A Tech talk by Angelo

Posted: July 31, 2007 in Sun Stuff, Techstuff

Yesterday as a part of Sun Club activities there was a tech talk by Angelo Rajadurai, Sun Microsystems, Santa clara. He is an alumni of our college and has 14 years experience in Sun and DTrace traveling evangelist for two years. His talk was really inspiring and very simple that we felt easy to understand the concepts.

He gave an introduction to Solaris, Open Solaris. He spoke few words on Niagara. The major areas that he was speaking were ZFS and Dtrace. He explained very clearly the concepts of ZFS-Zettabyte File System a 128 bit filesystem and Adavanced filesystem on the planet.He explained how ZFS differs from other traditional filesystems. He was throwing lights on the immense capacity of this file system, its properties like copy-on-write, sharing, data integrity and transactional operation, snapshot, self healing. I was really impressed by the concept of pooling in ZFS in which there are no partition kind of stuffs and all the filesystems can share the same pool.He ran few commands on zfs and showed how to create a filesystem for particular user in zpool , list the filesystems of all the users in zpool, how to allocate space for each filesystem in the zpool, how to restrict the access of an user in the zpool and how to take snapshots.He explained how Raid-Z in zfs overcomes the problem of write-hole in Raid-5 by its property called copy-on-write.Due to the presence of copy-on-write property there is no need of fsck for file checking as the consistency of data is always maintained.

Next he gave a brief introduction to Dtrace – a dynamic tracing tool and powerful featues of it.Dtrace can trace any applications, system calls or even the Operating system itself.He showed how to enable a probe and list the probes and explained the terms provider, module, function, and name. He worked out few commands on Dtrace. We had a clear introduction to Dtrace. He wonderfully answered the questions thrown by our students. While ending up the session he spoke on Web 2.0. He gave the scope for projects that can be done as a contribution to the Open Solaris community and said that he is ready to mentor the students from our college.We got good exposure to Dtrace and ZFS from a great person.That was an awesome day.

I had Solaris express in my laptop with CDE-a proprietary desktop environment which sounded little bit difficult to use. Once I subscribed for Solaris10 DVD in Sun site. I got it this month through air mail. After finishing my semester exams I tried installing it. Now I have got a Solaris with JDS(Java Desktop System) environment uses free software.It is based on GNOME2.6.It gives a look and feel of a windows environment which can attract ppl.

Its really cool!!!.. Have got Sunstudio dvd also.Yet try those stuffs.Sun stuffs–Keep rocking!!!!..U can subscribe for Solaris DVDs, Sun Studio,Live CDs here

Sun Club Inauguration

Posted: February 24, 2007 in Sun Stuff, Techstuff

Last Friday, we had Sun Club Inauguration in our college. Principal was expected to inaugurate it but unfortunately he was not able to make his presence there. We also invited all the Deans and HODs, students of all departments. The function took place at K.M.Auditorium of our college. There were around 400 students. The HOD of our department Mr.Rajaram spoke about various companies that have collaboration with our college. Then the HOD of IT department spoke on his experiences in the computer world. Next was the presentation on Sun Club by my ambi(keerthi). She was listing various activities that will be performed in Sun Club. She was speaking on some certification courses and about the cool products(Open Solaris,Netbean and Java) from Sun. A mailing list for Sun club has also been created. So people can subscribe to Sun club here.At the end of the inauguration many students registered in Sun Club.The Staff co-ordinators of Sun Club Mrs.Subathra and Mr.Emil selvan took good initiatives and they helped us a lot.

Hello folks meeting u after a long time. A few weeks back , my friend keerthi-the ambassador(I call her ambi) from Sun Microsystems to our college started her Ambassador initiative program with the second year and first year students of CSE and IT department of our college. We friends agals,bala,ashok,ananth and myself were helping her in this. During this session an introduction to the company Sun MicroSystems was given and then the cool products of Sun like OpenSolaris , Java and Netbeans were given. Even we ppl didn’t have much knowledge in the areas like Solaris and Netbeans. The audiences were the first and second year students among which most first years don’t know what is an operating system. Even though the presentation was simple enough it was too hard to reach them. Then something about the certification courses from Sun and about the mailing list( Open Solaris User Group]) were told.

Bala was giving a demo on Dtrace and Belenix to the students.

Finally we had a chance of interacting with all the students individually. They felt that they were new to these technologies and they wanted to know it from scratch. They are mailing and asking when the sun club will formed and they are eager to join it. I don’t know whether this interest will last for long time.

So as soon as possible a mailing list for sun club has to be created and the Sun club Inauguration has to be done soon. We are planning to host an site for Sun club based on the response.I like to be a part of this club and help my keerthi in her job.I have got an good opportunity to know all these technologies through this.

We have prepared a road plan of this program and hope that will end up in success.
