find similarity between two spectral profile
Hi,
I'm Pina and I'm a student in geology. I'm working with spectral profile of
sand and I have to find the similarity between one spectral profile selected
by hyperspectral image anche one that I created to mix different percentage
of 4 mineral component. I have to find the best mix of percentage of this 4
mineral in order to have the best likeness with the spectral profile chose

Asterisk Billing
Hello,
I'm checking some Billing Software for Asterisk. In opensource I only
know (the name, I haven't used) AstBill. What other software should I
check with similar capabilities?
Thank you!

UID to file?
Hello,
In the past I was in a situation that given an email UID I wanted to
know which file in the Maildir directory this UID was saved.
I did a small parser for $HOME/Maildir/dovecot-uidlist where, if the
file had:
1000 W1838 S1796 :1557351041.10447_1.example
I would ask for the UID 1000 and would return
:1557351041.10447_1.example (and I knew that it was in
$HOME/Maildir/new)
Is there any

PLS Error message
Hi,
I work with hyperspectral remote sensing data and I try to built a pls
model with this data. I already built the model but if I try to
calculate the RMSEP and R2 with a test data set I get the following
error message:

GlusterFS Fuse client hangs when coping large files
Hello,
I?m having some weird problems while coping large files (> 1GB) to a GlusterFS through a Fuse client.
When the copy is done using the cp command everything is fine, but if I use a Java program, the GlusterFS Fuse hangs.
The kern.log shows timeout for the Java program and the Fuse client.
Anyone have experienced this behavior?

Error: package 'lsei' is not installed for 'arch=i386'
Hi guys,
I am having problem loading a package that I have installed. I have searched
some old thread but they were no help in terms of solving the problem.
I uninstalled every possible component of R and installed R 2.13 and
followed the R-faqs installation steps. Then I installed the package (lsei)
from local zip file which was installed successfully but can not be loaded

Package boot, funtion cv.glm
Hey all,
I need some help with a cross validation. I'm new with R and as well with
statistics. I had a group work to create a tool for remote sensing class
that extracts the best bands of hyperspectral satellite images that describe
vegetation. Its a regression between a linear function of using a normalized
differenced index (i-j)/(i+j) while i and j are the bands (in the data these

MeetMe CPU resources
Hello,
We would like to have a conference with 15 users aprox. We think that
Pentium 4 3GHz and 1GB of RAM should be enough. Only Asterisk running.
We wonder if somebody has some other experience, good or bad.
We will use Asterisk 1.2 (it is a small and short project for only
this).
Thanks!

SMS in Spain (it seems Protocol 2)
Hello,
(I have asked it some time ago in Asterisk-es mailing list, so excuse me if
anybody receive it twice.)
I am trying to send SMS in Spain using landlines. It seems that
app_sms.c only handles Protocol 1, but Spain and Italy are using
Protocol 2.
I have been searching in Internet without any results... anybody is
sending SMS from Asterisk (or any method) using Protocol 2? (so, it

download Dovecot emails over rsync (done!), possible alternatives
Hello,
Apologies for the extra long email. It's a situation with a solved
problem and I might need to solve it again, I'd like to have some
feedback.
Two years ago, in a trip around the Antarctic with a very limited
communication I deployed a mail system based on Postfix+Dovecot. I need
to do something similar again and I used a "hack" that I thought that I
might avoid (that

whisper chanspy in asterisk 1.2
Hello,
I would like to have "whisper" channel spy (not private whisper) in
Asterisk 1.2. I see here:
http://www.the-asterisk-book.com/unstable/applikationen-chanspy.html
That is only available for Asterisk 1.4.
I wonder if there is any way to emulate it in Asterisk 1.2. For example,
to "join" two calls: one to use a private whisper and other one to use
a normal chanspy.

channels to destroy
Hello,
In a couple of Asterisks, after type "sip show channels" we have a lot
of these:
IP_PEER dst_number something 00102/00103 unkn No (d) Rx: BYE
IP_PEER dst_number2 something2 00102/00103 unkn No (d) Rx: BYE
We are using ASterisk 1.2.x
When I say "a lot" I mean more than 180, more than 230, etc.
Is it normal?
How we can remove it?
Thank you very much,

SIP Reason
Hello,
I'm sniffing traffic between Asterisk and a Softswitch. I see that, in
"Decline" SIP packages, there is a header called "Reason" and I would
like to access to the content of this header from Asterisk.
How I can access to Reason header content?
I would like to access here using ASterisk 1.4 and 1.2, but if it's only
with Asterisk 1.4 will not be a big problem.

evaluation of discriminant functions+multivariate homosce dasticity
While I don't know anything about Box's M test, I googled around and found a
Matlab M-file that computes it. Below is my straight-forward translation of
the code, without knowing Matlab or the formula (and done in a few minutes).
I hope this demonstrates one of Prof. Ripley's point: If you really want to
shoot yourself in the foot, you can probably program R to do that for you.

Solve linear program without objective function
Dear R-users,
i try to solve to following linear programm in R
0 * x_1 + 2/3 * x_2 + 1/3 * x_3 + 1/3 * x_4 = 0.3
x_1 + x_2 + x_3 + x_4 = 1
x_1, x_2, x_3, x_4 > 0,
x_1, x_2, x_3, x_4 < 1
as you can see i have no objective function here besides that i use the
following code.

Asterisk scalability
Hello,
I wonder how Asterisk scales when we increment the Core's or CPU's of
one computer.
I see that Asterisk is only one process (I guess that it uses threads).
But because Asterisk is only one process, this process is always
executed in the same CPU. So we can have a 8 Cores server, with one Core
running Asterisk, another Core running operating system stuff/other
small daemons and 6
