localhost/PING is CRITICAL
Hi all,
I've recently switched to the latest rt kernel
available from http://people.centos.org/hughesjr/kernel-rt
And one of the two problems I'm having with this new kernel
is that the logs have been flooded with nagios alerts
which indicate high percentage (50-60) of packet loss
when pinging localhost. The problem shows up several hours
after the system reboot.
Any ideas on what might be wrong and how to fix this
on a running system?
Are there any current plans to integrate MRG Realtime
into CentOS project?
Thank you,
Sasha

Integer bit size and the modulus operator
I am a statistician and I come up to an interesting problem in
cryptography. I would like to use R since there are some statistical
procedures that I need to use.
However, I run into a problem when using the modulus operator %%.
I am using R 2.2.1 and when I calculate modulus for large numbers (that
I need with my problem) R gives me warnings. For instance if one does:
a=1:40;
8^a %% 41

[PATCH] (4/4) add loss option to network delay scheduler
This enhances the network simulation scheduler to do simple random loss.
The loss parameter is a simple 32 bit value such that 0 means no loss, and
0xffffffff is always drop. I have a new version of the tc command which takes
care of conversion from percent to this value.
Same patch for 2.4 and 2.6

histogram labels
...ust a quick one, hopefully. I have a histogram made from the method
'hist()'. How do I get labels on the bars? Such that the bars will have
the x axis on the bar, not the frequency of the point but the number of
the point itself. To make a quick summary, I want the the numbers from
'losses' (below) to be on the bar's.
Thanks,

Packet Loss question
Hello all,
I know that SPEEX has a mechanism to handle packet loss.
I see there is some handling for packet loss implemented in speexdec.
I want to know, if in my own application should i also implement such
packet loss handling or is it taken care of within the decoder?

unexpected behavior of rpart 3.1-43, loss matrix

I just noticed that rpart behaves unexpectecly, when performing
classification learning and specifying a loss matrix.
if the response variable y is a factor and if not all levels of the
factor occur in the observations, rpart exits with an error:

Some scratches with beta3
Hi,
I have included the oggvorbis encoding and playback stuff in the
Linux-Mandrake distro back in August 2000. At that time I put the "nightly
CVS" version, which worked just fine.
Then on Mon Nov 27 I noticed some RPM's labelled "1.0beta3" on the website
so I upgraded with these ones.
Since then we have had some serious problems in encoding: approx 20% of

IAX2 tolerance on packet losses
Hello,
I'm experiencing some problems with running IAX2 protocol on quite
reliable link with G729A codec. My customer has 2mb FR link to the
Internet used in about 20%. Ping statistics:
50 packets transmitted, 49 received, 2% packet loss, time 49496ms
rtt min/avg/max/mdev = 9.308/13.126/33.307/4.851 ms
Everything would be great, but the quality isn't good enough. I have
2mb/512kb DSL line,
on which voice calls are working muuch better.
I've checked it on many ways. Hping tells me, that the average UDP
packet loss rate is...

packet loss
Hi,
Something strange is happening at my place: I have lots of packet loss
in my tinc vpn.
Network layout:
laptop --- wifi --- other pc
ping from laptop to other pc OUTSIDE tinc: 0% packet loss
ping from laptop to other pc VIA tinc: 50% packet loss
What could be the cause of that?

over/underestimating expected packet loss
I'm curious what happens if you feed an inaccurate value to 'expected loss'?
Channel loss rate isn't always easy to measure, esp. in real time.
I'm trying to figure out, ultimately, is it a better strategy to put the worse case expected loss in there, or more like the best case?
(dealing with audio/full bandwidth here)
thanks,

PLC (Packet loss cancel) questions
Hello
I've been using VoIP over a not so reliable net: I usually
get a 5% to 10% packet loss and a very high jitter. I tried
several codecs and parameters, and the only thing left to
test is PLC (Packet Loss Cancellement).
Have the astesrisk and digium people implemented PLC?, Are
they implmementing it now? and, if not, Where can i find an
implementation?
Thanks in advance

NAT traversal packet loss measurement
How can one measure the effect of NAT traversal packet loss?
We currently have no solution for NAT traversal for our SIP clients. There
is no doubt that packets are getting lost. What is not clear is how much
damage this does. On the face of it, everything seems fine. Could this be
so? Perhaps we're suffering a degradation in quality or our call setup t...

changing the loss function in the logistic regression?
Hi all,
Is there a way to change the loss function in the logistic regression?
Or we could provide a customized loss function in the logistic
regression so we could use that loss function in the Cross Validation

Thanks a lot!

Question about rpart decision trees (being used to predict customer churn)

the decision trees created are not effective because they are not able to
recognize factors that influence churn. I have created an example situation
below. What do I need to do to for rpart to build a tree with the variable
experience? My guess is that this would happen if rpart used the loss matrix
while creating the tree.
> experience <- as.factor(c(rep("good",90), rep("bad",10)))
> cancel <- as.factor(c(rep("no",85), rep("yes",5), rep("no",5),
rep("yes",5)))
