Matrix multiplication
Hi,
I have a transition matrix T for which I want to find the steady state matrix for. This could be approximated by taking T^n , for large n.
T= [ 0.8797 0.0382 0.0527 0.0008
0.0212 0.8002 0.0041 0.0143
0.0981 0.0273 0.8802 0.0527
0.0010 0.1343 0.0630 0.9322]
According to a text book I have T^200 should have reached t...

AUC steady state calculations
Hi,
a collegue has send me an excel sheet with some plasma values, and now he wants to know the AUC steady state.
I took a look at the CRAN taskviews, and came up with PK, PKtools, ...
The AUC calculation, no problem with that, but how do I calculate the steady state?
One way of thinking was with the aid of multiple t-test, to find where we couldn't find difference between the different measuring po...

alternative to multiple t-test to find steady-state
Hi,
My collegue has asked me to calculate the steady state of a pharmacokinetic study.
This is defined as where the concentration after a certain time doesn't increase anymore.
So if I perform multiple t-tests between the sample points, with alternative less, then I can see which from which time point there isn't an increase in concentration....

SMB throughput inquiry, Jeremy, and James' bow tie
...rticularly enjoyed the interview with
James and the bow tie lesson at the end. :)
So anyway, I recently upgraded my home network to end-to-end GbE. My
clients are Windows XP SP3 w/hot fixes, and my Samba server is 3.5.6
atop vanilla kernel.org Linux 3.2.6 and Debian 6.0.6.
With FDX fast ethernet steady SMB throughput was ~8.5MB/s. FTP and HTTP
throughput were ~11.5MB/s. With GbE steady SMB throughput is ~23MB/s,
nearly a 3x improvement, making large file copies such as ISOs much
speedier. However ProFTPd and Lighttpd throughput are both a steady
~48MB/s, just over double the SMB throughput.

That's more or less true: generating shared libraries will improve
startup time, not steady-state time. It will decrease steady-state
performance (both for Java and CLI) because the VMs ensure a class will
be fully initialized before its use. Therefore, while the JIT will have
runtime knowledge of a class being fully initialized or not, a static
compiler will have to be conservative a...

busy lamp filed
...isk 1.4 with freepbx installation.
To try the 1.6 version i installd anc configured everything..
Just one thing didnt work so far..
I am using grandstream 2000 and it has a line busy indicator for chef
secretary phones.
But now, this feature does not work.
I can see the line is online..with a green steady light..
But
when the line is busy or DND, it wont change to red light as in previous
1.4 installation..

Noise Cancellation of Server Noise
Has anyone come across a device that could cancel out the noise from servers, ie. the fan noise? I have a server rack near my office and would like to see if i can decrease the noise level. It would seem to me that the steady drone of the fans could be cancelled out to a large extent.

Infrequent but steady NULL-pointer caused segfault in as.POSIXlt.POSIXct (R 3.4.4)
In an optimized build, debug info is just an approximation. It might
help to debug in a build of R and packages without compiler
optimizations (-O0), where the debug information is accurate. However,
first I would try to modify the example to trigger more often, or try to
find external ways to make it trigger more often (e.g. via gctorture).
Then I would try to make the example smaller (not

Problems with TDBs on CTDB-managed Samba instance
...that point, the CTDB cluster came back up successfully and all has been quiet since yesterday afternoon. We notice that gencache_notrans.tdb has not even begun to move toward its (supposedly) pathological high-water-mark size of ~4G. In fact, we have a script watching its size right now and it is steady at ~500K since the restart yesterday:

Xen time drift issues
Hello everyone!
I been observing some peculiar time drift on my Xen domains (dom0 and
domUs). The time (as returned by timeofday) on my domains drifts at
an almost steady rate from the real time ( as read from the time stamp
counter ).
The drift is so constant that it makes me think there should be some
simple explanation for it in the way Xen keeps time.
Some info about my set up:
guest OS: ubuntu
independent_wallclock is set to default 0 on all domains

current zfs tuning in RELENG_7 (AMD64) suggestions ?
...max="1073741824"
vm.kmem_size="1073741824"
vfs.zfs.prefetch_disable=1
However doing a simple test with bonnie and dd, there does not seem
to be very much difference in 4 configs. Am I better off just with
the defaults ? The machine is acting as anoffline storage site, so a
steady stream of data via rsync/ssh
The writes are all within the normal variance of the tests except for
b). Is there anything else that should be tuned ? Not that I am
looking for any "magic bullets" but I just want to run this backup
server as best as possible

[llvm-mca] What's the difference between Rthroughput and "total cycles" in llvm-mca
What is the difference between the two? I thought "Rthroughput" is
basically the number of cycles required to execute a single iteration at
steady state, but this does not seem to match with the schedule/timeline
generated by llvm-mca.
Thanks in advance,
Tom

Infrequent but steady NULL-pointer caused segfault in as.POSIXlt.POSIXct (R 3.4.4)
A reply from stackoverflow suggests I might have hit this bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=14023
I can confirm that this glibc bug affects my system (latest CentOS 7).
However, as far as I know, R is not multithreaded in its core. Is it
possible that some library triggered this?

Physical or Statistical Explanation for the "Funnel" Plot?
...he plot shown at the following location:
http://n2.nabble.com/Is-there-a-physical-and-quantitative-explanation-for-this-plot--td2542321.html
I'm just taking the mean of a given set of random variables, where the set size is increased. There appears to be a quick convergence and then a pretty steady variance out to a set size of 10,0000.
I'm just wondering if there is a statistical explanation out there for this convergence and it has been explored further. Thanks again.
