Hi, Some random sample of VS warning: Lot of 64 bits conversions: AsmPrinter.cpp ..\..\lib\CodeGen\AsmPrinter.cpp(277) : warning C4244: 'initializing' : conversion from 'uint64_t' to 'unsigned int', possible loss of data ..\..\lib\CodeGen\AsmPrinter.cpp(614) : warning C4244: 'argument' : conversion from 'uint64_t' to 'int', possible loss of data

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

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 one

Hi all, I recently wrote some code to store a number of polynomial models in a list and return this list. The model is returned fine, but when I make a subsequent call to predict(), I have an error. The code for polyModel selection is listed at the end of the email. Here is an example of the error: > poly.fit <- polyModelSelection(x,y,10,F) > for (d in 1:4) { + lm.model <-

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 Signed-off-by: Stephen Hemminger <shemminger@osdl.org> diff -Nru

...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, Paul hist<-hist(losses, breaks=length(losses)/2, col="red", main="Frequency of the first neutral losses > 5", labels=T, xlim=range(0:150)) > length(losses) [1] 3096 > losses[1:50] [1] 7.835622 7.058985...

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? I want to test my SPEEX application for GNU Radio for some packet loss,if i just simulate a packet loss mechanism, will it work

Hi, 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: > df=data.frame(attr=1:5,class=factor(c(2,3,1,5,3),levels=1:6)) > rpart(class~attr,df,parms=list(loss=matrix(0,6,6))) Error in

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 the WAV

Hi All, could anybody help me to understand what is this error means ? mydata=read.table("C:/Documents and Settings/angieb/Desktop/CommercialGL/cl_ilf_claimdata.csv",header=TRUE,sep=",") > names(mydata) [1] "ILFTable" "liabLimit" "AnnAggLimit" "DedAmt" "Loss" "TIL" >

Hi, I am using netem to add loss and then adding another qdisc within netem according to the wiki. Then i want to change the netem drop probability without having to delete the qdisc and recreate it. I try it but I get invalid argument: thorium-ini hedpe # tc qdisc add dev ath0 root handle 1:0 netem drop 1% thorium-ini hedpe # tc qdisc add dev ath0 parent 1:1 handle 10: xcp capacity 54Mbit

...issions ability? I've setup jitter with default settings from iax.conf, but the quality remains almost the same - it's still tooo jiiiiitttteery every few seconds. I ran out of ways to test it. The conclusion remains the same - delays and delay changes should be good enough, but the packet losses remain too. I see some VNAK requests in my log files, but no more than 3-4 during ~40 seconds connection. So should I fight the packet losses or tune my iax.conf options? -- Redargs, Ernest Raspberry

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? Folkert van Heusden -- Always wondered what the latency of your webserver is? Or how much more latency you

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, Marc

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 -- Jorge

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 times could be improved. How can we

Buenos días, estoy intentando reproducir el script de este github: http://uc-r.github.io/iml-pkg#interactions Todo iba bien hasta que en el 6º panel me encuentro esto: For any given loss function do 1: compute loss function for original model 2: for variable i in {1,...,p} do | randomize values | apply given ML model | estimate loss function | compute feature importance

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 in logistic regression? Thanks a lot!

Hi, I am using rpart decision trees to analyze customer churn. I am finding that 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
