Ars.technica tested Opensolaris 2008.05 in "First look: OpenSolaris 2008.05 a work in progress":

Although the OpenSolaris development community still has a lot of work to do before the operating system is ready to take on Linux on the desktop, the progress so far indicates that the project deserves further attention. We will keep an eye on future releases to see how the platform evolve.

Rolf Kersten managed to install Opensolaris 2008.05 on one of this small EeePC devices. You need some workarounds, but overall the installation is fairly easy with the help of Rolfs article: OpenSolaris 2008.05 on the Eee PC.

The development team for iSER (iSCSI over RDMA over Infiniband) announced, that their prototype is up and running : [iser-dev] iSER prototype implementation is working!!!

Containers in Opensolaris 2008.05 work a little bit different like the ones in the other versions of Solaris. They are an own brand at the moment. Dan Price reports in his article A field guide to Zones in OpenSolaris 2008.05 about the differences.

Was passiert, wenn ein Zug ausfaellt (okay, unbestimmt verspätet, das ist das gleiche wie ein Ausfall, war wohl trotz Feiertag wieder Suicide Monday) und sich dann die Passagiere, die eigentlich eine Fahrt im IC geplant haben, auch noch in einen ohnehin regelmaessig sehr vollen Regionalexpress quaelen muessen. Genau ... Vollkontaktbahnfahren. Wäre dieser Zug an einer Kontrolle für Viehtransporte vorbeigefahren, waere wahrscheinlich der Zug ausser Verkehr gezogen worden.

Oben stehen, unten stehen, auf den Treppen stehen, im Eingang stehen, im Ausgang stehen, vorm Klo stehen und dazwischen die gluecklichen die eine Stufe, eine Lehne oder gar einen Sitz ergattert habe. Dann dazwischen die Leute, die gezwungenermassen ihr Gepack auf einen Sitz stellen muessen, weil die Bahn in ihrer unendlichen Weissheit Zuege bestellt hat, die ueber keine nennenswerten Kofferablagen verfuegt. Die heutige Fahrt war echt zum Abgewoehnen. Ich weiss schon, warum ich versuche zu den Zeiten nach Oldenburg zu fahren, bei denen beide Streckensegmente mit IC befahren werden. Wenn sie denn fahren ...

This is the kind of program i would expect from the public broadcasting system in Germany, not this ever-increasing insult consisting out of game show derviates, daily soaps and half-assed documentaries. When you look at the primary programs in TV you will see the tenth telecast about making a special sausage or how hard it was to transport somebing big from A to B but nothing really interesting.

Okay, back to this movie: This is an really interesting documentary produced by the BBC about Stephen Hawking, the information paradoxon and his actual research.

A hard disk goes down in flames through the atmosphere and specialists were still able to recover 90 percent of the data: Data recovered from Seagate drive in Columbia shuttle disaster. At the end, data seems to be more resistant then most of us believe, when you put a vast amount of effort behind the recovery.

This leads me to annother thoughtgame: Let´s assume, you shredder a disk to pieces as tiny as 1 square millimeter. This would just look like dust to you. A modern harddisk stores 200 gigabit per square inch. One square inch are 645.16 square milimeters. Thus a harddisk would store 310 megabits on a square milimeter. Let´s assume 10 bits per byte (for error correction and similar things) and you have 31 megabytes worth of data on one of these pieces of dust.

It´s just a question of effort to recover the data, when you can yield 10 million euros out of the data (trade secrets, credit card data) it would give you a nice profit when you spend for example 9 million to recover the data. Yet another reason for cryptography everywhere or you may end up with degaussing, shreddering and remelt your old harddisks just to be safe.

It´s a common practice between us admins to look after the load averages. Interestingly the correct math behind this numbers is not really simple. Roman wrote about it at How many kernel engineers does it take to solve one differential equation?. Interesting read.

Der 80igste Geburtstagsfeier meines Grossvaters mütterlicherseits ist hinter mich gebracht, elterliche Grillage im Magen versenkt und jetzt einfach nur noch aufm Balkon oder auf der Terasse sitzen und sich den Rest der Sonne auf den Schaedel scheinen lassen und dann morgen sich in den Zug quaelen.

The new Common SCSI Target Framework made it into build 90 of Opensolaris. In this first integration, the target mode driver for qlogic cards ins included. It´s now really easy to create a FC storage array out of a X4500 and opensolaris. You will find further informations on the project page at opensolaris.org.

2000 downloads of the "Less known Solaris features" book in four days. Pretty cool. I have already some plans for the future. It will stay free under the Creative Commons license. I have no plans to make a real book out of it. One of the next larger projects will be the rewrite of my tutorial regarding the Jumpstart Enterprise Toolkit.

Okay, as the fourth person just asked me about a Amazon Wishlist: Okay, you find it here. This is just for the ones, who really can´t resist. The tutorial is my way to give something back to the community. I didn´t wrote it to get something for. Okay, one important remark: I´m normally i use it as an public "to buy" list for myself. Thus do not wonder, when there are expensive items on it. I´ve tagged them with ignore, so just do that: ignore them.
