I did some tests with that array, as I did with an Infortrend OXYGENRAID device and an old LSI FC array.
With patch 137137-09 (SPARC) and 137138-09 (x86), Solaris 10 can handle zfs pools with version 10. You will have to upgrade your zpools; "zpool status" will result in this warning:
To upgrade, use the command
The GZIP compression known by OpenSolaris and Solaris Express is now in the Solaris 10 code base starting from (kernel) patch 137137-09/137138-09.
You may set:
and - to set a gzip compression level:
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.To upgrade, use the command
# zpool upgrade yourpoolnameThe GZIP compression known by OpenSolaris and Solaris Express is now in the Solaris 10 code base starting from (kernel) patch 137137-09/137138-09.

Congratulations for your unbeatable victory. May god give you all you need to reunite your country and to solve many of the problems.

As I take trains in Germany very often, I just took these two photographs of a glossy display (on an ICE train) and a matte display (on a local commuter train).
Looking at the market (and even Apple does this now), glossy display are everywhere. In my opinion, they are unusable. Perhaps at home, in a dark room to present a movie it is ok. But not for everyday's work.

I wrote this blog entry just sitting in this train (ICE 180). Internet is no problem because of EDGE/GPRS or 3G (UMTS) available nearly everywhere.
Just look at this glossy display. Perhaps it is a nice gadget for design students, but not for serious work.

This is an example of the displays in the local commuter train circulating from Weinfelden (Switzerland) to Singen or Engen in Germany. I think this is a good example of a matte anti-glare display.
The little village's name is "Niababli" or just "26" (vingt-six), and it has some wells to retrieve ground water. Google Maps has still the old route in his label map. (Niababli is on the center of this map).My sole connection to Germany was a short wave receiver to listen to the "Deutsche Welle" station at night and the BBC world service. Sometimes I got some broadcasts from Voice of America as well.
Life is so totally different from what I ever saw in my life. Men are working on the fields, harvesting cacao, maniok and rice, the women are cooking on the field for the workers (it is a really embarassing for an employer to have nothing to eat for his employees here!).
My friend and me had the chance to live in a house built by her father, which was a brickhouse quite confortable. Because of malaria, the bed was entoured by a mosquito net.
On the evening, people came back from the fields, talking, keeping their families, drinking a beer in a "maquis" (the name of bars with food). The sound of the evening is the one of small power generators, running on diesel or gasoline to run the little cinema or some light bulbs.
And then you see that warm attitude, this charming reception of the people here. Nobody was hostile towards me, nobody had fear. I became quickly "le petit blanc" (I was among the tallest person in the village ...) and many children were already at 6am (they have London Greenwich time there) on our patio to wait for me. Children everywhere. Women make children when they want. And it has nothing to do with marriage. Educating children is the job of every adult. And: The children of a brother are like the own children and like these of the sister. The "little family" with "father, mother, children" is not existent.
Every child attends school here (which was financed and built by Germany here in the village) and continues school in Sassandra (the next city, 21km away) where they can go up to the bac (needed for university education).
Many leave the village when they reach that age to find themselves in the bigger citites.
All speak french fluently and most parents also teach them their native language. In this small village, three of them exist - and they are totally different and incompatible. French is the only language they can use to talk to other ivorians living in the state of the Ivory Coast.

The first thing you'll notice in Ivory Coast is that chinese products are invading the country. You nearly have no chance to get a normal socket extension (to connect 5 devices to a single wall socket; something you'll find in the US or Europe für $1.99), you are left with the choice of a chinese "blinkenlights" product with a spinning "voltmeter" in it (showing you nothing) and many switches on it. Included a random algorithm which voltage will be the result and which person will be electrocuted next.
Examples: A bad iPhone copy and one of these "socket extenders":
Why we don't sell our products there? How the chinese have adopted that market so rapidly?

After three weeks in Ivory Coast I am feeling lucky that all went well and - on the other side - it hurts that I don't see my friends there any more.I little photo album will follow and some remarks.
So no great updates will occur from Sunday, September 14th to Sunday, October 5th. After so many vaccinations and Lariam I am ready....
Il n'y aura pas de mises à jour pendant la période du 14ème septembre au 5ème octobre. Je sera en Côte d'Ivoire pour des visites - sans ordinateur et sans boulot. Enfin.

are fascinating: People spent millions of dollars to have "crystal clear" pictures and now we're on HD, but everybody enjoys Youtube... Videos encoded with 320x240 pixels and scaled to 415 pixels wide while playback...
Nevertheless, I have a youtube channel now and I've put these zfs block pattern movies in there, resized to "youtube-ready"-size.

Two mirrored volumes concatenated to give a 8TB storage pool. I logged 18 hours of block read/write activity and made a MPEG4-Movie out of it.
Green pixels summarize sector reads, red pixels sector writes. Each pixel represent the same number of consecutive storage blocks. The pixels are doubled in height because of the 4:2:0 color coding of MPEG4. Otherwise, a red pixel adjacent to a green one could not have been possible, as two lines are coded together with regard to color. It is a TV format, after all..
At half past eight, a backup job started, scanning many files. After 4 o'clock an expire run is started. And at 5 o'clock it is really "night" with user activity rebeginning at 6:30.
I used 640x480 pixel frames with 30 frames per second. Should be possible to watch on a NTSC TV :-) Enjoy!

As a followup to this article, I used a zfs volume and an ufs volume with an application doing the same work on both partitions (replicated sql engines).

But let's start from the beginning. You may however start to play with them!
You are using Cyrus SASL for authentification purposes? Supposedly with the Cyrus IMAP server or Postfix (the two major applications using Cyrus SASL)? Then you'll know the problem: You may use saslauthd(8) to connect to an authentication database as Unix PAM or LDAP. Problem: You will only be able to use plaintext logins. Why?
If using saslauthd, the SASL-enabled server gets the password given by the user/client, and asks saslauthd whether it is correct or not.
Plaintext authentication can be sufficient when using it with SSL/TLS. In IMAP environments this may be a good solution if all mail clients can be configured in that way. With SMTP you will have a problem. Many Mailservers being able to initiate authenticated outgoing SMTP connections do not use SSL/TLS. Many of them want to use CRAM-MD5 as it is defined in many standard drafts.

The famous "Landessender Beromünster" will shut down on Dec 28th. The name of the little city "Beromünster" was known throughout Europe, as it was marked on many radio scales of the last decades. It's frequency is 531kHz (since 1978).
Beromünster started broadcasting on June 11th, 1931. After 77 years of operation, its end is near.

Scenario: Two ISDN phones (a wireless DECT one and a comfortable one with cable) are to be connected to my Asterisk server which calls out via IAX2, SIP and ISDN.
As my mini case (which contains a VIA embedded board) does only have one PCI slot (via riser card), I chose the BN2S0 from BeroNet (Berlin).
It features a Cologne Chipset Design HFC chipset with 2 S0 (ISDN S/T) interfaces (click to enlarge):
Each port has to be configured for NT (acting as a phone line) or TE (acting as a client/phone device) mode.

You will need an MySQL Database Version 5 or greater (for InnoDB performance), perl with DBD::mySQL and Digest::MD5, and Postfix capable of using Policy servers.
With this update, changes to the whitelist databases (postmap) are detected automatically. The literal script in the former blog article was updated also.
