New package: dtw - Dynamic Time Warping
Dear R community,
I would like to introduce the package "dtw" for computing Dynamic Time
Warping (DTW) alignments and related algorithms on timeseries.
The DTW algorithm computes the time axis stretch which optimally maps one
timeseries (query) onto another (template); it outputs the resulting
cumulative distance between the two inputs, which is frequently used for
classification and

fast time series similarity (iSAX, UCR DTW, UCR ED) implementations for R?
Hello.
I'm looking for a fast way to group by similarity many (5-10k) long
(2-10k points) time series.
Using PAM on distance matrix obtained via as.dist(1-abs(cor(data)))
produces usable results but it's rather slow and doesn't catch slightly
shifted time series.
DTW implementation from package 'dtw' is orders of magnitude slower even
with global window constraints which

multivariate group means
Hello,
I look for a simple command computing multivariate group means and
returning an object of class "matrix" rather than "list". Does any
such function exist in standard packages?
I'm beginning with R, so I'm sorry if the solution is trivial.

Mouse warping, toggle option
One of the nagging issues that has been around for awhile with wine is "mouse warping"
In some cases it doesn't place nice with the house environment, in other cases it doesn't play nice with the game, and overall it's a bit of an annoyance.
Would it be possible to introduce an option to wine that would allow one to select whether warping is used (maybe a checkbox for

How to find a shift between two curves or data sets
Hello,
I have a issue here!
I need to find the offset or shift between two data sets.
Each data set does not start nor end at the same time and dont even have
the same sampling interval (which by the way isn't constant in any of
the data set).
It must be known that the data expressed in both the data set are
comming from the same sensor so they should be the same!

how to rotate elements in a vector and points in a plane
Dear R-helpers,
I need two simple functions, I guess they exist in R, but I am unable
to find them.
The first function should cyclically rotate elements in a vector.
("guyrot" in the package "wavethresh" should do it, but there's some
problem with its loading)
The second function should rotate points in 2D by a given angle (about
the defined point).
Thanks for any advice

[LLVMdev] 32-bit in-tree Polly build with CMake
Hi,
I was having troubles building LLVM with Polly in-tree using CMake
with LLVM_BUILD_32_BITS on. Turns out CMake considers LLVMPolly a
module, not a shared library, and LLVM_BUILD_32_BITS only makes
provisions for the EXE and SHARED linker flags.
Possible fixes (pick one):
1. Change cmake/modules/HandleLLVMOptions.cmake to append -m32 to
CMAKE_MODULE_LINKER_FLAGS as well if LLVM_BUILD_32_BITS

Mahalanobis Distance
Hello R helpers,
I'm trying to use Mahalanobis distance to calculate distance of two time
series, to make some comparations with euclidean distance, DTW, etc, but I'm
having some dificults.
I have, for example, two objects:
s.1 <- c( 5.6324702, 1.3994353, -3.2572327, -3.8311846, -1.2248719,

Building a Search Page as part of CRUD
I''ve been experimenting with Rails over the past couple of days and
have come across something that seems harder than it should be. In
previous frameworks I have used (WebObjects, php) a full search page
(which leads into a list view populated with search results) was part
of the CRUD that was either dynamically or statically created after
specifying table/object schema. In

[LLVMdev] [RFC] Fix leading and trailing spaces
Hi,
I am writing tool to simplify automated refactorings. One of
prerequisites is have clean codebase, so a refactorer can be simple and
created formatting inconsistencies can be eliminated by formatter.
My plan to keep codebase clean is first run a cleanup systemwide, then
keep it by hook/ periodicaly rerunning cleanup.
I put it for now here.

XEN for Debian Installer development
Hi,
I''m tweaking Debian Installer and I use VWware to test it. I am courius if
XEN could be suitable for the testing of Debian Installer. Is there anybody
who tried it?
What I need is that I make an ISO image which is booted in virtual machine
(DomU). The virtual machine handles an ISO image as an ordinery CD-ROM.
Then I need to connect to several consoles (Like Alt+F1, Alt+F2, in

[LLVMdev] Heap memory allocation
I'm implementing a lazy functional language and I need to allocate nodes on
the heap. From what I've read LLVM supports only the 'alloca' instruction
which allows to allocate memory on the stack. Is this true and and if so,
what is the preferred way to solve my problem?

Bug#573210: tracedumps from vcpus when domU crashed
Hi,
today I had catched one domU crash and taken tracedumps from xen vcpus,
see attachment. Hope it could help. Today I've got some problems with
clocksource so I've upgraded to last 2.6.26-xen-amd64 kernel from
security so I'll confirm if problem occurs there or not in some days.
