Talking to Video camera

After solaris became opensolaris, Our team in IEC has got a lot of chance to evangelise solaris
Being the only solaris group in IEC, We have got a lot of chance/opportunities to go to colleges, customers and ISV to brief them about solaris technologies and encourage them to work on Solaris.
I myself has gone to few colleges and given demo, tech talks on solaris

But my experience on last wednesday was quite different. I spoke to camera for the first time.
Vishweshwara Technical University conducts a video educational program for all the associated 120 engineering colleges. It invites companies to give Tech talks through this program
The aim is to get students aware of whats happening in Industries. It is another step to bring the gap between Industries and Institute.

Sun Microsystems India took this opportunity to introduce solaris to students. Though Computer science students have Operating Systems subject in 6th semister, they don't learn Solaris as case study. This course is a step to push VTU to include solaris as a case study in OS course.

It was a 15 hours course. Our talk was scheduled 2 pm - 3 pm every wednesday. Since this was the introduction course, we aimed for all semister/branch students. So the talk was more intended to introduce the technology without going into the internals.

I spoke about Process model in Solaris and Proc tools. My presentation is at
http://vtu.ac.in/~edusat/Prog4/sunmicro/process-model.pdf
I am used to give talk in a open forum and interactive session. So it took a while to get the feel of talking to camera. It was like talking in a auditorium without audience.
If it was interactive session, then speaker can look at audience face and sense if they are following what ever talk is being delivered. But hear there is no such instant feedback. One will not know how many are attending this talk. So even at the end of my talk I was not sure what the feedback was.
The audience were supposed to ask question through forum
http://forum.vtu.ac.in/viewforum.php?f=59&sid=b1f0f5a32dfd20f925923680727da1d2
I got one feedback saying that talk was good. I was happy that atleast one person was there at the other end

Kororaa xgl

I got a Live CD of Kororaa from Moinak. I must say that I am impressed by the 3d desktop.
I read somewhere that there is another 3D desktop model being worked on top of Xorg. But yesterday got a chance to play with it.
What amazed me is that the whole CD is compressed in just 441 MB. It has Firefox and Evolution. It recognized my home network without any issue. It was quite fast on my ferrari laptop.

The first thing I told Moinak after playing with it is "When will get this in Belenix?"
He cooly said quite soon. Now I am waiting for it to be ported in my favorite Belenix.

Auli skiing continued


Second day in Auli


I got up very early in the morning. One thing I do most of the times when I am out traveling (specially in mountains) is to get up very early ( before sunrise ). Some the views of sunrise are breath taking.
I am sure you agree with me since you have seen those sunrise photos.

It was very cold in the morning. I was out with Saurabh taking pictures. There was a layer of cloud on top of Nanda Devi peak. Sun was rising behind Nanda Devi. As soon as we saw some light, the color of the cloud started to change. It was initially red. Then slowly changed to orange. Then bright golden color. I have tried to capture those lights in my camera by spot metering my camera to those clouds. Some the results were really cool.

We had told our instructor that we will report at 9.30 in the morning. But we reached there by 10 am. Kailash had already got Ski for us. We started immediately. Another instructor Pavan was teaching Saurabh. Saurabh was way ahead of us in terms of learning. He was very good in control but his body balance was not that great. He was now learning to turn.

Rest 3 of us were almost in the same phase. But Pramod showed lot of improvements initially. He was able to go some distance without fall. Jalan fell few times initially. But once instructor asked him not to use the sticks and go without them, he got the body balance right. I was in the same state as previous day. Falling most of the time. I felt little bad that I was not able to do it right.
Then I told myself that I can do better. So everytime I start, I was constantly telling myself to keep my body weight front and concentrate on controlling. I did pretty well then onwards.

Now I started to get the feel on skiing. I started going little fast and then trying to control by spreading the heals. I was doing quite confidently now. I was feeling happy about this.
I didn't fall after this point. I was in control all the time.

My next assignment from my instructor is to go down the hill then stop at sometime.
The slope where he was asking me to stop was still tricky. I used to pick speed just before he asks me to stop. But I was doing a good job on slowing down and stopping. Now I was enjoying skiing.

By this time for some reason, Pramod lost the touch. He was going very fast. When ever I watch him, I am pretty much sure that he will fall anytime. He was doing great job to avoid falling sometimes, But his body was not at all in balance. But he was turning very well.

For me turning became little tricky. I was turning easily to my left. But Right was little touch for me. I was doing half turn and then going down the slope. For some reason I right leg was not turning as much as I wanted. But I was pretty much confident that I can do but it is just matter of time.

We came back to Hotel by 3.30 pm. We had asked resort folks to provide gas stove and microwave.
We cooked some MTR ready to eat curries and ordered rotis from Hotel.

In the evening we played TT in the hotel. Hotel manager had told us that they would have a camp fire in the night. So Jalan and myself went down in the night after dinner to see it. Camp fire was about to start. We saw that there was a forest fire in one of the peaks in front of us.

I immediately ran to my room to let Pramod and Saurabh know about it and also got our cameras. We did try to take pictures by exposing for longtime. But none of those photos came good.

This was our last nite in Clifftop resort. We had to vacate as we didn't have reservation from next day. So we were having a long chat on what to do next. There were lots of brainstorming on this.

Some of the places we discussed were
Mussiorie
kasauni
Corbett National park.

Finally after lots of discussion we decided to go to Corbett.

Next day morning we checked out of the hotel in the morning. Saurabh and Jalan went for a half day skiing. I wanted to go around auli and explore. So Pramod and myself took the chair car and went down to GMVN (Ghadawal Mandal Vikas Nigam ). We went to a Hanuman temple. This place was very peaceful. We spent about 30 minutes sitting there and gazing the mountains.

We left Auli in the afternoon to Joshimat. We stayed back in the same Hotel Komet. In the evening Pramod, Saurabh and myself went to Narasimha temple and Shankaracharya Mutt. I was told that Lord Badrinath's Idol (of Badrinath ) will be brought to Joshimat during winter and will be worshiped from
Narasimha Temple. The reason is that during winter it is difficult to reach Badrinath.

We inquired about Bus to Corbett National park (Ramnagar). There was a direct bus but it was in the morning 3.30
So prepared mentally to get up early in the morning and set the alarms.

Travel to Ramnagar  was very long and tiring. It took 15 hours by bus. But I must say that the route was very scenic and had some breath taking views on the way. We reached Ramnagar by 6.30 in the evening.

Ramnagar

Situated in the rich farm belt of Terai, on the southeastern fringes of the great forests, the busy market town of Ramnagar is the main administrative center for Corbett National Park.

We first went to forest department. It was closed. But Jeep drivers there gave all the information
required for us to stay inside National park.


I will talk about Corbett national park in my next and final blog about this trip and also post some photos from Corbett.

A trip to Delhi

Last Wednesday (18th Jan 2006)I got a chance to go to Delhi College of Engineering to give a talk on Opensolaris
DCE were having a Technical festival and Sun had got a 1/2 day slot to talk about its product.
We had 4 talks lined up for the vent

Innovation at Sun,Sun Academic Programs and Participation Invited on Projects
Java Now and Future
Opensolaris
J2ME Cool features

Thanks to Auto Expo in Delhi, all the flights to Delhi from 16th Jan were full. The earliest flight we could get was on 18th Morning 9.50 AM.
Once we got confirmation from my travel agent about the tickets, we requested the college organizer to reschedule the event in the afternoon. Luckily that day they didn't have any event in the afternoon. So they postponed the talk.

It is a 2 and half hours journey by air to Delhi from bangalore. As usual our flight took off at 9.50 AM IST (means it took off at 10.30 am). By the time we reached delhi it was already 1.15 pm. We got out of the airport by 1.30 pm. Our driver told us that it is 1 hour drive to college from Airport.
None of the 2 drivers knew the place exactly. We had to call one of the organizer (Sidharth) and ask for our way. Sidharth gave the directions to the driver. But by his face expression I could guess that he didn't understand any head n tail. He just got one key word, Madhuvan chowki.
So he took us to Madhuvan chowki. Now we started asking people for DCE. In one of the circle, when we asked for directions, the guy said he is also going towards the same college and was kind enough to get into our college and show us the way.
Now comes the interesting part. As soon as he got into the car, he looked at us (Myself and Srikanth) and asked are we 1st year students who are just joining the college. This was something we didn't expect. He made our day. I just looked at srikanth and said yes. Then I started a conversation with him asking about the college, branches, lab, and ragging. He said that he is in 2nd year and there is no ragging in college.

By that time we had already reached college. So he got down at the entrance and Sidharth was waiting at gate to escort us to computer science department.
By the time we reached the hall it was around 2.50 pm. There were still 200 people waiting for more than hour to listen to the talks.
We didn't waste anytime in any introduction. I started off with opensolaris talk.

My agenda was

1) What is opensolaris
2) Why they should look and work on opensolaris
3) CDDL License
4) Source code and tools
5) How they can get involved
6) Resources and documentation

Presentation went well. It was quite interactive. There was lot of questions when I spoke about solaris features in my 2nd agenda item. In the end I also distributed few Belenix CDs. We said a good question will fetch them a CD.

There was another hall with around 50 people(Because this hallw as full). I was asked to give a talk to them also. So I spoke to them too.
By the time we finished our talk it was already 6 pm. SO we rushed back to airport. Our flight was at 7.30 pm. We didn't get anytime to have our lunch. All of us were very hungry. Myself and Naveen wanted to eat Chole Bathure (Delhi is famous for that ). ALl through our way we were trying to call Jet airways to check if the flight is delayed (We all were praying for delay so that we can get sometime to eat). WE got the news that flight is delayed by 45 minutes. So we stopped at Delhi Cant. But we didn't find any good hotels there. So we drove back another 3 kilometers ( where we had seen one nice hotel on our way ) We had some nice Chole bathure. Then got back to Airport. By the time our flight took off it was 8.45 pm. We landed Bangalore at 11.30 pm. By the time I reached home it was 12.30 am.

Hmmm !! It was a long day for me and long blog for you :-)

creating diskgroup in cluster

I was playing with cluster software to reproduce a bug in SPM.
It needed to create a metaset. When I was creating metaset I thought it is good to document it
so that I can use it for future reference also.
What else is the best place than blog ? With blogging I am also sharing the knowledge.
My requirement was to create a metaset with mirrorring.

First to create a metadb
#metadb -afc 3 /dev/dsk/c0t10d0s7

Create a diskset with hostname which can take ownership.
#metaset -s testdg -a -h phys-ruby-1 phys-ruby-2

Add the disks you need to the diskgroup
#metaset -s testdg -a /dev/did/rdsk/d3
#metaset -s testdg -a /dev/did/rdsk/d4

Create a logical devices
#metaset -s testdg d101 1 1 /dev/did/rdsk/d3s0
#metainit -s testdg d102 1 1 /dev/did/rdsk/d4s0

Create a mirrored device
#metainit -s testdg d100 -m d101
#metattach -s testdg d100 d102

My Bushnell Binocular

Finally it is here with me. My new Bushnell Binocular
Ever since I saw Nagki's binocular I wanted to buy one for me
. I had my own constraints in buying one

1) It shouldn't be costly. My budget was < 100 USD
2) It should be atleast 8 x 42 or 10 x 50 (which are ideal for wildlife watching.
3) It should be of good quality (roof mounted, weather proof, fog proof etc )
But buying binocular was not on my priority list as I don't go outings too much these days.
After my trek to Mukurthi and Tusker Valley last month, binocular became number 1 in my priority list.
I did search on the net to find one which could satisfy my above 3 conditions. Finally I found one. Bushnell

It is really cool and exactly fits all my requirements
Another cool this is that Bhphotovideo.com gives a wenger swiss knife free with it
I am big fan of Swiss Army knife. So this made another reason for me to buy this Binocular.
First thing I want to do, is take 2 days off. Get out of bangalore and explore world with my 2 new eyes

Now if you plan to buy the above binocs after reading this blog then don't forget to give me some commision for suggesting this ;-)

Sun Cluster for free ???

There has been quite a few discussion after Sun Announcement
http://www.sun.com/smi/Press/sunflash/2005-11/sunflash.20051130.1.html whether this is applicable for sun cluster too.
The discussion happened in opensolaris forum
http://www.opensolaris.org/jive/thread.jspa?threadID=3988&tstart=0

I think the confusion occured because in the press release by Sun mentions about JES stack being free. But there is no mention of Sun Cluster (popularly known in the market) as free.
There is a mention about Sun Java Availability being free. I think it is nothing but Sun Cluster.
However I need to confirm if we have started calling Sun Cluster as Sun Java Availability suite.

A kumbh ki mele

During the 2nd Day of FOSS.in, a typical bollywood scene happened in the Sun stall.
Our marketing people had hired few hostesses to help in registration etc.
When I came in the morning to set up the stall, I saw this girl. She had a very innocent face.
Her face was very familiar. For a second I thought it is my colleague Shivani.
It was not only me but a lot of us felt the same way. We were wondering if she was Shivani's sister
But from what we knew Shivani didn't have a sister. But all of us had that surprised look on our faces when ever we saw her
I am sure she would have been embarassed by our stares

Shivani came little late to the stall and they saw each other.
Even she couldn't believe her eyes !! The hostess also got a shock. By then the hostess would have gotten an answer for our shenanigans.We were all pouring questions on Shivani if she had a little sister who was lost in Kumbh ke mele ;-)
Shivani also wanted to call her parents to check if she has lost a younger sister. But she didn't have balance in her cell phone
I offered her my cellphone. But in the shock of seeing her long lost sister, she was too stunned to accepted my offer.
Shivani was little anxious in the begining. But later went to spoke to the girl. She introduced herself. But she more eager to know other girl's details.
When the hostess said her name was Priyanka, a localite , and was not lost in any Kumbh ke mele, Shivani heaved a sigh of relief.
I saw Shivani talking to Priyanka for an hour. I bet she was questioning Priyanka for more details and poor Priyanka answering all the questions
I took their photograph. You have to see it to believe it

/>
PS: Latest news is that Shivani is going back home (I guess with photograph to show them to her parents)

Day 4 in FOSS.in

Today was the last day in FOSS.in
I had expected that large number of people will turn out today for the event.
But actually there were very less crowd when compared to other days.

Sun had 3 talks lined up for today.

1) First talk was by Surya on RBAC and Least Privileges features of Opensolaris at 10.30 am
There were little crowd for this talk. This was expected. Jonathan Corbet was talking on Syncronization Premitives at Intel hall during the same time. I too attended that talk for sometime. Since this was a very general talk, it attracted a large crowd.

2) Second talk was by Ganesh on SMF. This talk also had very little crowd because during the same time Alan Cox was talking on Linux Device Drivers at Intel Hall.

3) Dtrace Code camp by Peter Karlsson.
I couldn't attend this talk as I was manning the Sun Stall

Crowd in the stall was also very less in the morning session. By afternoon there was some people in the stall.
FOSS organizers had organised a Rock show in the evening after the event. So most of the people were just hanging out around the expo hall.
I could recognise a lot of people who came to our stall today
During these 4 days, we had a small lucky dip contest. We had 4 locked boxes which had some surprise gifts.
People who visited our stall were requested to fill a form. This form had a 6 simple questions about opensolaris and its features apart from asking their information. People who submit this form (regardless whether they answer the questions correct) were entitled to get a Key. They could try their luck. In case if they couldn't open any of the boxes, they could retain the key and come back next day to try their luck. We were changing the locks everyday. A lot of people came everyday to try their luck.

We winded the stalls by 5.30 pm on the final day. Most of us didn't stay back for the Rock show as we were already tired

When I look back at the last four days, I see a lot of positives for Sun

1) Sun stall attracted a large visitors than any other stalls.
2) Dtrace was a major attraction in the stall. Lot of people were coming back to our stall to know more about Dtrace
I think our engineers Pramod, Prakash Jalan, Sanjeev, Atul, Manoj, Kini, Ramesh, Syed did a great job in answering all their queries and writing D scripts on the fly to prove the Dtrace can do what ever they were asking. 3 cheers to them.
3) We distributed over 1000 Belenix cds and over 400 Solaris 10 DVDs.
4) More than 50% of the people who had submitted the contest form have said YES to join the BOSUG and participate in opensolaris community

This has put a lot of responsibility on us to take this interest to next level

Thursday Dec 01, 2005

Day 3 in FOSS.in

Today is the important for Sun in FOSS.in. We had 4 talks on opensolaris today.

They were

1) Introduction to OpenSolaris by Peter Karlsson
2) Zones - A virtualized operating system environment in OpenSolaris by Sriram Popuri
3) DTrace - Dynamic Tracing framework in OpenSolaris by Peter Karlsson
4) Zettabyte File System in OpenSolaris by Mahesh Siddheshwar

Event was scheduled from 10.30 am till 1.30 pm giving 45 minutes for each talk.
Event was scheduled at Venue Perens Hall which could take 250 people.
It actually started at 10.30 AM. When I entered the hall at 10.20 am. I was little surprised to see about 50 people in the hall. I was surprised because this hall is at the end of the series of halls. While I was walking down to this hall, I saw that all the other halls were relatively empty. By the time talk started we had a quite a good number of about 150 people. I observed that first 5 rows of the hall were occupied. This means that audience were really interested in knowing about opensolaris and not that passing crowd who would hang around for 5 minutes and then walk out.

I put my Sun employee hat and took few photographs of this session and all the other session to show how much opensolaris has created interests in Linux community.
I will post the link for those photos soon.

Peter Karlsson started the talk with the history of How and what Sun has contributed to community. He used NFS, Sun contribution to Liberty Aliance as example. Then he had a slide about Solaris 10 explaining its features.
At this point I was wondering why is he talking about solaris 10 features in this talk. As an audiance my expectation of this talk was to know more about opensolaris community, licensing, compiling, roadmap, university relationship etc. Anyway he spent very little time on this slide and quickly moved to next slide.
While he was mentioning the distribution of opensolaris available, he asked a question.
How many of you have used Belenix ?
I saw about 5-10 hands raising. I could recognise some of them visiting our stall.
Next in the list of talk was about Zones by Sriram.
It coouldn't start in time because he had some issues in getting his laptop working with projecter. This is where I felt that we could have done some planning and coordination well. It made no sense for me. Each person having presentation on his laptop and struggling to work with projector.Why can't all the presentation be put in one CD or load them in one laptop and use it ?

While Sriram was struggling to get the setup, people started to walk out. We lost some people during this time. Before we loose more, we decided to prepone Dtrace presentation by Peter Karlsson. There was quite a few question on Dtrace for Peter Karlsson during his talk. But I couldn't hear the question from the back. I observed this in his earlier talk also. Audience at the back couldn't hear the question.
I felt a microphone could have been provided for the people asking question. Or presenter could have repeated the question for audience
I didn't attend the other 2 talks. But I heard from the people that it went really well.

I was in Sun stall for sometime. The overall crowd for today's event was little less when compared to last 2 days.
FOSS people distributed the T-shirts only in the evening of day 1 and on day 2. By this time most people would have got their T-shirts.May be that is the reason for little less crowd.
I guess people with serious interst and passion on open source were attending todays talk.

We got the Looking glass demo working on Solaris. Thanks to Prakash Jalan. He installed it on a amd64 box. It was well received by the audience.

There was lot of queries on Sun's grid engine. But we didn't have expert with us to talk about it.
So I gave my visiting card to them asking them to forward their queries. I promised them to get back with answer after talking to experts.
We also had our first BOF session. It was on Dtrace. I couldn't attend that. But I heard from Sanjeev that it was a good and extensive discussion about Dtrace.

Tomorrow is the final day for this event. We are having a talk on
1) Solaris 10 security
2) SMF
3) Dtrace code camp.

Hope to see similar response for tomorrows session also.

More about FOSS.in on second day

I finally figured out how to format in blog. Thanks to Pratap. I guess now my blog is much more readable. I still need to figure out how to upload the photos.

Today there were lot of queries about Looking glass demo. We initially had thought about demoing it. But for some reason we dropped it. After seeing so much interest, One of my colleague actually got a Live CD with looking glass on it working. Right now I have booted a laptop with this LiveCD. It is cool. But the problem with demoing is it runs on linux. We still need to get the looking glass on solaris

Another interesting point about today's event, is some of the main guys behind FOSS event trying out Belenix.
In the evening I saw them near our stall discussing on something, they had belenix on their IBM thinkpad. This is something cool news for opensolaris community.It would be really cool if they also join our community
