch-sutherland.com/Rtools/tools.zip

I also downloaded Perl (Windows Port) and installed it.

install packages from intranet
Hi,
I'm new to R. Apologies if this is a simple query, I've searched the mailing lists and docs but can't find a solution to my problem.
I'm trying to make some packages available on our intranet. During development the 'intranet' is a webserver running on localhost.

rbind to array members

Tony Plate's message that what I'd like to do might not be possible)

I've looked into using abind() but it seems I might not understand it properly.
I can build my 2 table array and insert a row into each table using:

mixed interlaced content and ffmpeg2theora
dv file from minidv camera - interlaced.
small dv created by imported jpeg images - not interlaced.
seems that when I use ffmpeg2theora with deinterlace switch and reduce
size, it works. But when the only reduction I am doing is to width
(720x480 -> 640x480) the encoder ignores the naturally interlaced bit
and uses the last de-interlaced frame.
Since the small bit made from jpegs is a dv

several bugs (PR#918) lists and matrices
### I got bit again by the same bugs I wrote about a year ago.
### The bugs are related to matrices and arrays of lists.
### 1. There is a clear inconsistency in how R handles two
### functionally equivalent statements.
### array() is able to take a list and create a matrix.
### matrix() is unable to create that matrix.

do.call() and aperm()
Hi everyone
I've been playing with do.call() but I'm having problems understanding it.
I have a list of "n" elements, each one of which is "d" dimensional
[actually an n-by-n-by ... by-n array]. Neither n nor d is known in
advance. I want to bind the elements together in a higher-dimensional
array.
Toy example follows with d=n=3.

Generalised rbind/cbind
Dear list,
Is there a generalised form of rbind/cbind for combining
matrices/arrays into higher-D structures? ie. if I have:
a <- matrix(2,2,2)
b <- matrix(3,2,2)
how can I get
array(rep(c(3,2), each=4), c(2,2,2))
?
It seems like this would be the job of a generalised abind function:
abind(a,b, along=1) == rbind(a,b)
abind(a,b, along=2) == cbind(a,b)
abind(a,b, along=3)
