CZOSUG OpenSolaris 2008.11 Training

Czech OpenSolaris User Group a.k.a. CZOSUG decided to focus on the beginners and people generally unfamiliar with OpenSolaris for the school year 2008/2009.

Our first event organized with great help of many people from the community happened on Saturday December 6th, just one week after the OpenSolaris 2008.11 installation images were made available for download, but few days before Sun officially announced it.

We decided to call the event simply OpenSolaris 2008.11 Training, reserved a room in Prague Sun offices, made the event free for all attendees (space was obviously limited to ~ 40 people), paid the pizza lunch and drinks, and waited…

The agenda of the training was simple:

  1. Get OpenSolaris installed, bare metal, virutalized, whatever is prefered.
  2. Get the people understand main differences between Linux and OpenSolaris.
  3. Get hands-on familiar with ZFS, p* commands, package manager.

The training was fully booked just three days after we announced it via various mailing lists and websites, and we unfortunately had to decline registration of several guys.



The room was full of friendly people with laptops, and to my surprise, only few of them got to know about the training through the CZOSUG mailinglist. Most of the people were Linux users, perfectly fitting into our target audience. Also to my surprise, most of the people who attended never played with OpenSolaris before. This was a perfect fit for a small competition we organized. The goal was to draw the new OpenSolaris logo, as close as possible.



What counted was the total number of circles, number of leaky circles, and eventually their color. Needless to say, no one did it right :). The best people actually guessed the numbers, but getting the layout and colors right seems just impossible.

The talks were all fine, people had great questions and we tried to answer them responsibly. I have to really thank here to all the people from the community who helped us to drive the lightning talks section, namely:

  • Luboš Kocman - lightning talk about IPS
  • Tomáš Mann - lightning talk about DTrace
  • Jan Hlodan - lightning talk about Distro Constructor



It’s my pleasure to announce that we have received very very positive feedback for the training and that we are planning to repeat it during the first half of 2009 in various cities around the Czech Republic. The slides of all talks are now posted on our website.

If you are interested in having this training in your city, all we need you to do is to help us by getting a free room for ~ 40 people with internet connection and electricity, we in turn offer professional speakers and food/drinks coverage. Just don’t be afraid to get in touch with me directly.

CZOSUG News for school year 2008/2009

It’s been a while since I blogged about OpenSolaris. After successfully closing the OpenSolaris Developer Conference 2008 we all needed a break to refresh. We have been talking a lot about what to do next with CZOSUG, how to perhaps attract more people, and how to make our events more fun.

After looking at the impressive list of events on many advanced Solaris/OpenSolaris topics that CZOSUG organized during the past years, and after chatting with a few guys from the community (you know who you are :)), it turned out that lot of basic questions about OpenSolaris remains unanswered.

During one of our informal pub sessions we for example realized that no one is able to answer the question whether a raidz2 zfs pool created on a bunch of USB sticks will reconstruct itself correctly when USB sticks are reconnected to another computer.

We took out laptops out (still in a pub), quickly verified that zfs indeed works as expected, and concluded that we have to get back to the basics.

The goal for CZOSUG school year 2008/2009 was set to help people migrating from Linux or other operating systems to get quickly familiar with OpenSolaris.

Timing was perfect, as 2008.11 was just about to hit the streets, so our very first event we started to plan was an OpenSolaris 2008.11 Training.

Let me summarize this event in a separate post, and let me quickly announce that the event was very successful and that we are planning to repeat it in a few other big Czech cities during the first half of 2009.

OSDevCon 2008: Register Now!

I’m happy to announce that we have completed everything and we are ready for the conference. The last remaining bits with the VISA payment system have been sorted out and we have successfully opened registration for the visitors. Here is the official announcement Dirk has sent out on May 15.



I thought I’d share with you some more organization details.

The full conference program covers two days and the Wednesday is reserved for the tutorials. At the moment we have four half-day tutorials available.

Every conference attendee will get a conference bag with printed proceedings and some small things from the sponsors, these are not finalized yet. More importantly, the conference registration fee contains full lunch for both days of the conference in the conference venue itself, so that we don’t need to hop around and search for food and we can still continue chatting over the lunch breaks. On Thursday evening there will be a social event: a boat trip through the historical center of Prague on the Vltava river with the dinner and some beers.

And of course we have the discounts. Although we advertised discounts for the students and for the GUUG, NLUG, and CZOSUG members only, this does not mean that we are not offering discounts to other OpenSolaris User Groups members. Just don’t be shy and get in contact with us.

So if you have not registered yet, do it now as the venue hotel rooms are filling up quickly.

Looking forward meeting you in Prague.

OSDevCon 2008 Call for Papers closing soon

The organization team of the OpenSolaris Developer Conference 2008 was rather busy over the past months. It looks like we are approaching the deadline for paper submissions, so if you haven’t already submitted your presentation, do so now. If you did, than thanx a lot, all the submissions we received are looking to be of a very high quality, and we are going to meet quite a few interesting people. Stay tuned.



We also did a bit on the marketing front. The image you should see above is one of the official conference banners that you are free to use on your website if you would like to help us to spread the word. And since we are community effort relying on sponsorship money only, we will really appreciate that.

And last but not least, we are almost ready to open the registration for visitors that will allow you to book your hotel, pay your tickets, and plan your stay in Prague. You will hear from us soon.

Cuba: closed & melancholic

One of the pictures that represent Cuba in its whole reality. Beautiful land and beautiful people suppressed by the regime. Just compare that with India.


Princess from Cuba

I’m now going to be busy in the dark room enlarging all the portraits I have shot there.

India: open & optimistic

This is one of the pictures I have taken during my last stay in India. For me, this picture represents the whole beauty of Indian country. Especially when compared to Cuba.

vim: command not found

The dark days of OpenSolaris are gone. From build 78, VIM, a powerful editor of choice for many programmers written by Bram Moolenar, will become part of Solaris Freeware Consolidation.

In short that means that you should not see the familiar vim: command not found message anymore. VIM will become part of SXCE build 78, it should be in the next SXDE that will be released spring 2008, and I hope that Project Indiana will pick it up soon.

The putback was done by one of our colleagues, Martina Tomisova from Sun Prague last Friday and we celebrated it today by eating Indian sweets.

The Swiss Army Knife of Data Storage

Title says it all. Nexenta Systems Inc., the company behind Nexenta Operating System, a powerful combination of OpenSolaris Core and Debian/GNU Linux packaging system and user land applications today announced availability of the NEXENTASTOR APPLIANCE.

It is based on OpenSolaris, it is based on Debian/GNU, it features ZFS root/boot configuration, transactional apt-get dist-upgrade side by side with zpool snapshot.

And if I’m not mistaken it is the first commercial product based on OpenSolaris and not being produced by Sun Microsystems.

Nexenta & Indiana @ BOSUG

Here is Moinak talking enthusiastically about the Project Indiana at October BOSUG Meeting where I had a chance to talk a bit about the Challenges and Future Plans for Nexenta.

Moinak talking about project Indiana

The audience was very open asking a lot of questions and discussing with smile on their faces various aspects of open development of OpenSolaris.

At let me say it straight, no matter how much we all expect big things from Indiana, we all agreed that the way it is communicated and developed is not very community like. Did I hear someone say something about Sun throwing the source code over the wall?

Let’s hope this will change as more and more code becomes available for the public to see.

Here are the pictures I captured, and there is the rest from Milan.
