[PATCH 0/2] Runtime configuration of HTB''s HYSTERESIS option
The HTB qdisc has a compile time option, HTB_HYSTERESIS,
that trades accuracy of traffic classification for CPU
time. These patches change hysteresis to be a runtime
option under the control of "tc".
The effects of HYSTERESIS on HTB''s accuracy are significant

gypsy, and not only
hi
i ve seen one of your replies here and i saw that you receomend 2
modifications in the kernel files in order to improve htb.
first in pkt_sched.h, changing PSCHED_JIFFIES to PSCHED_CPU.
and then, sch_htb.c, changing HYSTERESIS from 1 to 0.
is it that simple?
i mean i just change these here variables and i get better results?
i ve done a search and found the first file in 3 locations. where

Recommended minimal amount of free space to keep?
Hello.
So, LVM is cool, having different partitions for different stuff is
cool, and of course Ext4 is cool and *reliable*.
So, we create some logical partitions and put ext4 on them,
reserving LVM space for growing those partitions or even making new ones
later.
The thing is, I would like to keep every filesystem as small as it
can be, but without degrading the performance too

UPS restart delay
Hi,
I have an Eaton/MGE EX 11 RT UPS (uses the mge-shut driver) and while I was testing it I found that it would turn back on straight after power was restored.
I had a look but I couldn't find a setting which would let me tell it to charge to (say) 50% before turning the load back on.
Does anyone know if this is possible? A setting like this would provide some hysteresis for successive

HTB dequeueing in pairs fixed
I posted earlier when I noticed that htb was releasing packets in pairs,
even though my burst/quantums were 1 pkt.
To fix I set HTB_HYSTERESIS 0 in net/sched/sch_htb.c .
This gives a noticable gain in upstream worst case latency, for me with
256kbit/s up I used to see +90 sometimes, now it''s +45. For the many who
have 128 up it should limit them to +90 rather than +180.

choice of an HMM package
We are trying to build a human respiration model.
Preliminary analysis of some breathing signals has shown that humans breathe
through switching among
a finite number of patterns.
Hidden Markov seems to be the right approach. Since most of our code is
written in R scripting language, finding an R package implementing an HMM
that we can use for our prototype would be very helpful.
I have been

depmixS4+transition
Dear helpers,
is there any possible that transition (in depmixS4) is in scale of two
variable, e.g transition=~scale(x1,x2)?
If it can be, how transition of two variable (covariate time) can be worked
in depmixS4-hidden markov model for time series.
Many thanks,
nglthu

voice activity detection
Yes, you can use it independently by using speex_preprocess().
This function can do noise removal, AGC, and VAD. I've been
using it to do all three and it usually works very well. There
can be a train going by outside, producing lots of sound that
makes it through the noise filter, and yet the VAD knows it's
not speech.
However, sometimes the VAD seems to get into a bad state and

Re: Recommended minimal amount of free space to keep?
You will get better long- term performance if you don't fill the
filesystems more than about 70% full. Above 90% you are permanently
fragmenting the filesystem (depends on total size and workload also).
There is the secondary issue that mke2fs can lay out the filesystem
better if it is done right at the start rather than resize2fs doing it in
small increments. I think as long as you are

DepmixS4
Hi I am trying to use depmixS4 package. Based on the documentation, it seems
that depmix allows one to fit an HMM model based on a training data with
time-varying co-variates. However, I did not find any routines which can
help test the accuracy on the fitted HMM model on out-of-sample data.
Can someone confirm if that is indeed the case?
Also are there any alternate packages for the same?
Thanks
