Avoiding loops to detect number of coincidences
Hi all,
I have this information on a file ht.txt, imagine it is a data frame without
labels:
1 1 1 8 1 1 6 4 1 3 1 3 3
And on other table called "pru.txt" I have sequences similar this
4 1 1 8 1 1 6 4 1 3 1 3 3
1 6 1 8 1 1 6 4 1 3 1 3 3
1 1 1 8 1 1 6 4 1 3 1 3 3
6 6 6 8 1 1 6 4 1 3 1 3 3
I want to now how many positions are identical between each row
in pru compared with ht.

changing the drawing context using Cairo and RGtk2
I am not too familiar with Cairo and RGtk2 and have the following problem:
I have a container with two GTK drawing areas converted into Cairo devices.
I know that I can set the current drawing context e.g. using dev.set().
But this is tedious. How can I set the context using the objects da1 or da2?
w <- gtkWindow()
w$setSizeRequest(400, 400)
vbox <- gtkVBox()
da1 <- gtkDrawingArea()

4.8-RELEASE not identifying scsi drives
A problem with 4.8 reported by myself and Aaron D. Gifford.
Anyone in -stable who knows more?
********
I'm assembling a Compaq 1850R with attached storage system. For the
built in scsi controller (sym), there are three drives internally on
channel 1 + 5 drives externally on channel 2.
During boot, I can see all disks being identified first by the machine
itself and then in the early part

device name changing
Hi.
If I create a zpool with the following command:
zpool create tank raidz2 da0 da1 da2 da3 da4 da5 da6 da7
and after a reboot the device names for some reason are changed so da2
and da5 are swapped, either by altering the LUN setting on the storage
or by switching cables/swapping disks etc.?
How will zfs handle that? Will it simply acknowledge that all devices
are present and the pool is

Dump Card State Begins ...
Hi ...
Can someone tell me whether or not this is indicative of a hardware, or
software, problem? It happened a few times today, on two different
drives, and it seem to "self-recover", since the server is still purring
along without any noticeable problems:
neptune# grep "timed out" /var/log/messages

make_dev_physpath_alias
Hello all.
I have a supermicro 16 bay box with a LSI 9211-8i card.
We use it for temp data storage, and we wanted to try the l4z compression.
After updating the source tree to r247839: and doing a make buildworld
cycle all works fine.
But at boot time we get some warnings.

Failure of gvinum after panic
Hi all,
I have some problems with my gvinum setup after the system panic'ed.
Afterwards the system fails finding the plexes to the subdisks (or at
least that is what I can understand after having searched the gvinum
source code for the error string in the DMESG log..)
The machine is an IBM Netfinity 5000 and the internal HW self tests
does not find any errors in the hw.

Error t value matrix
Hi all,
I want to make the following:
I want to run a linear regression on each column of a matrix "estima" on
the correspondent column on the matrix "estima2".
You see I want to regress estima[,1] on estima2[,1] this way to all
columns....
At the same time I want to make a regression adding each time a new
observation.
You see, the first regression will regress only one

FreeBSD 8.3-R sysinstall does not "see" disks that are recognized during boot
I've got a new supermicro server I'm trying to get FreeBSD on. It uses the
Intel c602 chipset, and it's my understanding that support for that
chipset (c60X) was recently added via the isci driver. Ok, great, that
explains why 8.2-R and 9.0-R didn't see the drives.
So, I grabbed the memstick image of 8.3-RELEASE that is on the ftp server,
booted it up, and sure enough, as the

I have seen that R can be switched on to a Broker called IB.
There is another one similar to IB that permits to make a "code" and send
orders to broker to buy or sell stocks?
Can be done trough R, writte in excel and trough API sell/buy to the broker?
Can someone send me an example (easy example?)
Many thanks.

RAID10
Hi All,
I am looking at ZFS and I get that they call it RAIDZ which is similar to RAID 5, but what about RAID 10? Isn''t a RAID 10 setup better for data protection?
So if I have 8 x 1.5tb drives, wouldn''t I:
- mirror drive 1 and 5
- mirror drive 2 and 6
- mirror drive 3 and 7
- mirror drive 4 and 8
Then stripe 1,2,3,4
Then stripe 5,6,7,8
How does one do this with ZFS?

Health check
Hi
I have a quad processor Compaq Proliant 5500. The output
from dmesg seems strange (I have also sent a copy to
freebsd-smp to ask about smp issues) and there are also some
performance issues which I suspect are smp related. Could
anyone who fels so inclined please take a look at the output
and let me have any comments.
Thanks
