Remove
Hello,
I would like to remove some files which have the extension .test for
example (data1.test, data2.test ....).
Is there another solution to remove them instead of doing it one by one
?
Thanks for your help,

R and Browninan Motion/ Langevin Equation package
Hi,
I'm writing a short course tutorial to Browninan Motion/ Langevin Equation.
At the end of the theory section I wanted to add a short GNU R example, so the students can play a little around.
I already looked in the MASS book (by Venables and Ripley) but I couldn't find any Brownian Motion/ Langevin Equation package.
Are there any good packages or tutorials available which cover R and

simulating from Langevin distributions
Dear all,
I have been looking for a while for ways to simulate from Langevin distributions and I thought I would ask here. I am ok with finding an algorithmic reference, though of course, a R package would be stupendous!
Btw, just to clarify, the Langevin distribution with (mu, K), where mu is a vector and K>0 the concentration parameter is defined to be:
f(x) = exp(K*mu'x) / const where

file_column and has_many
I''ve been fighting with myself over this for the past week, and would

I''m wondering is there a way to load default data in the migration script?
So, for example I''m creating new table to store the order status, I also
want to pre-populate the table with some data from a sql file.
I have done a quick search on the list but cannot find anything.

weight scheme with document values
Hi guys,
I resently used xapian to sort some documents by distance between 2
points.
I implemented a MatchDecider which work well.
I now tried to implement a Weight scheme to put my document in ascending
order depending on the distance...
My information to calcul distance is in values in the document.
How I can access document values from Weight to be able to add some
sum_extra weight ??

frame of silence
Okay, you've answered part of my question, which is "What value equals
silence?". I assume then that a (decoded) frame of silence would be a
buffer the size of my frame (320 bytes) full of 0's.
Passing this frame (a frame of all 0's) through the encoder causes it to
blowup though..
In response to your answer below, I don't think I want to overwrite the

Best Practices: Splitting the "view model" from AR model
All,
I''m starting to see view state information creeping into my model class.
For example, I have text fields in my view that need to be set a certain
way depending on whether or not a checkbox is checked. And while the
values of these text fields ultimately do represent database columns
that are related to the backing AR object, the text_field values also
represent attributes on a

SPEEX on iPhone ?
Why don't you just try it?
From what others have been reporting, it shouldn't take you long to
get it running.
You can use speexenc and speexdec for testing.

SPEEX on iPhone ?
I can confirm that it will run in real time on iPhone if you compile
with FIXED_POINT defined; it will also run in real time if you have
FLOATING_POINT defined and disable 'Compile for Thumb' in the target's
build settings in xcode. Wideband works too.

File_column, RMagick, and watermarking
I''m working on a photo gallery and I''m using File_column to handle the
uploads of the files and create my thumbnails, but does anyone here have
any idea how to have a watermark (opaque text maybe) placed over one of
the versions? Any ideas on how to go about this would be great. Even if
it''s just straight RMagick code, that would be fine too.
Thanks in advance for the

correlated random effects in GLMMGibbs ?
Dear R-users,
I wondered if anyone has extended GLMMGibbs to include correlated
random effects, and if so, whether they would be willing to let me
use their code?
Jonathan Myles has no plans to extend glmm in this manner within the
foreseeable future.
With thanks,
Patty

frame of silence
Hi, I'm new to this list. I'm using Speex as the base codec in a voice
chat application (with DirectSound as the audio playback/capture
interface).
To help me debug some of my network-related issues, I would really like
to insert frames of "silence" into speech. Is there a convenient
function call or API call that takes in a buffer that is the size of a
frame and writes a

Getters and setters problem?
Hi list,
first evening of playing with rails, so please forgive me if I ask
something stupid. ;-)
I created a User model and tried to use ActiveRecord callbacks to
convert the password to sha1 just before saving it. For some reason
postgresql gives me a error because the given password is null. To
test even further I tried to change :login too, same error happens,
:login is empty too.

Is HABTM Dying?
For a while, I''ve been getting that HMT is replacing HABTM. It appears that
HMT can do all of what HABTM can do and more. The question is: Should I stop

For a given category, there are certain valid statuses

We are discussing the possibility of writing a very large application in

and have to share some common session data I''d like to get some
feedback on some possible ways of doing the following:

Howtos: Deploying Rails on Windows servers
After a lot of work (and much promising) I have written instructions
on various methods to deploy Rails applications in a Windows
environment. For those of you who are not stuck with Windows, this
won''t matter too much to you, but I think this is really useful for
those in Windows shops.
Topics covered:
* Serving Multiple Rails Applications on Windows with Apache and
Mongrel
* Integrate
